Objectives: There are conflicting results for the association between vitamin B6 intake with reduced pancreatic carcinoma risk. Thus, a meta-analysis was performed to summarize the evidences from epidemiological studies. Methods: We searched documents from PubMed-Medline, Web of Science, and Cochrane Library. The results were analyzed by using Stata software. Results: A total of nine studies were included. The multivariate-adjusted results found that the total RR values of pancreatic carcinoma was 0.65 (95% CI: 0.53–0.80) for the highest vitamin B6 intake vs the lowest vitamin B6 intake, and there was no significant heterogeneity among studies (I² = 42.0%, P = 0.087). Sensitivity analysis indicated that no single study leaded to an excessive change for the relation between vitamin B6 intake and pancreatic carcinoma risk. Conclusions: This meta-analysis suggested that vitamin B6 intake could significantly decrease pancreatic carcinoma risk. However, further study is needed based on the limitations of the current analysis.
