Combination Chemotherapy Followed by Peripheral Stem Cell Transplantation in Treating Women With Metastatic Breast Cancer

2014-08-27 03:57:31 | BioPortfolio

Summary

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 drugs and kill more tumor cells.

PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy followed by autologous peripheral stem cell transplantation in treating women who have metastatic breast cancer.

Description

OBJECTIVES: I. Evaluate the efficacy and toxicity of high dose topotecan with ifosfamide and etoposide followed by autologous peripheral blood stem cell rescue in women with metastatic breast cancer. II. Evaluate the response rates, progression free survival, engraftment, and nonrelapse related mortality in women treated with this regimen. III. Evaluate the pharmacokinetic profile of high dose topotecan with respect to the efficacy and toxicity of ifosfamide and etoposide in these women.

OUTLINE: Peripheral blood stem cells (PBSC) are harvested from the patient and stored. Patients receive ifosfamide IV over 2 hours and topotecan IV over 30 minutes on days -8 to -6, and etoposide IV daily over 24 hours on days -5 to -3. Autologous PBSC are reinfused on day 0. Patients are followed at 1, 3, 6, and 12 months, and then every 6 months thereafter.

PROJECTED ACCRUAL: A total of 20-40 patients will be accrued for this study over 2 years.

Medical and Biotech [MESH] Definitions

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.

A semisynthetic derivative of PODOPHYLLOTOXIN that exhibits antitumor activity. Etoposide inhibits DNA synthesis by forming a complex with topoisomerase II and DNA. This complex induces breaks in double stranded DNA and prevents repair by topoisomerase II binding. Accumulated breaks in DNA prevent entry into the mitotic phase of cell division, and lead to cell death. Etoposide acts primarily in the G2 and S phases of the cell cycle.

The release of stem cells from the bone marrow into the peripheral blood circulation for the purpose of leukapheresis, prior to stem cell transplantation. Hematopoietic growth factors or chemotherapeutic agents often are used to stimulate the mobilization.

Hematopoietic stem cells found in peripheral blood circulation.

Transplantation of STEM CELLS collected from the fetal blood remaining in the UMBILICAL CORD and the PLACENTA after delivery. Included are the HEMATOPOIETIC STEM CELLS.
