RESUMO
Among over 100 proton therapy centres worldwide in operation or under construction, French proton therapy is coming to full maturity with the recent opening of the Nice (1991, upgrade in 2016) and Caen (2018) facilities next to the Orsay (1991, upgrade in 2010) centre. Proton therapy is a national priority for children and young adults in all three centres. The patient-related activity of the three French centres is coordinated via the Protonshare portal to optimise referral by type of indication and available expertise in coordination with the French society of radiation oncology SFRO and French radiotherapy centres. The centres are recognised by the French Health Care excellence initiative, promoted by the ministry of Foreign Affairs. The three centres collaborate structurally in terms of clinical research and are engaged at the international level in the participation to European databases and research initiatives. Concerted actions are now also promoted in preclinical research via the Radiotransnet network. Ongoing French developments in proton therapy are well presented in international hadron therapy meetings, including European Proton Therapy Network and Particle Therapy Cooperative Oncology Group. Proton therapy teaching in France is offered at several levels and is open to colleagues from all radiation oncology centres, so that they are fully informed, involved and trained to facility recognition of possible indications and thereby to contribute to appropriate patient referral. This close collaboration between all actors in French radiation oncology facilitates the work to demonstrate the required level of medical and scientific evidence for current and emerging indications for particle therapy. Based on that, the future might entail a possible creation of more proton therapy facilities in France.
