ClinConnect Summary
Genistein is a natural product found in soy beans; its consumption has been associated with a low incidence of metastatic prostate cancer. Genistein is a known protein-tyrosine kinase inhibitor, and in preclinical studies it has been shown to increase cell adhesion. Increases in cell adhesion in vivo would phenotypically reverse the first step in the metastatic cascade, potentially preventing metastasis formation, and is consistent with epidemiologic findings. This study seeks to determine the pharmacokinetics of genistein in humans by administering a single dose of genistein and performing...

Eligibility criteria
- • Must be 18 years old or greater.
- • ECOG performance status of 0-1.
- • Individuals without a history of cancer are eligible, as are those with a history of cancer. Individuals with a history of cancer (excluding non-melanomatous skin cancer ) will need to submit their pathology slides for review in the Laboratory of Pathology, NCI.
- • Must be able to understand and give informed consent.
- • Life expectancy greater than 6 months.
- • Hgb greater than or equal to 8.0gm/dl, platelets greater than or equal to 100,000/microliters, ANC greater than or equal to 1000/microliters, creatinine less than or equal to 2.0/mg/dl, SGPT and SGOT less than or equal to 147 and 168 U/L, total bilirubin less than or equal to 2 mg/dl (patients with a higher level of bilirubin due to a familial defect in bilirubin metabolism will be considered on an individual basis).
- • No history of breast cancer.
- • No pregnant or breast feeding subjects.
- • Must not be HIV positive.
- • No history of venous thrombosis within the past year.
- • No medical conditions, which, in the opinion of the investigators would jeopardize either the patient or the integrity of the data obtained.
- • No patients who are currently receiving active therapy for neoplastic disorders. However, patients with prostate cancer who are on an LHRH agonist (e.g., Lupron or Zoladex), or who have undergone surgical castration, are eligible for study.
- • No patients who are on estrogen therapy.
- • No patients taking hormonal forms of contraception.
- • No patients with a known soy intolerance.
