Carcinoma of the salivary gland: a clinicopathologic study of 405 cases.
Four hundred five cases with carcinoma of salivary glands were analyzed clinicopathologically; 181 tumors were located in parotid, 52 were in submandibular, 21 were in sublingual, and 151 were in minor salivary glands. Mucoepidermoid carcinoma and adenoid cystic carcinoma were the most common histologic types. The overall 3-, 5-, 10-, and 15-year survival rates were 77.8%, 69.6%, 55.8%, and 36.7%, respectively. The difference between survival and recurrence-free survival rate was 9%. The prognosis of acinic cell carcinoma and mucoepidermoid carcinoma was much better than that of squamous cell carcinoma, adenocarcinoma, and undifferentiated carcinoma. The survival rates of minor salivary gland tumors was the highest, and those of submandibular gland tumors were the lowest. Postoperative radiotherapy improved the prognosis of adenoid cystic carcinoma. The overall recurrence rate was 40.2%; the cervical lymph node metastases rate was 15.3%, and the distant metastases rate was 11.1%.
