Background  Platinum-based systemic chemotherapy is the treatment of choice for patients with advanced urothelial carcinoma (UC). Although no chemotherapeutic regimen is established as a second-line therapy, recent studies reported that methotrexate, vinblastine, Adriamycin and cisplatin (MVAC) elicited a significant response in patients who failed gemcitabine and platinum (GP) chemotherapy. We investigated the clinical factors useful for predicting a favourable response to MVAC in UC patients who failed GP.    Methods  Forty-five patients with advanced UC who received second-line MVAC chemotherapy after failure with first-line GP chemotherapy were enrolled in this study. Univariate and multivariate analyses based on Cox’s regression were performed to identify independent prognostic factors for progression-free survival (PFS) after second-line MVAC chemotherapy.    Results  The median follow-up period after the first MVAC administration was 10.0 months. The median PFS and overall survival (OS) were 6.5 months (95 % confidence interval [CI]: 5.1–7.9) and 14.5 months (95 % CI, 7.4–21.4), respectively. The overall response rate was 57.8 %. The response to first-line GP chemotherapy (hazard ratio [HR], 2.500;  p  = 0.012) and patient age (HR, 1.047;  p  = 0.033) were predictors of PFS after MVAC chemotherapy.    Conclusions  The response to first-line GP chemotherapy and age were independent predictors of PFS in patients who received second-line MVAC chemotherapy. This report is the first to describe independent predictors of PFS after MVAC chemotherapy.
