Efficacy and safety of Vinflunine for advanced or metastatic urothelial carcinoma in routine practice based on the French multi-centre CURVE study.
BMC Cancer 2016 March 15
BACKGROUND: To retrospectively assess the efficacy and safety of Vinflunine (VFL) under routine conditions and identify overall survival (OS) prognostic factors.
METHODS: Twenty centres participated in the retrospective study (minimum 4 patients undergoing VFL treatment for advanced/metastatic UC after platinum-based regimen progression. Primary endpoint was OS. Secondary endpoints: progression-free survival (PFS), radiological response rate (RR) RECIST criteria and toxicity (CTC NCI v3).
RESULTS: These centres enrolled 134 patients. Prior chemotherapy (CT) lines (≥ 1 palliative): 1 and ≥ 2 in 69% and 26% of patients, respectively. Performance status (PS): 0, 1, 2 in 25%, 46% and 23% of patients. Median OS = 8.2 months [6.5-9.4], PFS = 4.2 months and RR 22%, median number of 5 cycles. In risk groups based on 0-3 presence of adverse prognostic factors (PS ≥ 1, haemoglobin ≤ 10 g/dl and liver metastasis), median OS: 13.2, 9.9, 3.6, and 2.4 months (P < .0001), respectively; 3.3 months (1.9-5.6) in PS ≥ 2 subgroup.
CONCLUSION: This study reflects routine UC management and confirmed VFL patient efficacy. The drug is safe with gastro-intestinal and haematological prophylaxis. Analysis of prognostic factors for OS is consistent with pivotal trials.
