Presentation on theme: "Chairman Department Radiation Oncology Sophia Gordon Cancer Center"— Presentation transcript:
1Chairman Department Radiation Oncology Sophia Gordon Cancer Center Thank you for the opportunity to engage in this exchange of ideas regarding responsible screening for lung cancer through the use of LDCT scanning. I will ask you to consider several somewhat controversial, novel, and provocative concepts over the next 45 minutes. If you find that you are at times uncomfortable, that’s ok. Please take a few days to consider these ideas before you decide what you surmise of them. I know it has taken me time to develop my thinking on these topics, particularly the notion of offering lung screening for free……..which in my experience can take most people a little time to get used to……...Andrea McKee, M.D.Chairman Department Radiation OncologySophia Gordon Cancer CenterLahey ClinicMay 15, 2012
3Outline Lung Cancer Background Lung Cancer Screening at Lahey Clinic Incidence/MortalityNational Lung Screening Trial (NLST)National Comprehensive Cancer Network (NCCN)Lung Cancer Screening at Lahey ClinicProgram StructureStructured ReportingLUNG-RADS Classification SystemChallengesRescue Lung, Rescue LifeWe will begin with some background information on lung cancer statistics, review the IELCAP and NLST results, and the most recent NCCN and American Lung Association recommendations. We will discuss some of the identified risks and benefits of screening for lung cancer.We will then discuss a model for the delivery of free lung screening developed at my center, the Lahey Clinic in Massachusetts which will include our system for structured reporting, the LUNG:RADS classification system: this system was developed in an effort to reduce unnecessary testing of patients, and ensure appropriate follow-up and communication of results to all parties involved. I will outline some of the challenges we faced during the development of this program and some of the ideas we have to help other centers avoid or minimize such difficulties.We will conclude with a discussion of the Rescue Lung, Rescue Life awareness and advocacy campaign with its primary objective……..to save lives through open access to responsible screening.
4Lung Cancer Incidence/Mortality: US Number one cause of cancer-related death in the US and WorldKills more women than Breast, Ovarian, and Uterus Cancer Combined200K new cases/yr 160K deaths/yrLung cancer is the number one cause of cancer-related death in the US and WorldLung cancer kills more women than breast, ovarian and uterine cancer combined. If you ask most people they will be surprised by this fact, generally thinking that breast cancer is the number one killer of women. This is probably because of the effective advocacy campaigns in this country for breast cancer awareness and research. NFL and NBA players wearing pink sweatbands and sneakers are a good example of this.References: Jemal A, Bray F, Center MM, et al. Global cancer statistics.

5Risk Factors?A current or former history of tobacco use is the primary risk factor for 85% of patients diagnosed with lung cancer. In this slide you see the cancer here, and the risk factor here on the patient’s anterior chest wall.
6Tobacco Trends History of tobacco use Higher prevalence Higher risk <20% in 200642% in 1965Demonization campaignHigher prevalenceMilitary (1 in 3) vs (1 in 5)Less educatedHigher riskRescue workersOccupational exposureI applaud the efforts of organizations such as the American Cancer Society to reduce the prevalence of tobacco use in this country. Here you see an advertisement of a pig smoking a cigarette….. with the implication being that smoking is a dirty habit but unfortunately runs the risk of equating smokers with pigs. This type of advertising has been effective along with other legislative efforts to decrease the rates of tobacco use from 42% in 1965 to <20% in Unfortunately, we are not seeing the same patterns of reduced tobacco use in developing countries and there has been a price levied by the demonization campaign developed to achieve this reduction. I fear we may be paying that price now, as many people feel we should not be allocating resources to help save the lives of current or former smokers. Put in historical perspective, smoking was at one time widely accepted. Many still practicing in medicine can recall a time when physicians and nurses smoked in the nurse’s station, physician’s lounge and surgeon’s lounge. There are many outstanding individuals contributing greatly to their respective fields who died of tobacco related illnesses, Peter Jennings, George Harrison, Babe Ruth, to name just a few.There is a much higher rate of tobacco use among military personnel. Former enlistees in the armed services were encouraged to smoke due to the stimulating and sedating effects of nicotine. Many were given a free carton of cigarettes upon enlistment. I have great respect for the men and women who have risked their lives to defend this country. I feel we are at a point in time when the medical and political communities have an opportunity to demonstrate that respect through awareness and advocacy of lung screening. Even now, there remains a higher prevalence of tobacco use in the military where one in three smoke vs one in five in the general population. Currently, there is also higher smoking prevalence seen amongst lower socio-economic groups.There are groups of current or former smokers who are at higher risk for the development of lung cancer due to occupational exposures, such as fire fighters, rescue workers, Navy ship builders, and construction workers. The medical community must begin the process to educate the public about these combined risks and the evidence which demonstrates we now have a tool to help protect those at risk.
7Tobacco TrendsNot to mention the stiff competition and mixed messaging put forth by the tobacco industry, Hollywood, and a variety of other multitude of media venues. Here is a mixed message on this slide. The beauty of Scarlett Johansen vs our smoking pig. As a medical community and a society we should probably look to guard against with holding of healthcare services and advocacy based on social history………… for this could result in a very slippery slope. And where do you draw the line? What about obesity, alcohol use, tanning booth usage, unprotected sexual activity and the variety of other risk factors known and unknown that people engage in everyday. Again…….where do you draw the line?Competition has been tough - tobacco industry, Hollywood, pressGuard against withholding of health care services or advocacy based on social history – slippery slope
8Lung Cancer Incidence/Mortality: US Primary Prevention (Smoking Cessation) SuccessDecreased number of overall lung cancer deaths in USDespite success 160K still die every year from lung cancerMost people who die from lung cancer now are FORMER SMOKERSTo be clear, smoking cessation and primary prevention remains of critical importance in our plight to decrease the overall number of lung cancer deaths. Despite the successes in primary prevention however, one hundred and sixty thousand patients die of lung cancer each year in the US alone. Furthermore MOST people who die from lung cancer nowadays are FORMER SMOKERSReferences: Jemal A, Bray F, Center MM, et al. Global cancer statistics.

