Objective:
Salivary gland tumors account for 6%-8% of head and neck neoplasms with the parotid gland as the most common primary site. Pleomorphic adenomas (PA) are considered the most common benign parotid gland neoplasms, followed by Warthin tumors (WT). The goal of this study was to investigate the distribution of parotid gland neoplasms among a United States veteran population.
Design:
Retrospective chart review.
Setting:
Washington DC Veterans Affairs Medical Center.
Participants:
Veterans who underwent fine needle aspiration (FNA) for a parotid gland mass from 2000 to 2018 were included. Medical records were reviewed for gender, age, tobacco use, surgery date, and pathology results.
Main Outcome Measures:
Changes in the distribution of parotid neoplasms and tobacco use over an 18-year period.
Results:
Of 141 patients with parotid gland masses, 86.5% (n = 122) were benign, 9.9% (n = 14) were malignant, and 3.5% (n = 5) were indeterminate. Of benign tumors, WT accounted for the majority at 51.6%, followed by PA at 40.2%. When stratified by decade (2000-2009 and 2010-2018), the proportion of WT compared to all other benign and malignant neoplasms increased from 31.6% to 53.6%, whereas the proportion of PA decreased from 36.8% to 33.3%. The rate of tobacco use was unchanged at approximately 32.0% among our cohort from 2000 to 2018.
Conclusion:
Among our cohort of veteran patients, WT was the most common benign parotid tumor and has increased in incidence over the last two decades despite an unchanged smoking rate.
