3 Section 1: Appropriate Use of HT 2004 Patient ManagementPatient Management Issues in MenopauseSection 1: Appropriate Use of HTThe Women’s Health Initiative (WHI) has created considerable confusion and controversy regarding the use of postmenopausal hormone therapy (HT; estrogen [E] alone or combined with a progestin [E+P]) among physicians and especially among patients.This slide library is designed to discuss the appropriate use of postmenopausal HT, to review common concerns and patient barriers to HT, to describe techniques for individualizing postmenopausal HT, to identify alternative therapies for postmenopausal women, and to discuss methods of addressing patient concerns.
4 Reasons Women Gave for Initiating or Continuing HT 2004 Patient ManagementReasons Women Gave for Initiating or Continuing HTMenopause-related SymptomsOsteoporosis, Bone Loss, Fracture PreventionDoctor Prescribed It, Told Me to Take ItCardiovascular Disease PreventionOtherDepression, Anxiety, Emotional Distress102030405060Although the use of postmenopausal HT has changed since the WHI, the most common reason women initiate or continue HT has been and continues to be to relieve menopausal symptoms.1In this telephone survey of 1082 US women (aged 50 to 80 years) conducted in 1995, the reason most frequently cited by current users of HT (n = 460) for initiating treatment was menopausal symptoms.1More recently, in 2003, a study was undertaken to describe the experiences of postmenopausal women who try to stop HT and to identify characteristics associated with inability to stop.2 Grady et al conducted telephone interviews with 670 of 1000 randomly selected female members of the Kaiser Foundation Health Plan, aged 50 to 69 years, who regularly used HT for at least 1 year before July 1, Of these 670 women, 377 had attempted to stop using HT between July 2002 and the time of the interview (March 2003).Of these 377 women who attempted to stop using HT after July 2002, 280 (74%) had not resumed HT at the time of the interview; 97 women (26%) had resumed their use of HT at the time of the interview. The major predictor of resuming HT was the development of troublesome withdrawal symptoms (OR, 8.8; 95% CI, 4.9–16.0).Women with a hysterectomy who had used HT for 10 years and who started HT mainly for reasons other than health promotion were more likely (P < .001) to resume HT use (44%) compared with those with one or two (25%) or none (9%) of these three characteristics. Most of the women (72%) reported they had stopped HT abruptly; 28% reported they had tapered off HT. No differences were observed in the incidence of troublesome withdrawal symptoms or the proportion of women who resumed HT between these two groups.These results suggest that approximately one-quarter of women who try to discontinue HT may develop troublesome withdrawal symptoms that may require the resumption of treatment.PercentageNewton KM, et al.

5 FDA-Approved Indications for HT 2004 Patient ManagementFDA-Approved Indications for HTTreatment of moderate-to-severe vasomotor symptoms associated with menopauseTreatment of vulvar and vaginal atrophyPrevention of postmenopausal osteoporosisPostmenopausal HT is indicated forTreatment of moderate-to-severe vasomotor symptoms associated with menopauseTreatment of vulvar and vaginal atrophy*Prevention of postmenopausal osteoporosis†The treatment of menopausal symptoms remains the primary indication for HT, and is the most common reason why women initiate therapy.Since the WHI was not designed to evaluate the indicated uses of HT, the overall risk/benefit profile of HT cannot be assessed from the results of the WHI alone.*The Food and Drug Administration (FDA) suggests that topical vaginal products should be considered when prescribing HT solely for the treatment of symptoms of vulvar and vaginal atrophy.†The FDA also encourages the consideration of non-estrogen medications when HT is prescribed solely for the prevention of postmenopausal osteoporosis.FDA Guidance for Industry.

6 Women’s Health Initiative (WHI) Updated Results Summary: Breast Cancer 2004 Patient ManagementWomen’s Health Initiative (WHI) Updated Results Summary: Breast CancerFor invasive breast cancer, HR = 1.24 (95% CI, 1.01–1.54; P = .003) after 5 years of E+PFor total breast cancer, HR = 1.24 (95% CI, 1.02–1.50; P < .001) after 5 years of E+PExclusion of women with prior HT use (26.1%), HR was nonsignificant at 1.09 (95% CI, 0.86–1.39)Analysis of breast cancer data showed slightly larger tumors (1.7 cm with E+P use vs 1.5 cm with placebo) and ~10% more regional node positivityThe WHI, a large, randomized, placebo-controlled study of risks and benefits of E alone and E+P as preventive therapies for postmenopausal women, enrolled 27,000 women between 1993 and 1998 and was scheduled to conclude in A total of 16,608 women were randomized to the E+P portion of the trial and received mg/d CEE with 2.5 mg/d MPA or placebo.In July 2002, the Data and Safety Monitoring Board (DSMB) of the WHI discontinued the HT arm of the study after an average follow-up period of 5.6 years because the design-specified, weighted, log-rank test statistic for invasive breast cancer (z = –3.19) crossed the designated boundary (z = –2.32), and because the global index (a summary measure of the overall balance of risk and benefits of HT) indicated that the risks of HT may exceed its benefits (z = –1.62).In intent-to-treat analyses, E+P increased total (245 vs 185 cases; HR, 1.24; weighted P < .001) and invasive (199 vs 150 cases; HR, 1.24; weighted P = .003) breast cancers compared with placebo.Data suggest that women reporting prior HT use may have had a greater risk for breast cancers associated with E+P use than never-users (for never-use, HR = 1.09; <5 years of prior use, HR = 1.70; 5 years of prior use, HR = 2.27).The invasive breast cancers diagnosed in the E+P group were similar in histology and grade but were larger (mean [SD], 1.7 cm [1.1] vs 1.5 cm [0.9], respectively; P = .04) and were at a more advanced stage (regional/metastatic 25.4% vs 16.0%, respectively; P = .04) compared with those diagnosed in the placebo group.After 1 year, the percentage of women with abnormal mammograms was greater in the combined therapy group (716 [9.4%] of 7656) compared with the placebo group (398 [5.4%] of 7310; P < .001).Chlebowski RT, et al.

7 WHI Updated Results Summary: CHD, Fracture, Dementia 2004 Patient ManagementWHI Updated Results Summary: CHD, Fracture, DementiaCHD data failed to show significance with adjudicated overall 5-year results (HR, 1.24; 95% CI, 1.00–1.54)1In addition to hip fracture reduction, vertebral fracture was significantly reduced in a non-osteoporotic population (HR, 0.60; 95% CI, 0.38–0.95)2Dementia increased in women who initiated E+P at age 65 years (HR, 2.05; 95% CI, 1.21–3.48; P = .01)3Additional 23 cases/10,000 women/yearNo increase in mild cognitive impairmentManson et al1 reported final CHD outcomes from the WHI. E+P was associated with a nonsignificant HR for CHD of 1.24 (95% nCI, 1.00–1.54; 95% CI after adjustment for sequential monitoring, 0.97–1.60). The elevation in risk was most apparent at 1 year (HR, 1.81; 95% CI 1.09–3.01).Cauley et al2 evaluated whether fracture risk reduction with E+P differed according to risk factors for fractures.733 women (8.6%) in the E+P group and 896 women (11.1%) in the placebo group experienced a fracture (HR, 0.76; 95% CI, 0.69–0.83; did not differ in women stratified by age, BMI, smoking status, history of falls, personal and family history of fracture, total calcium intake, past use of HT, BMD, or summary fracture risk score).Total hip BMD increased 3.7% after 3 years of treatment with E+P compared with 0.14% in the placebo group (P < .001).Thus, E+P increased BMD and reduced the risk of fracture in healthy postmenopausal women.Shumaker and other investigators for the Women's Health Initiative Memory Study (WHIMS)3 evaluated the effect of E+P on incidence of dementia and mild cognitive impairment (a secondary outcome operationally defined as poor performance on modified Consortium to Establish a Registry for Alzheimer’s Disease [CERAD] tests in 1 area of cognitive function, a report of some functional impairment but not in activity of living, no evidence of psychiatric disorder or other medical condition causing the cognitive decline, absence of dementia) compared with placebo. Of the 4894 eligible participants of the WHI study, 4532 (92.6%) postmenopausal women free of probable dementia, aged 65 years were enrolled in the WHIMS (n = 2229, E+P group; n = 2303, placebo group).Overall, 61 women were diagnosed with probable dementia, 40 (66%) in the E+P group, 21 (34%) in the placebo group. The HR for probable dementia was 2.05 (95% CI, 1.21–3.48; 45 vs 22 per 10,000 person-years; P = .01), resulting in an additional 23 cases of dementia per 10,000 women per year. Alzheimer’s disease was the most common classification of dementia in both study groups.Treatment effects on mild cognitive impairment did not differ between groups (HR, 1.07; 95% CI, 0.74–1.55).CHD = coronary heart disease.1Manson JE, et al.