The majority of patients at risk for lung cancer are not currently using tobacco products. And despite all the medical advances we have seen over the past several decades the 5 year overall survival for lung cancer remains largely unchanged being 12% in 1975 and now 15% in LDCT is a medical advance that WILL finally allow us to see significant improvements in 5 year overall survival as we will discuss later on in this session.References: Jemal A, Bray F, Center MM, et al.

They have done the heavy lifting, done what we have told them, and quit. Yet, they remain at risk, and they are aware of this. What more can we do to help them? This is where secondary prevention, or lung screening enters the discussion. Find the disease at the earlier more treatable stage and decrease mortality, not incidence.References: Jemal A, Bray F, Center MM, et al. Global cancer statistics.

11Lung Cancer Screening Data to support screening been around awhile NEJM October 200631,567 patients baseline screened with low dose CT from484 lung cancers detected (85% clinical stage I)10 year survival 92% for those having surgery8 patients refusing therapy died within 5 years of diagnosisLDCT for lung screening has been around awhile. Dr. Claudia Henschke and the IELCAP (International Early Lung Cancer Action Program) has been investigating the use of LDCT for lung screening since the early 1990’s. In 2006 they reported their results in the NEJM on almost 32,000 patients screened from They detected 485 lung cancer 85% of whom were in clinical stage I and demonstrated a 10 year 92% overall survival for those treated surgically. The 8 patients who refused therapy died within 5 years of the diagnosis. Concerns regarding lead-time bias and over diagnosis prevented the widespread adoption of lung screening in the wake of this publication. Most physicians and medical associations have been waiting for the results of the National Lung Screening Trial to answer these concerns in a randomized fashion.
12Lung Cancer Treatment NSCLC: Unscreened Population Stage I, II, IIIAPotential CureSurgical resectionRadiotherapyChemotherapyStage IIIB/IVPalliativeThe treatment of lung cancer, similar to other malignancies is stage dependent. Earlier stages are treated in a potentially curative fashion with surgery, radiation, or a combination of the above plus chemotherapy. Treatment Stage IIIB and IV is mainly palliative in nature. Survival in an UNSCREENED population ranges from 72% for the earliest stage IA to <10% for the most advanced stages.Goldstraw P, Crowley J, Chansky K, et al.

J Thorac Oncol 2:706–714.
13National Lung Screening Trial Results: Stage Shift Unfortunately in the unscreened population 70% of patients will present with stage III and IV disease and only 30% will have stage I or II disease at presentation. This data from the NLST demonstrates stage shifting where the opposite is seen with LDCT screening – 70% of patients present in stage I and II and 30% will have later stage disease at presentation.
14Stage IV NSCLC <1% = 5 year OS Here is a PET scan commonly seen in Oncology of a patient with stage IV NSCLC. The patient has a left lobe primary tumor with metastases to a contralateral hilar node, the ipsilateral adrenal gland and the liver. The 5-year survival for this patient is <1%<1% = 5 year OS
15Incidental Finding on CXR Stage T1BN0In the absence of screening, patients who have been cured of lung cancer, for the most part have had their disease discovered incidentally on a CXR or diagnostic CT. Only a few symptomatic patients with lung cancer are cured of their disease. This gentleman has a 58% 5-year overall survival after his stage IB lung cancer was diagnosed during a pre-operative CXR evaluation prior to hip replacement. He had no symptoms of lung cancer.58% 5-year Overall SurvivalGoldstraw P, Crowley J, Chansky K, et al.

