Abstract:
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 me-tastasis 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 with-out 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 lev-els 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 stage Ⅲ+Ⅳ were lower than those in OSCC patients with medium/high tumor differentiation and TNM stage Ⅰ+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 OS-CC patients.
