1. BACKGROUND: Induction chemoradiotherapy (CRT) followed by surgery is a therapeutic option for locally advanced non-small cell lung cancer (LA-NSCLC). Pubmed BACKGROUND: Induction chemoradiotherapy (CRT) followed by surgery is a therapeutic option for locally advanced non-small cell lung cancer (LA-NSCLC). Typically, around 40-50 Gy of radiation is applied as the induction-dose; however, a definitive-dose (DD) of radiation (60 Gy or higher) is occasionally applied to increase local control. We investigated the impact of induction CRT with DD radiation in LA-NSCLC patients treated with a single regimen of docetaxel and cisplatin. METHODS: We reviewed 110 patients with LA-NSCLC who underwent induction CRT followed by surgery using a single regimen (docetaxel and cisplatin) between January 1999 and December 2014 at our hospital. The clinical outcomes of a DD group (60 Gy or higher, n=11) and a non-DD group (less than 60 Gy, n=99) were investigated using a propensity score (PS)-matched analysis. RESULTS: An advanced clinical stage was significantly more common in the DD group than in the non-DD group (P=0.033). Before and after the PS-matching based on seven factors including clinical stage, there was no significant difference in the rates of postoperative (PO) complication, mortality, 5-year overall survival (OS), or 5-year recurrence-free survival (RFS) between the two groups. After the PS-matching, the pathological complete response (CR) rate was significantly higher in the DD group than in the non-DD group [50% (n=5/10) vs. 0% (n=0/10), P=0.033]. CONCLUSIONS: Induction CRT followed by surgery using docetaxel and cisplatin with DD radiation can be performed safely and is associated with a higher pathological CR rate than that attained using non-DD radiation in LA-NSCLC patients.
