Brief Summary

This project intends to study the efficacy and safety of camrelizumab combined with chemotherapy followed by radiotherapy in the perioperative treatment of AEG.

Detailed Description

The incidence of Adenocarcinoma of esophagogastric junction (AEG) is increasing in recent years. According to the statistics of The National Cancer Center of Japan, the proportion of AEG in gastric adenocarcinoma increased from 2.3% in the middle of the 20th century to 10.3% in the beginning of this century, and the proportion of Siewert II in AEG increased from 28.5% to 57.3%. Due to the special biological characteristics of tumor in this region, its definition and surgical treatment principles are controversial.

For AEG, the clinical study results of neoadjuvant chemoradiotherapy + surgery + chemotherapy showed that the tumor stage could be reduced, R0 resection could be improved and overall survival could be improved, without increasing postoperative complications and mortality. Long-term follow-up results from the German TRIAL III of preoperative chemoradiotherapy for AEG (POET) showed that preoperative chemoradiotherapy reduced recurrence (5y-local recurrence: 21% vs. 38%) and prolonged survival (3y-OS: 46.7% vs. 26.1%), without a significant increase in treatment toxicity and perioperative complications . Although some patients with AEG were included in the resolve 、 prodigy and resolution study ,and the total population could benefit from postoperative adjuvant radiotherapy and chemotherapy, but it was uncertain whether the patients with AEG could benefit in Asia.

Therefore, this project intends to study the efficacy and safety of camrelizumab combined with chemotherapy followed by radiotherapy in the perioperative treatment of AEG.
