背景维生素 D 在胰腺癌病因学中的潜在作用尚不清楚,最近的研究表明存在正相关和负相关。患者和方法我们使用国际胰腺癌病例对照联盟 (PanC4) 的九项病例对照研究的数据来检查胰腺癌风险与膳食维生素 D 摄入量之间的关联。使用多变量逻辑回归估计研究特定的优势比 (OR),然后使用随机效应模型汇总 OR。从四项研究的子集中,我们还计算了补充维生素 D 摄入量和总维生素 D 摄入量之间关联的汇总估计值。 结果胰腺癌的风险随着维生素 D 膳食摄入量的增加而增加[每 100 国际单位 (IU)/天:OR = 1.13,95% 置信区间 (CI) 1.07–1.19,P= 7.4 × 10-6,P-异质性 = 0.52; ≥230 与 <110 IU/天:OR = 1.31,95% CI 1.10–1.55,P= 2.4 × 10-3,P-异质性 = 0.81],在视黄醇/维生素 A 摄入量较低的人群中,这种关联可能更强。结论:膳食维生素 D 摄入量越高,患胰腺癌的风险越高。需要进行更多研究来确定我们的发现是否有因果基础。
BackgroundThe potential role of vitamin D in the aetiology of pancreatic cancer is unclear, with recent studies suggesting both positive and negative associations.Patients and methodsWe used data from nine case–control studies from the International Pancreatic Cancer Case–Control Consortium (PanC4) to examine associations between pancreatic cancer risk and dietary vitamin D intake. Study-specific odds ratios (ORs) were estimated using multivariable logistic regression, and ORs were then pooled using a random-effects model. From a subset of four studies, we also calculated pooled estimates of association for supplementary and total vitamin D intake.ResultsRisk of pancreatic cancer increased with dietary intake of vitamin D [per 100 international units (IU)/day: OR = 1.13, 95% confidence interval (CI) 1.07–1.19,P= 7.4 × 10-6,P-heterogeneity = 0.52; ≥230 versus <110 IU/day: OR = 1.31, 95% CI 1.10–1.55,P= 2.4 × 10-3,P-heterogeneity = 0.81], with the association possibly stronger in people with low retinol/vitamin A intake.ConclusionIncreased risk of pancreatic cancer was observed with higher levels of dietary vitamin D intake. Additional studies are required to determine whether or not our finding has a causal basis.
