  • Overview

    HER2 is a well-established negative prognostic factor for metastatic breast cancer (mBC) and determining HER2 levels is essential for proper treatment decisions. Several studies have reported scoring inaccuracies for HER2 status, particularly in the low range (0 and 1+), and challenges with IHC assessment and interpretation can lead to the misassignment of many patients for treatment. Antibody-drug conjugates (ADCs), a new and promising class of therapeutics designed as targeted therapy for mBC, target and kill tumor cells while sparing healthy cells. Rapid advances in ADC development are transforming HER2-positive and HER2-low mBC patient outcomes. With recent FDA approvals of HER2-targeting agents and emerging positive trial data, clinicians and pathologists are faced with staying abreast of and integrating new treatment options into real-world clinical practice. 

    AXIS routinely collects and analyzes data gathered from participants in our live activities. These questions and answers provide incredible insight regarding testing methodologies to classify metastatic breast cancer according to HER2 status, addressing the strengths and limitations of different techniques. The clinical implications of these tests for guiding HER2-targeted therapies such as antibody-drug conjugates will be addressed, as well as evidence-based methods to address challenges such as treatment-associated adverse events and drug resistance, and key messages pertaining to the management of patients with metastatic breast cancer.

  • Learning Objectives

    After participating in this educational activity, participants should be better able to:

    1. Apply new strategies based on available detection methods and guideline recommendations to account for disease heterogeneity and properly assess HER2 status.
    2. Incorporate the accumulating body of evidence from current clinical trials and real-world data on ADCs and their implications in HER2-positive and HER2-low breast cancer into personalized patient treatment planning.
    3. Employ strategies to identify, mitigate, and manage potential treatment-related adverse events in patients receiving HER2-directed ADC therapies
