[Current use and prospects for hadron therapy in 2015].
Hadron therapy (including protons and ions) is still expanding worldwide, although still limited by the cost and thus the number of available facilities. If the historical indications remain eye melanomas, skull base tumours and paediatric tumours for protontherapy; and salivary glands, paranasal sinus and nasal cavity tumours, and soft tissue sarcomas for carbon ions, no conclusion can be drawn about the role of these modalities for other tumours, such as prostate, lung cancers. Since 2013, more than 100 clinical trials are on-going, including comparisons between advanced photons modalities, protontherapy and carbon ions therapy. An important technological and scientific (physics, radiobiology) effort has been made in parallel in order to reduce the cost of the facilities and to fully take advantages of the beam properties: standardization of beam scanning, image guided treatment, robust and 4D planning. Furthermore, the increasing number of facilities, the development of hypofractionation and the selection of indications will contribute to find the true place of particle therapy, despite the "screening effect" of the cost. The long term effects assessment on large patient cohorts will allow or not to correlate adverse effects and dosimetric data, always evoked.
