The standard of care for HER2-positive and hormone receptor-positive breast cancer patients who receive neoadjuvant chemotherapy (NACT) combined with trastuzumab, with or without pertuzumab, is to continue with adjuvant T-DM1 in cases of an incomplete response according to KATHERINE trial results. However, the optimal management for patients with residual disease with loss of HER2 expression is not widely studied. Loss of HER2 expression after NACT with anti HER2 is a rarer event with questionable value both as a predictive prognostic marker.

Endothelial Colony-Forming Cells (ECFCs) are recognized as key vasculogenic progenitors in humans and serve as valuable liquid biopsies for diagnosing and studying vascular disorders. In a groundbreaking study, Anceschi et al. present a novel, integrative strategy that combines ECFCs loaded with gold nanorods (AuNRs) to enhance tumor radiosensitization through localized hyperthermia.

Purpose: Limited data is available assessing sequencing of antibody drug conjugates (ADCs) in patients with hormone receptor-positive (HR +), human epidermal growth factor 2 (HER2)-negative, HER2-low, and triple-negative metastatic breast cancer (MBC), including patients with brain metastases (BrM) or leptomeningeal disease (LMD). This study assesses the efficacy and safety of sequential sacituzumab govitecan (SG) and trastuzumab deruxtecan (T-DXd) in MBC and impact on chemotherapy (CTX).
Methods: This is a single-center, retrospective, cohort study in adult patients with HR + , HER2-negative, or low MBC who received T-DXd and/or SG.
