RESUMO
OBJECTIVE: To investigate the expression and significance of Cyclin D1 in oral squamous cell ma (OSCC). METHODS: A immunohistochemistry method, Envosion, was employed to test the manifesting Cyclin D1 in pathological slices of 50 OSCC cases and 10 normal cases, and the results was treated with statistical lysis. RESULTS: In 50 OSCC cases, Cyclin D1 mainly manifested in karyon, and a little in cytoplasm. manifesting rates of Cyclin D1 in the samples was 80.0%, which was significantly higher than the manifesting of 20.0% in normal oral mucous membrane (P < 0.01). The manifestation of Cyclin D1 was correlated with rent pathological grades, clinical phases and lymph node metastasis (P < 0.05). CONCLUSION: The abnormal tation of Cyclin D1 is closely related with the occurrence and development of OSCC. Therefore, it can subsidiary index for OSCC treatment and prognosis.
