Bladder Cancer Clinical Trial
Study of Genistein in Reducing Side Effects of Superficial Bladder Cancer Treatment
Patients with non-invasive bladder cancer are often treated with intravesical therapy in order to prevent the recurrence of bladder cancer. Intravesical therapy can cause many lower urinary tract symptoms, which can limit the dose of therapy and therefore efficacy of treatment. There have been a number of studies that suggest a chemical found in soy beans may be able to help with these side effects. This chemical is called genistein and can be extracted and given to study subjects in pill form. In this study, the investigators would like to have patients placed into two different groups. One group would take genistein and the other group would take a placebo, a sugar pill that looks like the genistein pill. In doing this study the investigators hope to explore the findings from other studies to see if lower urinary tract symptoms are reduced and to see if recurrence rates for patients are affected by genistein. The study would take about four and a half months total.
Patients who are treated with bacillus Calmette-Guerin (BCG) intravesical therapy for non-muscle invasive (TaT1) Tis superficial bladder cancer often develop adverse effects (urinary tract symptoms) which limit the dose (and therefore the efficacy) of therapy and result in poor quality of life. Genistein is a nutritional supplement with anti-inflammatory properties which might help alleviate adverse effects of intravesical therapy that are due to inflammation. Additionally, genistein also has anti-tumor and immunopotentiating properties and has been shown to have no known side effects. Our hypothesis is that genistein given together with BCG intravesical therapy will reduce its adverse effects and improve the efficacy of therapy. Patients (N=88) scheduled for intravesical therapy will be randomly assigned to take 30 mg tablets PO TID of genistein supplement (N=44) or placebo (N=44) during therapy and one month post therapy.
