Comparison of Immediate and Delayed Adjuvant Chemotherapy in Treating Patients Who Have Undergone a Radical Cystectomy for Stage III or Stage IV Transitional Cell Carcinoma of the Bladder Urothelium

Phase 3

Completed

• Conditions: Stage III Bladder Cancer; Stage IV Bladder Cancer; Transitional Cell Carcinoma of the Bladder
• Interventions: Drug: doxorubicin hydrochloride; Drug: gemcitabine hydrochloride; Drug: vinblastine sulfate; Drug: methotrexate; Drug: cisplatin; Biological: filgrastim

• Registration Number: NCT00028756
• Lead Sponsor: European Organisation for Research and Treatment of Cancer - EORTC

Brief Summary

Randomized phase III trial to compare the effectiveness of immediate adjuvant chemotherapy with that of adjuvant chemotherapy given when the cancer returns in treating patients who have undergone a radical cystectomy for stage III or stage IV transitional cell carcinoma of the bladder urothelium. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug and giving them after surgery may kill any remaining tumor cells. It is not yet known if adjuvant chemotherapy is more effective when given immediately after radical cystectomy (surgery to remove the bladder) or when the cancer returns.

Detailed Description

PRIMARY OBJECTIVES:

I. Compare the overall and progression-free survival of patients with stage III or IV transitional cell carcinoma of the bladder urothelium treated with immediate versus deferred adjuvant chemotherapy after radical cystectomy.

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to participating center, tumor status (pT1-2 vs pT3 vs pT4), and node status (node positive vs node negative with 15 or more nodes sampled vs node negative with less than 15 nodes sampled). Patients are randomized to one of two treatment arms.

ARM I: Beginning within 90 days of radical cystectomy, patients receive a total of 4 courses of adjuvant chemotherapy.

ARM II: Beginning at the time of clinical relapse, patients receive a total of 6 courses of adjuvant chemotherapy.

Patients in both arms receive one of the following chemotherapy regimens to be determined by participating center:

REGIMEN A (Classical M-VAC): Patients receive classical M-VAC comprising methotrexate IV on days 1, 15 and 22; vinblastine IV on days 2, 15, and 22; and doxorubicin IV and cisplatin IV on day 2. Courses repeat every 28 days.

REGIMEN B (High-dose M-VAC): Patients receive high-dose M-VAC comprising methotrexate IV on day 1 and vinblastine IV, doxorubicin IV, and cisplatin IV on day 2. Patients also receive filgrastim (G-CSF subcutaneously once daily on days 4-10. Courses repeat every 14 days.

REGIMEN C (Gemcitabine and cisplatin): Patients receive gemcitabine IV over 30 minutes on days 1, 8, and 15 followed by cisplatin IV on day 1 or 2. Courses repeat every 28 days.

Patients are followed every 3 months for 1 year, every 6 months for 5 years, and then annually thereafter.
