PG - 1641-4 AB - OBJECTIVE: To study the expression of DNA-dependent protein kinase (DNA-PK) in human laryngeal squamous cell carcinoma (LSCC) and normal laryngeal mucosa (NLM), and to analysize the relationship between the expression and the clinicopathologic parameters of LSCC. METHOD: Immunohistochemical technique (Envision) was used to detect the expression of DNA-PK in 64 cases of LSCC and 15 cases of NLM. To investigate an investigation was conducted on the relationship between the expression and clinico-pathological features of LSCC. RESULT: DNA-PK was lowly expressed in NLM and highly expressed in LSCC,the positive rate of DNA-PK expression was 26.67% (4/15), 78.13% (50/64), respectively, and there was significant different difference between the two groups (P < 0.05). Its expression was correlated with the level of histodifferentiation (P < 0.05), but not with TNM stages and neck lymph node metastasis (P > 0.05). CONCLUSION: DNA-PK may be involved in disease development of LSCC.
