In addition to its estrogenic and/or antiestrogenic activities, genistein has been reported to inhibit steroidogenesis and block several protein tyrosine kinases, including epidermal growth factor receptor and src tyrosine kinases.

Such PSA relapses, conservatively estimated to affect approximately 50,000 men each year, have become the most common form of advanced prostate cancer. Salvage radiation therapy and salvage prostatectomy have important roles in our therapeutic armamentarium and should be valid options for young, healthy men. Counseling patients regarding expectations for cancer control and treatment morbidity has become better because of reports from larger series of patients who have had salvage radiation therapy and surgery. Some patients may not be appropriate candidates for salvage local therapies. A growing body of evidence suggests early hormonal therapy improves progression-free survival (PFS) and could alter cancer-specific survival. This benefit seems to be greatest when hormonal therapy is initiated while PSA levels are low, before clinically measurable disease becomes apparent. However, there is a cost to be paid in side effects and health care dollars when androgen deprivation is administered over prolonged periods. The nonsteroidal antiandrogen agent bicalutamide could offer PFS equivalent to that seen with castration without the complications of androgen deprivation. Observational data seem to indicate that individuals at high risk could also receive benefit from therapy administered before PSA detection.

Physicians have long sought to guide patients through these choices based on their best judgment about the threat posed by the cancer, the effectiveness of treatment, the side effects of therapy, and the life expectancy of the patient. Today, many patients wish to participate more actively in decisions about their care, weighing the risks of treatment-related complications and the anxiety of living with an untreated or uncontrolled cancer. Patient utilities measure the value patients place on a health state, such as living with cancer or becoming incontinent, allowing quantitative assessments of risks and benefits of different therapeutic options specific for each patient's own preferences and the nature of his cancer and life expectancy. As early detection programs for prostate cancer expand, men are being diagnosed with prostate cancer earlier in its natural history. Some of these cancers may not require immediate treatment but rather a period of active surveillance with definitive curative therapy being administered only if there are signs of cancer progression.
