This study aimed to clarify the clinical significance or pathogenesis of CDT1 expression in both non-cancerous and cancerous liver in HCC cases, including previously published data. We investigated the association between the expression of CDT1 in non-cancerous or cancerous liver tissues and histologic findings or biochemical examination results in 62 cases. We also examined the dual localization between CDT1 and FbxW7, P57kip2, P53 and c-Myc by confocal laser scanning microscopy. CDT1 mRNA expression was significantly higher in cancerous liver than in noncancerous liver (p\u003C0.0001) . Elevated CDT1 mRNA expression indicates a significantly degree of inflammatory cell infiltration within lobules, along with elevated serum transaminase levels, and hepatic spare decline. CDT1 mRNA was highly expressed in a group of poorly differentiated cancer cells. CDT1 co-localized with P57kip2, Fbwx7, P53 and c-Myc in the nucleus or cytoplasm of hepatocytes and cancer cells. We found that CDT1 mRNA expression could represent the degree of hepatic spare ability and the high carcinogenic state.  \nKey Words: chromatin licensing and DNA replication factor 1, hepatocellular carcinoma, proliferation of atypical hepatocytes, Ki-67, P57 kip2  \nThe pathogenesis of HCC development remains unclear. On  \nthe other hand, we also reported that the degree of irregular regeneration (IR) of hepatocytes were important risk factor for the development of hepatocellular carcinoma (HCC) from chronic hepatitis C (CHC) or liver cirrhosis (LC) .(1,2) Further‐ more, we have reported the extent of proliferation of atypical hepatocytes (POAH), which is one of the irregular regeneration (IR) of hepatocytes populations as a strong risk factor for the development of HCC from CHC or LC.(3) In addition, we recently examined the pathological findings of non-cancerous liver sections in 356 cases with HCC and reported that the extent of POAH was a significant factor involved in the postoperative recurrence of HCC.(4)  \nIn addition, we examined the pathological findings of noncancerous liver sections in 356 cases with HCC and reported that the extent of POAH was a significant factor involved in the post‐ operative recurrence of HCC.(4) It has been reported association with chromatin licensing and DNA replication factor 1 (CDT1) expression and pathogenesis of cancer development in many  \ncancers.(5–9) Yu et al.(8) and Karavias et al.(9) reported that higher CDT1 expression was significantly associated with reduced overall survival, which supported our results in the previous study.
