CE Information and Faculty Disclosures

  • TARGET AUDIENCE
    This program is intended for medical oncologists, hematology-oncology fellows, surgeons and other healthcare providers involved in the treatment of gastrointestinal (GI) cancers.

    LEARNING OBJECTIVES

    • Appreciate the prevalence and clinical relevance of human epidermal growth factor receptor 2 (HER2) amplification or overexpression in various GI cancers, and consider the implications for biomarker assessment and clinical management.
    • Evaluate published clinical trial findings with HER2-directed therapies for HER2-positive biliary tract cancers, and optimally incorporate available agents into the clinical care of appropriately selected patients.
    • Review published and emerging research findings with HER2-targeted therapies for patients with HER2-positive gastroesophageal cancers, and assess the current and future role of various agents and regimens.
    • Recall available data with HER2-targeted agents and strategies for patients with previously treated HER2-overexpressing colorectal cancer, and optimally identify candidates who may be appropriate for these approaches.
    • Appraise the side effects associated with HER2-directed therapies with established efficacy in GI cancers, and use this information to develop supportive management plans for patients.
    • Recall the design of ongoing clinical trials evaluating novel HER2-directed strategies for HER2-positive GI cancers, and counsel appropriately selected patients about availability and participation.
