Abstract: Objective To investigate the expression of SOX2 in gastric carcinoma and to analyze its relationship with clinicopathological features.Methods Immunohistochemistry method was used to detect the level of SOX2 in 67 cases of gastric carcinoma group and 30 cases of normal gastric mucosa group.Results The positive expression rate of SOX2 in gastric carcinoma group (52.24 ％) was obviously lower than that in normal gastric mucosa group (93.33 ％) (x2 =16.326,P ＜ 0.01).The SOX2 expression was significantly correlated with differentiation,the depth of invasion,lymph node metastasis and TNM stage of the tumor (all P ＜ 0.05).Conclusions The low expression of SOX2 may contribute to the early carcinogenesis of gastric carcinoma,and the expression level of SOX2 is closely related with lymph node metastasis and TNM stage.The expression level of SOX2 is a useful marker for predicting the prognosis of gastric carcinoma.
