Influence of Helicobacter pylori infectoin and smoking on serum pepsinogen levels in gastric adenocarcinoma / 中国实用内科杂志

ABSTRACT

Objective To analyze the influence of Helicobacter pylori (H.pylori) and smoking on serum pepsinogen (PG) levels in gastric adenocarcinoma (GAC).Methods Serum PGⅠand PGⅡ levels were measured by using radioimmunoassay method;H.pylori infection was determined by Hp-IgG antibodies in stored serum samples by using enzyme-linked immunosorbent assay and 14C urea breath test.Results In H.pylori negative cases,the serum PGⅠmean level in current smoking GACs was significantly increased compared with those non-smoking or ever-smoking GACs (the former:t=2.709,P
