About chemotherapy

When, where and how you have chemotherapy for thyroid, and the possible side effects.

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

When you have it

You might have chemotherapy to treat advanced thyroid cancer, or cancer that has come back and is causing symptoms. It is not usually used as a first line treatment for thyroid cancer. 

You may have chemotherapy as part of a clinical trial.

Types of chemotherapy

The most common type of drugs for thyroid cancer are:

  • doxorubicin (Adriamycin)
  • cisplatin

Into your bloodstream

You have the treatment through a drip into your arm. A nurse puts a small tube (a cannula) into one of your veins and connects the drip to it.

You might need a central line. This is a long plastic tube that gives the drugs into a large vein, either in your chest or through a vein in your arm. It stays in while you’re having treatment, which may be for a few months.

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.

The pharmacists make chemotherapy for each person individually. They do this once your blood test results have come through. It’s worked out based on your weight, height and general health.

Where you have chemotherapy

You usually have treatment into your bloodstream at the cancer day clinic. You’ll 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 have some types of chemotherapy over several days. You might be able to have some drugs through a small portable pump you take home.

For some types of chemotherapy you have to stay in a hospital ward. This could be overnight or for a couple of days.

Side effects

Common chemotherapy side effects include:

  • feeling sick
  • loss of appetite
  • losing weight
  • feeling very tired
  • a lower resistance to infections
  • bleeding and bruising easily
Contact the doctor or nurse immediately if you have any signs of infection such as a temperature higher than 38C or generally feeling unwell. Infections can make you very unwell very quickly.

Side effects depend on:

  • which drugs you have
  • how much of each drug you have
  • how you react

Tell your treatment team about any side effects that you have.

Most side effects only last for the few days that you’re having the chemotherapy drugs. The team caring for you can help to reduce your side effects.

When you go home

Chemotherapy for thyroid cancer 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.

Dietary or herbal supplements and chemotherapy

Let your doctors know if you take any supplements or if you’re prescribed them by alternative or complementary therapy practitioners.

It’s uncertain how some nutritional or herbal supplements may interact with chemotherapy. Some could be harmful.
