Systemic preoperative chemotherapy with cisplatin, methotrexate and vinblastine for locally advanced bladder cancer: local tumor response and early followup results.
A total of 44 patients with infiltrating, locally advanced bladder cancer (stages T 3a-b, T 4a-b and N+/N0) were treated with the systemic chemotherapy regimen of cisplatin, methotrexate and vinblastine (CMV) in the neoadjuvant setting, of whom 39 were evaluable for response. After planned radical cystectomy and 2 to 3 cycles of chemotherapy no tumor was found on the pathological specimen of 4 patients (10%), the tumor was downstaged in 19 (49%) and no change was observed in 16 (41%). Toxicity included leukopenia in 29 patients (66%), 1 of whom died of granulocytopenic sepsis, nausea and vomiting in 39 (89%) and mild to moderate mucositis in 18 (41%). Median followup is 12 months with a range of 6 to 39 months. Of 32 patients followed for longer than 6 months 6 (19%) experienced progression or recurrence of disease. We conclude that preoperative CMV chemotherapy is effective in inducing downstaging of the tumor, although systemic toxicity limits its use to cautiously selected patients.