8 WHI Updated Results Summary: Gynecologic Cancers, QOL 2004 Patient ManagementWHI Updated Results Summary: Gynecologic Cancers, QOLCancer (after 5 years of E+P)1Endometrial: HR = 0.81 (95% CI, 0.48–1.36, NS)Ovarian: HR = 1.58 (95% CI, 0.77–3.24, NS)No significant improvement in health-related QOL found in largely asymptomatic women (average age, 63 years)2Small subset of symptomatic women showed improvement in hot flushes, small benefit in sleepAnderson et al1 evaluated the risk of gynecologic cancers and related diagnostic procedures among women assigned to E+P and placebo in the WHI.In 5.6 years of follow-up, there were 32 cases of invasive ovarian cancer (HR, 1.58; 95% CI, 0.77–3.24), 58 cases of endometrial cancer (HR, 0.81; 95% CI, 0.48–1.36), 1 case of non-endometrial uterine cancer, 13 cases of cervical cancer, and 7 cases of other gynecologic cancers. No appreciable differences were found in the distributions of tumor histology, stage, or grade for either cancer site. The incidence of other gynecologic cancers was low and did not differ by randomization assignment.Hays et al2 explored the effect of HT on health-related quality of life (QOL).Randomization to E+P resulted in no significant effects on general health, vitality, mental health, depressive symptoms, or sexual satisfaction. The use of E+P was associated with a statistically significant but small and not clinically meaningful benefit in terms of sleep disturbance, physical functioning, and bodily pain after one year (the mean benefit in terms of sleep disturbance was 0.4 point on a 20-point scale, in terms of physical functioning 0.8 point on a 100-point scale, and in terms of pain 1.9 points on a 100-point scale).At 3 years, there were no significant benefits in terms of any QOL outcomes. Among women 50 to 54 years of age with moderate-to-severe vasomotor symptoms at base line, E+P improved vasomotor symptoms and resulted in a small benefit in terms of sleep disturbance, but no benefit in terms of the other QOL outcomes.QOL = quality of life; NS = not significant.1Anderson GL, et al.

9 WHI Updated Results Summary: Stroke 2004 Patient ManagementWHI Updated Results Summary: StrokeAfter 5 years, the risk of stroke was 1.8% for E+P, 1.3% for placebo (HR, 1.31; 95% CI, 1.02–1.68)Attributable risk of 0.5% is <0.1% per yearAttributable risk of E+P for stroke increases with ageage 50–59 years is 0.04% per yearage 70–79 years is 0.13% per yearWassertheil-Smoller et al1 assessed the effect of E+P on stroke.One hundred fifty-one patients (1.8%) in the E+P and 107 (1.3%) in the placebo groups had strokes. Overall, 79.8% of strokes were ischemic. For combined ischemic and hemorrhagic strokes, the intention-to-treat HR for E+P vs placebo was 1.31 (95% CI, 1.02–1.68); with adjustment for adherence, the HR was 1.50 (95% CI, 1.08–2.08).For ischemic stroke, HR = 1.44 (95% CI, 1.09–1.90)For hemorrhagic stroke, HR = 0.82 (95% CI, 0.43–1.56)E+P increases the risk of ischemic stroke in generally healthy postmenopausal women. Excess risk for all strokes attributed to E+P appeared to be present in all subgroups of women examined.Framingham risk scores reflect the probability of stroke with in 10 years for women age 55–84 years, based on use of antihypertensive medications, as well as systolic blood pressure, age, diabetes mellitus, cigarette smoking, prior cardiovascular disease, atrial fibrillation, and left ventricular hypertrophy by electrocardiogram.2Two thirds of the women enrolled in the WHI were in the Framingham medium-to-high risk for stroke category; 50% were smokers and 35% were hypertensive.1Wassertheil-Smoller S, et al.

10 WHI Study Considerations 2004 Patient ManagementWHIStudy ConsiderationsThere were relatively high rates of discontinuation in the conjugated equine estrogens (CEE)/ medroxyprogesterone acetate (MPA) group (42%) and crossover to active treatment in the placebo group (10.7%)WHI did not evaluate symptom relief, and therefore symptom relief was not included in the global indexResults do not necessarily relate to lower dosages of these drugs or other formulations or routes of administrationThe results of the WHI are important and will have a significant effect on the way HT is prescribed in the future. However, the study does have limitations.For example, both the rate of discontinuation in the E+P group and the rate of crossover to E+P from the placebo group were higher than expected. The lack of adherence and increased number of women who “dropped in” to the E+P group from the placebo group may have changed the observed treatment effects.The fact the trial was stopped early decreases the precision of estimates of long-term treatment effects—a longer treatment may have shown a greater reduction in the risk of fractures and colon cancer or a greater increase in the risk of other diseases.In addition, the WHI did not evaluate the role of HT in relieving menopausal symptoms, the most common reason women initiate therapy. Therefore, the benefit of HT in relieving menopausal symptoms was not included in the global index.Finally, the results may not relate to lower dosages, other formulations, or other routes of administration of HT.Writing Group for the Women’s Health Initiative Investigators.

JAMA. 2003;290:This slide provides the values for the HRs, CIs, and attributable risks from the WHI. Overall HRs for the major outcomes for CEE/MPA compared with placebo are shown in the black box. For each HR, the CIs that reached statistical significance (ie, those that did not include 1.0) are highlighted in yellow.Summary of findings:Only the increased risk for VTE and PE were statistically significant for both the nCI and aCI. (Note: Publication of the centrally adjudicated results for total fracture and probable dementia did not include an aCI. The nCI for total fracture and probable dementia were statistically significant.)Neither the nCI nor the aCI for CHD were statistically significant.The increased risk for breast cancer and stroke were statistically significant for the nCI, but not the aCIThe decreased risk for colorectal cancer was statistically significant for both the nCI and aCI; the decreased risk for hip fracture was statistically significant for the nCI, but not the aCIWith the exception of total fractures, the absolute excess risk or benefit attributable to CEE/MPA was low. The WHI findings predict that over 1 year, 10,000 women taking CEE/MPA compared with placebo might be expected to experience 6 more CHD events, 8 more invasive breast cancers, 7 more strokes, 18 more VTEs, 8 more PEs, 6 fewer colorectal cancers, 5 fewer hip fractures, and 47 fewer total fractures.In a subgroup of women age 65 years and older at baseline, 23 more cases of probable dementia would be predicted by these findings.These risk estimates apply only to the population of women represented by the subjects who participated in the WHI, that is, older women initiating HT for the first time who have significant risk factors for chronic disease, such as overweight/obesity and history of smoking.Manson JE, et al.

14 Interpretation of the WHI Data 2004 Patient ManagementInterpretation of the WHI DataMajority of women initiate HT to alleviate menopausal symptoms175% of HT users initiate therapy within 5 years of menopauseIn a 1999 national survey (n = 9400; age 40 years), 24% used HT, 3% E+P for 5 years, 10% used ET for 5 years2Results should not be extrapolated to symptomatic early menopausal or prematurely menopausal women using HT for symptom relief3Average age at screening, 63 yearsOnly 4% of WHI participants had moderate to severe vasomotor symptomsSeveral considerations should be taken into account in interpreting the WHI findings.The average age of WHI participants at initial screening was ~63 years old.1 The average age that nonhysterectomized women initiate HT is 51 years.2Only 4% of WHI participants had moderate to severe vasomotor symptoms.When the study was stopped in 2002, two-thirds of the participants were 68 years or older.42% of the women in the CEE/MPA group and 38% of the women in the placebo group discontinued study medication at some time during the trial. The high rate of discontinuation in the CEE/MPA group and the crossover of women from placebo to CEE/MPA (10.7%) may have influenced the study results.Pre-WHI results: In a 1999 national survey (n = 9,400; age 40 years), 24% of women were hormone users; however, only 3% of women used E+P for 5 or more years, and only 10% used E alone for 5 or more years.3The NAMS Position Statement4 recommends that data from studies such as HERS and WHI should be extrapolated only with caution to women <50 years of age who initiate HT, and should not be extrapolated to women experiencing premature menopause (<40 years of age) and initiating HT at that time.1Writing Group for the Women's Health Initiative Investigators.

