Background:China is an area with high incidence of gastric cancer,studies have shown that serum pepsinogen (PG) and gastrin-17 (G-17)levels can be used for gastric cancer screening. Aims:To investigate the values of serum PG and G-17 levels in screening gastric precancerous lesion and gastric cancer. Methods:A total of 211 patients with gastroduodenal disease diagnosed by endoscopy and biopsy from March 2016 to October 2016 at the First Affiliated Hospital of Soochow University were enrolled,and 67 healthy subjects were served as controls. Serum levels of PGⅠ,PGⅡ,G-17 and Hp-IgG antibodies were determined by ELISA. Results:Compared with control group,PGⅠ level and PGR were significantly decreased in atrophic gastritis group (P < 0. 01);serum PGⅠ level and PGR were significantly decreased, and G-17 level was significantly increased in low grade intraepithelial neoplasia group,high grade intraepithelial neoplasia group and gastric cancer group (P < 0. 01). ROC curve showed that the best cutoff values of PGⅠ,PGR and G-17 for diagnosing gastric cancer and gastric precancerous lesion were 74. 74 ng/ mL (sensitivity 88. 3%,specificity 78. 0%), 6. 59 (sensitivity 87. 0%,specificity 73. 8%),13. 02 pmol/ L (sensitivity 54. 2%,specificity 84. 4%),respectively. PGR and G-17 were the independent predictors of gastric cancer and gastric precancerous lesion. The sensitivity and specificity of combined detection of PGⅠ,PGR and G-17 for diagnosing gastric precancerous lesion and gastric cancer were 89. 9% and 84. 4%,respectively. Conclusions:Serum PGⅠ,PGR and G-17 may be used as indicators of gastric cancer and gastric precancerous lesion screening. PG combined with G-17 for diagnosing gastric cancer and gastric precancerous lesion is more sensitive and specific than using serum PG or G-17 alone.
