Correlação clínico-topográfica em glioblastomas multiformes nas síndromes motoras: significados fisiopatológicos

Abstract: The clinical-topographic findings lead to consider the infiltrative effects (broad lesions) are responsible for the motor impairment rather than compressive effects (located lesions).

“…Gliosarcomas are rare CNS primary tumors that occur in ~4% of all malignant gliomas and affect mainly adults (especially in the fifth and sixth decades of life) 34 and males (male:female frequency ratio of 1.8:1) 35 . The clinical course is frequently associated with a poor prognosis, including a survival of less than three months in more than half of the cases 36 (a faster evolution compared to that observed in the present study, in which the survival varied from three to eight months after diagnosis). GSM is indistinguishable from GBM when the diagnosis is only based on clinical and neuroimaging characteristics.…”

“…The pathophysiology of the neurological signs and symptoms of GSM has not yet been fully clarified, although the focal manifestations vary according to the site of the tumor (the most affected regions are supratentorial and in the left hemisphere, especially the frontal and temporal lobes) 36 . The general signs and symptoms are often characterized by changes in the level of consciousness, nausea, vomiting and headache (intracranial hypertension), reflecting the compressive aspect resulting from the rapid tumor growth; this may be associated with perilesional edema, as well as the toxic effects of tumor necrosis itself 36 .…”

“…Os glioblastomas representam mais de dois terços dos gliomas encontrados nesta casuística. Resultados semelhantes foram encontrados em outros estudos similares, fazendo com que seja imprescindível uma melhor compreensão de um tumor cuja mortalidade é tão alta [12][13][14][15] .…”

“…Não foi possível identificar o fator que levou a uma predileção dos GBM deste estudo pelo sexo masculino (69,1%), enquanto outros autores nacionais trazem essa predileção entre 55% e 66% 12,14,15 .…”

“…O prognóstico desse tumor é extremamente ruim devido a seu alto grau de malignidade em 50% dos casos 5,6 . Os pacientes apresentam sinais e sintomas focais ou gerais (cefaleia, náuseas ou vômitos e alterações do nível de consciência), dependendo do tamanho, da localização e da taxa de crescimento do tumor 7,8 . As manifestações clínicas causadas pela presença de um GBM devem-se predominantemente aos efeitos compressivos decorrentes do crescimento rápido do tumor e do edema peritumoral, atribuível a essa ação direta do PROGNÓSTICO FAVORÁVEL NO GLIOBLASTOMA tumor ou efeito tóxico de produtos necróticos liberados da massa tumoral [9][10][11] .…”