15 2004 Patient ManagementPost-WHI Survey1000 high-compliance Kaiser Permanente patients were mailed a letter explaining the WHI study findings and recommendations about continuing HT670 women agreed to complete an interview94.5% considered stopping HT56% of women attempted to discontinue HT44% chose to continue therapy; of those women25.7% for relief of vasomotor symptoms19.2% for osteoporosis47.2% for other reasons (ie, mood swings, vaginal dryness, urinary incontinence, and depression)Ettinger et al examined the degree that women who were using postmenopausal HT prior to the publication of the WHI results had been informed of the findings. They also analyzed how knowledge of these findings was associated with women’s decisions to continue or discontinue HT.A telephone survey of 670 female members of a large health maintenance organization, aged 50 to 69 years, who had regularly used HT from July 1, 2001, through June 30, 2002 was performed.Selection was limited to women who demonstrated high compliance, which was defined as filling three prescriptions for 100 pills of estrogen from July 1, 2001, through June 30, Of this population, 39% used E alone, 61% used E+P. Most were long-term users (median duration of use, 9 years).Most women (93%) reported hearing about the new findings; however, only 57% considered the quality of this information to be good, regardless of its source: mass media (21%), the health plan (32%), or a health care practitioner (34%).Ettinger B, et al.

16 Statement on HT From ACOG 2004 Patient ManagementStatement on HT From ACOGWomen who have been taking HT for a number of years should not panic, but discuss their individual situation with their physicianWith respect to women’s short-term use of HT for relief of menopausal symptoms, it may be reasonable for women to continue use for this purpose because the benefits are likely to outweigh the risksFor short-term use of HT for relief of menopausal symptoms, ACOG continues to recommend that this be a personal, individualized decision, made after consultations between a woman and her physician—taking into account a woman’s individual benefits and risks from such useIn response to the WHI report, the American College of Obstetricians and Gynecologists (ACOG) issued a statement on the implications of the findings for clinicians and their patients.Points emphasized in the ACOG statementThe preliminary data reported from WHI represent an increased breast cancer risk of less than 1% per year for an individual woman.The WHI did not focus on short-term risks and benefits of HT. It may be reasonable for women to continue short-term use of combined HT for relief of vasomotor symptoms, as the benefits from short-term therapy are likely to outweigh the risks.ACOG continues to recommend that the decision to use HT should be a personal and individualized one. A woman’s individual benefits and risks should be addressed in consultation with a physician.American College of Obstetricians and Gynecologists (ACOG).

17 2003 NAMS Position Statement on HT 2004 Patient Management2003 NAMS Position Statement on HTPrimary indication for systemic HT is the treatment of moderate-to-severe menopausal symptomsLocal estrogen recommended for moderate-to-severe vulvar and vaginal atrophyPrimary indication for progestogenEndometrial protectionHT should not be used for 1° or 2° prevention of CHD or strokeWHI results cannot be extrapolated toSymptomatic perimenopausal womenPremature menopauseHT should be used at the lowest effective dose for the shortest duration neededThe termination of the E+P trial of the WHI study in July 2002 led the NAMS Advisory Panel to prepare a report on postmenopausal HT. Almost a year later, a second report was prepared by this group, presenting clinical recommendations for use of HT in peri- and postmenopausal women.Some of the NAMS recommendations include the following.Treatment of moderate and severe menopausal symptoms (ie, vasomotor symptoms, sleep disruption from vasomotor symptoms) remains the primary indication for systemic estrogen-only therapy and combined E+P. Every systemic HT product is government approved for this indication.The primary menopause-related indication for progestogen use is endometrial protection from unopposed E. For all women with an intact uterus who are using estrogen, clinicians are advised to prescribe adequate progestogen, in either a continuous-combined E+P or continuous-sequential E+P regimen. Women without a uterus should not be prescribed a progestogen.Some women with an intact uterus who choose E+P may experience undesirable side effects from the progestogen component; however, there is insufficient evidence regarding long-term endometrial safety to recommend use of long-cycle progestogen (ie, progestogen every 3-6 months for days), a progestin-containing intrauterine device, or low-dose estrogen without progestogen as an alternative to standard E+P regimens. If utilizing any of these approaches, closer surveillance of the endometrium is recommended, pending more definitive research.North American Menopause Society (NAMS).

19 Summary of NIH Recommendations 2004 Patient ManagementSummary of NIH RecommendationsWhile short-term use was not studied in the WHI, women taking HT for relief of menopausal symptoms may reap more benefits than risksWomen should keep up with their regular schedule of mammograms and breast self-examinationsHT should not be continued or started to prevent heart disease; women should consult their doctor about other methods of CVD preventionFor osteoporosis prevention, women should consult their doctor and weigh the benefits against their personal risks; alternate treatments are available to prevent osteoporosis and fracturesWith the publication of the WHI results, the National Institutes of Health (NIH) also released a new set of recommendations for the use of HT.First, the NIH recommended that HT should not be continued or initiated to prevent heart disease. Instead, women should consult their doctor about other methods of CVD prevention, including lifestyle changes and medications that lower cholesterol and/or blood pressure.Although this study confirmed that HT provides significant protection from hip, vertebral, and overall fracture, women should consult their doctor and weigh the benefits of HT against their personal risk for heart attack, stroke, venous thromboembolism, and breast cancer.National Institutes of Health (NIH).

21 Barriers to Appropriate Use of HT 2004 Patient ManagementBarriers to Appropriate Use of HTConcerns about the long-term safety of HTHT-related vaginal bleedingInadequate counseling on the risks and benefitsMany women who are appropriate candidates for postmenopausal HT do not initiate therapy because of their concerns about the long-term safety of HT.1Among women who choose to initiate therapy, many discontinue HT because of vaginal bleeding.2To ensure that the treatment goals of women considering or initiating postmenopausal HT are met, health care providers should address these concerns when counseling their patients. Despite prolific media coverage of the WHI, for example, physicians should help their patients make informed decisions. The Health Employer Data Information System menopause counseling measure, instituted in 2000, is aimed at improving women’s knowledge about HT through better counseling.3Ettinger et al4 reported that most women (93%) reported hearing about the WHI findings; however, only 57% considered the quality of this information to be good, regardless of its source: mass media (21%), the health plan (32%), or a health care practitioner (34%).1Newton KM, et al.

However, many American women do not understand their true risk of these diseases. In fact, the problems that women perceive to be their greatest health risks are generally different than their actual causes of death.In a telephone survey of 1,000 US women, approximately 34% of respondents identified breast cancer as the greatest health problem confronting women, while 61% identified all cancers.

24 Absolute Risk of Breast Cancer in the General Population 2004 Patient ManagementAbsolute Risk of Breast Cancer in the General PopulationEach 50-year-old woman has approximately a 2.8% chance of developing breast cancer by age 60 yearsThis translates to an absolute risk of 2.8 per 100 womenAll Women Aged 50 Years in the General Population— Risk for Breast Cancer by Age 60 YearsIn 100 women, 2.8 are at riskTo address patients’ confusion regarding breast cancer risk, it may be helpful to discuss a woman’s absolute risk of breast cancer, with or without HT, in addition to discussing relative and attributable risk.RR is the ratio of the risk of disease among those exposed to a risk factor to the risk among those who were not exposed and is independent of the overall incidence of disease in the population.Absolute risk is the overall incidence of a disease in a given population.Attributable risk refers to the excess risk of disease in patients exposed to a potential risk factor, above and beyond the risk expected in patients not exposed to the potential risk factor.Absolute risk of breast cancer is shown in this slide. According to the American Cancer Society, a 50-year-old woman has a 2.8% chance of developing breast cancer before she turns 60 years of age. Therefore, among 100 women, 2.8 are at risk for breast cancer.American Cancer Society. Breast Cancer Facts and Figures 2001–2002. Available at: downloads/STT/BrCaFF2001.pdf.American Cancer Society.

25 Absolute Risk of Breast Cancer After 5 Years of HT 2004 Patient ManagementAbsolute Risk of Breast Cancer After 5 Years of HTWHI results indicate a hazard risk for breast cancer of (P < .001) after 5 years of HT use (a 24% increase in risk)This translates into an absolute risk of 3.5 per 100 usersRisk of Breast Cancer by Age 60 Years After 5 Years of HT Use (Assuming a 24% Increase in Risk)3.5 of 100 women who are HT users are at risk (<1 additional woman over baseline risk)In the WHI, Chlebowski et al1 reported that 5.6 years of HT use was associated with an HR for breast cancer of Therefore, women receiving HT experienced an 24% increase in the risk of breast cancer compared with women using placebo. As noted in the previous slide, the absolute risk of breast cancer by age 60 years among 50-year-old women is 2.8 cases per 100 women; a 24% increase in this risk translates into an absolute risk of 3.5 cases per 100 women who use HT for approximately 5 years.1,2A discussion of the attributable risk associated with HT also may help patients put breast cancer risk with HT into perspective. The attributable risk of breast cancer in HT users, or the excess risk of breast cancer in HT users versus nonusers, is the difference between the incidence rates of HT users compared with nonusers. Therefore, the attributable risk of breast cancer in women who are 50 years of age and use HT for 5 years is 0.7 per 100 women.American Cancer Society. Breast Cancer Facts and Figures 2001–2002.

