Abstract Acute myeloid leukemia (AML) is primarily a disease of the elderly and the numbers of these patients are increasing. Patients ≥60 years of age continue to have poor prognosis. Preliminary results suggest benefit from reduced-intensity allogeneic hematopoietic cell transplantation (HCT) in selected patients 60-80 years of age. However, although patients in this age range comprise >50% of those with AML, they currently constitute only 17% of those offered HCT. In the absence of prospective randomized studies comparing HCT and chemotherapy, the decision to recommend HCT rests on retrospective analyses of the risks of relapse and nonrelapse mortality after each approach. There is strong evidence that pre-HCT comorbidities can predict HCT-related morbidity and mortality. Age alone does not appear predictive and, particularly if the risk of relapse with chemotherapy is high, should not be the sole basis for deciding against HCT. Use of geriatric assessment tools, inflammatory biomarkers, and genetic polymorphism data may further aid in predicting nonrelapse mortality after HCT. Disease status and pretreatment cytogenetics with FLT3-TID, NPM-1, and CEBP-α status are the main factors predicting relapse and these are likely to be supplemented by incorporation of other molecular markers and the level of minimal residual disease after chemotherapy. HLA-matched related and unrelated donor grafts seem preferable to those from other donor sources. Donor age is of no clear significance. Models combining comorbidities with AML risk factors are useful in risk assessment before HCT. In this chapter, we integrated information on AML-specific, HCT-specific, and patient-specific risk factors into a risk-adapted approach to guide decisions about HCT versus no HCT.

The Benefit of Allogeneic Hematopoietic Cell Transplantation in Older Patients with Acute Myeloid Leukemia Is Restricted to Those in First Complete Remission At the Time of Transplantation.

Abstract Abstract 3097 Allogeneic hematopoietic cell transplantation (HCT) is a potentially curative treatment for some patients with acute myeloid leukemia (AML). Whether older patients with AML benefit from curative potential of HCT similar to younger patients is not well understood. To understand this issue, we evaluated the impact of age and remission status on 242 consecutive patients that underwent HCT between 1999 and 2011 in our program. Based on age and remission status, patients were divided into 4 groups: Gp 1, CR1 age <60 (n=116); Gp 2, CR1 age ≥60 (n=32); Gp 3, CR2 age <60 (n=78); and Gp 4, CR2 age ≥60 (n=16). Median age of all patients was 48 years (range 18–71), 123 patients (51%) were male. Peripheral blood stem cells were used in 178 patients (74%), bone marrow in 64 patients (26%). Donors were matched related (n=155, 64%) or matched unrelated (n=87, 36%). Median follow up of survivors was 65 months (range 12–145). No significant difference was found in terms of cytogenetic risk distribution between the 4 groups (p=0.14). Of the 48 patients ≥60 years of age, 46 (96%) received reduced-intensity conditioning regimens. Survival at 2-years in Gp 1, Gp 2, Gp 3, Gp 4 was 59%, 43%, 43% and 23%, respectively (Fig 1). Corresponding relapse free survival (RFS) was 59%, 34%, 40%, and 19%, respectively. Cumulative incidence (CI) of relapse in the four groups was 14%, 34%, 21% and 25% respectively. The corresponding CI of non-relapse mortality (NRM) was 27%, 31%, 38% and 56% respectively. In a univariate analysis, the hazard ratios for survival for Gp 2, Gp 3 and Gp 4 were 1.488, 1.533 and 2.718 in reference to Gp 1, respectively. Our data demonstrate that patients ≥60 years with AML in CR1 benefit from curative potential of HCT. Due to high NRM, patients ≥60 years in CR2 do not appear to benefit from curative potential of HCT. Therefore, if in an older patient HCT is indicated, attempts should be made to deliver the HCT in CR1. Disclosures: No relevant conflicts of interest to declare.
