血清miR-145和miR-195在OSCC患者中的表达及其与颈部淋巴结转移的关系分析

Expression of serum miR-145 and miR-195 in OSCC patients and their relationship with cervical lymph node metastasis

目的 分析血清微小RNA(miR)-145和miR-195在口腔鳞状细胞癌(OSCC)患者中的表达及其与颈部淋巴结转移的关系。方法 选取2020年1月至2022年6月在该院确诊的102例OSCC患者为OSCC组,收集整理OSCC患者临床病理参数,根据是否发生颈部淋巴结转移将患者分为颈部淋巴结转移组43例和无颈部淋巴结转移组59例;同期选取79例癌前病变患者为癌前病变组,86例无口腔病变的体检健康者为健康对照组。采用实时荧光定量聚合酶链反应检测血清miR-145、miR-195相对表达水平;采用受试者工作特征曲线分析检验血清miR-145、miR-195相对表达水平对OSCC患者颈部淋巴结转移的评估价值。结果 OSCC组血清miR-145、miR-195相对表达水平低于癌前病变组、健康对照组,差异有统计学意义(P<0.05)。癌前病变组血清miR-145、miR-195相对表达水平低于健康对照组,差异有统计学意义(P<0.05)。肿瘤低分化、TNM分期Ⅲ+Ⅳ期的OSCC患者血清miR-145、miR-195相对表达水平低于肿瘤中/高分化、TNM分期Ⅰ+Ⅱ期的OSCC患者,差异有统计学意义(P<0.05)。颈部淋巴结转移组血清miR-145、miR-195相对表达水平低于无颈部淋巴结转移组,差异有统计学意义(P<0.05)。血清miR-145、miR-195相对表达水平单独及二者联合评估OSCC患者颈部淋巴结转移的曲线下面积分别为0.840(95%CI:0.765~0.915)、0.832(95%CI:0.754~0.910)、0.898(95%CI:0.841~0.956),特异度分别为79.1%、88.4%、77.5%,灵敏度分别为74.6%、67.8%、87.4%。结论 血清miR-145、miR-195在OSCC患者中低表达,且与OSCC患者颈部淋巴结转移、肿瘤分化程度、TNM分期有关,可作为评估OSCC患者颈部淋巴结转移的重要指标。

Objective To analyze the expression of serum microRNA(miR)-145 and miR-195 in patients with oral squamous cell carcinoma(OSCC)and their relationship with cervical lymph node metastasis.Methods A total of 102 patients diagnosed with OSCC in the hospital from January 2020 to June 2022 were selected as OSCC group.Clinicopathological parameters of OSCC patients were collected and sorted.According to whether cervical lymph node metastasis occurred,the patients were divided into a cervical lymph node metastasis group(43 cases)and a non-cervical lymph node metastasis group(59 cases).In the same period,79 patients with precancerous lesion were selected as the precancerous lesion group,and 86 healthy subjects without oral disease were selected as the healthy control group.Real-time fluorescence quantitative polymerase chain reaction was used to detect the relative expression levels of serum miR-145 and miR-195.The evaluation value of relative expression levels of serum miR-145 and miR-195 in cervical lymph node metastasis in OSCC patients was examined by receiver operating characteristic curve analysis.Results The relative expression levels of serum miR-145 and miR-195 in OSCC group were lower than those in precancerous lesion group and healthy control group,and the difference was statistically significant(P<0.05).The relative expression levels of serum miR-145 and miR-195 in precancerous lesion group were lower than those in healthy control group,and the difference was statistically significant(P<0.05).The relative expression levels of serum miR-145 and miR-195 in OSCC patients with low tumor differentiation and TNM stageⅢ+Ⅳwere lower than those in OSCC patients with medium/high tumor differentiation and TNM stageⅠ+Ⅱ,with statistical significance(P<0.05).The relative expression levels of serum miR-145 and miR-195 in cervical lymph node metastasis group were lower than those in non-cervical lymph node metastasis group,and the difference was statistically significant(P<0.05).The relative expression levels of serum miR-145 and miR-195 were 0.840(95%CI:0.765-0.915),0.832(95%CI:0.754-0.910)and 0.898(95%CI:0.754-0.910)of cervical lymph node metastasis in OSCC patients respectively.The specificity was 79.1%,88.4%and 77.5%,and the sensitivity was 74.6%,67.8%and 87.4%,respectively.Conclusion Serum miR-145 and miR-195 are low expressed in OSCC patients,and are related to cervical lymph node metastasis,tumor differentiation,and TNM stage in OSCC patients,which can be used as an important indicator to evaluate cervical lymph node metastasis in OSCC patients.
