ARTICLE HIGHLIGHTS
Research background
Patients with MUTYH-associated polyposis (MAP) present an increased risk of extra-intestinal manifestations. Among them, a frequent extra-colonic manifestation is duodenal polyposis, which severity is traditionally classified with the Spigelman five-stage system (SS). The occurrence of SS IV duodenal polyposis is reported as the main risk factor for duodenal cancer. However, case reports of duodenal cancers in MAP suggest that they may develop in the absence of advanced benign SS disease, even without coexisting adenomas, and often involve the distal portion of the duodenum, out of the reach of conventional esophagogastroduodenoscopy.
Research motivation
Further studies are needed to define appropriate upper gastrointestinal surveillance programs in MAP patients.
Research objectives
To increase the knowledge regarding MAP and its associated duodenal polyposis, in light of recent literature evidence, we describe a series of MAP patients followed up at the Regina Elena National Cancer Institute of Rome, Italy. In addition, a literature revision on previously reported small bowel (SB) cancers in MAP was carried out.
Research methods
Clinical records of thirty-eight MAP patients followed up at the Regina Elena National Cancer Institute between 2003 and 2021 were considered. A literature revision by a PubMed search was carried out on previously reported SB cancers in MAP, without any limitations in terms of publication date and language.
Research results
In our case series, we identified two (6%) SB adenocarcinomas with no previous history of duodenal polyposis.
Research conclusions
Our observations suggest that the formula for staging duodenal polyposis and predicting risk factors for distal duodenum and jejunal cancer should be adjusted to take in consideration the presence of SS IV disease, rather than focusing only on this feature.
Research perspectives
A revision of upper gastrointestinal/SB surveillance guidelines may be required to better prevent SB cancer in MAP.
