The 5th edition of TNM Classification was published by the UICC (International Union Against Cancer) in 1997. In the classification of gastric cancer, anatomical subsites and N category were newly published. The new classification and role of the Japanese TNM Joint Committee were described in this paper. The Japanese committee had strongly advocated to continue "the anatomical N classification", because the hazard ratios were more significant for prognosis of patients with gastric cancer, and had many reasonable and scientific advantages. However, the UICC introduced "a new N classification by number of metastatic lymph nodes" because of the difficulty in studying nodes by anatomical classification. The new TNM can not be considered an improved classification, and so we are looking for a more scientific, practical, and internationally acceptable classification.
国际抗癌联盟（UICC）于1997年发布了第5版TNM分类法。在胃癌分类中，新公布了解剖亚部位和N分类。本文阐述了日本TNM联合委员会的新分类及其作用。日本委员会强烈主张继续采用“解剖学N分类”，因为其对胃癌患者预后的风险比更显著，且具有诸多合理科学的优势。然而，由于按解剖学分类研究淋巴结存在困难，UICC引入了“按转移淋巴结数量的新N分类”。新的TNM分类法不能被视为一种改进后的分类，因此我们正在寻找一种更科学、实用且国际上可接受的分类方法。
