Abstract
Background: Non-small cell lung cancer (NSCLC) has been the leading cause of cancer death in recent years, its morbidity and mortality were increasing yearly. The presence of vasculogenic mimicry (VM) is associated with a high tumor grade, short survival, invasion, and metastasis. Slug is a key regulating factor in the process of EMT. Vimentin is one of the cytoskeleton proteins that plays an important role in EMT. However, associations among VM, Slug and vimentin and their clinicopathologic significance in NSCLC are unclear. In this study, we analyzed associations among VM, Slug and vimentin in NSCLC, and their respective associations with clinicopathologic characteristics and survival in NSCLC. Methods: Positive expression of VM, Slug and vimentin in 198 whole NSCLC tissue samples were detected by immunohistochemical staining. Patients' clinical data were also collected. Results: Levels of VM, Slug and vimentin were significantly higher in NSCLC tissues than in normal lung tissues. Levels of VM, Slug and vimentin were positively associated with tumor grade, distant metastasis (DM), lymph node metastasis (LNM), and tumor-node metastasis (TNM) stage, and inversely with patients overall survival time (OST). In multivariate analysis, high expression of VM, Slug, vimentin, and tumor grade, DM, LNM, TNM stage, were potential to be independent prognostic factors for OST in patients with NSCLC. Conclusion: VM, Slug and vimentin affect NSCLC evolution; and the combined detection of VM, Slug and vimentin are valuable factors for metastasis and prognosis in NSCLC patients. IJCEP
