Background: Parotid cancers are uncommon and have a relatively long natural history. Determination of prognostic factors affecting the outcome is difficult. Materials and Methods: The primary objective was to determine the demographic, clinical, histopathology and treatment-related factors affecting overall survival (OS)in parotid cancers. The secondary objective was to study the impact of these factors on disease-free survival (DFS) and patterns of failure. Data of consecutive patients who underwent parotidectomy for primary parotid malignancy between July 2006 and April 2015 with at least 6 months of posttreatment follow-up were retrospectively retrieved.
Patients whose follow-up status was known at the time of analysis were included. One hundred and sixty-five patients met the inclusion criteria. Results: The median follow-up was 38 months. The mean OS and DFS were141.03 and 124.38…
