ABSTRACT

The Authors report the results with combination of cisplatin, methotrexate, vinblastine with adriamycin or epidoxorubicin (MVAC v MVEEC), in the neoadjuvant treatment of muscle-infiltrating bladder cancer (T2-4NO-1MO), before cystectomy. MVAC has been used in 29 patients and MVEEC in 25, who met eligibility criteria. Results from this prospective randomised trial show that MVAC and MVEEC can produce clinical and pathologic down-staging in 40-50% of cases cCR+cPR are 15/28 (54%), pCR+pPR are 11/25 (44%). The survival duration of "pathologic" responders has been significantly longer than that of no responders (median no achieved at 200 weeks v 124 weeks for "pathologic" no responders). We conclude that neoadjuvant chemotherapy with MVAC or MVEEC select the more responsive patients, who have a longer survival.