27 Addressing Patients’ Breast Health Concerns 2004 Patient ManagementAddressing Patients’ Breast Health ConcernsThe WHI reported a small, increased risk of invasive breast cancer with an average of 5.6 years of E+P useMost observational studies do not show an increased risk of breast cancer with HT use; some suggest a small increased risk with long-term HT useRisk estimates from prospective, randomized trials and observational studies are similarIn the WHI, breast cancers in women assigned to E+P were somewhat larger and more likely to involve regional lymph nodes; other studies show that HT users have less aggressive, smaller tumorsIn summary, the WHI indicated that use of E+P is associated with a small but statistically significant increased risk of invasive breast cancer. Numerous other studies show a similarly small increased risk or no increased risk with use of E+P. Longer durations of use appear to be associated with increasing risk.The E-only arm of the WHI was recently stopped approximately one year prior to its planned completion date. Preliminary analyses indicate no increased risk of breast cancer with a mean of 7 years of use.In the WHI, breast cancers diagnosed in women assigned to receive E+P were somewhat larger and more likely to involve regional lymph nodes. Most other studies show that HT users are more likely to be diagnosed with smaller, lower stage, less aggressive tumors. Additional research is needed to understand these discrepant findings.Writing Group for the Women’s Health Initiative Investigators. JAMA. 2002;288:Bush TL, et al.

28 Addressing Patients’ Breast Health Concerns continued 2004 Patient ManagementAddressing Patients’ Breast Health Concerns continuedPositive family history of breast cancer is not a contraindication for HTIn observational studies, breast cancer survival rates are better in HT usersMillion Women Study reported greater risk of fatal breast cancer among HT users, however breast cancer survival rates were equivalent among HT users and nonusersIn breast cancer survivors, HT use has not been shown to worsen mortality or recurrenceResearch on breast cancer risk and HT use also indicates that a positive family history of breast cancer is not a contraindication for HT.Numerous studies show that total mortality rates are lower among women who use HT.A notable exception to this is the Million Women Study; however, if breast cancer mortality rate is calculated in the same manner as it is calculated in most other studies (ie, breast cancer deaths/breast cancer cases), the mortality rate among current HT users in the Million Women Study was lower than the rate observed in never-users.The relatively short follow-up time for the WHI prevented determination of mortality due to breast cancer; however, all-cause mortality was slightly lower (and not statistically different) for HT users (HR for total mortality 0.98; nCI, 0.82–1.18 and aCI, 0.70–1.37).Several hypotheses for why breast cancer patients who are taking HT may have a reduced risk of dying from breast cancer areDetection/surveillance biasSelection biasTumors diagnosed in HT users are generally smaller, lower grade, and less aggressive than those in nonusersLastly, among women treated for breast cancer, HT use has not been shown to worsen recurrence or mortality rates.Sellers TA, et al.

29 HT-Related Breakthrough Bleeding 2004 Patient ManagementHT-Related Breakthrough BleedingAll available continuous-combined E+P regimens are associated with breakthrough bleedingLess breakthrough bleeding with lower dosesDefinitions and indices used to report bleeding patterns varyMost postmenopausal women will experience amenorrhea within 1 year of initiating therapyWomen who are postmenopausal >3 years may experience less bleeding than recently menopausal womenManaging patient expectations about breakthrough bleeding is criticalContinuous-combined regimens of E+P eliminate the cyclic bleeding that occurs with sequential regimens. But continuous regimens are associated with breakthrough bleeding, which can be perceived by women as bothersome. Almost all such regimens are associated with breakthrough bleeding; many, although not all, women will experience this phenomenon within the initial months of therapy.1-4Most women will achieve amenorrhea from continuous-combined regimens within 1 year of starting E+P. Unless a women is clearly aware of this statistic, however, the unpredictability and inconvenience of breakthrough bleeding may result in early discontinuation. Women who are more than 3 years postmenopausal may experience less bleeding, but this does not suggest that delaying therapy until this time is warranted. Rather, it emphasizes the critical importance of counseling in the early menopausal stage.Early postmenopausal women who cannot tolerate irregular breakthrough bleeding may benefit from cyclic E+P, a regimen that provides predictable withdrawal bleeding. If a newly menopausal woman desires amenorrhea, she can be switched to continuous E+P after 1 year.Archer DF, Pickar JH. Climacteric. 2002;5:45-69; Archer DF, et al.

Results from the CEE/MPA groups and the placebo group in the efficacy-evaluable population are shown on this slide.The efficacy-evaluable population included patients who recorded taking study medication and completed 13 cycles, completed all thirteen 28-day diary cards without missing any bleeding data, and did not miss ≥3 consecutive days or ≥5 discontinuous days of taking or recording study medication during any treatment cycle.Episodes of vaginal bleeding or spotting were recorded in the patients’ daily diary cards. The following definitions were used to characterize bleeding episodes in the study.Bleeding: vaginal bleeding requiring sanitary protectionSpotting: vaginal bleeding not requiring sanitary protectionNo bleeding: absence of vaginal bleeding with or without spottingAmenorrhea: absence of vaginal bleeding or spottingBleeding data were analyzed in a cumulative fashion and by individual cycles. In the cumulative analysis, cumulative amenorrhea was defined as the percentage of patients experiencing consecutive cycles of amenorrhea through cycle 13.Throughout the course of the study, the rates for cumulative amenorrhea were greater in the lower-dose CEE/MPA groups than in the CEE 0.625/MPA 2.5 group. The difference between these groups was most apparent during the earlier cycles.Women in all of the CEE/MPA groups exhibited significantly lower rates of cumulative amenorrhea than those taking placebo (P < .05) for each cycle range analyzed.EE = Efficacy-evaluable population included women who recorded taking study medication and completed all 13 cycles without missing data on bleeding.Archer DF, et al.

35 Individualizing Patient Management With HT Type of estrogen/progestinDose of estrogen/progestinType of regimen (cyclic vs continuous)Metabolic profiles of hormone combinationsFlexibility of treatmentExperience with therapyPatient satisfaction with therapyThere are a variety of factors to consider when administering HT. For example, the type of estrogen and progestin, the type of HT regimen, and the dose of HT may all affect patient adherence.Metabolic factors may also be important in choosing an HT regimen. Since each estrogen/progestin combination has a unique lipid profile, health care practitioners may also want to consider the metabolic profiles of available HT formulations when initiating HT in a particular patient.Health care practitioners may also prefer to administer therapies available in a variety of different doses and regimens, making it easier to tailor therapy to an individual patient. Their experience with a particular therapy and their patients’ satisfaction with that therapy should also be considered.

These compounds can generally be classified as natural, native/synthetic, or synthetic.Natural estrogens, such as CEE, can be formulated as a drug with minimal processing and no chemical modification.Native/synthetic estrogens, such as 17-estradiol, exist in nature but must be synthesized from compounds present in plants. Synthesizing 17-estradiol and other steroid hormones from the Mexican yam or the soy bean requires several chemical steps.Although the steroid hormones synthesized from these plants are chemically the same as those produced by the human body, there is no scientific evidence to date that indicates that consumption (either ingestion or as topical creams) of the Mexican yam, sweet yam, or soy bean leads to the formation of 17-estradiol, estrone, or other steroids in the human body. The human body lacks the necessary enzymes to convert plant sterols into active steroid hormones.Finally, synthetic steroids are produced by chemists and are not found in nature.Many patients believe that native/synthetic estrogens are safer and are equally or more effective than standard estrogens; however, estrogen receptors (ERs) cannot distinguish between chemically identical estrogens from different sources. Moreover, few studies have compared the safety and efficacy of natural, native/synthetic, and synthetic estrogens.

