Summary

This study tested two different chemotherapy regimens given before surgery to shrink tumors in people with stage II or III breast cancer. One group received a standard three-drug combo (TAC), while the other received two different combos in sequence (ACAC), with some also getting trastuzumab if their cancer was HER2-positive. The goal was to see which approach led to no cancer remaining in the breast or lymph nodes at surgery. The trial enrolled 121 participants and is now complete but not actively recruiting.
