The aim of this study was to evaluate the effectiveness and toxicity profile of the vinflunine chemotherapy regimen and to examine the cost-effectiveness relation in a real-world sample of patients with transitional cell carcinoma of the bladder. This is a multicenter, observational, retrospective cohort study. To assess the effectiveness and safety of vinflunine treatment, progression-free survival, overall survival, and adverse events were registered. An economic evaluation was performed and cost-effectiveness ratios were calculated. A total of 37 patients were included in the study, with a mean age of 67 (SD=9) years. The median progression-free survival was 2.61 months (95% confidence interval 1.79–4.23) and the median overall survival was 5.72 months (95% confidence interval 3.34–10.35). An objective response was achieved in eight (22%) patients. Statistically significant differences were found between patients treated with vinflunine as a second-line therapy and those treated with vinflunine as a third-line therapy (P=0.036). The most commonly reported analytical adverse event was anemia (n=34; 92%), and the most severe was neutropenia (n=19; 51%), with nine patients developing grade 4 neutropenia (9/19; 47%). The total cost of vinflunine treatment was €553 873, with a median of €8524 (interquartile range, €9220) per patient. The median-based cost-effectiveness ratio was €44 789 (€31 706–58 022) per progression-free year gained and €22 750 (€14 526–34 085) per life-year gained. The data from this study fill an important need for information on the relative value of this treatment in terms of cost-effectiveness and might help achieve an optimal quality healthcare system.
