Outcomes in Patients With Clinical Stage III NSGCT Who Achieve Complete Clinical Response to Chemotherapy at Extraretroperitoneal Disease Site

A CCR at the ERP disease site is associated with a greater likelihood of relapse compared with a PCR, underscoring the limitations of radiographic imaging after chemotherapy in detecting microscopic residual disease and need for rigorous monitoring of patients observed after a CCR. Furthermore, until more accurate clinical predictors of ERP histologic features are identified, we advocate for complete surgical resection of all sites of residual disease, when feasible.
