Bone Marrow or Peripheral Stem Cell Transplantation in Treating Patients With Breast Cancer
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with autologous bone marrow transplantation or peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells.
PURPOSE: Randomized phase III trial to compare bone marrow transplantation with peripheral stem cell transplantation following carboplatin in treating patients with breast cancer.
Procedure: autologous bone marrow transplantation
Procedure: peripheral blood stem cell transplantation
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: No masking
Primary Purpose: Treatment
|Official Title:||Randomized Phase III Trial of G-CSF Primed Autologous Bone Marrow Versus Peripheral Blood Progenitor Cells (PBPC) as Hematopoietic Support for High-Dose Cyclophosphamide, Thiotepa, and Carboplatin (CTCb) Therapy in Poor Prognosis Breast Cancer|
|Study Start Date:||June 1996|
|Study Completion Date:||December 2003|
|Primary Completion Date:||January 2000 (Final data collection date for primary outcome measure)|
|Active Comparator: Peripheral Blood Progenitor Cells||Procedure: peripheral blood stem cell transplantation|
|Experimental: Autologous Bone Marrow Collection||Procedure: autologous bone marrow transplantation|
OBJECTIVES: I. Compare engraftment rates using G-CSF primed autologous bone marrow vs PBCP as hematopoietic support following high dose CTCb for patients with poor prognosis breast cancer. II. Compare the complications of these two methods of hematopoietic progenitor cell collections. III. Compare Stage IV patients with bone or bone marrow involvement (assigned to PBPC collections) with Stage IV patients randomized to PBPC collections relative to the number of leukaphereses needed to collect the required number of progenitor cells as well as assess engraftment rates between these two groups. IV. Assess the response to high dose CTCb in this group of patients.
OUTLINE: All patients will receive G-CSF priming therapy for 5 consecutive days. Patients will then be randomized into two treatment arms: Arm 1 consists of autologous PBPC collection Arm 2 consists of autologous bone marrow collection Within 2 weeks after progenitor cell collection, all patients will receive high dose CTCb therapy by continuous infusion for 5 days, followed by autologous hematopoietic progenitor cell infusion at least three days later. G-CSF will also be given after infusion until ANC count is over 5,000 or over 1,000 for 3 consecutive days.
PROJECTED ACCRUAL: 66 patients will be accrued at a rate of 24 per year.
