本文对784例人类小肠癌的解剖分布进行了研究，并对现有的流行病学资料进行了分析，以确定这些罕见的肿瘤与其他胃肠道肿瘤和饮食的关系。小肠癌的解剖分布是不寻常的：大多数肿瘤发生在十二指肠或空肠近端，相对较少的肿瘤发生在中央肠道，只有在回肠下部才会出现预期数量的肿瘤。对现有流行病学数据的回顾表明，小肠癌与下消化道癌症之间存在相关性，但上消化道肿瘤之间没有相关性。小肠癌的发病率与蛋白质和脂肪的摄入量呈正相关。
The anatomic distribution of 784 human small bowel carcinomas was studied and available epidemiologic data were analyzed to determine the relation of these rare cancers to other gastrointestinal tumors and diet. The anatomic distribution of small bowel cancer is unusual: most tumors occur in the duodenum or proximal jejunum, relatively few tumors occur in the central bowel and only in the lower ileum do the expected number of tumors appear. Review of available epidemiologic data shows a correlation between small bowel cancer and lower, but not upper gastrointestinal cancer. The incidence of small bowel cancer is positively correlated with protein and fat consumption.
