OUTLINE: Patients receive cisplatin IV over 30 minutes followed by irinotecan IV over 90 minutes. Treatment is administered weekly for 4 weeks (days 1, 8, 15, and 22) followed by 2 weeks of rest. Patients receive at least 3 courses (18 weeks) of therapy in the absence of disease progression or unacceptable toxicity. If patients demonstrate complete response to treatment, they are encouraged to undergo second-look laparoscopy or laparotomy. Quality of life is assessed before treatment, after the first course, and then after every 2 courses of therapy. Patients are followed 30 days after the last treatment and then for survival.
