Surgical Management with Extraction Technique of Renal Cell Carcinoma with Inferior Vena Cava Tumor Thrombus.

Abstract

In renal cell carcinoma with the tumor thrombus extension in inferior vena cava (IVC), radical nephrectomy with thrombectomy has been reported to improve the prognosis. However, perioperative morbidity and mortality rates of the radical surgery are still high. Therefore a less invasive and more sophisticated way of surgery is necessary to improve the outcome. In this study, we retrospectively reviewed our experience of patients with tumor thrombus extension in IVC and assessed the results of the tumor thrombus extraction technique and the effect of preoperative neoadjuvant targeted molecular therapy on the thrombus size and surgical management.
