Expression of CD88 in esophageal squamous cell carcinoma and relationship with epithelial-mesenchymal transition
Purpose To study the relationshiPbetween CD88 expression and clinicopathologic features and epithelial-mesenchymal transition(EMT)in esophageal squamous cell carcinoma.Methods TCGA and TIMER database were used to analyze the expression level of CD88 in esophageal squamous cell carcinoma and adjaecnt esophageal squamous cell epithelium and its relationship with epithelial-mesenchymal transition.Par-affin specimens were collected from 199 patients with clinically diagnosed esophageal squamous cell carcinoma.Immunohisto-chemical EnVision method was used to detect the expression of CD88 and EMT-related proteins in esophageal squamous cell carcinoma and adjacent tissues,the relationship between CD88 expression and clinicopathological features,prognosis and EMT in ESCC tumors was analyzed.Results There were 86 cases with high CD88 expression and 113 cases with low CD88 expres-sion.The expression level of CD88 in esophageal squamous cell carcinoma was significantly higher than that of paracancerous tis-sue(P＜0.001).The group with high CD88 expression had lower ESCC differentiation level(P＜0.001)and higher T stage(P=0.03).The 5-year survival of patients with high CD88 ex-pression was significantly lower than that of patients with low CD88 expression(P=0.002).Cox univariate and multivariate analysis showed that CD88 expression was an independent prog-nostic factor for overall survival of patients with esophageal squa-mous cell carcinoma(P=0.013).The high expression of CD88 was negatively correlated with E-cadherin(r=-0.146,P=0.039),and positively correlated with vimentin(r=0.387,P=1.61e-08)and N-cadherin(r=0.304,P=1.3e-05).Con-clusion CD88 is highly expressed in esophageal squamous cell carcinoma.CD88 may affect the occurrence,development,in-vasion and metastasis of esophageal squamous cell carcinoma through EMT,and it might be used as a prognostic marker for e-sophageal squamous cell carcinoma patients.
