title: [Prognosis in pT3b infiltrating tumors of the bladder treated by adjuvant chemotherapy].
abstract: OBJECTIVE
  To evaluate the prognosis of stage pT3bM0 invasive urothelial bladder tumours treated by cystectomy alone or combined with adjuvant chemotherapy according to the MVAC protocol (methotrexate, vinblastine, adriamycin and cisplatin).
  
  
  METHODS
  From 1987 to 1996, 90 patients with stage pT3M0 urothelial bladder tumours were treated with isolated cystectomy (n = 69) or followed by MVAC chemotherapy (n = 21). Lymph node stage was N0 (n = 55), N+ (n = 29) or Nx (n = 6). Essentially selected because of their good general status, patients treated with chemotherapy had a lymph node stage N0 (n = 7) or N+ (n = 14). Chemotherapy had to be suspended in 2 cases and with a fatal outcome during treatment in 4 cases, due to tumour progression, surgical complication or bone marrow aplasia.
  
  
  RESULTS
  65 deaths have occurred with a follow-up of 2 to 120 months (m = 15), including 2 postoperative deaths, 39 cancer deaths and 14 intercurrent deaths. The 1-year, 2-year and 5-year actuarial survival rates were 70%, 48% and 19% for stage N0 and 54%, 25% and 3% for stage N+, respectively, with corresponding median survivals of 20 and 12 months (p < 0.005). The recurrence rate increased from 40% at stage N0 to 62% at stage N+ (p = 0.05), and the corresponding recurrence-free survivals were 16 months and 7 months (p < 0.02). The median survival without chemotherapy ranged from 11 months at stage N+ to 20 months at stage N0 and, with chemotherapy, from 19 months at stage N+ to 67 months at stage N0. The median recurrence-free survival with and without chemotherapy, was 43 months and 17 months at stage N0 and 12 months and 7 months at stage N+.
  
  
  CONCLUSIONS
  The prognosis after cystectomy for stage pT3b bladder cancer is severe, especially in the presence of lymph node involvement. Adjuvant chemotherapy according to the MVAC protocol tends to improve survival, especially recurrence-free survival, and appears beneficial at stage N0. However, the value of this adjuvant treatment, which is associated with a high specific morbidity appears to be more relative at stage N+.
