Evaluating Minimal Residual Disease (MRD) Through Longitudinal Circulating Tumor DNA (ctDNA) Profiling in Breast Malignancies

Sponsored by Tempus AI

About this study

For patients with breast cancer, it's important to find any remaining cancer cells after they've had their main treatment. Even a few cells, called minimal residual disease (MRD), can lead to the cancer coming back later. A way to find these cells is by looking for tiny bits of cancer DNA that are shed into the blood. This is called circulating tumor DNA (ctDNA). A simple blood test, often called a liquid biopsy, can detect this ctDNA. This research aims to see if finding this cancer DNA in the blood can help predict if a patient's cancer will return. It also may help find out if the treatment is working. Ultimately, the results of this research may help doctors better manage breast cancer and develop new and improved tests and treatments.

Only the research team can confirm whether you qualify. The intake questionnaire is the best way to find out.

Completing a questionnaire on Clinably does not enroll you in a clinical trial or confirm your eligibility. Only the research team can determine whether you qualify to participate. These results are based on the information you provide and are intended to help you start a conversation with the research team.
