Biomarker study for metastatic breast cancer
Part of Cancer clinical trials.
This study looks at blood and tissue samples from people with advanced or metastatic breast cancer to find biological markers (biomarkers) that might predict how well treatments work. The goal is to help doctors choose the most effective therapy for each person.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 18 years or older.
- You must have breast cancer that is locally advanced (stage III) and can't be removed with surgery, or has spread to other parts of the body (stage IV).
- You must not have had any treatment for your metastatic breast cancer yet.
- You must be planning to start systemic treatment (chemotherapy, hormone therapy, or targeted therapy).
- You must be able to have a biopsy (a small tissue sample taken) from at least one area where the cancer has spread.

This study helps doctors use more individualized (precision) treatment choices for people with certain advanced cancers. You may be offered study care based on your cancer details, aiming to improve treatment decisions.
This study looks for new markers in the blood or tumor that could predict how well immunotherapies work for advanced digestive and gynecological cancers. It includes people getting immunotherapy, chemotherapy, or targeted therapy, and also those with certain liver or abdominal metastases that can be surgically removed after chemo.
This study collects blood and tumor samples to understand how well cancer immunotherapy works and what side effects may happen. It mainly helps researchers by checking “immune markers” before treatment starts, while you receive planned immune checkpoint therapy.
This study looks at immune and tumor “behavior” markers in people with metastatic melanoma after standard treatment. It may help researchers understand why treatment works for some people and not others by testing blood and skin tumor samples.
This study collects samples to find biomarkers related to bone metastases in common cancers. It might help doctors better understand why cancer spreads to bones.
This study tests how well and how safely different combinations of cancer drugs work for people with metastatic or inoperable locally advanced breast cancer. It may help by finding a better treatment option and collecting information to guide future care.
