Abstract
Background: Interleukin?10 (IL?10) and tumor necrosis factor?alpha (TNF??) genes contribute to oncogenesis. We evaluated the influence of the IL?10 (G1082A) and TNF?? (G308A) polymorphisms on the prognosis and outcomes of Egyptian patients with acute lymphoblastic leukemia (ALL). Materials and Methods: We investigated 64 children and 76 adults with ALL, between 2016 and 2019, for the IL?10 (G1082A) and TNF?? (G308A) polymorphisms using allele?specific polymerase chain reaction and polymerase chain reaction杛estriction fragment length polymorphism. Survival analyses were performed using the Kaplan朚eier estimator and the log?rank test. Results: In children with ALL, the A allele of TNF?? and IL?10 polymorphisms was associated with older age (P = 0.04 and 0.03), more extramedullary disease (P = 0.02 and 0.001), positive breakpoint cluster region朅belson (BCR?ABL) rearrangement (p190; P = 0.04 and 0.001), and more relapse (P = 0.002). The IL?10 GG genotype was associated with higher overall survival in children (P = 0.026). Adults carrying the TNF?? A allele showed more extramedullary disease (P = 0.009) and relapse (P = 0.003). We also found a higher frequency of IL?10 A allele in adults with older age (P = 0.03), lower hemoglobin level (P = 0.04), positive BCR?ABL rearrangement (P = 0.001), more extramedullary disease (P = 0.001), more relapse (P = 0.002), and a longer time for the first complete remission (P = 0.003). Conclusion: A possible association exists between the A allele of IL?10 and TNF?? polymorphisms and poor prognosis in Egyptian patients with ALL, while the IL?10 GG genotype may be associated with better survival in children with ALL.
