The GIMEMA ALL 0183 trial: analysis of 10-year follow-up. GIMEMA Cooperative Group, Italy.
We report the 10-year follow-up of the GIMEMA ALL 0183 trial. From 1983 to 1987, 358 adults with acute lymphoblastic leukaemia (ALL) were entered into this trial, which included a mild induction, an early intensive consolidation, a post-consolidation phase randomized in conventional maintenance (arm A) and in more intensive regimen (arm B). CNS prophylaxis did not include CNS irradiation. The overall complete remission (CR) rate was 79.3% (284/358); 212 patient were randomized (110 in arm A and 102 in arm B). The median overall CR duration was 20 months and the median overall survival (OS) 21 months; both curves reach a plateau after 6 years; at 10 years 25% of patients were projected to be in long-term remission and survivors. The median disease-free survival (DFS) was 17 months, at 10 years 27% and 28% of patients were DFSs in arm A and in arm B respectively. In multivariate analysis age, WBC count and L2 FAB subtype were found to significantly influence OS and DFS. With regard to our previous report OS appears to linearly correlate with initial WBC count and age (P = 0.0002 and P = 0.042 respectively). 195 (68.7%) patients relapsed (only 25 had isolated CNS). The overall second CR rate was 56.5%; 23 patients underwent transplantation (12 BMT and 11 ABMT). Post-relapse survival was found to be influenced by the duration of first CR.
