Clinical Analysis of Parotid Tumors in Patients Over 60-year-old: A Retrospective Study of 78 Cases

Abstract

Background: The aim of this study was to review the epidemiologic characteristics, management and treatment outcome of elderly parotid tumors. Methods: From January 2010 to December 2013, Seventy-eight patients ≥60-year-old with a diagnosis of parotid tumor were identified based on their medical records. Results: The 78 patients comprised 38 males and 40 females. Sixty-seven (85.9%) patients had a benign tumor and 11 (14.1%) patients had a malignant tumor. The most common benign tumor was Warthin tumor (n = 26) and the most common malignant tumor was salivary duct carcinoma (n = 5). Fine needle aspiration cytology had a diagnostic sensitivity of 100%, positive-predictive value of 97.0%, and accuracy of 97.3% for diagnosing benign parotid tumors. Conclusions: Warthin tumor was the most common benign tumor, and salivary duct carcinoma was the most frequent malignant tumor in this study. Surgical treatment is the mainstay treatment for benign and malignant parotid tumors.
