Socioeconomic deprivation is associated with decreased survival in patients with acute myeloid leukemia

BACKGROUND

Socioeconomic deprivation is associated with poor prognosis in patients with solid tumors. However, few studies have assessed the association between socioeconomic parameters and prognosis in Acute Myeloid Leukemia (AML), and these report conflicting results. Our monocentric study assessed the impact of socioeconomic deprivation using the validated EPICES (Evaluation of Deprivation and Inequalities in Health Examination Centers) score in a prospective cohort of intensively treated AML patients.

METHODS

EPICES questionnaires were given to patients receiving intensive chemotherapy for newly diagnosed AML at the Paoli Calmettes Institute between July 2012 and December 2014. Study participants were categorized as non-deprived (score <30.17), deprived (score 30.17-48.51), or very-deprived (score ≥ 48.52). The primary endpoint was Overall Survival (OS). The independence of EPICES score effects was analyzed via Cox regression with adjustment for confounding factors.

RESULTS

209 AML patients received the questionnaire, 149 (71.3 %) patients responded. The median EPICES score was 23.6; 26.8 % and 10.1 % of patients were deprived and very deprived, respectively. OS was 23.16 months (95 %CI [17.15-33.31]). According to multivariate analysis, a very-deprived EPICES score, European Leukemia Net categories, age, smoking, and the absence of allogeneic stem cell transplantation were independent factors associated with decreased OS.

CONCLUSION

Our results underscore the importance of integrating nonbiological factors in the prognostic stratification of AML patients. The very deprived population exhibited worse OS, confirming that socioeconomic parameters play a role in patient outcomes in AML. Very deprived patients with AML should receive specific attention and adapted clinical management.
