CE Information and Faculty Disclosures

  • TARGET AUDIENCE
    This program is intended for medical oncologists, breast surgeons, radiation oncologists and other healthcare professionals involved in the diagnosis and treatment of breast cancer.

    LEARNING OBJECTIVES

    • Appreciate the key clinical variables affecting preoperative therapy and the selection of a specific neoadjuvant regimen for patients with HER2-overexpressing localized breast cancer, and integrate this information into treatment decision-making.
    • Assess available Phase III data with HER2-directed antibody-drug conjugates as a component of neoadjuvant and adjuvant therapy for patients with high-risk localized disease, and consider the potential clinical role of this novel approach.
    • Evaluate published research data to guide the selection and duration of adjuvant and/or extended-adjuvant therapy for patients with HER2-overexpressing localized breast cancer.
    • Appraise available research data and clinical and biological factors to guide the selection of first-line therapy for patients with newly diagnosed HER2-positive metastatic breast cancer (mBC).
    • Appreciate the key clinical variables affecting the selection and sequencing of therapy for patients with relapsed/refractory HER2-positive mBC, and use this information to personalize treatment recommendations.
    • Design an optimal approach to the care of patients with HER2-positive breast cancer and CNS metastases, evaluating the implications of prior treatment exposure, symptomatology, extent of disease and other factors.
    • Recognize common and rare side effects associated with approved anti-HER2 agents, and use this information to develop supportive management plans for patients undergoing treatment for HER2-positive breast cancer.
    • Assess ongoing clinical research studies evaluating novel agents and treatment strategies under development for HER2-positive breast cancer, and counsel patients regarding the potential benefits of trial participation.