However, the only natural progestin is progesterone, which can be found in humans and certain animals, but not in plants. Synthetic progestins are defined as progestins that are synthesized chemically.Synthesized progestins can be categorized into two groups: those that are structurally related to progesterone, and those that are structurally related to testosterone. This classification scheme does not imply the source of the steroid precursor.Progestins that are structurally related to progesterone can be subdivided into those with (pregnane derivatives) and without (19-norpregnane derivatives) a methyl group at carbon 10. Pregnane derivatives include MPA and megestrol acetate, while 19-norpregnane derivatives include trimegestone and demegestone.Both pregnane derivatives and 19-norpregnane derivatives can also be classified as to whether they are acetylated or nonacetylated. All pregnane-derived progestins are acetylated except dydrogesterone, and all 19-norpregnane derivatives are nonacetylated besides nomegestrol acetate.Progestins structurally related to testosterone are either ethinylated (those that contain an ethinyl group at carbon 17) or nonethinylated. Ethinylated progestins include norethindrone acetate and levonorgestrel. Dienogest and drospirenone are the only nonethinylated progestins.Ethinylated progestins can be further divided into those that have an estrane structure, such as norethindrone and tibolone, and those with a 13-ethylgonane structure, such as norgestimate.Stanczyk FZ.

Although progestins with minimal androgenic effects are preferable, hormone replacement with an androgen may have a role in treating a select, adequately estrogenized population of postmenopausal women experiencing sexual dysfunction.The metabolic effects of an E+P formulation depend on the type and dose of the estrogen and progestin, and the formulation’s route of administration. A summary of the metabolic effects of various oral E+P formulations is shown on this slide.

41 Endometrial Response to Sequential Versus Continuous E+P 2004 Patient ManagementEndometrial Response to Sequential Versus Continuous E+POpen-label, prospective study, 1312 women taking sequential E+P (with 10 days of progestin) and 921 not using any HT were given continuous E+P for 9 monthsAt baseline, sequential E+P was associated with complex hyperplasia (5.3%) and atypical hyperplasia (0.7%)Continuous-combined E+PWas not associated with an increased risk of hyperplasiaConverted the endometrium to normal in those with complex hyperplasia arising during sequential E+PSequential therapy was associated with a higher risk of endometrial hyperplasia than continuous therapyIn an open-label prospective study conducted in the UK, Sturdee and colleagues enrolled 1312 women (mean age, 53 years) who were using, at baseline, sequential E+P with at least 10 days of progestin per cycle. The most commonly used regimen included 12 days of progestin per cycle.The study also enrolled 921 women (mean age, 54 years) who were not using any HT at baseline. Both groups of women were given continuous 2 mg 17-estradiol and 1 mg norethisterone acetate for 9 months.At baseline, complex endometrial hyperplasia was observed in 59 women (5.3%) initially receiving sequential E+P. Atypical hyperplasia was seen in 8 women (0.7%) receiving sequential E+P.After 9 months, no cases of hyperplasia were observed in the 1196 biopsies of women who completed the study, including in 38 of the 59 women with complex hyperplasia at baseline who completed the study. Therefore, continuous E+P converted the endometrium to normal in women with hyperplasia who had been using sequential E+P.In the women who did not complete the study (n = 21), the hyperplasia reverted to normal in 12 women and persisted in 4. Of these 4, one never took continuous E+P, and the other 3 received it for 3 months or less. Of the remaining 5 women, 1 was not treated with continuous E+P and had no final biopsy, 1 was lost to follow-up, and 3 refused a final biopsy.Sturdee DW, et al.

Participants recorded the number and severity of hot flushes on daily diary cards throughout the screening and study periods.This graph depicts mean number of hot flushes over a 12-week period for women given unopposed CEE (0.625, 0.45, or 0.3 mg/d), CEE with MPA (0.625/2.5, 0.45/2.5, 0.45/1.5, or 0.3/1.5 mg/d), or placebo.Data for unopposed CEE groups are shown on the left, and CEE/MPA data are shown on the right.Within one week of initiating therapy, all treatment groups (including placebo) experienced a significant reduction in number of hot flushes compared with baseline, except for the CEE 0.3/MPA 1.5 group, which decreased from baseline (P < .001) by the end of the second week. By the third week, all CEE and CEE/MPA treatment groups exhibited a significant (P < .001) reduction in mean daily number of hot flushes compared with the placebo group. These differences were maintained throughout the 1-year trial.Thus, all of the doses of CEE alone or CEE/MPA examined in this study provided significant symptom relief within the first few weeks of use.The reduction in number of hot flushes was comparable in all CEE/MPA groups.The results also suggest that the addition of MPA to lower doses of CEE may enhance the relief of vasomotor symptoms seen with CEE alone.*Adjusted for baseline.Mean hot flushes at baseline = 12.3 (range 11.3–13.8).

Moderate hot flushes were defined as warm sensations with sweating that did not disrupt activity, and severe hot flushes were defined as hot sensations with sweating that did disrupt activity.Daily hot flush severity scores were calculated using the following equation: [(# of mild flushes 1) + (# of moderate hot flushes 2) + (# of severe hot flushes 3)] ÷ total of # hot flushes on that day.Treatment with all active study regimens resulted in significant decreases from baseline (P < .001) by the second week of treatment. Significant differences from baseline were observed in the placebo group by week 3 (P < .05).By the third week of treatment, all CEE and CEE/MPA groups reported significantly lower mean daily severity of hot flushes compared with placebo (P < .05).The benefits of CEE and CEE/MPA in reducing hot flush severity were maintained throughout the course of the study.Hot flush severity: 1 = mild, 2 = moderate, 3 = severe.

60 Women's HOPE Study Changes in Spine BMD CEE CEE/MPA 2004 Patient ManagementWomen's HOPE StudyChanges in Spine BMDCEECEE/MPAThere is evidence that doses of HT lower than those most commonly prescribed may be effective in preventing bone loss in older women1; however, prior to the Women’s HOPE study, the effects of lower doses of HT in early postmenopausal women had not been well documented.The 2-year bone substudy of the Women’s HOPE study (n = 822) evaluated the skeletal effects of lower doses of CEE and CEE/MPA in postmenopausal women who were within 4 years of their last menstrual period.2These graphs include data from the intent-to-treat population, which consisted of all women randomized to treatment who recorded taking at least 1 dose of the study drug and had at least 1 BMD measurement after baseline.After 2 years, women assigned to all of the active treatment groups had significant gains from baseline (P < .001) in spine BMD. These changes were statistically different from those in the placebo group (P < .001). In addition, adding 2.5 mg MPA to mg or 0.45 mg CEE significantly increased spine BMD relative to to the equivalent dose of CEE alone (P < .05).These data demonstrate that lower doses of CEE and CEE/MPA effectively prevent bone loss in the spine in early postmenopausal women.Intent-to-treat population only.

Endometrial biopsies were evaluated at baseline and years 0.5, 1, 1.5, and 2 using a centralized protocol.As shown in the bar chart, no cases of endometrial hyperplasia were seen in the four CEE/MPA groups. For the CEE-alone groups, a dose-related increase in incidence from 3.17% (CEE 0.3 mg) to 27.27% (CEE mg) was seen at 2 years.The number of cases increased from year 1 to year 2, even in the low-dose CEE 0.3 group.Thus, 2 years of treatment with lower doses of CEE/MPA provided endometrial protection comparable to that seen with commonly prescribed doses. These results are especially relevant with recent guidance from the FDA to use the lowest effective dose of HT for the shortest duration needed to achieve treatment goals.Pickar JH, et al.

64 Low-Dose HT: Conclusions 2004 Patient ManagementLow-Dose HT: ConclusionsResearch findings demonstrate that lower doses of estrogen and progestinRelieve vasomotor symptoms and prevent vaginal atrophyAre associated with a reduced incidence of endometrial bleeding, especially in the early months of therapyProvide effective endometrial protectionPrevent early postmenopausal bone lossLower-dose regimens provide clinicians and patients with expanded options for individualizing HTE alone at lower dosages for longer durations may be associated with increased rates of endometrial hyperplasiaRecent studies, including the Women’s HOPE study, indicate that lower-than-standard doses of estrogen and progestin provide benefits that are comparable to those associated with the most commonly prescribed regimens.Lower doses of estrogen and progestin relieve vasomotor symptoms and vaginal atrophy, protect the endometrium, and prevent early postmenopausal bone loss. In addition, lower doses are associated with more favorable bleeding profiles compared to the most commonly prescribed doses.Greater awareness among clinicians and their patients about the potential for fewer side effects, less bleeding, and comparable efficacy with the use of lower doses of estrogen and progestin will benefit many postmenopausal women.Unopposed estrogen at lower dosages for longer durations may be associated with increased rates of endometrial hyperplasia.

In addition, a number of proven therapies are available for the management of common health issues in postmenopausal women.Medications such as bisphosphonates, selective estrogen receptor modulators (SERMs), and calcitonin are available for women at risk for osteoporosis or osteoporotic fracture.In addition, lipid-lowering drugs should be used in dyslipidemic patients.More and more women are turning to alternative therapies to control symptoms of menopause and other ailments; however, there is little evidence regarding the safety and efficacy of many such products.

