An informative survey with detailed explanations will evaluate current approaches to HER2 testing and interpretation, and help refine assessment precision to provide medical oncology colleagues with the most up-to-date and accurate test results, which will expand treatment options for patients.
 

Learning Objectives

Upon completion of this activity, participants should be able to:

  • Review updated categories of HER2 expression for breast tumors, with a focus on the categories of HER2 low and HER2 ultralow
  • Apply the latest approaches to interpreting HER2 staining patterns to appropriately communicate expression levels in the pathology report
  • Summarize the latest clinical trial data of antibody-drug conjugates for the treatment of HER2-low and -ultralow, metastatic and/or relapsed/refractory advanced BC
