Chemotherapy treatment

Chemotherapy uses anti cancer (cytotoxic) drugs to destroy brain tumour cells. The drugs circulate throughout your body in the bloodstream.

It can be difficult to treat brain tumours with some chemotherapy drugs because the brain is protected by the blood brain barrier. This is a natural filter between the blood and the brain which protects the brain from harmful substances.

When you have chemotherapy

You might have chemotherapy:

  • after surgery for some types of brain tumour such as gliomas
  • with radiotherapy and for some months afterwards
  • for a brain tumour that has come back after treatment

How often you have chemotherapy

You usually have chemotherapy in cycles of treatment. This means that you have the drugs for a few days every few weeks. There is a time with no treatment when you recover from the side effects. 

How often you have treatment depends on the particular drug or drugs that you are having.

Types of chemotherapy

Common types of chemotherapy drugs for brain tumours include: 

  • temozolamide
  • procarbazine
  • carmustine (BCNU)
  • lomustine (CCNU)
  • vincristine
  • a combination of drugs called PCV

How you have chemotherapy

There are different ways of having chemotherapy for a brain or spinal cord tumour.

You might have it:

  • as a drip into your bloodstream (intravenously)
  • into your spine (intrathecal chemotherapy)
  • directly into your brain
  • as tablets or capsules that you swallow (oral chemotherapy)

Chemotherapy as a drip into your bloodstream (intravenously)

You have treatment through a thin short tube (a cannula) that goes into a vein in your arm each time you have treatment.

Or you might have treatment through a long line: a central line, a PICC line or a portacath. These are long plastic tubes that give the drug into a large vein in your chest. The tube stays in place throughout the course of treatment.

Chemotherapy into your brain

Chemotherapy implants (wafers)

Your surgeon might put chemotherapy drugs into the brain tissue as a wafer. The chemotherapy drug is inside a gel wafer, which slowly dissolves over 2 to 3 weeks.

As the gel wafer dissolves, the chemotherapy is slowly released into the brain tissue. One example is a Gliadel wafer that contains carmustine (BCNU).

Ommaya reservoir

During surgery, your treatment team might put a small plastic dome under the skin of your scalp. It's called a ventricular access device or an Ommaya reservoir. This is less common than chemotherapy wafers.

Your doctor or nurse gently puts a small needle through your skin into the reservoir. They then give the chemotherapy straight into the fluid filled spaces in your brain. So it goes straight into your cerebrospinal fluid (CSF). This bypasses the blood brain barrier, which means that doctors can give smaller doses of chemotherapy.

Chemotherapy as tablets or capsules

You must take tablets and capsules according to the instructions your doctor or pharmacist gives you.

Whether you have a full or empty stomach can affect how much of a drug gets into your bloodstream.

You should take the right dose, not more or less.

Talk to your specialist or advice line before you stop taking a cancer drug.

Where you have chemotherapy

You usually have treatment into your bloodstream at the cancer day clinic. You might sit in a chair for a few hours so it’s a good idea to take newspapers, books or electronic devices to help to pass the time. You can usually bring a friend or family member with you. 

For some types of chemotherapy, or if you have chemotherapy into your brain or spinal cord, you usually have to stay in a hospital ward. This could be overnight or for a couple of days.

Before you start chemotherapy

You need to have blood tests to make sure it’s safe to start treatment. You have these either a few days before or on the day you start treatment. You have blood tests before each round or cycle of treatment.

Side effects

The side effects vary from one person to another. It is difficult to predict how you will feel and what side effects you will have.

Common side effects of chemotherapy include feeling sick and a drop in the levels of white blood cells causing an increased risk of infection.

When you go home

Chemotherapy for a brain tumour can be difficult to cope with. Tell your doctor or nurse about any problems or side effects that you have. The nurse will give you telephone numbers to call if you have any problems at home.

For support and information, you can call the Cancer Research UK information nurses on freephone 0808 800 4040, from 9am to 5pm, Monday to Friday. They can give advice about who can help you and what kind of support is available
