Investigators Discuss Available Research Guiding the Care of Patients with Ovarian and Endometrial Cancer — Symposium Video Proceedings

Faculty

TARGET AUDIENCE
This program is intended for medical and gynecologic oncologists, hematology-oncology fellows and other healthcare providers involved in the treatment of ovarian and endometrial cancer.

LEARNING OBJECTIVES

• Understand available clinical research findings with PARP inhibitors as maintenance therapy after first-line platinum-based chemotherapy for advanced ovarian cancer (OC), and appropriately counsel patients regarding personalized treatment recommendations.
• Evaluate the biological rationale for and published research data with PARP inhibitors in combination with other systemic therapies for advanced OC, and consider the clinical and research implications of these findings.
• Recall the mechanism of action of and current research findings with antibody-drug conjugates directed at FRα, and optimally integrate these agents into the care of patients with recurrent OC.
• Appreciate available clinical research findings with anti-PD-1/PD-L1 antibodies in combination with chemotherapy as first-line treatment for advanced or recurrent endometrial cancer (EC), and optimally incorporate this novel strategy into the care of patients with microsatellite instability-high/mismatch repair-deficient and microsatellite-stable/mismatch repair-proficient disease.
• Understand the biological rationale for and available data with PARP inhibitors in combination with immune checkpoint inhibitor therapy for patients with advanced or metastatic EC.
• Recognize available data with anti-PD-1/PD-L1 antibodies in combination with agents targeting the VEGF pathway, and select patients with metastatic EC for treatment with this novel approach.
• Evaluate published clinical research documenting the efficacy of HER2-targeted agents and regimens for HER2-overexpressing OC and EC, and consider the role of various approaches in the care of patients with these diseases.
• Describe the scientific justification for, published research with and ongoing studies of novel agents and strategies for OC and EC, and effectively prioritize clinical trial opportunities for eligible patients.