Similar but attenuated findings were observed for strenuous physical activity at ages 18 years and 50 years. Women who engaged in the equivalent of 1.25 to 2.5 hours per week of brisk walking had an 18% decreased risk of breast cancer (RR, 0.82; 95% CI, 0.68–0.97) compared with inactive women.In a cohort of 25,624 women followed for a median of 13.7 years,2 greater leisure-time activity was associated with a reduced risk of breast cancer, after adjustments for age, body mass index, height, parity, and county of residence (RR, 0.63; 95% CI, 0.42–0.95), among women who exercised regularly, as compared with sedentary women (P for trend = .04).Li and colleagues3 found that ever-use of alcohol over the past 20 years was associated with a 1.3-fold (95% CI, 1.0 –1.5) increased risk of breast cancer, although this increase was primarily limited to women who consumed >30.0 g/day of alcohol (OR, 1.7; 95% CI, 1.1–2.6). These results are consistent with there being an underlying hormonal basis for the known association between alcohol use and breast cancer.Obesity is also associated with breast cancer risk.4,5 Huang and colleagues4 found a strong positive association between weight gain and breast cancer incidence in never-users of hormones. Morimoto and colleagues5 confirmed previously reported findings that generalized obesity is an important risk factor for postmenopausal breast cancer, but only among women who have never used HT. Lifetime weight gain is also a strong predictor of breast cancer.Reynolds et al6 found that, irrespective of whether they included passive smokers in the reference category, the incidence of breast cancer among current smokers was higher than that among never smokers (HR, 1.32; 95% CI, 1.10–1.57 relative to all never smokers; HR, 1.25, 95% CI, 1.02–1.53 relative to only those never smokers who were unexposed to household passive smoking). This study provides evidence that active smoking may play a role in breast cancer.1McTiernan A, et al. JAMA. 2003;290:1331-6; 2Thune I, et al. N Engl J Med. 1997;336: ;3Li CI, et al.

73 Non-HT Alternatives for Vasomotor Symptoms 2004 Patient ManagementNon-HT Alternatives for Vasomotor SymptomsLifestyle changes (limited effectiveness)Cooling body core temperatureExerciseAvoiding hot and spicy foodsPace respirationsRelaxing activitiesA number of lifestyle and social factors may influence hot flush frequency:Warm ambient air temperatures increase a woman’s core body temperature and make her more likely to reach the sweating threshold.Less physical activity increases the relative risk of hot flushes; daily exercise is associated with an overall decreased incidence.Anecdotally, spicy foods have been reported to trigger hot flushes, though there is no clinical evidence to support this relationship.Other lifestyle factors that affect vasomotor symptoms:Cigarette smoking (past and current) increases the relative risk of hot flushes, perhaps because of its effect on estrogen metabolism.North American Menopause Society.

74 Non-Prescription Remedies 2004 Patient ManagementNon-Prescription RemediesSome alternative therapies may provide relief of mild vasomotor symptoms for some womenPhytoestrogens/isoflavonesDietary or supplements (soy-derived)Red cloverBlack cohoshVitamin E – not clinically significantStudies show no effect compared with placebo forDong quaiGinsengEvening primrose oilSome alternative therapies may provide relief of mild vasomotor symptoms for some women.Among nonprescription remedies, clinical trial results are insufficient to either support or refute efficacy for soy foods and isoflavone supplements (from either soy or red clover), black cohosh, or vitamin E; however, no serious side effects have been associated with short-term use of these therapies. Single clinical trials have found no benefit for dong quai, evening primrose oil, ginseng, a Chinese herbal mixture, acupuncture, or magnet therapy.1Kronenberg and Fugh-Berman2 reported that soy seems to have modest benefit for hot flushes, but studies are not conclusive, and isoflavone preparations seem to be even less effective than soy foods. Black cohosh may be effective for menopausal symptoms, especially hot flushes, but the lack of adequate long-term safety data precludes recommending long-term use. Black cohosh and foods that contain phytoestrogens may provide relief of menopausal symptoms, but clinical trials do not support the use of other herbs or CAM therapies (eg, dong quai, evening primrose oil, a Chinese herb mixture, vitamin E, and acupuncture).Huntley and Ernst3 concluded that there is no convincing evidence for any herbal medical product (eg, black cohosh, red clover) in the treatment of menopausal symptoms, due in part to poor methodology of the trials.North American Menopause Society.

75 Alternative Non-Prescription Therapies: Concerns 2004 Patient ManagementAlternative Non-Prescription Therapies: ConcernsAggressive marketing generates inquiries and useSide effects and drug interactions are not well known but clearly occurLack long-term safety and efficacy dataWhen possible, providers should record use and amountsLong-term, adequately powered, randomized, placebo-controlled, clinical trials with defined entry criteria are neededFDA efficacy trials require a minimum of 7 to 8 per day or 50 to 60 per week moderate to severe hot flushesThe increasing interest in alternative therapies is created by aggressive marketing, thus, patients, and not healthcare providers, are often the initiators and decision-makers about these options. Because of this patient-driven aspect, it is critical that practitioners acknowledge their use and help patients make informed decisions when possible. It is not sufficient to tell patients that such alternatives are “not recommended.”Patients need to know that side effects can occur, and that limited research is only beginning to yield data on whether alternative agents are safe and effective.Ang-Lee et al1 reported side effects associated with alternative therapies during the perioperative period:Direct effects: bleeding from garlic, ginkgo, and ginseng; cardiovascular instability from ephedra; and hypoglycemia from ginseng.Pharmacodynamic herb-drug interactions: potentiation of the sedative effect of anesthetics by kava and valerian.Pharmacokinetic herb-drug interactions: increased metabolism of many drugs used in the perioperative period by St John's wort.Since the safety of alternative therapies in patients at risk for DVT, breast or endometrial cancer, stroke, or hypercoagulation, or who have a history of coronary artery disease is unknown, the use of these products in these populations should be carefully monitored.For moderate to severe hot flushes, the FDA stipulates that a woman enrolled in clinical trials to establish efficacy must have 7-8 hot flushes per day or per week; efficacy studies of non-HT remedies have enrolled women with lower rates of hot flushes. Most studies are of short duration, and small, short-term, randomized trials can be confounded by placebo effect.21Ang-Lee MK. JAMA. 2001;286:2North American Menopause Society.

76 Phytoestrogens Nonsteroidal plant-derived compounds that bind to ERs 2004 Patient ManagementPhytoestrogensNonsteroidal plant-derived compounds that bind to ERsSome bind weakly to ERMany bind strongly to ERbThree main classesIsoflavones (genistein and daidzein): soybeans, soy products, lentils, chickpeas, red cloverLignans (enterodiol and enterolactone): wide variety of fruits, vegetables, and cereals; concentrated in flaxseedCoumestans (coumestrol): bean sprouts, fodder crops (alfalfa)Phytoestrogens are nonsteroidal compounds derived from plants that are structurally similar to estradiol.1 They exhibit both estrogenic activity and antiestrogenic activity.2 In the past, they have been considered “weak” estrogens because their binding affinity for the ER was considerably less than that of estradiol. However, some phytoestrogens have a relatively high binding affinity for ER compared with estradiol.3There are three main classes of phytoestrogens: isoflavones, lignans, and coumestans.Isoflavones, which include genistein and daidzein, are found in soy beans, soy products, lentils, chickpeas, and red clover. Genistein and daidzein are believed to be responsible for the estrogen-like effects of soy.Lignans, which include enterodiol and enterolactone, are found in many fruits, vegetables, and cereals.Coumestans can be isolated in high concentrations from bean sprouts and fodder crops, such as alfalfa.ER = estrogen receptor.Scheiber MD, Rebar RW.

Two common sources of isoflavones are soy and red clover.Randomized, controlled clinical trials have shown that, in general, hot flushes are only slightly reduced in women who consume soy-derived isoflavones when compared with controls.Comparing results from studies is difficult because different products and amounts of isoflavones have been evaluated; symptom indices used to measure efficacy also differed.North American Menopause Society.

This study primarily demonstrated that black cohosh does not reduce hot flushes in breast cancer survivors on tamoxifen.Thus, clinical trial evidence evaluating the efficacy of black cohosh suggests a possible weak effect on vasomotor symptoms, but there is not convincing data at present to prove its efficacy above that of placebo. Better-designed, placebo-controlled trials are required.Huntley AL, Ernst E. Menopause. 2003;10:1Warnecke G. Medwelt. 1985;36:871-4; 2Stoll W.

