Abstrakt: Objectives: The combination of carboplatin, methotrexate and vinblastine (M-CAVI) is an active and well-tolerated regimen for patients with bladder cancer who are ineligible for cisplatin-based regimens. We have prospectively randomized patients with locally advanced (T2-4 N0 M0) or locoregional (Tx N1 M0) bladder cancer suitable for subsequent surgical treatment to M-VAC or M-CAVI chemotherapy.
Methods: M-CAVI consisted of carboplatin (300 mg/m2 on day 1 and later adjusted to 4.5 mg/dl/min according to Calvert's formula), methotrexate (30 mg/m2 on days 1, 15 and 22) and vinblastine (3 mg/m2 on days 1, 15 and 22). After 3-4 cycles, the patients were assessed for surgical resection.
Results: To date, 60 patients have been included. There were 58 completely evaluable patients, 27 were randomized to M-VAC and 31 to M-CAVI. The overall response rates were similar for M-VAC (48%; confidence interval 95%, 26%-67%) and M-CAVI (45%; confidence interval 95%, 28%-62%). The pathological complete responses were similar for the M-VAC and M-CAVI regimens for both the group with locally advanced (27% vs 39%, p = NS) and locoregional (14% vs 14%, p = NS) bladder cancer. The median actuarial survival for the M-VAC treated group was 23 months and 18 months for the M-CAVI. M-VAC therapy was statistically significantly associated with more events of granulocytopenic fever, grade 2-3 nausea and vomiting, grade 2 alopecia and grade 3-4 mucositis.
Conclusions: The results achieved in the 60 patients included in the study indicate that M-CAVI is better tolerated than M-VAC, although both treatment regimens have similar overall response rates, pathological response rates and survival in patients with locally advanced and locoregional bladder cancer.
