Resumen:
Purpose The aim of this multicenter study was to evaluate the clinical outcomes of patients with metastatic renal cell carcinoma (mRCC) who received sunitinib retreatment. Methods Clinical data from patients treated with sunitinib rechallenge in nine Spanish centers were retrospectively analyzed. All patients received first-line sunitinib until progression or intolerance, followed by one or more successive drugs and rechallenge with sunitinib thereafter. Results Thirty-seven patients were included. At first-line treatment, objective response rate (ORR) was 69.4% and median progression-free survival (PFS) was 19.4 months. At rechallenge, ORR was 27.2% and 39.4% of patients obtained stabilization of disease. Median PFS was 6.2 months. Clinical benefit was obtained by 21 patients (75%) with > 6-month interval between sunitinib treatments and by 1 patient (20%) among those with <= 6-month interval (P = 0.016). Hemoglobin levels >= lower level of normal were associated with clinical benefit (P = 0.019) and with PFS (P = 0.004). Median overall survival from start of first-line sunitinib was 52.7 months. No new adverse events were observed at rechallenge. Conclusions Sunitinib rechallenge is a feasible treatment option for selected patients with mRCC.
