MODULE 5 Case 2: Troy 13/46 How Do You Interpret the Severity and Bother Associated with Troy’s Symptoms?

MODULE 5 Case 2: Troy 14/46 Interpreting the IPSS and Bother Score IPSS Values Indicate Symptom Severity: Mild score: ≤ 7 Moderate score: 8-19 Severe score: ≥ 20 Troy’s IPSS = 17 (moderate symptoms) Troy’s Bother Score = 4 (mostly dissatisfied) IPSS = International Prostate Symptom Score

MODULE 5 Case 2: Troy 15/46 Discussion  The IPSS revealed a score of 17  This is a score of moderate severity and perhaps explains why Troy has been somewhat reluctant to seek treatment  He scores a 4 on the quality of life question, being mostly dissatisfied with his condition IPSS = International Prostate Symptom Score

MODULE 5 Case 2: Troy 21/46 What Investigations Might You Consider for Troy at this Stage?

MODULE 5 Case 2: Troy 22/46 Lab tests:Urinalysis: no abnormal findings Serum creatinine: 72 μmol/L PSA: 1.8 ng/mL Blood/Glucose: normal Midstream urine for C & S (culture and sensitivity): normal Lab Results PSA = Prostate-Specific Antigen

MODULE 5 Case 2: Troy 23/46 Discussion of Lab Results  Troy appears to have moderate symptoms of BPH  Urinalysis shows no evidence of pyuria or bacteria, ruling out infectious syndromes  The serum creatinine is also normal  Troy’s PSA level is normal BPH = Benign Prostatic Hyperplasia PSA = Prostate-Specific Antigen

MODULE 5 Case 2: Troy 24/46 What is the Most Likely Diagnosis for Troy?

MODULE 5 Case 2: Troy 25/46 Diagnosis  On the basis of the normal lab results, his symptoms, and the smooth, firm enlargement of his prostate, Troy is diagnosed with BPH  Before any treatment strategies are initiated Troy is counseled about this diagnosis  He is reassured that it is a benign disease but that it may progress, or symptoms may stay the same or improve  Surgery is not recommended to Troy Diagnosis:BPH BPH = Benign Prostatic Hyperplasia

MODULE 5 Case 2: Troy 26/46 What Would be Your Management Strategy for Troy?

MODULE 5 Case 2: Troy 27/46 Management Strategy  Troy is offered the options of either watchful waiting or pharmacological treatment  Troy elects pharmacologic treatment:  Troy is prescribed combination therapy with a 5α–reductase inhibitor and an α 1 -blocker  This combination should relieve the obstructive symptoms, as well as shrink his prostate  A moderate exercise regime is recommended for Troy, as well as cutting back on his red meat and caffeine intake  Troy says he is relieved to know that his problem is not likely to be related to cancer because he has a friend who recently died from that disease

MODULE 5 Case 2: Troy 28/46 Note:  Combination therapy results in more symptom amelioration than either medication alone  In addition it has the best possibility of preventing BPH progression (prevents future deterioration of symptoms, acute urinary retention and eventual surgery) Troy’s TreatmentRationale Combination Therapy: 1.5α – reductase inhibitor AND 2.α 1 - blocker Shrink the gland AND Relieve the obstructive symptoms Treatment Strategy BPH = Benign Prostatic Hyperplasia

MODULE 5 Case 2: Troy 29/46 Discussion  α 1 -blockers work quickly to reduce symptoms while 5α-reductase inhibitors slowly reduce the size of the prostate and eventually reduce symptoms  It is the reduction in size of the prostate and prevention of growth that results in prevention of BPH progression BPH = Benign Prostatic Hyperplasia

MODULE 5 Case 2: Troy 30/46 When Would You Expect Troy’s Treatment Options to Show Some Effect?

MODULE 5 Case 2: Troy 31/46 Time to Effect Time to take effect: α 1 -blocker: a few days – 1 week 5α-reductase inhibitor : up to six months

MODULE 5 Case 2: Troy 32/46 Troy Asks About Phytotherapy for BPH. What Do You Tell Him? BPH = Benign Prostatic Hyperplasia

MODULE 5 Case 2: Troy 33/46 Would You Do Anything Different if Troy had High Blood Pressure and was Taking Antihypertensive Medication?

