64 cases of primary tongue cancer were studied from 1973 to 1985 in the Department of Oral and Maxillofacial Surgery at Kyoto University Hospital and the following results were obtained.
1) The 64 patients consisted of 35 males and 29 females with an age average of 53.8.
Pain was the most frequent chief complaint, and 48. 4 % of them visited our clinic within 3 months after onset of the symptom.
2) 63 of 64 cases were pathologically diagnosed as squamous cell carcinoma. In stage classification, Stage I: 2 cases, Stage 11: 20 cases, Stage III: 27 cases, Stage IV: 15 cases.
3) 73% of 64 cases were treated by surgery and radiotherapy. Pull through operation was the most frequent in surgery and external radiotherapy was given in almost all the cases post operatively. Prophylactic upper neck dissection was done in 73.7% of 38 cases.
4) The accumulated 5-year survival rate was 65.6% in all cases, and 73.9 % in 47 cases of surgery + radiotherapy group. On the other hand, it was 55.6% in 6 cases of surgery group, and 35.1% in 10 cases of radiotherapy group.
5) The higher the stage and the lower the histological differentiation, the lower the accumulated 5-year survival rate tended to be.
