Immunotherapy involves taking medications that stimulate your immune system to destroy cancer cells. It can sometimes treat oral cancer that can’t be removed surgically or has returned.
The American Cancer Society estimates that
The main treatments for oral cancer are:
Immunotherapy is a rapidly developing type of cancer treatment. The Food and Drug Administration (FDA) has approved
Read on to learn more about how immunotherapy can help treat oral cancer.
Doctors can usually treat oral cancer contained in your mouth or surrounding area with a combination of surgery and radiation therapy.
Pembrolizumab and nivolumab
Your T cells are white blood cells that attack cancer cells and foreign cells. They contain “checkpoint” proteins on their surface that keep them from being too aggressive. Some cancer cells produce proteins that bind to these checkpoint proteins to turn them off, allowing the cancer cells to avoid detection.
Immune checkpoint inhibitors block this binding process so that your T cells stay activated.
More specifically, pembrolizumab and nivolumab are programmed cell death protein 1 (PD-1) inhibitors. PD-1 is a checkpoint protein on the surface of T-cells. Some cancer cells produce a protein called PD-L1, which can bind to
Other immunotherapy drugs
- anti-EGFR monoclonal antibody
- anti-OX40 antibody
How effective is immunotherapy at treating oral cancer?
- pembrolizumab alone
- pembrolizumab with chemotherapy
- cetuximab with chemotherapy
The researchers concluded that pembrolizumab plus chemotherapy is an appropriate first-line treatment for recurrent or metastatic head and neck cancer. Pembrolizumab by itself was effective for treating PD-L1-positive recurrent or metastatic head and neck cancer.
Side effects of PD1 inhibitors include:
Rare but serious side effects include:
- infusion reactions, which can cause:
- trouble breathing
- facial flushing
- itchy skin
- autoimmune reactions, which can cause life threatening problems with your liver, lungs, or other organs
You’ll receive immunotherapy at a doctor’s office, clinic, or hospital.
Healthcare professionals administer nivolumab through an IV (intravenous) infusion every
They administer pembrolizumab with or without chemotherapy as an IV infusion every 3–6 weeks.
You’ll likely be able to go home shortly after your appointment unless you develop a side effect that requires further treatment.
Other treatment options for oral cancer include:
- Surgery: Surgery involves removing the tumor and tissue around it. Your doctor may combine this with radiation therapy.
- Radiation therapy: Radiation therapy uses high-energy waves to destroy cancer cells.
- Chemotherapy: These medications destroy cancer cells and other cells in your body that replicate quickly.
- Targeted therapy: Targeted medications specifically attack cancer cells. They tend to cause fewer side effects than chemotherapy.
Here are some frequently asked questions people have about immunotherapy.
What is the cure rate for most mouth cancers?
Your outlook with oral cancer depends on where the cancer develops. The 5-year relative survival for lip cancer is
The 5-year relative survival rate measures how many people with the cancer are alive 5 years later compared to people without the cancer.
Which cancers are most successfully treated with immunotherapy?
Immunotherapy is a relatively new treatment option still under investigation for treating many different types of cancer. Some of the most studied cancers include:
Is pembrolizumab (Keytruda) FDA-approved to treat oral cancer?
Doctors use immunotherapy to treat oral cancers that they can’t surgically remove or that have spread to other locations or returned after treatment. Researchers are still investigating how best to use immunotherapy to treat oral cancer.
