FIG 2.

Presentation characteristics and DSD in patients with myxofibrosarcoma. (A) Clinicopathologic factors in all patients presenting with RAS MFS compared with all patients presenting with sporadic MFS. (B) Cumulative incidence of DSD in all patients with RAS MFS (blue) compared with all patients with sporadic MFS (red). (C) Cumulative incidence of DSD in propensity-matched patients with RAS (blue) and sporadic (red) MFS. ^aPostmatch P value is derived from Cox regression model with sandwich estimator to control for correlation between matched samples rather than directly from the displayed cumulative incidence curve. DSD, disease-specific death; MFS, myxofibrosarcoma; RAS, radiation-associated sarcoma.
