由于图像诊断方法以及免疫生化检查方法的进展,使过去认为是很困难的肝、胆、胰腺癌的早期诊断已成为可能。严格说,这与早期胃癌的诊断等情况相比,尚不能称为早期诊断,仅能对有高危险性或有某些可视为先兆临床表现的患者,通过几种检查方法的组合,达到对于小癌的诊断。肝癌目前正致力于研究小肝癌的诊断问题。高危险性患者,即容易发生肝细胞癌的患者有以下几种情况。(1) HBsAg阳性的肝硬化患者(经长期观察约40%可发生肝癌)。(2) HBsAg阴性的肝硬化患者,过去有过手术或输血史者多系非甲非乙肝炎病毒所致之肝硬化,虽然肝癌的发生率较前者为低,但HBe抗体阳性者容易
Due to advances in image diagnosis methods and immunological biochemical examination methods, early diagnosis of liver, gallbladder, and pancreatic cancer that has been considered difficult has been made possible. Strictly speaking, compared with the diagnosis of early gastric cancer, it cannot be called an early diagnosis, and can only be achieved by a combination of several examination methods for patients who are at high risk or have certain clinical manifestations as aura. For the diagnosis of small cancers. Liver cancer is currently working on the diagnosis of small liver cancer. High-risk patients, who are prone to hepatocellular carcinoma, have the following conditions. (1) HBsAg-positive patients with cirrhosis (a long-term observation of about 40% of liver cancer). (2) In HBsAg-negative cirrhosis patients, cirrhosis caused by non-non-hepatitis B virus is mostly caused by surgery or blood transfusion history. Although the incidence of liver cancer is lower than that of the former, it is easy for patients with positive HBe antibody.
