This study was aimed to investigate the associations between single nucleotide polymorphisms of cancer stem cell marker genes, CD44 and CD133, and susceptibility and prognosis of gastric cancer.
PATIENTS & METHODS: Five single nucleotide polymorphisms in CD44 and CD133 genes were genotyped in 898 gastric cancer cases and 992 controls.
The A/C or C/C genotypes of CD133 rs2240688 were associated with decreased risk of gastric cancer comparing with the A/A genotype (odds ratio: 0.81; 95% CI: 0.67-0.97; p = 0.023). The T allele of CD133 rs3130 predicted a worse survival for gastric cancer patients receiving tumorectomy (hazard ratio: 1.28; 95% CI: 1.04-1.58; p = 0.020), independent from tumor node metastasis stage, vessel invasion and postoperational chemotherapy.
CD133 polymorphisms are promising biomarkers for genetic susceptibility and prognosis prediction of gastric cancer.
本研究旨在探讨癌症干细胞标志物基因CD44和CD133的单核苷酸多态性与胃癌易感性及预后之间的关联。
对898例胃癌病例和992例对照进行CD44和CD133基因的5个单核苷酸多态性基因分型。
与A/A基因型相比，CD133 rs2240688的A/C或C/C基因型与胃癌风险降低相关（优势比：0.81；95%可信区间：0.67 - 0.97；p = 0.023）。CD133 rs3130的T等位基因预测接受肿瘤切除术的胃癌患者生存较差（风险比：1.28；95%可信区间：1.04 - 1.58；p = 0.020），独立于肿瘤淋巴结转移分期、血管侵犯和术后化疗。
CD133多态性是胃癌遗传易感性和预后预测的有前景的生物标志物。
