Abstract

INTRODUCTION: Proton pump inhibitor (PPI) use is associated with increased serum gastrin levels and bacterial overgrowth, resulting in more toxic bile salt formation. Concern has risen that these factors may increase the risk of developing colorectal neoplasia. AIM: To investigate the association between the use of PPIs and the risk of colorectal cancer. METHODS: A population-based case-control study was conducted within the Dutch Primary Care Information (IPCI) database over the period 1996-2005. Cases with colorectal cancer were matched with up to 20 controls on age, gender, calendar time, and duration of follow-up prior to diagnosis. Cumulative exposure to PPIs was assessed in the 5 yr prior to diagnosis with a 1-yr lag time analysis. We calculated adjusted odds ratios (OR) with 95% confidence intervals (95% CI) using multivariate, conditional logistic regression analysis. RESULTS: Within the source population of 457,024 persons, we identified 595 colorectal cancer cases. The odds of colorectal cancer were not increased among patients ever using PPIs compared with patients who never used PPIs (OR 0.85, 95% CI 0.63-1.16). Also, the use of PPIs for >365 days was not associated with a greater risk of colorectal cancer (OR 0.79, 95% CI 0.44-1.41) compared with nonusers. The odds of colorectal cancer in neither the right nor the left hemicolon were significantly increased in patients using PPIs. CONCLUSION: The present study indicates no association between PPI use and the risk of colorectal cancer. Larger numbers of long-term PPI users are needed to confirm the absence of a risk-increasing effect of long-term PPI exposure.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Many studies over the years have not found a direct correlation between PPI use in clinical practice and an increased risk of CRC.

    “Nevertheless, it is fundamental to highlight that many studies over the years have not found a direct correlation between PPI use in clinical practice and an increased risk of CRC[154-156].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
