Peripheral Stem Cell Transplantation Plus Combination Chemotherapy in Treating Patients With Multiple Myeloma

Study Overview
=================
Brief 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 peripheral stem cell transplantation plus combination chemotherapy in treating patients who have multiple myeloma.

Detailed Description
-----------------
OBJECTIVES: I. Evaluate the complete and partial response in multiple myeloma patients receiving peripheral blood stem cells supported by high dose carmustine and melphalan followed by consolidation therapy with cyclophosphamide/dexamethasone/etoposide/cisplatin (DCEP) and paclitaxel/cisplatin. II. Evaluate the incidence of early death in comparison with historical data in this patient population. III. Evaluate the feasibility of chemotherapy with DCEP and paclitaxel/cisplatin following autotransplantation in these patients. OUTLINE: Patients receive carmustine IV over 2 hours on day -2, followed by melphalan IV over 20 minutes on day -1. Patients receive intravenous CD34 peripheral blood stem cells on day 0. At 3 months and 9 months, patients with adequate hematologic counts receive cyclophosphamide IV, oral dexamethasone, etoposide IV, and cisplatin IV for 4 days. At 6 and 12 months after autotransplantation, patients with adequate peripheral blood counts and creatinine receive oral dexamethasone on days 1-4, paclitaxel IV over 6 hours on day 2, and cisplatin IV over 24 hours on day 3. Patients are followed every 6 weeks to 3 months until death. PROJECTED ACCRUAL: Approximately 24-63 patients will be accrued for this study within 2.5 years.
