BBIU T-DXd + Pertuzumab Redefines First-Line HER2+ Therapy: Quantitative Supremacy, Structural Risk

n the quiet space between diagnosis and decision, a woman with metastatic, unresectable HER2-positive breast cancer confronts three divergent paths. On one side, the long-familiar THP regimen — taxane, trastuzumab, and pertuzumab — the cornerstone of a decade’s treatment. In front of her, the new architecture of antibody–drug conjugates: trastuzumab deruxtecan (T-DXd) plus pertuzumab, a design where cytotoxic precision replaces the blunt force of chemotherapy. And to the third path, the unblinded promise of T-DXd monotherapy — still in shadow, awaiting full revelation. Each arm is more than a protocol. It is a symbol of how oncology now defines hope: by balancing efficacy against toxicity, progress against opacity, and survival against the integrity of truth revealed in stages.
