肾上腺皮质肿瘤增殖抗原和脆性组氨酸三联体表达的相关性及意义

目的 研究肿瘤增殖抗原(Ki67)和脆性组氨酸三联体(FHIT)在肾上腺皮质肿瘤中的表达及其与肾上腺皮质肿瘤的关系.方法应用免疫组化方法检测75例肾上腺皮质肿瘤(腺瘤61例、腺癌14例)及10例瘤旁正常组织标本中Ki67及FHIT的表达情况.结果Ki67在正常肾上腺组织不表达,在腺癌表达最高,腺瘤次之;FHIT表达的情况相反.Ki67和FHIT在肾上腺皮质组织的表达呈负相关关系(r=-0.721,P<0.005).结论Ki67及FHIT的表达与肾上腺肿瘤显著相关,联合检测Ki67和FHIT在肾上腺皮质肿瘤的表达,为难以判断良、恶性的肾上腺皮质肿瘤提供较为客观、简捷的诊断方法.

Expression and significance of Ki67 and FHIT In adrenocortical tumor tissue

Objective To study relationship between Ki67 ,fragile histindine tried (FHIT) and adrenocortical tumors. Methods Ki67 and FHIT was detected by immunohistochemical staining in edrenecortical carcinoma(n=14) ,edrenocortical adenoma(n = 61) and normal adrenocortical tissue adjacent to tumor(n = 10). Results Ki67 was not expressed in normal adrenecortical tissue but highest expressed in adrenocortical carcinoma as well as in adrenocortical adenoma,and however,the expression of FHIT was expressed in a different way to Ki67. Negative correlation was observed between Ki67 and FHIT (r = -0.721 ,P <0.005). Conclusion The correlation of Ki67, FHIT with adrenocortical tumor, suggest that the detection of both Ki67 and FHIT can provide objective and simple diagnosis method to identify adrencortical adenomas from adrencortical carcinomas.
