Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
EILEEN was a non-interventional/observational, retrospective, multi-center, real life cohort study conducted in 14 private and academic oncology clinics in Turkey. Group I cohort of the study was based on secondary use of data of postmenopausal hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) metastatic breast cancer (MBC) patients treated with ribociclib in combination with letrozole (LET) or fulvestrant (FUL) after June 2020. Group II cohort of the study was a parallel, comprehensive chart review for detecting all postmenopausal HR+, HER2- MBC patients who were eligible for cyclin-dependent kinase inhibitors (CDKis) but received chemotherapy. The study used secondary data which was retrieved from electronic or paper medical records or clinical databases available at the sites. Regular follow up with close monitorization was used for the effective management of patients with breast cancer. Data sources included information about diagnosis, treatment and monitorization of patients at an individual level. The study used medical patient records at hospitals e.g. hospital discharge files, primary clinical records and electronic medical records.
