Ninety-nine patients with tongue cancer treated at Shikoku Cancer Center Hospital from 1977 to 1987 were reviewed, with special attention to prognostic factors and duration of survival.Survival rates were analized according to the Kaplan-Meier method, and the prognostic factors were correlated with distant metastases and multiple cancers.1) The 5-year survival rate was 86%, 54%, 38% and 12%, respectively for stage I, II, III and IV.2) Unfavorable factors influencing survival were multiple cancers (15 of the 99 patients, 15%) and distant metastases (12 of the 44 who died, 27%).3) A definite relationship was not found between the number of cervical lymph node and distant metastases and tumor invasion of blood vessels.4) In 40% of the patients who died, death was considered to be due to multiple cancers and distant metastases.A treatment plan of chemotherapy preceding radiotherapy in patients with advanced disease should be studied to improve the prognosis.
