abstract
Between February 1988 and March 1993, 24 patients with locally advanced bladder cancer (stages T2-4N0-3M0) were included in this study. Combination chemotherapy consisting of methotrexate, vinblastine, epirubicin (doxorubicin) and cisplatin (M-VAC) was given to the patients in a neoadjuvant setting.  

The clinical stage was T2N0M0 in eight patients, T3aN0M0 in three, T3bN0M0 in seven, T4N0M0 in five and T4N3M0 in one. After chemotherapy, total cystectomy was performed in 20 patients and partial cystectomy 4. Of 24 patients, one (4%) showed a pathological complete response, and eight (33%) had a pathological partial response, for an overall response rate of 38% (95% confidence limits 20 to 57%). Nine patients who achieved a pathological response to chemotherapy had a significantly higher survival rate than the nonresponders (p<0.01). In the relationship between the clinical stage and the response to chemotherapy, clinical T2 and T3a diseases were more likely to respond to chemotherapy than clinical T3b and T4 diseases, with a response rate of 64% and 15%, respectively. While a positive relationship between the pathological response and survival was observed, adequate follow-up is needed to assess the ability of neoadjuvant chemotherapy to improve the prognosis of patients with locally advanced bladder cancer.
