METHODS: We enrolled 1127 cases newly diagnosed with HCC from the Tumor Hospital of Guangxi Medical University and 1200 non-tumor patients from the First Affiliated Hospital of Guangxi Medical University. General demographic characteristics, behavioral information, and hematological indices were collected by unified questionnaires. Genomic DNA was isolatedfrom peripheral venous blood using Phenol-Chloroform. The genotyping was performed using the Sequenom Mass ARRAY i PLEX genotyping method. The association between genetic polymorphisms and risk of HCC was shown by P-value and the odd ratio(OR) with 95% confidence interval(CI) using the unconditional logistic regression after adjusting for age, sex, nationality, smoking, drinking, family history of HCC, and hepatitis B virus(HBV) infection. Moreover, stratified analysis was conducted on the basis of the status of HBV infection, smoking, and alcohol drinking.RESULTS: The HCC risk was lower in patients with the MCM4 rs2305952 CC(OR = 0.22, 95%CI: 0.08-0.63, P = 0.01) and with the CHEK1 rs515255 TC, TT, TC/TT(OR = 0.73, 95%CI: 0.56-0.96, P = 0.02; OR = 0.67, 95%CI: 0.46-0.97, P = 0.04; OR = 0.72, 95%CI: 0.56-0.92, P = 0.01, respectively). Conversely, the HCC risk was higher in patients with the KAT2 B rs17006625 GG(OR = 1.64, 95%CI: 1.01-2.64, P = 0.04). In addition, the risk was markedly lower for those who were carriers of MCM4 rs2305952 CC and were also HBs Ag-positive and non-drinking and nonsmoking(P < 0.05, respectively) and for those who were carriers of CHEK1 rs515255 TC, TT, TC/TT and were also HBs Ag-negative and non-drinking(P < 0.05, respectively). Moreover, the risk was higher for those who were carriers of KAT2 B rs17006625 GG and were also HBs Ag-negative(P < 0.05).CONCLUSION: Of 12 cell cycle pathway genes, MCM4, CHEK1 and KAT2 B polymorphisms may be associated with the risk of HCC.展开更多
