Brief Summary:
According to the O.M.S. Classification, grade 2 glioma is a pre-cancerous lesion, slowly progressive, infiltrating the central nervous system, mainly affecting young adults.
This surgery should nevertheless be conducted in awake condition to achieve two conflicting goals: get maximum brain tissue infiltrated by the tumor while preserving the integrity of functional structures. So awake after opening the skull, the patient undergoes a series of preoperative tests, administered by a speech therapist present in the operating room. This procedure allows the neurosurgeon to establish an individual functional brain mapping in real time, through the observation by the SLP of the patient's answers to direct electrical stimulation applied to the cortical and sub-cortical. This support is based on the extraordinary plasticity demonstrated by the brain in the presence of a slowly progressive lesion. To ensure the patient the highest achievable load should increase our understanding of brain function, including the neural bases of language, glioma grade 2 is predominantly localized functional area of language.
