A Trial of CMNa Combined With Concurrent Chemoradiotherapy for Locally Recurrent ESCC

Study Overview
=================
Brief Summary
-----------------
This is a perspective, multicenter,single arm, open study to evaluate the efficacy and safety of treatment with CMNa combined with concurrent chemoradiotherapy in patients with locally recurrent squamous cell esophageal carcinoma . Analyses of primary objective (ORR) will be done as defined in the protocol.

Detailed Description
-----------------
The primary end point of this study is objective response rate.The secondary end point is OS, PFS and the safety of drug. The primary hypothesis is the CMNa will improve ORR and thus improve OS, PFS. Assuming bilateral a=0.05, statistical power of 80%. The total sample size is 40 cases.
