✦ Synopsis

One of the most intriguing features of prostate cancer epidemiology is the marked international and racial-ethnic variation in risk. There is a 30-50-fold difference in risk between African American men, at the highest end of this racial-ethnic spectrum of risk, and native Japanese and Chinese men, at the lowest end of this spectrum. Because of their important growth regulatory effects on prostate cells, there has been widespread interest in the role of androgens in prostate cancer pathogenesis. The authors have been evaluating systematically whether population variations in secretion and metabolism of androgens and/or regulation of androgen activity can explain the marked racial-ethnic diversity in prostate cancer incidence. Differences in hormonal patterns among groups have been demonstrated in a manner predicted by their underlying prostate cancer incidence, and a series of studies have been initiated to determine if genetic control of androgen regulation among racial-ethnic groups also may be important in determining prostate cancer risk.

## Background: Elevated prostatic dihydrotestosterone (dht) has been suggested to increase the risk of prostate cancer. the hsd3b2 gene encodes the type ii 3 beta-hydroxysteroid dehydrogenase: one of two enzymes that initiate the inactivation of dht. thus, the hsd3b2 gene is a candidate gene for pr

## Abstract Accumulating epidemiological evidence suggests that sex steroid hormones are positively associated with the development of breast cancer. However, most of these studies were conducted among Caucasian women and few have been carried out in China. To determine whether the associations of
