The first European Conference on Interventional Oncology (ECIO 2008/ET 2008) was organised by the CIRSE Foundation in April 2008, and was a great success. The scientific content, the quality of the presentations, and the overall number of delegates who attended the meeting exceeded even the best expectations.
In order to cater to the growing number of interventionists involved in oncology, the CIRSE Foundation organised another meeting dedicated entirely to interventional oncology: the second European Conference on Interventional Oncology (ECIO 2010) which took place on April 21-24, 2010, again in Florence, Italy.
In 2012, ECIO went from a biennial event to an annual fixture in the interventional radiological calendar. By making ECIO an annual event, CIRSE aims to support the advancement of interventional oncology as well as the interventional radiologists involved in it.
