Ineligibility for the PACIFIC trial in unresectable stage III non-small cell lung cancer patients

Purpose Recently, based on results of the PACIFIC trial, durvalumab after chemoradiotherapy (CRT) became the standard therapy for unresectable stage III non-small cell lung cancer (NSCLC). However, in the PACIFIC trial, patients were recruited and randomized after CRT, and certain patients were considered ineligible after CRT in the real world. No study has been conducted on the patients who were ineligible for the PACIFIC trial, and hence, we conducted a retrospective study on them.