The 33-day study design was as follows:first 10 days, applied either cream A (progesterone) or B (placebo)4-day no-treatment washoutnext 10 days (days 15–24), applied other creamall patients then took oral natural progesterone 100 mg in the morning and 200 mg at night for 5 daysAnalysis of pregnanediol-3-glucuronide (P3G) confirmed that the systemic absorption of progesterone from progesterone is small (median value after 10 days of treatment, 4.2 mmol/L).Wren et al2 studied 27 postmenopausal women (50–65 years of age) who had an intact uterus, amenorrhoea of more than 12 months duration, and concentrations of follicle-stimulating hormone in the postmenopausal range; women were randomly allocated daily either 16 mg (n = 9), 32 mg (n = 8), or 64 mg (n = 10) of micronised progesterone, applied as a cream for 14 days (days 15–28) of each 4-week treatment cycle.Results showed that use of micronised transdermal progesterone for 14 days over 3 cycles, even at concentrations as high as 64 mg/d, did not increase circulating blood progesterone concentrations sufficiently to induce any evidence of a secretory effect in the endometrium.Lewis and colleagues3 studied 24 postmenopausal women who applied creams (placebo, 20 or 40 mg progesterone/g) twice daily for 3 weeks followed by 1 week washout before a further 3-week treatment.There were small increases in plasma progesterone levels and P3G excretion compared with the placebo group; it was concluded that absorption of progesterone from transdermal creams is low.A study by Komesaroff and colleagues5 suggested that short-term treatment with topical wild yam extract in women suffering from menopausal symptoms is free of side-effects, but appears to have little effect on menopausal symptoms, while Leonetti et al6 found a significant improvement in vasomotor symptoms in women treated with progesterone cream (25 of 30 (83%) treatment subjects and 5 of 26 (19%) placebo subjects [P < .001]).1Cooper A, et al.

Both intramuscular and oral forms have demonstrated efficacy.Intramuscular MPA2-4Contraindications of depot MPA (DMPA) are the same as for estrogen; adverse effects include weight gain, irregular uterine bleeding, amenorrhea, and nervousness.Oral MPA5,6 has shown efficacy similar to DMPA in relieving hot flushes; however, oral MPA is associated with less uterine bleeding and has been associated with no adverse effect on BMDMegestrol acetate has also been studied for treating hot flushes. In a randomized, placebo-controlled, double-blind crossover trial,7 97 postmenopausal women with a history of breast cancer received 4 weeks of relatively low doses of megestrol acetate (20 mg twice daily). To be eligible for the study, the patients must have had bothersome hot flushes (defined as hot flushes that occurred 7times per week and were sufficiently severe that the patient desired therapeutic intervention for at least one month).Hot flushes were reduced by about 85% in the megestrol acetate group compared with 21% in the placebo group, a significant between-group difference (P < .001).A follow-up telephone survey of study participants determined that 18 (31%) of 58 women continued to use megestrol acetate for periods 3 years with continued control of hot flushes and a minimum of side effects.8 No definitive data are available regarding the long-term safety of megestrol acetate for treatment of hot flushes in women with breast cancer.Side effects associated with megestrol acetate include withdrawal uterine bleeding, generally occurring 1 to 2 weeks after discontinuation of therapy, increased appetite (approved indications for treating unwanted weight loss [160- to 800-mg/day range]) and, possibly, exacerbation of preexisting diabetes and an increase in thromboembolic events.North American Menopause Society.

Placebo was reported to reduce hot flushes by approximately 25%. The effect of soy was similar to placebo. Clonidine and vitamin E reduced hot flushes slightly more than placebo. However, the improvement in hot flush scores with clonidine was observed in the first week, whereas the benefit with vitamin E was not apparent for several weeks.The antidepressant, venlafaxine, was the most effective of the nonhormonal treatments, reducing hot flush scores by approximately 50% to 60%.NOTE: These data are not from head-to-head trials. In addition, it is likely that patients in these studies may have been taking tamoxifen, which is often associated with increased vasomotor symptoms.WeekNOTE: These data are not from head-to-head trials.Loprinzi CL, et al.

Median weekly hot flush scores were reduced by 55% from baseline during Week 4 of treatment. Venlafaxine appears to represent an efficacious new method to alleviate hot flushes.In 2000, Loprinzi et al undertook a double-blind, placebo-controlled, randomized trial to assess the efficacy of venlafaxine in women with a history of breast cancer or reluctance to take hormonal treatment because of fear of breast cancer (placebo [n = 56] or venlafaxine 37.5 mg/d [n = 56], 75 mg/d [n = 55], or 150 mg/d [n = 54]; 4-week treatment phase).2All venlafaxine treatment started at 37.5 mg daily and gradually increased in the 75 mg and 150 mg groups. 191 patients had evaluable data for the whole study period (50 placebo, 49 venlafaxine 37.5 mg, 43 venlafaxine 75 mg, 49 venlafaxine 150 mg). After week 4 of treatment, median hot flush scores were reduced from baseline by 27% (95% CI 11-34), 37% (26-54), 61% (50-68), and 61% (48-75) in the four groups. Frequencies of some side-effects (mouth dryness, decreased appetite, nausea, and constipation) were significantly higher in the venlafaxine 75 mg and 150 mg groups than in the placebo group. Venlafaxine was shown to be an effective non-hormonal treatment for hot flushes, though the efficacy must be balanced against the drug's side-effects.In 2002, Barton et al conducted an open-label continuation phase study following a double-blind, randomized, placebo-controlled clinical trial that tested three doses of venlafaxine for the control of hot flushes in 102 postmenopausal women.3The reduction in hot flushes previously reported in the randomized study phase was maintained during the open-label study, and toxicity did not appear to increase over time. This study provides evidence that venlafaxine has intermediate term efficacy and good tolerability as treatment for hot flushes.*Decrease of hot flush score. Schober CE, Ansani NT.

86 Nonhormonal Prescription Therapies: Fluoxetine 2004 Patient ManagementNonhormonal Prescription Therapies: FluoxetineRandomized, double-blind, placebo-controlled, 8-week crossover trial (two 4-week periods) to evaluate the efficacy of fluoxetine (20 mg/day) for vasomotor symptomsN = 81 women with a history of breast cancer or perceived high risk of breast cancerCould be on stable does of tamoxifen or raloxifeneAt least 14 hot flushes per week20% improvement compared with placebo (P = .02)Loprinzi et al1 conducted a double-blind, randomized, two-period (4 weeks per period), crossover study to evaluate the efficacy of fluoxetine (20 mg/d) for treating hot flushes in women with a history of breast cancer or a concern regarding their risk for breast cancer with HT use.Eligible patients had to have reported that they averaged 14 hot flushes per week; the FDA standard for entry into clinical trials for vasomotor symptom relief is 60 hot flushes per week.Eighty-one women were randomized and began protocol therapy. By the end of the first treatment period, hot flush scores (frequency average severity) decreased 50% in the fluoxetine arm versus 36% in the placebo arm. Cross-over analysis demonstrated a significant improvement in hot flush score with fluoxetine compared with placebo (P = .02). The results were not adjusted for potential confounding influences, including age and tamoxifen use. Fluoxetine was well tolerated.The authors concluded that fluoxetine administered at a dose of 20 mg/day resulted in a modest improvement in hot flushes.Contraindications to using fluoxetine (which are also the same for paroxetine) include concomitant use of MAOIs or thioridazine, and caution is advised with concomitant administration of warfarin.2Loprinzi CL, et al.

Also, psychotropic drugs must have been discontinued, although patients could be taking tamoxifen, raloxifene, or vitamin E. Participants recorded vasomotor symptoms in daily hot flush diaries.After a 1-week placebo run-in phase, study participants were randomized to receive placebo (n = 56), 12.5 mg/d of paroxetine CR (n = 51) or 25.0 mg/d of paroxetine CR (n = 58) for 6 weeks. Mean reductions in hot flush frequency composite score from baseline to week 6 were statistically significantly greater for those receiving paroxetine CR than for those receiving placebo (from 7.1 to 3.8 for women in the 12.5-mg/d group; from 6.4 to 3.2 for women in the 25-mg/d group; and from 6.6 to 4.8 for women in the placebo group).Mean placebo-adjusted reduction in hot flush composite scores were -4.7 (95% CI, -8.1 to -1.3; P =.007) for the 12.5-mg/d paroxetine group and -3.6 (95% CI, -6.8 to -0.4; P =.03) for the 25.0-mg/d paroxetine group.Contraindications to using paroxetine (which are also the same for fluoxetine) include concomitant use of MAOIs or thioridazine, and caution is advised with concomitant administration of warfarin.2 Adverse effects observed in trials for depression include asthenia, sweating, nausea, decreased appetite, somnolence, insomnia, and dizziness. The recommended initial dose for treating depression is 20 mg/d.Stearns V, et al. JAMA. 2003;289:1Stearns V, et al. JAMA. 2003;289:2North American Menopause Society. Menopause. 2004;11:11-33.

