Introduction: Lung cancer screening is underutilized, especially in rural areas where lung cancer mortality is high. Approximately 11.2% of the United States (US) population over age 50 meet the United States Preventive Services Task Force (USPSTF) 2021 lung cancer screening eligibility criteria; the proportion of eligible Veterans is unknown. This study evaluated the proportion of Veterans who are USPSTF-eligible and tested the hypothesis that more USPSTF-2021-eligible Veterans reside in rural versus non-rural areas.

Methods: Investigators cross-sectionally surveyed a national sample of Veterans age 50 years and older January-November 2022. Oversampling ensured inclusion of minority groups and accounted for geographic variation in tobacco use. Analyses in 2023-2024 evaluated the proportion of USPSTF-eligible Veterans by year (2013 and 2021) and tested USPSTF-2021 eligibility by rural status (rural vs non-rural) using Chi square tests. Weighting accounted for survey non-response and applied results to the whole Veteran population in a sensitivity analysis.

Results: Of 2,000 surveyed, 754 responded (37.7% response rate); most respondents were White (74.4%), male (92.6%), resided in non-rural areas (66.0%). Proportions meeting USPSTF criteria were 35.5% (95% CI 31.6-39.6%) in 2021 and 27.8% (95%CI 24.3-31.7%) in 2013. The proportion of USPSTF-2021-eligible rural Veterans (41.2%;95%CI 34.8-48.0%) was higher compared with non-rural (32.5%;95% CI 27.7-37.7%), P=0.037. A sensitivity analysis found the proportion of Veterans USPSTF-2021-eligible in the whole population was 33.0%.

Conclusions: The proportion of Veterans USPSTF-2021-eligible was nearly three times higher than the general US population (11.2%), and a greater proportion of eligible Veterans resided in rural compared with non-rural areas. These findings are critical for policies aimed at fully implementing lung cancer screening at scale.

Background: Several head-to-head meta-analyses have compared the efficacy and safety of different first-line treatments in patients with EGFR mutation-positive (M+) advanced or metastatic non-squamous non-small cell lung cancer (nsq-NSCLC). However, there is a lack of comprehensive evaluation encompassing multiple treatment strategies. Our objective is to conduct a network meta-analysis that includes various treatment modalities, enabling both direct and indirect comparisons for a more thorough assessment.

Background: Rearranged during transfection () fusions represent a distinct molecular subset of non-small cell lung cancer (NSCLC) with targeted therapeutic potential. Selpercatinib, a highly selective inhibitor, has demonstrated efficacy in various solid tumors harboring alterations. Here, we present a case highlighting the use and clinical outcomes of selpercatinib in a patient diagnosed with advanced lung adenocarcinoma harboring a fusion.

Introduction: Cigarette smoking is an important risk factor in the development of dyspnea. Programs designed to strengthen the respiratory muscles can improve dyspnea in people with or without lung disease. As a first step in understanding the feasibility of offering a respiratory muscle training (RMT) program to people who are seeking help to try to quit smoking, we asked callers who contacted the New York State Quitline about their dyspnea and potential interest in a home-based RMT program.
