Abstract : The Arsène Burny Cancer Institute (ICAB) of the CHU de Liège is the reference university medical center, open to its environment, dedicated to cancer care. Transversality, academic expertise, quality of care and direct links with research are at the heart of this ambitious achievement, which is much more than a building. The Integrated Center of Oncology (CIO) is the new ICAB building, dedicated to outpatient cancer care and high performance technical platforms such as radiotherapy with its Cyberknife, oncology imaging with its radiopharmacy, the Laboratory of Cell and Gene Therapy, the Liège University Hospital Biobank, or the laboratories grouped together within Unilab, while hospitalizations remain in the existing towers of the CHU.
