OBJECTIVE: To assess the prevalence of obstetric and neonatal complications in pregnancies of women with histologically confirmed endometriosis, adenomyosis, or both, compared with the general Dutch population. METHODS: In this retrospecti…

Abstract Study question What is the prevalence of obstetric/neonatal complications in pregnancies of women with histopathologic confirmed endometriosis, adenomyosis, or both, versus that of the general (Dutch) population? Summary answer Wom…

OBJECTIVE: To assess the incidence of ovarian cancer in women with histologically proven endometriosis after bilateral salpingo-oophorectomy (BSO). DESIGN: Retrospective nationwide cohort study. SETTING: Dutch pathology database. PATIENT…

BACKGROUND: Adenomyosis is a benign gynecologic condition arising from the uterine junctional zone. Recent studies suggest a relationship between adenomyosis and adverse obstetrical outcomes, but evidence remains conflicting. There is no la…

Women with histologically proven endometriosis/adenomyosis have an increased risk of ovarian cancer. Small studies show conflicting results on the endometrial cancer risk in women with endometriosis/adenomyosis. Therefore, we assessed the i…

We aim to compare endometrial cancer survival in women with or without histological proven endometriosis or adenomyosis. We identified all women with endometrial cancer between 1990 and 2015 from the Netherlands Cancer Registry (NCR). Data …

OBJECTIVE: Assessing the association between endometriosis and/or adenomyosis and ovarian cancer. METHODS: We identified all women with histological proven endometriosis (51,544 women) and/or adenomyosis (85,015 women) from the Dutch patho…

BACKGROUND: Several studies have suggested that endometriosis is associated with an increased risk of ovarian cancer, especially for the clear-cell and endometrioid subtypes. However, previous studies lack sufficient power or diagnostic cer…

BACKGROUND: Few studies have investigated the possible association between endosalpingiosis and ovarian cancer, therefore we assessed whether there is an association between histological confirmed endosalpingiosis and ovarian cancer. METHO…

BACKGROUND: Contradicting results regarding ovarian cancer prognosis in women with endometriosis have been reported in the literature. Owing to the small sample size of previous studies, larger studies are required to elucidate the role of …
