This document summarizes a study on the 5-year survival of non-small cell lung cancer patients after adjuvant chemoimmunoradiotherapy compared to surgery alone or postoperative radiotherapy. The study found that adjuvant chemoimmunoradiotherapy significantly improved 5-year survival and lifespan for patients with lymph node metastases (N1-2) compared to the other treatments. However, for patients without lymph node metastases (N0), the 5-year survival was not significantly different between adjuvant chemoimmunoradiotherapy and surgery alone or postoperative radiotherapy.
