Correctly so. Regrettably, there probably is no new Drug X in the foreseeable future that will significantly reduce the death rate from ovarian cancer, be it Taxol®, taxotere, topotecan, gemcitabine, or liposomal doxorubicin—although each may result in significant responses and some prolongation of median survival. Epithelial ovarian cancer is a much more complex disease than anyone envisioned, when it was believed that extensive debulking surgery and the newest cytotoxic chemotherapy would radically reduce the death rate from ovarian cancer in the United States. Over 20 years after the first patient was treated with cisplatin for epithelial ovarian cancer, the annual death rate from ovarian cancer continued to increase. Just in the past decade, the number of women in the United States dying from ovarian cancer has increased 18% (Fig. 1) [1]. Although ovarian cancer is estimated to account for 26,700 cases and 14,800 deaths in 1996, it is a low-prevalence disease in comparison with breast cancer, which in 1996 is estimated to account for 185,700 cases and 44,560 deaths. Inexplicably, similar to breast cancer, the lifetime risk for ovarian cancer in the United States continues to increase. The most recent Surveillance, Epidemiology and End Results (SEER) calculations of lifetime risk for ovarian cancer are that 1 in 55 women will develop ovarian cancer over their lifetime, or 1.8%, up from the 1970 figures of 1 in 70, or 1.4% [2]. The 1.8% baseline lifetime risk for the general population is used to estimate the lifetime risk of known ovarian cancer risk factors (Table 1). Even utilizing what are now believed to be two of the most effective cytotoxic drugs against stage III and IV epithelial ovarian cancer, Taxol® and cisplatin, researchers reported that this resulted in an increase in the median disease-free survival of only five months, as compared with those women allocated to receive cisplatin and cyclophosphamide (median diseasefree survival of 18 and 12.9 months, respectively), felt then to be the standard therapy [3]. Patients treated with Taxol® and cisplatin survived a median of 14 months longer than those
