Red flags — PRO / CONTRA aggressive

PRO-AGGRESSIVE

Triggers that push toward the aggressive track
  • HER2-ultralow breast cancer (IHC > 0 < 1+; faint/incomplete membrane staining ≤10% of tumor cells) — a sub-tier between IHC 0 and IHC 1+ not part of standard ASCO/CAP scoring. DESTINY-Breast06 (Bardia 2024 ASCO plenary) extended T-DXd benefit beyond HER2-low to HER2-ultralow HR+ metastatic breast post-endocrine + CDK4/6i, chemo-naive in the metastatic setting (HER2-low cohort mPFS 13.2 vs 8.1 mo, HR 0.62; HER2-ultralow exploratory n=153 mPFS 13.2 vs 8.3 mo, HR 0.78). FDA label expansion anticipated 2026 — candidate RF until pivotal-trial Source SRC-DESTINY-BREAST06-BARDIA-2024 ingested. RF-BREAST-HER2-ULTRALOW-CANDIDATE
