Figure 3A. Multivariate Recursive Partitioning Analysis for Overall Survival. The primary factor associated with survival was clinical stage (localized versus metastatic). Among patients with localized disease, tumor size was the strongest factor associated with survival. Among patients with metastatic disease, the percentage sarcomatoid was the strongest factor associated with survival. In this setting, having a sarcomatoid percentage more than 40% is associated with the worst survival. PSC= Percent sarcomatoid component
