Lung cancer: Molecular scissors determine therapy effectiveness

In the past few years, a number of anti-cancer drugs have been developed which are directed selectively against specific key molecules of tumor cells. Among these is an antibody called cetuximab, which attaches to a protein molecule that is found in large amounts on the surface of many types of cancer cells. When this surface molecule, called epidermal growth factor receptor, or EGF-R for short, is blocked by cetuximab, the cancer cell receives less signals stimulating cell division.
