The TNM classifications of neuroblastoma, nephroblastoma and soft tissue sarcoma were adopted at the International Conference for TNM Classification (UICC) held in May 1980. There is no TNM system under contemplation, however, for primary liver carcinoma in childhood. Accordingly, we have formulated the proposed Japanese TNM system for this carcinoma in children and examined its validity in 136 cases of hepatoblastoma seen in the listed 14 institutions. The basic policy of the Committee on the Japanese TNM Classification is not to include the resectability of the tumor and regional lymph nodes or any other status of the disease resulting from therapeutic intervention as a component of the pTNM system. This is a feature which makes our proposed system widely divergent from the accepted classification scheme for the three types of tumor cited above.
1980年5月举行的国际TNM分类会议（国际抗癌联盟）采用了神经母细胞瘤、肾母细胞瘤和软组织肉瘤的TNM分类。然而，目前尚无针对儿童原发性肝癌的TNM系统。因此，我们制定了日本儿童肝癌TNM系统建议方案，并在列出的14家机构中观察到的136例肝母细胞瘤病例中检验了其有效性。日本TNM分类委员会的基本政策是，不将肿瘤及区域淋巴结的可切除性或因治疗干预导致的疾病其他状况纳入pTNM系统。这一特点使得我们提出的系统与上述三种肿瘤公认的分类方案有很大差异。
