Breast cancer study: does adding trastuzumab to Pre-Surgery chemo improve outcomes?
NCT ID NCT01750073
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase II trial studied 92 women with early-stage breast cancer to see how well chemotherapy (paclitaxel and cyclophosphamide) with or without trastuzumab works before surgery. The main goals were to check side effects and see if the tumor disappears completely by the time of surgery. The study included patients with different types of breast cancer, including HER2-positive and HER2-negative.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- paclitaxel, cyclophosphamide, and trastuzumab
- What this could lead to
- If successful, this could show that adding trastuzumab to chemotherapy before surgery helps shrink tumors more effectively in HER2-positive breast cancer patients.
- What could go wrong
- This is a small, completed phase II trial, so results are preliminary. The approach may not work for all breast cancer types, and chemotherapy carries risks like infection and heart damage.
