OBJECTIVES:

• Determine the maximum tolerated dose of topotecan with a fixed dose of etoposide phosphate as a component of a multicourse high dose chemotherapy regimen supported by peripheral blood stem cell transplantation in patients with persistent or recurrent ovarian epithelial, fallopian tube, or primary peritoneal cancer.
• Evaluate the response, time to progression, disease free survival, and overall survival in this patient population.

OUTLINE: This is a dose escalation study of topotecan.

All patients receive induction therapy consisting of 1 to 2 courses of mobilization therapy. Subcutaneous filgrastim (G-CSF) is given beginning 24 hours after induction dose. Following induction therapy, peripheral blood stem cells (PBSC) are harvested. After patients receive high dose paclitaxel and carboplatin chemotherapy, a portion of the PBSC are reinfused. When patients recover from the paclitaxel/carboplatin chemotherapy the administration of topotecan and etoposide phosphate begins. Topotecan is administered, as a 72 hour continuous infusion, according to a dose escalation schedule with a fixed dose of etoposide phosphate. A second portion of PBSC are reinfused after topotecan/etoposide phosphate chemotherapy. A course of thiotepa is given along with the final portion of PBSC after treatment with topotecan and etoposide phosphate.

Dose escalation of topotecan continues until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 or more patients experience dose limiting toxicity.

Patients are followed every 3 months for 1 year and every 4 months thereafter to determine progression free and overall survival.

PROJECTED ACCRUAL: Approximately 25-30 patients will be accrued for the phase I portion of this study, and 25 more patients will be accrued for the phase II portion.
