Clinical significance of FOXP3 expression in gastric cancer cells / 中国医师杂志

ABSTRACT

Objective To explore the expression of forkhead box protein 3 (FOXP3) in gastric cancer cells,and its relationship with clinicpathological characteristics and prognosis of gastric cancer patients.Methods The expression profile of FOXP3 in 111 gastric adenocarcinoma tissues and 20 normal gastric mucosa were detected with immunohistochemistry,statistical analysis combined with clinical data of patients with gastric cancer.Results Positive staining of FOXP3 was mainly located in the nucleus of gastric adenocarcinoma cells with the positive rate of 42.3％ (47/112).In the normal gastric tissue,the positive rate of FOXP3 was 0％ (0/20).There were significant difference (x2 =13.207,P ＜0.05) when comparison was made between gastric adenocarcinoma and normal gastric tissue groups.Comparison of FOXP3 positive rate between gastric adenocarcinoma patients and its histological subtype (tumor size,depth of invasion,and clinical stage) showed significant difference (P ＜0.05),but (sex,age,and staging of tumor node metastasis (TNM),lympho node metastasis and differentiation) showed no significant difference (P ＞ 0.05).In the survival analysis,there was no significance in survival rate between the FOXP3 positive group and FOXP3 negative group either (P ＞ 0.05).Conclusions The FOXP3 were expressed in the human gastric cancer specimens.To a certain extent,FOXP3 was involved in the development of gastric adenocarcinoma and related to the degree of malignancy,but is not related to the prognosis of gastric cancer.
