Abstract
The expression of the inositol 1,4,5-trisphosphate receptor type 3 (ITRP3) in hepatocytes is a common event in the pathogenesis of hepatocellular carcinoma (HCC), regardless of the type of underlying liver disease. However, it is not known whether ITPR3 expression in hepatocytes is involved in tumor maintenance. The aim of the present study was to determine whether there is an association between ITPR3 expression and clinical and morphological parameters using HCC samples obtained from liver explants from patients (n=53) with different etiologies of underlying chronic liver disease (CLD). ITPR3 expression, mitosis and apoptosis were analyzed in human liver samples by immunohistochemistry. Clinical and event-free survival data were combined to assess the relationship between ITPR3 and liver cancer growth in patients. RNA sequencing analysis was performed to identify apoptotic genes altered by ITPR3 expression in a liver tumor cell line. ITPR3 was highly expressed in HCC tumor cells relative to adjacent CLD tissue and healthy livers. There was an inverse correlation between ITPR3 expression and mitotic and apoptotic indices in HCC, suggesting that ITPR3 contributed to the maintenance of HCC by promoting resistance to apoptosis. This was confirmed by the upregulation of CTSB, CHOP and GADD45, genes involved in the apoptotic pathway in HCC. The expression of ITPR3 in the liver may be a promising prognostic marker of HCC.

Prediction of early hepatocellular carcinoma recurrence using germinal center kinase-like kinase. Oncotarget 2018; 7:49765-49776.

Abstract
Germinal center kinase-like kinase (GLK) is a key controller of autoimmunity. In this study, we assessed the clinical relevance and tumorigenic effects of GLK in hepatocellular carcinoma (HCC). Using immunohistochemistry, we showed that the GLK proportion score increased in both cancerous and adjacent non-cancerous liver tissue from patients with HCC recurrence. A Kaplan-Meier analysis revealed that patients with a wide distribution of GLK in non-cancerous liver tissue had a higher rate of HCC recurrence than those with very low or no GLK expression. Multivariate Cox regression analyses indicated that a high GLK proportion score in non-cancerous liver tissue was an independent predictor of early HCC recurrence after resection. Lentiviral vector-mediated overexpression of GLK activated the nuclear factor kappa B (NFκB) signaling cascade and accelerated cell cycle progression in primary human hepatocytes, thereby promoting proliferation. An increase in GLK expression coincided with NFκB activation and enhanced expression of proliferating cell nuclear antigen in HCC tissue. Our findings demonstrate a potential hepatocarcinogenic effect of GLK and the feasibility of using GLK to predict early HCC recurrence.

Abstract
BACKGROUND Predictors of poor prognosis of solitary hepatocellular carcinoma (SHCC), a subgroup encompassing most patients with the malignancy, are still controversial. Hence, risk factors for portal vein tumor thrombosis (PVTT) in SHCC are obscure. The present study was designed to address this issue. METHOD Clinicopathological and follow-up data for 156 consecutive patients with SHCC following curative hepatic resection were analyzed using uni- and multi-variate analyses. RESULTS Univariate analysis showed that PVTT, tumor-node-metastasis (TNM) stage, Edmondson-Steiner grade and preoperative serum alpha-fetoprotein (AFP) level were associated with the overall and disease-free survival, whereas tumor size only influenced the overall survival. In multivariate Cox regression tests, Edmondson-Steiner grade and TNM stage were independent prognostic markers for both overall and disease-free survival. In addition, the Chi-square test showed that AFP level and Edmondson-Steiner grade were correlated with PVTT. Among them, only Edmondson-Steiner grade was shown to be of independent significance for PVTT in multi-variate logistic regression analysis. Additionally, AFP, the sole preoperative factor for PVTT, was not adequately sensitive and specific. CONCLUSIONS Factors relating to post-surgical prognosis and PVTT in SHCC are all tumor-related. Of these, Edmondson-Steiner grade and TNM stage might be of particular importance in survival analysis. In addition, accurate prediction of PVTT by clinicopathological parameters before surgery remains difficult.

