Chemotherapy for thyroid cancer

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

When you might have chemotherapy for thyroid cancer

Chemotherapy is not usually used to treat thyroid cancer. You might have this treatment for a type of thyroid cancer called anaplastic thyroid cancer.

You might also have chemotherapy as part of a clinical trial.

Your doctor will discuss chemotherapy with you if they think it can help you. They can explain how you have it and for how long.

Types of chemotherapy

The most common type of chemotherapy for thyroid cancer are:

  • doxorubicin (Adriamycin)
  • cisplatin

You may have a combination of these drugs.  Or you might have one of these drugs with another chemotherapy drug.

Into your bloodstream

You have the treatment through a drip into your arm or hand. 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.

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 things in to do. For example, newspapers, books or electronic devices can all help to pass the time. You can usually bring a friend or family member with you.

You have some types of chemotherapy over several days. You might be able to have some drugs through a small portable pump that 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.

Some hospitals may give certain chemotherapy treatments to you at home. Your doctor or nurse can tell you more about this.

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
  • diarrhoea or constipation
  • hair loss
Contact your doctor or nurse immediately if you have signs of infection. These include a temperature above 37.5C or below 36C, 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 a few days or so. Your treatment team can help to manage any side effects that you have.

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
  • have been prescribed anything by alternative or complementary therapy practitioners

It’s unclear how some nutritional or herbal supplements might interact with chemotherapy. They could be harmful.
