Compliance to a Hormone Therapy Regimen in Breast Cancer
RATIONALE: Understanding how well patients comply with their treatment regimen may help doctors plan the best treatment and ongoing care.
PURPOSE: This clinical trial is studying whether patients comply with their hormone therapy regimen in women with estrogen receptor-positive stage I, stage II, or stage IIIA breast cancer.
|Breast Cancer||Behavioral: compliance monitoring Other: medical chart review Other: questionnaire administration|
|Study Design:||Observational Model: Case-Only

|Official Title:||Adherence to Endocrine Therapy in Women With Breast Cancer in Clinical Practice Settings|
- Adherence to endocrine therapy [ Time Frame: at 5 yrs ]
- Effects of categorical predictors of compliance [ Time Frame: at 5 yrs ]
- Comparison of the means of each continuous predictor between compliers and non-compliers [ Time Frame: at 5 yrs ]
- Effects of continuous and categorical variables on compliance, controlling for other factors including age at diagnosis, race, education, and type of surgery [ Time Frame: 5 yrs ]
- Time to discontinuation of tamoxifen as a time-to-event outcome [ Time Frame: 5 yrs ]
- Univariate and multivariate associations of covariates with risk of noncompliance [ Time Frame: 5 yrs ]
|Study Start Date:||December 2007|
|Study Completion Date:||December 2015|
|Primary Completion Date:||September 2009 (Final data collection date for primary outcome measure)|
Behavioral: compliance monitoring
- To examine the relationship between adherence to endocrine therapy and variables from the Health Belief Model (i.e., perceived risk, barriers to and benefits of adherence, and cues to action such as physician recommendation) as well as measures of patient's perceptions of patient- and family-centered care in women with estrogen receptor-positive stage I-IIIA breast cancer.
OUTLINE: Patients complete a 15 minute questionnaire on-line or by mail comprising questions of demographic and medical variables (i.e., age, race/ethnicity, marital and educational status, and medication side effects) as well as health beliefs and selected aspects of patient- and family-centered care. Data collected from the questionnaire will be stored in an Excel database.
Patient's medical records are reviewed for information about the time since diagnosis, tumor characteristics, treatment, and comorbidity.
