Objective:
This study aims to investigate the correlation between polymorphism of sex hormone-binding globulin (SHBG) Asp327Asn (rs6259) locus and occurrence of hepatocellular carcinoma (HCC).
Methods:
621 cases with HCC and 621 cancer-free controls from two hospitals of Guangxi were recruited from January, 2007 to June, 2010. Single nucleotide polymorphisms (SNP) of SHBG Asp327Asn were detected by ABI7500 Fast Real-Time fluorescence quantitative PCR. Multivariate unconditional logistic regression was applied to analyze risk of HCC among different genotypes carriers and their interaction with the exposure factors. The Kaplan-Meier survival analysis was used to detect the relationship between onset age of HCC and genotypes.
Results:
The frequencies of Asp/Asp, Asp/Asn and Asn/Asn genotype in case group were 86.31% (536/621), 12.40% (77/621) and 1.29% (8/621), respectively; while those in control group were 81.00% (503/621), 17.39% (108/621) and 1.61% (10/621), respectively. Significant difference in the genotype frequencies distribution was found between case and control groups (χ2=6.465, P<0.05). Compared with those harboring Asp/Asp genotype, multivariate logistic regression analysis revealed that the HCC risk of Asn/Asn+Asp/Asn genotype carriers was significantly decreased (adjusted OR=0.63, 95%CI: 0.40-0.98). Interaction analysis showed that there was interaction between the polymorphisms and two exposure factors, drinking (adjusted OR=3.45, 95%CI: 1.74-6.83) and HBV infection (adjusted OR=40.77, 95%CI: 21.60-76.97). Among those male patients with history of drinking, survival analysis indicated that the mean age of onset of individuals harboring Asp/Asp genotypes ((47.99±0.75) years-old) was 6 years earlier than those with Asn/Asn or Asp/Asn genotypes ((53.68±2.07) years-old) (χ2=6.91, P<0.01).
Conclusion:
Polymorphism of SHBG (Asp327Asn) may be associated with both the risk of HCC occurrence and onset age of HCC.
