Prognostic models for RPS patients-Attempting to predict patient outcomes.

Retroperitoneal sarcoma (RPS) patients can have variable of outcomes after surgery. The chance to recur locally or at distant sites varies according to tumor grade, histologic subtype, and other patient- and tumor-related characteristics. The relative contribution of each prognostic variable on the oncological outcome of RPS patients can be weighted by combining them in prognostic tools such as nomograms. With this review, we critically appraise the available nomograms for RPS patients highlighting pros and cons.
