Abstract:
Objective To investigate the clinical value of serum pepsinogen(PG)Ⅰ,Ⅱ and gastrin-17(G-17)levels in early di-agnosis for atrophic gastritis and gastric cancer.Methods The study was performed on a case-control trial,and 430 subjects were recruited.Each of them underwent endoscopy biopsies before serum tests were performed.These patients were further divided into three groups based on endoscopic and histological findings:160 non-atrophic gastritis group,118 atrophic gastri-tis group and 152 gastric cancer group.Serum samples of PGⅠ,PGⅡ and G-17 were analyzed by enzyme-linked immunosor-bent assay(ELSIA),and calculated the values of PGⅠ/PGⅡratio.Results Compared with the non-atrophic gastritis group, serum PGⅠ and G-1 7 values in atrophic gastritis and serum PGⅠ,PGⅡ,PGⅠ/PGⅡratio and G-1 7 values in gastric cancer group decreased significantly (P<0.05);compared with the atrophic gastritis group,serum PGⅠ and G-17 values in gastric cancer group decreased significantly (P<0.05).By using receiver operating characteristic curves (ROC),the cut-off points of PGⅠ84.706μg/L,PGⅡ 10.873μg/L,PGⅠ/PGⅡ ratio 11.008 and G-178.265 pg/L in atrophic gastritis group,PGⅠ65.145μg/L,PGⅡ 10.089μg/L,PGⅠ/PGⅡ ratio 6.375 and G-17 4.971 pg/L in gastric cancer group.Conclusion Low serum PGⅠ,PGⅡ,PGⅠ/PGⅡ ratio and G-1 7 values are biomarkers of atrophic gastritis and gastric cancer and valuable for the early diagnosis of gastric cancer.
