Objective The aim of this study was to investigate the expression of IL-23(IL-23)in breast cancer and its cor-relation with clinicopathological characteristics.Methods The tumor tissues and adjacent tissues of 100 patients with breast cancer diagnosed in Nanchong Central Hospital from January 2020 to December 2020 were collected.Immunohistochemistry and Real-Time PCR were used to determine the expression of IL-23 protein and mRNA in the two groups of tissues.The expression of IL-23 protein and mRNA in breast cancer tissues and adjacent tissues were compared,and the relationship between IL-23 expression and the clini-copathological characteristics of breast cancer was analyzed.Results IL-23 protein was mainly expressed in the membrane and cyto-plasm of breast cancer cells.The expression of IL-23 protein and mRNA in breast cancer tissues were higher than those in adjacent tissues(P<0.001).The expression of IL-23 protein and mRNA was positively correlated with the histological grade,T grade,clinical stage and Ki-67 expression of breast cancer,negatively correlated with the expression of ER and PR(P<0.05),and was not related to neurovascular invasion,age and HER-2 expression in breast cancer(P>0.05).Conclusion IL-23 may participate in the progres-sion of breast cancer,and its expression is closely related to ER,PR,Ki-67 and other prognostic indicators,suggesting that its expres-sion may be related to the prognosis,but it needs further experimental verification.

Objective To analyse the effect of baseline serum vascular endothelial growth factor(VEGF)level on clinical factors,pathological features and prognosis of patients with non-triple-negative breast cancer.Methods A total of 120 patients with non-triple-negative breast cancer admitted to the hospital from January 2019 to December 2020 were selected as the study objects.According to the TNM stage of the tumor,the stud-y objects were divided into 80 patients with TNM stage Ⅰ and Ⅱ(group A)and 40 patients with TNM stageⅢ(group B).Serum VEGF levels,clinical factors and pathological features were compared between the two groups.Receiver operating characteristic(ROC)curve was used to analyze the optimal cut-off value of serum VEGF level in predicting stage Ⅲ breast cancer.Survival curves for overall survival and disease-free survival were plotted using the Kaplan-Meier method,and comparisons were made using the Log-rank test.The effects of baseline serum VEGF levels on overall survival and disease-free survival in non-triple-negative breast cancer were investigated by multivariate Cox regression model.Results Serum VEGF,D-dimer,fibrinogen(FIB),fi-brin degradation products(FDP),cancer antigen 125(CA-125)and cancer antigen 15-3(CA15-3)in group B were significantly different from those in group A(P＜0.05).ROC curve analysis showed that the area under the curve of serum VEGF in TNM stage Ⅲ of non-triple-negative breast cancer was 0.875,95％CI(0.802-0.948),P＜0.001.The levels of D-dimer,FIB,FDP,CA-125 and CA15-3 in serum VEGF≥180.40 pg/mL patients were higher than those in serum VEGF＜180.40pg/mL patients,and the differences were statistically significant(P＜0.05).In patients with serum VEGF＜180.40 pg/mL,the proportion of tumor T1 stage,tumor N0 and N1 stage,TNM stage Ⅰ/Ⅱ,and Luminal type A were higher than those with serum VEGF≥180.40 pg/mL patients,and the differences were statistically significant(P＜0.05).The disease-free survival rate of serum VEGF＜180.40 pg/mL patients was significantly higher than that of serum VEGF≥180.40 pg/mL patients,and the difference was statistically significant(P＜0.001).After correction,VEGF≥180.40 pg/mL was a risk factor for recurrence and metastasis of non-triple-negative breast cancer[HR=2.563,95％CI(1.772-3.708),P＜0.001].Conclusion High baseline VEGF levels are associated with progression of non-triple-negative breast cancer and are an influential factor in its prognosis.
