Comments by Henry Lahore, founder of VitaminDWiki

  • This study shows that the people who got 10 micrograms of Vitamin D or Vitamin B12 had a 25% reduction in risk of getting Pancratic Cancer. The taking of the vitamins might have resulted in the decreased risk, but perhaps taking the vitamins was associated with some other health promotion behaviour which resulted in less pancratic cancer.
  • Suspect that taking both vitamins will result in even less pancratic cancer
  • Suspect that taking more of each vitamin would futher reduce the risk of pancreatic cancer

The relationship between vitamin intake and pancreatic cancer (PC) risk is disputed. We aimed to investigate the association between vitamin intake and the risk of PC via meta-analysis.

We conducted a meta-analysis of studies concerning vitamin intake and the risk of PC from EMBASE, MEDLINE, and Cochrane Library. The search yielded 25 correlative studies including 1,214,995 individuals. The relative risks (RR) were examined by a random-effect model or fixed-effect model. Subgroup analysis, dose-response analysis, sensitivity analysis, meta-regression, and publication bias analysis were used to analyze studies.

The RR of PC in the highest vitamin intake group was 0.90 (95% confidence interval, 0.83-0.98) compared with that in the lowest vitamin intake in the prospective studies. Different increments of vitamin intake and the risk of PC were examined with dose-response analysis, and a decrease in the risk of PC was observed with vitamin D (25%) and vitamin B12 (27%).

This meta-analysis found that vitamin intake can decrease the risk of PC, particularly vitamin D and vitamin B12.

From Discussion section of PDF

  • "This meta-analysis included more than 1.2 million human participants and 8000 PC cases. We found that vitamin consumption can moderately decrease the risk of PC. Daily consumption of 10mg/d of vitamin B12 or vitamin D can dramatically reduce the incidence of PC, 27% for vitamin B12 and 25% for vitamin D in the dose–response meta-analysis."
