Demographics of Salivary Gland Tumors: An Institutional Study in Western Uttar Pradesh

Abstract

　AIM OF STUDY: Salivary gland tumors are uncommon, and the epidemiological data of these tumors in various parts of the world can be helpful for a better understanding of their biology and clinical characteristics. Thus, this study was an epidemiological survey of salivary gland tumors in the western Uttar Pradesh population.
　MATERIALS AND METHODS: This retrospective study was a clinical review ofour experience with different subtypes of salivary gland tumors, diagnosed from May 2004 to May 2010. The histological diagnoses were evaluated according to the 2005 WHO classification. These data were analyzed for the distribution of benign and malignant salivary tumors in minor salivary glands, male to female ratio, age range, and site of occurrence.
　RESULTS: A total of1805 specimens were received; ofthese, 4% were diagnosed as salivary gland tumors, with a male to female ratio of1:1.4. The mean age ofthe patients was 51.4±18.1 years. Ofthe tumors, 59.5% were benign and 40.5% were malignant neoplasms, with the most common tumors being pleomorphic adenoma and mucoepidermoid carcinoma.
　CONCLUSION: The present study provides demographic data on a series ofsalivary gland tumors in the western Uttar Pradesh population. This study confirmed that some tumors have a predilection for certain sites, and that the risk of malignant disease is also greater at specific sites within the oral cavity.
