Abstract | BACKGROUND: PATIENTS AND METHODS: From September 2011 to September 2013, 4 cycles of preoperative chemotherapy with TRI-ABC followed by 4 cycles of FEC were administered in patients with resectable breast cancer. In patients with HER2-positive breast cancer, tri-weekly Trastuzumab was administered with TRI-ABC. The primary end point was the pathological complete response (pCR) rate in the breasts and lymph nodes. RESULTS: The treatment outcomes and safety were evaluated in 54 patients who received at least 1 dose of chemotherapy. All patients underwent radical surgery, and the overall pCR rate of 37% (20 of 54) was achieved. The pCR rates according to each subtype were 8% (2 of 24) in hormone receptor (HR)-positive HER2-negative breast cancer, 56% (5 of 9) in HR-positive HER2-positive breast cancer, 63% (5 of 8) in HR-negative HER2-positive breast cancer, and 62% (8 of 13) in triple-negative breast cancer. Multivariate analysis revealed that HR negativity and HER2 positivity were predictive factors of pCR. Clinical response was observed in 49 patients (91%). The safety profile was acceptable. CONCLUSION: Preoperative chemotherapy with TRI-ABC followed by FEC showed high efficacy and excellent safety. Further clinical studies should be conducted to compare the efficacy of TRI-ABC followed by FEC with conventional taxane- anthracycline regimens.
