Summary

This trial is testing whether a soy-based pill called genistein can help reduce side effects and improve the effectiveness of bladder cancer treatment. It targets patients with non-muscle invasive bladder cancer who are undergoing BCG therapy. Genistein may reduce inflammation and boost the immune system, making the treatment more comfortable and effective. Genistein, a soy compound, has been observed to inhibit bladder cancer growth.

Who is the study for?
This trial is for adults with non-invasive bladder cancer scheduled for BCG therapy. Participants must be willing to give blood samples, maintain a pill diary, and consent to the study. It's not open to pregnant individuals, those unwilling to follow the protocol, with concurrent second active cancer, muscle-invasive bladder cancer, or compromised immune systems.
What is being tested?
The study tests if genistein (a soybean chemical) can reduce urinary tract symptoms from intravesical therapy in bladder cancer treatment compared to a placebo (sugar pill). Patients are randomly assigned to either take genistein or placebo over approximately four and a half months.
What are the potential side effects?
While specific side effects of genistein aren't detailed here, it's generally being tested for its potential benefits on urinary symptoms related to bladder cancer treatments rather than adverse effects.

Other Research
Common treatments for bladder cancer include intravesical therapy, chemotherapy, and emerging agents like genistein. Intravesical therapy involves directly administering therapeutic agents into the bladder to target cancer cells locally, reducing systemic side effects. Chemotherapy, often using agents like cisplatin, works by damaging the DNA of rapidly dividing cancer cells, leading to cell death. Genistein, a soy-derived compound, is being studied for its potential to reduce lower urinary tract symptoms and impact recurrence rates by modulating cellular pathways involved in cancer progression. These treatments are crucial for bladder cancer patients as they aim to effectively manage the disease while minimizing adverse effects and improving quality of life.

I was a patient of Dr. Kucuk in 2005 and found him to be very comprehensive in his treatments and explanations. He always had time for questions, and when I was feeling down, he was always able to lift my spirits.
