Patients were screened at 1 of 10 participating community-based centers within a 22-hospital system from 2013 to 2015. LDCT examinations were interpreted by 1 of 20 radiologists using structured reporting and an internally developed tracking system. Manual chart review was performed to ascertain the malignancy detection rate.
A total of 357 patients were screened with LDCT. Of these, 80 patients were ineligible and 3 declined enrollment. The remaining 274 patients satisfied accepted screening criteria and were enrolled in the program. Malignancy was detected in a total of 11 enrollees (4.0%), 8 with lung cancer and 3 with extrapulmonary primary malignancies. Three patients (1.1%) were diagnosed with early-stage lung cancer and received definitive therapy.
Early-stage lung cancer was detected with LDCT screening in an integrated community health system at a rate similar to other trials.
