Chemotherapy for brain cancer
Chemotherapy is the use of drugs to treat cancer. The drugs travel through the bloodstream and damage or destroy rapidly dividing cells (cells that grow quickly) such as cancer cells, while causing the least possible damage to healthy cells.
You may have chemotherapy after surgery and possibly with radiation therapy (chemoradiation).

The blood-brain barrier
The brain has a protection system known as the blood–brain barrier, which helps protect the brain from substances in the blood, such as germs or chemicals, that may injure the brain. Only certain types of chemotherapy drugs can get through this barrier.
How chemotherapy is given
You may be given chemotherapy as capsules or tablets that you swallow (orally), or as a liquid through a drip inserted into your vein (intravenously).
Temozolomide is the most commonly prescribed chemotherapy drug for the treatment of glioma brain tumours.
Temozolomide is given as a capsule that is taken at home. Each treatment session is usually followed by a rest period of a few weeks. You may have chemotherapy for up to six months.
Side effects of chemotherapy
There are many possible side effects of chemotherapy, depending on the type of drugs you are given. Side effects may include:
- nausea or vomiting
- tiredness, fatigue and lack of energy
- increased risk of infection
- loss of appetite
- mouth sores and ulcers
- diarrhoea or constipation
- skin rash
- breathlessness due to low levels of red blood cells (anaemia)
- low levels of platelets (thrombocytopenia), increasing the risk of abnormal bleeding
- damage to ovaries or testicles, which can make you unable to have children naturally (infertile)
- reduction in the production of blood cells in the bone marrow; you may need to have their blood levels monitored regularly through regular blood tests.
It is rare to lose all your hair with the chemotherapy drugs used to treat brain and spinal cord tumours, although in some cases your hair may become thinner or patchy.
