European Particle Therapy Network (EPTN)

The European Particle Therapy Network (EPTN) became a task force of ESTRO in 2017. It was established in 2015 in response to the anticipated increase in the number of particle therapy centres in Europe. In addition, the need to cooperate among centres and integrate particles (i.e. protons and carbons) in the framework of clinical research networks was identified as being of paramount importance. ESTRO, at the time of initiation of the network, was asked to collaborate with EPTN and agreed to facilitate the group.

Particle therapy (PT) is only one part of radiation oncology, and needs to be well aligned with other radiation techniques as well as with general developments in cancer research and patient care. PT offers both new opportunities for providing excellence in cancer care, and for high-quality research within the framework of European  networks.

Organisation

The EPTN is led by three co-chairs and is composed of 8 working packages (WP) with experts of different topics to further elaborate the particle European discussions.
The EPTN meets once a year through the EPTN annual meeting.

The EPTN co-chairs are:

• Cai Grau (Aarhus, DK) 
• Damien Weber (Villigen, CH) 
• Dietmar Georg (Vienna, AT)

The EPTN has its own internal standard operating procedure (SOP), covering its policies, aims, and organisation of the network.

EPTN Work Packages

Each WP is structured with one or more coordinators and is thematically established to cover key challenges and developments related to the EPTN and its work. Some of the core responsibilities and aims of the WPs consist chiefly of engaging in trials, guidelines, white papers, and surveys, as well as establishing and hosting workshops and courses.
Below, each work package is listed with its own dedicated section, outlining its general organisational structure, as well as any particular developments and news from the work package.

Work Package 1: Clinical Evidence

Coordinators:
Hans Langendijk, The Netherlands
Karin Haustermans, Belgium

Work Package 2: Quality assurance

Coordinators:

Work Package 3: Education

Save the date: RTT Workshop – Paul Scherrer Institute (PSI), Switzerland 15th and 16th November 2024

This workshop for RTTs by Working Package 3 on Education of the EPTN, is aimed at discussing immobilisation, imaging, and the psychological impact of particle therapy. We seek to build up a strong RTT community in the EPTN, learn from each other in order that together we may find solutions for our everyday problems.

The workshop will be held at the Paul Scherrer Institute in Switzerland from the 15th to the 16th of November 2024.

Work Package 4: Image guidance

Save the date: EPTN-WP4 Annual Workshop on 21st and 22nd of November 2024, in Delft, Netherlands!   The annual workshop of the EPTN Work Package 4 on “Image Guidance in Particle Therapy” will take place on the 21st and 22nd of November 2024 at HollandPTC in Delft, the Netherlands. The EPTN WP4 coordinators, Alessandra Bolsi and Aswin Hoffmann, kindly invite you to save-the-date for this workshop and hope that you will be able to participate. Further information regarding registration, as well as travel and venue information will follow soon. Please find the agenda below, under "Events". Looking forward to seeing you at HollandPTC in Delft in November!

Coordinators:
Aswin Hoffmann, Germany
Alessandra Bolsi, Switzerland

Aims:

• Consolidate existing knowledge
  Gather and synthesize information on current clinical experience, guidelines and research related to IGPT to establish a comprehensive understanding of its principles and applications.
• Identify clinical practice parameters and patterns
  Systematically identify clinical practice parameters and patterns regarding IGPT, aiming to standardise treatment protocols, optimise workflows and provide excellence in patient care across institutions.
• Develop evidence-based consensus guidelines
  Systematically collect and review available evidence to formulate evidence-based recommendations for the minimum clinical and technical requirements for IGPT in different cancer types, treatment settings and patient populations.
• Facilitate collaborative research
  Stimulate collaboration among researchers and institutions to conduct high-quality multicentric studies aimed at advancing the understanding and refining the practice of IGPT, with the aim to standardise treatment protocols, optimise workflows and improve treatment outcomes.
• Promote education and awareness
  Foster education and awareness among all professional sub-disciplines about the appropriate utilisation of IGPT through the organisation of the annual workshop and the dissemination of practice patterns and consensus guidelines.
