BRCA Carriers Face High Ovarian Cancer Risk Even at Older Ages
A study in JAMA Surgery found that BRCA1 carriers who delay preventive surgery to age 50 still have a 23.9% lifetime risk of ovarian cancer. Residual risk declines with age but remains substantial, especially for BRCA1. The authors advise individualized counseling that weighs risk reduction against menopausal harms and quality of life.
The JAMA Surgery analysis calculated actuarial risks through age 80, finding BRCA1 carriers face a 56.8% lifetime ovarian cancer risk versus 25.4% for BRCA2 carriers. These figures surpass earlier estimates, prompting the authors to argue that healthy older carriers should not automatically dismiss preventive surgery.
Current guidelines from NCCN and SGO recommend bilateral salpingo-oophorectomy between ages 35-40 for BRCA1 and 40-45 for BRCA2. However, commentary authors note that interval salpingectomy with delayed oophorectomy may reduce tubo-ovarian cancer risk by up to 80% while preserving fertility, and two large trials are evaluating this approach.
This study could reshape how clinicians counsel older BRCA carriers, who may currently assume age diminishes the value of preventive surgery. Women weighing surgical menopause against cancer prevention may benefit from more precise risk estimates, potentially leading to better-informed decisions. The findings may also encourage broader discussion of fertility preservation and menopausal hormone therapy, affecting quality of life for thousands of at-risk women.