16Annals of Internal Medicine October 2011 62 year-old female with a history of well-controlled hypertension presents for routine follow-up. She is asymptomatic and feels well. She has jogged 3 miles 3 times weekly for years with no recent change in exercise tolerance. She has a 30 pack-year history of tobacco use but quit 10 years ago. Normal physical exam. She read a recent study that found a benefit to screening with LDCT and inquires if this is appropriate for her?What should you recommend?This case is from an article in the October 2011 issue of the Annals of Internal Medicine. They present a case of a 62 year-old female with a history of well-controlled hypertension seen in routine follow-up. She has jogged 3 miles a day 3 times a week for years with no recent change in her exercise tolerance. She has a 30 pack-year history of tobacco use but quit 10 years ago. She has a normal physical exam. She recently heard about a study, which demonstrates a benefit to LDCT and inquires if this is appropriate for her. What do you recommend?
17Secondary Prevention Preclinical Diagnosis: Screening Awareness 5mm nodule6 month fu diagnostic CT recommended7mm NSCLC treated with lobectomy and nodal evaluationT1aN0 (screened)Let’s say you discuss the risks and benefits of screening and she makes the informed decision to undergo LDCT testing. There is a 5 mm nodule found and it is recommended by the radiologist that she have a follow-up CT scan in 6 months. The patient calls wanting to know if she should be worried. What can you tell her? Based on the NLST results this is not uncommon. You can remind her that during the first year of screening, there is a 27% chance that there will be a finding in the lung that requires follow-up. The vast majority of these findings are handled through follow-up imaging. There is a 96% chance that she doesn’t have cancer. If she is one of the 4% who has a screened 5 mm (screened IA) lung cancer, there is a 92% chance that she will be cured with appropriate therapy, that is why she underwent the screening. 6 months later the nodule increases to 7mm.What is this patient’s 5-year overall survival?
18Secondary Prevention Preclinical Diagnosis: Screening Awareness She is found to have a screened pathologic IA NSCLC at the time of surgery. The patient has a 92% 5-year OS.92% = 5 year OS
19Secondary Prevention Preclinical Diagnosis: Screening Awareness 85% of patients in screened population have stage I lung cancerAsymptomatic58% 5-year OSThis is the idea behind secondary prevention. Detect the disease by looking for it at the more curable 92% survival stage, versus finding it by accident with a 58% 5 year OS, or waiting for symptoms to develop with a dismal prognosis.ScreeningSymptomaticStage I92% 10-year OSStage IV1% 5-year OS

22National Lung Screening Trial (NLST): 6/29/2011 The National Lung Screening Trial (or the NLST) was published in the NEJM on-line in June of 2011 and in paper publication last August. The authors concluded that screening with the use of LDCT reduces mortality of lung cancer.National Lung Screening Trial Research Team (2011) Reduced lung-cancer mortality with low-dose computed tomographic screening.

Baseline prevalence scans were performed followed by 2 additional screens - so three scans over 2 years. A positive test was defined as a non-calcified nodule greater than 4mm in diameter or other findings suspicious for lung cancer like adenopathy or effusion. Work-up was determined by the patient’s primary care physician, NOT the NLST. HOWEVER, the NLST reading radiologist’s recommendation was available.

There was a 6.6% reduction in overall mortality that was not statistically significant when lung cancer deaths were excluded.National Lung Screening Trial Research Team (2011) Reduced lung-cancer mortality with low-dose computed tomographic screening.

The annual incidence decreases to .5-.8% (such that one in one hundred and TWENTY FIVE) have cancer on the incidence screens. You will not detect small cell lung cancer at earlier stages and so the screening benefit applies only to non-small cell histologies. The number needed to screen is This means that for every 320 patients screened we will save one life. This will result in tens of thousands of lives saved per year if we implement responsible screening and access across the US.National Lung Screening Trial Research Team (2011) Reduced lung-cancer mortality with low-dose computed tomographic screening.

28National Lung Screening Trial Results: Rate of Positive ScreeningsAq CT (24.2%) > 3x more sensitive than CXR (6.9%)T0 & T1 Rate: %T2 Rate: %2 year stability benign (Fleischner Guidelines)Expected rate for ongoing LDCT screeningAt least one positive result (3 screens): %Significant incidental finding: %Not screening everyone – highly selected group (3%)Not surprisingly, LDCT is more sensitive approximately (3 times more sensitive) than CXR. On the first 2 screens there is a 27% chance for a lung finding. After that the rate decreases to 16.8% which is the expected rate for an ongoing LDCT screening program. Any solid nodule that has been stable for 2 years is considered benign according to the NLST and Fleischner Guidelines. The risk for a significant incidental finding is 7.5%. The NLST group is a highly selected group and is expected to represent approximately 3% of the population or approximately 7 million patients in the US.National Lung Screening Trial Research Team (2011) Reduced lung-cancer mortality with low-dose computed tomographic screening.

