Key result
Among 4,537 patients with primary angiosarcoma, median overall survival was 82.1 months (95% CI 76.5-87.7), with older age, male gender, advanced stage, and non-surgery associated with poor survival.
Why the study?
Limited by sample size, angiosarcoma had rarely been studied, prompting an evaluation of its characteristics and prognosis.
Population
4537 patients diagnosed with primary angiosarcoma from 1973 to 2014
Design
Population-based retrospective cohort study

In a large US population-based cohort, angiosarcoma had a median overall survival of 82.1 months, with surgery and several demographic and tumor characteristics significantly impacting prognosis.
Zhang et al. (2019) conducted an observational in Primary angiosarcoma (n=4,537). Prognostic factors (including age, gender, tumor characteristics, and surgery) was evaluated on Overall survival. Among 4,537 patients with primary angiosarcoma, median overall survival was 82.1 months (95% CI 76.5-87.7), with older age, male gender, advanced stage, and non-surgery associated with poor survival.
