Thyroid Cancer: Targeted Therapy
What is targeted therapy?
Targeted therapies are medicines that affect a cancer cell's ability to grow and to spread. They focus on, or target, changes found mainly on or in cancer cells, such as certain proteins or gene changes. This means they tend to have very different side effects than chemotherapy.
Tests can be done on your cancer cells to see if they have the changes that these medicines target. Many different medicines are used, and there are a lot of different targets these medicines act on.
When might targeted therapy be used for thyroid cancer?
Targeted therapy is mostly used to treat medullary thyroid cancers (MTCs) and anaplastic thyroid cancers. The usual iodine- and hormone-based treatments that work for other types of thyroid cancer don't often work for these cancers.
Papillary, follicular, and Hurthle thyroid cancers that don't respond to the usual treatments may be treated with targeted therapy, too.
How is targeted therapy given for thyroid cancer?
The targeted therapy medicines used for thyroid are all taken as pills or capsules. You will take them at home once or twice a day. Targeted therapy medicines include:
Even though they're pills, they're still strong medicines that can cause side effects.
What are common side effects of targeted therapy?
Some of the more common side effects of targeted therapy include:
Diarrhea, which may be caused by an inflamed colon (colitis)
High blood pressure
Severe tiredness (fatigue)
Skin problems, such as dryness, rash, blistering, or darkening skin
Problems with wound healing
Hand-foot syndrome (redness, pain, and swelling in hands or feet)
Muscle and joint pain
Most of these side effects go away or get better over time after treatment ends. There may be things you can do to help control some of them.
These medicines can also cause severe side effects such as infection, changes in heart rhythm, lung inflammation, or severe bleeding. But these are rare. Tell your healthcare providers about any side effects you have. They can help you cope with the side effects.
Your healthcare provider may do tests of your kidney, thyroid, liver, and other functions during targeted therapy treatment.
Working with your healthcare provider
It's important to know which medicines you're taking. Write down the names of your medicines. This includes prescription and over-the-counter medicines. Ask your healthcare team how they work and what side effects they might cause. Tell them about any herbs, vitamins, and supplements you take. Some of these might interact with your targeted therapy.
Talk with your healthcare providers about what symptoms to watch for and what to do if you have any. Ask them what changes you should call them about. For instance, some types of targeted therapy can cause rashes that might get worse if not treated right away. Know what number to call with questions. Is there a different number for evenings and weekends?
It may be helpful to keep a diary of your side effects. Write down any physical, thinking, and emotional changes. A written list will make it easier for you to remember your questions when you go to your appointments. It will also make it easier for you to work with your healthcare team to make a plan to manage your side effects.
