The purpose of our study is to recruit and treat 260 men diagnosed with prostate cancer and scheduled for a prostatectomy with a capsule form of either purified isoflavones or placebo for a 4-6 week period to see if we can slow down the rate of prostate cancer growth. A placebo is a pill or something that looks like the medicine that is being studied but has no active medicine in it. We also want to see if taking purified isoflavones is safe and if it reduces lower urinary tract symptoms. In addition, we want to study if purified isoflavones are able to slow the progression of prostate cancer, and the mechanism of action of purified isoflavones. If the safety and the effects of purified isoflavones on slowing down the progression of prostate cancer is shown in our study, this will also be a safe way of treating men who are at high risk of prostate cancer, so that we can prevent prostate cancer in the future.
Patients will need to take two (2) capsules daily, one with their breakfast and one with their dinner. On the day prior or the day that patients are coming in for their pre-operative surgery blood work, we ask that they take the second dose with lunch, if their appointment is in the afternoon.
At the start of the study and at the end of the study (4-6 weeks), patients will undergo interviews, complete questionnaires, and have lab tests to determine if this drug is effective to reduce progression of prostate cancer and is safe to use.
Patients will also receive a multivitamin/mineral supplement for the 4-6 weeks that they are on this study and will be required to take one (1) every day. It is required that patients not take any other vitamin/mineral or herbal preparation containing isoflavones and avoid eating or drinking soy products.
We anticipate that most patients will be scheduled for a prostatectomy 4-6 weeks after the initial diagnosis. In addition to their first visit, patients will be required to come in the day of the surgery for prostatectomy.

The role of testosterone in the development of prostate cancer and the safety of testosterone therapy (TTh) after prostate cancer treatment, or in the setting of active surveillance, remains controver...
Vitamin K inhibits prostate cancer cells, and an altered expression of vitamin K-dependent proteins in prostate tumors has been linked to their aggressiveness and progression. However, little is known...
Prostate cancer is one of the most commonly diagnosed malignancies among men in Western populations. Evidence reported in the literature suggests that zinc may be related to prostate cancer. In this s...
The current praxis of diagnosing prostate cancer, with systematic prostate biopsies in men with raised serum prostate-specific antigen (PSA) levels, leads to considerable over-diagnosis and over-treat...
Cannabinoids have demonstrated anticarcinogenic properties in a variety of malignancies, including in prostate cancer. In the present study, we explored the anti-cancer effects of the synthetic cannab...
A glycoprotein that is a kallikrein-like serine proteinase and an esterase, produced by epithelial cells of both normal and malignant prostate tissue. It is an important marker for the diagnosis of prostate cancer.
A synthetic retinoid that is used orally as a chemopreventive against prostate cancer and in women at risk of developing contralateral breast cancer. It is also effective as an antineoplastic agent.
Tissue ablation of the PROSTATE performed by ultrasound from a transducer placed in the RECTUM. The procedure is used to treat prostate cancer (PROSTATIC NEOPLASMS) and benign prostatic hypertrophy (PROSTATIC HYPERPLASIA).
Proteins secreted by the prostate gland. The major secretory proteins from the human prostate gland include PROSTATE-SPECIFIC ANTIGEN, prostate-specific acid phosphatase, prostate-specific membrane antigen, and prostate-specific protein-94.
