At present, five-year survival for patients with early-stage disease ranges from 50 to 95 percent, while five-year survival for patients with advanced-stage disease is less than 25 percent. Several new drugs with significant activity in advanced-stage ovarian cancer offer hope for increased long-term survival in the future. This article reviews the current and experimental approaches to the treatment of all stages of ovarian cancer.
