Astrocytoma

(Brain Tumor; Glioma)

Definition

Astrocytoma IDH mutated is a type of brain tumor. An astrocytoma is a type of the larger group of brain tumors called gliomas. Astrocytoma IDH mutated is a tumor whose cells have a mutation in the IDH1 or IDH2 genes.

Causes

Cancer is when cells in the body split without control or order. These cells go on to form a growth or tumor. The term cancer refers to harmful growths. These growths harm nearby tissues. They also spread throughout the brain. It is not clear exactly what causes these problems.

Risk Factors

A person's chances of an astrocytoma IDH mutated could be higher due to:

  • Age—it is most common in those aged 30-64 years old
  • Having radiation to the head in the past
  • Rare diseases passed from parents to children such as Li-Fraumeni syndrome, or neurofibromatosis type 1 or type 2

Symptoms

Tumor growth can make pressure in the brain higher. This may lead to:

  • Headaches
  • Double vision
  • Nausea and vomiting

Problems depend on where the tumor is:

  • Frontal lobe—Changes in mood and personality, weak muscles on one side of the body
  • Temporal lobe—Problems with coordination, speech, and memory
  • Parietal lobe—Problems with touch, writing, or fine motor skills
  • Occipital lobe—Vision problems and hallucinations

Diagnosis

The doctor will ask about symptoms and health history. The answers and a physical exam may raise concern about an astrocytoma.

The doctor may also want to do:

  • Imaging tests such as:
  • Biopsy/craniotomy—a sample of brain tissue is taken and tests are done on it

Treatment

The location, size, and grade of the tumor will guide treatment. It may include:

Prevention

There is no way to prevent an astrocytoma IDH mutated since the cause is unknown.

Grading

Astrocytoma IDH mutated are graded from 2 to 4. These grades provide information on how aggressive the tumor is. Grade 4 is more aggressive and can spread to other parts of the brain and spinal cord.
