Esophageal cancer is still a serious threat to human life and health. China in particular. Relapse and metastasis are important causes of treatment failure. Immunotherapy is a new treatment method, which can be used in combination with chemotherapy to improve the therapeutic effect. However, the role of immunotherapy combined with chemoradiotherapy in concurrent chemoradiotherapy of recurrent esophageal cancer has not been clearly studied. Our team will study it in detail. The purpose of this study was to compare and analyze the effect of Camrelizumab in concurrent chemoradiotherapy of locally recurrent esophageal cancer.
