Objective To detect the expression of vascular cell adhesion molecule-1(VCAM-1)in oral squamous cell carcinoma(OSCC),and explore its relationship with the microvessel density in OSCC.Methods Expression of VCAM-1 and CD31 in 48 cases of OSCC and 10 cases of normal oral mucosa was detected by immunohistochemistry.Microvessel density was assessed based on the expression of CD31.Results VCAM-1 was expressed not only in the squamous cancer cell but also in vascular endothelial cells.VCAM-1 was detectable in 31 out of 48(64.58%)cases of OSCC and none in 10(0.00%)cases of normal oral mucosa(P0.01).Microvessel density was higher in OSCC than in normal oral mucosa and was related to lymph node metastasis and infiltration depth.Microvessel density was significantly higher in VCAM-1-postive OSCC than in VCAM-1-negative OSCC(P0.01),and also positively correlated with the expression of VCAM-1(P0.01).Conclusion Over-expression of VCAM-1 in OSCC may be closely correlated with cancer angiogenesis.
