NCT ID NCT00911911

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This completed study looked at blood and tumor samples from 66 women with breast cancer who were about to receive chemotherapy before surgery. Researchers searched for unique protein patterns that might show whether the tumor would shrink with treatment. The goal was to find a way to personalize chemotherapy and avoid ineffective treatments.

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 help doctors predict which breast cancer patients will respond well to chemotherapy before treatment starts.

What could go wrong

This is an observational study that only looks for protein patterns—it does not test a new treatment. The results may not lead to a practical test or change how patients are treated.
