eCase - Role of the MDM2-p53 Pathway in BTC

Introduction

In this module, Patricia LoRusso, DO, PhD(h) reviews the current guidelines and recommendations for molecular testing in advanced biliary tract cancer (BTC) and puts into context the rationale for targeting MDM2/p53 signaling in BTC with a review of how the most relevant and up-to-date data on an emerging novel agent targeting this pathway in BTC may improve outcomes for patients in the future.

The key points discussed in this module are illustrated with thumbnails from the accompanying downloadable PowerPoint slideset, which can be found here or downloaded by clicking any of the slide thumbnails alongside the expert commentary.
