Abstract: Introduction: Mucoepidermoid carcinoma (MEC) is the most common malignant salivary gland tumor, however few studies have been reported in Brazilian populations. Aim: To report clinical and pathologic data from 173 head and neck MEC treated in the Treatment and Research Center at Hospital do Câncer A. C. Camargo in São Paulo. Study design: Clinical randomized. Material and Method: From 1953 to 1997, 173 cases of MEC were found in the medical files of the center. Data were obtained from the patients' records and histological review of all cases. Results: The mean age of the patients was 44 years and 93 (53.8%) were men; parotid glands were affected in 61 cases (35.2%) and intraoral minor salivary glands in 75 (43.4%). TNM revealed 50.3% of the cases in stages I and II, and histological grading revealed 45.2%, 18.5% and 36.3% low-grade, intermediate-grade and high-grade tumors, respectively. Surgical treatment was employed in 80.3% of the cases, with neck dissection in 52 cases (30.1%), and radiotherapy in 73 (42.2%). Local recurrence, regional and distant metastases were found in 12.7%, 9.8% and 9.2% of the patients, respectively; 5-year and 10-year overall survival rates were 70% and 60%, respectively. Conclusions: MEC affected mainly the parotid gland and the palate of adults, without gender preference. Half of the cases were diagnosed at initial clinical stages and 64% of the tumors were low or intermediate-grade lesions. Surgery was the treatment of choice and prognosis was good.
