One Global Network Advancing Head & Neck Cancer Research Connecting Experts. Accelerating Discovery. Improving Lives. The Head and Neck Cancer International Group (HNCIG) is a global collaborative network dedicated to advancing research and improving outcomes for patients with head and neck cancers through international cooperation. HNCIG brings together leading academic cooperative groups, cancer centres, and investigators from across the world to develop and conduct high-quality clinical research, generate robust evidence, and harmonise clinical trial methodologies. Through multidisciplinary collaboration, the group seeks to accelerate innovation in clinical trials, facilitate global data sharing, and enable studies that would not be possible within individual national networks alone. Today, HNCIG connects 23 member organisations across 39 countries, creating one of the largest international research collaborations in head and neck oncology. By aligning expertise across continents, HNCIG strengthens the ability of the global oncology community to address key scientific questions and improve patient care worldwide.
