Moreover, leptin levels were higher in patients with ALL than in controls (range: 5.4–22.5 vs. 3.0–15.4, p = 0.00), and adiponectin levels were lower in patients with ALL and AML (range 9.8–15.5 in ALL, and 0.7–9.6 in AML, and 12.9–22.0 in controls, p = 0.01). This evidence concerns the gene ADIPOQ and acute lymphoblastic leukemia.
