OUTLINE: This is a randomized, multicenter study. Patients are stratified by participating center and disease state at reassessment laparotomy. Patients are randomized to one of two treatment arms. Arm I: Patients receive paclitaxel IV over 3 hours on day 1 and carboplatin IV continuously on days 1-5 every 3 weeks for a total of 6 courses. Arm II: Patients receive cyclophosphamide IV over 1 hour and mitoxantrone IV over 15 minutes on days -8, -6, and -4, and carboplatin IV continuously on days -8 through -4, followed by rescue with autologous bone marrow or peripheral blood stem cells on day 0. Quality of life is assessed at baseline, at 3 and 9 weeks after starting treatment, and every 3 months for an additional 5 assessments regardless of disease progression.
