摘要:

目的 探讨miR-924和溶质载体家族1成员5(SLC1A5)在肺癌患者预后评估中的价值。方法 选取2018年2月—2019年2月南阳市中心医院肺癌患者97例,收集所有患者的临床资料,并收集癌组织和癌旁组织(距肿瘤边缘>2 cm),检测miR-924、SLC1A5 mRNA和SLC1A5蛋白表达。采用Pearson相关分析评估miR-924与SLC1A5 mRNA的相关性。采用Kaplan-Meier生存曲线评估肺癌患者的生存情况。采用Cox回归分析评估肺癌患者预后不良的危险因素。结果 与癌旁组织比较,癌组织miR-924相对表达量降低(P<0.001),SLC1A5 mRNA相对表达量升高(P<0.001)。癌组织SLC1A5蛋白阳性率显著高于癌旁组织(P<0.001)。癌组织miR-924表达与SLC1A5 mRNA表达呈负相关(r=-0.843,P<0.05)。根据癌组织miR-924相对表达量均值或SLC1A5蛋白的表达情况分别分为高表达组、低表达组和阳性组、阴性组。miR-924低表达组与高表达组之间、SLC1A5阳性组与阴性组之间分化程度、临床分期差异均有统计学意义(P<0.05)。Kaplan-Meier生存曲线分析结果显示,miR-924高表达组累积生存率高于低表达组(Log-rank χ2=5.453,P<0.05);SLC1A5阳性组累积生存率低于阴性组(Log-rank χ2=9.259,P<0.05)。多因素Cox回归分析结果显示,临床分期Ⅲ期、miR-924低表达、SLC1A5蛋白表达阳性均是肺癌患者预后不良的危险因素(P<0.05)。结论 肺癌患者癌组织miR-924和SLC1A5均呈异常表达,或可作为肺癌预后评估的生物标志物。

Abstract:

Objective To investigate the prognostic assessment roles of miR-924 and solute carrier family 1 member 5(SLC1A5) in lung cancer tissues. Methods From February 2018 to February 2019,97 lung cancer patients from Nanyang Central Hospital were enrolled,and the general data and cancer and adjacent tissues(>2 cm from tumor edges) were collected. The miR-924 and SLC1A5 mRNA and SLC1A5 expressions were determined. The correlation between miR-924 and SLC1A5 mRNA was analyzed by Pearson correlation analysis. Kaplan-Meier survival curve was used,and Cox regression analysis was used to analyze the risk factors for the poor prognosis of lung cancer patients. Results Compared with adjacent tissue group,the relative expression level of miR-924 in cancer tissue group was decreased(P<0.001),while that of SLC1A5 mRNA and the positive rate of SLC1A5 were increased(P<0.001). The miR-924 expression was negatively correlated with SLC1A5 mRNA in lung cancer tissue(r=-0.843,P<0.05). The research subjects were classified into high-expressed group,low-expressed group and positive group,negative group according to the mean value of miR-924 relative expression level or the expression of SLC1A5,respectively. There was statistical significance in the differentiation degree and clinical stage between miR-924 low-expressed group and high-expressed group and between SLC1A5 positive group and negative group(P<0.05). The cumulative survival rate of miR-924 high-expressed group was higher than that of miR-924 low-expressed group(Log-rank χ2=5.453,P<0.05),and the cumulative survival rate of SLC1A5 positive group was lower than that of SLC1A5 negative group(Log-rank χ2=9.259,P<0.05). Clinical stage Ⅲ,low expression of miR-924 and positive SLC1A5 were risk factors for poor prognosis of lung cancer patients(P<0.05). Conclusions The lung cancer patients has abnormal expressions of miR-924 and SLC1A5 in cancer tissue,which are expected to become the markers for evaluating lung cancer prognosis.
