Along the course of occurrence and development of liver cancer,the corresponding somatic cells accumulate some important genetic *** variations may be divided into two *** the genetic changes closely related to etiology of liver cancer,the well-known cases include insertion and integration of the hepatitis B virus(HBV) DNA after infection,and mutations at site 249 of the tumor suppressor gene p53 induced by exposure to aflatoxin *** secondary genetic changes include amplification and deletion of certain chromosome regions,mutations in p53 at the sites other than 249,as well as the mutational activation of the Wnt/β-catenin signal *** tumor cells with these genetic variations may gradually become the dominant clones under evolutionary ***,identification of genetic susceptible against risk of liver malignancy is also an important aspect of research in this field.
