Abstract

Aim: Acute myeloid leukemia (AML) is an aggressive hematopoietic clonal disorder characterized by the increased blasts and poor survival outcome, which is mainly driven by cytogenetic and molecular abnormalities. Here, we investigated the prognostic impact of other demographic parameters on the survival outcomes in AML patients.

Method: We reviewed the Surveillance, Epidemiology, and End Result (SEER) database to collect demographic information, including age, diagnosis, gender, race, and geographic region in patients with non-acute promyelocytic leukemia AML, between 2004–2008. The primary end-point of our study was 3-year overall survival (OS), which was estimated by the Kaplan–Meier method and Cox regression model.

Results: A total of 13,282 patients were included in our analyses. Increasing age (HR 1.2, p < .0001), male gender (HR 1.05, p = .01), and geographic region of Midwest (HR 1.07, p = .002) were associated with inferior 3-year OS in univariate analysis, and these parameters remained independent prognostic factors in multivariate analyses.

Conclusions: AML is a heterogeneous myeloid neoplasm with patient outcomes largely dictated by the cytogenetics and somatic mutations. In our study, additional demographic factors, including advanced age, male gender, and geographic region of AML diagnosis were associated with OS outcome in non-APL AML patients.
