Abstract:
Objective To investigate the expression levels and clinical significance of B7 homolog 3(B7-H3),peroxiredoxin 1(PRDX1),and thioredoxin(TRX)in the serum and tissues of patients with ulcerative colitis(UC)and UC-associated colorectal cancer(UC-CRC).Methods A total of 108 patients with UC who underwent examination in our hospital between January 2019 and December 2023 were enrolled in the UC group.Additionally,108 patients with UC-CRC who were examined in our hospital were included in the UC-CRC group.Furthermore,108 individuals without any abnormalities detected during colonoscopy were recruited as the control group.The serum levels of B7-H3,PRDX1,and TRX were quantified using enzyme-linked immunosorbent assay(ELISA).The expression of B7-H3,PRDX1,and TRX in tissues from UC-CRC and UC patients was assessed by immunohis-tochemistry.The diagnostic performance of serum B7-H3,PRDX1,and TRX levels for UC-CRC was evaluated by constructing receiver operating characteristic(ROC)curves.Results Compared with the control group,the serum expression levels of B7-H3,PRDX1,and TRX in both the UC group and the UC-CRC group were significantly elevated in sequence(P<0.05).In comparison to the resting UC group,the serum expression levels of B7-H3,PRDX1,and TRX in the episodic UC group also increased significantly(P<0.05).Furthermore,compared with UC patients,the positive expression rates of B7-H3,PRDX1,and TRX in the tissues of UC-CRC patients were markedly higher(P<0.05).The combination of serum B7-H3,PRDX1,and TRX demonstrated the highest AUC for diagnosing UC-CRC patients,outperforming the individual diagnostic performance of each biomarker(Z combination-B7-H3=2.829,P=0.005,Z combination-PRDX1=2.544,P=0.011,Z combination-TRX=3.673,P<0.001).Conclusion B7-H3,PRDX1,and TRX are significantly overexpressed in both the serum and tissues of UC-CRC patients,and their combined evaluation holds potential as a diagnostic tool for detecting the development of UC-CRC.
