Neoadjuvant M-VAC (methotrexate, vinblastine, doxorubicin and cisplatin) for extravesical urinary tract tumors.
A total of 11 patients with stage T2-4N0M0 extravesical tumors (prostate, prostatic urethra, urethra and ureter) received 1 to 4 cycles of neoadjuvant methotrexate, vinblastine, doxorubicin and cisplatin. Of 10 evaluable patients 4 (40 per cent) had downstaging to T0 disease with a clinical complete remission observed in 3 of 5 (60 per cent) with transitional cell tumors of the prostate and prostatic urethra. Four patients with urethral tumors of mixed or nontransitional histology failed to achieve a complete remission. The disease was staged pathologically in 4 patients: 1 had a partial remission and 3 had progression (all 4 had residual disease). Because therapy with methotrexate, vinblastine, doxorubicin and cisplatin induced only significant tumor regression of transitional cell elements of extravesical tumors and because it was ineffective against mixed histological tumors and in preventing new stage Tis lesions, surgical resection of such lesions is required.