Abstract
BACKGROUND The 6th edition TNM staging (TNM-6) for hepatocellular carcinoma (HCC) has been recommended. However, its superiority, in contrast to the previous 5th edition (TNM-5), has not been fully recognized. Besides, tumor differentiation was not included. The current study was designed to compare the value of these two staging systems and, more importantly, to elucidate whether Edmondson-Steiner grading, a well-acknowledged histological classification, is helpful in further discriminating different prognosis of HCC. METHODS Prospectively collected clinicopathological and follow-up data of consecutive 171 patients with HCC undergoing curative hepatic resection (CHR) were reviewed retrospectively. The impacts of variables on survival were determined by univariate and multivariate statistical analyses. RESULTS The differences of survival between stages of the TNM-6 and TNM-5 were almost significant, except for disease-free survival for TNM-5. Moreover, TNM-6 might be a more powerful prognostic predictor compared with TNM-5, although their impacts on survival were all not independent, unlike Edmondson-Steiner grading. For patients with each stage of TNM-6, Edmondson-Steiner grade was the sole significant variable in both univariate and multivariate analyses. Finally, a novel scoring criteria (prognostic scoring for CHR, PSCHR) integrating Edmondson-Steiner grading and TNM-6 was attempted and statistically shown to be of independent significance and stronger predicting value for prognosis of curatively resected HCC. CONCLUSION TNM-6 revealed to be more significantly prognostic than TNM-5 in patients with HCC after curative hepatic resection. Edmondson-Steiner grading could raise the predictive efficiency of TNM-6 for postresectional survival of patients with HCC. Therefore, PSCHR containing Edmondson-Steiner grading was preliminarily proposed.

Abstract
BACKGROUND Surgical resection for large (> 10 cm) hepatocellular carcinoma (HCC) is believed by many to be ineffective. The objective of the current study was to review the outcome of partial hepatectomy in patients with large HCC. METHODS Between 1985 and 2002, 193 consecutive patients who underwent partial hepatectomy for HCC were identified from a prospective database. The 82 patients with tumors > 10 cm were compared with the remaining 111 patients with < or = 10 cm tumors. Clinicopathologic features were analyzed and prognostic factors were evaluated by univariate and multivariate analysis. RESULTS The 5-year overall survival for patients with large HCC was 33% with a median of 32 months. Patients with < or = 10 cm tumors had similar survival. Furthermore, there was no significant difference between the groups in operative mortality (2% in large HCC vs. 6%) or recurrence rate. In patients with large HCC, vascular invasion by tumor and intraoperative blood loss > 2 liters predicted overall survival on multivariate analysis. CONCLUSIONS Partial hepatectomy is safe for patients with large HCC. In selected patients with large tumors, resection achieves similar overall survival and recurrence-free survival to that of patients with smaller tumors. Minimizing intraoperative blood loss appears to be critical for favorable long-term outcome in patients with large HCC.

Abstract
To clarify the genetic aberrations involved in the development and progression of hepatitis C virus-associated hepatocellular carcinoma (HCV-HCC), we investigated DNA copy number aberrations (DCNAs) in 19 surgically resected HCCs by conventional CGH and array CGH. Conventional CGH revealed that increases of DNA copy number were frequent at 1q (79% of the cases), 8q (37%), 6p (32%), and 10p (32%) and that decreases were frequent at 17p (79%), 16q (58%), 4q (53%), 13q (42%), 10q (37%), 1p (32%), and 8p (32%). In general, genes that showed DCNAs by array CGH were usually located in chromosomal regions with DCNAs detected by conventional CGH analysis. Increases in copy numbers of the LAMC2, TGFB2, and AKT3 genes (located on 1q) and decreases in copy numbers of FGR/SRC2 and CYLD (located on 1p and 16q, respectively) were observed in more than 30% of tumors, including small, well-differentiated carcinomas. These findings suggest that these genes are associated with the development of HCV-HCC. Increases of MOS, MYC, EXT1, and PTK2 (located on 8q) were detected exclusively in moderately and poorly differentiated tumors, suggesting that these alterations contribute to tumor progression. In conclusion, chromosomal and array CGH technologies allow identification of genes involved in the development and progression of HCV-HCC.

