It is known that the treatment of the central nervous system (CNS) tumors is based on the use of surgery and radiotherapy (RT) and that chemotherapy (QMT) is used even more, as well as the other drugs. A bibliographic review was made to update the knowledge on the current trends and perspectives of RT applied to CNS tumors. The following were found among them: a) combinations of RT and CMT; b) radiosensibilizers incorporated to the radiant treatment; c) angiogenesis inhibitors associated with RT; d) the scale-up or increase of the RT doses thanks to the development of new technologies, such as 3 D conformal radiotherapy, intensity- modulated radiotherapy, surgery and others. Another field of research is that of the changes in the rhythm or fractioning of the RT: hyperfractionated, accelerated, combinations of both, etc., which will allow mainly to increase the dosage scale-up.
