OBJECTIVE: To study the expression of VEGF in sinonasal squamous cell carcinoma and its correlations with microvessel density (MVD), microlymphatic vessel density (MLVD).
METHOD: The expression of VEGF, MVD and MLVD in 41 cases of sinonasal squamous cell carcinoma were detected by immunohistochemical technique.
RESULT: In the sinonasal squamous cell carcinoma, the positive rate of VEGF was 82.9% (34/41). The over expression of VEGF was related with tumor invasion, histological grading and lymphatic metastasis (P < 0.05). The MVD of cases with positive VEGF expression was significantly higher than those without VEGF expression (P < 0.05), but was not statistical difference in MLVD (P > 0.05).
CONCLUSION: VEGF may participate in the metastasis of sinonasal squamous cell carcinoma through promoting vascularization in the tumors, but not promoting MLVD.
