ABSTRACT
OBJECTIVE@#To explore the expression of cyclooxygenase-2 (COX-2) and S-100 positive dendritic cell in laryngeal carcinoma tissue and their clinical significance.@*METHOD@#Sixty-five samples of laryngeal carcinoma and thirty-four biopsies of adjacent noncancerous tissue were obtained. Immunohistochemical technique (SP method) was used to detect the expression of COX-2 and S-100 positive dendritic cell, and the relationship of their expression with clinical pathological parameters and prognosis was analyzed.@*RESULT@#The rates of COX-2 expression were 63.08% (41/65)and 14.70% (5/34) in laryngeal carcinoma and control group, respectively. The difference was significant (P < 0.05). The positive expression of COX-2 was correlated with T and clinical stage in laryngeal carcinoma(all P < 0.05). The rates of S-100 positive dendritic cell expression were 61.54% (40/65)and 0 in laryngeal carcinoma and control group, respectively. The difference was significant (P < 0.05). S-100 positive dendritic cells showed significant differences between early and late clinical stage and lymph node metastasis (all P < 0.05). Kaplan-Meier survival analysis showed that patients with positive expression of COX-2 and S-100 positive dendritic cell had worse disease-free and overall survival (P < 0.05). Cox regression analysis showed that S-100 positive dendritic cell was indicated as an independent prognostic factor for survival(P < 0.05).@*CONCLUSION@#COX-2 and S-100 positive dendritic cell are highly expressed in laryngeal carcinoma tissue. It suggests that the expression of COX-2 and S-100 positive dendritic cell is related to the process of carcinogenesis and may be the important indicators in laryngeal carcinoma for prognosis.
