Decision Support for Chemoprevention

4 november 2026 uppdaterad av: Rita Kukafka, Columbia University

Integrating Breast Cancer and Cardiovascular Disease Risk to Explore Decision-Making for Chemoprevention Among Women at High Risk for Breast Cancer

The purpose of this study is to find out whether electronic tools that provide information and reminders to people at high risk for breast cancer and their healthcare providers can increase the use of medications, such as tamoxifen, that may help lower the risk of developing breast cancer. The study will also look at how these tools can be successfully used as part of routine medical care.

Detaljerad beskrivning

This randomized controlled trial will evaluate whether the web-based RealRisks decision aid, combined with standard educational materials, increases breast cancer chemoprevention uptake among women at high risk for breast cancer compared with standard educational materials alone. The intervention incorporates individualized breast cancer and cardiovascular disease risk information to support informed decision-making regarding chemoprevention. The primary endpoint is chemoprevention uptake at 12 months. Secondary outcomes include medication beliefs, breast cancer risk perceptions, informed choice, and decision conflict.

Åtgärdsbeskrivning
Tidsram
Chemoprevention Uptake
Tidsram: 12 months after randomization

The primary outcome is to compare the uptake of breast cancer chemoprevention with selective estrogen receptor modulators (SERMs) or aromatase inhibitors (AIs) at 12 months among women at high-risk for breast cancer assigned to standard educational materials alone or combined with the web-based decision aid, RealRisks. Assessed by EHR log and self-report

Åtgärdsbeskrivning
Tidsram
Beliefs about medication
Tidsram: Baseline, 6 months, 12 months

Beliefs in Medication Questionnaire (BMQ)adapted for use in chemoprevention decision-making. The BMQ includes the Necessity scale (10 items that assess how patients perceive their personal need for chemoprevention for reducing BC risk, maintaining their health, and preventing illness), the Concerns scale (10 items measuring concerns about potential adverse effects of chemoprevention). Participants rate the extent to which they agree with each item on a scale (scored 1- 5). The total score for each scale is computed by adding the scores for each scale item together and dividing by the number of items.

Baseline, 6 months, 12 months
Perceived Breast Cancer Risk
Tidsram: Baseline, 6 months, and 12 months

3 items of absolute estimate, comparative risk assessed on a 3-point Likert scale, and numeric 10-year risk of breast cancer on a scale of 0 to 100%

Baseline, 6 months, and 12 months
Perceived Cardiovascular Disease Risk
Tidsram: Baseline, 6-months and 12-months

3 items of absolute estimate, comparative risk assessed on a 3-point Likert scale, and numeric 10-year risk of cardiovascular disease on a scale of 0 to 100%.

Baseline, 6-months and 12-months
Accuracy of Perceived Breast Cancer Risk
Tidsram: Baseline, 6 months, and 12 months

Difference between perceived numeric risk estimate and actual 10-year risk of breast cancer risk according to the BCSC risk calculator; Categorized as accurate if the difference between subjective and objective risk estimates are ≤5% in either direction, underestimate if >5% below objective risk, and overestimate if >5% above objective risk

Baseline, 6 months, and 12 months
Accuracy of Perceived Cardiovascular Disease Risk
Tidsram: Baseline, 6-month, and 12-month

Difference between perceived numeric risk estimate and actual 10-year risk of Cardiovascular Disease Risk according to the 2013 ACA/AHA ASCVD risk calculator; Categorized as accurate if the difference between subjective and objective risk estimates are ≤5% in either direction, underestimate if >5% below objective risk, and overestimate if >5% above objective risk

Baseline, 6-month, and 12-month
Informed Choice
Tidsram: Baseline, 6 months, and 12 months

This measure combines the chemoprevention knowledge scale, an attitudes scale, and chemoprevention decision. Informed choice defined as 1) those who have an adequate knowledge score, a positive attitude towards chemoprevention, and decide to take chemoprevention; 2) those who have an adequate knowledge score, a negative attitude towards chemoprevention, and decide not to take chemoprevention.

Baseline, 6 months, and 12 months
Decision Conflict
Tidsram: Baseline, 6 months, and 12 months

Score on the 10-item Decision Conflict Scale assessing uncertainty and conflict related to decisions about chemoprevention uptake. Items are rated using three response categories: Yes (0), Unsure (2), and No (4). Scores are summed, divided by 10, and multiplied by 25. Final scores range from 0 to 100, with higher scores indicating greater conflict and lower scores indicating less conflict.

Baseline, 6 months, and 12 months
Intention or decision about chemoprevention uptake
Tidsram: Baseline, 6 months, and 12 months

Behavioral intentions to take chemoprevention measured using 'Given what you know right now, how likely do you think you are to take a breast cancer prevention drug in the next year?' (1 = 'not at all likely,' to 5 = 'extremely likely').

Baseline, 6 months, and 12 months
Factors influencing intention about chemoprevention
Tidsram: Baseline, 6 months, and 12 months

Survey item to rank the main factors influencing a patient's decision about chemoprevention: 1) Personalized risk information; 2) polypharmacy for CVD or other comorbidities; 3) Provider recommendation; 4) RealRisks DA; 5) Other:____
