Identifying patients who will respond to specific breast cancer treatments using a biomarker.

Tyrosine phosphorylation of p27Kip1 as a biomarker to identify Cdk4/6 inhibitor response

NIH-funded research Suny Downstate Medical Center · NIH-10852924

This study is looking to find a way to tell which women with metastatic breast cancer will benefit from a specific type of treatment called CDK4/6 inhibitors, so they can get the most effective care and avoid treatments that might not work for them.

What this research studies

This research focuses on developing a biomarker that can identify which patients with metastatic breast cancer will respond to CDK4/6 inhibitors, a class of drugs that has shown promise in treatment. By analyzing the tyrosine phosphorylation of p27Kip1, the study aims to pinpoint patients who are likely to benefit from these therapies, thereby avoiding ineffective treatments and reducing the need for chemotherapy. The goal is to enhance patient outcomes by ensuring that the right patients receive the right drugs at the right time, potentially expanding the use of these therapies to other cancer types as well.

Who could benefit from this research

Good fit: Ideal candidates for this research are patients diagnosed with metastatic hormone receptor-positive breast cancer who are considering treatment with CDK4/6 inhibitors.

Not a fit: Patients with early-stage breast cancer or those whose cancer is not hormone receptor-positive may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to more personalized and effective treatment options for patients with metastatic breast cancer.

How similar studies have performed: Other research has shown promise in developing biomarkers for cancer treatment responsiveness, indicating that this approach has potential for success.
