Expression of SATB1 and E-cad in tissues of patients with endometrial carcinoma and the relationship with clinicopathological features

The expression of special AT-rich sequence binding protein 1 (SATB1) and E-cadherin (E-cad) in tissues of patients with endometrial carcinoma and the relationships with clinicopathological features were investigated. One hundred and four cases of carcinoma tissues and 104 cases of para-carcinoma tissues of patients pathologically diagnosed as endometrial carcinoma in Affiliated Hospital of Jining Medical University (Jining, China) from August 2015 to August 2016 were selected. The expressions of SATB1 and E-cad in tissues was detected via streptavidin peroxidase biotin (SP) immunohistochemical method, and the relationship with clinicopathological features of patients was analyzed. SATB1 was positively expressed in 71 out of 104 cases of endometrial carcinoma tissues (the expression rate was 68.27%) and in 25 out of 104 cases of para-carcinoma tissues (the expression rate was 24.03%). The expression of SATB1 in endometrial carcinoma tissues was significantly higher than that in para-carcinoma tissues (P<0.05). E-cad was positively expressed in 60 out of 104 cases of carcinoma tissues (the expression rate was 57.6%) and 95 out of 104 cases of para-carcinoma tissues (the positive expression rate was 91.3%) (P<0.05). The expression of SATB1 and E-cad in endometrial carcinoma tissues was not associated with the menopausal status or age of patients (P>0.05), but correlated with the histological grade of endometrial carcinoma, depth of tumor invasion, lymph node metastasis and tumor lymph node metastasis (TNM) staging (P<0.05). In conclusion, SATB1 and E-cad play important roles in the occurrence and development of endometrial carcinoma, which are of great significance to the potential therapeutic target and prognosis estimation of endometrial carcinoma.
