Abstract

Gastric cancer (GC) metastasis is the main cause of poor prognosis for GC patients. In recent years, breakthroughs in immunotherapy have been made in the treatment of many kinds of cancers, providing new hope for patients with GC metastasis. This paper reviews the mechanism of immunotherapy in GC metastasis and its clinical application, and discusses and compares the research and efficacy of immunotherapy in patients with liver metastasis, lung metastasis, peritoneal metastasis and lymph node metastasis of GC. This study explores the challenges and future development directions of immunotherapy, and provides a theoretical basis and clinical guidance for the precise treatment of patients with GC metastasis.

Keywords: Gastric cancer; Metastasis; Immunotherapy; Liver metastasis; Lung metastasis; Peritoneal metastasis

Core Tip: Immunotherapy has gradually begun to be applied in the treatment of gastric cancer (GC) metastasis. Some studies have shown that liver metastases of advanced GC have a reduced immune response rate due to the presence of hepatic immune tolerance mechanisms. Therefore, the mechanism and efficacy of immunotherapy applied in other metastases are discussed. Previous studies have shown that immunotherapy has the best efficacy for lung metastasis and the worst efficacy for peritoneal metastasis, but it has a good safety profile and is promising for use in all GC metastases.
