Periampullary malignancy in Gardner's syndrome

Area of Science:

• Gastroenterology
• Oncology
• Genetics

Background:

• Familial polyposis coli (FPC) is an inherited condition characterized by numerous polyps in the colon.
• Periampullary malignancies are rare but serious complications that can arise in the vicinity of the ampulla of Vater.

Observation:

• The study reports three cases of FPC with associated periampullary malignancies.
• A literature review identified 16 additional cases, with five more unreported cases known.
• These findings suggest a link between FPC and these specific upper gastrointestinal tumors.

Findings:

• Periampullary malignancy is considered a distinct extracolonic manifestation of FPC.
• The condition should be viewed as a variant of Gardner's syndrome, which includes FPC and other non-colonic tumors.
• A significant association exists between FPC and the development of periampullary cancers.

Implications:

• Routine upper gastrointestinal surveillance is crucial for all patients diagnosed with FPC.
• Early detection of duodenal polyps in FPC patients is recommended.
• Surgical intervention for discovered duodenal polyps should be performed when surgically feasible to manage potential malignancy.
