Abstract
- OBJECTIVE: To investigate the expression and clinical significance of miRNA-99a and miRNA-224 in the serum of patients with non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: 83 patients with NSCLC, who were diagnosed and treated in our hospital from January 2014 to September 2017, were included in the experiment group. 79 patients, who made health check up, were included in the control group. The quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) technique was used to test the expressions of miRNA-99a and miRNA-224 in the serum of the patients in the two groups, and the relationship between the expression levels of miRNA-99a and miRNA-224 and the clinicopathological features of the patients with NSCLC was analyzed; the correlation between the expression of miRNA-99a and the expression of miRNA-224 in NSCLC was also analyzed. RESULTS: The expression level of miRNA-99a in the patients with NSCLC was significantly lower than that in the patients in the normal control group; the differences were statistically significant (p<0.001). The expression level of miRNA-224 in the patients with NSCLC was markedly higher than that in the patients in the normal control group; the differences were statistically significant (p<0.001). The expression level of miRNA-99a in the patients with NSCLC was remarkably correlated with pathological stage, the presence or absence of lymph node metastasis and tissue differentiation (p<0.001). The expression level of miRNA-224 in the patients with NSCLC was significantly correlated with pathological stage, the presence or absence of lymph node metastasis and pathological grade (p<0.001). The results of partial correlation analysis showed that the expression levels of miRNA-99a and miRNA-224 were negatively correlated with each other in NSCLC (r=-0.985, p<0.001). CONCLUSIONS: MiRNA-99a and miRNA-224 may be involved in the development and progression of NSCLC. MiRNA-99a is associated with NSCLC pathological stage, lymph node metastasis and tissue differentiation, while miRNA- 224 is associated with NSCLC pathological stage, lymph node metastasis and pathological grade. MiRNA-99a and miRNA-224 can be used as clinical monitoring indicators for NSCLC. [ABSTRACT FROM AUTHOR]
