In spite of this, the activity of CDK4/6 inhibitors in patients with metastatic breast cancer who have progressed despite receiving multiple lines of treatment is not well understood.Aims: To report the activity and safety of a CDK4/6 inhibitor (palbociclib) in patients in whom at least three lines of treatment for ER+ metastatic breast cancer had failed.Study Design: Multicenter retrospective observational cohort study.Methods:Inthisretrospectiveobservationalcohortstudy,weincluded 43 patients who received palbociclib after at least three lines of systemic treatment for ER+/HER2− metastatic breast cancer.Results: The median progression-free survival in our population was 7 months (25th-75th percentile, 4-10), and the median overall survival was 11 months (25th-75th percentile, 6-19).

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Background: The synthesis of CDK4/6 inhibitors with endocrine treatment in two series of treatment has been widely accepted as the standard for patients with estrogen receptor-positive metastatic breast cancer.
📊
Key Findings & Data:In spite of this, the activity of CDK4/6 inhibitors in patients with metastatic breast cancer who have progressed despite receiving multiple lines of treatment is not well understood.Aims: To report the activity and safety of a CDK4/6 inhibitor (palbociclib) in patients in whom at least three lines of treatment for ER+ metastatic breast cancer had failed.Study Design: Multicenter retrospective observational cohort study.Methods:Inthisretrospectiveobservationalcohortstudy,weincluded 43 patients who received palbociclib after at least three lines of systemic treatment for ER+/HER2− metastatic breast cancer.Results: The median progression-free survival in our population was 7 months (25th-75th percentile, 4-10), and the median overall survival was 11 months (25th-75th percentile, 6-19).
💡
Conclusion & Impact:Although there were some adverse events, palbociclib was generally well tolerated, so dose reduction was needed for only six patients (14%).Conclusion: The efficacy of palbociclib among heavily treated hormonereceptor-positive/HER2−patientswithadvancedbreastcancer was acceptable in terms of clinical benefit, and it was generally well tolerated among this population.

Abstract

Background: The synthesis of CDK4/6 inhibitors with endocrine treatment in two series of treatment has been widely accepted as the standard for patients with estrogen receptor-positive metastatic breast cancer. In spite of this, the activity of CDK4/6 inhibitors in patients with metastatic breast cancer who have progressed despite receiving multiple lines of treatment is not well understood.Aims: To report the activity and safety of a CDK4/6 inhibitor (palbociclib) in patients in whom at least three lines of treatment for ER+ metastatic breast cancer had failed.Study Design: Multicenter retrospective observational cohort study.Methods:Inthisretrospectiveobservationalcohortstudy,weincluded 43 patients who received palbociclib after at least three lines of systemic treatment for ER+/HER2− metastatic breast cancer.Results: The median progression-free survival in our population was 7 months (25th-75th percentile, 4-10), and the median overall survival was 11 months (25th-75th percentile, 6-19). Although there were some adverse events, palbociclib was generally well tolerated, so dose reduction was needed for only six patients (14%).Conclusion: The efficacy of palbociclib among heavily treated hormonereceptor-positive/HER2−patientswithadvancedbreastcancer was acceptable in terms of clinical benefit, and it was generally well tolerated among this population.
