Assessment of the Decision-making Impact of the Breast Cancer Index in Recommending Extended Adjuvant Endocrine Therapy for Patients With Early Stage ER-positive Breast Cancer

Not Applicable

Completed

• Conditions: Early Stage Estrogen Receptor (ER) Positive Breast Cancer; Breast Cancer

• Registration Number: NCT02057029
• Lead Sponsor: Yale University

Brief Summary

Investigators will examine the impact of the Breast Cancer Index (BCI) result on patients' anxiety / fear of recurrence and satisfaction with decisions regarding endocrine therapy.

Detailed Description

The investigators' objective is to assess patient decision-making, anxiety and patient satisfaction with recommendations made by an oncologist before and after the BCI test results are known. In addition, a chart review will be performed annually for five years to assess disease status and medications. Specifically, if extended endocrine therapy was recommended the chart review will record if participants are taking the medication and, if not, why the treatment was discontinued.

• Sex: Female
• Target Recruitment: 96

Inclusion Criteria

Each patient must meet all of the following criteria in order to be considered for enrollment:

• Histologically confirmed ER positive, stage I-III breast cancer who have been treated with curative intent and completed at least four years of adjuvant endocrine therapy.
• Life expectancy ≥ 5 years.
• Must be able to provide informed consent.
• Willing to consider continuation of endocrine therapy beyond 5 years.

Exclusion Criteria

• A patient must not be enrolled if any contraindication exists for extended adjuvant endocrine therapy as identified by the treating oncologist.

Study & Design

• Study Type: INTERVENTIONAL
• Study Design: SINGLE_GROUP

Primary Outcome Measures

Name	Time	Method
Patient Endocrine Therapy Questionnaires	4 weeks	These questionnaires are aimed at gathering the patient's perceived risk of recurrence, preference for continuing endocrine therapy after 5 years, concerns surrounding taking additional medication including concerns of cost, side effects, safety and benefit, as well as the level of comfort with the choice made both before and after the BCI test results are known.

Secondary Outcome Measures

Name	Time	Method
Decision Conflict Scale	4 weeks	The Decisional Conflict Scale (DCS) will be used to measure the uncertainty of the patient in making a health-related decision (in this case, making the decision to take or not to take extended endocrine therapy), the factors contributing to the uncertainty and the perceived effective decision making.
State-Trait Anxiety Inventory	4 weeks	Anxiety will be measured using the 20-item State-Trait Anxiety Index. This test differentiates between transient anxiety ('state anxiety') and more long-standing anxiety ('trait anxiety'). Participants will be asked to complete only the state anxiety (STAI-Y1) as trait anxiety is not expected to be modifiable based on the knowledge of the BCI results.
