Abstract

Objective To determine the clonal origins of endometriotic lesions using laser capture microdissection and PCR-based HUMARA assay.Design Molecular genetic study of human tissue.Setting Molecular genetics laboratory in an academic setting.Patient(s) Twenty patients with endometriosis. Forty specimens of endometriotic lesions from these patients and one specimen of normal endometrium were analyzed.Intervention(s) Laser capture microdissection was used to harvest epithelial cells from single and multifocal endometrial lesions from paraffin-embedded and frozen tissues, and their clonality was determined with the HUMARA assay.Main outcome measure(s) Polymerase chain reaction-based HUMARA assay of clonality.Result(s) Thirty-eight specimens were polymorphic and thus informative. Most specimens were monoclonal, as determined by the HUMARA assay. In four specimens of multifocal lesions, polyclonality was detected, but upon more refined microdissections and further analyses, we found that each focus was monoclonal individually.Conclusion(s) Previously reported polyclonality is very likely to be attributed to the pooling of multifocal lesions or contamination of normal tissues. These results suggest that endometriotic lesions were monoclonal in origin, and in the case of multifocal lesions, each focus originates monoclonally; hence, different foci have independent origins. The monoclonality of endometriotic lesions suggests that they may carry neoplastic potentials, and the apparent independent origins of multifocal lesions suggest that reconstruction of individual lesion histories may help us to understand the initiation and progression of endometriosis.

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

  • Endometriosis lesions are clonal, as demonstrated for typical, deep, and cystic ovarian endometriosis.

    “Endometriosis lesions are clonal, as demonstrated for typical (149), deep (150), and cystic ovarian (151-153) endometriosis.”

    From Pathogenesis of endometriosis: The genetic/epigenetic theory (2019) · cites this paper as [149]

  • Deep and cystic ovarian endometriosis are consistently found to be clonal in origin.

    “A strong argument is that deep (174, 175) and cystic (176-178) ovarian endometriosis are consistently found to be clonal in origin.”

    From Pathogenesis of deep endometriosis (2017) · cites this paper as [175]

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.
