Our 24/7 cancer helpline provides information and answers for people dealing with cancer. We can connect you with trained cancer information specialists who will answer questions about a cancer diagnosis and provide guidance and a compassionate ear.
Our highly trained specialists are available 24/7 via phone and on weekdays can assist through video calls and online chat. We connect patients, caregivers, and family members with essential services and resources at every step of their cancer journey. Ask us how you can get involved and support the fight against cancer. Some of the topics we can assist with include:
For medical questions, we encourage you to review our information with your doctor.
Immunotherapy can be used to treat some people with nasopharyngeal cancer (NPC).
Immunotherapy uses medicines to boost a person’s own immune system to find and destroy cancer cells more successfully.
Immunotherapy typically works on specific proteins in the immune system to increase the immune response. They have different, often less frequent, side effects from chemotherapy.
Some immunotherapy drugs, for example, monoclonal antibodies, work in more than one way to control cancer cells and may also be considered targeted drug therapy because they block a specific protein on the cancer cell to keep it from growing.
An important part of the immune system is its ability to keep itself from attacking normal cells in the body. To do this, it uses “checkpoints,” proteins on immune cells that need to be turned on (or off) to start an immune response. Cancer cells sometimes use these checkpoints to avoid being attacked by the immune system.
Drugs that target these checkpoints (called checkpoint inhibitors) can be used to treat some people with nasopharyngeal cancer.
Pembrolizumab (Keytruda), nivolumab (Opdivo), and toripalimab-tpzi (Loqtorzi) are drugs that target PD-1, a protein on T cells in the immune system. These drugs are called PD-1 inhibitors. PD-1 normally helps keep T cells from attacking other cells in the body. By blocking PD-1, these drugs boost the immune response against cancer cells. This may shrink some tumors or slow their growth.
These drugs can be used to treat advanced NPC, which is NPC cancer that has returned after treatment (recurrent), cannot be treated with surgery or radiation, or that has spread to other parts of the body (metastatic).
Chemotherapy in combination with a PD-1 inhibitor may be recommended for patients with newly diagnosed advanced NPC. A PD-1 inhibitor, given alone, may also be a therapy option for patients with advanced NPC that have progressed on chemotherapy.
Nivolumab is given as an intravenous (IV) infusion, typically every 2 or 4 weeks. Pembrolizumab is given as an IV infusion, typically every 3 or 6 weeks.
Toripalimab is given as an IV infusion, typically every 2 or 3 weeks.
Side effects of these drugs can include fatigue, cough, fever, nausea, diarrhea, cough, skin rash, loss of appetite, constipation, muscle and joint pain, and itching.
Other, more serious side effects that occur less often include:
It’s very important to report any new side effects during or after treatment with any of these drugs to your health care team right away. If you have any serious side effects, you might need to stop treatment and take high doses of steroids to suppress your immune system.
Our team is made up of doctors and oncology certified nurses with deep knowledge of cancer care as well as journalists, editors, and translators with extensive experience in medical writing.
