PG - 966-9 AB - OBJECTIVE: To examine the expression and clinical significance of the Stat3 and Cyclin D1 in laryngeal squamous cell carcinoma (LSCC). METHOD: The expression of Stat3 and Cyclin D1 in LSCC tissue were detected by the RT-PCR and Western blot method respectively, and then the relationship between Stat3 and Cyclin D1 protein expression level and relevant clinical factors of LSCC was explored. RESULT: Compared to the normal larynx mucosa group, the expression level of Stat3 and Cyclin D1 was significantly higher in LSCC (P < 0.01). The high expression level of Stat3 and Cyclin D1 protein in LSCC was correlated with the clinical stage, tumor differentiation and lymph node metastases (P < 0.01). The expression level of Stat3 was positively correlated with that of Cyclin D1, The correlation coefficient(r) was 0.564 (P < 0.01) for the protein expression and 0.552 (P < 0.01) for the mRNA expression. CONCLUSION: Stat3 signaling pathway may play an important role in the tumorigenesis and progression of LSCC. The expression level of Stat3 and its target gene Cyclin D1 can reflect the malignancy degree of LSCC.
