Glioblastoma multiforme is a malignant brain tumor that carries an extremely poor prognosis.

Signs and symptoms

• Symptoms of increased Intracranial pressure including headache, pappiledema, nausea or vomiting, and diplopia.

Treatment

Currently, most patients with Glioblastoma multiforme are initially treated with maximal surgical removal of the tumor, which is then followed by radiotherapy and Chemotherapy, most often with Temozolomide, a chemotheraputic agent that has been shown to have activity against glioblastoma multiforme. Radiosurgery is being investigated in the treatmet glioblastoma multiforme.
