This study investigated the association between endometriosis and ovarian cancer, particularly its clear-cell and endometrioid subtypes, addressing limitations of previous research regarding statistical power and diagnostic accuracy.

This thesis investigated the associations between proven endometriosis or adenomyosis and cancer outcomes in over 133,000 women. Using population-level data, it found that women with proven endometriosis or adenomyosis had an increased risk of developing ovarian or endometrial cancer. The thesis also reported that overall survival after ovarian or endometrial cancer diagnosis was better for women with endometriosis or adenomyosis than for women without, and that after removal of the ovaries in women with endometriosis, the extra-ovarian cancer risk decreased to below population extra-ovarian cancer risk. This paper is centrally about endometriosis and adenomyosis—quantifying their association with ovarian and endometrial cancer risk and survival.

Abstract

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

Abstract

Endometriosis and adenomyosis are benign diseases in which the tissue that normally lines inside of the uterus (endometrium) is present in the muscle layer of the uterus (adenomyosis), on the ovaries or in the abdominal cavity (endometriosis). Previously published studies have shown a possible association between endometrioses/adenomyosis and cancer. Therefore, this thesis studied these associations in over 133,000 women with proven endometriosis or adenomyosis. This thesis shows that women with proven endometriosis or adenomyosis have an increased risk of developing ovarian or endometrial cancer. However, the overall survival after ovarian or endometrial cancer diagnosis in women with endometriosis/adenomyosis when compared to women without endometriosis/adenomyosis is better. Also, the thesis found that after removal of the ovaries in women with endometriosis, the extra-ovarian cancer risk reduces to less than the population (extra-)ovarian cancer risk. | Original language | English | |---|---| | Awarding Institution | - Maastricht University | | Supervisors/Advisors | - Bekkers, Ruud, Supervisor - van Altena, Anne M., Co-Supervisor, External person - Siebers, Albert G., Co-Supervisor, External person | | Award date | 27 Jun 2022 | | Place of Publication | Maastricht | | Publisher | | | Print ISBNs | 9789464582895 | | DOIs | | | Publication status | Published - 2022 |
