A Cochrane review found that decision aids increased patients’ knowledge, helped patients clarify their values, and may improve value-concordant decisions.55 Two papers describing the use of decision aids for women with BRCA mutations56,57 documented decreased decisional conflict and increased satisfaction.

CASE

Ms. T underwent the recommended mammogram and MRI screening for breast ­cancer, as well as testing with serum CA-125 and ultrasound examinations for ovarian cancer. Her initial mammogram and MRI revealed early stage, triple-negative right breast cancer. She chose to undergo bilateral mastectomy and reconstruction. She has now completed treatment and continues to work closely with her oncology team for appropriate breast ­follow-up.

Two papers describing the use of decision aids for women with BRCA mutations documented decreased decisional conflict and increased satisfaction.

One year after her initial diagnosis, at the age of 35, she returned to discuss fertility. She was recently married, and she and her husband wanted to start having children. She was concerned about a safe timeline for her to pursue pregnancy, saying she felt “like a ticking time-bomb” given her prior cancer and carrier status. She wanted to discuss the risks and benefits of pregnancy and when she should consider prophylactic oophorectomy. She had a few options. She could have a baby and then undergo an RRSO, or she could talk to her gynecologist about having a salpingectomy to reduce her risk now and use assisted reproductive technology to get pregnant. She could also freeze eggs or embryos, have an RRSO, and then use a surrogate to get pregnant. We informed her that pregnancy would not affect her risk of ovarian cancer and discussed the options for pre-implantation genetic testing to assure that her children would not carry the genetic mutation.58

We provided Ms. T and her husband with a decision aid to help them navigate the decision. They are currently evaluating the options and said they would let us know when they made a decision.
