Blood markers may reveal breast Cancer's next move
NCT ID NCT07297134
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing whether certain substances in the blood can help predict where breast cancer might spread. Researchers will measure levels of a protein called PTEN and specific microRNAs in blood samples from 160 women: 80 with metastatic breast cancer, 40 with early-stage breast cancer, and 40 healthy volunteers. The goal is to develop a non-invasive blood test that could guide doctors in monitoring and treating breast cancer more effectively.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to a simple blood test that helps doctors predict where breast cancer might spread, enabling more personalized monitoring and treatment planning.
- What could go wrong
- This is an early observational study, not a treatment trial. The findings may not translate into a reliable clinical test, and the biomarkers identified may not be specific or sensitive enough for routine use.

Who is studied
Three groups were included in this study: women with metastatic breast cancer, women with early or locally advanced nonmetastatic breast cancer, and age-matched healthy female controls. Participants in the metastatic group have radiologically or clinically confirmed distant organ involvement. The nonmetastatic group includes patients with histopathologically confirmed breast cancer without any evidence of distant metastasis. Healthy controls consist of women without known breast disease, malignancy, or systemic illness. All participants are aged 18 years or older and able to provide informed consent. Recruitment will occur through oncology clinics, breast surgery units, and outpatient services.
