Purpose: To increase the appropriate breast cancer risk quantification, utilization of chemoprevention, and genetic counseling among Women Veterans at high risk for breast
cancer in accordance with national guidelines.
Background/Rationale: There are over 2 million women who constitute the fastest growing segment of eligible veterans within the VHA. The number of women diagnosed with breast cancer has more than tripled from 1995 to 2012. Chemoprevention reduces the risk of breast cancer by 50-62% in high risk patients. An estimated 10 million women in the U.S. may be eligible, but fewer than 5% of high risk women are offered chemoprevention.
Methods: This is an ongoing feasibility pilot study being conducted at 2 VAMCs (“VAMC 1” and “VAMC 2”) with plans for expansion to 7 more VAMCs. Participants were enrolled at the time of their regular visit to Women’s Health Clinics. Eligibility criteria includes: women age ≥ 35 with no history of breast cancer. After completing a 20 multiple choice questionnaire, 5-year and lifetime risk of invasive breast cancer is calculated using the Gail risk tool (BCRAT). A woman is considered high risk and eligible for chemoprevention if her 5-year risk is ≥ 1.67% or her lifetime risk is ≥ 20%. Eligibility for genetic counseling is based on the Breast Cancer Referral Screening Tool (B-RST), which includes a personal or family history of breast or ovarian cancer and Jewish ancestry.
Results: 72 females (42 at “VAMC 1” and 30 at “VAMC 2”) were enrolled and completed the questionnaire. Of these patients, 17/42 (40%) and 6/30 (20%) had Gail score of > 1.66 and were considered high risk for breast cancer. All 23 females at both facilities had Oncology clinic consultations for chemoprevention. Only 1 female at each center accepted chemoprevention with tamoxifen (“VAMC 1”) and anastrazole (“VAMC 2”). Six patients had telehealth genetic counseling consults.
Implications/Future Directions: Increasing awareness of breast cancer risk status and utilization of prevention options is a critical element in our program to increase screening and provide chemoprevention according to national guidelines in the VHA. Future directions include tool development and national spread of screening efforts.
