• Importance A Cochrane review and network meta-analysis concluded that there is need for more research on adverse effects, including cancer, after treatment with tumor necrosis factor α (TNF-α) antagonists and that national registries and large databases would provide relevant sources of data to evaluate these effects.

  Objective To investigate whether patients with inflammatory bowel disease (IBD) exposed to TNF-α antagonists were at increased risk of developing cancer.
