Current Recommendations for Lung Cancer Screening

Summary of Current Guidelines CMS Primary Criteria 55 – 79 years > 30 pack-yrs 55 – 74 years > 30 pack-yrs Current smoker or quit < 15 yrs Asymptomatic 55 – 80 years > 30 pack-yrs Current smoker or quit < 15 yrs Asymptomatic 55 – 77 years > 30 pack-yrs Current smoker or quit < 15 yrs Asymptomatic Secondary Criteria Lung cancer survivor > 50 years > 20 pack-yrs AND Added >5% risk of lung CA within 5 years > 50 years > 20 pack-yrs At least one other risk factor (not second-hand smoke) None None Grade B Recommendation

CMS: Additional Requirements Must be performed at specialized centers – Radiology imaging center with appropriate expertise, equipment – Must collect and submit data to a CMS-approved national registry Registries ?? APPROVEDApplication In Progress

Initial LDCT must be ordered during a lung cancer screening counseling and shared decision making visit Documentation 1.Eligibility Criteria are all met and documented 2.One or more decision aids to discuss benefits, harms, follow-up diagnostic testing, over-diagnosis, false positive rate, total radiation exposure 3.Counseling on importance of adherence to annual LDCT screening, impact of comorbidities, willingness to undergo diagnosis and/or treatment 4.Counseling on smoking cessation (or continued abstinence), including offering additional tobacco cessation counseling services if appropriate CMS: Additional Requirements

Lung Cancer Screening in Practice

Multidisciplinary program – Communication is key – Include PMDs “Real time” scan and consultation – Shared decision making – NCCN Guidelines – Smoking cessation counseling Referral for incidental findings Lung Cancer Screening Program

Patient/PMD call for or order lung cancer screening Chest Radiology Thoracic Surgeon NP/CTTS Workflow Eligibility confirmed Screening clinic appointment made

Developed by leadership of ACCP/ATS Endorsed by AATS, American Cancer Society, ASCO Describes 9 essential components / 21 policy statements – Who is offered screening, and for how long – Technical aspects of LDCT scans – Interpretation of scans / definition of “positive” – Standardized reporting – Management algorithms – Patient and provider education – Data collection – Smoking cessation

Smoking Cessation

Rationale for Including Tobacco Cessation Counseling with LCS Decreases risk of lung cancer and other smoking-related conditions Increases cost effectiveness of lung cancer screening It is the right thing to do Required by CMS for reimbursement

Estimated mean life-years, QALYs, costs per person, ICERs Used 3 alternative strategies – Screening with LDCT – Screening with radiography – No screening Conclusions – LDCT cost $81,000 / QALY gained – Caveat: “modest changes” in assumptions would greatly alter results

Modeling used to estimate QALYs saved by lung cancer screening and treatment Included cost of “intensive” cessation programs – Generic NRT vs. buproprion vs. varenicline Hypothetical cohort yo with > 30 p-y smoking – 2/3 current smokers – 1/3 former smokers

Medical Oncology Radiation Oncology Chest Radiology Thoracic Surgery Local/Referri ng Physicians Smoking Cessation Lung Cancer Screening Program Lung Cancer Screening and Management: A Multidisciplinary Effort

Current Challenges Logistics – Protocoling for scans – Insurers slow to get on point – Standardized reporting Access for un- and underinsured Referring providers – Appropriate referrals for screening – Follow-up after initial screening study

Getting “Buy In” Multidisciplinary team approach includes Primary Care, General Medicine and Pulmonary Provider Education – Teaching Conferences/Grand Rounds – Community outreach – Electronic alerts and reminders in EMR

Role of the EMR in Screening BPAs for primary care providers Direct access to patients – Electronic reminders (e.g. MyChart) – Reminder letter sent via mail – Pop-up message at check-in kiosk “Hard stops” to ensure clinical eligibility during ordering process Smoking cessation materials and resources Decision aid

So What Happens Next? Improving existing screening and diagnostic modalities to increase precision and reduce risk – Non-invasive prediction models – Safer practices Adjunctive testing – Biomarkers

Reducing Risk in Lung Cancer Screening

24.2% of CT screens were positive NLST- False Positives

NLST- Positive Studies 92% of positive CT screens had a diagnostic evaluation  16 deaths within 60 days  6 of 16 had benign pathology 8.4%

Overdiagnosis: Detection of disease that does not contribute to death Results in unnecessary treatment, morbidity, cost, worry

New Technology Improved precision of TBBx, VATS wedge In lieu of diagnostic VATS?

Summary Screening with LDCT is here, and Thoracic Surgeons are important members of the LCS Team Lung cancer screening programs – Multidisciplinary collaboration – Must include smoking cessation There is still room for improvement – Better and more tools for accurate prediction – Safer procedures
