Overview
Physicians’ Education Resource®, LLC (PER®), is pleased to present the 2026 International Symposium of Gastrointestinal Oncology® (ISGIO), a 2-day, multidisciplinary educational conference dedicated to presenting and discussing the latest advances in the broad field of gastrointestinal (GI) cancer research, as well as critical issues relevant to the care of persons with GI cancer.
Management of GI malignancies has evolved across all disciplines, from screening to prognostication to treatment approaches of all modalities. However, many patients do not fall neatly into guideline-based treatment, and the volume of clinical trial data makes it difficult to parse findings that should inform treatment.
This highly engaging conference brings together world-renowned experts from different disciplines to educate clinicians using a combination of case-based learning, debates, and panel discussions. This dynamic, multi-format program is designed to be a comprehensive review of the emerging treatment landscape for GI cancers, with the goal of elucidating the complex array of recent studies that should inform clinician practice.
Learning Objectives
Upon completion of this activity, learners will be better able to:
- Integrate biomarker testing results to individualize treatment selection for patients with GI cancers
- Evaluate the latest efficacy and safety data for newly approved therapies, novel combinations, and emerging agents in GI cancers
- Develop personalized treatment plans for patients with GI cancers based on current evidence and clinical guidelines
- Incorporate new clinical data to effectively sequence available therapies and optimize patient outcomes
- Apply evidence-based strategies to proactively monitor, prevent, and manage treatment-related adverse events in patients receiving novel therapies and combination regimens
