Abstract

Objective To analyze the expression of estrogen (ER) and progesterone (PR) receptors in the smooth muscle component (SMC) of deep infiltrating endometriosis (DIE).Design A prospective clinical and pathologic study of 60 cases of DIE.Setting University Hospital Department of Gynacology.Patient(s) Sixty patients with symptomatic DIE (uterosacral endometriosis n = 14; bladder endometriosis n = 10; colonic endometriosis n = 16; rectovaginal endometriosis n = 20).Intervention(s) Laparoscopic surgery.Main outcome measure(s) The expression of ER and PR was studied by immunohistochemistry in the SMC directly around endometriotic foci and at distance (at least >1.5 cm) from them in correlation with proliferative and secretory phases of cycle.Results The ER and PR were present in the SMC of DEI in each location excepting colonic endometriosis where ER were absent. Independently of cycle's phases the PR were more abundant than ER. With the exception of rectovaginal endometriosis, where the ER and PR were more abundant in the proliferative than in the secretory phase, in other locations the ER and PR did not differ significantly with cycle's phases. Last, if ER and PR were more abundant in SMC around endometriotic foci than at a distance from them. However, the difference was not significant.Conclusions Our data substantially confirm for the first time that in various forms of DIE, ER and PR are present not only in glands and stroma but also in the smooth muscle major histologic component of this disease.

  • Progesterone receptors are present in major histologic components of colon endometriosis, including the smooth muscle fibers.

    “Noël et al . demonstrated that progesterone receptors were present in major histologic components of colon endometriosis, including the smooth muscle fibers (45).”
  • The receptor pattern and biologic behaviour of eutopic and ectopic endometrium are substantially similar.

    “the receptor pattern and the biologic behaviour of the two mucosae are substantially similar (Noel et al., 2010)”
  • Endometriosis appears to originate from intrauterine endometrium.

    “endometriosis appears to originate from intrauterine endometrium”
  • ERs and PRs are present not only in glands and stroma but also in the smooth muscle component of deep endometriosis, and the expression of a-smooth muscle actin and collagen I in and around endometriotic lesions support the notion of the metaplastic process.

    “That E receptors (ERs) and PRs are present not only in glands and stroma but also in the smooth muscle component of deep endometriosis (229), and the expression of a-smooth muscle actin and collagen I in and around endometriotic lesions support the notion of the metaplastic process (230).”

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.
