High‐dose melphalan with autologous stem cell support improves survival as part of initial therapy for myeloma. Previous studies of pre‐transplant induction regimens have compared paraprotein response rates but not long‐term outcomes after transplant. We reviewed the records of all patients with multiple myeloma who received an autologous stem cell transplant at the University of Pennsylvania Medical Center. We compared outcomes for 69 patients who received high‐dose melphalan conditioning after January 1, 2003 as part of initial therapy for myeloma, including 41 patients who received anthracycline‐based induction (VAD or DVD) and 28 patients who received thalidomide and dexamethasone induction. Baseline characteristics in these two groups were not different, though potentially clinically important differences were apparent in assignment to post‐transplant consolidation and maintenance therapy. Despite similar response rates during induction therapy, thalidomide and dexamethasone induction was associated with better progression‐free survival (hazard ratio 0.18, P = 0.011) after transplant. This effect persisted in multivariable regression models including baseline characteristics and post‐transplant treatment. Overall survival was not different between the two groups. These results suggest that the use of thalidomide during induction therapy may lead to improved long‐term outcomes after transplant. Future trials comparing induction therapies should examine progression‐free and overall survival after transplant to confirm this benefit. Am. J. Hematol., 2007. © 2007 Wiley‐Liss, Inc.
