Abstract
PURPOSE: To evaluate the efficacy and safety of antiangiogenic agents (sorafenib and sunitinib) as postoperative adjuvant therapy in patients with nonmetastatic renal cell carcinoma (RCC) and venous tumor thrombus (VTT). MATERIAL AND METHODS: From March 2006 to January 2016, 147 patients who met the inclusion criteria were enrolled; 27 patients received sorafenib, and 17 patients received sunitinib. After radical nephrectomy and thrombectomy, the duration of maintenance targeted medication treatment was approximately 1 year. The primary objective was to compare disease-free survival (DFS) between each experimental group and control. Secondary end points included overall survival (OS) and toxic effects. RESULTS: The three groups were well balanced in terms of age, body mass index, gender, performance status, medical history, American Society of Anesthesiologists score, surgical approach, and tumor side and size. However, more patients receiving adjuvant therapy had inferior vena cava tumor thrombus. DFS and OS did not differ significantly between groups (P = .459 and .871, respectively). After adjusting for potential confounding factors, results of multivariate analysis proved that postoperative adjuvant therapy was not an independent factor for predicting DFS and OS (P > .05 for both). The subgroup analyses for inferior vena cava tumor thrombus found similar results. The common adverse events were hand-foot syndrome, diarrhea, fatigue, and neutropenia. The adverse effects were mild in both groups, and the incidence was not significantly different between sorafenib and sunitinib. CONCLUSIONS: Adjuvant treatment postoperatively with sorafenib or sunitinib showed no survival benefit relative to control for patients with nonmetastatic RCC and VTT in a prospective cohort study.