MODULE 5 Case 2: Troy 34/46 Discussion Regarding Thiazide Diuretics  If Troy was taking a thiazide diuretic:  Non-selective α 1 - blockers, such as terazosin and doxazosin, may cause postural hypotension in patients already receiving antihypertensives  Non selective α 1 - blockers are no longer indicated as first line agents for the treatment of hypertension because of adverse outcomes (see Canadian Hypertension Guidelines -  Non-selective α 1 - blockers by themselves are not a good choice for monotherapy to treat BPH and hypertension  The selective α 1 - blockers, tamsulosin and alfuzosin do not tend to cause clinically significant hypotension and can be used in conjunction with thiazide diuretics BPH = Benign Prostatic Hyperplasia

MODULE 5 Case 2: Troy 35/46 What Would Be Your Follow-up Strategy For Troy?

MODULE 5 Case 2: Troy 36/46 Follow-up Strategy  Following your instructions, Troy will make sure he requests an IPSS and QoL questionnaire from the receptionist each time he arrives for his follow up appointments  He will come about 10 minutes early for his appointment so he can fill it out in the waiting room before he sees you IPSS = International Prostate Symptom Score QoL = Quality of Life

MODULE 5 Case 2: Troy 37/46 Follow-up Appointments for Troy What Would your Likely Course of Action be at Each Visit?

MODULE 5 Case 2: Troy 38/46 Follow-up Appointments for Troy 2 weeks  If a non-selective agent has been chosen the dose must be titrated upward balancing effectiveness against hypotension  Selective α 1 -blockers do not need titration and we might expect some improvement of symptoms at this stage  Maintain the 5α-reductase inhibitor 4-6 weeks  Troy reports mild relief of his urinary symptoms  The dose of selective α 1 -blocker is maintained  The dose of the non-selective α 1 -blocker may need to be titrated depending on his extent of symptom relief  Maintain the 5α-reductase inhibitor 3 months  Moderate symptom relief is reported  The dose of non-selective or selective α 1 -blockers is maintained  Maintain the 5α-reductase inhibitor

MODULE 5 Case 2: Troy 39/46 6 months  He reports moderate relief of irritative and obstructive symptoms  His score on the IPSS has dropped from 17 to 12  He answers 3 to the quality of life question (less bother)  The dose of α 1 -blocker is maintained  Maintain the 5α-reductase inhibitor 9 months  If Troy’s 6 month visit is promising, this visit can be skipped  Monitor Troy’s urinary symptoms  The dose of α 1 -blocker is maintained  Maintain the 5α-reductase inhibitor IPSS = International Prostate Symptom Score

MODULE 5 Case 2: Troy 40/46 Discussion  What do you expect Troy’s PSA value to be at 12 months?  How frequently would you perform the DRE?  What examinations and tests would you perform at 1 year?  When, if ever, would you consider changing his therapy? PSA = Prostate-Specific Antigen DRE = Digital Rectal Examination

MODULE 5 Case 2: Troy 41/46 12 months  Troy’s IPSS is now 10 and he has greatly improved  His quality of life has improved (no bother)  Perform a physical exam including DRE, urinalysis, and PSA, and serum creatinine is optional  The dose of α 1 -blocker is maintained  Maintain the 5α-reductase inhibitor  His PSA is 0.8ng/ml  DRE: Normal years  An option is to remove Troy from the α 1 -blocker and see if he still requires it for symptom relief  Maintain the 5α-reductase inhibitor Yearly follow-ups  Unless Troy experiences increased severity of symptoms, a yearly DRE and PSA is recommended as well as IPSS and QoL  Note: Troy’s DRE is normal and his PSA levels have reduced and there is no need to refer him to a urologist IPSS = International Prostate Symptom Score PSA = Prostate-Specific Antigen DRE = Digital Rectal Examination QoL = Quality of Life

MODULE 5 Case 2: Troy 42/46 Long Term Management  How would you manage Troy after 2 or 3 years if he no longer has any bothersome symptoms based on his IPSS and QoL? IPSS = International Prostate Symptom Score QoL = Quality of Life

MODULE 5 Case 2: Troy 43/46 Long Term Management  Consider stopping the α 1 -blocker and see if he still needs it.  Continue to monitor DRE and PSA as usual routine. DRE = Digital Rectal Examination PSA = Prostate-Specific Antigen

MODULE 5 Case 2: Troy 44/46 Long Term Management  What kind of lifestyle options would you counsel Troy on, to help with his symptoms?

MODULE 5 Case 2: Troy 45/46 Long Term Management  If he wants to take multivitamins, consider vitamin E and selenium and perhaps lycopenes since they may be shown in future studies to be important for prevention of prostate cancer.  He no longer has any bothersome symptoms so no direct advice other than:  Good diet  Exercise  Avoidance of anything that causes recurrence of his symptoms
