The pancreatic head and neck constitute less than half (mean 46 +/- 5%) of the whole pancreas. There is no difference in the concentration of ductal epithelium between the head and the body of the pancreas. The preponderance of pancreatic exocrine tumours which arise in the head of the pancreas compared to the body is not, therefore, due to a larger number of cells at risk in the pancreatic head. This suggests that there is a greater risk of exocrine adenocarcinoma developing from the cells within the head of the pancreas than in those within the body of the pancreas.
胰头和胰颈占整个胰腺的比例不到一半(平均46±5%)。胰腺头部和体部的导管上皮浓度没有差异。因此,与胰体相比,发生在胰头的胰腺外分泌肿瘤占优势并非由于胰头中处于风险中的细胞数量更多。这表明,胰腺头部的细胞发生外分泌腺癌的风险比胰腺体部的细胞更高。
