Abstract
Salivary gland tumors represents approxima tely 3% of all head and neck neoplasms. Most of them are benign and located in the parotid gland. Aim: Epidemologic analysis of salivary gland neoplasms in the Wrocław ENT Department. Material and methods: 304 patients (170 women, 134 men) with histologically confirmed salivary gland tumors treated in the years 2001–2010 were reviewed retrospectively. Results: Benign tumors were diagnosed in 83.9% of patients, malignant lesions constituted 16.1% of cases. The average age of patients were 55 years. Pleomorphic adenoma and Warthin's tumor constituted the most common benign tumor (93.3%). Among malignant tumors – adenoid cystic carcinoma (24.5%) and adenocarcinoma (22.5%) were the most frequent. Neoplasms located in submandibular gland and in minor salivary gland in the vast majority of cases were malignat: 35.1% and 38.9%, respectively. Parotid gland tumors were malignant in 11.7%. An increase of salivary gland neoplasms total number, predominantly in men, and in malignant neoplasms percentage: from 13.8% in the years 2001–2005 to 17.7% in the years 2006–2010, was noted. Conclusions: Most of salivary gland neoplasms are benign. Pleomorphic adenoma and Warthin's tumor (93.3%) constituted the most common benign tumors, adenoid cystic carcinoma (24.5%) and adenocarcinoma (22.5%) were the most frequent malignant tumors. Malignant tumor patients were avereage 12.5 years older than benign tumors persons. More than 1/3 of submandibular gland and minor salivary glands neoplasms were malignant. An increase of malignant lesions was noted – from 13.8% to 17.7% of the total number of salivary gland neoplasms.
