Core Tip
Core Tip: Immune checkpoint inhibitors gigantically expand the methods of immunotherapy and bring a glimmer of hopefulness for patients with advanced gastric cancer (GC). Ongoing clinical trials show that the effect of monotherapy was not satisfactory, while the combination therapy manifested a better response rate. The most recent clinical trial results of GC immunotherapy are reviewed to suggest the reasons and mechanisms of the high response rate. Additionally, we propose the potential problems of these trials and speculate on the benefits of immune checkpoint inhibitors in neoadjuvant therapy.
