摘要:

目的 探讨胃癌患者微小RNA-7-5p(miR-7-5p)、神经肿瘤腹侧抗原2(NOVA2)表达的变化及其与预后的相关性。方法 选取2014年3月—2015年3月邯郸市第一医院行手术治疗的胃癌患者86例,收集癌组织和癌旁组织(距肿瘤边缘5 cm)。收集所有患者的临床资料,并检测miR-7-5p和NOVA2表达。采用Kaplan-Meier生存曲线分析胃癌患者的生存情况,采用Cox回归分析评估影响胃癌患者预后的风险因素。结果 胃癌组织miR-7-5p相对表达量显著低于癌旁组织(P<0.05),NOVA2阳性表达显著高于癌旁组织(P<0.05)。不同年龄、性别、肿瘤直径、TNM分期、浸润深度、组织病理学分级和有无淋巴转移胃癌患者miR-7-5p相对表达量和NOVA2阳性表达差异有统计学意义(P<0.05)。Kaplan-Meier生存曲线分析结果显示,miR-7-5p高表达组5年生存率显著高于低表达组(χ2=15.226,P<0.05),NOVA2阴性组5年生存率显著高于NOVA2阳性组(χ2=22.547,P<0.05)。miR-7-5p、NOVA2均是影响胃癌患者总生存率的危险因素[风险比(HR)分别为1.668、1.764,95%可信区间(CI)分别为1.523~1.799、1.315~2.214]。结论 胃癌患者癌组织中miR-7-5p表达下调,NOVA2表达上调,与临床病理特征均显著相关。miR-7-5p和NOVA2或可作为胃癌病情监测和预后判断的指标。

Abstract:

Objective To investigate the expression changes of microRNA-7-5p(miR-7-5p) and neuro-oncological ventral antigen 2(NOVA2) in patients with gastric cancer,and to analyze the correlation with clinical prognosis. Methods A total of 86 patients with gastric cancer who underwent surgical treatment in the First Hospital of Handan from March 2014 to March 2015 were enrolled. Their cancer tissues and adjacent tissues(5 cm from tumor edge) were collected. The clinical data were collected. The miR-7-5p levels and the expression of NOVA2 were determined. Kaplan-Meier survival curve was used to analyze the survival of patients with gastric cancer,and Cox regression analysis was used to evaluate the risk factors affecting the prognosis of patients with gastric cancer. Results The relative expression level of miR-7-5p in cancer tissues was lower than that in adjacent tissues(P<0.05),and the positive expression of NOVA2 was higher than that in adjacent tissues(P<0.05). The relative expression level of miR-7-5p and positive expression of NOVA2 had statistical significance with age,sex,tumor diameter,TNM stage,lymph metastasis,depth of invasion and histopathological grade of patients with gastric cancer(P<0.05). Kaplan-Meier survival curve analysis showed that the 5-year survival rate of high miR-7-5p expression group was higher than that of low miR-7-5p expression group(χ2=15.226,P<0.05),and the 5-year survival rate of NOVA2 negative expression group was higher than that of NOVA2 positive expression group(χ2=22.547,P<0.05). The miR-7-5p and NOVA2 were factors that affected the total survival rate of patients with gastric cancer [hazard ratios(HR) were 1.668 and 1.764,95% confidence intervals(CI) were 1.523-1.799 and 1.315-2.214]. Conclusions The expression of miR-7-5p is down-regulated,and NOVA2 is up-regulated in cancer tissues of patients with gastric cancer,which is correlated with clinicopathologic features. Therefore,miR-7-5p and NOVA2 may be used as indicators for the monitoring and prognostic judgment of gastric cancer.
