ABSTRACT
<p><b>OBJECTIVE</b>To investigate the association between the rs2274223 and rs3765524 polymorphism of phospholipase C epsilon 1 (PLCE1) gene and the susceptibility to develop esophageal squamous cell carcinoma (ESCC) in a pure Kazakh Chinese population.</p><p><b>METHODS</b>Matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS) was utilized to genotype the potentially functional single nucleotide polymorphism rs2274223 A>G and rs3765524 C>T of PLCE1 in an ongoing hospital-based and case-control study of 200 ESCC cases with 300 cancer-free age ( ± 5 years) and sex matched controls. Statistical analyses were performed with Statistical Products and Services Solutions software (version 13.0). Adjusted odds ratios (OR) and 95% confidence evaluation intervals (95%CI) measured by multivariate logistic regression analysis were adopted to study the correlation of the gene polymorphism with the susceptibility to ESCC.</p><p><b>RESULTS</b>The genotype frequencies observed for rs2274223 was consistent with Hardy-Weinberg equilibrium in controls. Univariate analysis revealed significant differences between cases and controls with respect to genotype distribution for rs2274223 (P = 0.006). The variants of rs2274223 were found to confer significantly increased risk of ESCC (GG vs AA OR = 3.17, 95%CI = 1.45-6.93; AG/GG vs AA OR = 1.55, 95%CI = 1.08-2.22) in the Kazakh Chinese population. Moreover, AG/GG genotype of rs2274223 was found to be significantly associated with poorly-differentiated ESCC (OR = 2.48, 95%CI = 1.10-5.60). When the ESCC patients were divided into two subgroups, stage I/II and stage III/IV according to the AJCC TNM classification, the GT/GG genotype of rs2274223 was significantly associated with stage III/IV ESCC (OR = 1.85, 95%CI = 1.05-3.25). No significant association was found between rs3765524 and Kazakh ESCC.</p><p><b>CONCLUSIONS</b>These results indicate that rs2274223 site polymorphism of the PLCE1 gene is strongly associated with risk of ESCC in a Kazakh Chinese population, especially the poorly-differentiated and stage III/IV ESCC.</p>
