Delayed diagnosis of ovarian cancers favors BSO
“The question of removing ovaries at the time of benign hysterectomy to prevent ovarian cancer in low-risk women has been widely debated,” which has contributed to the variation in incidence rates of unilateral and bilateral oophorectomy over time, wrote Elizabeth Casiano Evans, MD, of the University of Texas, San Antonio, and Deslyn T.G. Hobson, MD, of Wayne State University, Detroit, in an accompanying editorial.
Ovarian cancer often goes undiagnosed until an advanced stage, and BSO can significantly reduce risk in women with BRCA1 and BRCA2 mutations, they noted.
For women without increased risk, those who are premenopausal may wish to preserve ovarian function, but women also may benefit from improvements in a range of menopause-related symptoms including vasomotor and urogenital symptoms, sexual dysfunction, and psychiatric and cognitive symptoms, they said.
“In addition, salpingectomy alone has a role in significantly reducing ovarian cancer incidence without compromising ovarian function because the fallopian tube has been found to be at the origin of many ovarian cancer cases,” they noted. In the current study, “the crude ovarian cancer risk was lower with BSO” across all age groups, the editorialists said.
The choice of whether to include BSO at the time of benign hysterectomy is complicated, with many factors to consider, the editorialists wrote, and the current study supports the need for informed, shared decision-making between clinicians and patients.
The study was supported by the Danish Cancer Society’s Scientific Committee and the Mermaid Project. The researchers had no financial conflicts to disclose. The editorial authors had no financial conflicts to disclose.
