Cetuximab, its clinical use and future perspectives.
Increase in the expression of epidermal growth factor receptors (EGFRs) has been observed in many tumours. EGFR overexpression usually correlates with a more advanced stage of the disease, a poorer prognosis and a worse chemotherapy response. For all the aforementioned reasons, EGFR inhibition can be considered an attractive approach in cancer treatment. One strategy has been extracellular domain receptor inhibition, using monoclonal antibodies. In this review, we summarize the current status as well as what is likely to be the future use of monoclonal antibodies directed against EGFR. We have focussed on cetuximab being the most developed one. It has been mainly studied in colorectal cancer, and the major portion of this review will focus on all the research that has been carried out on this tumour. Clinical development of cetuximab is also important in head and neck cancer and in lung cancer. Interesting studies have been carried out in pancreatic, gastric, oesophageal and ovarian tumours, as well as in malignant gliomas.
