Tess O’Meara: monarchE at ESMO 2025 – Advancing Outcomes in Early ER+ Breast Cancer

Tess O’Meara, Hematology/Oncology Fellow at Dana-Farber Cancer Institute, shared a post on LinkedIn:

“Excited to to share that my editorial, mentored and co-authored by Dr. Harold Burstein, is published in Annals of Oncology today to accompany the updated overall survival results from the monarchE clinical trial.

Practice-affirming monarchE data were presented at ESMO – European Society for Medical Oncology in Berlin today, showing improvement in patient survival at 7 years with the addition of CDK4/6i abemaciclib to endocrine therapy for high-risk, early-stage ER+ breast cancer.

We tackle the questions:

– Which patients benefit most from the addition of adjuvant CDK4/6i?
– Which patients might be spared the extra side effects, like diarrhea and low blood counts, by foregoing these therapies?
– How do we interpret overall survival results from adjuvant ER+ breast cancer trials, where recurrence can occur years after upfront treatment?”
