ABMT for children AML: Italian experience. GITMO-AIEOP Groups.
We report data from an Italian survey on ABMT in 93 AML children less than 14 years in 1st or 2nd remission performed in 15 Centers. Different conditioning regimens have been employed: BAVC, an original schedule of chemotherapy; TBI plus Cy and/or other drugs (TBI + CHT); other high dose chemotherapy schedules (HD CHT). 62 patients have been transplanted in 1st CR; 38 have been conditioned with BAVC, 16 with TBI + CHT and 8 with HD CHT. Relapses were 21 in the BAVC group (DFS = 35% at 66 months), 5 in the TBI group (DFS = 61% at 48 months) and 5 in the HD CHT group; overall DFS is 39% at 66 months. 31 patients have been transplanted in 2nd CR; 14 were conditioned with BAVC and 16 with TBI + CHT; 6 patients relapsed in the first group, DFS is 56% at 50 months; in the second group 2 early deaths and 3 relapses occurred, DFS is 65% at 65 months. 1 patient in 2nd CR, conditioned with HD CHT, died during aplasia. Overall DFS is 59% at 65 months. Although no final conclusions concerning ABMT in AML children may be drawn from this retrospective study because of heterogeneity of population and methods, results obtained in 2nd CR are clearly better to those obtained with standard chemotherapy alone, confirming the role of ABMT in this high risk category of patients.
