Repeated Bone Marrow Transplantation in Treating Women With Advanced Breast Cancer
Recruitment status was Active, not recruiting
RATIONALE: Bone marrow transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells.
PURPOSE: Phase I/II trial to study the effectiveness of repeated use of high-dose chemotherapy plus bone marrow transplantation and samarium 153 in treating women who have stage IV breast cancer.
Drug: CAF regimen
Drug: doxorubicin hydrochloride
Procedure: peripheral blood stem cell transplantation
Radiation: samarium Sm 153 lexidronam pentasodium
|Study Design:||Primary Purpose: Treatment|
|Official Title:||Phase I/II Study of Samarium 153 as Part of a Double (Sequential) Autologous Bone Marrow Transplant (ABMT) for Patients With Stage IV Breast Cancer|
|Study Start Date:||March 1997|
OBJECTIVES: I. Determine the maximum tolerated dose (MTD) of samarium 153 used sequentially with autologous bone marrow transplantation for metastatic breast cancer. II. Determine the response rate, median duration of response, and overall survival of patients who respond to induction therapy followed by 2 cycles of high dose chemotherapy and stem cell support.
OUTLINE: This is a dose escalation study. Patients are first treated with salvage chemotherapy for no more than 4 cycles. At least a partial remission must be achieved. Peripheral blood stem cells (PBSC) are collected following the administration of filgrastim (granulocyte colony-stimulating factor; G-CSF). After recovery from the prior chemotherapy, high dose chemotherapy begins. Paclitaxel is administered as a 24 hour infusion on day -7. Melphalan IV is administered over 1 hour on days -6 and -5. PBSC are infused on day 0. A second regimen of high dose chemotherapy begins after at least 42 days posttransplant and as long as at least partial remission occurs after previous chemotherapy. Samarium 153 is administered on day -14. Cohorts of 3 patients each are treated at each dose level until the maximum tolerated dose is reached (defined as dose at which the dose limiting toxicity occurs in 3 or more of 6 patients). Cyclophosphamide, thiotepa, and carboplatin are infused over 24 hours on days -7 through -4. PBSC are infused on day 0 followed by G-CSF IV. The phase II dose of samarium 153 is one dose level below the MTD determined in the Phase I portion of this study. Patients are followed until death.
PROJECTED ACCRUAL: At least 12 patients will be accrued for this study.
