Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

OBJECTIVE: 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.
