The Relationship with the Protein Expression of p53,PTEN and the Three-year Survival Ratios in Osteosarcoma Patients / 实用放射学杂志

ABSTRACT

Objective To explore the protein expression of p53 and PTEN in osteosarcoma and the relationship between them and the three-year survival ratios of osteosarcoma patients.Methods The protein expression of p53 and PTEN was detected using immunohistochemical methods in 53 cases of osteosarcoma proved by surgery and pathology. Results There was significant difference between the both kind of relationship with the protein expression of PTEN and the three-year survival ratios of osteosarcoma patients who had negative expression of p53. There was no significant difference between the both kind of relationship with the protein expression of PTEN and the three-year survival ratios of osteosarcoma patients who had positive expression of p53. PTEN expression,which was analysed by logistic regression, was entered the regression model ,but p53 expression was not. Conclusion PTEN expression is more important than p53 expression in predicting the prognosis of the patient with osteosarcoma.
