Background: Neoadjuvant systemic therapy is the preferred treatment approach for stage II-III HER2-positive breast cancer (BC). Real-life data comparing regimens with or without anthracyclines combined with two HER2 drugs is lacking. We compared the efficacy and toxicity of two commonly used regimens.

Background: The HER2DX assay predicts long-term prognosis and pathologic complete response (pCR) in patients with early-stage human epidermal growth factor receptor 2 (HER2)-positive breast cancer receiving neoadjuvant systemic therapy but has not been evaluated in inflammatory breast cancer (IBC).
Patients And Methods: HER2DX was analyzed in baseline biopsy tissues from 23 patients with stage III HER2-positive IBC on a phase II trial (NCT01796197) treated with neoadjuvant trastuzumab, pertuzumab, and paclitaxel (THP). To assess the assay's predictive accuracy for pCR in IBC, clinical-pathological features and outcomes from this IBC cohort were compared with 156 patients with stage III HER2-positive non-IBC from four different cohorts.

The role of anthracyclines in the treatment of early breast cancer (EBC) is increasingly being challenged, especially in de-escalation strategies. However, owing to their immunogenic effects, anthracyclines are promising combination partners with immunotherapies. In the randomized phase 2 trial ABCSG-52 (EudraCT no.

The efficacy of neoadjuvant therapy varies significantly with hormone receptor (HR) status for patients with human epidermal growth factor receptor 2 (HER2) positive breast cancer (BC). Despite extensive research on HER2 + BC, the optimal neoadjuvant strategy for HR+/HER2 + BC remains inconclusive. This study aimed to identify the optimal neoadjuvant regimen for HR+/HER2 + BC treatment.

Importance: Current chemotherapy regimens for patients with ERBB2 (formerly HER2)-positive breast cancer are associated with considerable morbidity. These patients may benefit from more effective and less toxic therapies.
Objective: To evaluate the safety, immunogenicity, and preliminary efficacy of intratumoral (IT) delivery of conventional type 1 dendritic cells (cDC1) in combination with ERBB2-targeted therapies.
