Abstract

Endometrial carcinoma, especially endometrioid endometrial adenocarcinoma, is an estrogen-dependent tumor that is similar to breast cancer. Androgen is closely associated with other steroid hormones, but its correlation with endometrioid endometrial adenocarcinoma remains largely unclear. We previously demonstrated the expression of the androgen receptor, 5α-reductase type 1, and 5α-reductase type 2 in endometrioid endometrial adenocarcinoma tissue, but androgen action and its correlation with prognosis are unknown. In this study, we measured the tissue and serum concentrations of androgen and performed immunohistochemical analyses of androgen-associated factors in 41 patients. In 86 additional patients, we performed the same immunohistochemical analyses to identify correlations associated with prognosis. We found that 5α-reductase type 1 was associated with intratumoral dihydrotestosterone concentrations, and it was an independent prognostic factor in endometrioid endometrial adenocarcinoma. The poor prognosis of patients negative for both androgen receptor and 5α-reductase type 1 suggests that androgens have inhibitory effects on tumor growth.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Expression of 5αR1 (in 65% of samples) is positively correlated with histological grade in endometrial cancer.

    “concluding that expression of 5αR1 (65% of samples) was positively correlated with histological grade (but not clinical grade).”
  • Women immunonegative for both androgen receptor (AR) and 5αR1 have a poorer prognosis.

    “They found that women immunonegative for both AR and 5αR1 had a poorer prognosis [87]”
  • Expression of 5αR1 is not correlated with clinical grade in endometrial cancer.

    “concluding that expression of 5αR1 (65% of samples) was positively correlated with histological grade (but not clinical grade).”
  • Endometrial cancer tissues have an 8-fold elevation in dihydrotestosterone (DHT) compared with normal endometrial tissues.

    “it is notable that a study by the same group revealed that EC tissues had an 8-fold elevation in DHT compared with that in normal endometrial tissues [87].”

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.
