What was measured

Percentage of patients who were progression free at 3 years. The 3-year progression free rate was estimated using the Kaplan Meier method. Progression is assessed when one of the following occur: * reappearance of monoclonal protein by immunofixation, * Increase in serum monoclonal paraprotein to \>25% above the lowest response level, * Increase in urine M-protein to \> 25% above the lowest remission value for 24-hour excretion.

Groups in this outcome

Low-Dose Melphalan

Patients receive low-dose melphalan 20 mg/m\^2 IV over 15-30 minutes on day 1 or 0.12 mg/kg tablet orally once daily on days 1-7 and dexamethasone 40 mg orally on days 1-4 and 22-25. Treatment repeats every 6 weeks for 10 courses. (Study treatment beyond one year is not allowed.)

High-Dose Melphalan + Autologous HSC

Patients receive filgrastim (G-CSF) 10 mg/kg/day on days -7 to -3 and undergo autologous hematopoietic stem cell (HSC) collection. Patients receive high-dose melphalan 140 mg/m\^2 IV for low risk or 200 mg/m\^2 IV for high risk patients over 1 hour on days -2 and -1 and undergo autologous HSC transplantation on day 0.
