Role of postchemotherapy retroperitoneal lymph node dissection in advanced germ cell tumors.

Advanced germ cell tumors (GCTs) are curable with the appropriate integration of cisplatin-based chemotherapy and postchemotherapy surgical resection of residual masses. For men with retroperitoneal metastases, postchemotherapy retroperitoneal lymph node dissection (PC-RPLND) is a vital component of this treatment algorithm. The rationale for PC-RPLND is based on the consistent 10% to 20% and 35% to 55% incidence of viable malignancy and teratoma, respectively. Prognostic factors and nomograms cannot predict the presence of necrosis with sufficient accuracy to obviate the need for PC-RPLND. This article reviews the indications, technique, and outcomes of PC-RPLND in the management of advanced GCT.
