Relationship between Nestin expression and prognosis in human osteosarcoma / 实用医学杂志

ABSTRACT

Objective To explore the relationship between Nestin expression level and prognosis in osteosarcoma,and to provide a new idea for treatment.Methods Thirty patient with osteosarcoma who had received treatment were included this study according to the criteria.HE staining was applied to evaluate the response to chemotherapy,meanwhile immunohistochemistry was applied to evaluate Nestin expression levels before and after chemotherapy.Kaplan Meier survival curve was drawn to analyze the outcomes.Results The response of chemotherapy was good in 17 patients and poor in 13.24 cases were strongly positive in Nestin staining,five were weakly positive,and one was negative.The expression level of Nestin in osteosarcona was correlated to the chemotherapy response and prognosis (P ＜ 0.05),while higher level of Nestin expression referred to poorer response of chemotherapy and lower overall survival rate.Conclusions The expression level of Nestin in osteosarcoma tissue is associated with the effect of chemotherapy and prognosis;higher expression level of Nestin indicates poorer prognosis and efficacy of chemotherapy.
