Influence of Body Mass Index on Incidence and Prognosis of Acute Myeloid Leukemia and Acute Promyelocytic Leukemia: A Systematic Review and Meta-Analysis

Abstract Background: Previous studies have demonstrated an association between high body mass index (BMI) and acute myeloid leukemias (AML), particularly acute promyelocytic leukemia (APL). However, the effect of obesity and overweight on the incidence of AML is not supported by all studies, and the relationship between obesity and prognosis of AML and APL has not been established. Thus, we conducted a meta-analysis to determine the role of BMI on the risk and clinical outcome of AML, including APL. Methods: A literature search (last search updated to Dec. 4, 2016) was conducted in PubMed, EMBASE, Web of Science and the Cochrane Library for articles assessing the effect of overweight and obesity on the incidence and clinical outcome of AML. In all,twenty-six eligible studies enrolling 12,971 AML (including 866 APL) patients were retrieved and analyzed. Results: Both overweight and obesity was associated with an increased incidence of AML (for overweight, relative risk [RR], 1.10; 95% CI, 1.03-1.17; P=0.007; I2=43.1%; fixed effects; and for obesity, RR, 1.41; 95% CI, 1.24-1.61; P Conclusion: Our findings suggest that patients with overweight or obesity have a higher incidence of AML. While no significant effect was found on the clinical outcome of non-APL AML, high BMI indicates worse overall survival and higher risk of differentiation syndrome in APL. .
