Abstract

Objectives: Lung cancer screening with low dose computed-tomography (LDCT) is currently recommended for high-risk populations based on mortality benefit shown in the National Lung Screening Trial (NLST). This study evaluated performance of a community-based lung cancer screening program in a Histoplasma endemic region. Materials and Methods: Demographic and clinical information was collected through retrospective review of patients in the Lung Cancer Screening program of a Kentucky (Histoplasma endemic region) health system from 2016 and 2017. A positive LDCT screen is defined as Lung-RADS version 1.0 assessment categories 3 or 4. Patients characteristics, initial screening results and follow up were analyzed and compared to NLST results. Results: A total of 4500 LDCT screens were performed in 2016 (39%) and 2017 (61%) with 43% adherence rate to repeat annual screen in 2017. Mean age of patients was 64 years, with majority being females (54%) and current smokers (69%) with average 52-pack year smoking history. The rate of positive LDCT was 13.3% (600) varying based on baseline (14.6%) and annual (9.5%) screen. A total of 70 lung cancers were diagnosed among all positive LDCT screens (11.7%) with a false positive rate of 12%. Conclusions: Baseline positive screens in our study are similar to NLST data with Lung-RADS criteria implementation (14.6% vs 13.6%, p = 0.15) despite being a Histoplasma endemic region. Our study shows a successful performance of a community-based lung cancer screening program in a Histoplasma endemic region.
