BACKGROUND/AIMS: Biological and epidemiological data suggest that vitamin D levels may influence cancer development. Several single nucleotide polymorphisms have been described in the vitamin D receptor (VDR) gene in association with cancer risk. We aimed to investigate the association of VDR gene polymorphisms with hepatocellular carcinoma (HCC) development in chronic hepatitis C patients.
METHODS
In a cross-sectional, hospital-based setting, 340 patients (201 chronic hepatitis, 47 cirrhosis and 92 HCC) and 100 healthy controls receiving VDR genotyping (bat-haplotype: BsmI rs1544410 C, ApaI rs7975232 C and TaqI rs731236 A) were enrolled.
RESULTS
Patients with HCC had a higher frequency of ApaI CC genotype (P = 0.027) and bAt[CCA]-haplotype (P = 0.037) as compared to control subjects. There were no differences in BsmI and TaqI polymorphisms between two groups. In patients with chronic hepatitis C, HCC subjects had a higher frequency of ApaI CC genotype and bAt[CCA]-haplotype than those with chronic hepatitis (P = 0.001 and 0.002, respectively) and cirrhosis (P = 0.019 and 0.026, respectively). After adjusting age and sex, logistic regression analysis showed that ApaI CC genotype (odds ratio: 3.02, 95% confident interval: 1.65-5.51) was independently associated with HCC development.
CONCLUSION
VDR ApaI polymorphism plays a role in the development of HCC among chronic hepatitis C patients. Further explorations of this finding and its implications are required.
背景/目的：生物学和流行病学数据表明，维生素 D 水平可能会影响癌症的发生。维生素 D 受体（VDR）基因中已有多种单核苷酸多态性与癌症风险相关。我们旨在研究 VDR 基因多态性与慢性丙型肝炎患者肝癌（HCC）发展的关系。
方法
在一项横断面、基于医院的研究中，纳入了 340 名患者（201 名慢性肝炎、47 名肝硬化和 92 名 HCC）和 100 名健康对照者进行 VDR 基因分型（蝙蝠单倍型：BsmI rs1544410 C、ApaI rs7975232 C 和 TaqI rs731236 A）。
结果
与对照组相比，HCC 患者 ApaI CC 基因型（P = 0.027）和 bAt[CCA]-单倍型（P = 0.037）的频率更高。两组之间 BsmI 和 TaqI 多态性无差异。在慢性丙型肝炎患者中，HCC 患者的 ApaI CC 基因型和 bAt[CCA]-单倍型频率高于慢性肝炎患者（P = 0.001 和 0.002）和肝硬化患者（P = 0.019 和 0.026）。在校正年龄和性别后，Logistic 回归分析显示 ApaI CC 基因型（比值比：3.02，95%置信区间：1.65-5.51）与 HCC 发展独立相关。
结论
VDR ApaI 多态性在慢性丙型肝炎患者 HCC 的发展中起作用。需要进一步探索这一发现及其意义。
