Objective:The aim of this study is to investigate the outcomes of induction chemoradiotherapy (ICRT) followed by surgery in patients with non-small cell lung cancer (NSCLC).

Methods:We retrospectively analyzed consecutive patients with NSCLC who underwent ICRT followed by surgery at our hospital between January 2006 and December 2015.

Results:A total of 102 patients were eligible for evaluation (cStage/ⅠB/ⅡA/ⅡB/ⅢA/ⅢB, 1/8/14/75/4). The median age was 66 years. Forty-one patients had adenocarcinoma, 42 patients had squamous cell carcinoma, and 19 patients had others. The regimen consisted of carboplatin and paclitaxel in 94 patients, and the others in 8 patients plus concurrent radiation at a dose of 28 Gy in 1 patient, 30 Gy in 28 patients, 40 Gy in 42 patients, 45 Gy in 3 patients, and 50 Gy in 28 patients. Major response was obtained in 84 patients. Grade 3/4 toxicity of ICRT reported in 57 patients. The 5-year relapse-free and overall survival rate was 51.4% and 62.7%, respectively.

Conclusion:ICRT (carboplatin and paclitaxel plus concurrent standard radiation) followed by surgery in NSCLC can be safely performed and may contribute to satisfactory outcomes in locally advanced NSCLC. It is likely that 28~50 Gy radiation dose contributes to satisfactory outcomes in ICRT.