Invasive diagnostic procedures on patients who didn’t have cancer were rare at 2.6%. The complication rate for patients who didn’t have cancer was also rare at 1.4%. The major complication rate for those without cancer was very rare at .06%. FOR PATIENTS WHO HAVE CANCER the risk for major complication was 11.2% and the surgical resection mortality rate was 1%. But remember, these patients actually have cancer.
30NLST Results: False Positive Workup/Adverse Events False Positive Rate:20-25%: Chance you will end up with a false positive~10-12% for Mammography (“Call back”)False Discovery Rate (1-PPV):96%: Chance if you are positive you do not have cancerSame as mammographyFalse Positive Biopsy Rate%: Chance if screened you will have an unnecessary invasive procedure (LDCT)7-15%: Chance if you end up having a biopsy it will be negative (mammography).IF we compare to mammography, (something we are all familiar with) the discovery rate (or the chance that you will get a “call-back” for additional imaging) is 20-25% for LDCT and 10-12% for mammography. With LDCT the “call-back” occurs in 3 to 6 months, with mammography, the patient is immediately “called-back”. The false discovery rate – meaning the chance that you don’t have cancer if you get called back is 96% for both LDCT and mammography. The false positive biopsy rate (meaning the chance that you have a biopsy when you do NOT have cancer is % for LDCT and 7-15% for mammography.

The NCCN considered the risks and benefits of lung screening in the development of their guidelines, which I recommend you read, because they are quite well done.After weighing all these considerations……
32National Comprehensive Cancer Network (NCCN): 10/26/2011 They issued a category I recommendation to screen the NLST population. Category I is uniform consensus based on the highest level of evidence available that the intervention is appropriate.NCCN Guidelines® for Lung Cancer Screening (V )
33NCCN Recommendation Categories A category 2B recommendation was issued for the patients who are found to be at high risk based on previous non-randomized publications. Category 2B is based on lower level evidence there is NCCN consensus that the intervention is appropriateNCCN Guidelines® for Lung Cancer Screening (V )
34NCCN Recommendation Categories For comparison purposes Mammography has a category 2A recommendation to screen.NCCN Guidelines® for Lung Cancer Screening (V )
35NCCN High-Risk GroupsHere are the 2 NCCN high-risk groups. These are the 2 high-risk groups to whom we are offering free screening at our center. In Group 2, the age is lowered to 50 and the pack-years is lowered to 20. There is no timeframe for when the patient quit and one other risk factor is identified not to include exposure to second hand smoke
36NCCN High-Risk Group 2 Risk Factors Personal Cancer HistoryLung, lymphoma, smoking related cancersFamily History Lung Cancer in 1st Degree RelativeChronic Lung DiseaseEmphysemaPulmonary FibrosisCarcinogen ExposureArsenic, asbestos, cadmium, chromium, diesel fumes, nickel, radon, silicaHere is a list of the secondary risk factors with family history, previous cancer related tobacco history, COPD or emphysema co-morbidity, and exposure to known carcinogens among them.
37NCCN Guidelines Solid or Part Solid Nodules Follow-up Here is the decision tree-which is based on the NLST and IELCAP studies. The recommendations for imaging follow-up are based on the characteristics and the size of the finding. Nodules smaller than 4 mm are not considered positive with 12 month annual screen follow-up. A patient with a nodule greater than 4mm but less than 6mm should have LDCT scan in 6 months. Nodules between 6 and 8mm should be followed with LDCT in 3 months and any solid or part-solid nodule greater than 8mm is recommended to have more immediate work-up.NCCN Guidelines® for Lung Cancer Screening (V )
38Lung Cancer Screening Risks and Benefits (NCCN) Here are the risks and benefits the NCCN identified. Notice anxiety is listed as both a risk and a benefit. In our experience thus far, patients are less anxious when they are properly informed regarding screening as a process and they are able to access a tool that can help protect them against lung cancer mortality. Let us cover the issues of pseudo-disease (or over diagnosis), unnecessary testing, radiation exposure, and cost in more detail.NCCN Guidelines® for Lung Cancer Screening (V )
39Overdiagnosis, Survival, Mortality Let’s start first with this issue of over diagnosis or pseudo-disease and in so doing develop some clarification on the difference between a survival benefit vs a mortality benefit. Starting with survival. If the red star represents diagnosis of lung cancer and the lightning bolt death, the top line represents patients undergoing LDCT and the bottom line is CXR. You can see that in this scenario there is a survival advantage. However, even though technically patients are surviving longer with a diagnosis of cancer, they live no longer than had they been diagnosed later. This difference here is a lead-time bias.DiagnosisDeath
40Overdiagnosis, Survival, Mortality Contrast that with a mortality benefit where again you have LDCT on top and CXR on the bottom. But death due to lung cancer occurs at a later time point in the LDCT arm. In this scenario, the issue of lead-time bias is mitigated by the fact that patients are in fact living longer than they would have had they been screened with CXR. Statisticians calculate the mortality difference here based on the factors of numbers of patients and how much longer they are alive in a construct known as person yearsDiagnosisDeath
41Lung Cancer Mortality Survival Mortality Diagnosis Death When you isolate death sue to lung cancer only, the mortality difference is 20%. Here you see 443 patients had died at the study endpoint in the CXR arm and MUCH FEWER…… 365 patients had died in the LDCT arm.365Death due to lung cancer = 20%443DiagnosisDeath
42Overall Mortality Survival Mortality Diagnosis Death When you look at death due to any cause across the entire group of patients regardless of whether or not they had been diagnosed with lung cancer, the mortality difference is approximately 7% deaths in the CXR arm and 1877 deaths in the LDCT arm, telling us that we are not unduly harming patients through the process of screening and treatment of early-detected lung cancer1877Death due to any cause across entire group= 6.6%2000DiagnosisDeath
43Overall Survival Benefit 7% Adjuvant Therapy Reduces Risk Breast cancerACT chemotherapy5 years anti-estrogen therapyPost-mastectomy RTProstate CancerPost prostatectomy RTHead and Neck cancerPost-operative chemoRTCervix CancerMedical-legal consequencesWhat other treatments confer a 7% survival benefit in oncology? Here is a list of interventions associated with a similar benefit that we use to treat cancer patients in order confer that advantage…….months of risk-adapted systemic chemotherapy or chest wall radiotherapy after mastectomy in patients with breast cancer, risk-adapted post-operative radiotherapy to men with prostate cancer, risk-based post-operative chemoradiotherapy to patients with head and neck cancer or cervical cancer. These are NOT trivial treatments. Given the survival advantage associated with them, we in oncology would place ourselves at significant medical legal risk were we not to offer them (or at a minimum, discuss these treatments as options for therapy with our patients). In light of the NCCN category I recommendation to screen, we in oncology, became concerned about the medical legal risk for our PCPs were they not to systematically review the risks and benefits of screening with their at-risk patients.
44Overdiagnosis Determine time and cause of death in those patients diagnosed and treated for lung cancerMortalityHere we look at the time and cause of death for ONLY the cohort of patients diagnosed and treated for lung cancer. A patient who dies of other causes, be it they died of heart disease, emphysema, or a fatal ski accident 2 years after surgery for a low-grade (formerly BAC) adenocarcinoma, or in its most extreme example were hit by a bus 2 days after their lobectomy for lung cancer was overdiagnosed. Overdiagnosis is inherent to any screening program. It is estimated to be about 15-20% in lung cancer screening, but we will never actually know. This is because 1) There is no observation arm in the NLST. The control arm was CXR which is not observation and 2) We must wait for patients in the study group to die before we can calculate the rate of overdiagnosis, when the NLST halted their trial the CXR group was appropriately advised of the mortality benefit with LDCT and therefore cross-over will prevent us from knowing the true rate of overdiagnosis of LDCT when compared with CXR. We do know that overdiagnosis decreases with time, it does not increase with time.DiagnosisDeath
45CT Lung Cancer Screening Morbidity Radiation exposureMDCT resolution allows for dose reductionLDCT <1mSv, Mammography 0.7mSvLet’s switch gears to radiation exposure. Here you see 2 CT scans of the same patient. The one on the left is a LDCT performed with multi-detector imaging on the right is a standard diagnostic CT. The LDCT exposes the patient to <1mSv, similar to a bilateral 2-view mammogram, and maintains its diagnostic capabilities for pulmonary nodule detection at one tenth the dose of the one on the right with its associated 10mSv exposure.1 mSv10 mSv

