Treatments for newly diagnosed glioblastoma

Finding out that you or a loved one has glioblastoma, or GBM, can be overwhelming. In the blink of an eye, you may feel that your life is turned upside down, and you have to make major treatment decisions. So, where do you start?

Things to consider when selecting treatments

Now is the time to speak to your doctor about the treatments available to you. Things to ask your doctor at this time include:

  • What are the treatment options in newly diagnosed GBM?

  • What are the expected results of these treatments?

  • What are the possible side effects?

  • Can this treatment be given close to home, or will I need to travel or relocate for a while?

  • What impact will treatment have on my ability to work or do normal activities?

Treatments for newly diagnosed GBM

By talking to your doctor and doing research on your own, you may learn that a diagnosis and treatment plan for newly diagnosed GBM can include:


Treatment options for newly diagnosed glioblastoma patients include surgery, radiation, chemo, and tumor treating fields

  • Surgery may be conducted first to remove as much of the tumor as possible and/or to take a sample of the tumor to make a diagnosis of the tumor type. Sometimes, people need to be awake for surgery so that surgeons can ask questions that help them protect important parts of the brain

    • During this time, your doctor may also test the tumor for tumor markers. Tumor markers may indicate what treatments may work better for you

  • Radiation may be used after surgery. A big machine is used to aim beams of high-energy X-rays, gamma rays, or protons at your head in order to kill the tumor cells inside. This outpatient treatment is usually done over the course of several weeks at a hospital or clinic

  • Chemotherapy refers to drugs that are used to kill cancer cells. You might be given chemotherapy in the form of a pill, an IV in the outpatient part of a hospital, or in a dissolving wafer that a surgeon implants in your brain

  • Tumor Treating Fields (TTFields), used together with the chemotherapy temozolomide (TMZ), are low-intensity electric fields that may slow or stop cancer cells from multiplying, and may cause them to die. TTFields are delivered through a wearable, portable, FDA-approved device called Optune
