众多的研究表明，肝脏不典型增生（ａｔｙｐｉｔｉａｌｈｙｐｅｒｐｌａｓｉａ，ＡＨ）可以发展成肝细胞肝癌（ｈｅｐａｔｏｃｅｌｌｕｌｅｒｃａｒｃｉｎｏｍａ，ＨＣＣ），因而认为不典型增生系癌前病变，大量分子生物学的研究也证实了两者的同源发病学说。但从不典型增生如?
Numerous studies have shown that liver atypical hyperplasia (AH) can develop into hepatocellular carcinoma (HCC). Therefore, atypical hyperplasia precancerous lesions are considered. A large number of molecular biological studies have also confirmed the homology between the two. Disease theory. But never typical hyperplasia?
