Incidence of ovarian cancer after bilateral salpingo-oophorectomy in women with histologically proven endometriosis.

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.

Endometrial cancer prognosis in women with endometriosis and adenomyosis: A retrospective nationwide cohort study of 40 840 women.

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 were linked to the Dutch pathology database (PALGA) to select all women with histological proven endometriosis/adenomyosis.

Endometrial Cancer Incidence in Endometriosis and Adenomyosis.

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 incidence of endometrial cancer in women with histologically proven endometriosis or adenomyosis.

Increased incidence of ovarian cancer in both endometriosis and adenomyosis.

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 pathology database (1990-2015) and matched with women with a benign dermal nevus (132,654 women). Histology results for ovarian cancer were retrieved.

Immunologic factors involved in the malignant transformation of endometriosis to endometriosis-associated ovarian carcinoma.

Introduction: Endometriosis is a risk factor for low-grade serous, clear cell, and endometroid ovarian carcinoma. In both endometriosis and ovarian carcinoma, immunological factors are associated with clinical outcome. Chronic inflammation in endometriosis may be linked to tumorigenesis, but exact processes contributing to endometriosis-associated ovarian carcinoma remain unknown.
