Angiosarcomas (AS) are an aggressive subtype of head and neck tumors. Current outcome research is limited to single-surgeon and/or single-institution data. This study analyzes the Surveillance, Epidemiology, and End Results program (SEER) database data to improve outcomes of head and neck AS. In this study, the authors accessed the SEER database from 2000 to 2020 to identify patients who underwent surgical and/or nonsurgical treatment of head and neck AS. Data included demographics, diagnostic workup, tumor characteristics, treatment pathways, and therapy outcomes. The study included 691 patients (210 females, 481 males) with AS of the head and neck. The median tumor size was 40 mm. Most patients (63%) underwent surgery, with surgery followed by radiation being the most common treatment combination (50%). Median survival was 16 months. Patients treated with surgery showed significantly longer survival (18 mo) compared with nonsurgery cases (12 mo, P<0.001). Neoadjuvant treatment significantly improved survival (28 mo) compared with non-neoadjuvant cases (15 mo, P=0.023). Adjuvant treatment also improved overall survival (19 mo) versus nonadjuvant treatment (14 mo, P<0.001). There was no significant difference between neoadjuvant and adjuvant treatment outcomes (P=0.270). Bottom of Form This study compares the outcomes of multimodal treatments, especially surgery and radiotherapy, for head and neck AS, emphasizing tailored approaches to optimize patient outcomes and extend survival. Future research should refine these strategies.
