The majority of patients with ovarian cancer, especially those who present with stages IIIC and IV, will relapse soon after completion of platinum-based induction treatment. It is imperative to find ways to improve and/or enhance the efficacy of induction and to prolong the duration of the first remission. The epidermal growth factor receptor (EGFR) family has been exploited, and currently, three agents that directly target this group of receptors are in use in the treatment of colorectal, non-small-cell lung and breast cancers. EGFR and HER2/neu are overexpressed in a significant percentage of epithelial ovarian cancers. Thus, it would be reasonable to explore directly targeted therapy in ovarian cancer. Numerous investigational trials involving a variety of EGFR inhibitors in ovarian cancer are ongoing. Our institution has an active phase II clinical study that seeks to define the role of erlotinib (Tarceva) in potentiating first-line chemotherapy, and to determine whether the drug offers a significant contribution as maintenance therapy. It is hoped that data from these and other studies will help investigators to understand more clearly the biology of ovarian cancer and to delineate the role of EGFR inhibitors in the management of ovarian cancer.