Abstract
BACKGROUND AND OBJECTIVES Recurrence after partial liver resection for hepatocellular carcinoma (HCC) is a major cause of death from this disease. To identify risk factors for early death from recurrence after liver resection for HCC. METHODS All 547 patients in this study had greater than 1 year of follow-up after complete resection of HCC (1980-1999) at one of the four hepatobiliary centers in Japan, France, and the United States. Patients who died of recurrence < or =1 year post-resection and all of those alive at least 1 year were compared. Survival and clinicopathological factors associated with death from recurrence within 1 year of resection were analyzed. RESULTS Overall postoperative mortality rate was 5%. In the first postoperative year, 123 (22%) patients died. Of these, 53 (43%) died of recurrence, 30 (24%) of postoperative complications, and 40 (33%) of liver failure/hemorrhage. On multivariate analysis, tumor size greater than 5 cm (P < 0.02; odds ratio, 3.0), multiple tumors (P < 0.01; odds ratio, 3.3), and greater than 5 mitoses per 10 high-power fields (P < 0.03; odds ratio, 3) were associated with increased risk of early death due to recurrence. CONCLUSIONS These findings enable identification of patients with HCC who are at high risk for early death due to recurrence following potentially curative resection who might be candidates for adjuvant therapy trials.

Abstract
BACKGROUND Proliferating cell nuclear antigen (PCNA) is a nuclear protein involved in DNA-synthesis and repair. During DNA-synthesis and repair the only active PCNA fraction is tightly bound to DNA. Similarly, during DNA-repair, a fraction of p21 colocalizes with PCNA in a detergent-insoluble form. AIM The aim of the study was to analyze to what extent the presence of DNA-bound PCNA and p21 correlates with cell proliferation and DNA-repair in hepatocellular carcinoma (HCC). METHODS Twenty-six HCCs and surrounding cirrhosis were studied. The DNA-bound and detergent-soluble fractions of PCNA and p21 were analyzed by immunoblotting. P53 and Ki67-Labeling Index (Ki67-LI) were evaluated by immunocytochemistry. RESULTS Soluble fractions of PCNA and p21 were found in all samples. One out of 26 cirrhotic samples displayed a DNA-bound fraction of PCNA while no case expressed DNA-bound p21. Fourteen HCCs showed a DNA-bound PCNA fraction. A highly significant correlation was found between Ki67-LI and DNA-bound PCNA but not with detergent-soluble PCNA. DNA-bound p21 and PCNA, indicating ongoing DNA repair activity, were present in 6 of these 14 HCCs and correlated with a high histological grade and high Ki67-LI. CONCLUSIONS Our results suggest that in HCC PCNA participates both in DNA synthesis and repair and that highly proliferating HCCs may display a sustained DNA-repair.

Abstract
BACKGROUND Hepatoma-derived growth factor (HDGF) is a novel growth factor derived from a hepatoma cell line. The current study was designed to elucidate the role of HDGF expression during the pathogenesis of hepatocellular carcinoma (HCC). METHODS HDGF expression in hepatoma cell lines was analyzed using the reverse transcriptase-polymerase chain reaction (RT-PCR), Western blot analysis, and immunofluorescence analysis. Immunohistochemical studies were performed to examine the intensity and spatial distribution of HDGF immunostaining in 105 HCC specimens. To evaluate its prognostic value, the labeling index of HDGF immunostaining was analyzed for potential correlations with the clinicopathologic characteristics of HCC. RESULTS RT-PCR and Western blot analysis detected increased HDGF expression in malignant hepatoma cell lines. In resected HCC specimens, HDGF immunostaining was detected in the nuclei and cytoplasm of hepatocytes and hepatoma cells. HDGF levels in hepatoma tissue samples were significantly higher than in adjacent nontumor tissue samples (P < 0.05). Elevated nuclear HDGF levels were found to be correlated with loss of differentiation features (P < 0.05), absence of tumor capsules (P < 0.01), high alpha-fetoprotein levels (P < 0.05), and overexpression of proliferating cell nuclear antigen (P < 0.001). Kaplan-Meier analysis indicated that patients with higher nuclear HDGF levels had a shorter duration of survival and a higher incidence of recurrence (P < 0.001). Multivariate analysis indicated that for patients with HCC, the nuclear HDGF level is an independent prognostic factor for overall and disease-free survival. CONCLUSIONS Increased HDGF expression is correlated with the proliferating states of HCC and represents a novel prognostic factor for patients with HCC who have undergone surgery.

