title: [Neoadjuvant chemotherapy (M-VAC) for locally invasive bladder cancer].
abstract: Eight patients with locally invasive bladder cancer (stages T2-T4, N0, M0; 7 men and 1 woman; mean age, 72.0 years; age range, 56 to 80 years) were treated with 2 cycles of neoadjuvant chemotherapy consisting of methotrexate, vinblastine, adriamycin and cisplatin (M-VAC). Seven of them underwent radical cystectomy after chemotherapy, while the bladder was preserved in one patient. Seven patients were free of disease during a mean follow-up period of 26.2 months (range 20-30 months). However, one patient whose pathological stage was pT2, N1 died with disease 27 months after radical cystectomy. The patient whose bladder had been preserved showed no recurrence after a follow-up period of 27 months. Pathological examination of the resected specimen after chemotherapy revealed no tumor tissue in three patients; one with negative cytology and two with positive cytology. Downstages were observed in two patients. Results showed that the toxicity of neoadjuvant M-VAC therapy is acceptable and that M-VAC therapy is effective against locally invasive transitional cell carcinoma of the bladder. The problem remains of how to assess the clinical stage more accurately before chemotherapy and radical cystectomy.
