Abstract

OBJECTIVE:

The purpose of this study was to re-evaluate post-remission therapy outcomes after first remission according to years of patient enrollment in patients with core binding factor acute myeloid leukaemia.

METHODS:

We conducted a retrospective study on 138 patients aged less than 60 years diagnosed with core binding factor acute myeloid leukaemia between 1994 and 2006, comparing allogeneic stem cell transplantation and high-dose cytarabine chemotherapy as post-remission treatment options after the first remission.

RESULTS:

The 5-year probabilities of disease-free survival and overall survival were not different between allogeneic stem cell transplantation and high-dose cytarabine groups. However, 3-year probabilities of disease-free survival (86.7% vs. 67.0%) and overall survival (90.0% vs. 67.3%) showed a trend towards improvement in the allogeneic stem cell transplantation group compared with the high-dose cytarabine group in cohort after 2003 (2003-2006), whereas outcomes were not different in cohort before 2003 (1994-2002). Especially, 3-year probabilities of disease-free survival (95.2% vs. 59.3%, P = 0.008) and overall survival (95.2% vs. 59.6%, P = 0.032) of allogeneic stem cell transplantation group were significantly better than high-dose cytarabine group in cohort after 2003 of acute myeloid leukaemia patients with t(8;21). The relative risk of overall survival with allogeneic stem cell transplantation, compared with high-dose cytarabine chemotherapy, was significantly improved in the cohort after 2003 (0.33; 95% CI, 0.07-1.48) when compared with that before 2003 (1.92; 95% CI, 0.77-4.82). In multivariate analysis in cohort after 2003, allogeneic stem cell transplantation as post-remission therapy was associated with better disease-free survival.

CONCLUSIONS:

Allogeneic stem cell transplantation is currently the more effective post-remission therapy than it was prior to 2003 for core binding factor acute myeloid leukaemia achieving first remission. On the contrary to previous findings, allogeneic stem cell transplantation provides significantly improved outcomes than high-dose cytarabine chemotherapy in acute myeloid leukaemia with t(8;21).
