Glioblastoma Multiforme: An Overview

Glioblastoma multiforme (GBM) is the most common and deadliest type of brain cancer. It is a fast-growing tumor that forms in the brain and can spread to other parts of the central nervous system. GBM is often diagnosed in people over the age of 50, and it is more common in men than women.

Symptoms of Glioblastoma Multiforme

The symptoms of GBM can vary depending on the location of the tumor. Some common symptoms include:

  • Headaches
  • Seizures
  • Nausea and vomiting
  • Vision problems
  • Speech problems
  • Weakness or numbness on one side of the body
  • Difficulty with balance or coordination
  • Changes in personality or behavior

Diagnosis of Glioblastoma Multiforme

GBM is diagnosed through a combination of imaging tests, such as MRI and CT scans, and a biopsy. A biopsy is a procedure in which a small sample of tissue is removed from the tumor and examined under a microscope.

Treatment of Glioblastoma Multiforme

There is no cure for GBM, but treatment can help to improve symptoms and extend life. Treatment options include surgery, radiation therapy, and chemotherapy.

  • Surgery: Surgery is the primary treatment for GBM. The goal of surgery is to remove as much of the tumor as possible. However, it is often difficult to remove all of the tumor because it can be located in a critical area of the brain.
  • Radiation therapy: Radiation therapy uses high-energy rays to kill cancer cells. Radiation therapy can be given before or after surgery to help shrink the tumor or to prevent it from coming back.
  • Chemotherapy: Chemotherapy uses drugs to kill cancer cells. Chemotherapy can be given orally or intravenously.

Prognosis of Glioblastoma Multiforme

The prognosis for GBM is poor. The average survival time is less than 15 months. However, some patients with GBM may live for several years, depending on the location and size of the tumor and the patient’s overall health.

Research on Glioblastoma Multiforme

There is a great deal of research being done to find new and more effective treatments for GBM. Some promising new treatments include:

  • Targeted therapy: Targeted therapy is a type of treatment that uses drugs to block the growth of cancer cells. Targeted therapy drugs are designed to target specific molecules that are involved in the growth of cancer cells.
  • Immunotherapy: Immunotherapy is a type of treatment that uses the patient’s own immune system to fight cancer. Immunotherapy drugs are designed to help the immune system recognize and kill cancer cells.
  • Gene therapy: Gene therapy is a type of treatment that uses genes to treat cancer. Gene therapy drugs are designed to replace or repair damaged genes in cancer cells.

These are just a few of the promising new treatments that are being investigated for GBM. With continued research, it is hoped that new and more effective treatments will be found to help patients with this devastating disease.

Additional Information on Glioblastoma Multiforme

Causes of Glioblastoma Multiforme

The exact cause of GBM is unknown, but there are a number of risk factors that have been identified, including:

  • Age: GBM is more common in people over the age of 50.
  • Gender: GBM is more common in men than women.
  • Race: GBM is more common in whites than in blacks or Hispanics.
  • Family history: People with a family history of GBM are at an increased risk of developing the disease.
  • Exposure to radiation: People who have been exposed to radiation, such as from a nuclear accident or from medical treatments, are at an increased risk of developing GBM.

Complications of Glioblastoma Multiforme

GBM can lead to a number of complications, including:

  • Increased intracranial pressure: GBM can cause increased pressure in the skull, which can lead to headaches, nausea, vomiting, and seizures.
  • Hydrocephalus: GBM can block the flow of cerebrospinal fluid, which can lead to hydrocephalus, a condition in which the brain becomes enlarged.
  • Infections: GBM can weaken the immune system, which can make patients more susceptible to infections.
  • Blood clots: GBM can increase the risk of blood clots, such as deep vein thrombosis and pulmonary embolism.

Support for Patients with Glioblastoma Multiforme

There are a number of organizations that provide support for patients with GBM and their families. These organizations can provide information about the disease, treatment options, and financial assistance. Some of these organizations include:

  • The American Brain Tumor Association
  • The National Brain Tumor Society
  • The Children’s Brain Tumor Foundation
  • The Musella Foundation for Brain Tumor Research & Information


GBM is a devastating disease, but there is hope for patients with this diagnosis. With continued research, new and more effective treatments are being developed that are helping to improve the outlook for patients with GBM.
