Definitive Chemoradiotherapy with Capecitabine and Cisplatin in Patients with Esophageal Cancer: A Pilot Study

ABSTRACT

We aimed to evaluate the feasibility of concurrent chemoradiotherapy (CRT) with capecitabine and cisplatin in patients with squamous cell carcinoma of the esophagus. Eighteen patients with esophageal cancer were enrolled on the study. The chemotherapy during CRT consisted of two cycles of intravenous cisplatin of 60 mg/ m2 on day 1 and oral capecitabine 825 mg/m2 twice daily from day 1 to 14 at 3-week intervals. The radiotherapy (2.0 Gy fraction/day to a total dose of 60 Gy) was delivered to the primary tumor site and regional lymph node. After concurrent CRT, 2 cycles of capecitabine (1,000 mg/m2 b.i.d from days 1 to 14) plus cisplatin (60 mg/m2 on day 1) were added every 3 weeks. All patients completed the planned treatment. After the chemoradiotherapy, 12 complete responses (CR, 66.7%) and 6 partial responses (PR, 33.3%) were confirmed. Grade 3 or 4 neutropenia only occurred in 2 patients, plus no treatment-related death was observed. At a median follow-up duration of 14.9 months, the estimated overall survival and progression-free survival rate at 2-yr was 70.7% and 54.4%, respectively. Concurrent CRT with capecitabine and cisplatin was found to be well-tolerated and effective in patients with esophageal cancer.
