胰导管腺癌是西方世界最常见的致死性癌.近年来世界报道其可切除率为10%～20%,个别单位的术后死亡率低于10%,5年存活率达24%.在根治切除后疾病的发展需要接受辅助治疗;多数病人在切除床发生局部复发.尽管手术切除病人中扩大根治术的比例增加,局部发生率仍无改变.继发转移最常发生在肝脏(23%～52%),腹腔(27%～62%)和腹外部位(8%～29%),孤立的局部复发不超过20%.
Pancreatic ductal adenocarcinoma is the most common fatal cancer in the western world. In recent years, the world has reported a resectable rate of 10% to 20%. The mortality rate of individual units is less than 10%, and the 5-year survival rate is 24%. The development of the disease after radical excision requires adjuvant therapy; most patients experience local recurrence in the excision bed. Although the proportion of patients undergoing radical mastectomy in surgical resection increases, the local incidence remains unchanged. Secondary metastasis occurs most often in the liver (23% ~ 52%), abdominal cavity (27% ~ 62%) and abdominal external position (8% ~ 29%), local recurrence of no more than 20%.
