- Compare tumor cytoreduction achieved with VBMCP (vincristine/carmustine/melphalan/cyclophosphamide/prednisone) vs myeloablative melphalan (L-PAM) and total-body irradiation (TBI) with peripheral blood stem cell (PBSC) rescue in symptomatic myeloma patients with stable or responding disease after induction therapy with VAD (vincristine/doxorubicin/dexamethasone) followed by high dose cyclophosphamide plus filgrastim (G-CSF).
