TARGET AUDIENCE
This program is intended for medical oncologists, hematologists, hematology-oncology fellows and other allied healthcare professionals involved in the treatment of breast cancer.

LEARNING OBJECTIVES

• Evaluate published research data in guiding the selection of therapy for patients with HER2-positive localized breast cancer.
• Implement a long-term clinical plan for the management of metastatic HER2-positive breast cancer, including in patients with CNS metastases, incorporating current and recently approved anti-HER2 therapies.
• Develop an understanding of the mechanisms of action of margetuximab, trastuzumab deruxtecan, tucatinib and neratinib and the clinical trial findings leading to the FDA approvals of these agents for previously treated, advanced HER2-positive breast cancer.
• Recognize common and rare side effects associated with novel anti-HER2 agents, and develop supportive management strategies to prevent and ameliorate these toxicities for patients with HER2-positive breast cancer.
• Appraise recent FDA approvals of and ongoing clinical research evaluating novel agents and treatment strategies for HER2-positive breast cancer, and counsel patients regarding protocol and nonresearch treatment recommendations.
