The ECIO 2021 programme will again cover a broad spectrum of relevant topics – from well-established therapies, such as local ablation for liver tumours, to newer clinical areas, such as immunotherapy – all to be explored within a variety of session types. Clinical focus sessions will provide updates on the latest evidence in interventional oncology, whereas the technical focus sessions and a video learning session will showcase technical tips and tricks for interventional oncology treatments. The basic course for beginners will this year focus on genitourinary and will offer three distinct sessions.
