Inconsistent results on the relationship between coffee consumption and pancreatic cancer risk has been reported in both epidemiological studies and previous meta-analyses. This updated meta-analyses was conducted to assess the association of coffee intake with pancreatic cancer risk. We evaluated the relationship of coffee ingestion and pancreatic cancer risk by performing a meta-analysis of prospective cohort studies and made an explicit document search in the PubMed database before November 2015. ⋯ Dose-response analysis indicated that every one-cup increase in coffee consumption was associated with an 1% increase in pancreatic cancer risk. No statistically significant publication biases existed. Coffee consumption may weakly increase the risk of pancreatic cancer.
