Targeted Therapy for Nasopharyngeal Cancer
As researchers have learned more about the changes in cells that cause cancer, they have been able to develop newer drugs that target these changes. These targeted drugs work differently from standard chemotherapy (chemo) drugs. They may work in some cases when chemo drugs don't, or they may help chemo drugs work better. Targeted drugs also often have different (and often less severe) side effects.
Cetuximab (Erbitux®)
Cetuximab is a monoclonal antibody (a man-made version of an immune system protein) that targets the epidermal growth factor receptor (EGFR). EGFR is a protein found on the surface of cells. It normally receives signals telling the cells to grow and divide. Nasopharyngeal cancer (NPC) cells sometimes have more than normal amounts of EGFR, which can help them grow faster. By blocking EGFR, cetuximab may slow or stop this growth.
The exact role of cetuximab in treating NPC is still being studied. It's most often used along with chemo and/or radiation in cases where the cancer has spread, come back, or continued to grow after initial chemo.
Cetuximab is given by IV infusion, usually once a week. Common side effects include:
- Skin problems, such as an itchy, acne-like rash on the face and chest, which can lead to infections
- Headache
- Tiredness and weakness
- Fever
- Diarrhea
- Nausea and vomiting
- Weight loss
A rare but serious side effect of cetuximab is an allergic reaction during the first infusion, which could cause breathing problems and low blood pressure. You will be given medicine before treatment to help prevent this.
