  Purpose

RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. The use of high-dose multivitamins may be an effective way to prevent the recurrence of early stage bladder cancer. It is not yet known whether high-dose vitamins are more effective than no further therapy in decreasing the risk of early-stage bladder cancer.

PURPOSE: Randomized double-blinded phase III trial to compare the effectiveness of high-dose multivitamins with a placebo in preventing the recurrence of cancer in patients with early stage bladder cancer.

Estimated Enrollment: 360
Study Start Date: October 1999
Detailed Description:

OBJECTIVES: I. Determine whether high dose multivitamins have chemopreventive efficacy beyond standard therapy in reducing the risk of recurrence in patients with resected stage 0 and I (Ta, T1, and Tis) transitional cell carcinoma of the bladder.

OUTLINE: This is a randomized, double blind study. Patients are randomized to receive multivitamins or placebo orally once daily for 3 years. Patients are followed every 3 months for 2 years, then every 6 months for 1 year, and then annually thereafter.

PROJECTED ACCRUAL: A total of 360 patients (180/arm) will be accrued for this study within 3 years.
