IASIOS welcomes Centre hospitalier de l’Université de Montréal as the first Accredited Centre in Canada

April 16, 2026

Centre hospitalier de l’Université de Montréal has become the first IASIOS Accredited Centre in Canada, marking a significant milestone in the global advancement of interventional oncology standards. IASIOS is the only international accreditation system dedicated to interventional oncology worldwide, providing a structured framework to ensure safe, effective, and standardized patient care.


The International Accreditation System for Interventional Oncology Services (IASIOS) continues its global expansion with a major milestone in North America. Centre hospitalier de l’Université de Montréal (CHUM) has officially achieved IASIOS accreditation, becoming the first centre in Canada to reach this level of recognition.

This achievement reflects CHUM’s strong commitment to delivering high-quality, standardised, and patient-centred interventional oncology (IO) care. Interventional oncology offers minimally invasive, image-guided treatments that complement surgery, systemic therapies, and radiation, contributing to more precise and personalised cancer care. As one of Canada’s leading academic institutions, CHUM plays a key role in advancing multidisciplinary cancer treatment, and its accreditation marks an important step in aligning its IO services with internationally recognised best practices.

IASIOS was established to support the development and standardisation of IO services worldwide, ensuring safe, effective, and consistent care across the entire patient pathway. By achieving IASIOS accreditation, CHUM has demonstrated full compliance with the rigorous international standards defined in the CIRSE Standards of Quality Assurance in Interventional Oncology. These standards provide a comprehensive framework covering staff and facilities, treatment planning and delivery, and safety and quality, ensuring optimal patient outcomes.

This milestone not only represents an institutional achievement but also sets a benchmark for interventional oncology services across Canada. As the first IASIOS Accredited Centre in the country, CHUM paves the way for other institutions to follow, supporting the broader adoption of structured, high-quality IO care.

Dr. Ricardo Holderbaum Do Amaral, Assistant Clinical Professor in the Department of Radiology, Radiation Oncology and Nuclear Medicine, Faculty of Medicine at University of Montreal and Interventional Radiologist at CHUM, is leading the accreditation process, supporting the centre’s efforts to further develop and standardise its IO pathway.

“This accreditation reflects the rigorous work of our teams and our ongoing commitment to delivering excellence in care. In interventional oncology, our vision is clear: to provide treatments that are increasingly precise, safe, and tailored to the population we serve. At CHUM, we place patients at the heart of every decision, relying on innovation, interdisciplinary collaboration, and continuous improvement to sustainably enhance cancer care,” said Dr. Holderbaum do Amaral.

IASIOS’s continued growth reflects its global impact, with centres across Europe, North America, Asia, Australia, and the Middle East working together to advance interventional oncology. Through accreditation and membership, IASIOS fosters a collaborative international community focused on continuous improvement, education, and the promotion of IO as an essential component of modern cancer care.
