Core Tip
Core Tip: Immunotherapy is reshaping the treatment landscape for resectable gastric and gastroesophageal junction cancers. Despite the established benefit of perioperative leucovorin, oxaliplatin, and docetaxel chemotherapy, complete pathological response rates remain below 15%. Recent phase III trials, including KEYNOTE-585 with pembrolizumab and MATTERHORN with durvalumab, have demonstrated improved pathological responses and event-free survival, particularly in biomarker-enriched subgroups such as microsatellite instability-high or programmed death-ligand 1-positive tumors. This article summarizes the evolving evidence supporting immune checkpoint inhibitors in the perioperative setting and highlights future directions toward biomarker-driven, personalized multimodal therapy for gastric cancer.
