World J Gastroenterol 2012; 18:340-8. [PMID: 22294840 PMCID: PMC3261529 DOI: 10.3748/wjg.v18.i4.340] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/01/2011] [Revised: 08/25/2011] [Accepted: 08/31/2011] [Indexed: 02/06/2023] Open
Abstract
AIM: To investigate whether α-fetoprotein (AFP) and vascular endothelial growth factor receptor (VEGFR)-1 correlate with early recurrence of hepatoma/hepatocellular carcinoma (HCC).
METHODS: From 2000 to 2005, 114 consecutive patients with HCC underwent primary curative hepatectomy. The mean age was 60.7 (8.7) years and 94 patients were male. The median follow-up period was 71.2 mo (range: 43-100 mo). Immediately prior to commencing laparotomy, 5 mL bone marrow was aspirated from the sternum and collected in citrate-coated test tubes. The initial 2 mL of bone marrow aspirate was discarded in each case. AFP mRNA and VEGFR-1 mRNA in the bone marrow and peripheral blood (BM- and PH-AFP mRNA and BM- and PH-VEGFR-1 mRNA, respectively) were measured by real-time quantitative reverse transcription polymerase chain reaction. As normal controls, VEGFR-1 mRNA in the bone marrow and peripheral blood was also measured in 11 living liver donors. These data were evaluated for any correlation with early recurrence, comparing clinical and pathological outcomes.
RESULTS: The cut-off value of the BM-AFP mRNA and PH-AFP mRNA level in patients with HCC was set at 1.92 × 10-7 and zero, respectively, based on data from the controls. A total of 34 (29.8%) and six (5.4%) patients were positive for BM-AFP mRNA and PH-AFP mRNA, respectively. The BM-VEGFR-1 mRNA levels in all HCC patients were higher than those in the normal controls, and this was the case also for PH-VEGFR-1mRNA. The 25-percentile values for the BM- and PH-VEGFR-1 mRNA in HCC patients were used as the cut-off values for assigning the patients into two groups based on these transcript levels. The High group for BM- VEGFR-1 mRNA contained 81 (71.1%) HCC cases and the Low group was assigned 33 (28.9%) patients. These numbers for PH-VEGFR-1mRNA were 78 (75.0%) and 26 (25.0%), respectively. HCC recurred in 80 patients; in the remnant liver in 48 cases, in the remnant liver and remote tissue in 20, and in the remote tissue alone in 12. BM-AFP mRNA-positive cases showed a significantly higher rate of early recurrence (within 1 year of surgical treatment) compared with BM-AFP mRNA-negative patients (P = 0.0091). Patients were classified into four groups according to the level/status of their BM-VEGFR-1 and BM-AFP mRNA as follows: group A (n = 23), BM-VEGFR-1/BM-AFP mRNA = low/negative; group B (n = 57) high/negative; group C (n = 10) low/positive; group D (n = 24), high/positive. This classification was found to correlate with a recurrence of this disease within 1 year (P = 0.0228). The disease-free survival curve of group A was significantly better than that of groups B, C or D (P = 0.0437, P = 0.0325, P = 0.0225). No other classification (i.e., PH-VEGF-R1/BM-AFP, BM-VEGF-R1/PH-AFP, and PH-VEGF-R1/PH-AFP mRNA) showed such a correlation.
CONCLUSION: The evaluation of BM-AFP and BM-VEGFR-1 mRNA in patients with HCC may be a valuable predictor of disease recurrence following curative resection.

