Regarding the three inflammatory mediators previously studied and found to be associated with fever in pediatric patients with ALL (6) in the present study, we observed that the median TNF-α was of 104.7 pg/mL (24.31–303.3 pg/mL) (Figure 2A), that of IL-8 was 69.19 pg/mL (8.23–623.2 pg/mL) (Figure 2B), and that of IL-10 was 88.58 pg/mL (37.83–1287 pg/mL) (Figure 2C) at the time of diagnosis. This evidence concerns the gene CXCL8 and acute lymphoblastic leukemia.
