Abstract
Objective: To investigate p16, C-fos protein expression and their relationships in osteosarcoma. Methods: Immunohistochemical technique (SABC) was used to detect p16 and C-fos protein expression in 41 cases of osteosarcoma. Results: The positive rates of p16 and C-fos protein expression were 51.2% and 82.9% respectively. Their expression was not correlated to pathological subtype, but correlated to clinic grade, and the latter was associated with tumor metastasis. There was a negative correlation between p16 and C-fos protein expression. Conclusion: The alteration of p16 and C-fos protein expression may be related to the tumorigenesis and development of osteosarcoma, and C-fos proteins may take part in osteosarcoma metastasis. These data will offer useful helpness to determine the prognosis of osteosarcoma.
