FIG 4.

Presentation characteristics and DSD in patients with undifferentiated pleomorphic sarcoma. (A) Clinicopathologic factors in all patients presenting with RAS UPS compared with all patients presenting with sporadic UPS. (B) Cumulative incidence of DSD in all patients with RAS UPS (blue) compared with all patients with sporadic UPS (red). (C) Cumulative incidence of DSD in propensity-matched patients with RAS (blue) and sporadic (red) UPS. ^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; RAS, radiation-associated sarcoma; UPS, undifferentiated pleomorphic sarcoma.
