Sixty-four cases of pancreatoduodenectomy were performed for ductal adenocarcinoma of the head of pancreas. According to the size of primary tumor, the cases were divided into 3 groups: less than 2 cm, 2.1 to 4.0 cm, and more than 4 cm. The corresponding one-year survival was 66.7%, 33.7%, and 25.0% (P less than 0.05), respectively. The one-year survival of cases with tumor confined to pancreas or only involving intrapancreatic common bile duct or duodenal wall in the ampullary region (100%) was higher than that of cases with microscopic and macroscopic local infiltration (33.3%, 54.5%) and that of cases with large or middle extrapancreatic vessels involved (11.1%) (P less than 0.001). The rate of lymph node metastases of all cases was 69%. The one-year survival of cases with primary lymph node metastases was lower than that of cases without it (32.4% v. 62.5%, P less than 0.05). Based on the above mentioned result, a new staging method is suggested.
对64例胰腺导管腺癌患者实施了胰十二指肠切除术。根据原发肿瘤大小，将病例分为3组：小于2厘米、2.1至4.0厘米和大于4厘米。相应的1年生存率分别为66.7%、33.7%和25.0%（P<0.05）。肿瘤局限于胰腺或仅累及壶腹区域胰内胆总管或十二指肠壁的病例（100%）的1年生存率高于有微观和宏观局部浸润的病例（33.3%、54.5%）以及有大或中等胰外血管受累的病例（11.1%）（P<0.001）。所有病例的淋巴结转移率为69%。有原发性淋巴结转移的病例的1年生存率低于无原发性淋巴结转移的病例（32.4%对62.5%，P<0.05）。基于上述结果，建议采用一种新的分期方法。
