Abstract:
ObjectiveTo study the expression and potential significance of NET-1 in endometrial carcinoma.Methods106 specimens after operation were selected.All specimens were stained with H.E.and immunohistochemistry.ResultsThe expression of NET-1 immunoreactivity were different in normal endometrium(43.8％ ),endometrial hyperplasia ( 79.2％ ) and endometrial carcinoma ( 100％ ) ( x2 =11.88,P ＜ 0.01 ).The expression of NET-1 in endometrial carcinoma was significantly higher than that in normal endometrium and simple endometrial hyperplasia ( x2 =36.14,10.86,P ＜ 0.01 ).The expression of NET-1 in endometrial hyperplasia was significantly higher than that in normal endometrium ( x2 =5.29,P＜ 0.05 ).There was a correlation between the expression of NET-1 and degree of endometrial lesions ( r =0.355,P ＜0.01 ).The expression of NET-1 was relative with differentiation (x2 =11.04,P ＜0.01 ; r =0.558,P ＜0.01),stages(x2 =11.04,P ＜0.01; r =0.558,P ＜0.01),depth of myometrial invasion (x2 =15.90,P ＜0.01 ; r =0.479,P ＜0.01),with or without metastasis in lymph node ( Z =-3.74,P ＜0.01 ),menopause condition ( Z.=-2.60,P ＜0.01).ConclusionsNET-1 may play an important role in carcinogenesis and progression of endometrial carcinoma.It might be a marker of biological behavior and reference for endometrial carcinoma gene therapy.
