However, the clinicopathological significance of LKB1, EMT, salt-inducible kinase 1 (SIK1), ZEB1 and their relationship in early stage non-small cell lung cancer (ES-NSCLC) patients remain to be determined. In this study, the correlation among expression of LKB1, risk of distant metastasis, prognostic significance, and EMT in ES-NSCLC after surgery was investigated by immunohistochemistry. Methods: Case notes and pathology records of 103 patients with ES-NSCLC were retrospectively analyzed. Immunohistochemical staining was employed to detect LKB1, EMT biomarkers (E-cadherin and vimentin), SIK1 and ZEB1 expression in ES-NSCLC tissues. Results: LKB1 expression is associated with distant metastasis after treatment (P=0.017). LKB1-high expression group has better overall survival (OS) (P=0.000) and disease-free survival (DFS) (P=0.000). LKB1 expression is correlated with E-cadherin (r=0.231, P=0.019), vimentin (r=−0.225, P=0.022), SIK1 (r=0.218, P=0.027) and ZEB1 (r=−0.242, P=0.014). Conclusions: Our findings suggest that LKB1-high expression is possibly associated with favourable prognosis and LKB1 expression is correlated with EMT and expression of SIK1 and ZEB1.
