Familial factors affecting prostatic cancer risk and plasma sex-steroid levels

Wayne Meikle, A., Smith, Joseph A., West, Dee W.·1985·The Prostate

Abstract

Whether familial factors affect the frequency of prostatic cancer and the plasma content of sex‐steroids was investigated. Brothers (n = 257) of probands (n = 150) diagnosed with prostatic cancer before age 62 years had a fourfold higher risk for developing the disease than men in the general population in the State of Utah and their brothers‐in‐law (n = 202). Familial factors markedly affected the plasma content of sex steroids (testosterone, dihydro‐testosterone, the ratio of testosterone to DHT, sex‐hormone binding globulin, and the free fraction of testosterone) in nonendocrinologically treated probands and their brothers and sons and in normal men in the general populations. Index cases and their brothers and sons had a significantly lower mean plasma testosterone content than controls of comparable age. Preliminary data suggest that the metabolic clearance rate of testosterone and the conversion ratio of testosterone to estradiol are relatively high in probands. The observations indicate that familial factors are potent risk factors for the development of prostatic cancer. They also suggest that plasma androgen values in families with prostatic cancer cluster in the lower range of normal and that plasma sex‐steroid content is more similar in each brothers with or without prostatic cancer than among nonbrothers.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
