Can a blood test predict breast cancer treatment response?
Part of Cancer, Skin clinical trials.
This study looks at whether a blood test (ctDNA) can help predict how well breast cancer responds to chemotherapy before surgery. It focuses on people with HER2-positive or triple-negative breast cancer that has not spread far.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are a woman aged 18 or older.
- You have stage II or III breast cancer that is HER2-positive or triple-negative.
- Your doctor plans to give you chemotherapy before surgery (neoadjuvant therapy).
- A tissue sample (biopsy) from your diagnosis and another from your surgery must be available for testing.
- You are willing to take part in the study.
- You have not been treated for breast cancer before (this is your first treatment).

This study is for people with early-stage triple-negative breast cancer (TNBC) that has not been treated yet. Researchers want to see if tracking tumor DNA in your blood can help guide treatment decisions. You would receive standard chemotherapy and surgery, plus give blood samples.
This study uses a simple blood test (liquid biopsy) along with imaging scans to look for early signs that triple-negative breast cancer may have returned in patients who still had cancer after chemo. It aims to catch a possible recurrence sooner, which could help guide earlier treatment.
This study looks at tiny particles in your blood and tumor to see if they can predict how well your chemotherapy will work for breast cancer. The goal is to help guide treatment based on your individual cancer.
This trial uses a special blood test to track cancer signals (called ctDNA) during and after treatment for early breast cancer. It aims to see whether monitoring these signals can help guide follow-up and treatment decisions.
This study is testing a way to use a simple blood test during chemotherapy to see how well the treatment is working in certain breast cancers. The goal is to make sure you get the best treatment for your tumor type.
This study tests a new blood test to see if it can find tiny bits of tumor DNA after chemotherapy. If you have a larger or higher-risk breast cancer and are getting chemotherapy before surgery, you may join. The test could help doctors know if your cancer is gone or if more treatment is needed.
