Abstract

The success of immune checkpoint inhibitors in metastatic renal cell carcinoma (RCC) has renewed interest in studying these agents in preoperative settings. Here, we present a case of metastatic RCC with an inferior vena cava (IVC) tumor thrombus extending to the right atrium. Preoperative systemic therapy with ipilimumab/nivolumab was initiated for four cycles. The IVC tumor thrombus level was significantly downstaged from IV to I according to the Mayo classification, which enabled us to perform cytoreductive nephrectomy and IVC thrombectomy without extracorporeal circulation. Preoperative ipilimumab/nivolumab may lead to significant downstaging of caval tumor thrombus in metastatic RCC.
