In certain types of cancer, recent studies have allowed a better elucidation of some mechanisms involved in the development and progression of the disease. These mechanisms usually comprise the altered function of some proteins found on the surface or inside the tumor cells. Thus, these proteins became targets for the development of drugs to fight cancer. So these new drugs are being called molecular target drugs. Among the molecularly targeted drugs used in the treatment of cancer are tyrosine kinase inhibitors and monoclonal antibodies.

Molecular-targeted drugs have been used to treat cancer alone or in combination with chemotherapy. To learn more about molecular targeting drugs, see the Frequently Asked Questions – Molecular Targeting Drugs section.
