Concurrent chemoradiotherapy (CHRT) is the standard of care for unresectable locally advanced stage III non-small cell lung cancer. However, the optimal combination remains unclear. The aim of this study is to evaluate the efficacy of 2 induction chemotherapy cycles (days 1 and 22) with docetaxel 75 mg/m2 and cisplatin 75 mg/m2 followed by concurrent chemotherapy (weekly docetaxel-cisplatin, 20 mg/m2) and 3-D conformal radiotherapy for 6 weeks (66 Gy/5 fractions per week/2 Gy per fraction). ). The primary endpoint is the response rate. Secondary objectives are toxicity, time to progression, and overall survival.
