RESUMEN
BACKGROUND: Lung cancer screening (LCS) with low-dose computed tomography (LDCT) decreases lung cancer mortality; however, screening benefits and harms are poorly described in minority populations. Our purpose is to report benefits and harms of LCS implemented in a safety-net institution. Because harms are rare, there is a paucity of clinical experience guiding shared decision making (SDM) with diverse populations. METHODS: We conducted a prospective, observational study of patients undergoing LCS between September 2014 and March 2019 with 2-year follow-up. LDCT results, lung cancer diagnosis, stage, treatment, false-positive results, false-negative procedure from a false-positive result, complication from procedures, and death were recorded. Patient cases highlighting the challenges of delivering LCS to an underserved population were evaluated in the context of current evidence. RESULTS: Among the 995 patients who underwent screening, 54.9% were African American, with 2.9% receiving a cancer diagnosis, a false-positive rate of 9.4% and a 0.7% rate of procedures resulting from a false-positive result. Five patient cases highlight challenges, namely (1) false-positive result resulting in operation, (2) false-negative result, (3) incidental finding, (4) delay in diagnosis, and (5) death from cause other than lung cancer. CONCLUSIONS: LCS of a predominantly African American population with 2-year follow-up demonstrates early detection and treatment of lung cancer with few harms. Although rare, harms must be clearly described with population-specific evidence. We report clinical perspective of rare harms that can provide guidance to providers and patients.
