How common are pancreatic neuroendocrine tumors?
Pancreatic neuroendocrine tumors are rare, with an incidence of 0.43 per 100,000 population per year.
The incidence in the United States has increased in frequency over the past 30 years because of growing awareness, improvements in diagnostic imaging, and overall increased use of computed tomography (CT) and magnetic resonance imaging (MRI).
Autopsy series find a prevalence of 0.8% to 10%. PNETS account for only 1% to 3% of all pancreatic tumors and 7% of all NETs; only gastrointestinal (GI) carcinoids are more common.
