Evaluating blood and imaging tests to measure treatment response in metastatic breast cancer with bone involvement

Role of ctDNA change as a response measure in the EA1183 patient population and how ctDNA changes correlate with metabolic response by serial FDG PET/CT

NIH-funded research University of Washington · NIH-10910869

This study is looking at how tracking changes in tumor DNA and using special imaging can help us understand how well treatment is working for people with breast cancer that has spread to the bones, so we can better predict their health outcomes.

What this research studies

This research investigates how changes in circulating tumor DNA (ctDNA) and metabolic responses observed through FDG-PET/CT imaging can provide better measures of treatment response for patients with bone dominant and bone only metastatic breast cancer. By integrating these two approaches, the study aims to determine if they can predict important clinical outcomes such as progression-free survival and time to skeletal-related events. Patients will have their ctDNA collected and undergo imaging to assess their disease status over time, providing a non-invasive way to monitor their response to therapy.

Who could benefit from this research

Good fit: Ideal candidates for this research are patients diagnosed with bone dominant or bone only metastatic breast cancer who are participating in the EA1183 FEATURE trial.

Not a fit: Patients with non-bone metastatic breast cancer or those not participating in the EA1183 FEATURE trial may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to improved methods for assessing treatment effectiveness in patients with metastatic breast cancer, potentially leading to better personalized treatment plans.

How similar studies have performed: Previous research has shown promise in using ctDNA and imaging biomarkers for monitoring cancer treatment responses, suggesting that this approach could yield valuable insights.
