[Proton therapy]

Proton therapy is an optimized radiotherapy technique. Today, the technical improvement provides reliable machines. The therapeutic indications are clearer even though therapeutic trials should confirm the current guidelines. A better knowledge in radiobiology could be useful if it is integrated in the treatment planning system. A new organization of care will definitively stabilize the number of patients for which treatment will be relevant. This organization will prepare the future expansion of this technique.
