Would you offer adjuvant AI + abemaciclib to a post-menopausal, node + luminal A breast cancer that did not require chemotherapy per Oncotype, yet still met criteria per monarchE?   

- monarchE included <1% Stage IA and < 5% patients with no chemotherapy.

Ex: 64 yo, ER/PR 95%, Ki67 20%, cT1c N0 but pT1c N1a at lumpectomy/SLN biopsy with Oncotype 16.
