Abstract

BACKGROUND: Endometriosis is an important women's health issue, however its aetiology remains unknown. An association between endometriosis and cutaneous melanoma was described, possibly explained through common genetic features. To further investigate this association, we assessed the link between phenotypic traits predisposing to melanoma and the risk of endometriosis. METHODS: Using a case-control design, we analysed data from 97,215 women of the Etude Epidémiologique auprès de femmes de l'Education Nationale study, a cohort of 98,995 French women insured by a national health scheme mostly covering teachers, and aged 40-65 years at inclusion in 1990. Risk estimates were computed using unconditional logistic regression models. RESULTS: After adjustment for potential confounding factors, there was a positive dose-effect relationship between risk of endometriosis (reported as surgically ascertained, n = 4241) and skin sensitivity to sun exposure [moderate: odds ratio (OR) 1.09, 95% confidence interval (CI) 0.99-1.19; high: OR 1.22; 95% CI 1.10-1.36; compared with none; Ptrend < 0.0001], number of naevi (few: OR 1.19, 95% CI 1.05-1.35; many: OR 1.37, 95% CI 1.21-1.55; very many: OR 1.59, 95% CI 1.37-1.83; compared with none; Ptrend < 0.0001) and number of freckles (few: OR 1.08, 95% CI 1.00-1.17; very many/many: OR 1.11, 95% CI 1.03-1.20; compared with none; Ptrend = 0.005). CONCLUSION: This study is, to our knowledge, the first to report a positive dose-effect relationship between the risk of endometriosis and skin sensitivity to sun exposure, and number of naevi and freckles. These data suggest that endometriosis and melanoma may share some genetic features.

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.
