Abstract:
BACKGROUND:Shared decision-making is an essential element of low-dose CT (LDCT) screening for lung cancer. Understanding patient-level outcomes from the National Lung Screening Trial (NLST) is critical to effectively communicate risks and benefits of screening to patients. METHODS:We performed a secondary analysis of data collected in the NLST. We determined outcomes of each LDCT scan performed in the NLST (downstream evaluation, complications, lung cancer diagnoses), and compared outcomes at the test level with outcomes calculated at the patient level for those randomized to LDCT screening. To assess the impact of COPD on patient outcomes, we compared outcomes among patients with and without COPD. RESULTS:Of 75,138 LDCT scans, 14.2% led to a diagnostic study and 1.5% to an invasive procedure, with 0.3% of LDCT scans resulting in a procedure-related complication and 0.1% in a serious complication. Among 24,453 patients who underwent LDCT screening, 30.5% underwent a diagnostic study and 4.2% an invasive procedure, with 0.9% of screened patients experiencing a procedure-related complication and 0.3% a serious complication. Patients with COPD (defined by self-report) were more likely to need a diagnostic study (adjusted OR [aOR], 1.29; P < .01) and an invasive procedure (aOR, 1.41; P < .01) and more likely to experience a complication (aOR, 1.83; P < .01) and a serious complication (aOR, 1.78; P = .01). Patients with COPD also were more likely to be diagnosed with lung cancer (aOR, 1.43; P < .01). CONCLUSIONS:We provide important patient-level data from the NLST that can be used to guide shared decision-making. The risk-to-benefit ratio of screening may vary significantly in some patients, such as those with COPD, in whom both risks and benefits of screening may be increased.
