Editorial: Brain tumour treatment: the concept of inter- and multidisciplinary treatment.

The treatment of brain tumors has improved in recent years. The principles of treatment are accurate diagnosis by imaging and neuropathology, treatment by neurosurgery, neurooncology, medical oncology, radiotherapy and optimal care and supportive strategies in a multidisciplinary setting. The development of multidisciplinary neurooncologic teams and of centers of excellence will further improve treatment quality and care. The multidisciplinary team is not confined to medical treatment alone, but needs the expertise of specially trained nurses, psychologists, occupational therapists, speech therapists and social workers to meet the needs of patients and carers.
