Inflammation-related Gene Polymorphisms Associated With Childhood Acute Lymphoblastic Leukemia.

BACKGROUND: Acute lymphoblastic leukemia (ALL) is a malignant hematological disease and is often accompanied by a variety of genetic abnormalities. The pathogenesis of inflammation-related single-nucleotide polymorphism (SNP) in children with ALL remains unclear. OBJECTIVE: This study was to discover the association of the SNP sites of some inflammation-related genes and the susceptibility and treatment response of ALL in children, so as to provide personalized treatment for ALL in children. PROCEDURE: One hundred sixty-five childhood ALL patients and 175 age-matched healthy participants were recruited in this study. We investigated the involvement of 31 SNPs of the inflammation-related genes in the pathogenesis and treatment response of childhood ALL. RESULTS: Statistical analysis revealed that rs2280714 in IRF5, rs2297630 in SDF-1, rs4353135 in NLRP3, rs1946518 in interleukin-18 were related to the susceptibility to pediatric ALL. Interleukin-1ß rs16944 SNP was correlated with ALL risk stage in children. Rs7633631 in CD226 and rs10818488 in TRAF1 were related to the minimal residual disease (MRD) on day 15 and day 33. CONCLUSIONS: Certain SNPs of inflammation genes were associated with the susceptibility and treatment response of ALL children. These findings may help in the early detection, diagnostic evaluation, and making individual chemotherapy regimen for ALL children according to the genotype of these sites at the time of initial diagnosis.
