Abstract

Purpose: We review the indications for nephrectomy at post-chemotherapy retroperitoneal lymph node dissection, identify patients at risk for nephrectomy and assess the impact of nephrectomy on outcome. Materials and Methods: Using a computerized data base and chart review we retrospectively reviewed the records of 848 patients who underwent retroperitoneal lymph node dissection after chemotherapy. Results: En bloc nephrectomy was performed at retroperitoneal lymph node dissection after chemotherapy in 162 of the 848 patients (19%). The indications for nephrectomy included contiguous involvement of perirenal structures in 73% of the cases, renal vein thrombosis in 6%, a poorly functioning or nonfunctioning renal unit in 5% and a combination of these conditions in 16%. Pathological studies of the hilum revealed cancer in 20% of the cases, teratoma in 49% and fibrosis in 31%. Patients requiring nephrectomy had significantly more advanced disease and larger disease volume at presentation and after chemotherapy. There were no significant differences in perioperative morbidity or mortality compared with patients who did not undergo nephrectomy. Only 3 patients required perioperative dialysis and none required long-term renal support. Conclusions: These findings support en bloc nephrectomy at post-chemotherapy retroperitoneal lymph node dissection in select patients with large volume perihilar retroperitoneal disease.
