Levels of plasma steroid glucuronides in intact and castrated men with prostatic cancer.

Abstract

The levels of plasma dehydroepiandrosterone (DHEA), androst-5-ene-3 beta,17 beta-diol (delta 5-diol), testosterone (T), dihydrostestosterone (DHT), androstane-3 alpha,17 beta-diol (3 alpha-diol), androsterone (ADT), and the related glucuronide (G) derivatives were determined in intact and castrated men with prostatic cancer. The plasma concentrations of DHEA and DHEA-G were not significantly different in intact and castrated men while delta 5-diol as well as delta 5-diol-G were 50% lowered in castrated men. As expected, T and DHT concentrations were markedly lower in castrated men. These low plasma levels of T and DHT were accompanied by a decrease of 3 alpha-diol, ADT, T-G, 3 alpha-diol-G, and ADT-G levels. There was, in unoperated men, a positive correlation between the levels of DHEA and ADT-G as well as DHEA and DHEA-G, while T values were highly correlated with ADT-G and 3 alpha-diol-G levels. Furthermore, a significant relationship was found between DHEA and ADT-G as well as 3 alpha-diol-G in castrated men. Our data clearly demonstrate that ADT-G and 3 alpha-diol-G levels are more affected by castration than are the corresponding unconjugated steroids and suggest that these steroid glucuronides should be good markers of androgen metabolism. Moreover, the significant relationship between DHEA, ADT-G, and 3 alpha-diol-G in castrated men also suggests that approximately 30% of C-19 steroids from the adrenals are converted to T and DHT, which are further transformed into steroid glucuronides.

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.
