Removal of right cerebral hemisphere for certain tumors with hemiplegia Dandy WE JAMA 90: , 1928 “In the gradual evolution of resections of frontal, temporal and occipital lobes for the cure or attempted cure of invasive and otherwise incurable cerebral tumors, it has been found that the right temporal lobe, either frontal lobe or either occipital lobe (the left posterior to the supramarginal gyrus) could be completely removed without apparent mental impairment”.

Goals of surgery for malignant gliomas 1. Providing diagnosis 2. Relieving symptomatic mass effect 3. Improving or manteining the KPS and QOL 4. “Setting up” postoperative externally delivered therapies 5. Prolonging survival through cytoreduction 6. Applying locally-delivered therapies
