Basic and clinical research for the new radiotherapy

Basic research has allowed the full knowledge of the underlying mechanisms of the use of radiotherapy in cancer treatment. However, in spite of the crop of radiobiological studies, the impact on clinical research in last years has been relatively little. Within the recent research in man, studies on altered dose fractionations, combined radiation and chemotherapy together with the development of sophisticated technology have allowed the use of new methods of radiotherapy while those existing have been optimized.
