Abstract

Abstract: Background: Given the rarity of dermatofibrosarcoma protuberans (DFSP) of the head and neck, the incidence and prognosis specific to this region are poorly defined. The purpose of this study was to determine epidemiology, clinicopathological characteristics, and prognostic factors of patients with DFSP of the head and neck region, using the Surveillance, Epidemiology, and End Results (SEER) database. Methods: A cohort analysis was performed for primary head and neck DFSP reported to the SEER database between 2000 and 2018. Overall survival was determined using Kaplan–Meier analysis while Cox regression modeling was used to examine predictive factors. Results: A total of 681 cases were reported to the SEER database between 2000 and 2018. Incidence rates decreased over time. Overall survival was 94%, and disease‐specific survival was 99% at 5 years. Cases of head and neck DFSP were found to occur more frequently in males. There was no difference in incidence rates between White patients and Black patients. Age ≥ 60 years old, tumor size, and living location were the most significant predictors of overall survival. Conclusions: This analysis of DFSP of the head and neck demonstrates a downward trend in incidence, higher age‐standardized incidence in males, and similar race‐based incidences, which differs from data reported on DFSP of other anatomic locations.
