目的

探讨miR-145-5p表达水平与肝细胞癌(肝癌)临床病理特征及其预后的关系。

方法

通过分析Gene Expression Omnibus(GEO)中肝癌芯片数据,采用实时荧光定量PCR方法检测肝癌临床手术组织标本及其癌旁正常组织、肝癌细胞系及石蜡包埋肝癌组织中miR-145-5p相对表达量,分析其与肝癌临床病理特征的关系,并进行Kaplan-Meier生存曲线及单因素和多因素分析影响肝癌患者总体生存的危险因素。

结果

miR-145-5p在肝癌细胞系、肝癌组织中表达分别低于正常肝细胞和癌旁组织(P<0.001);miR-145-5p的相对表达量与转移及肿瘤分化相关参数肿瘤数目(P=0.040)、脉管侵犯(P=0.010)、Edmondson-Steiner分级(P=0.011)、BCLC分期(P=0.003)有关。Cox多因素分析发现,肿瘤数目、脉管侵犯、Edmondson-Steiner分级、BCLC分期和miR-145-5p表达量是影响肝癌患者总体生存的独立危险因素(HR=2.864、2.114、3.157、4.106、3.594;均P<0.05),同时也是影响肝癌患者无病生存的独立危险因素(HR=1.764、1.880、3.726、3.443、1.909,均P<0.05)。

结论

miR-145-5p低表达与肝癌侵袭转移有关,可能是提高晚期肝癌患者预后的潜在新靶点。

Objective

To investigate the relationship between miR-145-5p expression level and the clinicopathological characteristics and prognosis of hepatocellular carcinoma (HCC).

Methods

The relative expression of miR-145-5p in fresh frozen HCC and paraneoplastic tissues, HCC cell lines and formalin-fixed paraffin-embedded HCC tissues was detected by quantitative real-time PCR (qPCR), and HCC microarray data in GEO were also analyzed. The relationship between expression of miR-145-5p and clinicopathological characteristics of HCC was analyzed, and Kaplan-Meier curve and Cox proportional risk regression model were used for prognostic analysis.

Results

miR-145-5p expression was lower in HCC cell lines and HCC tissues than in normal hepatocytes and paraneoplastic tissues (P<0.001). miR-145-5p low expression group was associated with metastasis and poor differentiation related parameters: tumor number (P=0.040), vascular invasion (P=0.010), Edmondson-Steiner grading (P=0.003). Cox proportional risk regression model identified tumor number, vascular invasion, Edmondson-Steiner grading, BCLC stage, and miR-145-5p expression as independent risk factors for overall survival in patients with HCC (HR=2.864, 2.114, 3.157, 4.106, 3.594; all P<0.05), and they were also independent risk factors for disease-free survival in patients with HCC (HR=1.764, 1.880, 3.726, 3.443, 1.909; all P<0.05).

Conclusion

Low expression of miR-145-5p is associated with aggressive metastasis of HCC and is expected to be an effective therapeutic target to improve the prognosis of advanced HCC.
