Chemotherapy for Thyroid Cancer
- How Chemotherapy Is Administered
Chemotherapy drugs are generally administered in three ways:
- By mouth in the form of a pill you swallow
- By injection
- Locally (directly to the tumor site)
Injection methods include:
- Intra-arterial (IA): into an artery
- Intramuscular (IM): into a muscle
- Intravenous (IV): into a vein
- Subcutaneous (SubQ): into the skin
Local/direct methods include:
- Intracavitary: in the cavity (or space) where your tumor had been prior to surgery
- Interstitial: into body tissue
- Intraperitoneal: into your abdomen or peritoneal cavity (intestines, liver, stomach, ovaries)
- Intrathecal: into the space between the meninges
- Intratumoral: into the tumor
- Intraventicular: into a ventricle
- Convection-enhanced delivery: into your tumor using gravity or controlled flow
Chemotherapy is a form of cancer treatment where high-powered medications are used to kill cancer cells. It’s a systemic approach to cancer treatment, where drugs are delivered through your bloodstream, targeting cancer cells throughout your body.

How Chemotherapy Is Used to Treat Cancer
Thyroid cancer is infrequently treated with chemotherapy. However, your physician team may recommend chemotherapy in addition to or instead of other treatments for:
- Anaplastic thyroid cancer
- Thyroid cancers that have spread (metastasized)
Chemotherapy is a form of cancer treatment where drugs are injected, given orally or through an IV, to keep your cancer from spreading. Often chemotherapy drugs are used in combination to attack cancer cells. It’s usually given in cycles over several months.
Chemotherapy is used in some cases:
- To kill any remaining cancer cells after surgery or radiation therapy; this kind of chemotherapy is called adjuvant chemotherapy
- To shrink the size of your tumor before surgery or radiation therapy; this kind of chemotherapy is called neoadjuvant therapy
- To treat recurrent cancer (cancer that has returned)
- As a palliative — to relieve the symptoms caused by cancer, such as bone pain
There are a wide variety of chemotherapy drugs available to treat cancer. At Scott & White, we use all the standard chemotherapies.
