【 摘 要 】

Background: Salivary gland tumors are uncommon. This study aimed toinvestigate both clinical and epidemiological aspects of minor salivary glandtumors in a Brazilian population. Methods: From 1976 to 2007, data obtainedfrom clinical records and histological diagnoses were reviewed according tothe WHO. Results: A total of 217 MSGTs were identified. Pleomorphic adenomas(83%) and adenoid cystic carcinomas (28.8%) were the most frequent ones. Themean age of patients with benign and malignant tumors was 54.7 and 44.7years, respectively. There was a female predominance and the palate was themost affected location. Surgery was the treatment of choice, but adjuvantradiotherapy and/or chemotherapy were also used. Recurrence rate of benignand malignant tumors was respectively 11.2% and 20.4%. Conclusion: thispopulation showed a relatively higher proportion of malignant tumors, andthese tumors were associated with a higher rate of recurrence when comparedto benign tumors. However, the overall recurrence of 16.2% was also withinthe reported range for these tumors. In addition, despite the results of thisstudy are similar to previous series found in the literature, it provides animportant insight into the epidemiology of patients presenting minor salivarygland tumors.
