Background: Previous studies have shown a modest impact of tyrosine kinase inhibitors on primary renal tumors. Those studies were mostly retrospective or heterogeneous in their eligibility criteria with regard to histology, disease stage, duration of therapy, and time off therapy prior to surgery. Objective: To prospectively investigate the safety and efficacy of axitinib in downsizing tumors in patients with nonmetastatic biopsy-proven clear cell renal cell carcinoma (ccRCC). Design, setting, and participants: This was a single-institution, single-arm phase 2 clinical trial. Patients with locally advanced nonmetastatic biopsy-proven ccRCC were eligible. Intervention: Patients received axitinib 5 mg for up to 12 wk. Axitinib was continued until 36 h prior to surgery. Patients underwent partial or radical nephrectomy after axitinib therapy… (ver más)
