摘　　要：BACKGROUND The 5-year survival rate of patients with advanced gastric cancer remains extremely low(<15%),whereas the 5-year survival rate of patients with early gastric cancer(EGC)is>90%.Consequently,strengthening the screening of patients with EGC and precancerous lesions(PCLs)is essential.AIM To identify the value of serum pepsinogen ratio(PGR)screening for EGC and PCLs in the Shengli Oilfield Central Hospital.METHODS We first selected 385 patients with gastric lesions in the Youcheng area,deter-mining benign lesions,PCLs,and EGC in 135,123,and 127 cases,respec-tively,based on endoscopy and case diagnosis.The positive rates of pepsinogen I,pep-sinogen II and Helicobacter pylori(H.pylori)in the three groups were detected,and the PGR was calculated.Subsequently,we plotted receiver operating charac-teristic curves to analyze the screening value of PGR and H.pylori-positive rates for PCLs and EGC.RESULTS PGR expression demonstrated a decreasing trend in patients with benign lesions,PCLs,and EGC successively according to the detection results,whereas the H.pylori-positive rate was notably increased in patients with PCLs and EGC compared to those with benign lesions.The area under the curves(AUCs)of PGR,H.pylori,and their combination in differentiating patients with benign lesions from those with PCLs were 0.611,0.582,and 0.689,respectively;PGR,H.pylori,and their combination had an AUC of 0.618,0.502,and 0.618 in distinguishing PCL patients from EGC patients,respectively;the AUCs of PGR,H.pylori,and their combination in discriminating patients with benign lesions from those with EGC were 0.708,0.581,and 0.750,respectively.CONCLUSION PGR has great screening potential for patients with EGC and PCLs in the Youcheng area,and the screening efficiency is further improved by combining the H.pylori-positive rate.
