宫颈癌患者血清miR-651、miR-630水平及临床意义

Levels and clinical significance of serum miR-651 and miR-630 in patients with cervical cancer

目的探究宫颈癌患者血清微小RNA(miR)-651和miR-630水平及临床意义。方法收集2017年6月至2020年5月入院治疗的宫颈癌患者108例为宫颈癌组,同时选取在我院治疗的宫颈上皮内瘤变(CIN)患者100例为CIN组,以及同期在本院健康体检者110例为对照组。实时荧光定量PCR(qRT-PCR)检测血清miR-651、miR-630水平,分析血清miR-651、miR-630与宫颈癌患者临床特征和预后的关系。结果宫颈癌组、CIN组血清miR-651、miR-630水平显著低于对照组(P<0.05),宫颈癌组血清miR-651、miR-630水平显著低于CIN组(P<0.05)。血清miR-651与miR-630表达水平呈正相关(r=0.660,P<0.05)。血清miR-651、miR-630水平与HPV感染、分化程度、淋巴结转移、FIGO分期有关(P<0.05)。miR-651和miR-630低水平患者总生存率低于高水平患者。Cox回归分析表明,HPV感染、分化程度、淋巴结转移、FIGO分期、miR-651、miR-630均是宫颈癌患者预后的影响因素(P<0.05)。结论宫颈癌患者血清miR-651、miR-630水平降低,两者与HPV感染、分化程度、淋巴结转移、FIGO分期及预后有关。

Objective To investigate the levels and clinical significance of serum microRNA(miR)-651 and miR-630 in patients with cervical cancer.Methods From June 2017 to May 2020,108 cervical cancer patients accepted by our hospital were collected as the cervical cancer group.Meantime,100 cervical intraepithelial neoplasia(CIN)patients treated in our hospital were regarded as the CIN group,and 110 healthy individuals who underwent physical examination were regarded as the control group.Real-time fluorescence quantitative PCR(qRTPCR)was applied to detect serum levels of miR-651 and miR-630,while analyzing the relationship between serum miR-651 and miR-630 as well as clinical features and prognosis of patients.Results The serum levels of miR-651 and miR-630 in the cervical cancer group and CIN group were obviously lower than those in the control group(P<0.05),while the serum levels of miR-651 and miR-630 in the cervical cancer group were obviously lower than those in the CIN group(P<0.05).The expression levels of serum miR-651 and miR-630 were positively corre⁃lated(r=0.542,P<0.05).The serum levels of miR-651 and miR-630 were related to HPV infection,differentia⁃tion,lymph node metastasis,and FIGO staging(P<0.05).The overall survival rate of patients with low levels of miR-651 and miR-630 was lower than that of patients with high levels.Cox regression analysis showed that,HPV infection,degree of differentiation,lymph node metastasis,FIGO staging,miR-651,and miR-630 were all influ⁃encing factors for the prognosis of cervical cancer patients(P<0.05).Conclusion The serum levels of miR-651 and miR-630 in cervical cancer patients decrease,which are related to HPV infection,differentiation,lymph node metastasis,FIGO staging,and prognosis.
