[Progress and prospects of international cancer drug clinical research on gastric cancer].

Gastric cancer is a common type of malignant tumor. Recently, a growing number of clinical researches initiated by investigators have provided valuable evidence for clinical practice. Here we review the perioperative treatment of locally advanced gastric cancer, and summarize the optimization of neoadjuvant treatment regimens, the exploration of new combinational treatment models and new adjuvant chemotherapy schemes, and the changes in the status of chemoradiotherapy in adjuvant therapy. At the same time, for the comprehensive treatment of advanced gastric cancer, the advances in the optimization of first-line chemotherapy regimens, emerging immunotherapy and targeted therapy are reviewed as well. Gastric cancer is a highly heterogeneous tumor. For further development of precision medicine represented by targeted therapy and immunotherapy, genetic testing-guided precise molecular subtyping will be the direction.