Abstract
BACKGROUND This study compares liver resection (LR) or transplantation (LTx) in an attempt to reevaluate the indications for treatment. STUDY DESIGN One hundred fifty-four LRs and 121 LTxs performed from 1985 to 1999 were considered. Survival and recurrence rate, together with age, gender, liver disease, Child-Pugh classification, alpha-fetoprotein (AFP), tumor capsule, vascular invasion, size, number of nodules, histologic grade, and pTNM were considered. Followup was completed in all cases (mean +/- SD = 3.2 +/- 2.9 years). RESULTS The 5- and 10-year actuarial survival rates were 61.7% and 59.8% in LTx and 46.9% and 28.0% in LR (p = 0.08). Recurrence-free survival was 85.9% and 85.9%, respectively, in LTx and 42.8% and 30.7% in LR (p < 0.0001). In both groups, size, capsule, AFP, vascular invasion, grade, pTNM, Child-Pugh classification, and age were all significantly related to survival and cancer recurrence. pTNM, AFP, Child-Pugh classification, and age, in LR, and capsule, AFP, and viral cirrhosis, in LTx, were significant independent variables in Cox's regression model for survival. Only AFP, vascular invasion, and grade were significant in both groups for recurrence. CONCLUSIONS LTx offers better recurrence freedom than LR, but longterm survival is not significantly different in the two series. A strict selection should be made to optimize graft allocation. Size and multifocality should not be considered absolute contraindications for LTx. AFP, vascular invasion, and grade are more likely to reflect the risk of recurrence of the disease. LR should be considered in patients who do not fulfill transplant criteria and also in some categories of patients with certain tumor characteristics (small resectable tumors in well-compensated cirrhosis).

Abstract
Liver transplantation (LTx) is the best treatment for hepatocellular carcinoma (HCC), but should be offered only to selected patients. The usual procedure is to transplant only for small and unilobular tumors. The aim of this paper is to verify whether the actual indication criteria are still justified. The details of 121 patients with HCC who were submitted to LTx from 1985 to 2000 were analyzed. Age, gender, liver disease, Child class, alpha-fetoprotein (AFP) level, presence of tumor capsule, vascular invasion, size and number of nodules, histological grade, and pTNM were considered. The 5- and 10-year actuarial survival rates were 61.7% and 53.1%. Freedom from recurrence was 85.9% and 85.9%, respectively. At univariate analysis, size, presence of capsule, AFP levels, vascular invasion, grade, pTNM, transarterial chemoembolization (TACE), Child class, and age were all significantly related to survival and/or cancer recurrence. Presence of capsule, AFP levels, and viral cirrhosis were independent variables in Cox's analysis for survival, whereas histological grade, AFP levels, and vascular invasion were significant independent variables for recurrence. In conclusion, a strict selection should be made to optimize graft allocation while size and multifocality should probably no longer be considered a contraindication for LTx. Histological grade, AFP levels, and vascular invasion, as indicator of tumor behavior, more likely reflect the risk of recurrence.

BACKGROUND Amplifications of 1q21, c-myc at 8q24.1, and AIB1 at 20q12 are genetic alterations that are detected frequently in hepatocellular carcinoma (HCC). The authors evaluated the association of these amplifications with the prognosis of patients with HCC. METHODS In the current study, amplification of 1q21, c-myc, and AIB1 was analyzed in 560 specimens from 400 patients with HCC and 20 patients with benign liver lesions using fluorescence in situ hybridization with high-throughput tissue microarray. Differences of amplification patterns were compared between small and large HCC, single nodular and multiple nodular HCC, primary and metastatic HCC, and primary and recurrent HCC. RESULTS Significant differences between single nodular and multiple nodular HCC were detected in c-myc amplification (12% vs. 38%; P < 0.01) and AIB1 amplification (16% vs. 30%; P < 0.05). More frequent c-myc amplification was detected in metastatic HCC (45%) compared with primary HCC (29%) and in recurrent HCC (60%) compared with primary HCC (38%). Similarly, more frequent AIB1 amplification was observed in metastatic HCC (41%) compared with primary HCC (23%) and in recurrent HCC (60%) compared with primary HCC (29%). However, no significant differences in 1q21 amplification were observed. CONCLUSIONS The current results strongly suggest that amplifications of the c-myc and AIB1 oncogenes are late genetic alterations in the progression of HCC and are correlated with a poor prognosis.

