Each 21 day period will be considered a cycle. Disease status will be assessed with a Cancer Antigen (CA)-125 prior to the start of each new cycle with an assessment of measurable diseased by either CT or MRI every 6 weeks. Treatment will continue until disease progression, unacceptable toxicities, or the patient elects to withdraw from the study. All patients will be followed until disease progression or study withdraw. In addition, following disease progression, patients will be monitored for delayed toxicity and survival for a period of 5 years, unless consent is withdrawn.
