Using the data from the GETMON ("Grupo Español de Trasplante de Medula Osea en Niños") we carried out a retrospective analysis of the results of allogeneic bone marrow transplantation (alloBMT) compared to autologous bone marrow transplantation (ABMT) in 113 paediatric patients with acute lymphoblastic leukaemia (ALL) in second remission. Transplants were performed by the following centers, from April 1983 to December 1991: H. Vall d'Hebrón and H. Sant Pau from Barcelona, H. Ramón y Cajal and H. Niño Jesús from Madrid and H. Marqués de Valdecilla from Santander. ⋯ In our experience we observed a better DFS with alloBMT compared with ABMT, overcoat in early relapses, but without significant difference. A higher relapse rate in ABMT group is partially compensated by more early deaths in alloBMT offers a few survival possibilities in patients with medullary relapses whose first remission lasted less than 30 months.
