Abstract

Endometriosis is a common condition in women of reproductive age. According to several epidemiological studies endometriosis may be associated with increased risk of various malignancies. However, endometriosis-associated malignancy (EAM) is defined by certain histological criteria. About 80 % of EAM have been found in the ovary, whereas 20 % are localized in extragonadal sites like intestine, rectovaginal septum, abdominal wall, pleura and others. Some authors suggest that EAM arise from atypical endometriosis as an intermediate lesion between endometriosis and cancer. Moreover, a number of genetic alterations, like loss of heterozygosity (LOH), PTEN, ARID1 A and p53 mutations have been found in both endometriosis and EAM. Endometriosis-associated ovarian cancer (EAOC) is mostly a well or intermediately differentiated tumor of endometrioid or clear cell histological sub-type. Women affected by EAOC are on average five to ten years younger than non-EAOC patients; in most of the cases EAOC is a low stage disease with favorable clinical outcome. Since EAM is a rare condition systematic data on EAM are still missing. A systematic retrospective study on endometriosis-associated malignancies (EAM study) is currently being conducted by the Endometriosis Research Foundation together with the study groups on ovarian and uterine tumors of the working group for gynecological oncology (AGO) (gyn@mlk-berlin.de).

  • Endometriosis is significantly associated with an increased risk of clear cell, low-grade serous and endometrioid invasive cancers.

    “Endometriosis was significantly associated with an increased risk of clear cell, low-grade serous and endometrioid invasive cancers [35].”

    From Malignancy in Abdominal Wall Endometriosis: Is There a Way to Avoid It? A Systematic Review (2024) · cites this paper as [35]

    The review’s discussion of ovarian cancer subtypes (page unavailable) says endometriosis-associated malignancies are most commonly endometrioid and clear cell carcinomas, and reports a statistically significant increased risk of low-grade serous ovarian cancer. Our copy does not give subtype-specific statistical evidence for an increased risk of clear cell or endometrioid invasive cancers, so the claim’s significance qualifier is not fully supported for all three types.

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.
