Welcome to ILEXIUM

Live & in-person in Bonn

As the positive development of the COVID-19 pandemic gradually allows for more freedom again, also the long-desired live congresses with podium speeches, poster presentations and face-to-face meetings are slowly becoming reality again – also ILEXIUM!

Therefore, it is our greatest pleasure to invite you to the upcoming International Low Energy X-ray IORT User Meeting (ILEXIUM) which will take place on 07 – 08 March 2022 in the historical city of Bonn, Germany to address topics concerning intraoperative radiotherapy (IORT) and give the IORT community the possibility to finally meet and socialize face-to-face again. The event is officially hosted by ZEISS and takes place in consideration of the official COVID-19 regulations of the Federal Republic of Germany.

Elena Sperk, MD
University Medical Center Mannheim,

We are delighted to have you with us to participate in the first post-pandemic ILEXIUM in 2022. This conference has come a long way and yet it has surpassed the various challenges that our health systems have faced over the last two years. This year, it holds two special values: …

Frank A. Giordano, MD
University Hospital Bonn,

Warm regards, Elena Sperk & Frank A. Giordano (Conference Chairs)

… First, it is held as an in-person event after a long period of dry and exhausting video sessions. Second, it is - for the first time - not taking place in Mannheim, but in Bonn, the city of Beethoven and former capital of the Federal Republic of Germany. Please enjoy the live meeting and the great program we have compiled.

Scientific program

Exchange & Inspire

The scientific program of ILEXIUM will provide a wealth of information about intraoperative radiotherapy, ongoing clinical trials and study results, as well as the latest advancements and further developments of IORT. In addition, it is a splendid opportunity to directly learn from your peers and get first-hand experiences about IORT in the clinical practice.

We would like to encourage you to be part of this exciting IORT community and actively contribute to the scientific program with oral presentations and poster sessions. As a special highlight we will sponsor one hotel night including breakfast at the Maritim Hotel Bonn for the first 30 submitted abstracts. One complementary hotel night per person.

Take your chance, make this event unique & submit your abstract now!

Preliminary Program

The meeting starts with a warm welcome by the conference chairs, Frank A. Giordano and Elena Sperk, followed by the scientific program which is categorized in various topics and each category is chaired by leading international experts.

Following the scientific program, we would like to invite you to an evening reception at the Kameha Grand Bonn and enjoy the evening with you in a pleasant and relaxed atmosphere. Be excited – another highlight awaits you.
