Paolo Tarantino discusses how advancements in HER2-positive early-stage breast cancer treatment, including anthracycline-based regimens, non-anthracycline alternatives, and biomarker integration, are leading to more personalized medicine. Trastuzumab, pertuzumab, TKIs, and trastuzumab emtansine are central to these advancements, aiming to optimize treatment and minimize adverse effects. The HER2DX assay and imaging biomarkers like PET scans and MRI are refining treatment decisions, while neoadjuvant treatment strategies allow for tailored post-treatment care.
