A Real-life Study to Learn About the Use and Effects of the CDK4/6 Inhibitors in Canadian Patients With Breast Cancer.
Treatment Patterns And Clinical Outcomes Among Patients Receiving CDK4/6 Inhibitors Combinations For HR+/HER2- Advanced/Metastatic Breast Cancer In A Canadian Real World Setting
CDK4/6 inhibitors are approved medicines indicated for the treatment of a kind of advanced/metastatic breast cancer, called hormone receptors positive (HR+)/ Human epidermal growth factor receptor 2 negative (HER2-) disease. They are given orally in combination with hormonal therapies.
The purpose of this study is to better understand how the CDK4/6 inhibitors combinations are used in real-life conditions and their clinical impact for the treatment of Canadian patients affected by (HR+)/ (HER2-) advanced breast cancer (ABC) or metastatic breast cancer (MBC).
Female patients aged 18 years old or more presenting the following conditions will be selected for the study:
- HR+/HER2- breast cancer diagnosis with confirmed metastatic or advanced disease
- Diagnosis of ABC/MBC between 01 January 2016 and 01 July 2021
- Treatment with CDK4/6 inhibitor
Information will be collected from one single Canadian institution, on each selected real-life patient treated with CDK4/6 inhibitors.
