Abstract
OBJECTIVES
Mercury can stimulate immune responses through T helper 17 (Th17). The gene <i>IL23R</i> is a key factor in Th17 function, which may also contribute to digestive tract diseases. The aim of this study was to identify the associations between dietary mercury and gastric cancer (GC) and to investigate whether the <i>IL23R</i> rs10889677 polymorphism modifies those associations.
METHODS
This case-control study included 377 patients with GC and 756 healthy controls. Dietary mercury intake (total mercury and methylmercury) was assessed using a dietary heavy metal database incorporated into the food frequency questionnaire. <i>IL23R</i> genetic polymorphism rs10889677 (A>C) was genotyped. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using unconditional logistic regression models with adjustments for potential confounders.
RESULTS
A higher dietary methylmercury intake was associated with an elevated risk of GC (OR for the highest vs. lowest tertile [T<sub>3</sub> vs. T<sub>1</sub>], 2.02; 95% CI, 1.41 to 2.91; p for trend <0.001). The <i>IL23R</i> rs10889677 reduced the risk of GC in individuals who carried at least 1 minor allele (OR, 0.62; 95% CI, 0.46 to 0.83; p=0.001; AC/CC vs. AA). Individuals with a C allele exhibited a lower susceptibility to GC through methylmercury intake than those with the AA genotype (OR for the T<sub>3</sub> of methylmercury and AA carriers, 2.93; 95% CI, 1.77 to 4.87; and OR for the T<sub>3</sub> of methylmercury and AC/CC genotype, 1.30; 95% CI, 0.76 to 2.21; p-interaction=0.013).
CONCLUSIONS
Our findings suggest that a genetic polymorphism, rs10889677 in <i>IL23R</i>, plays a role in modifying the association between dietary methylmercury intake and the risk of GC.
Summary
Korean summary
본 연구는 식이 수은과 위암 간의 연관성을 탐색하고, microRNA-lethal-7의 예측된 결합 부위 내에 위치한 IL23R rs10889677 다형성이 이러한 연관성에 영향을 미칠 수 있는지 규명하고자 합니다. 식이 메틸수은 섭취량에 비례하여 위암 발생 위험이 증가하는 경향이 확인되었고, IL23R rs10889677 다형성은 식이 메틸수은으로 의한 위암 발생 위험을 조절하는 인자로 작용할 수 있음을 시사합니다.
Key Message
This study aimed to investigate the associations between dietary mercury and gastric cancer (GC) and to determine whether the IL23R rs10889677 polymorphism, located within a predicted binding site for microRNA-lethal-7, may modify these associations. A higher dietary methylmercury intake was associated with an increased risk of GC, while the IL23R rs10889677 polymorphism may modify the detrimental effect of dietary methylmercury on gastric carcinogenesis.

Abstract
OBJECTIVES
Gastric carcinogenesis is linked to oxidative stress from both exogenous and endogenous exposures. This study aimed to determine the association between the risk of gastric cancer and the oxidative balance score (OBS), which comprises antioxidant and pro-oxidant factors, including diet and lifestyle.
METHODS
For this hospital-based case-control study, 808 controls and 404 patients with gastric cancer who had clinical records indicating <i>Helicobacter pylori</i> infection and the histological subtype of cancer were recruited. The OBS was determined based on diet and lifestyle factors obtained from a 106-item semiquantitative food frequency questionnaire and a constructed questionnaire. Logistic regression analysis was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs).
RESULTS
A higher OBS was associated with a reduced gastric cancer risk (OR, 0.49; 95% CI <sub>T3 vs. T1,</sub> 0.33 to 0.71; p for trend <0.001). In a subgroup analysis, antioxidant factors showed inverse associations with gastric cancer risk (OR, 0.53; 95% CI <sub>T3 vs. T1,</sub> 0.35 to 0.79; p for trend=0.003). A stronger association with antioxidant factors was observed in patients with intestinal gastric cancer (OR, 0.34; 95% CI <sub>T3 vs. T1,</sub> 0.19 to 0.62; p for trend<0.001) and those with <i>H. pylori</i> infection (OR, 0.57; 95% CI <sub>T3 vs. T1,</sub> 0.37 to 0.88; p for trend=0.014).
CONCLUSIONS
A predominance of antioxidant factors compared to pro-oxidant factors from diet and lifestyle reduced the risk of gastric cancer. The combined effect of oxidative stress, which involves an altered balance between antioxidants and pro-oxidants, is important for modulating the risk of gastric cancer.

본 연구에서는 한국인 암 발생의 상위권을 차지하는 위암 발병률에 대해 영양소, 식품, 생활습관 등 항산화와 산화촉진 요인으로 구성된 산화 균형 점수(Oxidative Balance Score)와의 연관성을 비교 분석하였습니다. 산화촉진 요인에 비해 항산화 관련 요인에서 위암 발생의 위험이 유의하게 감소함을 나타냈습니다.
Key Message
The aim of this study was to determine the association between the risk of gastric cancer and the oxidative balance score comprising antioxidant and pro-oxidants factors, including diet and lifestyle. We found that predominantly antioxidants from diet and lifestyle, in contrast to pro-oxidants, reduce the risk of gastric cancer.
