Collaborating against cancer at ECIO 2025

January 16, 2025

The Collaborating Against Cancer Initiative (CACI) enables IRs and radiologists to bring their non-radiologist colleagues to the European Conference on Interventional Oncology at no extra charge. Since its inception, this initiative has been embraced by many teams and become a cornerstone of the meeting. In addition to free registration, participating non-radiologists can apply for up to €1,000 in travel support.

“ECIO is not just a European congress, but an international one,” said Prof. Zoran Trajkovski, an interventional radiologist who attended the meeting alongside an IR colleague and two of their clinical oncology colleagues. “Experts worldwide can share their experiences and the latest research findings. Attending this congress allows us to stay updated and discuss valuable information within the team.”

“I strongly believe that being here at ECIO broadens our perspective,” said Dr. Daniela Poposka, a clinical oncologist. “It makes us better doctors for our patients and better colleagues for our peers.”

Read on to hear perspectives on the importance of this initiative from several more participants in in the Collaborating Against Cancer Initiative at ECIO 2024!

Prof. Zoran Trajkovski, interventional radiologist and Dr. Deva Petrova, radiation oncologist – North Macedonia
Dr. Daniela Poposka, clinical oncologist and Assoc. Prof. Aleksandar Gjoreski, interventional radiologist – North Macedonia
Dr. Trygve Syversveen, radiologist and Dr. Ingrid SchIøder Hansen, surgeon – Norway 

Dr. Deva Petrova, radiation oncologist, North Macedonia:
“At ECIO, I felt like we are all together at one table with other specialties, and we could talk and see how each field approaches different cases. We discussed questions like: What are the indications and contraindications? What are the possibilities where we can combine methods to improve treatment outcomes? I am really happy to have the opportunity to attend this event and learn from it.

I think attending this congress will impact my daily practice. One lecturer’s presentation summed it up perfectly: ‘If you want to go fast, go alone. If you want to go far, go together.’ This meeting provided valuable insights into interventional oncology results, indications, and advancements, which can enhance our national protocols and improve decision-making for patients.

In particular, I found the case presentation sessions to be fascinating. They showed real-life cases and how experienced doctors tackled challenges in their hospitals. The debates were incredibly insightful.”

Assoc. Prof. Aleksandar Gjoreski, interventional radiologist, North Macedonia:
“I think this is a great opportunity that ECIO offers, not only for us as IRs but also for the entire multidisciplinary tumour board. We can learn from each other and gain more knowledge about our respective specialties. And with this, we can improve our services for cancer patients.

I especially enjoyed multidisciplinary sessions where I could learn from colleagues in oncology, surgery, and radiotherapy. Understanding different perspectives helps us collaborate more effectively.”

Dr. Ingrid SchIøder Hansen, surgeon, Norway:
“Joining the interventional radiologists and oncologists at this conference gives us a shared understanding of the different possibilities and limitations of different treatment options. This makes it easier for us to make joint decisions.

I would recommend this initiative, as it provides valuable updates on treatments and is a great way to connect with colleagues who share an interest in liver tumour management.”

Dr. Alexander Villalobos, interventional radiologist and Dr. Sara Westergraad, radiation oncologist – USA
Dr. Alios Komarek, radiologist and Dr. Anja Lachenmayer, surgeon – Switzerland
Dr. Mihaela Birligea, gastroenterologist and Dr. Eduard Dumea, interventional radiologist – Romania

Dr. Mihaela Birligea, gastroenterologist, Romania:
“I think it’s very important to see how my colleagues handle these complex patients, as they require a multidisciplinary team approach. This collaboration is vital for gastroenterologists and interventionalists alike.

When we think of radiologists, we often only associate them with interpreting CT or MRI scans. However, this meeting changed my perspective, showing how we can collaborate with IRs on interventions for our patients.”

Dr. Alios Komarek, radiologist, Switzerland:
“Sometimes in a procedure, we must make a last-minute decision, even after the tumour board’s decision, because sometimes conditions change in the weeks leading up to a procedure. This initiative enables us to collaborate as a team to make safe, last-minute decisions based on our combined knowledge and experience.

Oncology has become a huge field of research and discoveries, and so many experts are involved in this area. I would like to take some more colleagues to ECIO and show them how we as IRs see it and how we can work together as a team. We’re not strong enough on our own. We need to work together, as a team I believe we can go much further.”

Dr. Alexander Villalobos, interventional radiologist, USA:
“How one specialty sees the other can sometimes feel like a black box during tumour board discussions. By allowing colleagues from different specialties to come learn what IRs do, the Collaborating Against Cancer Initiative has helped shine a light on understanding each other’s perspectives. This opportunity has allowed me to show my tumour board colleagues what IRs can do, further strengthening collaboration and bridging the gap between our specialties.”

Other congresses have previously encouraged IRs to bring their non-IR colleagues to the conference. However, I think ECIO is the first major congress I’ve seen that has actually provided funding to support this effort. Specifically, CACI has helped cover the full registration fee, which is often the biggest barrier to inviting a colleague to attend. Overall, this initiative has significantly reduced the barriers for IRs to invite other non-IR colleagues to attend this multidisciplinary conference.”

Dr. Sara Westergraad, radiation oncologist, USA:
“This opportunity familiarized me with various procedures that are offered in interventional radiology and the differences between the two specialities. Now, I’m more familiar with the tools in the toolbox for all my patients, even tools outside of radiation oncology.

I went to the ESTRO meets ECIO session, which I found particularly helpful. It was good to learn a little bit more about the data behind some of the techniques that IR uses. I also found useful that there was talk about immunotherapy with radiation therapy and interventional radiology. I didn’t even realize that was a thing, so I really enjoyed learning more about that.”


Registration for ECIO 2025 is currently open – if you plan on bringing your tumour board colleague to ECIO 2025 through the Collaborating Against Cancer Initiative, simply register your colleague at the same time you register yourself.

“Bringing colleagues from other specialties, such as gastroenterologists or oncologists, leads to richer discussions,” stated Dr. Eduard Dumea, an IR from Romania. “It really helps you grow as a person and as a practitioner, and I would like to get more chances like this, as it has such an impact. My colleague now sees the value we bring to the table and can share this understanding with others. Building trust and collaboration is vital for delivering the best care to our patients.”
