ABSTRACT
OBJECTIVE@#To discuss the expression and correlation of COX2 and LMP1 in NPC.@*METHOD@#Fifty-three nasopharyngeal biopsy specimens of NPC patients who had been diagnosed definitely with pathology in our department from 2000 to 2005, and 8 nasopharyngeal biopsy specimens of chronic nasopharyngitis patients were collected. The expression of COX2, LMP1 were detected with streptavidin peroxidase immunohistochemistry staining. All the datas were analyzed with SPSS 12.0.@*RESULT@#The positive expression rate of COX2 was 71.70% (38/53), and that of LMP1 was 66.04% (35/53) of Nasopharyngeal carcinoma tissue. The higher expression rate was detected in neck lymph nodes metastasis group of nasopharyngeal carcinoma (P0.05). The expression of COX2 and LMP1 showed positive correlation (gamma = 0.797, P<0.01).@*CONCLUSION@#COX2 and LMP1 were highly expressed in nasopharyngeal carcinoma cells. The expressions of COX2 and LMP1 was significantly associated with neck lymph nodes metastasis, and was none-significant relation with age, gender, clinical stage and pathological classification. The expression of LMP1 showed a significant positive correlation with that of COX2. LMP1 could enhance NPC neck lymph nodes metastasis by up-regulating the expression of COX2.