World J Gastroenterol 2011; 17:4817-24. [PMID: 22147984 PMCID: PMC3229632 DOI: 10.3748/wjg.v17.i43.4817] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2011] [Revised: 06/16/2011] [Accepted: 06/23/2011] [Indexed: 02/06/2023] Open
Abstract
AIM: To investigate the clinicopathologic features of bile duct tumor thrombus (BDTT) occurrence after treatment of primary small hepatocellular carcinoma (sHCC).
METHODS: A total of 423 patients with primary sHCC admitted to our hospital underwent surgical resection or local ablation. During follow-up, only six patients were hospitalized due to obstructive jaundice, which occurred 5-76 mo after initial treatment. The clinicopathologic features of these six patients were reviewed.
RESULTS: Six patients underwent hepatic resection (n = 5) or radio-frequency ablation (n = 1) due to primary sHCC. Five cases had an R1 resection margin, and one case had an ablative margin less than 5.0 mm. No vascular infiltration, microsatellites or bile duct/canaliculus affection was noted in the initial resected specimens. During the follow-up, imaging studies revealed a macroscopic BDTT extending to the common bile duct in all six patients. Four patients had a concomitant intrahepatic recurrent tumor. Surgical re-resection of intrahepatic recurrent tumors and removal of BDTTs (n = 4), BDTT removal through choledochotomy (n = 1), and conservative treatment (n = 1) was performed. Microscopic portal vein invasion was noted in three of the four resected specimens. All six patients died, with a mean survival of 11 mo after BDTT removal or conservative treatment.
CONCLUSION: BDTT occurrence is a rare, special recurrent pattern of primary sHCC. Patients with BDTTs extending to the common bile duct usually have an unfavorable prognosis even following aggressive surgery. Insufficient resection or ablative margins against primary sHCC may be a risk factor for BDTT development.

Abstract
Background Clinicians often experience extrahepatic metastases associated with hepatocellular carcinoma (HCC), even if no evidence of intrahepatic recurrence after treatment is observed. We investigated the pretreatment predictors of extrahepatic metastases in HCC patients. Methods Patients diagnosed with HCC without evidence of extrahepatic metastases were prospectively enrolled. We evaluated the correlation between extrahepatic metastases and pretreatment clinical variables, including serum tumor markers. Results A total of 354 patients were included. Seventy-six patients (21%) had extrahepatic metastases during the observation period (median, 25.3 months; range, 0.6-51.3 months). Cox regression multivariate analysis showed that serum protein induced by vitamin K absence or antagonist-II (PIVKA-II) production levels, the intrahepatic tumor stage, platelet count, and portal vein thrombosis were independent risk factors for extrahepatic metastases. Patients with a PIVKA-II production ≥ 300 mAU/mL had a 2.7-fold (95% confidence interval; 1.5-4.8; P < 0.001) and 3.7-fold (95% confidence interval; 2.0-6.6; P < 0.001) increased risk for extrahepatic metastases after adjustment for stage, platelet count, alpha-fetoprotein ≥ 400 ng/mL, and portal vein thrombosis according to the AJCC and BCLC staging systems, respectively. Conclusion PIVKA-II production levels might be a good candidate predictive marker for extrahepatic HCC metastases, especially in patients with smaller and/or fewer tumors in the liver with in stages regardless of serum alpha-fetoprotein.

KOREAN JOURNAL OF HEPATO-BILIARY-PANCREATIC SURGERY 2011; 15:83-9. [PMID: 26421022 PMCID: PMC4582554 DOI: 10.14701/kjhbps.2011.15.2.83] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/21/2011] [Accepted: 03/10/2011] [Indexed: 01/30/2023]
Abstract
PURPOSE Although surgical resection offers patients with HCC the chance of a cure, the post-resection tumor recurrence rate is high, with reported cumulative 5-year tumor recurrence rates ranging from 40 to 70%. The objective of this study was to investigate risk factors for intrahepatic recurrence after resection of hepatocellular carcinoma, especially in patients with hepatitis B virus infection. METHODS Between January 1999 and December 2003, 59 patients in our Hospital with hepatitis B virus infection underwent liver resection for hepatocellular carcinoma. Clinical, biological, and histopathological characteristics of these patients were collected and tested for their prognostic significance using a Chi-square test and a Student's t-test. Time to recurrence and survival rate were analyzed by the Kaplan-Meier method. RESULTS Of the 59 patients who underwent liver resection, 24 (41%) experienced intrahepatic recurrence. The 1-, 3-, and 5-year overall survival rates of total enrolled patients were 83%, 63%, and 42%, respectively. The 1-, 3-, and 5-year overall survival rates after recurrence were 87%, 52%, and 20%, respectively. The risk factors for early recurrence were elevated serum aspartate aminotransferase (AST) level (p=0.044) and larger tumor size (p=0.049). For late recurrence, greater tumor size (p=0.039) was the only risk factor. CONCLUSION Tumor size and serum aspartate aminotransferase are risk factors of intrahepatic recurrence after resection of HCC in patients with chronic hepatitis B virus infection. This finding indicates that patients who have these risk factors should be under more careful supervision and have more aggressive follow-up.

