• W69729465 abstract "The aim of the study was to assess the incidence of both types of liver cell dysplasia and concomitance with cirrhosis, hepatocellular carcinoma (HCC) and positive reaction for HBsAg in the autopsy material and an attempt to determine a relationship between these two types of liver cell dysplasia and hepatocellular carcinoma. Autopsy material included 102 cases of hepatocellular carcinoma, 101 cases of hepatocirrhosis without accompanying cancer and 106 control cases. Histological specimens stained with HE were analyzed for the presence of large liver cell dysplasia (LLCD) according to Anthony et al., small liver cell dysplasia (SLCD) according to Watanabe et al., the presence of macroregenerative nodules (< 8 mm) and antigen HBs (stained with orcein according to Shikata). The detected LLCD were also assessed semiquantitatively taking into account the number of dysplastic areas in a given case. Statistical significance of the results was tested with the chi square test. LLCD was most frequently detected in HCC with concomitant cirrhosis (55.3%), then in cirrhosis without HCC (40.6%), and in HCC without cirrhosis only in 12.5%. LLCD was found significantly more frequently (p < 0.05) in cirrhosis with HCC than in cirrhosis without HCC. Antigen HBs was found in 25.6% of cirrhoses and/or HCC. No significant differences in the presence of HBsAg were seen between the analyzed groups. The incidence of LLCD and HBsAg in controls was significantly lower than in other groups. A mean age at death in case of cirrhosis with HCC subdivided into that with or without LLCD was not significantly different, whereas in case with cirrhosis with LLCD age at death was 10.8 years higher (the difference statistically significant). Analysis of material with respect to gender revealed a high proportion of men in case of HCC with concomitant cirrhosis but without LLCD (13:1). A strong relationship was seen between the presence of positive reaction for HBsAg and LLCD (p < 0.001). Also the intensity of LLCD positively correlated with the presence of HBsAg. Furthermore, a positive correlation was seen between the presence of LLCD and macronodular cirrhosis (posthepatitic). The present findings suggest a closer relation between HBV infection and LLCD than between cirrhosis or HCC and LLCD. Also morphological patterns of LLCD foci do not confirm the hypothesis of some investigators about the precancerous character of these lesions. In the whole current material only seven cases of SLCD were detected. They were all present in cirrhotic livers with concomitant HCC. Both the morphological pattern of these lesions and their sometimes discerned close spatial relation with HCC foci indicate that SLCD is an alternative way of HCC development." @default.
