胰腺癌占消化道肿瘤的8％～10％,一旦确诊,约有12％～15％的病例可行手术根治,术后五年生存率仅0～2％,90％以上患者多在确诊后一年左右死亡,平均生存期<6个月。因此,胰腺癌是一种恶性程度高,病程进展快,根治手术机会相对小,预后极差的消化系肿瘤。因此,胰腺癌的早期诊断及非手术治疗是当前临床治疗的重要手段之一。 一、选择性胰动脉造影 Pancreatic cancer accounts for 8% to 10% of digestive tract tumors. Once diagnosed, approximately 12% to 15% of cases are feasible for radical surgery. The 5-year survival rate after surgery is only 0-2%. More than 90% of patients are diagnosed one after the other. Years die, with an average survival of <6 months. Therefore, pancreatic cancer is a kind of digestive tumor with a high degree of malignancy, rapid disease progression, relatively small chance of radical surgery, and poor prognosis. Therefore, early diagnosis and non-surgical treatment of pancreatic cancer is one of the most important methods in clinical treatment. First, selective pancreatic arteriography
