Glioblastoma is the most common and aggressive type of primary tumors in the adult brain, and also represents a grade IV glioma. The glial cells are those that form part of support and protection for the nerve cells in the brain, and this cancer originates from these. Although the exact causes of glioblastoma are still yet to be known, several genetic and environmental causes are believed to induce them. This disease has attached some risk factors, such as the age factor, radiation exposure, and the family history factor in brain tumors. Depending upon its location, glioblastoma is often symptomatic though the most classic presentation is a chronic headache with concurrent seizures, cognitive alterations, nausea or vomiting and sometimes neurological deficits like weakness or difficulty with speech. Typically, these symptoms evolve into increased intracranial pressure resulting from rapid growth within the tumor. Diagnoses are mainly by radiologic methods, including MRI and CT scans, and then it is confirmed by biopsy. The most common treatments used are surgery to remove the mass of the tumor, radiation therapy, and chemotherapy with temozolomide. Glioblastoma often receives aggressive therapy. However, the prognosis is very poor with only a median survival rate for roughly 15 months. Researchers continue to search for better therapies that would provoke better outcomes in the patient.
