Adverse events of MVAC chemotherapy in patients with advanced urothelial cancer of the bladder.

There have only been a few reports about adverse events of methotrexate, vinblastine, adriamycin and cisplatin (MVAC) chemotherapy under supportive care with granulocyte stimulating factor (G-CSF) and 5-hydroxytryptamine 3 receptor (5-HT3R) antagonists. The purpose of this study was to retrospectively review the adverse events of the chemotherapy. We analyzed 59 patients with advanced bladder cancer who received MVAC chemotherapy at Sapporo Medical University hospital from January 1992 to September 2004. The adverse events were evaluated according to the Common Terminology Criteria for Adverse Events version 3.0 (Japanese edition). Thirty-one of the 59 patients (52.6%) received MVAC in the neoadjuvant setting. Two courses of chemotherapy were most frequently used in the neoadjuvant and adjuvant settings, and treatment of metastatic or recurrent lesions. More than 90% of patients experienced hematological adverse events such as some grade of leukocytopenia and neutropenia in each course of the chemotherapy. Grade 3 or 4 neutropenia was seen in 60-75% of patients. Grade 3 or 4 leukopenia and/or neutropenia in the first course of the chemotherapy was associated with patients with impaired renal function (60 mL/min< or = creatinine clearance <80 mL/min). Febrile neutropenia was found in 6 patients (5.0%), including one who died of subsequent septic shock and adult respiratory distress syndrome. Nausea was seen in 70-80% of patients. MVAC chemotherapy for advanced bladder cancer was performed with tolerable adverse events. The current results provide relevant information mainly for those who need 2 courses of chemotherapy in the neoadjuvant or adjuvant setting.
