To investigate the expression and prognostic value of CCL2 in gastric cancer, as well as its relationship with tumor hypoxia.
Tumor tissues from 68 gastric cancer patients (GC) were analyzed, and the expression of CCL2 and hypoxia-inducible factor 1 alpha (HIF-1α) in tumor tissues was detected by immunohistochemistry. Statistical evaluations that were used included univariate log-rank tests of Kaplan-Meier curves and multivariate Cox regression model analysis.
CCL2 was highly expressed in 66.2% (45/68) of gastric cancer specimens. The distribution of CCL2 expression in tumor tissue was consistent with that of HIF-1α. Patients with high CCL2 expression in GC had a lower overall survival rate [50.6 mo (95%CI: 44.44-56.93) vs 64.6 mo (95%CI: 60.27-68.94), P = 0.013].
CCL2 expression correlates closely with HIF-1α expression in gastric cancer. CCL2 may be an independent prognostic marker for GC.
探讨趋化因子配体2(CCL2)在胃癌中的表达及其预后价值,以及其与肿瘤缺氧的关系。
分析68例胃癌患者的肿瘤组织,采用免疫组化法检测肿瘤组织中CCL2和缺氧诱导因子1α(HIF-1α)的表达。采用Kaplan-Meier曲线的单因素对数秩检验和多因素Cox回归模型分析进行统计学评估。
66.2%(45/68)的胃癌标本中CCL2高表达。CCL2在肿瘤组织中的表达分布与HIF-1α一致。胃癌中CCL2高表达的患者总生存率较低[50.6个月(95%CI:44.44-56.93)对64.6个月(95%CI:60.27-68.94),P = 0.013]。
CCL2表达与胃癌中HIF-1α表达密切相关。CCL2可能是胃癌的一个独立预后标志物。
