This study aimed at investigating the prevalence of anxiety and depression, and their risk factors as well as their correlation with prognosis in refractory or relapsed (R/R) acute myeloid leukemia (AML) patients.A total of 180 R/R AML patients were enrolled and their anxiety and depression were assessed by Hospital Anxiety and Depression Scale (HADS) before treatment. Besides, HADS was also evaluated in 180 de novo AML patients prior treatment and 180 healthy controls (HCs), respectively.Both the HADS-Anxiety and HADS-Depression scores were increased in R/R AML patients compared with de novo AML patients and HCs (all P < .001). Meanwhile, the prevalence of anxiety and depression was 53.9% and 45.6% in R/R AML patients, which were also greatly higher compared with de novo AML patients and HCs (all P < .01). Regarding risk factors, higher Eastern Cooperative Oncology Group score and lines of salvage therapy were correlated with anxiety and depression in R/R AML patients (all P < .05). Furthermore, anxiety and depression were associated with shorter overall survival (OS) in R/R AML patients (all P < .05), while no association of different degrees of anxiety and depression with OS was observed (all P > .05).Anxiety and depression are highly prevalent and implicated in the management and prognosis of R/R AML.
