  1. Prospective study of sex hormone levels and risk of prostate cancer.

    Article - En anglais


    Sex steroids, particularly androgens, have been implicated in the pathogenesis of prostate cancer.

    Data from previous studies comparing circulating hormone levels in men with and without prostate cancer are difficult to interpret, since the studies were limited in size, hormone levels were analyzed in blood drawn after the diagnosis of cancer, nonrepresentative control subjects were used, and hormone and hormone-binding protein levels were not simultaneously adjusted.


    We conducted a prospective, nested case-control study to investigate whether plasma hormone and sex hormone-binding globulin (SHBG) levels in healthy men were related to the subsequent development of prostate cancer.


    Among participants in the Physicians'Health Study who provided plasma samples in 1982, we identified 222 men who developed prostate cancer by March 1992.

    Three hundred ninety control subjects, matched to the case patients on the bases of age, smoking status, and length of follow-up, were also identified.

    Immunoassays were used to measure the levels of total testosterone, dihydrotestosterone (DHT), 3alpha-androstanediol glucuronide (AAG), estradiol, SHBG, and prolactin in the stored (at - 82 °C) plasma samples.

    Correlations between individual hormone levels and between hormone levels and SHBG in the plasma of control subjects were assessed by use of Spearman correlation coefficients (r). (...)
