Retrospect of 2019: focus on the research progress of gastric neoplasm / 中华胃肠外科杂志

ABSTRACT

Gastric carcinoma, gastrointestinal stromal tumor and gastric neuroendocrine tumor are the most common gastric neoplasms. A series of researches in 2019 showed that the safety and efficacy of laparoscopic gastrectomy in the treatment of both early and advanced gastric cancer patients are similar to open surgeries, providing a high-level evidence-based medical basis for the promotion of laparoscopic surgery in the treatment for gastric cancer. In multidisciplinary treatment and perioperative chemoradiotherapy, major research results have also been published, and clinical researches in China are gradually gaining international recognition and attention. Although the application of targeted therapy and immunotherapy has made progress, the first-line therapy after gastric cancer surgery has not been established. In the field of gastrointestinal stromal tumors, laparoscopic surgery has gradually been recognized, and surgical treatment of patients with advanced drug resistance still has its value. In terms of gastric neuroendocrine tumors, the latest researches showed that surgical methods should be selected according to tumor characteristics, and gastric adenocarcinoma with neuroendocrine components may have a worse prognosis.
