Abstract

A retrospective descriptive study with longitudinal follow-up aimed at evaluating the efficacy of neoadjuvant treatment with dose-dense AC-T chemotherapy in combination with anti-HER2 agents (trastuzumab, pertuzumab) in HER2-positive breast cancer patients at the Department of Oncology and Palliative care, Hanoi Medical University Hospital from January 2016 to September 2023. The results showed that: in 37 patients enrolled in the study, median age was 50.2 (range 33 - 74 years old), 24 (64.9%) were at stage II and 13 (35.1%) were at stage III. Median tumor size was 40mm, and the rate of patients who had hormone receptor (HR) positive diseases was 62.2%. Total pathological complete response (tpCR) was achieved in 54.1% of the evaluated patients. Patients with HR negative had a statistically significant higher response rate (p < 0.05), while there was no significant association between tpCR rates and age, tumor size, tumor grade, Ki-67 expression, and regimen. There was no patient who had progressive disease.