A randomized, double-blind, placebo-controlled trial was conducted in 59 postmenopausal women with 7 hot flushes per day (meets FDA criteria for trials evaluating vasomotor symptom relief) to examine the effects of 900 mg/d of gabapentin (could be increased up to 2700 mg/d) on hot flush frequency after 12 weeks of treatment. Patients could be taking stable doses of raloxifene, clonidine, or other antidepressants. Participants recorded vasomotor symptoms in daily diaries.Although higher doses of gabapentin are commonly used for treatment of seizures or neuropathies (up to 3000–3600 mg/day), doses as low as 100 mg/day are typically used as starting doses for hot flushes, particularly in older women.2After 12 weeks of treatment, the intention-to-treat analysis showed that gabapentin 900 mg/d was associated with a 45% reduction in hot flush frequency and a 54% reduction in hot flush composite score (frequency and severity combined into one score) from baseline, compared with 29% (P = .02) and 31% (P = .01) reductions, respectively, for placebo.Higher, open-label gabapentin dosing (>900 mg/d) was associated with 54% and 67% reductions in hot flush frequency and composite score from baseline, respectively. The most common adverse events in the gabapentin group during the double-blind study were somnolence (6 patients [20.0%]), dizziness (4 patients [13.3%]), and rash with or without peripheral edema (2 patients [6.7%]), none of which occurred in the placebo group.1 Adverse effects previously observed in seizure trials include somnolence, dizziness, ataxia, fatigue, and nystagmus.2Hypersensitivity to the drug is the only contraindication to gabapentin use.2Guttuso T, Jr, et al.

Mean decreases in frequency of hot flushes were greater in the clonidine than in the placebo group after 4 weeks (37% vs 20%) and 8 weeks (38% vs 24%). Patients receiving clonidine were significantly more likely to report difficulty sleeping (P = .02).An earlier, double-blind, crossover trial randomized 110 women receiving tamoxifen (median age = 54) to 4 weeks of transdermal clonidine (equivalent to a daily dose of 0.1 mg) or placebo.2 Clonidine significantly reduced frequency of hot flushes (P < .0001); however, the results were of modest clinical significance and accompanied by significant increases in dry mouth, constipation, drowsiness, and itchiness. In an earlier study,3 4 out of 10 women withdrew because of side effects experienced with clonidine. Another early trial of transdermal clonidine (n = 29) reported significant relief of hot flushes with minimal side effects.41Pandya KJ, et al. Ann Intern Med. 2000;132:2Goldberg RM, et al.

If lifestyle changes prove inadequate, dietary isoflavones or supplements containing black cohosh or vitamin E may be tried; however, data on these non-prescription remedies have been inconclusive. For example, although a statistically significant decrease in hot flushes among breast cancer survivors was noted in one trial of vitamin E, the results were not clinically significant.HT remains the therapy most often prescribed for moderate to severe hot flushes and the only one approved by the FDA. HT should be used for the shortest duration consistent with its likely risks and benefits for each individual woman. NAMS recommends considering the use of low-dose HT, which has been shown to provide similar relief of vasomotor symptoms.The use of progestogen alone may be considered as treatment for vasomotor symptoms provided that the benefit/risk ratio is acceptable to the individual woman. The contraceptive, depot-MPA (DMPA), MPA, and megestrol acetate have demonstrated effectiveness in clinical trials and may be useful over the short term provided they are not contraindicated. Progestogens have been linked to an increased risk of breast cancer in some studies.Some prescription antidepressants, such as venlafaxine, paroxetine, and fluoxetine, may decrease hot flushes. Side effects such as nausea and sexual dysfunction should be monitored. Very low doses may be used when initiating therapy to minimize side effects.The anticonvulsant, gabapentin, has also been shown to reduce the frequency of hot flushes compared to placebo. Doses up to 300 mg three times a day may be considered.Adapted from North American Menopause Society. Menopause. 2004;11:11-33.North American Menopause Society. Menopause. 2004;11:11-33.

Endocrine Rev. 2002;23:There are several therapeutic options available for osteoporosis prevention and management.1-9HT and alendronate decrease vertebral and hip fracture rates and increase spinal BMD by between 5% and 8%.1-3 Risedronate also decreases vertebral and hip fracture rates and increases spinal BMD by 4% to 6%.4 HT at lower doses increases BMD by 2% to 3%.5 Fracture data in early postmenopausal women are only available for HT.The major side effect of HT is breakthrough bleeding, which usually disappears within 1 year. Alendronate is associated with upper gastrointestinal symptoms such as esophageal and gastric erosions and ulceration, which can be severe.6 Risedronate is also associated with gastrointestinal symptoms, but to a lesser degree than alendronate.6Raloxifene is associated with more modest increases in BMD and a reduced risk of vertebral fracture; however, it does not appear to significantly reduce the risk of hip fracture.7 Since its major side effect is vasomotor symptoms, raloxifene may not be appropriate for early postmenopausal women.Since the bisphosphonates and SERMs have only been available for a relatively short time (<7 years), their long-term safety is unknown.6 They are also considerably more expensive than HT, which may be an important factor for women whose medications are not covered by insurance.Calcitonin also increases BMD by 1% to 2% and is well tolerated.8 However, it is generally considered to be a weaker antiresorptive therapy than HT or bisphosphonates.6In a large (n = 1637), randomized, placebo-controlled trial,10 20 or 40 g/d of PTH (1-34) was associated with significant decreases in the risk of vertebral and nonvertebral fractures and increases in BMD, with only minor side effects.

94 Counseling Topics for Patients Considering HT 2004 Patient ManagementCounseling Topics for Patients Considering HTReview the risks and benefits of HTDiscuss the probability of early bleeding while receiving continuous-combined E+PReview other potential side effectsProvide information about HT and breast healthEmphasize that HT use does not cause weight gainObtain informed consentCounseling for postmenopausal HT is an ongoing process that requires periodic re-evaluation. There is a mass of information for women to absorb, and each office visit provides an opportunity for repetition as well as the introduction of new information.Women tend to be most interested in the immediate aspects of the process, that is, making the initial decision, coping with side effects, and opting for continuation of therapy. In the initial stages, information about bleeding, weight gain, and breast cancer is probably the most relevant. This needs to be balanced with the risks and benefits of HT overall.The decision to use HT can be presented as a short-term commitment. Patients may find decisions regarding HT less daunting if they realize that the decision to continue therapy will be re-evaluated on a yearly basis.

98 Counseling Women About HT 2004 Patient ManagementCounseling Women About HTDocument reasons for considering HT (eg, use quality-of-life questionnaire)Review annually indications for HTExplain benefits of short-term HT use will often outweigh risksEmphasize that risks attributable to HT in the WHI were lowAnnual re-evaluation of the use of HT should include a discussion of recent scientific information and an assessment of how the patient is responding to therapy. Information from recent and ongoing studies, such as PEPI, HERS, WISDOM (International Study of Long Duration Oestrogen After Menopause), WHI, and recommendations from ACOG and NAMS and will aid in counseling women who are using HT or who are considering it.The recommendations recently issued by ACOG in response to the WHI indicated that the benefits of short-term HT use are likely to outweigh their risks. This statement should be stressed to those women considering short-term HT to relieve their menopausal symptoms.In addition, the Writing Group for the WHI indicated that the absolute excess risk attributable to HT was low, which also could reassure patients taking or considering HT.American College of Obstetricians and Gynecologists.

99 Counseling on Duration of HT Use 2004 Patient ManagementCounseling on Duration of HT UseIndividualized TherapyConsider continuing therapy (possibly lower dose) if initial indication was vasomotor symptomsExcess cardiovascular events occurred in the first 2 years in women (average age, 63 years) in the WHI trialBreast cancer risk was not increased with <5 years of HT use in the WHI trialAfter 5 years, HT was associated with a slight increased risk (<0.1% per year)VTE risk continues for duration of therapy (<0.2% per year)Bone protection is afforded by continuing therapyIt is very important when counseling patients on the length of HT use to individualize the therapy for each woman.If the primary indication for initiating hormone use is menopausal symptoms, consider using the lowest effective dose.Excess cardiovascular events occurred in the first 2 years in women (whose average age was 63 years) and VTE risk continues through the duration of use (<0.2% per year)Breast cancer risk was not increased with <5 years of hormone use, and was only slightly increased (<0.1% per year) after 5 years of use.Continuation of hormone use provides protection from fractures.Writing Group for the Women’s Health Initiative Investigators.