Abstract
AIM To reveal the manner of hepatocellular carcinoma (HCC) development in patients with nonalcoholic steatohepatitis (NASH) focusing on multicentric occurrence (MO) of HCC. METHODS We compared clinicopathological characteristics between patients with and without MO of HCC arising from NASH background. The clinical features were implicated with reference to the literature available. RESULTS MO of HCC was identified with histological proof in 4 out of 12 patients with NASH-related HCC (2 males and 2 females). One patient had synchronous MO; an advanced HCC, two well-differentiated HCCs and a dysplastic nodule, followed by the development of metachronous MO of HCC. The other three patients had multiple advanced HCCs accompanied by a well-differentiated HCC or a dysplastic nodule. Of these three patients, one had synchronous MO, one had metachronous MO and the other had both synchronous and metachronous MO. There were no obvious differences between the patients with or without MO in terms of liver function tests, tumor markers and anatomical extent of HCC. On the other hand, all four patients with MO of HCC were older than 70 years old and had the comorbidities of obesity, type 2 diabetes mellitus (T2DM), hypertension and cirrhosis. Although these conditions were not limited to MO of HCC, all the conditions were met in only one of eight patients without MO of HCC. Thus, concurrence of these conditions may be a predisposing situation to synchronous MO of HCC. In particular, old age, T2DM and cirrhosis were suggested to be prerequisite for MO because these factors were depicted in common among two other cases with MO of HCC under NASH in the literature. CONCLUSION The putative predisposing factors and necessary preconditions for synchronous MO of HCC in NASH were suggested in this study. Further investigations are required to clarify the accurate prevalence and predictors of MO to establish better strategies for treatment and prevention leading to the prognostic improvement in NASH.

Abstract
Background Multiple carcinogenesis is one of the major characteristics of human hepatocellular carcinoma (HCC). The history of multiple tumors, that is, whether they derive from a common precancerous or cancerous ancestor or individually from hepatocytes, is a major clinical issue. Multiple HCC is clinically classified as either intratumor metastasis (IM) or multicentric carcinogenesis (MC). Molecular markers that differentiate IM and MC are of interest to clinical practitioners because the clinical diagnoses of IM and MC often lead to different therapies. Methods We analyzed 30 multiple tumors from 15 patients for somatic mutations of cancer-related genes, chromosomal aberrations, and promoter methylation of tumor suppressor genes using techniques such as high-resolution melting, array-comparative genomic hybridization (CGH), and quantitative methylation-specific PCR. Results Somatic mutations were found in TP53 and CTNNB1 but not in CDKN2A or KRAS. Tumors from the same patient did not share the same mutations. Array-CGH analysis revealed variations in the number of chromosomal aberrations, and the detection of common aberrations in tumors from the same patient was found to depend on the total number of chromosomal aberrations. A promoter methylation analysis of genes revealed dense methylation in HCC but not in the adjacent non-tumor tissue. The correlation coefficients (r) of methylation patterns between tumors from the same patient were more similar than those between tumors from different patients. In total, 47% of tumor samples from the same patients had an r ≥ 0.8, whereas, in contrast, only 18% of tumor samples from different patients had an r ≥ 0.8 (p = 0.01). All IM cases were highly similar; that is, r ≥ 0.8 (p = 0.025). Conclusions The overall scarcity of common somatic mutations and chromosomal aberrations suggests that biological IM is likely to be rare. Tumors from the same patient had a methylation pattern that was more similar than those from different patients. As all clinical IM cases exhibited high similarity, the methylation pattern may be applicable to support the clinical diagnosis of IM and MC.

