Author: Joelle Weaver MAOM, HTL(ASCP), QIHC
Reviewer: Carla Shoffeitt, MSM, HT(ASCP)

Toxicity, side effects, and unpredictable effectiveness have been the hallmark of anti-cancer therapies used in the past to treat breast and other primary cancers. Targeted therapies have been developed which reduce patient risk and provide remarkable improvement in patient outcomes. This course will discuss how predictive markers/testing are used to select patients who are most likely to respond positively to a specific breast cancer treatment, including current testing methodologies and compliance standards.

Objectives

  • Recognize the value of predictive test results to clinical treatment decisions in human breast cancer.
  • Identify the main types of predictive testing performed in the histology laboratory.
  • Determine test methodologies used to identify the expression and amplification of human epidermal growth factor receptor 2 (HER2).
  • Examine current test methodologies used to identify the expression and amplification of HER2.
  • Identify compliance standards for validation, correlation, and proficiency testing under the guidelines set by the College of American Pathologists (CAP).
