Background:Pyroptosis is essential for the remodeling of tumor immune microenvironment and suppression of tumor development. However, there is little information available about pyroptosis-related gene polymorphisms in non-small cell lung cancer (NSCLC).Methods:Six SNPs in theGSDMB,GSDMC, andAIM2were genotyped in 650 NSCLC cases and 650 healthy controls using a MassARRAY platform.Results:Minor alleles of rs8067378, rs2305480, and rs77681114 were associated with a lower risk of NSCLC (p< 0.005), whereas rs2290400 and rs1103577 were related to an increased risk (p< 0.00001). Moreover, rs8067378-AG/GG, rs2305480-GA/AA, and rs77681114-GA/AA genotypes were associated with a decrease in NSCLC risk (p< 0.005). In contrast, the TC/CC genotypes of rs2290400 and rs1103577 were associated with an elevated NSCLC risk (p< 0.0001). Based on the analysis of genetic models, minor alleles of rs8067378, rs2305480 and rs77681114 were related to reduced risk of NSCLC (p< 0.05); whereas rs2290400 and rs1103577 were related to increased risk (p< 0.01).Conclusion:Our findings provided new insights into the roles of pyroptosis-related genes in NSCLC, as well as new factors to be considered for assessing the risk of developing this cancer.
