Abstract: Presented study aims to explore the predictive values of serum microRNA-22 (miR-22) and miR-126 levels for non-small cell lung cancer (NSCLC) development and metastasis.
A total of 127 NSCLC patients who were admitted in the First People’s Hospital of Yancheng City from May, 2013 to May, 2015 were selected as the case group, including 71 cases of adenocarcinoma and 56 cases of squamous cell carcinoma. There were 112 healthy individuals selected as the control group. The qRT-PCR was performed to testify the serum miR-22 and miR-126 levels. Logistic regression analysis was conducted to analyze independent factors influencing NSCLC metastasis and receiver operating characteristic (ROC) curve was drawn to analyze the sensitivity and specificity of serum miR-22 and miR-126 levels in predicting NSCLC developments and metastasis.
The serum miR-22 level was significantly higher in the case group than that in the control group, while the serum miR-126 level was lower in the case group as compared with that in the control group. Compared with squamous cell carcinoma patients, serum miR-22 level significantly increased, while serum miR-126 level decreased in patients with adenocarcinoma. Patients at III + IV stage showed increased serum miR-22 level and relatively decreased serum miR-126 level as compared to patients at I + II stage. Serum miR-22 level elevated in patients with metastasis; in contrast serum miR-126 level reduced in comparison to those without metastasis. In patients with familial inheritance, serum miR-22 level increased but serum miR-126 level decreased as compared to those without familial inheritance. The specificity and sensitivity of serum miR-22 and miR-126 levels in predicting NSCLC development were 99.11%, 84.30%, 82.68% and 96.40%, respectively. The specificity and sensitivity of serum miR-22 and miR-126 levels in predicting NSCLC metastasis were 59.74%, 96.00%, 84.00% and 62.30%, respectively.
Results indicated that serum miR-22 and miR-126 levels may be used as the predicative biomarkers for NSCLC development and metastasis.
