Abstract: On March 15th 2025, the Japan Gastric Cancer Association released the 7th edition of Japanese Gastric Cancer Treatment Guidelines. New clinical questions were raised and updated in laparoscopic surgery for gastric cancer, functional preservation surgery and extended surgery, perioperative chemotherapy, chemotherapy based on biomarkers, long-term complications after gastrectomy, treatment strategies for the elderly and palliative treatment methods. In particular, the recommendation of laparoscopic total gastrectomy and minimally invasive surgery for esophagogastric junction cancer has been further clarified and improved. In terms of function preserving gastrectomy, a new surgical method of subtotal gastrectomy has been proposed. However, there is still a lack of clear recommendations in perioperative treatment and conversion therapy. From the application of biomarker detection means and the emergence of new targeted drugs, to the attention to the strategies of surgical, endoscopic and chemotherapy protocols for elderly patients with gastric cancer, all reflect the ideas of accurate diagnosis and treatment of gastric cancer and individualized treatment, while the attention paid to postoperative long-term complications indicates the pursuit of long-term survival and quality of life for patients.
