A Cruciferous Vegetable Eating Program for the Reduction of Cancer Recurrence and Progression in Patients With Non-muscle Invasive Bladder Cancer

United States344 participantsStarted 2026-01-13

Plain-language summary

This phase II trial is being done to develop and test a healthy eating program to reduce cancer recurrence (cancer that has come back after a period of improvement) and/or progression (cancer that is growing, spreading, or getting worse) in patients with non-muscle invasive bladder cancer (NMIBC). Researchers want to better understand how incorporating more cruciferous vegetables in the diet may reduce the risk of cancer recurrence or progression in men and women who were diagnosed with early-stage bladder cancer and compare whether extending the program can further improve bladder cancer outcomes. POW-R Health is a behavioral dietary intervention designed to modestly increase cruciferous vegetable (cruciferae) intake in patients. Cruciferous vegetables, such as cabbage, kale and broccoli, arugula, contain phytochemicals known as isothiocyanates (ITCs). Dietary ITCs exert potent anticancer activities against bladder cancer and can be rapidly metabolized, delivered to the bladder, and concentrated in the urine. Participating in the healthy eating program may reduce bladder cancer recurrence or progression in NMIBC survivors.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
