[TNM classification system in cancer of the submandibular gland--a comprehensive retrospective study of 271 primary cases].
A total of 271 patients with submandibular gland cancer, treated in 149 hospitals in Japan in the period from 1958 to 1991, were retrospectively studied with regard to age, sex, TNM classification (UICC 1987, Geneva), histological diagnosis, therapeutic method and prognosis. The results were the following: 1. 157 males and 114 females 2. Stage I: 52 cases (19%); stage II: 64 cases (24%); stage III: 52 cases (19%) and stage IV: 103 cases (38%). 3. T1: 29 cases (11%); T2:116 cases (43%); T3: 93 cases (30%) and T4: 43 cases (16%). 4. Cervical lymph node involvement: 40%, ranging 25% in adenoid cystic carcinoma and acinic cell tumor, to 62% in undifferentiated carcinoma. 5. Distant metastasis: 11% 6.


RESULTS
adenoid cystic carcinoma 37%, adenocarcinoma 20%, mucoepidermoid tumor 16%, carcinoma in pleomorphic adenoma 10%, epidermoid carcinoma 10%, undifferentiated carcinoma 3%, acinic cell tumor 3%. 7. Treatment method: Surgical procedure alone; 51%, Combination of surgery and postoperative radiation; 18%. 8. 5-year and 10-year survival rates were 36% and 11%, respectively. 9. 5-year and 10-year survival rates varied according to the stages, being 76% and 38%, respectively, for stage I, 68% and 20%, respectively, for stage II, 15% and 10%, respectively, for stage III, and 14% and 4%, respectively for stage IV.
