Abstract

Recent evidence suggested a weak relationship between alcohol consumption and pancreatic cancer (PC) risk. In our study, the association between lifetime and baseline alcohol intakes and the risk of PC was evaluated, including the type of alcoholic beverages and potential interaction with smoking. Within the European Prospective Investigation into Cancer and Nutrition (EPIC) study, 1,283 incident PC (57% women) were diagnosed from 476,106 cancer-free participants, followed up for 14 years. Amounts of lifetime and baseline alcohol were estimated through lifestyle and dietary questionnaires, respectively. Cox proportional hazard models with age as primary time variable were used to estimate PC hazard ratios (HR) and their 95% confidence interval (CI). Alcohol intake was positively associated with PC risk in men. Associations were mainly driven by extreme alcohol levels, with HRs comparing heavy drinkers (>60 g/day) to the reference category (0.1-4.9 g/day) equal to 1.77 (95% CI: 1.06, 2.95) and 1.63 (95% CI: 1.16, 2.29) for lifetime and baseline alcohol, respectively. Baseline alcohol intakes from beer (>40 g/day) and spirits/liquors (>10 g/day) showed HRs equal to 1.58 (95% CI: 1.07, 2.34) and 1.41 (95% CI: 1.03, 1.94), respectively, compared to the reference category (0.1-2.9 g/day). In women, HR estimates did not reach statistically significance. The alcohol and PC risk association was not modified by smoking status. Findings from a large prospective study suggest that baseline and lifetime alcohol intakes were positively associated with PC risk, with more apparent risk estimates for beer and spirits/liquors than wine intake.

摘要

近期有证据表明,饮酒与胰腺癌(PC)风险之间存在微弱关联。在我们的研究中,评估了终生和基线饮酒量与 PC 风险之间的关系,包括酒精饮料的类型以及与吸烟的潜在相互作用。在欧洲癌症与营养前瞻性调查(EPIC)研究中,从 476106 名无癌症的参与者中诊断出了 1283 例新确诊的 PC(57%为女性),随访了 14 年。通过生活方式和饮食问卷分别估计了终生和基线饮酒量。使用以年龄为主要时间变量的 Cox 比例风险模型来估计 PC 的危险比(HR)及其 95%置信区间(CI)。饮酒与男性 PC 风险呈正相关。这些关联主要归因于极端饮酒水平,与参考类别(0.1-4.9 g/天)相比,重度饮酒者(>60 g/天)的 HR 分别等于 1.77(95%CI:1.06,2.95)和 1.63(95%CI:1.16,2.29),分别用于终生和基线饮酒。与参考类别(0.1-2.9 g/天)相比,啤酒(>40 g/天)和烈酒/利口酒(>10 g/天)的基线饮酒量的 HR 分别为 1.58(95%CI:1.07,2.34)和 1.41(95%CI:1.03,1.94)。在女性中,HR 估计值没有达到统计学意义。饮酒与 PC 风险之间的关联不受吸烟状况的影响。来自大型前瞻性研究的结果表明,基线和终生饮酒量与 PC 风险呈正相关,与葡萄酒相比,啤酒和烈酒/利口酒的风险估计值更为明显。
