A Trial of CMNa Combined With Preoperatie Concurrent Chemoradiotherapy for Locally Advanced ESCC

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

Detailed Description
-----------------
The primary end ponit of this study is pathological complete response.And the primary hypothesis is the CMNa will improve patholofical response rate and thus improve OS、DFS. Assuming bilateral a=0.05, statistical power of 80%.The total sample size is 40 cases.

Esophageal Neoplasms

Intervention / Treatment

* Drug: Sodium Glycididazole


Participation Criteria

Eligibility Criteria
-----------------
Inclusion Criteria: Signed written informed consent prior to study entry Patients with ESCC in thoracic segment which is resectable（T2-3，N0-1，M0） confirmed by imaging and pathology or cytology; Patients have tumor lesions which can be objectively measured ,the length of tumor:≤8cm, the width of tumor:≤5cm;If the tumor cross the GEJ and violate the proximal stomach, the tumor must include esophagus and GEJ. The tumor is less than 2cm of the stomach Not infringe bronchial wall; no esophagus-tracheal fistula. normal bone marrow reserve: ANCcount ≥1500/mm3;platelet count ≥100,000/mm3,hemoglobin≥9g/dl normal hepatic funcion:bilirubin level ≤1.5×ULN;AST/ALT≤1.5×ULN normal renal function: serum creatinine≤1.5mg/dl and calculated creatinine clearance ≥60ml/min normal cardiac function ECOG PS of 0 or 1 Expected lifetime≥3 months Subjects tumor tissue available for the relevant biomarker detection Exclusion Criteria: Female subject who is during pregnancy or lactation, and the subject who have fertility don't take effective contraception during study. Any mental illness or nervous system lesions or can't tell treatment response clearly (such as cerebrovascular accident sequelae) Any serious uncontrolled disease and infection, such as severe heart, liver, kidney diseases or diabetes, can't complete the treatment plan Patients who have other malignant lesions, except curable skin cancer (non- melanoma skin cancer),carcinoma in situ of cervix or serve disease cured for 5 years Primary lesions were multifocal Patients with distant metastasis. A small amount of stomach tumor violate GEJ or the distal esophageal. Patients who have obvious esophageal ulcers or have above moderate pains in chest-back or have symptoms of esophageal perforation received anti-cancer treatment of esophageal cancer before the group, including surgery, radiotherapy, chemotherapy (induction of chemotherapy before the group is greater than or equal to two cycles). Cervical esophageal cancer confirmed by iconography Not esophageal squamous carcinoma confirmed by pathology or cytology History of active hepatitis