Abstract
PURPOSE This study investigates the usefulness of long-term interferon (IFN) therapy following radiofrequency ablation (RFA) for HCV-associated hepatocellular carcinoma (HCC). METHODS This is a retrospective observational study. Patients underwent pegylated IFN-α/ribavirin combination therapy for 48 weeks and then were maintained on IFN-α administration on average for 68 weeks (mean total duration 116 weeks). Patients who underwent IFN monotherapy were maintained on IFN administration on average for 78 weeks. RESULTS There were biases in the background factors between the IFN and non-IFN groups. Therefore, a covariate adjustment was performed using the propensity score. An analysis of 20-matched patients from each group showed the 5-year cumulative survival rate was higher in the IFN group than in the non-IFN group (100 and 76%, respectively), and the 3-year cumulative recurrence rate was significantly lower in the IFN group than in the non-IFN group (38.0 and 64.2%, respectively). In 14 patients (i.e., IFN responders), the serum alanine aminotransferase (ALT) level remained normalized at 30 IU/mL or lower, regardless of disappearance of serum HCV RNA. In these patients, the cumulative recurrence rate was low, the hazard ratio was 0.158 (95% confidence interval = 0.045-0.561, P = 0.004), and the serum albumin level was retained. CONCLUSION These results show the importance of maintaining the liver function and suggest that long-term IFN administration after RFA inhibits recurrence and contributes to an improved outcome in patients (in particular, IFN responders) who initially develop HCC.

Abstract
BACKGROUND Many previous studies have evaluated the histopathological features of tumours as risk factors for postoperative recurrence in hepatitis B virus (HBV)-associated hepatocellular carcinoma (HCC). However, there have been few large studies investigating the relationship between cyclooxygenase-2 (COX-2) expression in noncancerous regions of the liver and postoperative recurrence in the remnant liver, especially in HBV-related HCC. OBJECTIVE To evaluate the significance of COX-2 expression levels in noncancerous liver regions as a prognostic indicator of HCC in patients with HBV-related cirrhosis. METHODS A total of 124 patients who underwent curative resection for HCC were reviewed retrospectively. Immunohistochemistry was used to evaluate the expression of COX-2 in noncancerous liver tissue. Clinicopathological variables were compared between patients with high COX-2 expression (n=58 [COX-2-positive group]) and patients with low COX-2 expression (n=66; [COX-2-negative group]). Univariate and multivariate analyses were performed to identify factors that affected disease recurrence. RESULTS There was a significant correlation between COX-2 expression and alanine aminotransferase levels and vascular invasion. The recurrence-free survival rates in the COX-2-positive group were significantly lower than the rates in the COX-2-negative group. On multivariate analysis, the overexpression of COX-2 in noncancerous liver regions was found to be an unfavourable prognostic indicator for the recurrence of HCC. CONCLUSIONS The results of the current study suggest that overexpression of COX-2 in noncancerous liver regions is an independent and significant indicator predictive of early recurrence of HCC in patients with HBV-related cirrhosis.

