Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Bone marrow transplantation and peripheral stem cell transplantation may allow doctors to give higher doses of chemotherapy and kill more tumor cells.

PURPOSE: Phase I trial to study the effectiveness of combination chemotherapy with carboplatin and cyclophosphamide followed by bone marrow and peripheral stem cell transplantation in treating patients who have advanced ovarian epithelial cancer.

Description

OBJECTIVES: I. Determine the maximum tolerated dose of carboplatin when combined with cyclophosphamide as high-dose therapy followed by autologous bone marrow and peripheral blood stem cell rescue in patients with platinum sensitive ovarian epithelial carcinoma. II. Determine the efficacy of this regimen in these patients.

OUTLINE: This is a dose escalation study of carboplatin. Autologous bone marrow (ABM) is harvested on day -11, filgrastim (G-CSF) is administered subcutaneously (SC) on days -11 to -7, and autologous peripheral blood stem cells (PBSC) are harvested on day -6. Patients receive high dose chemotherapy comprising carboplatin IV over 15 minutes on days -5 and -4 and cyclophosphamide IV over 1 hour on days -3 and -2. PBSC are reinfused on day -1, ABM is reinfused on day 0, and G-CSF is administered SC beginning on day 7 and continuing until blood counts recover. Cohorts of 2-4 patients receive escalating doses of carboplatin until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which no more than 10% of patients experience dose-limiting toxicity. A minimum of 6 patients receive carboplatin at the MTD. Patients are followed at 1 month and then every 3 months for 5 years.

PROJECTED ACCRUAL: A minimum of 18 patients will be accrued for this study within 1 year.

Medical and Biotech [MESH] Definitions

Transfer of HEMATOPOIETIC STEM CELLS from BONE MARROW or BLOOD between individuals within the same species (TRANSPLANTATION, HOMOLOGOUS) or transfer within the same individual (TRANSPLANTATION, AUTOLOGOUS). Hematopoietic stem cell transplantation has been used as an alternative to BONE MARROW TRANSPLANTATION in the treatment of a variety of neoplasms.

Techniques for the removal of subpopulations of cells (usually residual tumor cells) from the bone marrow ex vivo before it is infused. The purging is achieved by a variety of agents including pharmacologic agents, biophysical agents (laser photoirradiation or radioisotopes) and immunologic agents. Bone marrow purging is used in both autologous and allogeneic BONE MARROW TRANSPLANTATION.

A cell-separation technique where magnetizable microspheres or beads are first coated with monoclonal antibody, allowed to search and bind to target cells, and are then selectively removed when passed through a magnetic field. Among other applications, the technique is commonly used to remove tumor cells from the marrow (BONE MARROW PURGING) of patients who are to undergo autologous bone marrow transplantation.

Transplantation of stem cells collected from the peripheral blood. It is a less invasive alternative to direct marrow harvesting of hematopoietic stem cells. Enrichment of stem cells in peripheral blood can be achieved by inducing mobilization of stem cells from the BONE MARROW.

Agents that destroy bone marrow activity. They are used to prepare patients for BONE MARROW TRANSPLANTATION or STEM CELL TRANSPLANTATION.
