胰腺癌的发病数每年达22,000例,且第一年死亡率达90％。目前认为靠模糊的症状和体征常会漏诊,血清癌胚抗原(CEA)的测定也无助于其早期诊断。1974年Banwo等叙述了胰瘤胚抗原(POA)测定法,发现50％的胰腺癌患者的血清POA水平升高,于肿瘤切除后下降,而复发时再度升高。在气管癌,偶在急性胰腺炎和晚期乳癌者中也见升高。关于血清核糖核酸酶的测定,现尚在核实其是否可用作胰腺癌诊断和治疗的依据。超声波,计算轴性断层摄影(Computerized axialtomography)和动脉造影可提供解剖上的研
The number of pancreatic cancers reaches 22,000 per year, and the first year mortality rate is 90%. It is currently believed that vague symptoms and signs are often missed, and the measurement of serum carcinoembryonic antigen (CEA) does not contribute to its early diagnosis. In 1974 Banwo et al. described the pancreatic embryonic antigen (POA) assay and found that serum POA levels increased in 50% of pancreatic cancer patients, decreased after tumor resection, and increased again at relapse. In tracheal cancer, it is also elevated in individuals with acute pancreatitis and advanced breast cancer. Regarding the determination of serum ribonuclease, it is still being verified whether it can be used as a basis for diagnosis and treatment of pancreatic cancer. Ultrasound, Computed Axial Tomography and Arteriography provide anatomical study
