Predicting outcomes of CDK4/6 inhibitors plus hormone therapy for advanced breast cancer
This study looks at how well a type of targeted therapy (called CDK4/6 inhibitors) combined with hormone therapy works as the first treatment for advanced breast cancer that is hormone receptor-positive and HER2-negative. Researchers want to find patterns that could help predict which patients benefit most.
AvianoAges 18 years+ - NCT06813456Recruiting
Improving HER2 detection in breast cancer with new testing method
This trial studies a more precise way to measure HER2 levels in breast cancer tissue. It may help identify patients whose cancer is HER2-low or HER2-zero, so they can get more targeted treatment.
