University Medical Center Groningen and RaySearch initiate collaboration within adaptive radiation therapy

RaySearch Laboratories AB has received an order for its RayStation® treatment
planning system from University Medical Center Groningen (UMCG) in Groningen,
the Netherlands. In conjunction with this, RaySearch and UMCG will also initiate
a new research collaboration project.

UMCG is one of the largest hospitals in the Netherlands and the largest employer
in the Northern Netherlands. More than 10,000 employees provide patient care,
are involved in medical education and perform cutting-edge scientific research,
focused on ‘healthy and active ageing’. Research and education at the UMCG are
funded through the University of Groningen, and the Faculty of Medical Sciences
functions as an integral part of the University. More than 3,400 students of the
University of Groningen study Medicine, Dentistry or Human Movement Sciences,
while more than 340 physicians are doing their specialty training at the state
of the art facilities of the UMCG.

RaySearch and the department of Radiation Oncology of UMCG have a longstanding
research cooperation that will now be focused on adaptive radiation therapy
using RayStation®. Adaptive therapy is an advanced form of radiation therapy
where the delivered dose is adjusted continuously during the course of treatment
to account for changes occurring in the patient’s anatomy. This has a
significant potential to increase the tumor control probability and at the same
time reduce the risk for side effects by sparing healthy tissue. UMCG and
RaySearch will now collaborate to introduce adaptive radiation therapy in
clinical practice and further refine and evaluate the methods involved.

“RaySearch is a pioneer in the development of advanced software tools for
radiation therapy and our longstanding cooperation is highly important for our
department. RayStation® is the leading tool on the market for adaptive radiation
therapy and we are very excited to start implementing this concept with a
significant potential to improve cancer care”, says Prof. Johannes A.
Langendijk, chair of the Department of Radiation Oncology at University Medical
Center Groningen.

“UMCG is a well-renowned clinic and have proven over the years that they
maintain an excellent standard in cancer research. I am therefore convinced that
this collaboration will be very fruitful and will make meaningful contributions
to the area of adaptive radiation therapy which is the most important new
concept in radiation therapy”, says Johan Löf, CEO of RaySearch. “
