Long-term follow-up results of a Pilot Phase II study of multidrug chemotherapy (MVP-CAB) in patients with advanced urothelial cancer.
BACKGROUND
To determine the long-term effects and toxicity of multidrug chemotherapy for advanced urothelial cancer.


METHODS
Forty patients with metastatic urothelial cancer were treated with a new combination chemotherapy, MVP-CAB (methotrexate, doxorubicin, vincristine, cyclophosphamide, bleomycin and cisplatin every 28 days). Of the 40 patients, 26 had not undergone prior chemotherapy or radiotherapy; the remaining 14 patients had undergone prior cisplatin-based chemotherapy.


RESULTS
The clinical response rate to MVP-CAB therapy for all 40 patients was 63% [complete response (CR), six patients; partial response (PR), 19 patients]. The median duration of the effects was 22 and 13 months in the patients with CR and PR, respectively. The clinical response rate for the 26 patients without prior chemotherapy was 77% (CR, four patients; PR, 16 patients). The rate for the 14 patients with prior chemotherapy was 36% (CR, two patients; PR, three patients). The response rate according to metastatic site was highest for the liver (80%), followed by the lymph nodes (74%) and lungs (67%). The effect on bone metastasis was poor (22%). There was good compliance with the MVP-CAB chemotherapy regimen and toxicity was tolerable. The 1-, 3- and 5-year overall survival rates were 42.5, 10 and 5%, respectively.


CONCLUSIONS
MVP-CAB combination chemotherapy was found to be effective for the treatment of advanced urothelial cancer, especially for liver metastasis.
