Toripalimab Plus FLOT in Locally Advanced Gastric Cancer

• Status: Not yet recruiting
• Trial end date: 2025-05-11
• Target enrollment: 0
• Participant gender: All

Summary

Neoadjuvant therapy for locally advanced gastric cancer is still in the exploratory stage. With the emergence of immune checkpoint inhibitors, neoadjuvant chemoimmunotherapy is also in the exploratory stage in locally advanced gastric cancer. At present, chemotherapy combined with immunotherapy is usually a simple combination of chemotherapeutic drugs and immune drugs, without taking into account of the influenece of applied sequence. The purpose of this study is to explore whether the sequence of chemotherapy and immunotherapy influence the complete pathological response rate in locally advanced gastric cancer.
