Human leukocyte antigen-G (HLA-G) expression plays an important role in the diagnosis and grading of endometrial cancer
The research aimed to investigate the expression of human leukocyte antigen G (HLA-G) in cancer tissues and normal endometrium and the expression of HLA-G in the three different grades of Endometrial cancer, to determine if HLA-G expression is related with the diagnosis and grading of endometrial cancer. The expression of HLA-G protein was analysed in the primary tumour in 97 tissue samples obtained from endometrial cancer, in which 30 samples were at pathological Grade 1; 37 samples were at Grade 2; 27 samples were at Grade 3; and the other 5 samples were obtained from normal endometrium. The HLA-G protein level was measured by immunohistochemical method and analysed according to the clinicopathological parameters of patients. A statistically significant difference (
