Abstract:
Objective To analyze the value of peripheral blood helper T cell 17(Th17)/regulatory T cell(Treg),programmed death receptor-1(PD-1)+CD3+,miR-146a,miR-122 and serum C-reactive protein(CRP)in the diagnosis of postoperative infection of endometrial cancer,and to explore the influencing factors of postoperative infection for endometrial cancer.Methods A total of 289 patients with endometrial cancer who underwent surgery from January 2021 to August 2024 were selected and divided into the infection group(n=53)and the non-infection group(n=236)according to the postoperative infection of the patients.Clinical data of two groups were collected and compared.The levels of Th17,Treg and PD-1+CD3+in peripheral blood of the two groups were detected by flow cytometry,and the ratio of Th17/Treg was calculated.The levels of miR-146a and miR-122 in peripheral blood of the two groups were detected by real-time fluorescence quantitative polymerase chain reaction(RT-qPCR).The serum CRP levels of the two groups were detected by enzyme-linked immunosorbent assay(ELISA),and the influencing factors of postoperative infection in endometrial cancer were analyzed by multivariate Logistic regression.The receiver operating characteristic(ROC)curve was drawn to analyze the diagnostic value of peripheral blood Th17/Treg,PD-1+CD3+,miR-146a,miR-122 and serum CRP for postoperative infection of endometrial cancer.Results Compared with the non-infection group,the infection group had higher proportions of diabetes,anemia,adjuvant chemoradiotherapy,open abdominal surgery,drainage and catheterization time≥7 d,as well as higher levels of Th17,Th17/Treg,PD-1+CD3+,miR-122,and serum CRP(P<0.01),while the levels of Treg and miR-146a in peripheral blood were lower(P<0.01).Multivariate Logistic regression analysis showed that combined diabetes,anemia,adjuvant chemoradiotherapy,open abdominal surgery,drainage and catheterization time≥7 d,peripheral blood Th17/Treg,PD-1+CD3+,miR-122 and serum CRP levels were all risk factors for postoperative infection of endometrial cancer(P<0.05,P<0.01),while miR-146a in peripheral blood was its protective factor(P<0.05).ROC curve analysis showed that the area under the curve of the combined detection of Th17/Treg,PD-1+CD3+,miR-146a,miR-122 in peripheral blood and serum CRP was higher than that of the individual detection of Th17/Treg,PD-1+CD3+,miR-146a,miR-122 and serum CRP in peripheral blood(P<0.01).Conclusion Postoperative infection of endometrial cancer is closely related to the patients'combined diabetes,anemia,adjuvant chemoradiotherapy,open surgery,and drainage and catheterization time≥7 d.Moreover,Th17/Treg,PD-1+CD3+,miR-122 in peripheral blood and serum CRP are highly expressed in patients with postoperative infection of endometrial cancer,while miR-146a in peripheral blood is expressed at a low level.The combined detection of the five has more advantages in evaluating postoperative infection of endometrial cancer.
