title: Evaluation of the influence of systemic neoadjuvant chemotherapy on the survival of patients treated for invasive bladder cancer.
abstract: OBJECTIVE
  To assess the influence of neoadjuvant systemic chemotherapy using a modified methotrexate, vinblastine, doxorubicin and cisplatin (MVAC) scheme in patients with invasive bladder cancer.
  
  
  METHODS
  Two groups of patients were reviewed retrospectively; group 1 included 51 who received chemotherapy before cystectomy and group 2 included 62 who were treated only with surgery. The mean (range) duration of follow-up was 3.2 (0.25-10.25) years. The patients in group 1 were divided into two subgroups: those with tumour confined to the bladder (T1, T2 and T3a) and the remaining patients with tumour beyond the bladder (T3b, T4a,b). The chemotherapy was administered as routine MVAC, except vinblastine and methotrexate were given at 15 and 22 days during the cycle. A mean of three cycles were administered.
  
  
  RESULTS
  The 5-year survival rate in group 1 and 2 was 66% and 58%, respectively (P > 0.3); after 8 years of follow-up the survival rates were 58% and 33%, respectively, and significantly different (P < 0.01).
  
  
  CONCLUSIONS
  Systemic chemotherapy using the modified MVAC scheme in patients subsequently undergoing radical cystectomy improved the survival rate after 8 years of follow-up.
