Anglo Celtic Cooperative Oncology Group

The Anglo Celtic Cooperative Oncology Group (ACCOG) is a non-profit clinical research organization and cooperative group dedicated to improving cancer treatment through rigorous clinical trials. Based in the United Kingdom and Ireland, the group focuses on the development and execution of multicenter Phase II and Phase III trials, with a historical emphasis on breast, esophageal, and gastric cancers. ACCOG collaborates extensively with academic institutions, the National Health Service (NHS), and pharmaceutical companies to validate novel therapeutic strategies and optimize chemotherapy regimens. The group's work is widely recognized for its impact on clinical practice guidelines and its contribution to the global oncology research community. It is particularly noted for the 'Anglo-Celtic' series of trials which have helped define standard-of-care protocols for various solid tumors.
