The Neuro-Oncology Study Group (NOSG) at SENEC has commissioned the elaboration of the present document to the Neuro-Oncology Committee at Donostia University Hospital. It is intended to serve as a NOSG Consensus Guide and a proposed recommendation for the management of this pathological condition at all Spanish Hospitals, both public and private. Neuro-Oncology Committees must be established and active at all centres with a Neurosurgery Service, taking into account the specific diagnostic and therapeutic capacity available. The work presents an example of the constitution, functioning and experience of such a Committee, drawing on 8 years of multidisciplinary work with brain tumour patients.
