Abstract
OBJECTIVES We explored whether the association between vitamin B2 and colorectal cancer (CRC) risk could be modified by the MTRR rs1801394 and MTR rs1805087 genetic polymorphisms and examined whether the interaction effects are sex-specific.
METHODS We performed a case‒control study involving 1,420 CRC patients and 2,840 controls from the Korea National Cancer Center. Dietary vitamin B2 intake was assessed using a semiquantitative food frequency questionnaire, and the association with CRC was evaluated. Genotyping was performed using an Illumina MEGA-Expanded Array. For gene-nutrient interaction analysis, pre-matched (1,081 patients and 2,025 controls) and matched (1,081 patients and 1,081 controls) subsets were included. Unconditional and conditional logistic regression models were used to calculate odds ratios (ORs) and 95% confidence intervals (CIs).
RESULTS A higher intake of vitamin B2 was associated with a significantly lower CRC risk (OR=0.65; 95% CI, 0.51-0.82; p<0.001). Carriers of at least 1 minor allele of MTRR rs1801394 showed a significantly higher CRC risk (OR=1.43; 95% CI, 1.12-1.83). Men homozygous for the major allele (A) of MTRR rs1801394 and who had a higher intake of vitamin B2 had a significantly lower CRC risk (OR=0.31; 95% CI, 0.18-0.54; p-interaction=0.02). In MTR rs1805087, men homozygous for the major allele (A) and who had a higher vitamin B2 intake had a significantly lower CRC risk (OR=0.38; 95% CI, 0.25-0.60; p-interaction<0.001).
CONCLUSIONS The MTRR rs1801394 and MTR rs1805087 genetic polymorphisms may modify the association between vitamin B2 and CRC risk, particularly in men. However, further studies are warranted to confirm these interaction results.

Abstract
OBJECTIVES Previous human trials have not supported the anticarcinogenic effect of vitamin E despite biological plausibility and considerable epidemiological evidence. A possible explanation for this inconsistency is the interactive effect of the catechol-O-methyltransferase (COMT) gene and supplemental vitamin E on cancer. We examined whether a COMT gene variant modulates the effect of dietary vitamin E intake on colorectal cancer (CRC) risk.
METHODS In this case-control study of Korean adults (975 cases and 975 age- and sex-matched controls), dietary vitamin E density (mg/1,000 kcal) was measured using a semiquantitative food frequency questionnaire, COMT single nucleotide polymorphism (SNP) rs740603 (A>G) was genotyped, and CRC was verified histologically. We estimated odds ratios (ORs) and 95% confidence intervals (CIs) using unconditional logistic regression models with adjustments for potential confounders.
RESULTS Higher vitamin E density was associated with a lower risk of CRC (highest vs. lowest quartiles: OR, 0.72; 95% CI, 0.55 to 0.96; p-for-trend=0.002). When stratified by COMT SNP rs740603 genotype, the inverse association between vitamin E density and CRC risk was confined to those with at least 1 A allele (≥median vs. <median: OR, 0.63; 95% CI, 0.51 to 0.78). The interaction between rs740603 and vitamin E density was significant (p-for-interaction=0.020). No direct association was observed between COMT SNP rs740603 and CRC risk (OR, 1.08; 95% CI, 0.83 to 1.41).
CONCLUSIONS Our findings support a role for a genetic polymorphism in COMT in modifying the association between dietary vitamin E intake and CRC.

Key Message
In this case-control study of Korean adults, we examined whether a polymorphism in the catechol-O-methyltransferase (COMT) gene modulates the effect of dietary vitamin E intake on colorectal cancer risk. Our results suggest that the inverse association between vitamin E density and colorectal cancer risk is confined to carriers of the COMT rs740603 A allele. The findings of our study support the interactive effect of the COMT gene and vitamin E intake on colorectal cancer risk.

Abstract
OBJECTIVES Dietary and lifestyle exposures may affect the risk of colorectal cancer (CRC) by promoting chronic inflammation. Therefore, we assessed the separate and joint associations of dietary and lifestyle inflammation scores (DIS and LIS, respectively) with CRC.
METHODS Data from 919 pathologically confirmed CRC cases and 1,846 age- and sex-matched controls recruited at the National Cancer Center Korea were analyzed. We calculated the DIS and LIS, which characterize the collective contributions of 19 dietary and 4 lifestyle factors, respectively, to systemic inflammation by applying weights based on high-sensitivity C-reactive protein. A higher score represented a higher balance of pro- to anti-inflammatory exposures. Unconditional logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for CRC risk compared across the DIS and LIS tertile categories, with the lowest tertile as the reference group.
RESULTS The highest DIS tertile had significantly increased odds of having CRC (OR, 2.65; 95% CI, 2.10 to 3.36), and the odds increased with increasing DIS. The highest LIS tertile group had 1.28-fold higher odds of having CRC (95% CI, 1.03 to 1.58). In the cross-classification analysis, the odds of having CRC increased as the DIS and LIS jointly increased until the DIS reached the highest tertile, where the risk was very high (3-fold or more) regardless of the LIS.
CONCLUSIONS In conclusion, a higher balance of pro-inflammatory relative to anti-inflammatory dietary and lifestyle factors, especially dietary factors, was associated with higher CRC risk among Korean adults.

Key Message
Dietary inflammation score (DIS) and lifestyle inflammation score (LIS) quantify the collective effect of dietary and lifestyle factors, respectively, on systemic inflammation. In this case-control study, we assessed the associations of DIS and LIS with colorectal cancer risk among Korean adults. Our results suggest that a higher balance of pro-to anti-inflammatory dietary and lifestyle factors may be associated with higher risk for colorectal cancer. The findings from our study support that reducing inflammation through dietary or lifestyle changes could potentially reduce the risk for colorectal cancer.

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.
