Glioblastoma, also known as glioblastoma multiforme (GBM), is the most aggressive type of cancer that begins within the brain.[6] Initially, signs and symptoms of glioblastoma are nonspecific.[1] They may include headaches, personality changes, nausea and symptoms similar to those of a stroke.[1] Symptoms often worsen rapidly and may progress to unconsciousness.[2]

The cause of most cases of glioblastoma is not known.[2] Uncommon risk factors include genetic disorders, such as neurofibromatosis and Li–Fraumeni syndrome, and previous radiation therapy.[2][3] Glioblastomas represent 15% of all brain tumors.[1] They can either start from normal brain cells or develop from an existing low-grade astrocytoma.[7] The diagnosis typically is made by a combination of a CT scan, MRI scan and tissue biopsy.[1]

There is no known method of preventing the cancer.[3] Treatment usually involves surgery, after which chemotherapy and radiation therapy are used.[3] The medication temozolomide is frequently used as part of chemotherapy.[3][4] High-dose steroids may be used to help reduce swelling and decrease symptoms.[1] Greater surgical removal of the tumor is linked to longer survival.[8]

Despite maximum treatment, the cancer usually recurs.[3] The typical duration of survival following diagnosis is 12 to 15 months, with fewer than 3 to 7% of people surviving longer than five years.[2][5] Without treatment, survival is typically three months.[9] It is the most common cancer that begins within the brain and the second-most common brain tumor, after meningioma.[6][10] About 3 in 100,000 people develop the disease per year.[3] It most often begins around 64 years of age and occurs more commonly in males than females.[2][3] Immunotherapy is being studied as treatment for the cancer.[11]
