The purpose of this study is to investigate the safety and efficacy of Camrelizumab combined with paclitaxel (albumin binding type) and S-1 for first-line treatment of advanced gastric cancer, and to further explore the curative effect of PD - L1 expression in tumor tissue, EBV virus content, microsatellite instability (MSI), DNA mismatch repair (MMR), tumor mutation load (TMB), lymphocyte subgroup and cytokines.


Gastric cancer is a common malignant tumor of digestive tract.The incidence of gastric cancer in China accounts for about half of the world's total, the incidence rate ranks second, and the mortality rate ranks second.Moreover, the proportion of early gastric cancer in China is very low, only about 20%. Most of them are in advanced stage at the time of discovery. The overall 5-year survival rate is less than 15%, which seriously threatens the health and life of Chinese people.For nearly 90% of HER2 negative patients with advanced gastric and gastroesophageal junction adenocarcinoma (g / GEJ), the current first-line treatment option is chemotherapy, and the efficacy of available drugs is very limited.The ORR of the first-line chemotherapy is about 40%, and the OS is about 10 months. New therapeutic drugs are urgently needed to improve the efficacy of advanced G/GEJ.The purpose of this study was to investigate the safety and efficacy of Camrelizumab combined with paclitaxel (albumin binding type) and S-1 for first-line treatment of advanced gastric cancer.
