摘要：

2026年3月4日至6日，第98届日本胃癌学会年会于冲绳召开，会议对第16版《胃癌处理规约》进行了更新。新版规约围绕食管胃结合部癌诊疗、标本处理、病理分型、浸润分期、转移评估等多个核心维度完成修订，新增食管胃结合部区域定义及相关癌种的标准化记录方法，优化内镜切除标本的处理流程与评估标准，引入T_is分期并重构胃壁浸润深度（T）分类体系，完善淋巴结及远处转移的亚分类标准，同时补充药物与放射治疗相关的评估规范。本次修订统一了胃癌病理诊断与临床诊疗的标准，适配基因组学医疗发展需求，为胃癌精准诊疗提供了更具实操性的依据，也为胃癌领域的国际交流与研究协作奠定了标准化基础。

Abstract：

From March 4 to 6, 2026, the 98th annual meeting of the Japanese Gastric Cancer Association was held in Okinawa, where the updated content of the 16th edition of the Japanese classification of gastric carcinoma was released. The new edition has been revised across multiple core dimensions, including the diagnosis and treatment of esophagogastric junction cancer, specimen processing, pathological classification, invasion staging, and metastasis assessment. It adds the definition of the esophagogastric junction zone and standardizes recording methods for related cancer types, optimizes the processing procedures and evaluation criteria for endoscopic resection specimens, introduces the T_is stage and reconstructs the classification system of gastric wall invasion depth (T), improves the subclassification criteria of lymph node and distant metastasis, and supplements the relevant evaluation norms for drug and radiotherapy. This revision further unifies the standards of gastric cancer pathological diagnosis and clinical diagnosis and treatment, adapts to the development needs of genomic medicine, provides a more practical basis for the precise diagnosis and treatment of gastric cancer, and lays a standardized foundation for international exchanges and research cooperation in the field of gastric cancer.
