Case Overview: Early-Stage Breast Cancer During COVID-19

T-DXd and Dato-DXd are now approved treatments in Japan for patients with breast cancer.

Data from the phase 3 EMBER-3 trial support the full approval of imlunestrant plus abemaciclib in this breast cancer population.

NICE recommended trastuzumab deruxtecan for reimbursement in England for HER2-low metastatic breast cancer, backed by DESTINY-Breast04 data.

Trastuzumab botidotin more than doubled median PFS vs trastuzumab emtansine in HER2-positive advanced breast cancer in the phase 3 KL166-III-06 trial.

Camizestrant/palbociclib did not significantly improve PFS vs anastrozole/palbociclib in first-line ER+/HER2– breast cancer in the phase 3 SERENA-4 trial.

Erica L. Mayer, MD, MPH, discussed the practical questions clinicians must answer as the SERENA-6 early-switch approach with camizestrant enters practice.

Erica L. Mayer, MD, MPH, explained why oncologists should switch to camizestrant at ESR1 mutation emergence rather than reserve oral SERDs for progression.

Adding atezolizumab to neoadjuvant chemotherapy did not significantly improve EFS in early TNBC, but node-positive and high-TIL subgroups showed benefit.