LDCT exposure is similar to a mammogram. A Lumbar spine film series is 2mSv or the equivalent of 2 years of annual LDCT scanning. Triphasic CT abd/pel is 25mSv. Background exposure is 3 mSv at sea level and 4.5mSv in Denver Colorado. Occupational exposure for a radiation worker such as myself is 50mSv, I am allowed each year to be exposed to the equivalent of 50 LDCT studies. A transatlantic flight is .1mSv such that 7 transatlantic flights equals 1 LDCT. Also an important consideration regarding radiation risk is the year latency period to develop secondary malignancies as a result of RT exposure. The average age of patients in screening programs is So…. we are not talking about screening healthy children, teenagers, or even young adults. With a year latency period the risk is acceptable at these exposures, when weighed against the knowledge that one in one hundred of these patients has lung cancer.year latency period to develop secondary malignancies from RT exposureAverage age of patients in screening trials is 62

48LUNG RADS Lung Number Category “S” Category Category 1: Negative (12mo)Category 2: Negative with benign pulmonary findings (12mo)Category 3: Positive/likely benign (follow-up per NCCN guidelines)Category 4: Positive/suspicious for malignancyCategory 5: Known cancerPositive for extra-pulmonary finding not suspicious for lung cancer but requiring clinical follow-upThyroid massAneurysmKidney MassOur LUNG RADS system has both a lung number category and an “S” category which is either positive or negative for any potentially significant extra pulmonary finding. Category 1 is negative – return next year for annual screen Category 2 is negative with benign pulmonary finding such as a nodule than has been stable for more than 2 years – return next year for annual screen. Category 3 is Positive/likely benign – recommendation for follow-up per the NCCN guidelines % of your cases will fall into this category depending upon which year of screening the patient is in. Category 4 is positive - suspicious for malignancy. These patients are sent back to their PCP with a recommendation for pulmonary consultation to determine direction of further evaluation. Category 5 we shouldn’t really be seeing because these are patients with recent known lung cancer who should be receiving follow-up care under the direction of followed their oncology team. Examples of an S positive study would include findings such as a thyroid mass, aneurysm, or kidney mass.

