A Feasibility Trial of a Web Based App Intervention in Hormone Positive Breast Cancer Patients to Improve Adherence to Endocrine Therapy

This clinical trial looks at the use of an internet-based application (app) intervention in improving adherence to endocrine therapy (ET) among patients with early stage hormone receptor-positive HER2-negative breast cancer. ET can significantly reduce the return of the cancer in patients who are compliant with their treatment regimen. Despite this, adherence to ET is poor due to side effects, lack of social support and timely access to clinicians, and poor patient understanding of the necessity and effectiveness of the therapy. An internet-based app may help patients improve their adherence to ET by providing reminders, side effect mitigation strategies available in the educational videos and from contacting providers/ nurse on the research team directly via the app.
