Abstract:
Objective:To investigate the correlation of programmed death receptor-1(PD-1)and V-domain im-munoglobulin suppressor of T-cell activation(VISTA)expression with the imbalance of helper T lymphocytes(Th)1/Th2,Th17/regulatory T cells(Treg),and Th22 in the microenvironment of endometrial cancer(EC).Methods:From March 1,2020 to June 30,2023,94 patients with EC(EC group),94 patients with atypical hyperplasia of the endometrium(AH),and 94 controls without uterine and endometrial diseases such as EC and AH(control group)were selected for treatment at the Tangshan Maternal and Child Health Hospital.The expression of PD-1 and VIS-TA in various tissues and the levels of Th1/Th2,Th17/Treg,and Th22 in the endometrial microenvironment were compared.Pearson analysis was used to investigate the correlation between the expression of PD-1 and VISTA in tissues and the imbalance of Th1/Th2,Th17/Treg,and Th22 in the EC microenvironment.The positive expression of PD-1 and VISTA in tissues of patients with different pathological characteristics was also compared.Results:①The expression of PD-1 and VISTA was higher in EC group and AH group than that in the control group,and high-er in EC group than AH group,with statistically significant differences(P＜0.05).In both EC group and AH group,Th1/Th2 and Th17/Treg levels in the microenvironment were lower than those in the control group,while Th22 level was higher.EC group showed lower Th1/Th2 and Th17/Treg levels but higher Th22 level than AH group,with statistically significant differences(P＜0.05).②No correlation was found between the expression of PD-1 and VISTA and the Th1/Th2,Th17/Treg,and Th22 in the microenvironment in control group(P＞0.05).In AH group and EC group,the expression of PD-1 and VISTA was negatively correlated with the Th1/Th2 and Th17/Treg lev-els in the microenvironment(r＜0,P＜0.05),but positively correlated with Th22 level in the microenvironment(r＞0,P＜0.05).③In EC patients,the expression of PD-1 was related with clinical stage,invasion depth,and lymph node metastasis(P＜0.05);VISTA expression was related with clinical stage and lymph node metastasis(P＜0.05).Conclusions:The high expression of PD-1 and VISTA in EC is closely associated with the imbalance of Th1/Th2,Th17/Treg,and Th22 in the tumor microenvironment,as well as the tumor ivasiveness.The dual inhibi-tion strategy targeting PD-1 and VISTA immune checkpoints may offer a novel approach for EC treatment.
