Alcohol consumption and the risk of renal cancers

What’s new? Previous studies have indicated that environmental or lifestyle factors may be involved in the etiology of renal cancer, and that moderate alcohol consumption may reduce the risk of this type of cancer. In this very large European study (nearly 500,000 subjects), the authors found that, indeed, total alcohol consumption was inversely associated with renal cancer overall (for all subsites combined), and also with cancers of the renal parenchyma.

Epidemiology

Epidemiologic studies have reported that moderate alcohol consumption is inversely associated with the risk of renal cancer. However, there is no information available on the associations in renal cancer subsites. From 1992 through to 2010, 477,325 men and women in the European Prospective Investigation into Cancer and Nutrition cohort were followed for incident renal cancers (n 5 931). Baseline and lifetime alcohol consumption was assessed by country-specific, validated dietary questionnaires. Information on past alcohol consumption was collected by lifestyle questionnaires. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated from Cox proportional hazard models. In multivariate analysis, total alcohol consumption at baseline was inversely associated with renal cancer; the HR and 95% CI for the increasing categories of total alcohol consumption at recruitment versus the light drinkers category were 0.78 (0.62–0.99), 0.82 (0.64–1.04), 0.70 (0.55–0.90), 0.91 (0.63–1.30), respectively, (ptrend 5 0.001). A similar relationship was observed for average lifetime alcohol consumption and for all renal cancer subsites combined or for renal parenchyma subsite. The trend was not observed in hypertensive individuals and not significant in smokers. In conclusion, moderate alcohol consumption was associated with a decreased risk of renal cancer.

Renal cancers consist of malignant tumors of renal parenchyma and renal pelvis. Adenocarcinoma of renal parenchyma [referred to as renal cell carcinoma (RCC)] accounts for over 90% of renal cancers while nearly all cancers arising in renal pelvis are of the transitional cell type and comprise 0–6 (men) >0–3 (women)

hypertension and diabetes showing 31.2 and 7.2% in men and 25.9 and 4.6% in women, respectively. The nonlinear regression analyses for baseline and lifetime alcohol consumption and renal cancer risk for men and women combined are presented in Figures 1 and 2. These nonparametric regression analyses showed evidence of nonlinearity in the association between alcohol consumption and renal cancer risk in the multivariable model for both baseline (p values 5 0.113) and lifetime alcohol consumption (p-value 5 0.035). For both baseline and lifetime alcohol consumption, a linear inverse association was observed in participants with alcohol consumption lower than 10 g/day, this relationship became flat above 10 g/ day. Overall, total baseline and lifetime alcohol consumption were inversely associated with risk of renal cancer (Table 3). In the multivariate model, decreased risks (ptrend 5 0.001) were observed between baseline alcohol consumption and renal cancers combined, compared with light drinkers. This inverse trend remained significant when estimated for drinkers only (ptrend 5 0.047). Similar HRs were observed when diabetes and physical activity were added as covariates to the multivariable model (data not shown). The inverse association for baseline alcohol consumption was mostly driven by the association in renal parenchyma (ptrend 5 0.026) where lower HRs were observed than in renal pelvis. The competing risk analysis provided very similar HRs (Supporting Information Table S1). In addition, similar trends for inverse association have been found in different geographical regions (Supporting Information Table S2). We further assessed associations for specific alcoholic beverages, alcohol consumption from beer, wine, liquor and spirits for men and women combined (Table 3). Among all cohort participants 18% of men and 46% of women were nonbeer drinkers, 13% of men and 20% of women were non-wine drinkers and 28% of men and 56% of women were not drinking spirits and liquor beverages. On average, men had a higher use of alcohol from each beverage for both consumption at recruitment and lifetime. The median consumption for beverages (in grams of alcohol from beverage per day) at recruitment was: beer 4.8 g/d for men and 0.6 g/d for women, wine 5.1 g/d for men and 3.7 g/d for women, liquor and spirits 1.2 g/d for men and 0.4 g/d for women. One type of alcoholic beverage alone was not associated with the risk of all renal cancer subsites combined, when adjusted for other types of alcoholic beverages. Looking at these associations separately by sex did not show strong associations (Supporting Information Tables S3 and S4). There was however a significant inverse association with lifetime consumption of alcohol from liquor and spirits among men (ptrend 5 0.030). A significant inverse association was observed in wine only drinkers, particularly in women where a HR of 0.51 (95% CI 0.31–0.84) was observed

(Supporting Information Table S5). Beer only drinkers also showed an inverse association with renal cancer risk, although not significantly. Table 4 presents the HRs for renal cancer and alcohol consumption at baseline stratified by sex, history of hypertension, smoking status, diabetes and BMI. We found an inverse association between total alcohol consumption and renal cancer in both sexes with stronger effects in women (men: ptrend 5 0.057; women: ptrend 5 0.003). Interestingly, a lower risk of renal cancer was found for participants who declared no history of hypertension. These results were of similar magnitude for lifetime consumption (Supporting Information Table S6). In addition, the associations between baseline and average lifetime alcohol consumption were not modified by sex, hypertension, smoking status, diabetes and BMI as evaluated by likelihood ratio test based on models with and without interaction term. Nonsignificant interactions were observed for alcohol consumption and all variables (all pinteraction > 0.05).

time. We found that alcohol consumption was inversely associated with the risk of renal cancer in men and women. The study supports previous evidence of an inverse association between alcohol consumption and the risk of renal cancers. In addition, this study evaluated alcohol consumption in different renal cancer subsites including renal parenchyma and renal pelvis showing significant inverse associations of moderate alcohol consumption and cancers of renal parenchyma. Interestingly, our data also revealed that individuals with self-reported hypertension did not present lower risk of renal cancers combined in relation to alcohol consumption. Moderate alcohol consumption was inversely associated with renal cancer in our study and supports previous reports of case–control and prospective studies that have shown an inverse association between alcohol consumption and risk of RCC.15–25,39,40 We did not find any clear dose response relationship for the main analyses. The inverse association was observed for all renal cancer subsites combined and subsite of renal parenchyma. However, other cohort11–14,41 and case-control studies8–10 have reported no association. These dissimilarities could be due to different methodologies used to study alcohol consumption and renal cancer risk, quality of data, sample size and varying categories of alcohol consumption.

Discussion In this large prospective European cohort study, we assessed two measures of alcohol consumption. These included alcohol consumption at recruitment, which evaluates recent consumption only as well as alcohol consumption over life-

Tests for trend were performed by ordinal coding of the variable under consideration. The significance of interactions was assessed using likelihood ratio tests based on the models with and without the interaction terms.

Alcohol consumption and the risk of renal cancers in the European prospective investigation into cancer and nutrition (EPIC).

Epidemiologic studies have reported that moderate alcohol consumption is inversely associated with the risk of renal cancer. However, there is no info...
