Glioblastoma may be treated both medically within our Brain Tumor & Neuro Oncology Program and surgically at our Upstate Brain and Spine Center.

About Glioblastoma

Definition

Glioblastoma IDH wild type (GBM IDHwt) is the most common infiltrating glioma. Glioma is a type of brain cancer whose cells soak into normal brain tissue.

Causes

Cancer is when cells grow out of control. The cells can form a clump of tissue called a growth or tumor. Cancer cells can invade nearby tissues. It can then spread to other parts of the body. It is not clear what causes this.

Risk Factors

The chances of GBM are higher for people who:

  • Are aged 50 years or more
  • Are White, Hispanic, or Asian
  • Have rare inherited diseases such as Li-Fraumeni syndrome or neurofibromatosis type 1
  • Were exposed to radiation to the head
  • Were possibly exposed to some types of harmful chemicals

Symptoms

Symptoms depend on the tumor's size and where it is. They may include:

  • Symptoms caused by growing pressure to the brain:
    • Headaches
    • Nausea or vomiting
    • Double vision
    • Sleepiness
  • Symptoms caused by where the tumor is:
    • Weakness
    • Numbness
    • Problems speaking
    • Problems thinking
    • Vision problems
    • Problems walking
    • Seizures

Diagnosis

The doctor will ask about symptoms and health history. A doctor may also want to do:

  • Imaging tests such as:
  • EEG—to test the electrical activity of the brain.
  • Biopsy or resection—some of the tumor is removed and tested. This can help doctors learn more about it and make a treatment plan.
  • Lumbar puncture—to test the fluid that surrounds the brain and spinal cord. This is not done as often for GBM IDHwt.

Treatment

Surgery is often done to confirm a diagnosis and to remove as much of the tumor as possible. All of the tumor cannot be taken out with surgery. Other ways to manage GBM IDHwt are:

  • Radiation therapy—to shrink the tumor
  • Chemotherapy—to improve length and quality of life
  • Tumor treating fields

GBM is very hard to treat. It may come back after being removed. It often causes death. A person who has GBM IDHwt may be advised to find:

  • Support groups
  • Counseling
  • Someone to help with end of life planning
  • Hospice care

Prevention

GBM IDHwt cannot be prevented.
