Evaluation of the feasibility and efficacy of neoadjuvant concurrent chemoradiotherapy (CRT) with capecitabine and oxaliplatin in patients with locally advanced esophageal cancer. Forty-two patients were eligible for the study. The chemotherapy during CRT consisted of two cycles of intravenous oxaliplatin of 120 mg/m(2) on day 1 and oral capecitabine 825 mg/m(2) twice daily on days 1-14 at 3-week intervals. The radiotherapy (1.8 Gy/fraction/day to a total dose of 45 Gy) was delivered to the primary tumor site and regional lymph node. All patients completed the planned treatment. Overall clinical response rate was 54.8% with complete response in 16.7% while pathological response rate was 38%. Anemia was the commonest hematologic toxicity (52.3%) with grade 3 in 4.7%, and esophagitis was the commonest non-hematologic toxicity 59.5% with grade 3 and 4 in 9.5%. No treatment-related death was observed. After a median follow-up duration of 19 months, the 2-year survival rate was 42%, median survival time was 20 months (95%CI: 13.802-26.198), while 2-year progression-free survival (PFS) rate was 32.5% with median PFS time of 15 months (95%CI: 10.042-19.958). Neoadjuvant concurrent CRT with capecitabine and oxaliplatin was found to be well tolerated and effective in patients with locally advanced esophageal cancer; however, these results should be further evaluated in a phase III study.
