唾液腺腫瘍１５１例の臨床統計的検討

Abstract

One hundred fifty-one patients with salivary gland tumors histologically diagnosed at the Department of Oral and Maxillofacial Surgery, Kyushu University Hospital from 1982 through 2001 were clinicostatistically studied. The following results were obtained: 1. Of the total, 56.3% had benign tumors and 43.7% had malignant tumors.2. Pleomorphic adenomas were most common, comprising 47.8% of all tumors and 84.7 % of benign tumors.3. Both benign tumors and malignant tumors occurred more frequently in women.4. The average age of the patients with malignant tumors (56.6 years) was higher than that of the patients with benign tumors (49.3 years).5. With respect to the primary site, parotid gland tumors were most common, comprising 33.8% of all tumors. All sublingual gland tumors (100%) were malignant.6. The cause-specific cumulative survival rate for all patients with malignant tumors was 67.6% at 5 years and 61.7% at 10 years. Mucoepidermoid carcinoma had a good outcome, but adenoid cystic carcinoma and carcinoma in pleomorphic adenoma had poor outcomes. According to primary site, submandibular gland tumors were associated with a significantly lower cumulative survival rate than minor salivary gland or parotid gland tumors.
