    Abstract:
    OBJECTIVE: A prospective phase II study was conducted to evaluate the efficacy and toxicity of oxaliplatin plus 5-fluoruracil (5-FU) and high-dose leucovorin (LV) (FOLFOX-4) in patients with platinum-resistant, taxane-pretreated recurrent ovarian cancer. PATIENTS AND METHODS: Thirty-eight patients, with a median age of 58 years (range 33-77), were treated with oxaliplatin 85 mg m(-2) as a 2-h infusion on day 1, LV 200 mg m(-2) day(-1) as a 2-h infusion followed by bolus 5-FU 400 mg m(-2) day(-1) and a 22-h infusion of 5-FU 600 mg m(-2) day(-1) for 2 consecutive days. Treatment was repeated every 3 weeks. Patients were evaluated for response every two cycles. RESULTS: The vast majority of patients had performance status 0 or 1 and 76.3% had > or = 2 metastatic sites. A median number of four cycles per patient (range, 1-8) were administered. Based on an intention-to-treat analysis, 3 patients (7.9%) achieved a complete response (CR) and 8 (21.1%) achieved a partial response (PR), for an overall response rate of 29%. Another 29% of patients had stable disease (SD). The median relapse-free survival was 5.2 months (range 2.5-17), the median time to tumor progression was 4.8 months (range 0.6-19), and the median overall survival was 10.1 months (range 0.2-36). Toxicity was mild to moderate. Grade 3/4 neutropenia and thrombocytopenia occurred in 29% and 21.1% of patients, respectively. Febrile neutropenia was encountered in 3 patients (7.9%), who were successfully treated. Grade 3/4 neurotoxicity developed in 15.8% of patients; neurotoxicity gradually declined after treatment discontinuation. Alopecia, nausea-vomiting, diarrhea, mucositis, and asthenia were not a serious problem. There were no treatment-related deaths. CONCLUSION: The combination of oxaliplatin and 5-FU/LV (FOLFOX-4) appears to be an effective regimen with a good toxicity profile for the treatment of platinum-resistant, taxane-pretreated ovarian cancer.
