Blood test may predict which triple-negative breast cancers will return
NCT ID NCT06418126
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether measuring certain inflammatory proteins (cytokines) in the blood during radiotherapy can help predict which triple-negative breast cancer patients are likely to have their cancer come back. Researchers will take blood samples from 15 women before and during radiotherapy and track their health for up to 5 years. The goal is to find a simple way to identify high-risk patients who might need extra treatment.
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 blood test that identifies which TNBC patients are at high risk of recurrence after radiotherapy.
- What could go wrong
- This is a very small, early-stage study with only 15 participants. It is observational and does not test a new treatment, so results may not lead to a usable test.
