A New Model to Predict Benign Histology in Residual Retroperitoneal Masses After Chemotherapy in Nonseminoma

Abstract

The Princess Margaret model (PMM) has higher accuracy and sensitivity in the prediction of residual benign histology when compared with other models. The PMM identifies a higher number of patients for whom retroperitoneal lymph node dissection can be avoided, and gives confidence to be used as an extensive and prospective clinical application.
