Abstrakt: Simple Summary: Angiosarcoma is a rare type of soft tissue sarcoma with a progressive and unpredictable disease course. Currently, surgery is the only well-defined treatment option. Adjuvant oncological treatment remains inconclusive. In effort to provide evidence for improved management and follow-up, the purpose of this study was to assess treatment outcomes and identify prognostic factors. We identified a nation-wide cohort of 154 patients with complete follow-up. Adjuvant oncological treatment did not benefit overall survival, risk of metastasis, or recurrence. Cutaneous tumors, surgery, and negative margin showed improved overall survival, yet without reducing the risk of recurrence and metastasis, resulting in a grave overall survival rate. Angiosarcoma is a rare aggressive and understudied soft tissue sarcoma with pending evidence-based treatment guidelines due to varying study cohorts and inconsistent outcome measures. Surgery with wide resection is currently considered to be the cornerstone in management. In a population-based cohort identified from Danish National Health Registers between 2000 and 2017, this study aimed to define prognostic factors in patients with newly diagnosed soft tissue angiosarcoma. Kaplan–Meier survival analysis demonstrated 5-year overall survival of 28%. Competing risk analysis demonstrated cumulative incidence of local recurrence of 30% and metastasis of 43%. Multivariable Cox models among 154 included patients demonstrated age above 60 years and metastasis to be independently associated with worse overall survival. Cutaneous tumors, surgery, and negative resection margin were independently associated with improved overall survival. Adjuvant oncological treatment did not improve overall survival, risk of metastasis, or recurrence. Negative margin was not associated with lower risk of recurrence and metastasis. We conclude that, despite demonstrated improved survival after surgery with wide resection, overall survival remains poor. [ABSTRACT FROM AUTHOR]
