The present paper aims to investigate whether or not vasculogenic mimicry (VM) exists in laryngeal squamous cell carcinoma (LSCC), and to elucidate its relationship to microvessel density (MVD), galectin-3 (Gal-3) expressionb and clinicopathological factors of patients with LSCC. VM, score of MVD and expression of Gal-3 protein were detected by immunohistochemistry and histochemistry in 83 specimens of LSCC tissue and 20 specimens of normal laryngeal tissue. The positive rate of VM in normal laryngeal tissues was 0%, and was 33.7% in LSCC tissues. There was a significant difference between the two groups (P<0.01). VM or MVD was significantly related to differentiation, pTNM stages and lymph node metastasis of LSCC (P<0.05), but not to age, gender and tumor site (P>0.05). And there was a positive correlation between every two of VM, score of MVD, and Gal-3 protein (P<0.05). The results suggest that expression of Gal-3 protein may be related to the initiation, angiogenesis and VM formation in LSCC; And VM, angiogenesis and Gal-3 protein may be involved in the development, invasion and metastasis of LSCC.
