ABSTRACT
The role of allogeneic stem cell transplantation (HSCT) as compared to chemotherapy in acute myeloid leukaemia (AML) patients with abnormalities of chromosome 17p [abnl(17p)] has not yet been defined. Therefore, we analysed 3530 AML patients treated in three randomized, prospective, controlled clinical trials and compared post-remission therapies using a multivariate Cox regression analysis to determine whether allogeneic HSCT is superior than chemotherapy in overcoming the detrimental impact of patients with abnl(17p) AML. One hundred and forty-three patients (4%) were identified with abnl(17p) AML. All patients had received intensive induction chemotherapy. Forty-seven patients with a median age of 54 years (18-69 years) proceeded to allogeneic HSCT in first or second remission. The 3-year overall survival (OS) rate for the entire cohort of patients was 4% [95% confidence interval (CI), 1-7%]. OS and event-free survival at 3 years, calculated from the day of HSCT, was 11% (95% CI, 2-20%) and 6% (95% CI, 0-13%), respectively. Multivariate Cox regression analysis showed no benefit of allogeneic HSCT compared to chemotherapy (Hazard Ratio 0·97, 95% CI 0·56-1·67, P = 0·9). In conclusion, allogeneic HSCT does not improve survival in patients with abnl(17p) AML as compared to other adverse cytogenetic risk abnormalities.
