Table 1.
Intervention | Advantages | Disadvantages |
---|---|---|
Surveillance for breast cancer (monthly breast self-exam, semiannual clinical breast exam, annual mammogram, annual breast MRI) | Relatively noninvasive Breast MRI increases the likelihood of early-stage breast cancer detection although it is not clear that it improves survival |
Breast MRI has low specificity and may lead to more diagnostic testing |
Surveillance for ovarian cancer (semiannual pelvic exam, serum CA-125 and pelvic ultrasound) | Noninvasive | No evidence for efficacy of early-stage ovarian cancer detection No effect on ovarian cancer mortality Serum CA-125 has low specificity May be associated with emotional distress |
RRM | Breast cancer risk reduction by 90% | Body-image issues Surgical risks: seromas, wound infection, skin flap necrosis, pain, lymphedema, shoulder dysfunction |
RRSO | Ovarian cancer risk reduction by 72% Breast cancer risk reduction by 50% if completed before onset of menopause Decreases overall mortality by 60%, breast cancer mortality by 56% and ovarian cancer mortality by 79% Laparoscopic procedure |
Increases risk of symptoms and health consequences of premature menopause (if performed before age 35): vasomotor symptoms, sexual dysfunction, cardiovascular disease, stroke, cognitive decline, depression, anxiety, osteoporosis, mortality Surgical risks: urinary tract injury, wound infection, pelvic abscess |
RRSO+hysterectomy | As for benefits of RRSO (above) Allows for estrogen-only HT (alleviating need for progestogen) use Eliminates small risk of uterine cancer if tamoxifen is used |
Surgical risks: similar to RRSO but greater risk plus vaginal cuff dehiscence, transfusion, rehospitalization, reoperation |
Salpingectomy/fimbriectomy | May decrease risk of ovarian cancer May be considered as a bridge to RRSO in premenopausal women |
No clear evidence of ovarian cancer risk reduction Unknown effect on breast cancer risk |
Tamoxifen | Limited evidence from small studies for breast cancer risk reduction in BRCA carriers | Slightly increases risk of uterine cancer Increases risks of stroke, cataracts, thromboembolic events Side effects (vasomotor symptoms, vaginal dryness and discharge, fatigue, arthralgias) |
OC | Ovarian cancer risk reduction by 50% | Concern for possible increased risk of breast cancer with prolonged use (>5 years) Increased risk of venous thromboembolic events Side effects ( nausea, bloating, breast tenderness, breakthrough bleeding) |
HT after RRSO in premenopausal women | Alleviates symptoms and reduces health consequences of early menopause (cardiac disease, osteoporosis, Parkinsonism, dementia) | Side effects and risks (venous thromboembolism, stroke, breast cancer with E+P HT, cholelithiasis) |
E, estrogen; HT, hormonal therapy; MRI, magnetic resonance imaging; OC, oral contraceptives; P, progestogen; RRM, risk-reducing mastectomy; RRSO, risk-reducing salpingo-oophorectomy.
