Abstract:
Objective:To study the expression of FOXP3 in gastric cancer and its prognostic significance.Methods:One hundred and six specimens of gastric adenocarcinoma confirmed by pathology from the Department of Gastrointestinal Surgery of the Second People′s Hospital of Lianyungang in Jan. 2005 to Dec. 2015 were selected as the observation group and 85 normal para-cancer tissues as the control group. The expression of FOXP3 in 106 cases of gastric cancer was detected by tissue microarray and immunohistochemical technology. Cox regression model was used to analyze the correlation between survival data and prognosis, and Kaplan-Meiers was used to analyze the relationship between FOXP3 expression and the prognosis of gastric cancer patients.Results:The positive rate of FOXP3 expression was 53.8% (57/106) in gastric cancer tissues and 28.2% (24/85) in paraneoplastic tissues, and the difference was statistically significant ( χ2=12.597, P<0.001). The level of FOXP3 expression in gastric cancer tissues was significantly correlated with the TNM stage of patients′ tumors ( χ2=4.402, P<0.05). Single-factor Cox survival analysis showed that age, tumor pathological grade, tumor size, whether it invaded lymph nodes, TNM stage, FOXP3 expression level and prognosis were correlated.Kaplan-Meier survival analysis showed that the survival rate of tumor cell FOXP3-positive group was lower than that of FOXP3-negative group; in the subgroup type, among the subgroups, any age group, any sex group, stage Ⅲ and Ⅳ tumor cell subgroups, low- and undifferentiated groups, tumor size <16 cm 3 group, and tumor cell FOXP3 expression-positive group invading lymph nodes had lower survival than tumor cell FOXP3 expression-negative group. Conclusions:The expression of FOXP3 is up-regulated in gastric cancer. The expression of FOXP3 in gastric cancer may be a prognostic factor, and the positive expression of FOXP3 may indicate a worse prognosis.
