Epidermal growth factor receptor blockers for the treatment of ovarian cancer.

Ovarian cancer is the seventh most common cause of cancer death in women world-wide. Treatment consists of a combination of surgical debulking and platinum-based chemotherapy, alone or in combination with paclitaxel. Between 55% and 75% of women who respond to first-line therapy relapse within two years of completing treatment. Second-line chemotherapy is palliative and aims to reduce symptoms and prolong survival. Increased understanding about the molecular basis of ovarian cancer has led to the development of novel agents, such as epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors, and their effectiveness and toxicities in women with advanced ovarian cancer needs to be assessed.
