Purpose: Relapsed acute myeloid leukemia (AML) post allogeneic hematopoietic cell transplantation (allo-HCT) has a dismal prognosis. Experimental Design: To assess prognosis of patients with recurrent AML post allo-HCT over time, we analyzed European Society for Blood and Marrow Transplantation registry data of 8,162 adult patients with AML who relapsed between 2000 and 2018 after allo-HCT performed in first complete remission from matched sibling, unrelated, or haploidentical donors. Results: The 2-year overall survival (OS) rate from relapse was 17%. For 3,630 patients, <50 years of age, the 2-year OS continuously increased from 16% between 2000 and 2004 to 18% for 2005-2009, to 21% for 2010-2014, and to 26% for 2015-2018 (P ¼ 0.001). Improvement over time was noted both after relapse within and beyond 6 months from allo-HCT. On multivariate analysis among patients <50 years of age, OS was positively affected by a later year of relapse (baseline: 2000-2004; HR, 0.82; P < 0.02 for 2010-2014 and HR, 0.72; P ¼ 0.0002 for 2015-2018), good performance status, favorable cytogenetics, and longer time from transplant to relapse, but negatively affected by increasing age. In contrast, among 4,532 patients, >50 years of age, the year of relapse had no influence on OS (16% for 2000-2004 and 14% for 2015-2018; P ¼ 0.56). Regarding treatment, encouraging results were observed after second allo-HCT, which was performed within 2 years after relapse in 17% of the entire cohort, resulting in a 2-year OS of 30.7%. Conclusions: Outcome after posttransplant relapse among younger patients has improved significantly in recent years, likely reflecting, among other factors, the efficacy of posttransplant salvage including second allo-HCT.

Abstract

Purpose: Relapsed acute myeloid leukemia (AML) post allogeneic hematopoietic cell transplantation (allo-HCT) has a dismal prognosis. Experimental Design: To assess prognosis of patients with recurrent AML post allo-HCT over time, we analyzed European Society for Blood and Marrow Transplantation registry data of 8,162 adult patients with AML who relapsed between 2000 and 2018 after allo-HCT performed in first complete remission from matched sibling, unrelated, or haploidentical donors. Results: The 2-year overall survival (OS) rate from relapse was 17%. For 3,630 patients, <50 years of age, the 2-year OS continuously increased from 16% between 2000 and 2004 to 18% for 2005-2009, to 21% for 2010-2014, and to 26% for 2015-2018 (P ¼ 0.001). Improvement over time was noted both after relapse within and beyond 6 months from allo-HCT. On multivariate analysis among patients <50 years of age, OS was positively affected by a later year of relapse (baseline: 2000-2004; HR, 0.82; P < 0.02 for 2010-2014 and HR, 0.72; P ¼ 0.0002 for 2015-2018), good performance status, favorable cytogenetics, and longer time from transplant to relapse, but negatively affected by increasing age. In contrast, among 4,532 patients, >50 years of age, the year of relapse had no influence on OS (16% for 2000-2004 and 14% for 2015-2018; P ¼ 0.56). Regarding treatment, encouraging results were observed after second allo-HCT, which was performed within 2 years after relapse in 17% of the entire cohort, resulting in a 2-year OS of 30.7%. Conclusions: Outcome after posttransplant relapse among younger patients has improved significantly in recent years, likely reflecting, among other factors, the efficacy of posttransplant salvage including second allo-HCT.
