International Accreditation System for Interventional Oncology Services



In order to become an IASIOS enrolled centre, and receive the first seal of recognition, your facility must meet the following criteria:

  • Performs a minimum of 150 interventional oncology procedures per year (or will meet the number of procedures by the time you submit the application for accreditation)
  • Have approval for enrolment from an appropriate authority (Head of Department or Hospital Director, etc.)
  • Have allocation of funds; keep in consideration that the IASIOS fees will be issued upon enrolment
  • Agree to the terms and conditions
  • Being familiar with the Standards of QA in IO, and a commitment to work on meeting all of the core criteria for accreditation set in the standards

IASIOS does not put restrictions on medical facilities regarding their size or location. Any facility that wishes to obtain formal recognition of their IO service line is able to apply for IASIOS, either as part of an existing institution or as an independent entity

If you are ready to enroll, register your facility here.


To achieve the seal of IASIOS Accredited Centre, you must meet all core requirements outlined in the Standards of Quality Assurance in Interventional Oncology, as well as complete an internal case review of 30 randomly selected patients.

Check how your facility compares to the core criteria in the checklist below, and how your patient records compare to minimum dataset.
