Gastrointestinal Cancer Science Highlights

This session highlights five of the most clinically relevant abstracts within the Gastrointestinal track of the 2022 ASTRO Annual Meeting Scientific Program. These noteworthy scientific abstracts share important findings and feature cutting edge research from leaders in the field. The Discussant compares and contrasts the current data to help you digest the latest science; places the study into context; and describes how the study can be put into clinical practice, if recommended. 
Highlighted Abstracts include – 

  • NRG/RTOG 1112: Randomized Phase III Study of Sorafenib vs. Stereotactic Body Radiation Therapy Followed by Sorafenib in Hepatocellular Carcinoma 
  • Long Term Result of a Multi-institutional Phase II Study of Hypofractionated Proton Beam Irradiation of Unresectable Primary Liver Tumors 
  • Patient-reported Outcomes (PROs) in NRG Oncology RTOG 1010: Phase III Trial Evaluating the Addition of Trastuzumab to Trimodality Treatment of HER2 Overexpressing (HER2+) Esophageal Adenocarcinoma (EAC) 
  • Multi-Institutional Comparison of Ablative Radiation Therapy in 5 vs. 15-25 Fractions for Locally Advanced Pancreatic Cancer 
  • Non-operative Management is Feasible and Safe in Patients with Rectal Cancer who Achieve Clinical Complete Response to Short-course Radiation Therapy and Consolidation Chemotherapy