Lung screening is a process, which occurs over time, that is how we avoid unnecessary biopsies and invasive procedures, by handling the findings with further radiographic studies and waiting to intervene once growth of a small nodule has been established. When we think about screening in breast cancer, or prostate cancer, the patient, and provider hopes to pick up the cancer at the earliest possible screen, - at the first sign of an elevation in PSA or abnormality on mammogram. For we tend to intervene early and thus it is less common to wait 6 months to establish a change before moving to path diagnosis. Contrast that with lung screening where if you know right away that the patient has cancer (category 4), you may or may not save that patient’s life. It is the category 3 group (96% of whom don’t actually have cancer) whose lives you will save through screening (the 4% of category 3 patients who actually have cancer will have the potential for the 92% survival rate).
50Cost per life-year saved would be below $19,000 An Actuarial Analysis Shows That Offering Lung Cancer Screening As An Insurance Benefit Would Save Lives At Relatively Low CostCost per life-year saved would be below $19,000Last month the Milliman group published this report in Heath Affairs magazine “An Actuarial Analysis Shows That Offering Lung Cancer Screening As An Insurance Benefit Would Save Lives At Relatively Low Cost”. This well known actuarial group developed a model based on the IELCAP data to determine that the cost per life-year saved would be below $19,000. The NLST group are coming out with their own estimate for quality adjusted cost per life year saved which by report, a back of the envelope estimation has put the number at $38,000. We can all argue about which model and which assumptions to use, but the fact of the matter is that……Pyenson et al, Health Affairs 31, No : April 2012
51Cost-Effectiveness Private Insurance Coverage 11/2011 Anthem California12/2011 WellpointAs of late fall 2011 both Anthem of California and Wellpoint 2 of the nation’s largest insurers are covering this benefit for those patients meeting the NLST criteria. One must ask why? I can’t imagine they are doing so in order to attract 55 to 74 year old current or former heavy smokers to their programs. They must have reviewed their own actuarial data and determined the cost benefit to be present. Any one of us involved with the treatment of stage III and IV lung cancer should not be surprised by this information given the cost associated with diagnostic scans, chemotherapy, and radiation to palliate and treat end-stage disease.
52Productivity Loss due to Cancer Not to mention the considerable lost revenues associated with productivity loss due to lung cancer – an estimated 36 billion per year……..much greater productivity losses for lung cancer than what is seen for any of the other malignancies listed here…………considerable indeed.

The Advisory Board Company surveyed participating centers in March of 2012 and found that 32% of participating centers offer lung screening while 77% of those not offering screening plan to do so in the next year. Most LDCT screening programs have started sometime over the past 9 months. The mean number of patients screened in programs that offer screening is 70 for the year % of patients pay out of pocket with a self-pay rate between ( dollars). The average rate across centers who doscreen is $230.The Advisory Board Company 3/12
54The Advisory Board Company 3/12 Furthermore, the Advisory Board learned through their poll that the key driver for reason to start a lung screening program is the desire to improve patient outcomes – which is not surprising because most clinicians and administrators are genuinely concerned for the well-being of the patients they care for. For those centers not considering CT screening, the most common reason cited was lack of reimbursement – also not surprising.The Advisory Board Company 3/12
55Barriers to Screening Applicability to patients outside study group? Duration of screening?Education/awareness/endorsementAccess to care in the absence of established reimbursement – Rescue Lung, Rescue LifeSome other barriers to screening we have heard expressed are concern raised over the applicability to patients outside the study group and how long to screen for? It is true there may be others who will benefit from lung screening. Additional research will be required to determine if there are others who should be screened, but that should not stop us from screening those now whose lives we know have the potential to be saved through screening. The NCCN has given us a good start regarding duration of screening based on the evidence we do have. The current lack of public and medical education surrounding the topic, particularly in the wake of years and years of debate and confusion associated with lung screening is a barrier which has been compounded by the relatively slow endorsement of this modality by expert specialty and advocacy groups. But the number one issue we hear time and time again is how to make the test equally available to those at risk in the absence of established reimbursement and in light of a several hundred dollar self pay rate barrier.

The study polled 962 general practitioners and found that only 38% had not offered screening to patients. The majority of patients screened were offered a CXR with 55% and 22% had been screened with LDCT. On multivariate modeling the authors found that physicians were more likely to screen if they felt that screening was endorsed by expert groups, was shown to be effective, or when patients asked about screening.Klabunde, PhD et al: Annals of Family Medicine Vol. 10, No.2 March/April 2012
57Lung Cancer Screening Practices of Primary Care Physicians: Results From a National Survey “To date, because of a lack of evidence from rigorous studies, major expert groups have not recommended screening asymptomatic individuals, even those with heavy or long-term smoking histories, for lung cancer”US Preventative Services Task ForceAmerican Cancer Society 2009 guidelinesAmerican College of Chest PhysiciansAlthough I found this information interesting because it clearly demonstrates a lack of consensus and confusion regarding screening practices in this country, the crux of the article was upsetting, as the authors went on to say “To date, because of a lack of evidence from rigorous studies, major expert groups have not recommended screening asymptomatic individuals, even those with heavy or long term smoking histories, for lung cancer”. They go on to site the US Preventative Services Task Force who has openly admitted the need to review their position on LDCT lung screening in light of the NLST results; they cite the old 2009 American Cancer Society Guidelines, and the American College of Chest Physicians. I’d like to know what the authors consider a rigorous study, if not the NLST? If we do not consider a 300 million dollar, multi-institutional, NCI funded, randomized trial with 54,000 patients that was closed early due to the statistically significant mortality advantage a rigorous study, then we probably should not have conducted it.Klabunde, PhD et al: Annals of Family Medicine Vol. 10, No.2 March/April 2012

