About

China is a country with a large incidence of esophageal cancer. The prevalence and mortality rate of esophageal cancer in China ranks fifth in the world. However, due to China's huge population base, new patients with esophageal cancer and deaths account for about 55% of the world. This study aimed to explore the efficacy and safety of Camrelizumab Combined With Concurrent Radiotherapy and Chemotherapy for Treatment of Patients With Local Recurrence of Esophageal Cancer.

Full description

This is an open clinical study to evaluate the efficacy and safety of Camrelizumab combined with Concurrent Radiotherapy and Chemotherapy in the treatment of locally recurrent esophageal cancer.

Objective to study patients with local recurrence of esophageal cancer after radical treatment.

The study will take progression free survival (PFS) as the main efficacy index, and plan to enroll about 62 patients with local recurrence of esophageal cancer after radical treatment. After fully informed and signed the informed consent, the subjects will enter the experimental stage after screening.