Abstract
AIM Hepatic resections for hepatocellular carcinoma (HCC) in cirrhotic liver are characterized by early recurrence and poor survival. In this study, we analyzed several factors affecting both survival and recurrence after hepatic resection. PATIENTS AND METHODS From October 1995 to April 2007, 550 patients underwent hepatic resections, of which, 175 patients had HCC in cirrhotic liver in Gastroenterology Surgical Center, Mansoura University, Egypt. There were 131 males (74.9%) and 44 females (25.1%) with a mean age of 54.8 +/- 9.2 years (ranges from 26 to 75 years). RESULTS Most of our patients were in Child's Pugh class A (86.9%). Major hepatic resection was done for 65 patients (37.1%), segmentectomy was done for 62 patients (35.4%), and localized resection was done for 48 patients (27.4%). Hospital mortality occurred in 16 (9.1%) patients, while hospital morbidity occurred in 40% of patients. The 1, 3, and 5 years survival were 68.6%, 29.6%, and 10.7%, respectively. The prognostic factors affecting recurrence were multifactorial, and the univariate analysis showed that multifocality of the tumor (p = 0.006), capsule (p = 0.001), staging (p = 0.001), blood transfusion (p = 0.02), infiltration of the cut margin (p = 0.001), vascular invasion (p = 0.006), and lymph nodes infiltration (p = 0.014) affect the recurrence rate, while with multivariate analysis, only cut margin was significantly affecting the recurrence (p = 0.026). Also, factors that significantly predicted survival were preoperative serum albumin (p = 0.005), tumor differentiation (p = 0.008), staging (p = 0.001), tumor's capsule (p = 0.001), cut margin (p = 0.031), vascular invasion (p = 0.049), and operative blood transfusion (p = 0.001). However, tumor differentiation (p = 0.048) was the only independent factor on multivariate analysis affecting long-term survival. CONCLUSION In our experience, the prognostic factors after resection for recurrence and survival are different and multifactorial. However, resection of HCC in cirrhotic liver with preserved liver function is the treatment of choice in the present time and can be done with favorable results.

Abstract
PURPOSE Classical anatomical resection does not always guarantee tumor-free margins when the tumor overrides traditional anatomical planes. Surgeons and interventionists frequently need to focus on the peripheral branches of Glisson's sheath in patients with poor hepatic reserves, particularly when the tumor is deep seated. The present study used anatomical liver dissection to investigate the spatial distribution of the branches of Glisson's sheath in each of four liver sectors. METHODS Sixty-four adult human liver specimens were dissected. The size and ramification patterns of Glisson's sheath in each sector were analyzed in terms of bilateral homology within two paramedian sectors and within two lateral sectors. RESULTS Each liver sector had a characteristic Glisson's sheath in terms of trunk shape and ramification pattern. The two paramedian sectors showed point symmetry. Most of the branches of the two paramedian sectors emerged from the top of a short stout trunk. Although the two paramedian sectors were similar in terms of basic configuration, the ramification axes were almost perpendicular to each other. Unlike the paramedian sectors, the two lateral sectors showed not much homology. CONCLUSIONS The peripheral branches of Glisson's sheath were generally longer (approximately 5 cm) and thicker than anticipated. Extirpation strategies should take into account that each liver sector has a characteristic Glisson's sheath ramification pattern.

Abstract
PURPOSE Characteristics of hepatocellular carcinoma (HCC) complicating nonalcoholic steatohepatitis (NASH) are still controversial. Most NASH related HCCs are believed to develop from cirrhotic liver, but case reports about HCC arising from non-cirrhotic NASH have been accumulating recently. This study is designed to elucidate characteristics of NASH related HCC diagnosed with high accuracy by using surgically resected specimens that contain larger areas to validate than biopsy specimens. METHODS For this study, 1168 patients who underwent hepatic resection at Osaka Medical Center for Cancer and Cardiovascular Diseases were enrolled. Patients who had clinically obvious causes of chronic liver dysfunction, such as viral and alcoholic hepatitis, were excluded. Histological diagnosis of NASH was confirmed according to Brunt's criterion. RESULTS Eight (1%) patients were diagnosed with NASH. Six (75%) of them showed non-cirrhosis in non-cancerous areas. Stages of fibrosis in the non-cirrhotic patients were mild fibrosis (F2) in five and moderate fibrosis (F3) in one. All patients complicated with metabolic diseases. Although all these patients without cirrhosis were evaluated pathologically at tumor-node-metastasis stages I or II, three (50%) had multiple recurrences of tumor within a short time after surgery. CONCLUSION This study indicates HCC might arise frequently from non-cirrhotic NASH. While further studies are needed to confirm this observation, both cirrhotic and non-cirrhotic NASH warrant regular screening for HCC.

