Clinical Investigators Review Actual Cases of Patients with Endometrial Cancer — Webinar Video Proceedings

Faculty

TARGET AUDIENCE
This activity is intended for gynecologic oncologists, medical oncologists, gynecologists and other healthcare providers involved in the diagnosis and treatment of endometrial cancer.

LEARNING OBJECTIVES

• Assess the clinical and biological characteristics of various histologic subtypes and molecular subgroups of endometrial cancer (EC), and consider the implications of this information for prognosis, biomarker evaluation and therapeutic decision-making.
• Appreciate available clinical research findings with anti-PD-1/PD-L1 antibodies in combination with chemotherapy as first-line treatment for advanced or recurrent EC, and consider the current role of this novel strategy for patients with microsatellite instability-high/mismatch repair (MMR)-deficient or microsatellite-stable/MMR-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.
• Recognize adverse events associated with available and investigational therapies for EC to educate patients and manage complications.
• Describe the scientific justification for, published research data with and current studies of novel agents and strategies for EC, and effectively prioritize clinical trial opportunities for eligible patients.
