We review the current state of development of proton therapy and the implications for beam therapy in the management of primary bone tumours The principle of radiotherapy is to deliver a high dose, accurately, to the tumour. Conventional photon and proton therapy irradiates adjacent tissue significantly. This is reduced with intensity modulation proton therapy (IMPT). This has been demonstrably effective in treating tumours refractory to chemotherapy and conventional radiotherapy such as chrondrosarcomas and chordomasStatement of purpose
