わが教室16年間の舌悪性腫瘍の統計的観察

CANCER OF THE TONGUE, A STATISTICAL ANALYSIS OF EIGHTY FOUR CASES

　I．はじめに

　昭和31年4月より昭和47年3月までの16年間に，われわれの教室で治療した舌悪性腫瘍の統計的観察を試みた。その目的は，第1にわれわれの教室の今回の最近16年間の集計と過去の昭和7年から16年までの10年間の集計^1）との比較，および諸家の報告との比較検討，反省を試みること，第2にその治療成績の検討から明日への治療指針を導くことである。

　Eighty four cases of lingual cancer treated at the department of otolaryngology of Kyoto prefectural medical university, during the period of 16 years, 1956-1972, are reported.

　These cases consisted of 10 of root involvement (12%) and 74 of that of the body (88%). Forty seven cases out of the total number (56%) showed cervical metastasis at the time of admission.

　The prognosis of the root involvement was worse than that of the body. Five year survival rate for the former was 0%, while the latter was 45%. The overall 5 year survival rate for the 84 cases was 43%.

　Sixty six cases were treated surgically which included those treated before and after-irradiation, while, 18 cases were treated by irradiation with added chemotherapy. The results of these treatments indicated that the first choice should be glossectomy with extensive neck dissection.

　However, it has been recently reported that the prognosis of an early carcinoma of the tongue treated, either, by irradiation therapy or that of surgery is equally as good. From these facts, it may be summarized that the irradiation therapy which is more in line with preservation of the function of the organ should be used more often in the future.
