胰腺癌可发生于胰腺的任何部位,但多见于胰头,约占3/4,胰腺的体尾部约占1/4。从病理学分为2型,一种来自腺泡上皮,由圆形或多角形的小细胞组成;另一种来自胰腺导管,由柱状的肿瘤细胞组成。从大体观,胰腺癌为实质性,质硬,切面呈灰白色,边界不清。由于癌细胞浸润,此间含有极多的纤维组织,因此,癌瘤与周围组织的界限不清。选取临床2010年1月～2011年12月收治的30例胰腺癌患者超声检查报告如下。
Pancreatic cancer can occur in any part of the pancreas, but more common in the head of the pancreas, accounting for about 3/4, about 1/4 of the body of the pancreas. From the pathology is divided into 2 types, one from the acinar epithelium, composed of small round or polygonal cells; the other from the pancreatic duct, composed of columnar tumor cells. From a general perspective, pancreatic cancer is substantive, hard, pale gray, the border is unclear. Due to the infiltration of cancer cells, which contains a lot of fibrous tissue, therefore, cancer and the surrounding tissue unclear. Thirty patients with pancreatic cancer admitted to our hospital from January 2010 to December 2011 were enrolled in this study.
