MUTYH- associated polyposis: Is it time to change upper gastrointestinal surveillance? A single-center case series and a literature overview

Le résumé fourni par la source

BACKGROUND: -associated polyposis (MAP). However, advanced SS disease is rarely reported in MAP patients, and no clear recommendations on small bowel (SB) surveillance have been proposed in this patient setting. AIM: To research more because that case reports of duodenal cancers in MAP suggest that they may develop in the absence of advanced benign SS disease and often involve the distal portion of the duodenum. METHODS: We describe a series of MAP patients followed up at the Regina Elena National Cancer Institute of Rome (Italy). A literature overview on previously reported SB cancers in MAP is also provided. RESULTS: We identified two (6%) SB adenocarcinomas with no previous history of duodenal polyposis. Our observations, supported by literature evidence, suggest that the formula for staging duodenal polyposis and predicting risk factors for distal duodenum and jejunal cancer may need to be adjusted to take this into account rather than focusing solely on the presence or absence of SS IV disease. CONCLUSION: Our study emphasizes the need for further studies to define appropriate upper gastrointestinal surveillance programs in MAP patients.
