Abstract
OBJECTIVE: To evaluate the expression of vascular endothelial growth factor C (VEGF-C), Epstein-Barr virus (EBV) latent membrane protein 1 (LMP1), cyclooxygenase-2 (COX-2) in nasopharyngeal carcinoma (NPC). METHOD: LMP1, COX-2 and VEGF-C were detects by immunohistochemical staining for 57 case NPC tissue. RESULT: The positives rates of LMP1, COX-2 and VEGF-C detected by immunohistochemical staining were 49.1% (28/57), 75.4% (43/57) and 59.6% (34/57), respectively. The expression of LMP1, COX-2 and VEGF-C were correlated to each other in NPC (P < 0.05). CONCLUSION: LMP1 and COX-2 may induce expression of VEGF-C directly or LMP1 induce expression of VEGF-C by induce COX-2 expression, may contribute to lymph metastasis and develop NPC.
