ABSTRACT
Objective To investigate the expressions of Ki67,p53,CKL,EMA,S-lOO,NSE,CgA,Syn,CEA and nm23 in adrenal tumors and their clinical significance.Methods Clinical data from 157 cases of adre-nal tumor patients were retrospectively reviewed including the clinical informa-tion and pathology data.Expressions of Ki67,p53,CKL,EMA,S-100,NSE,CgA,Syn,CEA and nm23 proteins were studied by immunohistochemistry(SP method)using monoclonal antibodies,and the relationship of their expressions with histopathologic type and clinical imformation was analyzed with SAS v6.12 software.A P value of<0.05 was considered statistically significant.Results A increase of the expression rate of CKL,S-100,NSE,CgA,Syn and nm23 in adrenal tumors was obsered(P<0.05).For univariate analysis,the expression of S-100,CgA,Syn was in connection with histopathologie types(P<0.05).The expression of S-100,CgA,Syn had positive correlation with each other.The expression of CKL,S-100,NSE,CgA,Syn,nm-23 was no difference between adrnalbenign tumors and malignant tumors(P>0.05),but it was much higher than in normal adrenal tissues(P<0.05).The expression of Syn in adrenal cortical adenomaa was higher than in adrenal cortical cancers(P<0.05),the expression of Ki67 in adrenal cortical adenomas was much lower than in adrenal cortical cancers(P<0.05).The expression of EMA、CKL in adrenal cortical tumors were higher than in adrenal medullary tumors(P<0.05),the expression of S-100,Syn,NSE,CgA in adrenal cortical tumors were lower than in adrenal medullary tumors(P<0.05).Conclusions CKL,S-100,NSE,CgA,Syn and nm23 were good markers for adrenal tumors,they could be use for the adrenal tumors diagnosis.Detect Syn and Ki67 simutaneously was helpful to the diagnosis of adrenal cortical tumors.Detect EMA,CKL,S-100,Syn,NSE and CgA simultaneously and combine with clinical data was helpful to diagnosis between adrenal cortical tumors and adrenal medullay tumors.In malignant tumors,blood pressure had positive correlation with the expression of CgA,the size of tumor had neg-ative correlation of blood pressure,no prognostic factor was found.
