Phase I study of concurrent selective lymph node late course accelerated hyper-fractionated radiotherapy and Capecitabine, Cisplatin for locally advanced esophageal squamous cell carcinoma

Twelve patients with locally advanced esophageal squamous cell carcinoma were enrolled to evaluate the safety and efficacy of concurrent chemo-radiotherapy. Dose-limiting toxicity was mainly observed at Capecitabine 1500 mg. The maximum-tolerated dose/recommended dose of Capecitabine was 1000 mg. The Kaplan–Meier estimated overall l-year survival rate was 100%.
