Distinction may not be possible in advanced cases. There is a high incidence of these tumors in patients with FAP. AC can be broadly classified as primary, metastatic, or systemic. Primary cancers arise in the pancreas or other periampullary sites and can demonstrate either endocrine or non-endocrine differentiation. Ductal adenocarcinoma is by far the most common periampullary malignant tumor.
The incidence of AC was reported as 0.7 cases per 10,000 males and 0.4 cases for females between 1985 and 2005. AC represents 0.5% of all gastrointestinal malignancies.
