Abstrakt: This study aimed to investigate the impact of HER2-low on the risk of recurrence in individuals with inflammatory breast cancer (IBC). 60 females with HER2-low and HER2-positive IBC underwent surgery between July 2020 and July 2022. Patients were divided into three groups of 20 patients: (1) HRplus/HER2-, (2) HRplus/HERplus, and (3) HR-/HER2plus. All patients underwent chemotherapy in adjuvant mode, following this scheme: TCH=docetaxel and carboplatin plus Herceptin (HER2 target - 4 mg/kg as the loading dose and 6 mg/kg as subsequent doses throughout every 21 days, entire 52 weeks of Herceptin therapy). HRplus/HERplus group had an OS of 76.9% compared with 77.0% in the group with the HRplus/HER2plus subtype and 74.4% in the HR-/HER2plus group. Moreover, recurrence-free survival was 19.1% for the HRplus/HER2- group, 21.3% for the HRplus/HERplus group, and 11.7% for the HR-/HER2plus group. In our study, patients with HER2-low IBC could acquire a perfect response with preliminary systemic therapy, without disease progression or with stable disease on target alone. Further examination is important to decide on the most effective treatment regimens, in addition to mixing chemotherapy with HER2-low-focused on agents.
