About
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy and kill more tumor cells.
PURPOSE: Phase I trial to study the effectiveness of sequential chemotherapy followed by peripheral stem cell transplantation in treating patients with persistent or platinum refractory stage III or stage IV ovarian cancer.
Full description
OBJECTIVES: I. Establish the feasibility of treating patients with persistent or platinum refractory stage III or IV ovarian cancer with sequential high dose chemotherapy followed by peripheral blood stem cell rescue. II. Determine the maximum tolerated dose of thiotepa that can be given in such approach.
OUTLINE: This is a dose escalating study of thiotepa. Initial cytoreduction and mobilization of peripheral blood stem cells (PBSC) are conducted with FHCRC protocol 506.3 (cyclophosphamide and paclitaxel) or 506.3 (cyclophosphamide and etoposide). PBSC from syngeneic twins are collected according to FHCRC protocol 753.0. Patients then undergo leukapheresis. Patients with remaining bulky disease (greater than 2 cm) after cytoreduction/mobilization may undergo surgical debulking. High dose chemotherapy begins 30-40 days after the last chemotherapy in the cytoreduction/mobilization regimen. Patients receive mitoxantrone IV infusion over 15 minutes on days -7 and -5. Thiotepa IV is administered on days -4 and -3. Peripheral blood stem cell (PBSC) infusion occurs on day 0. 60-90 days later, melphalan IV is administered over 60 minutes on day -3. Patients undergo PBSC infusion on day 0. Patients are entered in cohorts of 3. In the absence of dose-limiting toxicity (DLT), subsequent cohorts of 3 patients each receive escalating doses of thiotepa on the same schedule. If DLT is observed in 2 of 3 patients, then the next cohort of patients each receive treatment at the next lower dose level. Once 12 patients are treated at a particular dose level, then this dose is declared the maximum tolerated dose. After engraftment following melphalan, patients receive oral tamoxifen twice a day for up to 5 years or until relapse. Patients are followed every 3 months for the first year, every 6 months for the next 4 years, then annually.
PROJECTED ACCRUAL: 20-30 patients will be accrued in 2 years.