In the very same month as the Annals of Family Practice publication was released, APRIL of 2012 the American Lung Association released their new guidelines. The American Lung Association is considered one of the world’s leading organizations working to save lives by improving lung health and preventing lung disease through Education, Advocacy and Research. There new guidelines are as follows:Best way to prevent lung cancer is to never smoke or quitLDCT for NLST group recommended - they do not say how often or for how long which will need to be clarified by themDo NOT screen with CXRLDCT is not for everyoneALA to develop public health materials to educate patientsCall to action to hospitals and screening centers to screen responsibly – including concern over access issues in the absence of reimbursementNow that several important expert groups have endorsed screening, I suspect many more will follow.

Professional Societies whose mission is to reduce cancer mortality and improve the health of patients with lung disorders, cannot remain silent at this pivotal time in cancer history. Now is the time to lead.
60Why Free?EthicalMake lung screening available for all socioeconomic groups until CMS reimbursesPower of FreeHuman MotivationFew people screened when chargeHelping to Raise AwarenessMultidisciplinary centers may not need to charge (TBD)Seize Opportunities to fulfill Hospital MissionSave Lives, Growth,Innovation, Sustainability, TeamworkI’d now like to switch gears to discuss Free Lung Screening and the established program at Lahey Clinic. Let’s start with why free? First, it is a way to provide screening access to all those at high-risk for lung cancer regardless of socioeconomic status until reimbursement is established. We offered LDCT for 9 months at a self-pay rate of $300 and we screened 4 patients all of whom were from our concierge level executive health program and could afford the screen. Since we started free screening on January the 9th we have screened over 230 high-risk patients with no advertising of the program other than a CME campaign, global messaging to our employees, and our hospital Intranet. Second, when something is offered for free, it calls attention to itself. There is something about the word FREE that calls upon people to listen. People are motivated towards reduced pricing and free products. Take the long waits, lines, and chaos associated with Black Friday for example….. Or Taco Bell where people will wait over an hour in line for a free taco that normally costs 99 cents. The FREE nature of this program, is what is helping to make providers, patients, and administrators pay attention to this critically important issue. I imagine some are offended at the notion of offering a complex, intricate, highly sophisticated service like CT screening that is not without risk to the patient (or the provider), and requires years of collective training and combined expertise, for free. After all, we are not in the fast food service industry……. we are in the healthcare industry and offering our services for free devalues the currency of our other services. I agree the solution is not perfect. But what choice do we have???…………we ARE in the health care industry…… Is it better to knowingly let people die? It will likely be several years before CT screening becomes a uniformly covered benefit. In the meantime, there exists uniform consensus to screen within the NCCN and an American Lung Association recommendation to screen high risk patients. Free lung screening is an interim measure…… a construct developed in response to an unprecedented time in cancer history when we find ourselves absent equitable reimbursement, but now aware of the potential to save tens of thousands of lives, but ONLY if we make the service available to the over 9 million at risk in this country. It is not enough for only a few centers to open access…..access must open across the nation. And it just may be that large multidisciplinary centers can afford to provide this service free of charge until reimbursement is established. As long as the hospital is profitable, it may also be possible to apply a portion of the free program costs toward a center’s community service benefit, which was a strong contributing factor for us. By bringing together experts at our institution from a variety of different disciplines and working together as a team, we were able to ensure that despite the free nature of our program, meticulous attention was paid to quality and safety. This is in fact the primary reason our senior administration endorsed the program……. I have been told they were most impressed by the opportunity to fulfill our hospital mission, which is to save lives, grow, demonstrate innovation, sustainability, and teamwork. The development of this program was an extraordinary multidisciplinary effort, which you will now hear about.

We have multiple scanners throughout our organization and were able to identify 30 slots for a pilot program to screen 30 patients per week. We had approval to use downtime after hours, bringing in an overtime team if necessary for potential overflow. We secured an easy to remember 800 line so patients could call directly for information, but we required that the test be ordered by the patient’s PCP. We developed an extensive, relational database to help manage the findings similar to our existing database in mammography, but set to the NCCN guidelines for follow-up recommendations and our structured reporting LUNG RADS system.

71Patient SurveyWe learned from our patient survey that most PCPs did not require a visit prior to ordering the test and patients were for the most part, pleased that they had been screened, especially those with a finding that required follow-up. There were a handful of calls to the program, for clarification of what that follow-up meant.

We presented our pilot to senior administration and have received approval to offer free LDCT screening for 5 years or until reimbursement is established.

