Abstract

The present study aimed to investigate the expression levels and clinical value of miR‑365 and miR‑25 in serum of patients with non‑small cell lung cancer (NSCLC). Patients (180) diagnosed with NSCLC at the Affiliated Hospital of Guangdong Medical University from July 2011 to December 2013 were used as the experimental group. Volunteers (90) undergoing health examinations were used as the control group. The serum of the patients was collected after fasting in the morning. The expression levels of miR‑365 and miR‑25 in the serum of patients was assessed by quantitative real‑time PCR (qRT‑PCR), and the relationship among miR‑365, miR‑25 and the postoperative survival rate of NSCLC patients was analyzed. The relative expression level of miR‑25 of patients with peripheral infiltration was significantly higher than that of patients without peripheral infiltration (P<0.05). There were significant differences in the relative expression level of miR‑25 in different pathological grades and TNM stages, as well as with lymph node metastasis (P<0.05). The survival rate of NSCLC patients with high expression of miR‑25 was significantly lower than that of NSCLC patients with low expression of miR‑25 (P<0.05). The relative expression level of miR‑365 of patients with peripheral infiltration was significantly lower than that of patients without peripheral infiltration (P<0.05). There were significant differences in the relative expression level of miR‑365 in different pathological grades and TNM stages, as well as with lymph node metastasis (P<0.05). The survival rate of NSCLC patients with high expression of miR‑365 was significantly higher than that of NSCLC patients with low expression of miR‑365 (P<0.05). In conclusion, the expression levels of miR‑25 and miR‑365 were different in the serum of NSCLC patients, and they were closely related to certain clinical characteristics such as peripheral infiltration, pathological grade, tumor diameter, TNM stage and lymph node metastasis. Moreover, it was revealed that miR‑25 and miR‑365 affected the 5‑year survival rate of patients. miR‑25 and miR‑365 could be used as important tumor markers to evaluate the prognosis of NSCLC patients.
