BACKGROUND: Primary fibrosarcoma of the sinonasal region is an infrequently occurring malignant neoplasm. Fibrosarcomas are most commonly found in the extremities, with only 1% of fibrosarcomas reported in the head and neck region. This study analyzes the demographic, clinicopathologic, and survival characteristics of sinonasal fibrosarcoma (SNFS).
METHODS: The Surveillance, Epidemiology, and End Results (SEER) database (1973 to 2012) was queried for SNFS cases. Data were analyzed with respect to various demographic and clinicopathologic factors. Survival was analyzed using the Kaplan-Meier model.
RESULTS: Fifty-one cases of fibrosarcoma were identified in the sinonasal region. The mean age at diagnosis was 54.5 years and the mean survival was 119.7 months. There was no gender predilection with a male-to-female ratio of 1.04:1. The maxillary sinus was the most common site of involvement (54.9%), followed by the nasal cavity (23.5%). Five-year survival analysis revealed an overall survival rate of 71.7%, disease-specific survival rate of 77.8%, and relative survival (RS) rate of 78.8%. Disease-specific survival was better among those treated with surgery (with [76.2%] or without [87.5%] adjuvant radiotherapy) than those treated with primary radiotherapy alone (33.3%) (p = 0.0069).
CONCLUSION: SNFS is a rare entity. This study represents the largest series of SNFS to date. The mainstay of treatment for this tumor is surgical resection with or without radiotherapy.
