ABSTRACT
Objective To study the relationships of Helicobacter pylori (Hp) infection and genetic polymorphisms of glutathione s-transferase P1 (GSTP1) with gastric cancer (GC). Methods The 98 patients with GC and 149 controls with normal finding at endoscopy were enrolled for this study. The rapid urease test (RUT), 13C- urea breath test (13C-UBT) and Giemsa staining of biopsy samples were used to check Hp infection. PCR-based restriction fragment length polymorphisms (PCR-RFLP) was used to detect GSTP1 genotype. Results The rate of Hp infection was higher in GC group than in control group (54.1% vs. 40.9%, x2 =4.11, P<0. 05). The risk of GC would significantly increase in the GSTP1 homozygous mutant gene (MM) group with Hp infection (OR=5.44, 95%CI 1. 26-26. 79, x2=7.13, P<0.05). Conclusions Hp infection and GSTP1 genetic polymorphisms are associated with gastric cancer risk in the elderly.
