[Does ovarian cancer start in the fallopian tubes? Possible implications for preventive adnexal removal]

BACKGROUND: Recent insights in high-grade serous ovarian cancer development are pointing to the fallopian tubes as likely place of origin and not the ovaries themselves. This may have consequences for patients with increased risk of ovarian cancer. Adnexal removal is currently recommended for this patient group at an age of 35-45, which leads to premature menopause. CASE DESCRIPTION: In a 55-year-old woman with a BRCA1 germ line mutation, a high-grade serous carcinoma was unexpectedly diagnosed in both fallopian tubes during preventive adnexal removal. Her ovaries did not have any abnormalities. CONCLUSION: This case illustrates a fallopian tube origin for high-grade serous ovarian cancer development in a carrier of a BRCA1 germ line mutation. In the future, salpingectomy could play a role in ovarian cancer prevention. However, research is needed first to demonstrate the safety of this strategy. Salpingectomy in women with a BRCA germ line mutation should therefore only be performed in the context of research for the time being
