ABSTRACT
OBJECTIVE@#To investigate the expression and significance of vascular cell adhesion molecule-1 (VCAM-1) and P-selectin in hypopharyngeal carcinoma, and explore the relationship of VCAM-1, P-selectin and microvessel density (MVD).@*METHOD@#Expression of VCAM-1 and P-selectin were detected by immunohistochemistry staining in 40 specimens of hypopharyngeal carcinoma and 10 specimens of normal mucosa of oral pharynx. MVD was assessed based on the expression of CD34.@*RESULT@#VCAM-1 and P-selectin were detected in 26 out of 40 (65%) and 29 out of 40 (72.5%) respectively in hypopharyngeal carcinoma, but none that in normal mucosa (P<0.01). MVD in hypopharyngeal carcinoma was higher than that in normal mucosa and it was related to lymph node metastasis. MVD level was significantly higher in VCAM-1 and P-selectin-positive specimens than in negative ones (P<0.01), which also positively correlated with the expression of VCAM-1 and P-selectin (P<0.01). The expression of P-selectin positively correlated with VCAM-1 in hypopharyngeal carcinoma specimens with lymph node metastasis.@*CONCLUSION@#The higher expression of VCAM-1 and P-selectin play key roles in the invasion and metastasis of hypopharyngeal carcinoma and were correlated with vascularization.
