To detect the expression of Per2 in non-small cell lung cancer (NSCLC), and analyze its clinical significance. The expression of Per2 was determined in 60 NSCLC and 20 normal lung tissues by immunohistochemical assay, and the relationship between Per2 expression and clinicopathological features was analyzed. The positive expression rates of Per2 in NSCLC and normal lung tissues were 71.7% and 95.0%, respectively (P < 0.05). The expression of Per2 in NSCLC was correlated with pathological differentiation and TNM stage (P < 0.05). The expression of Per2 in NSCLC is decreased. The negative expression of Per2 may contribute to the development and invasion in NSCLC.