Abstract
The human c-erb B2 proto-oncogene (Her2/ ) encodes a 185-kD transmembrane putative growth factor receptor of the tyrosine kinase family. Overexpression or amplification of this oncoprotein/oncogene has been established in breast, ovarian, salivary gland, and gastric carcinomas and has been implicated in other neoplasms. Recently, overexpression of c-erb B2 has been demonstrated in hepatocellular carcinoma using enzyme-linked immunosorbent assay. Patients with hepatocellular carcinoma have a poor prognosis, and overexpression of c-erb B2 may have prognostic and treatment implications. The authors evaluated the expression and amplification of c-erb B2 in hepatic neoplasms utilizing routine immunohistochemistry and fluorescence in situ hybridization. Formalin-fixed paraffin-embedded tissue sections from 27 hepatocellular carcinomas and 7 hepatocellular adenomas were immunostained with anti-c-erb B2 utilizing a modified avidin-biotin technique following heat induced antigen retrieval. Ten sections from hepatocellular carcinomas were subjected to fluorescence in situ hybridization assay. Positive and negative controls stained appropriately. Slides were evaluated independently by two pathologists. None of the hepatocellular carcinomas or hepatocellular adenomas was immunoreactive with anti-c-erb B2. Adjacent cirrhotic liver parenchyma, present in 11 cases, was also uniformly negative. None of hepatocellular carcinomas showed any evidence of c-erb B2 amplification by fluorescence in situ hybridization. Immunoreactivity for c-erb B2 was not demonstrated in hepatocellular adenomas, cirrhotic livers, or hepatocellular carcinomas using routine immunohistochemical methods. C-erb B2 amplification was not demonstrated in hepatocellular carcinomas. Neither overexpression nor amplification of c-erb B2 (Her2/ ) can be regarded as a useful prognostic factor in hepatocellular carcinoma.

Abstract
BACKGROUND The cyclin-dependent kinases (CDKs) CDC2 and CDK2 are key regulators of the cell cycle. The expression of the CDK alone does not necessary reflect their true activities because they are highly regulated by post-translational mechanisms. Human hepatocellular carcinoma (HCC) is one of the most common cancers in the world, but the kinase activities of CDKs in HCC have not been examined. METHODS Here we examined the protein expression and kinase activities associated with CDC2 and CDK2 in HCC and the corresponding non-tumorous liver tissues. RESULTS CDC2 and CDK2 are activated in HCC in over 70% and 80% of the cases, respectively, but have little correlation with clinical parameters and PCNA expression. Interestingly, PCNA was readily detectable in extracts from non-tumorous liver, but more than 60% of samples contain higher concentration of PCNA in HCC than the corresponding non-tumorous tissues. CDC2 and CDK2 are generally activated in the same HCC samples, but the extent of their activation varied significantly, suggesting that the pathways leading to the activation of CDC2 and CDK2 can be regulated independently. Both positive regulators of CDK activity like cyclins and CDKs, and negative regulators of CDK activity like p21(CIP1/WAF1) and Thr14/Tyr15 phosphorylation were up-regulated in HCC. CONCLUSION CDC2 and CDK2 are activated in HCC, and this may be due to a complex interplay between the level of the cyclin, CDK, CDK inhibitors, and inhibitory phosphorylation.

Abstract
BACKGROUND AND OBJECTIVES The prognosis of patients with hepatocellular carcinoma (HCC) undergoing hepatectomy depends mostly on tumor recurrence. Portal vein invasion (Vp) and intrahepatic metastasis (IM) might strongly reflect the invasiveness of HCC, but the number of patients in the present series in whom either of these factors were detected was small. In this study, we defined Vp and IM as the extratumor spread, and we focused on the relationship between recurrence in patients after hepatectomy and the extratumor spread and the mitotic activities of cancer cells, in the hope that careful monitoring of recurrence might be possible by simply analyzing histology of the resected specimens. METHODS Univariate and multivariate analyses were used to determine the factors potentially related to recurrence in 50 patients who underwent hepatectomy for HCC. RESULTS The cumulative recurrence rate at 5 years was 81.0%. In univariate analysis, absence of the extratumor spread, mitotic index of four or less, and curative resection were significantly correlated with low incidence of recurrence. In multivariate analysis, the extratumor spread was the only significant variable influencing recurrence. The mitotic index in HCCs with the extratumor spread was significantly higher than the mitotic index in HCCs without the extratumor spread. CONCLUSIONS As a predictive factor for recurrence after resection of HCC, the extratumor spread that reflects the malignant potential of cancer cells was found to be more accurate than is any single invasiveness parameter such as Vp or IM.

