Advances in molecular and clinical subtyping of breast cancer and their implications for therapy.
Review
Overview
abstract
The identification of the intrinsic molecular subtypes of breast cancer has enhanced our understanding of tumor biology, informing therapeutic targets, and clinical trial design. This article reviews the intrinsic classification system and the clinically defined subtypes of breast cancer. We review the molecular drivers of each subtype and discuss implications for prognosis, clinical management, and future directions.
