||Empower Study: Promoting Bc Screening in Women Who Survived Childhood Cancer
By age 50, almost one in three women, treated with chest radiation for a childhood cancer, will be
diagnosed with breast cancer. Early detection of breast cancer is strongly associated with survival, and
surveillance with annual breast MRI and mammography is recommended, starting at age 25. Unfortunately, the
vast majority of these women are not adherent to the recommended surveillance. Magnifying this problem,
most childhood cancer survivors are no longer followed at a cancer center, are unaware of their risks, and are
being followed by primary care providers (PCPs) who are not informed about the recommended follow-up care.
Based upon our prior findings in EMPOWER-I, we now propose EMPOWER-II, a 3-arm randomized
controlled trial that extends the core component of the EMPOWER-I intervention (mailed educational materials)
to evaluate the utility of patient activation with and without added PCP activation to increase breast cancer
surveillance. We propose to randomize 291 women, who are at least 25 years of age, with a history of chest
radiation for a childhood cancer, without a history of breast cancer, and without both a breast MRI and
mammogram in the previous two years.
The primary outcome is obtaining a breast MRI and mammogram during the 12-month study period.
We will determine the comparative effectiveness of (1) a smartphone-based patient activation intervention and
(2) patient activation plus PCP activation, compared to control. Secondary aims include exploring moderating
and mediating factors that predict surveillance completion, timing of the obtained surveillance, and estimating
the intervention replication costs and costs resulting from the intervention.
The proposed EMPOWER-II study brings together a research team with the necessary expertise and
experience in both survivorship research, smart-phone delivered interventions, and the unique resource of the
31-insitution Childhood Cancer Survivors Study (CCSS). Notably, the CCSS represents the single largest
cohort of women in the target population and the infrastructure to conduct the proposed study. Results from
this intervention will have important implications for all high-risk women treated with chest radiation at a young
