胰腺癌的发病率逐年增加,40年来西欧增加2倍、美国增加3倍、日本增加4倍。胰腺癌对放疗、化疗均不敏感,唯一治愈的机会是根治性切除术。但手术切除率甚低,胰头癌的切除率仅10%～15%,胰体、尾部癌的切除率更低。因此,临床医师对大量无法切除的黄疸病例需要作出合理的姑息处理决策。胰腺癌的预后极差,以致Crile在1970年时即 The incidence of pancreatic cancer has been increasing year by year. Western Europe has doubled in 40 years, the United States has tripled, and Japan has quadrupled. Pancreatic cancer is not sensitive to radiotherapy or chemotherapy. The only cure is a radical resection. However, the resection rate is very low, the resection rate of pancreatic cancer is only 10% to 15%, and the resection rate of pancreatic body and tail cancer is even lower. Therefore, clinicians need to make reasonable palliative treatment decisions for a large number of cases of unresectable jaundice. The prognosis of pancreatic cancer is so poor that Crile was in 1970.
