Targeted therapies for papillary and follicular thyroid cancer

The two main types of targeted therapy for thyroid cancer are sorafenib and lenvatinib. They interfere with the way cancer cells grow.

About targeted therapy for papillary and follicular thyroid cancer

Targeted therapies target something in or around the cancer cell that is helping it grow and survive. The 2 main targeted therapy drugs used to treat follicular or papillary thyroid cancer are:

They may be used if the cancer has come back, or has spread and is no longer responding to radioactive iodine treatment.

This information is about papillary and follicular thyroid cancer. We have more information about targeted therapy for medullary thyroid cancer and anaplastic thyroid cancer.

Sorafenib and lenvatinib

Sorafenib and lenvatinib are types of drugs called tyrosine kinase inhibitors (TKIs), or multi-kinase inhibitors. They work by blocking (inhibiting) signals in the cancer cells that make them grow and divide. They can help to shrink the cancer and control the growth, sometimes for a long time.

You take sorafenib as tablets you swallow twice a day. You take lenvatinib as capsules you swallow once a day. 

The side effects may include:

Your doctor or specialist nurse will give you more information about the drugs and the possible side effects. When you first start, you usually visit the hospital every 2 weeks. This is to check how you are managing the side effects. After this, the visits will be less often.

Other targeted therapies

There are other targeted therapy drugs that are used to treat thyroid cancer. These types of drugs only work if you have a certain gene change (mutation) in the cancer cells. For example, they may work if you had the NTRK, RET or the BRAF gene. Your cancer doctor may send some thyroid tissue from your biopsy or surgery to be checked for these changes.

Your cancer doctor will discuss with you if any of these drugs are suitable and available for you.

The language we use

We want everyone affected by cancer to feel our information is written for them.

We want our information to be as clear as possible. To do this, we try to:

  • use plain English
  • explain medical words
  • use short sentences
  • use illustrations to explain text
  • structure the information clearly
  • make sure important points are clear.

We use gender-inclusive language and talk to our readers as ‘you’ so that everyone feels included. Where clinically necessary we use the terms ‘men’ and ‘women’ or ‘male’ and ‘female’. For example, we do so when talking about parts of the body or mentioning statistics or research about who is affected.
