Chemotherapy Plus Bone Marrow or Peripheral Stem Cell Transplantation in Treating Patients With Recurrent or Refractory Solid Tumors
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with bone marrow or peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells.
PURPOSE: Phase I trial to study the effectiveness of melphalan and thiotepa plus bone marrow or peripheral stem cell transplantation in treating patients who have recurrent or refractory solid tumors.
Unspecified Adult Solid Tumor, Protocol Specific
Procedure: autologous bone marrow transplantation
Procedure: peripheral blood stem cell transplantation
|Study Design:||Primary Purpose: Treatment|
|Official Title:||High-Dose Consolidation With Escalating Doses of Melphalan and Thiotepa for Stage IV Breast Cancer|
|Study Start Date:||January 1999|
OBJECTIVES: I. Determine the maximum tolerated dose of melphalan and thiopeta in patients with recurrent or refractory solid tumors. II. Evaluate the overall survival and response rate in these patients.
OUTLINE: This is a dose escalation study. Patients receive cyclophosphamide IV over 1 hour on day 1 and paclitaxel IV over 4 or 24 hours on day 2, followed by daily filgrastim (G-CSF) subcutaneously beginning on day 3 and continuing through day 7 or until WBCs are greater than 100,000 cells/mm3. Peripheral blood stem cells (PBSC) or autologous bone marrow is collected on days 5-7. At 30-50 days following mobilization, patients receive melphalan IV over 15-60 minutes on days -5 and -4 and thiotepa IV over 2 hours on days -3 and -2, followed by autologous bone marrow transplantation or PBSC infusion on day 0. Sequential dose escalation of melphalan is followed by sequential dose escalation of thiotepa. Dose escalation in cohorts of 5 patients each continues until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 4, 3 of 7, 4 of 11, or 5 of 15 patients experience dose limiting toxicity. Patients are followed at 60 days and at 12 months.
PROJECTED ACCRUAL: A total of 40 patients will be accrued for this study within 4 years.
