一、前言关于肝癌的病原学问题,目前尚未解决。在人类生活的环境中,致癌物质日益增多,有化学的、放射性的、病毒的等等。用分子水平来研究每一个人的基因种类有一定困难,所以对此问题尚需进行各方面的研究。本文就我科自1978年开展HBsAg的检测以来和1980年用地衣红染色所遇到的少数病例,结合复习手边有关资料、文献、对原发性肝癌的病原学进行 I. INTRODUCTION The etiology of liver cancer has not yet been resolved. In the environment of human life, there is an increasing number of carcinogenic substances, such as chemical, radioactive, and viruses. It is difficult to study the genetic types of each individual at the molecular level. Therefore, various aspects of this issue need to be studied. This article examines a few cases encountered in our department since the start of HBsAg testing in 1978 and in 1980 with lichen red staining, combining hands-on review of relevant data, literature, and etiology of primary liver cancer.
