low-grade glioma radiosurgery

low-grade gliomas (LGG), corresponding to WHO grades I and II, are an uncommon and heterogeneous group of tumors, which include several distinct histopathological types and subtypes. Because of their rarity, acquiring adequate data on which to base therapeutic decisions in such cases is difficult. According to present knowledge, it is reasonable to consider radiosurgery (in particular, Gamma Knife surgery) as a therapeutic option for some LGG. Nevertheless, there is a clear need for multicenter cooperation in order to augment the currently scanty data ¹⁾.
