This case-control study aimed to investigate the role of -251 T>A (rs4073) and -781 C>T (rs2227306) polymorphisms in the interleukin-8 (IL-8) gene in the development of glioma in a Chinese population. One hundred and twenty-seven glioma patients and 284 healthy control subjects were recruited to this study between February 2013 and December 2014. The IL-8 -251 T>A (rs4073) and -781 C>T (rs2227306) polymorphisms were genotyped by polymerase chain reaction coupled with restriction fragment length

The patients and control subjects were comparable by gender (c 2 = 1.24, P = 0.27), tobacco smoking status (c 2 = 0.80, P = 0.37), alcohol consumption status (c 2 = 0.97, P = 0.32), and family history of cancer (c 2 = 1.54, P = 0.22). The age of glioma patients was statistically lower than that of control subjects (t = 2.87, P = 0.002). The chisquare test revealed the lack of any statistically significant differences in the genotype distributions of IL-8 rs4073 (c 2 = 0.89, P = 0.64) and rs2227306 (c 2 = 2.58, P = 0.28) between the glioma patients and control subjects. Unconditional logistic regression analysis revealed that the 2 J.W. Fu et al. Genetics and Molecular Research 15 (3): gmr.15038127 IL-8 rs4073 and rs2227306 gene polymorphisms did not contribute to the development of glioma. In conclusion, we determined that there is a lack of evidence suggesting a significant association between the IL-8 rs4073 and rs2227306 gene polymorphisms and the development of glioma in a Chinese population.
