Presentation characteristics and DSD in patients with AS. (A) Clinicopathologic factors in all patients presenting with RAS AS compared with all patients presenting with sporadic AS. (B) Cumulative incidence of DSD in all patients with RAS AS (blue) compared with all patients with sporadic AS (red). Because of the differences in presentation between RAS AS and sporadic AS, a well-matched cohort could not be defined. AS, angiosarcoma; DSD, disease-specific death; RAS, radiation-associated sarcoma.