Abstract
OBJECTIVE To evaluate the current knowledge on the risk factors for recurrence, efficacy of adjuvant therapy in preventing recurrence, and the optimal management of recurrence after resection of hepatocellular carcinoma (HCC). SUMMARY BACKGROUND DATA The long-term prognosis after resection of HCC remains unsatisfactory as a result of a high incidence of recurrence. Prevention and effective management of recurrence are the most important strategies to improve the long-term survival results. METHODS A review of relevant English articles was undertaken based on a Medline search from January 1980 to July 1999. RESULTS Pathologic factors indicative of tumor invasiveness such as venous invasion, presence of satellite nodules, large tumor size, and advanced pTNM stage, are the best-established risk factors for recurrence. Active hepatitis activity in the nontumorous liver and perioperative transfusion also appear to enhance recurrence. Recent molecular research has identified tumor biologic factors such as the proliferative and angiogenic activities of the tumor as new risk factors for recurrence. There is a lack of convincing evidence for the efficacy of neoadjuvant or adjuvant therapy in preventing recurrence. Retrospective studies suggested that postoperative hepatic arterial chemotherapy might improve disease-free survival, but results were conflicting. For the management of postoperative recurrence, studies have consistently indicated that surgical resection should be the treatment of choice for localized recurrence, be it in the liver remnant or extrahepatic organs. Transarterial chemoembolization and percutaneous ethanol injection are widely used to prolong survival in patients with unresectable intrahepatic recurrence, and combined therapy with these two modalities may offer additional benefit. CONCLUSIONS Knowledge of the risk factors for postoperative recurrence provides a basis for logical approaches to prevention. Minimal surgical manipulation of tumors to prevent tumor cell dissemination, avoidance of perioperative blood transfusion, and suppression of chronic hepatitis activity in the liver remnant are strategies that may be useful in preventing recurrence. The efficacy of postoperative adjuvant regional chemotherapy deserves further evaluation. New concepts on the influence of tumor biologic factors such as angiogenic activity on recurrence of HCC suggest a potential role of novel approaches such as antiangiogenesis for adjuvant therapy in the future. Currently, the most realistic approach in prolonging survival after resection of HCC is early detection and aggressive management of recurrence. Randomized trials are needed to define the roles of various treatment modalities for recurrence and the benefit of multimodality therapy.

Abstract
AIM: To reveal the inhibitory effects of Curcuma aromatica oil (CAO) on cell proliferation of hepatoma in mice.
METHODS: Two tumor inhibitory experiments of CAO on hepatoma in mice were conducted. The inhibitory effects of CAO on proliferation of hepatoma in mice were evaluated by DNA image cytometry and immunohistochemical staining of proliferating cell nuclear antigen (PCNA).
RESULTS: The tumor inhibitory rates of CAO were 52% and 51% in two experiments, respectively. Compared with those of the saline-treated control groups, both differences were statistically significant (P < 0.01). In the group of mice treated with CAO, the cellular nuclear DNA OD value (249 ± 70), are as (623 μm2± 228 μm2) and DNA (2.38 ± 0.67) index of hepatic carcinomas were significantly lower than those of the control group (430 ± 160, 1073 μm2± 101 μm2 and 4.48 ± 0.71). CAO also could increase diploidy cell rates (29.00% ± 9.34% vs 2.97% ± 5.69%, P < 0.01) and decrease pentaploidy cell exceeding rate (30.04% ± 15.10% vs 70.89% ± 14.94%, P < 0.01). In the group of mice treated with CAO, the labeling indexes of proliferating cell nuclear antigen (PCNA-LI) were 30% ± 4%, which were significantly lower than 40% ± 6% of the control group (P < 0.01).
CONCLUSION: The inhibition of CAO on the growth of hepatoma in mice might be associated with its depression on cellular proliferative activity.