Abstract
Hepatocellular carcinoma (HCC) is an aggressive malignancy mainly due to tumor metastases or recurrence even after undergoing potentially curative treatment. There are two types of HCC recurrence. The early and late tumor recurrences appear in distinct biological contexts, and their clinical courses are quite different. Therefore, it is important to precisely and distinctly discriminate the risk of each type of HCC recurrence. Many researchers have used DNA microarray technology to reclassify HCC with respect to its malignant potential. Some of these studies successfully identified specific gene-expression signatures derived from the cancerous tissues of HCC for predicting the early recurrence due to intrahepatic metastasis. However, there are no well-defined predictors for late recurrence. Recently, a few studies have focused on the nontumorous portion of liver tissues to predict late recurrence, possibly due to de novo hepatocarcinogenesis based on the idea of "field cancerization." This study reviewed the possible value of a gene-expression analysis of noncancerous liver tissue to clarify the risk for multicentric late recurrence of HCC. These findings may have important implications for chemopreventive strategies and tailored surveillance programs. Furthermore, this approach may also be applicable to other multifocal tumors, such as head and neck carcinoma.

Abstract
Hepatocellular carcinoma (HCC) is the fifth most common neoplasm and the third leading cause of cancer-related deaths worldwide. Cirrhosis, most often due to viral hepatitis, is the predominant risk factors for HCC and geographical differences in both risk factors and incidence are largely due to epidemiological variations in hepatitis B and C infection. Hepatic function is a relevant parameter in selecting therapy in HCC. The current clinical classification of HCC split patients into 5 stages, with a specific treatment schedule for any stage. As patients with early stages can receive curative treatments, such as surgical resection, liver transplantation or local ablation, surveillance program in high-risk populations has become mandatory. Sorafenib, a multikinase inhibitor, has recently shown survival benefits in patients at advanced stage of disease. Hopefully, new molecular targeted therapies and their combination with sorafenib or interventional and surgical procedures, should expand the therapeutic armamentarium against HCC.

Abstract
BACKGROUND & AIMS Hepatic encephalopathy (HE) is associated with a poor prognosis. Lactulose is used for the treatment of HE. There is no study on the prevention of recurrence of HE using lactulose. METHODS Consecutive cirrhotic patients who recovered from HE were randomized to receive lactulose (HE-L group) or placebo (HE-NL group). All patients were assessed by psychometry (number connection test [NCT-A and B], figure connection test if illiterate [FCT-A and B], digit symbol test [DST], and object assembly test [OAT]), critical flicker frequency test, and blood ammonia at inclusion. Primary end point was development of overt HE. RESULTS Of 300 patients with HE who recovered, 140 (46.6%) met the inclusion criteria and were included. There was a high prevalence of abnormal psychometry test results (NCT-A, 67.5%; NCT-B, 62.5%; DST, 70%; and OAT, 80%), and FCT-A and B were abnormal in 10 of 14 patients. Critical flicker frequency was <38 Hz in 77 patients (55%). Twelve (19.6%) of 61 patients in the HE-L group and 30 (46.8%) of 64 in the HE-NL group (P = .001) developed HE over a median follow-up of 14 months (range, 1-20 months). Readmission rate due to causes other than HE (HE-L vs HE-NL, 9:6; P = NS) and deaths (HE-L vs HE-NL, 5:11; P = .18) in 2 groups were similar. Recurrence of overt HE was significantly associated with 2 or more abnormal psychometric tests after the recovery of an episode of HE (r = 0.369, P = .02). CONCLUSIONS Lactulose is effective for prevention of recurrence of HE in patients with cirrhosis.

