ReviewTargeting epidermal growth factor receptor: novel therapeutics in the management of cancer.
Overexpression of epidermal growth factor receptor (EGFR) in epithelial tumors, including head and neck, lung, breast, colon and other solid tumors, has frequently been correlated with poor prognosis, thus stimulating efforts to develop new cancer therapies that target EGFR. Monoclonal antibodies and tyrosine kinase inhibitors specifically targeting EGFR are the most well-studied and hold substantial promise of success. Several compounds of monoclonal antibodies and tyrosine kinase inhibitors targeting EGFR have been studied and clinical trials are now underway to test the safety and efficacy of these targeting strategies in several human tumors. ⋯ EGFR targeted treatment by monoclonal antibodies and tyrosine kinase inhibitors have been proven to sensitize tumor cells to the effects of chemotherapy and radiation therapy. The synergistic activities and nonoverlapping toxicities of these compounds allow concomitant administration with cytotoxic therapy. Challenges of evaluating EGFR targeted agents exist in selecting the optimal dosages and determining long-term toxicity.
