FIG 1.

Presentation characteristics and DSD in patients with malignant peripheral nerve sheath tumors. (A) Clinicopathologic factors in all patients presenting with RAS MPNST compared with all patients presenting with sporadic (non–NF1-associated) MPNST. (B) Cumulative incidence of DSD in all patients with RAS MPNST (blue) compared with all patients with sporadic MPNST (red). (C) Cumulative incidence of DSD in propensity-matched patients with RAS (blue) and sporadic (red) MPNST. ^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; MPNST, malignant peripheral nerve sheath tumor; RAS, radiation-associated sarcoma.
