Periodic Reporting for period 3 - INSPIRE (INfraStructure in Proton International REsearch)
Periodo di rendicontazione: 2021-03-01 al 2022-12-31
Proton Beam Therapy (PBT) is a new type of advanced radiotherapy capable of delivering and conforming a targeted dose of radiation to the tumour while causing minimal damage to the surrounding healthy tissue.
INSPIRE comprises 17 European centres to form a highly specialised research infrastructure in high energy PBT. The consortium is made up of internationally leading research and clinical facilities and industry including an SME. INSPIRE collaborates with EU Networks (ARIE) and with other EU projects (UHDPulse and HITRI-plus). INSPIRE is part of the EU canServ infrastructure.

VARIAN continued to develop their new detector technology (WP10) for FLASH PBT. This is a non-CE marked device, available commercially and has been used in the world’s first FLASH PBT clinical trial FAST-01 and now being used in a subsequent trial FAST-02. VARIAN developed this commercial product, in part through INSPIRE’s Innovation Gateway (WP5). Work conducted with AU demonstrated that this device could be used clinically at both FLASH and conventional dose rates. In addition, Varian worked with PTW-Freiburg, a partner of another related EU project (UHDpulse) on modified dosimetry equipment for qualification of ultra-high dose rate proton beams. Varian also worked with GSI Darmstadt and THM Gießen applied for testing 3D printed range modulators for fast delivery of custom-designed spread out Bragg peak FLASH. An article was prepared by VARIAN to highlight INSPIRE and the collaborations that have led to these developments.
An international benchmarking study led by TUD across PBT centres (WP9) is allowing the harmonization of LET calculations and RBE reporting following proton therapy. This work has now been published.
INSPIRE working with the founders of the FLASH Workshops, UHDPulse and Kenes on a new conference series Flash radiotherapy and Particle Therapy (FRPT) https://frpt-conference.org/. Due to the Omicron variant of Covid-19 the first conference in Dec 2021 had to take place virtually. This attracted over 700 people from over 40 countries. The next conference took place in Barcelona 30 Nov-2 Dec 2022 with over 650 people; 450 in person from 41 different countries. The third is scheduled for Toronto 5-8th Dec 2023. Selected papers from the conference have been published in a special edition of the Green journal (Radiotherapy and Oncology). The conference series is endorsed by ESTRO.
The CAPTAIN database (WP8) developed by IBA/UMCG has been further developed and the NTCP models it now includes has significantly increased. CAPTAIN is available as an Open Source platform.
