Head and neck sarcomas: treatment outcomes in a tertiary referral center in Argentina.

Purpose: To analyze the clinical findings, management, and results of oncological treatments and to identify prognostic factors in patients diagnosed with head and neck sarcoma. Methods: We performed a retrospective analysis including 48 adult patients with primary head and neck sarcomas, treated between 2006 and 2018 in a referral center of Argentina. Results: The median follow-up time was 44 months (range: 4–146 months). Five-year overall survival was 68%. On univariate analysis, radiation-induced sarcomas (p=0.038) had worse survival. Five-year disease-free survival was 58% and local recurrence at 2 years was 22.7%. On multivariate analysis, positive/close resection margins (p=0.031), radiation-induced sarcomas (p=0.037), and mandibular and oral cavity location (p=0.002) were independent prognostic factors associated to local recurrence and shorter disease-free survival. Conclusion: Head and neck sarcomas are a rare entity. Surgery is feasible in more than 80% of patients, with an acceptable overall and disease-free survival. Radiation-induced sarcomas, location in the mandible and oral cavity, and close margins were significant prognostic factors in our population. [ABSTRACT FROM AUTHOR]
