The 2025 European Conference on Interventional Oncology (ECIO) was held in Rotterdam, the Netherlands, from April 13–16, bringing together over a thousand interventional specialists from around the world.

Led by Chairperson Prof. Laura Crocetti and Deputy Chairperson Prof. Jean Palussière, the scientific programme committee dedicated great efforts to developing a comprehensive meeting that reflected the growing range of treatments interventional oncology provides. Topic highlights this year included revolutions in HCC treatment, immuno-oncology, paediatric IO, the ECIO meets sessions, and basic courses on breast, thyroid, and prostate care.
As in previous years, ECIO 2025 was preceded by the IO Foundation Course, held the day before the main congress. This introductory session offered aspiring young interventionalists valuable insights into IO’s place within the broader landscape of cancer treatment.
Throughout the congress, the importance of interventional oncologists within multidisciplinary teams was a central theme. ECIO met with the International Liver Cancer Association (ILCA), the European Neuroendocrine Tumor Society (ENETS), and the European Association of Urology (EAU).
The Collaborating Against Cancer Initiative once again allowed IOs attending ECIO to bring a tumour board colleague along to the congress free of charge in order to promote multidisciplinary collaboration and help other specialties gain a better understanding of what interventional oncologists bring to the table. More than a dozen IOs participated in the programme, bringing oncologists, radiation oncologists, surgeons, urologists, gastroenterologists, and more to participate in the meeting alongside IOs and radiologists.
ECIO 2025 included extensive options for attendees to gain hands-on experience in several areas. Tumour ablation sessions focused on heat-based, non-thermal, and cold-based ablation as well as on planning, robotics, monitoring and assessment for ablation. The safe sedation sessions offered both a basic and advanced session for sedation application during IR procedures and one session dedicated to Propofol. Radioembolization sessions were offered on dosimetry and administration systems, and two sessions were held on MSK IO interventions.
While most scientific sessions are available to watch on demand, only in-person attendees could take advantage of the interactive activities offered on-site. The meeting included several quizzes, competitions, meet-ups, and networking receptions, and all of CIRSE’s initiatives were represented in the exhibition hall.
ECIO 2026 will take place from April 26-30 in Basel, Switzerland. The Scientific Programme Committee is already hard at work on next year’s programme. Until we meet again, you can help spread the word about ECIO 2026 with our promo materials!
