Chemotherapy in Treating Patients With Recurrent, Metastatic, or Unresectable Ovarian, Fallopian Tube, or Peritoneal Cancer

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.

PURPOSE: Phase II trial to study the effectiveness of DX-8951f in treating patients who have recurrent, metastatic, or unresectable ovarian, fallopian tube, or peritoneal cancer.

OBJECTIVES: I. Determine the antitumor activity of DX-8951f in patients with recurrent, metastatic, or unresectable ovarian, tubal, or peritoneal carcinoma that is refractory to platinum, taxane, and topotecan. II. Evaluate the quantitative and qualitative toxic effects of this regimen in these patients. III. Evaluate the pharmacokinetics of this regimen in these patients.

OUTLINE: Patients are stratified by prior chemotherapy (minimally pretreated vs heavily pretreated). Patients receive intravenous DX-8951f over 30 minutes daily for 5 days. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients are followed every 3 months until death.

PROJECTED ACCRUAL: Approximately 37 patients will be accrued for this study.
