Research progress of prognostic factors and prediction tools for retroperitoneal soft tissue sarcomas

Retroperitoneal sarcomas (RPS) are rare malignant tumors, and their pathological types are complex and varied. With the insight of RPS, the histological types, TNM stage, surgical extension, and adjuvant therapy all affect the prognosis of RPS patients to different degrees.The current nomograms can partially predict the overall survival (OS) and disease-free survival (DFS) of RPS patients, but due to their limited value, they cannot guide the post-operative treatment of RPS patients. This review mainly focuses on the prognostic factors and prediction tools for RPS.
