Abstract
BACKGROUND: The therapeutic effect and side effect of neoadjuvant chemotherapy were still disputing issues when applied to resectable IIIa stage non-small cell lung cancer (NSCLC) patients. The retrospective analysis was aimed to investigate the short-term efficacy and postoperative complications in resectable IIIa NSCLC patients treated with neoadjuvant chemotherapy.Entities:
