Evaluacion cuidadosa en cada caso en particular, aumentar el indice de sospecha de los gliosarcomas y diagnostico diferencial ante los glioblastomas multiforme, la determinacion de la GPAF y Ki 67 es primordial en estos casos, asi como el grado de reseccion tumoral mayor, posibilita una mayor sobrevida en estos pacientes.
