Abstract
OBJECTIVES: The purpose of this work was to investigate the effect of sorafenib or sunitinib as neoadjuvant therapy on the survival outcomes of renal cell carcinoma (RCC) with tumor thrombus. METHODS: A total of 92 RCC patients with tumor thrombus were included in this 2-center retrospective research from January 2007 to December 2014. Sorafenib and sunitinib were administered as neoadjuvant therapy in 9 patients and 14 patients, respectively, and 69 patients constituted non-neoadjuvant therapy groups. The Kaplan-Meier method was used to estimate the recurrence-free survival (RFS) and overall survival (OS). Log-rank test was used to compare the survival outcomes of patients with or without neoadjuvant therapy. RESULTS: The overall median RFS and OS time for all 92 patients were 28 months (95% CI 17-39 months) and 42 months (95% CI 30-54 months). Patients with neoadjuvant therapy had no significantly longer median RFS (30 vs. 28 months, p = 0.376) and OS (45 vs. 42 months, p = 0.702) than those without neoadjuvant therapy. CONCLUSIONS: Neoadjuvant therapy of sorafenib or sunitinib might not improve survival outcomes for high risk RCC patients with tumor thrombus. Thus, neoadjuvant therapy for RCC with tumor thrombus should be considered cautiously.
