近年来,胰腺癌呈现出“一高三低”的趋势,即发病率升高,早期诊断率低,根治手术率低,五年存活率低。要改善这种状况,关键是提高早期诊断率。由于人们想探索出筛选和早期诊断胰腺癌的有效手段,故近年来胰腺癌的实验室诊断研究发展较快。一、酶学诊断 In recent years, pancreatic cancer has shown a trend of “one high and three low”, ie, the incidence rate is increased, the early diagnosis rate is low, the rate of radical surgery is low, and the five-year survival rate is low. The key to improving this situation is to increase the rate of early diagnosis. Because people want to explore an effective means of screening and early diagnosis of pancreatic cancer, in recent years, laboratory diagnosis of pancreatic cancer has developed rapidly. First, enzymatic diagnosis
