The 2026 Global Cardio-Oncology Summit (GC-OS) will be held from October 5–7, 2026, in Williamsburg, Virginia.

Hosted by the International Cardio-Oncology Society (IC-OS), this premier interdisciplinary event is centered on the theme “Cardio-Oncology Innovation and Implementation for the Future.” It serves as a global platform for cardiologists, oncologists, and researchers to address the cardiovascular challenges faced by cancer survivors.

The scientific program focuses on cutting-edge clinical frontiers, including the integration of artificial intelligence in diagnostics, new treatments for cardiac amyloidosis, and the role of the immune system in cardiovascular health. Key sessions will cover multimodality cardiac imaging, next-generation therapies in hematology, and evidence-based exercise interventions designed to mitigate cardio-toxicity.

Beyond the core lectures, the summit emphasizes global networking and early-career development through the Young Investigator Award competition on October 7. Set in the historic Williamsburg Inn, the event balances rigorous academic exchange with the cultural backdrop of one of the U.S.’s most significant historical sites, providing an ideal environment for professional collaboration and the presentation of original research.