Abstract
The prognosis of patients with resectable hepatocellular carcinoma depends mainly on the anatomical extent of the tumour and on the general condition of the patient. Given the growing evidence that proliferation indices may be of prognostic significance in hepatocellular carcinomas and that parameters of cell loss (usually, but not exclusively, due to programmed cell death) are biologically relevant, the identification and quantitation of proliferative capacity and apoptosis may be of prognostic importance. In this study four different methods have been used to assess proliferation in a series of 193 curatively (R0) resected hepatocellular carcinomas: mitotic count, immunohistochemical assessment of MIB-1 (Ki-67), proliferating cell nuclear antigen (PCNA), and silver-stained nucleolar organizer regions (AgNORs). Apoptosis was assessed using the in situ-end labelling (ISEL) technique in combination with morphological criteria. Patients who received liver transplantation were excluded. The results obtained were compared with histopathological stage (according to UICC), Edmondson grade, several other histopathological factors, and survival rate. Significant statistical correlations were seen between the mitotic index, the rate of nuclear positivity for MIB-1 and PCNA, and the number of AgNOR dots. In univariate survival analysis, tumour stage and Edmondson grade, mitotic index, MIB-1 and PCNA index, and mean AgNOR number were significant factors influencing patients' survival. On multivariate Cox survival analysis, mitotix index, concomitant cirrhosis, Edmondson grade, and patient age were the only significant independent prognostic factors. Apoptosis was not related to prognosis or to other parameters examined. These results indicated that mitotic index is an additional prognostic parameter which could provide auxiliary information for patients' outcome. MIB-1 and PCNA immunostaining and AgNORs showed a good correlation among themselves. Apoptosis did not predict prognosis in hepatocellular carcinoma.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) over 10 cm in diameter at the time of diagnosis continues to account for a number of patients undergoing hepatic resection. This study evaluated the clinicopathological features and outcome following surgery for large HCC. METHODS Forty patients with a large HCC (greater than 10 cm) (group 1) resected between 1991 and 1996 were studied retrospectively. They were compared with 245 patients who had smaller HCCs (10 cm or less) (group 2). RESULTS No patient in group 1 had hepatitis C infection compared with 22.9 per cent in group 2 (P=0.001). Patients in group 1 were significantly younger, had higher alpha-fetoprotein levels (16750 versus 1864 ng/ml; P < 0.001), better liver function, a higher incidence of multiple tumours (27 of 40 versus 42.0 per cent; P=0.003) and venous invasion (35 of 40 versus 52.2 per cent; P < 0.001), and underwent more major resections (37 of 40 versus 26.5 per cent; P < 0.001) than those in group 2. Morbidity and mortality rates and hospital stay were comparable in the two groups. For group 1, the 1-, 3- and 5-year disease-free survival rates were 42, 30 and 28 per cent respectively. Multiple tumours, venous invasion and impaired liver function were factors associated with recurrence. CONCLUSION Large HCC had specific clinicopathological features. In selected patients, resection is safe and offers the chance of long-term disease-free survival.

Abstract
Prognostic factors in hepatocellular carcinoma (HCC) conventionally consist of staging with the tumour node metastasis system and grading by tumour cellular differentiation. There are also other factors useful in prognostication but most of them are clinical. With new discoveries in the pathobiology of cancers and introduction of new medical technology, pathological and biological factors of HCC in relation to prognosis have been studied quite extensively. Morphological features of the tumour, both gross and histological, have been found to be significantly related to tumour recurrence and patient survival. Recently, applications of new antibodies and techniques have enabled studies on cellular proliferation using different antibodies such as those for proliferating cell nuclear antigen and Ki-67 protein. These studies on cellular proliferation, as well as assessment of argyrophilic nucleolar organizing regions, have been shown to provide good prognostic significance. Flow cytometric studies on DNA ploidy and studies on expression of genes including the p53 gene, hormone receptors and others show less unanimous results in their prognostic significance. The influence of gender on survival is also reviewed. In conclusion, pathological and biological factors are useful and help to guide clinicians in the management of patients and in assessment of long-term prognosis.

