    Os astrocitomas e oligodendrogliomas supratentoriais dos adultos sĂŁo tumores infrequentes. Analisamos retrospectivamente 23 pacientes com este tipo de neoplasia que foram operados entre 1986 e 2002. NĂŁo ocorreu nenhum Ăłbito no pĂłs-operatĂłrio. A sobrevida de 5 e 10 anos de todo o grupo foi 67 e 30% respectivamente, semelhante a outras experiĂȘncias. Em 14 pacientes obtivemos a remoção completa da lesĂŁo (60,8%) e em 9 (39,2%) ocorreu remoção parcial do tumor. No subgrupo da ressecção total do tumor, 89% sobreviveram 5 anos e 45% alcançaram 10 anos de sobrevida, em contraste com o subgrupo da remoção parcial em que somente 35% alcançaram os 5 anos de sobrevida e nenhum, 10 anos. Devido aos efeitos deletĂ©rios da radioterapia, nĂłs preferimos prescrevĂȘ-la apenas nos casos de recorrĂȘncia tumoral.<br>Low-grade supratentorial astrocytomas and oligodendrogliomas in adults are uncommon tumors of the central nervous system. We analyzed retrospectively 23 patients with this type of neoplasia, who were operated on between 1986 and 2002. There were no post-operative deaths. The survival rate at 5 and 10 years post-surgery for the entire sample was 67 and 30% respectively, similar to other outcomes. With 14 patients we achieved a complete removal of the lesion (60.8%) and with 9 (39.2%) partial removal of the tumor. In the sub-group which underwent total resection of the tumor, 89% survived 5 years and 45% attained 10 years of survival, in contrast with the sub-group that underwent partial removal in which only 35% attained 5 years of survival and none 10 years. Due to the deleterious effects of radiation therapy, we preferred to prescribe it only in cases of tumor recurrence
