Abstract

Background: Pancreatic cancer (PC) is a serious and rapidly progressing malignancy. Identifying risk factors including dietary elements is important to develop preventive strategies. This study focused on possible links between diet and PC. Methods: We conducted a case-control study including all PC patients diagnosed at Minia Cancer Center and controls from general population from June 2014 to December 2015. Dietary data were collected directly through personal interviews. Principal component analysis (PCA) was performed to identify dietary groups. The data were analyzed using crude odds ratios (ORs) and multivariable logistic regression with adjusted ORs and 95% confidence intervals (CIs). Results: A total of 75 cases and 149 controls were included in the study. PCA identified six dietary groups, labeled as cereals and grains, vegetables, proteins, dairy products, fruits, and sugars. Bivariate analysis showed that consumption of vegetables, fruits, sugars, and total energy intake were associated with change in PC risk. In multivariable-adjusted models comparing highest versus lowest levels of intake, we observed significant lower odds of PC in association with vegetable intake (OR 0.24; 95% CI, 0.07-0.85, P=0.012) and a higher likelihood with the total energy intake (OR 9.88; 95% CI, 2.56-38.09, P<0.0001). There was also a suggested link between high fruit consumption and reduced odds of PC. Conclusions: The study supports the association between dietary factors and the odds of PC development in Egypt. It was found that higher energy intake is associated with an increase in likelihood of PC, while increased vegetable consumption is associated with a lower odds ratio.

摘要

背景

胰腺癌(PC)是一种严重且进展迅速的恶性肿瘤。识别包括饮食因素在内的风险因素对于制定预防策略至关重要。本研究聚焦于饮食与胰腺癌之间的可能联系。方法:我们开展了一项病例对照研究,纳入了2014年6月至2015年12月在米尼亚癌症中心确诊的所有胰腺癌患者以及来自普通人群的对照。通过个人访谈直接收集饮食数据。进行主成分分析(PCA)以确定饮食组。使用粗比值比(OR)以及调整后的OR和95%置信区间(CI)的多变量逻辑回归分析数据。结果:该研究共纳入75例病例和149例对照。主成分分析确定了六个饮食组,分别标记为谷物、蔬菜、蛋白质、乳制品、水果和糖类。双变量分析表明,蔬菜、水果、糖类的摄入以及总能量摄入与胰腺癌风险变化相关。在比较最高摄入量与最低摄入量的多变量调整模型中,我们观察到蔬菜摄入与胰腺癌发生几率显著降低相关(OR 0.24;95% CI,0.07 - 0.85,P = 0.012),而总能量摄入则与更高的发生几率相关(OR 9.88;95% CI,2.56 - 38.09,P < 0.0001)。高水果摄入量与胰腺癌发生几率降低之间也存在潜在联系。结论:该研究支持埃及饮食因素与胰腺癌发生几率之间的关联。研究发现,较高的能量摄入与胰腺癌发生可能性增加相关,而蔬菜摄入量增加与较低的比值比相关。
