摘　　要：BACKGROUND The presence of Spigelman stage(SS)IV duodenal polyposis is considered the most significant risk factor for duodenal cancer in patients with MUTYH-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.Core Tip:Case reports of duodenal cancers in MUTYH-associated polyposis suggest that they may develop in the absence of advanced Spigelman stage(SS)benign disease and often involve the distal portion of the duodenum.In our case series,we identified two(6%)small-bowel 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 should be adjusted to take into consideration the presence of SS IV disease,rather than focusing only on this feature.suggestive of invasive adenocarcinoma.
