During the 10 years from January 1, 1971 to December 31, 1980, 113 patients with histologically proven carcinoma of the lip and oral cavity were treated at the Department of Otolaryngology, Kurume University Hospital. Among the entire 113 cases, the site of the primary lesion was the lip in 3, the buccal mucosa in 7, the upper alveolus and gingiva in 6, the lower alveolus and gingiva in 6, the hard palate in 9, the tongue in 65, the floor of the mouth in 17 cases. The results of treatments were discussed chiefly for those patients who had not been previously treated and underwent curative treatment. They can be summarized as follows : (1) In 54 patients of carcinoma of the tongue who underwent curative treatments, the 3- and 5-year cumurative survival rates were 72.5% and 61.4%, respectively. Of the 19 patients who died, the cause of death was primary lesion in 3 (16%), neck metastasis in 6 (32%), distant metastasis in 1 (5%), complication in 2 cases (11%). (2) In 16 patients of carcinoma of the floor of the mouth who underwent curative treatments, both 3- and 5-year cumurative survival rates were 50% . The more advanced the disease was, the lower the survival rate. Of the 8 patients who died, the cause of death was primary lesion in 4, neck metastasis in 1, distant metastasis in 1, and surgical and other complications in 2. (3) In 21 patients of carcinoma of the other sites who underwent curative treatments, the 3- and 5-year cumurative survival rates were 60 % and 40% for the buccal mucosa, 66.7% and 66.7% for the upper alveolus and gingiva, 58.4% and 58.4% for the lower alveolus and gingiva, 25% and 25% for the hard palate, respectively.