We started with a multidisciplinary team and identified physician and administrator champions from representative areas of the organization to be part of a steering committee -which oversees the program and the education and awareness campaign that is associated with lung screening. We meet every 2 to 3 weeks and share group exchanges regarding any new information that becomes available to anyone on the team for the benefit of the whole group who then imparts such information to their respective disciplines. We focused the program to be evidence-based. We developed a comprehensive business plan based on the NLST experience to allow administration to become comfortable with the use of our CT scanners in this capacity. We enlisted our legal and compliance departments to give guidance regarding regulatory issues. We developed a comprehensive CME and community education plan, which we continue to unravel.We saw early on that there were several areas of concern to address in order for us to move forward. Among them were issues of informed consent, degree of PCP involvement, education regarding screening as a process, concern for enticement or hidden cost to the patient, particularly those who are uninsured, worry that we might overload the radiology department, PCPs , or specialists, the perception of outside hospitals and clinicians about our potential motives for free screening, and concern over what might happen if reimbursement is not established.

We decided to name the awareness movement Rescue Lung, Rescue Life because we want to draw a parallel to rescue situations. We want to create a sense of urgency similar to rescue efforts. Now that we know we can save tens of thousands of lives per year with screening, it seems appropriate that we do whatever we can to save them. IF we saw a burning building with 30,000 lives inside, we would go to great lengths, even risk our own well-being to save those lives. We must begin to think about the thousands who in the absence of CT screening will otherwise die from lung cancer in the same way. As you can see the steering committee consists of a large group of dedicated and committed professionals from all aspects of the hospital, many of whom took on additional job responsibilities just to make this program succeed. I am very proud to be a part of this group.

On the basis of our breast screening program, we were able to back out a sense of what our population numbers should be for our patient base. According to the NLST approximately 3% of the population would qualify for the high-risk group. We verified this number independently through CDC information. We estimate that approximately 4500 patients per year from our own patient base would screen

The database will track all recommended follow-up for the patients, and thus avoid the need for primary care to manage scheduling of follow-up studies, in the same way as mammography. We were able to reassure our PCPs with this approach. The development of a 4 page FAQ sheet, physician education materials, CME campaign, and selective marketing helped to alleviate concerns regarding informed consent, enticement concerns, and perception of outside facilities.7 potentially significant findingsAfter 2 years we will save 1 life every 3 weeks

We hope they hear our message of urgency and ask others to join us in our plea to encourage the task force to make this issue a priority given the potential for lost lives through inaction. Certainly, if we continue to screen for breast cancer, it is unavoidable……..LDCT lung screening will become a covered benefit because as a screening modality, the results are at least as favorable, if not more so than what we see with mammography almost across the board.If you offer to free lung screen, for compliance purposes, it must be free to everyone, even a patient whose insurer provides the benefit.
82Risks of Free Screening States where health insurance is not required by lawMassachusetts >98% insuredUS Population statistics – ~ <4% of high-risk patients will not have insuranceOperational endeavor – Instructional CDPotential for patient harm - Lung Cancer Alliance National Framework For ExcellenceNot all centers can offer free screening. Large multidisciplinary centers like ours with lung cancer centers of excellence should evaluate the possibility of offering free lung screening. We encourage all centers to look to develop low-cost efficient models of care delivery to make access to screening as equitable as possible during this period of transition. Massachusetts residents are required by law to have health insurance, and as such we could minimize concern for subsequent follow-up testing inherent to the screening process and the dilemma of how to fund treatment for any uninsured patient’s diagnosed with lung cancer via free screening. This issue would need to be assessed and addressed by individual health care facilities considering free screening. Uninsured patients with lung cancer will eventually present to the health care system at which time associated costs of treatment are considerable. Most facilities have mechanisms to assist in such situations ,which can perhaps be evaluated in the context of free lung screening. The number of uninsured patients in this age group who fit the tobacco profile required for free screening is actually quite low across the US likely less than 4% of the NLST group. We are developing a financial model whereby an individual center can input its community’s demographics, and diagnostic and treatment costs to estimate the potential amount necessary for a charitable organization to fund the costs of those uninsured patients participating in the program. As an example, a center whose community saw 10% of patients aged to be uninsured would need to be provide a mechanism for payment of lung cancer treatment for one uninsured patient for every 2000 patients screened. We are looking to share our lung screening experience and materials with interested parties through the development of an instructional CD. We are in the process of creating an electronic information package which contains the stripped database for tracking and reporting findings, our structured reporting LUNG RADS paperwork and system, FAQ sheets, CME presentations, and business analyses that can be used to develop a quality focused, evidence based lung screening program at other sites. Those interested should contact us so we can send you the materials when available. The goal is to minimize as much as possible the pain associated with the operational endeavor of starting a responsible, high volume, lung screening program. The Lung Cancer Alliance has issued their National Framework for Excellence which defines and sets expectations for responsible screening programs, because done without careful attention to guideline recommendations and without the support of a multidisciplinary team, there is potential for patient harm. The LCA website is a good resource for those developing a lung screening program.
