PG - 824-6 AB - OBJECTIVE: To investigate the role of CDK2 in the development of DNA heteroploid in laryngeal squamous cell carcinoma (LSCC). METHOD: Fifty specimens of LSCC, twelve specimens of atypical hyperplasia and thirty specimens of vocal cord polyp were obtain during operation. Centrosome were detected by anti tubulin antibodies. Immunohistochemical method was used to analyze the protein expression of CDK2 and gamma-tubulin. RESULT: The positive rate of CDK2 and gamma-tubulin in LSCC were 68.0% (34/50) and 78.0% (10/15), all of them were significant higher than those in the vocal cord polyp (P<0.05). Expression of CDK2 in LSCC was positively association with expression of gamma-tubulin. CONCLUSION: This experiment indicated that overexpression of CDK2 was strongly correlated with abnormal proliferation in LSCC, and it may be a valuable marker for the diagnosis and therapy of LSCC.
