目的
2
分析胰腺癌组织中微小RNA-34a-5p(miR-34a-5p)表达对患者术后预后不良的预测价值。
方法
2
收集123例胰腺癌患者手术切除的胰腺癌组织和癌旁正常组织,检测胰腺癌组织和癌旁正常组织中miR-34a-5p表达。比较不同临床病理特征患者胰腺癌组织中miR-34a-5p的表达。根据预后情况将患者分为预后不良组和预后良好组,并比较2组患者临床资料。采用
Cox
回归模型分析胰腺癌患者预后不良的危险因素,绘制受试者工作特征(
ROC
)曲线分析胰腺癌组织中miR-34a-5p表达对患者预后不良的预测价值。
结果
2
胰腺癌组织中miR-34a-5p表达低于癌旁正常组织(
P
<
0.05)。分化程度、TNM分期、淋巴结转移情况不同的患者胰腺癌组织中miR-34a-5p表达差异有统计学意义(
P
<
0.05)。预后不良组患者低分化、TNM分期Ⅲ期、淋巴结转移、切缘R1占比和糖类抗原199(CA199)、中性粒细胞与淋巴细胞比值(NLR)、血小板/淋巴细胞比值(PLR)水平均高于预后良好组(
P
<
0.05),miR-34a-5p表达低于预后良好组(
P
<
0.05)。
Cox
回归分析显示,低分化、TNM分期Ⅲ期、淋巴结转移、切缘R1、miR-34a-5p表达降低和CA199、NLR、PLR水平升高均是患者预后不良的危险因素(
P
<
0.05);
ROC
曲线分析显示,胰腺癌组织中miR-34a-5p表达预测胰腺癌患者预后不良的最佳临界值为0.48,敏感度为78.82%,特异度为89.47%,曲线下面积为0.855,具有良好预测价值。
结论
2
胰腺癌组织中miR-34a-5p表达低于癌旁正常组织,且其表达与分化程度、TNM分期、淋巴结转移有关,亦是胰腺癌患者术后预后不良的危险因素和预测因子。
Objective
2
To analyze the predictive value of microRNA-34a-5p (miR-34a-5p) expression in pancreatic cancer tissue on postoperative poor prognosis.
Methods
2
The surgically resected pancreatic cancer tissues and normal tissues adjacent to cancer from 123 patients with pancreatic cancer were collected to detect the expression of miR-34a-5p. The expression of miR-34a-5p in pancreatic cancer tissues for patients with different clinicopathological characteristics were compared. The patients were divided into the poor prognosis group and the g
ood prognosis group according to their prognosis,and the clinical data of patients between the two groups was compared. The risk factors of poor prognosis for patients with pancreatic cancer were analyzed by
Cox
regression model,and the predictive value of miR-34a-5p expression in pancreatic cancer tissues on poor prognosis of patients was analyzed by
receiver operating characteristic
(
ROC
) curve.
Results
2
The expression of miR-34a-5p in pancreatic cancer tissues was lower than that in normal tissues adjacent to cancer (
P
<
0.05). There were statistically significant differences in the expression of miR-34a-5p in pancreatic cancer tissues of patients with different differentiation degrees,TNM stages,and lymph node metastasis (
P
<
0.05). The proportions of low differentiation,TNM stage for stage Ⅲ,lymph node metastasis and incisal margin of R1,and levels of carbohydrate antigen 199 (CA199),neutrophils/lymphocytes ratio (NLR) and platelet/lymphocyte ratio (PLR) for patients in the poor prognosis group were higher than those in the good prognosis group (
P
<
0.05),while miR-34a-5p expression was lower than that in the good prognosis group (
P
<
0.05).
Cox
regression analysis showed that low differentiation,TNM stage for stage Ⅲ,lymph node metastasis,incisal margin of R1,decreased expression of miR-34a-5p and increased levels of CA199,NLR and PLR were risk factors of poor prognosis for patients with pancreatic cancer(
P
<
0.05).
ROC
curve analysis showed that the optimal cut-off value of miR-34a-5p expression in pancreatic cancer tissue for predicting poor prognosis of patients was 0.48,the sensitivity was 78.82%,the specificity was 89.47% and the area under the curve was 0.855,with good predictive value.
Conclusion
2
The expression of miR-34a-5p in pancreatic cancer tissue is lower than that in normal tissue adjacent to cancer,and its expression is related to the differentiation degree,TNM stage and lymph node metastasis,which is also a risk factor and predictor of poor prognosis for patients with pancreatic cancer.
