About this study
Official title: Registry Study of Patients With Advanced Breast Cancer Treated With Cyclin-dependent Kinase 4/6 (CDK4/6) Inhibitors Combined With Endocrine Therapy: the Experience of the Hellenic Cooperative Oncology Group
The present study will assess real-world clinical outcomes and adverse events from treatment with endocrine therapy combined with CDKi in patients with HR-positive, HER2-negative advanced breast cancer.
Read the detailed description
Patients This will be a retrospective analysis of patients with histologically confirmed HR-positive, HER2-negative advanced (recurrent or metastatic) breast cancer. The investigators will use data from patients treated at Hellenic Cooperative Oncology Group (HeCOG)-affiliated departments of oncology. Eligible patients will be of 18 years or older, women of any menopausal status with HR-positive/HER2-negative advanced breast cancer who have received treatment with CDKi in combination with endocrine therapy for their advanced breast cancer. Treatment combinations of CDKi with any endocrine therapy will be accepted. Patients will be included in the analysis if they heve received at least two months of treatment with a CDKi. Patient clinical data will be obtained from their medical records. Toxicity data will be recorded from the clinicians' documentations during scheduled patient clinical visits.
Statistical analysis The primary endpoint of the study will be progression-free survival (PFS), defined as the time from treatment initiation to either the first documented disease progression or death from any cause. Secondary endpoint will be overall survival (OS), defined as the time from treatment initiation to patient death or last contact. Patients alive will be censored at the date of last contact. Adverse events will be graded based on Common Terminology Criteria for Adverse Events (CTCAE, version 4.0). Survival curves will be estimated using the Kaplan-Meier method and compared across groups with the log-rank test. The associations between the clinicopathological factors to be examined and the mortality rate will be evaluated with hazard ratios estimated with Cox proportional hazards model. The statistical analyses will be completed using the SAS software (SAS for Windows, version 9.3, SAS Institute Inc., Cary, NC).

What is being measured
The primary outcome is the main question the study is designed to answer.
Toxicity rates
Rates of adverse events from the combination of CDKi and endocrine therapy

Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04133207, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
