Cetuximab
Pronunciation
Definition 1
A drug used to treat certain types of head and neck cancer, and a certain type of colorectal cancer that has spread to other parts of the body. It is also being studied in the treatment of other types of cancer. Cetuximab binds to a protein called epidermal growth factor receptor (EGFR), which is on the surface of some types of cancer cells. This may stop cancer cells from growing. Cetuximab is a type of monoclonal antibody. Also called Erbitux. (NCI Dictionary)
Definition 2
A recombinant, chimeric monoclonal antibody directed against the epidermal growth factor (EGFR) with antineoplastic activity. Cetuximab binds to the extracellular domain of the EGFR, thereby preventing the activation and subsequent dimerization of the receptor; the decrease in receptor activation and dimerization may result in an inhibition in signal transduction and anti-proliferative effects. This agent may inhibit EGFR-dependent primary tumor growth and metastasis. EGFR is overexpressed on the cell surfaces of various solid tumors. (NCI Thesaurus)
Definition 3
A monoclonal antibody used to treat certain types of head and neck cancer, and colorectal cancer that has spread to other parts of the body. It is also being studied in the treatment of other types of cancer. Monoclonal antibodies are made in the laboratory and can locate and bind to cancer cells. Erbitux binds to the epidermal growth factor receptor (EGFR), which is found on the surface of some types of cancer cells. (NCI Dictionary)
