Epithelial ovarian cancer (EOC) is the leading cause of gynecological cancer deaths, although it accounts for only about one-quarter of all gynecological malignancies (1, 2). A woman’s lifetime risk of ovarian cancer is about 1 in 70. In the year 2004, the American Cancer Society estimated that 25,580 women would be diagnosed with ovarian cancer in the United States, and that 16,090 would die of this disease (3).
