Abstract
PURPOSE: The incidence of Warthin's tumor (WT) has increased worldwide. In this study, we aimed to evaluate the incidence of WT in our hospital, which provides health care for an extremely large population. METHODS: We retrospectively evaluated 573 patients, comprising 345 males and 228 females, who all experienced parotid tumor for the past 20 years. Patients with WT that were operated in the last 20 years were evaluated according to the number of patients per year to determine the annual WT increase trend. RESULTS: In the distribution of WT over the years of surgery, the ratio of WT to all tumors irregularly changed. Furthermore, the total number of parotidectomies per year increased in time. We investigated whether WT had any increasing trend over the years. The annual percentage change (APC) of WT was calculated, and according to the segmented regression analysis, the APC was insignificant (APC = 4.3, 95% CI = - 3.6-12.9, P = 0.300). CONCLUSION: The incidence of WT has increased across the world. However, in our study, no significant APC was observed according to the segmented regression analysis.
