Abstract

To study the expression and clinical significance of p63 gene in laryngeal squamous cell carcinoma(LSCC). The immunohistochemical technique was used to detected the expression of p63 in 63 cases of LSCC, 45 cases of para-cancer tissues, 24 cases of lymph node metastasis, 40 cases of non lymph node metastasis and 25 normal tissues. The positive overexpression rate of the p63 gene in LSCC (95.24%) and in matched metastatic lymph node (83.3%) was significantly higher than para cancer tissues, non metastasis lymph node and normal tissues (P<0.01). p63 gene expression was not correlation with the clinical stages,clinical typing and pathological classification of the LSCC(P >0.05). p63 gene had important clinic significance to the diagnosis and differential diagnosis of the LSCC. It perhaps participate in regulation of tumorigenesis in LSCC, and it may play negative feedback action in the development of LSCC.
