Stage IV non-small cell lung cancer in Veterans undergoing lung cancer screening who were not prescribed statins despite U.S. Preventative Services Task Force recommendations.

Abstract

e20583 Background: It is well established that Veterans eligible for lung cancer screening (LCS) are also at risk of atherosclerotic cardiovascular disease (ASCVD) due to smoking. Current concepts suggest that statins could play a role in lung cancer prevention and treatment. Accordingly, the purpose of this retrospective, quality improvement project was to determine whether newly diagnosed stage IV non-small cell lung cancer (NCSLC) rate is higher in Veterans undergoing LCS who were not prescribed statins despite U.S. Preventative Services Task Force (USPSTF) recommendations. Methods: Electronic health records of Veterans undergoing LCS and subsequently diagnosed with NSCLC at the Jesse Brown VA Medical Center, Chicago, Illinois between 2021 and 2023 were reviewed. In each case, pertinent demographic, clinical, pathological, and pharmacy data were retrieved. The American College of Cardiology’s ASCVD Risk Estimator was used to assess the Veteran’s 10-year risk for a first ASCVD event. Data are presented as means ± SD. Statistical analysis was performed using Student’s t- and chi-squared tests as indicated. P < 0.05 was considered statistically significant. Results: Out of 57 Veterans diagnosed NSCLC, 33 (all males; 71±6 years; 28 African Americans) were prescribed and 24 (21 males, 3 females; 70±7 years; 18 African Americans) were not prescribed statins. Body mass index was similar in both groups (26.6±6.0 and 26.0±6.0 kg/m2, respectively; p = 0.73). Twenty one out of 24 Veterans (88%) not prescribed statins were eligible according to USPSTF recommendations (10-year calculated risk, 15.23%±6.9%). Stage IV NSCLC was diagnosed in 7/33 (21%) Veterans prescribed statins and in 10/21 (48%) USPSTF-eligible Veterans not prescribed statins (p < 0.05). Conclusions: Clinicians should assess the needfor a statin for primary prevention of ASCVD in each Veteran undergoing LCS. Stage IV NSCLC is more prevalent in Veterans with ASCVD risk who were not prescribed statins despite USPSTF recommendations. A larger, multi-site study is warranted to support or refute these initial observations.
