Abstract: RESUMO -Entre 1993 e 1999, foram analisados 35 pacientes submetidos a microcirurgia para remoção de tumor intramedular nos Serviços de Neurocirurgia do Hospital Nossa Senhora das Graças e do Hospital de Clínicas de Curitiba -PR. A população foi composta por 68,6% de pacientes do sexo masculino; a média de idade era de 32,9 anos. A localização tumoral mais frequente foi torácica em 40% dos casos, seguida pela região cervical e cervicotorácica em 25,7%. Ao exame neurológico realizado entre 6 a 12 meses do pós-op… Show more

“…The most important prognostic factors in determining postoperative survival are as follows: histological grade of the lesion, application of adjuvant radiotherapy and chemotherapy, localization, and preoperative neurological status. 12,15,20,28,30,34 We compared survival duration according to the histological grade in patients with anaplastic astrocytomas and GBMs (Fig. 5).…”

“…A avaliação da independência funcional pré-operatória é de extrema importância, visto que ela é fundamental para quantificar evolução e recuperação pós-operatória (KOERBEL et al, 2002 et al, 2003) O tratamento principal oferecido é a ressecção cirúrgica a fim de diminuir a pressão intracraniana e aliviar os sintomas neurológicos locais. Geralmente optase pela abordagem suboccipital da lesão com desvio ventricular permanente antes ou depois da ressecção do tumor.…”

“…4,7,11) However, astrocytoma is thought to imply worse functional prognosis than ependymoma, 3,5) because astrocytoma is less well circumscribed than ependymoma, including higher grade tumors, so total resection, which is the key for good prognosis, might be less feasible in patients with astrocytoma. 3,5,8,13) Some authors deny any correlation between radical resection and good postoperative outcome for low grade astrocytomas, 5,8) whereas others propose complete removal as a significant predicting factor for good prognosis. 2,10,13) These discrepancies may result from the inclusion of subependymoma (World Health Organization Atypidal Cervical Astrocytoma Manifesting as Occipitalgia grade I), which usually grows eccentrically within the spinal cord or exophytically, demonstrating sparse cellularity, clustering of cells, and dense fibrillary stroma.…”
