Abstract
The UICC TNM classification is based on criteria for evaluating the progress of oral cancer. In the 8th edition published in 2016, the depth of invasion (DOI) in T classification and the extra nodal extension (ENE) in N classification were introduced. We evaluated for TNM classification of the cases of tongue squamous cell carcinoma who underwent surgery according to the 7th and 8th editions, and reported the practicality of the matter in the Journal of Japanese Society of Oral Oncology. In addition, UICC published an errata in 2018, and T2, T3 and T4 have been corrected. In this study, 107 cases of tongue squamous cell carcinoma that underwent surgery at our department were evaluated for the corrected TNM classification. <br>According to the errata, one case was changed from T3 to T2, and three cases were changed from T3 to T4a. Compared with the 7th edition, the rate of cases of cervical lymph node metastasis decreased in T1 and increased in T2, with similar results to the 8th edition. The survival rate decreased as the T stage increased, as in the 8th edition. In addition, since pStage was changed along with the change of pT, the survival rate decreased as the stage increased.<br>The corrected 8th edition TNM classification faithfully reflects the progress in the cervical lymph node metastasis and survival rate, and it was considered to be practical.
