Epidemiological and clinical characteristics of 705 salivary glands neoplasms
Journal Title: Otolaryngologia Polska - Year 2013, Vol 67, Issue 3
Abstract
The epidemiological data concerning the rare group of tumors derived from salivary glands recorded in the National Cancer Registry is insufficient because it records only malignant salivary glands tumors. Aims of the study: The epidemiological and clinical characteristics of 699 patients with salivary glands tumors (n = 705). Material: The data were retrieved from ENT Department District Hospital in Kielce (01.09.1989–28.02.2001) and from Department of Otolaryngology Head and Neck Surgery Holy Cross Cancer Centre in Kielce (01.03.2001–31.12.2008). Results and conclusions: In the analyzed group of 699 patients with 705 salivary glands tumors women predominated, consisting 54,2% of all group. The average age in group of malignant tumors was higher than in nonmalignant group. The risk of malignant neoplasms development increased with patient age. In the analyzed group of 705 salivary glands tumors the nonmalignant neoplasms dominated–78,3%. Out of all cases, 547 (77,6%) were localized in the parotid gland, 80 (11,3%) in submandibular gland and 78 (11,1%) in minor salivary glands. Nonmalignant tumors were more frequent in the parotid gland (82,8%) and submandibular gland (71,3%), whereas in minor salivary glands nonmalignant and malignant neoplasms the occurrence was nearly the same. In general–the smaller the salivary gland, the risk of development malignant tumors was higher. In group of nonmalignant salivary gland tumors two histopathological types dominated – pleomorphic adenoma and Warthin's tumor, which comprised 91,8% of the whole group. In the group of 153 malignant salivary gland tumors the most common histopathology were – adenoid cystic carcinoma, mucoepidermoid carcinoma and adenocarcinoma. In the analyzed period of 20 years' time, the incidence of salivary glands tumors increased with high siginificance, both for nonmalignant, as well malignant tumors.
