Charged particles therapy in radiation oncology

The physical and biological features of using protons and heavy ions in the treatment of malignant tumours were reviewed. It is showed that proton therapy is an effective method for treatment of malignant tumours, which has certain benefits comparing photon therapy. This modality may be recommended to 10-15 % of oncological patients. Carbon ion radiation therapy is especially perspective as it has local relative biological effectiveness till 2,0-3,5. The clinical efficacy of charged particles therapy at most expansive tumours was revealed. The cost efficacy of this type of radiation therapy was given. Key words: proton therapy, ion therapy, charged particles therapy, clinical efficacy of charged particles therapy.
