In Terms of Survival , Is Autologous Peripheral Blood Stem-Cell or Bone Marrow Transplantation Better than Conventional Chemotherapy ?
After more than three decades of clinical trials testing various st and ard-dose chemotherapy regimens , the disease course of patients with multiple myeloma has not changed appreciably .
Conventional chemotherapy can provide effective palliation but is not curative ( 1 ) .

Comparison of interferon tolerance after autologous bone marrow or peripheral blood stem cell transplants for myeloma patients who have responded to induction therapy.
Interferon ( INF ) has been incorporated as part of maintenance therapy after high dose treatment in order to make remissions more durable . In this study we have compared peripheral blood stem cell transplant ( PBSCT ) versus autologous bone marrow transplant ( ABMT ) with respect to INF tolerance . Thirty nine PBSCT patients have been compared to 37 ABMT patients for INF tolerance . This is followed by a comparison of 15 PBSCT patients versus 21 ABMT patients for engraftment details , response and survival . INF was started at a median of 61 days in the PBSCT and 58 days in the ABMT patients ( P = NS ) . It was well tolerated in both groups without a significant difference in toxicity in the two arms . Engraftment was more rapid in the PBSCT patients with platelet recovery being significantly faster . Response and survival showed a favourable trend for ABMT patients though statistical significance was not reached and the cost of PBSCT was 12 % cheaper . We were thus able to conclude that PBSCT grafts were as durable and could tolerate INF just as well as ABMT .  Engraftment was more rapid and the procedure of PBSCT was also cheaper . Further studies with a larger group of patients will be required before comments on the efficacy of treatment can be made
