BACKGROUND: Most available epidemiological studies on parotid neoplasms consists simply of single institution reports without a detailed statistical assessment, probably due to the rarity of these lesions and their histological heterogeneity. Aim of this report is to provide a multicenter epidemiological collection of parotid neoplasms in central Italy.
METHODS: A retrospective data collection was performed by four major health institutions in central Italy: San Camillo Forlanini Hospital (Rome), San Filippo Neri Hospital (Rome), San Camillo De Lellis Hospital (Rieti) and Fabrizio Spaziani Hospital (Frosinone). The accrual period ranged from 2009 to 2020 and we included data about gender, age, incidence for decades, side, size, histology, and type of surgical procedures used according to the European Salivary Gland Society (ESGS).
RESULTS: The overall number of patients was 525 with a mean age of 59.2 years. Neoplasms were benign in 86% and only 14% were malignant. Among benign forms, the prevalent entities were Warthin tumor and pleomorphic adenoma. Among malignant lesions, the most common histotypes were lymphomas, squamous cell carcinoma and mucoepidermoid carcinoma. Major benign neoplasms were mainly treated with parotidectomy I-II while for the malignant forms the most used surgical procedure was parotidectomy I-IV.
CONCLUSIONS: A better knowledge of the epidemiological data should be achieved to help clinicians ensure the best health assessment for patients affected by parotid neoplasms.
