Autologous Bone Marrow Transplantation in Multiple Myeloma: A Single Centre Experience of 23 Patients

We report the complications and outcome of high-dose melphalan and TBI combined with ABMT used in the treatment of multiple myeloma at a single centre. Twenty-three patients, aged 65 years or less, who underwent the procedure are reviewed. All had chemosensitive disease. Response to ABMT assessed at 3 months showed 75% of evaluable patients to have further tumour cytoreduction of at least 50%, with 24% of patients who entered ABMT with residual disease eventually achieving CR. There was one toxic death. The overall survival is 60% and the progression-free survival is 49.8% at a median follow-up time of 17 months. Relapse or disease progression has occurred in 27% of patients, of whom half have died. No significant prognostic factors affecting survival were found although those patients with IgG myeloma had a better outcome. Patients transplanted in first plateau appeared to do significantly better if they had been resistant to their first-line chemotherapy but had then responded to further conventional chemotherapy (p = 0.029).
