The Paediatric Radiation Oncology Society (PROS) invites colleagues from around the world to participate in the PROS Education Day in conjunction with the International Society of Paediatric Oncology (SIOP) Congress.  The PROS Educational Day will be held at the Lyon Convention Center in Lyon, France, on October 23, 2019.  During the SIOP Congress there will be a PROS Symposium on the Management of Rhabdomyosarcoma as well a multidisciplinary session with the International Society of Paediatric Surgical Oncology (IPSO) and SIOP which will address Treatment Concepts and Challenges in Unresectable Pediatric Solid Tumours. There will also be the D’Angio Keynote Lecture.

In collaboration with PROS, the SIOP website will allow member registration, online meeting registration and submission of abstracts. We encourage you to visit our website ( and register quickly as a PROS member. PROS members will benefit from reduced registration fees and access to important sections of the website such as a forum for discussion of critical cases, a directory and the PROS newsletter. SIOP serves our members well and will encourage other radiation oncologists interested in the treatment of Paediatric cancers to become involved in PROS and to participate in the following SIOP Congress.

We are looking forward to seeing you in Lyon, France in October 2019!
