Changing frontline AML treatment patterns from 2013 to 2022

Abstract

The treatment patterns for patients with newly diagnosed acute myeloid leukemia (AML) were compared between 2013 and 16 and 2021-22 in a real-world setting. A significantly higher proportion of patients age 70 and over received non-intensive therapy (NIT) in 2021-22 as compared with 2013-16 (65 % vs 44 %, p = 0.014), with a corresponding reduction in the proportion receiving either intensive therapy or no antileukemic treatment. Treatment patterns among patients < age 70 were unchanged. The complete response rate in the NIT group was 69 % in 2021-22 vs. 24 % in 2013-16 (p < 0.001); the overall survival (OS) of NIT patients was 11.5 months in 2021-22 vs. 7.8 months in 2013-16. Older patients from rural areas were more likely to decline therapy than those from urban regions. The increase in the proportion of patients opting for NIT may be related to the availability of more effective treatment options. Although outcomes are improving, the OS with NIT remains suboptimal.