Abstract
AIMS To assess cell proliferation and the presence of numerical chromosome aberrations involving chromosomes 1 and 8 in benign and malignant liver tumours. METHODS Cell proliferation was studied immunohistochemically in paraffin wax embedded material from 62 primary liver tumours (20 hepatocellular carcinomas, 16 cholangiocellular carcinomas, 15 liver cell adenomas, 11 focal nodular hyperplasias), and the results were compared with histological characteristics and clinical data. Copy numbers of chromosomes 1 and 8 were assessed by interphase fluorescence in situ hybridisation (FISH) with satellite probes in fresh tumour material. RESULTS The expression of proliferation associated antigen Ki67, using the monoclonal antibody MIB-1, and proliferating cell nuclear antigen (PCNA), using the antibody PC10, was found to be significantly higher in malignant versus benign liver tumours. Neither Ki67 nor PCNA expression were independent prognostic parameters. However, there was a tendency for a worse outcome (survival < 12 months) for patients with a high MIB-1 labelling index (> 20%) compared with patients having the same tumour stage and a low MIB-1 index. Aneusomy for chromosomes 1 and 8 was demonstrated by FISH in malignant tumours (six of seven hepatocellular carcinomas, four of five cholangiocellular carcinomas) but not in benign tumours (none of nine) or non-neoplastic liver (none of nine). CONCLUSION Both the determination of the proliferating cell fraction and FISH analysis are useful for distinguishing hepatocellular carcinoma from liver cell adenoma or focal nodular hyperplasia; high fractions of proliferating cells are predictive of an early relapse.

Abstract
BACKGROUND/PURPOSE The MIB-1 monoclonal antibody has been raised against recombinant parts of the Ki-67 antigen, which is a cell cycle-related nuclear protein that is elevated in late G1 and S phases. The aim of the study was to analyze the expression pattern of MIB-1 in hepatoblastoma and to assess whether it provides any prognostic information in clinical practice. METHODS Sections from formalin-fixed paraffin embedded tissues were collected from 18 patients who had hepatoblastoma and stained with MIB-1 antibody according to streptavidinbiotin method. A percentage score of positively stained nuclei, MIB-1 Labeling Index (LI), was determined and correlated with clinical variables. MIB-1 LI ranged from 0% to 39.5% with a mean value of 13.5%. Among them in 14 patients, who received preoperative chemotherapy, the authors analyzed the result of MIB-1 staining. RESULTS Although there were no significant correlations between MIB-1 LI and age, sex, or histological type, a statistically significant correlation was found between clinical stage and MIB-1 LI. Mean MIB-1 LI was lower in patients with stage I and II than in those with stages III and IV (P < .05). Metastatic lesions showed higher MIB-1 LI than primary lesions, indicating that metastatic tumor cells have an increased rate of cellular proliferation. Kaplan Meier survival curve showed that patients with MIB-1 higher than 10% (n = 3) had a worse survival rate than those with lower than 10% MIB-1 LI (n = 11), whereas there was no significant difference because of the limited number of cases. Because high MIB-1 LI was correlated with clinical stage and poor survival rate, MIB-1 LI may be considered an important prognostic factor in hepatoblastoma. CONCLUSION Although further studies, including larger series of patients, are required, the authors consider MIB-1 immunostaining an easy method to assess proliferative activity that provides useful prognostic information in hepatoblastoma.

Abstract
This review summarizes the efficacy of the most common therapeutic option for hepatocellular carcinoma (HCC), partial hepatic resection, taking into account not only its antitumoural effect, but also its consequences on survival. Partial hepatic resection results in 5 year survival rates as high as 45% in more favourable subgroups having: small tumours, well-differentiated tumours, unifocal tumours, a lack of vascular invasions, an absence of cirrhosis, and the fibrolamellar variant. Resection has been limited primarily by low resectability rates and recurrent disease. However, surgical resection in the form of partial hepatectomy is the preferred treatment for HCC. The early detection of tumours by screening high-risk populations is crucial. During the 12 year period between 1983 and 1994, hepatic resections were carried out in 382 patients with HCC. One hundred and fifty-three (40%) had HCC smaller than 5 cm in diameter. There were 294 male and 88 female patients, with an average age of 52.3 years. Among them, 45% had liver cirrhosis and 73% were positive for hepatitis B surface antigen. Two hundred and eighteen (57%) were positive for hepatitis C virus circulating antibodies (since 1991). Operative mortality was 3.9%. The overall survival rates at 1, 3 and 5 years were 71, 52 and 46%, respectively. Sex, cirrhosis, Child's staging, surgical procedure, blood loss, pathological pattern, presence of capsule, surgical margin and DNA ploidy appeared to be factors not related to prognosis. However, alpha-fetoprotein level, size (whether less than or greater than 5 cm), and vascular invasion were factors which significantly affect survival.
