Abstract:
Objective To investigate the efficacy and safety of sunitinib as first-line therapy for metastatic renal cell carcinoma ( mRCC) on a 2 weeks on/1 week off intermittent dosing schedule.Methods A total of 11 mRCC patients were enrolled to receive sunitinib 50 mg/day in 2 weeks on/1 week off schedule per 6 weeks till disease progression or intolerable toxicity occurred.The primary end point was progression free survival ( PFS) , the secondary end points were overall survival ( OS) , incidence of adverse effects and objective response.Results The objective response rate in the 11 cases was 45.5%and disease control rate 72.7%( partial response n=5, stable disease n=3) .Till the last follow up on Dec 2013, the median PFS was 17.0 months (95%CI 7.3 to 26.7 months), and median OS 26.0 months (95%CI 2.2 to 49.8 months). The common adverse events included leucopenia, thrombocytopenia, diarrhea, mucositis and hand-foot skin reaction.Dose reduction to 37.5 mg was seen only in 2 patients without discontinuation. Conclusions Sunitinib on an intermittent dosing schedule 2 weeks on /1 week off as first-line therapy for mRCC patients shows a good efficacy and tolerance, with less grade 3-4 drug-related toxicities and a tendency of prolonged PFS in mRCC patients.
