For many years, surgery alone was the standard treatment for patients with stage I-IIIA non-small-cell lung cancer (NSCLC). However, recent studies have demonstrated that adjuvant chemotherapy provides a survival benefit. The first adjuvant chemotherapy for NSCLC was performed in the 1960s using a key drug known as cyclophosphamide. ⋯ The Japan Lung Cancer Research Group (JLCRG) on Postsurgical Adjuvant Chemotherapy reported a 5-year overall survival advantage of 11% in the uracil-tegafur group patients with stage IB cancer. The efficacy of adjuvant chemotherapy with uracil-tegafur was confirmed in a meta-analysis. In conclusion, the results of phase III trials and a meta-analysis have confirmed the benefit of adjuvant chemotherapy for resected stage IB, II, and IIIA NSCLC.
