Abstract

Background

This study aimed to examine the associations of a RUNX3 T/A polymorphism at exon 1 (Asn18Ile) (rs6672420) and another RUNX3 intronic T/A polymorphism (rs760805) with the risk of gastric cancer together with the risk of H. pylori seropositivity and gastric atrophy in Japanese people.

Methods

Study subjects were 583 histologically diagnosed gastric cancer patients and age- and sex-frequency-matched 1,742 control outpatients (among whom 1,637 subjects were eligible for the analyses), who visited Aichi Cancer Center Hospital from 2001 to 2005. Serum pepsinogens were measured to evaluate gastric atrophy.

Results

There was no significant association between the RUNX3 polymorphisms and the seropositivity. Among H. pylori seropositive subjects, we found a significant association between RUNX3 rs760805 polymorphism and the risk of gastric atrophy with the age- and sex-adjusted OR of 1.51 (95% CI 1.11–2.05, P = 0.008) in T/A, 1.59 (95% CI 1.08–2.33, P = 0.019) in A/A, and 1.53 (95% CI 1.14–2.05, P = 0.004) in T/A + A/A, compared with T/T genotype. We found no statistically significant associations between RUNX3 rs6672420 polymorphism and risk of gastric atrophy, nor between these two RUNX3 polymorphisms and the risk of gastric cancer relative to the subjects with gastric atrophy.

Conclusions

Our study results revealed that the RUNX3 intronic T/A polymorphism (rs760805) might modulate the risk of gastric atrophy among H. pylori seropositive subjects, and the RUNX3 T/A polymorphism at exon 1 (rs6672420) had little influence on the risks of H. pylori infection, gastric atrophy or gastric cancer in Japanese people. Further investigation is required to verify our findings.

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
