Clinical Investigators Provide Perspectives on the Current and Future Clinical Care of Patients with Metastatic Breast Cancer — Symposium Video Proceedings

Faculty

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

LEARNING OBJECTIVES

• Evaluate recently presented clinical research findings to determine their effect on the current management of metastatic breast cancer (mBC).
• Review the correlation between various biomarkers (eg, PIK3CA/AKT1/PTEN alterations, ESR1 mutations, low and ultralow HER2 levels) and response to specific therapies, and develop optimal testing algorithms for patients with hormone receptor (HR)-positive mBC.
• Appraise published efficacy and safety data from randomized clinical trials evaluating CDK4/6 inhibitors for HR-positive mBC, and appropriately counsel patients regarding the optimal use of these agents.
• Recall the frequency of phosphoinositide-3 kinase pathway mutations in patients with HR-positive mBC, and recognize the evidence-based approaches available to target these aberrations in individuals with PIK3CA-mutated disease.
• Understand the mechanism of action of, published and emerging research findings with and the current and future clinical role of oral selective estrogen receptor degraders for patients with HR-positive mBC harboring ESR1 mutations.
• Interrogate published Phase III research documenting the efficacy of AKT inhibitors for patients with progressive HR-positive mBC to determine the current clinical applicability of this approach.
• Appreciate the incidence, characteristics and clinical relevance of HER2-low or ultralow mBC, and understand available research findings with HER2-directed antibody-drug conjugates for this disease subset.
• Assess published and emerging Phase III research documenting the efficacy of TROP2-directed antibody-drug conjugates for mBC in order to determine the current and potential clinical applicability of these approaches.
• Evaluate published and emerging research findings and biological and clinical factors to effectively select and sequence available therapeutic agents and regimens for patients with HER2-positive mBC.
• Review published research supporting the use of chemotherapy in combination with anti-PD-1/PD-L1 antibodies for patients with triple-negative mBC, and use this information to make appropriate treatment recommendations.
• Discuss available research establishing the efficacy of PARP inhibitors for patients with mBC harboring BRCA or other homologous recombination repair pathway mutations, and identify individuals appropriate for treatment with these agents.
• Recall the mechanisms of action of, early data with and ongoing clinical trials evaluating other novel agents and treatment strategies under development for mBC.
