About

The purpose of this study is to observe and evaluate the efficacy and safety of SHR-1210 for adjuvant treatment of resectable esophageal squamous cell carcinoma

Full description

Although esophagectomy is still the standard treatment for patients with localized esophageal cancer, the long-term therapeutic effect is not satisfactory.About 50% of patients experienced relapse in the first year after treatment. The 5-year survival rate of esophageal cancer patients treated by surgery is still less than 30%. Although the effect of preoperative treatment is relatively clear, the effect of postoperative treatment, especially postoperative chemotherapy, is still controversial and no consensus has been reached.The basic reason is that the postoperative trauma of esophageal cancer is large, and the patients' tolerance to chemotherapy is poor. The efficacy of immunocheckpoint inhibitors in metastatic ESCC has been recognized.We plan to conduct a phase II multicenter, single arm, open phase II clinical trial to evaluate the efficacy and safety of humanized anti PD-1 monoclonal antibody SHR-1210 in adjuvant treatment of resectable esophageal squamous cell carcinoma.
