Abstract

From March 4 to 6，2026，the 98th Annual Meeting of the Japanese Gastric Cancer Association (JGCA) was held in Okinawa, Japan, where the 16th edition of the Japanese Classification of Gastric Carcinoma (hereinafter referred to as the Classification) was also released. This edition has undergone significant modifications, maintaining consistency and continuity with the 15th edition of the “Classification of Gastric Carcinoma” and the 12th edition of the “Classification of Esophageal cancer”, aligning with the TNM classification of the UICC/AJCC, and incorporating new provisions. The 16th edition of the “Classification of Gastric Carcinoma” primarily revises the methods for recording the cancer at the gastroesophageal junction, the staging of gastric cancer progression, the state of the cancer, and the evaluation methods for treatment outcomes.

Key words

gastric carcinoma / esophagogastric junction carcinoma / progressive staging / classification of gastric carcinoma / classification of esophageal cancer
