Dynamics of ESR1 Alterations and Serial Liquid Biopsies

Author(s)Virginia G. Kaklamani, MD, DSc, Heather McArthur, MD, MPH

In their discussion, medical experts in the field of breast cancer explore the role of liquid biopsies and compare the significance of ESR1 mutations to other biomarkers, such as PIK3CA, in terms of their driver versus passenger status in the context of HR+/HER2- breast cancer.