Abstract
AIM: To examine the immunoreactivity of E-cadherin and four subtypes of catenin family in human hepatocellular carcinomas (HCCs) and to investigate the correlation between expression of E-cadherin/catenin complex and clinicopathologic parameters of HCC patients.
METHODS: An immunohistochemical study for E-cadherin and catenins was performed on 97 formalin-fixed, paraffin-embedded specimens of HCC.
RESULTS: Reduced expression of E-cadherin, α-, β-, γ-catenin and p120 was observed in 69%, 76%, 63%, 71% and 73%, respectively. Both expressions of E-cadherin and catenin components were significantly correlated with tumor grade (P = 0.000). It showed significant difference between expression of catenin members and tumor stage (P = 0.003, P = 0.017, P = 0.007 and P = 0.000, respectively). The reduced expression of E-cadherin in HCCs was significantly correlated with intrahepatic metastasis (IM) and capsular invasion (P = 0.008, P = 0.03, respectively). A close correlation was also observed between the expression of catenins and the tumor size (P = 0.002, P = 0.034, P = 0.016 and P = 0.000, respectively). In addition, the expression of each catenin was found correlated with IM (P = 0.012, P = 0.049, P = 0.026 and P = 0.014, respectively). No statistically significant difference was observed between the expression level of E-cadherin/catenin complex and lymph node permission, vascular invasion and satellite nodules. Interestingly, only expression of p120 showed correlation with AFP value (P = 0.035). The expression of E-cadherin was consistent with α-, β-, γ-catenin and p120 expression (P = 0.000). Finally, the abnormal expression of E-cadherin/catenin complex was significantly associated with patients’ survival (P = 0.0253, P = 0.0052, P = 0.003, P = 0.0105 and P = 0.0016, respectively). Nevertheless, no component of E-cadherin/catenin complex was the independent prognostic factor of HCC patients.
CONCLUSION: Down-regulated expressions of E-cadherin, catenins and p120 occur frequently in HCCs and contribute to the progression and development of tumor. It may be more exact and valuable to detect the co-expression of E-cadherin/catenin complex than to explore one of them in predicting tumor invasion, metastasis and patient’s survival.

Abstract
BACKGROUND Although a second hepatic resection (SHR) for recurrent hepatocellular carcinoma (HCC) is widely accepted, the indications for SHR have not been established. The risk factors for HCC recurrence after SHR were evaluated to investigate the indications for SHR. METHODS Subjects included 51 patients who underwent a second hepatic resection for recurrence of HCV-related HCC. Sixteen patients received interferon therapy before or after the first operation. Six patients attained a sustained viral response (SVR) that was defined as return of the alanine aminotransferase (ALT) activity to within the reference range and no detectable serum HCV RNA for at least 1 year after interferon therapy. A biochemical response (BR), defined as a normalized ALT activity for at least 1 year after interferon therapy with or without the transient disappearance of serum HCV RNA, was attained in three patients. The other seven patients were defined as the nonresponse (NR) group. RESULTS By univariate analysis, NR and lack of interferon therapy, high indocyanine green retention rate at 15 min (ICGR15), high aspartate aminotransferase activity, high ALT activity, large tumor, and multiple tumors were risk factors for HCC recurrence after SHR. By multivariate analysis, NR and lack of interferon therapy, high ICGR15, large tumor, and multiple tumors were independent risk factors. CONCLUSIONS Patients in whom active hepatitis has been controlled by interferon therapy are the best candidates for SHR. Interferon therapy should be recommended in patients undergoing resection of an HCV-related HCC because SHR can prolong life in SVR and BR patients.

Abstract
BACKGROUND The pathogenesis of frequent intrahepatic recurrence of hepatocellular carcinoma (HCC) after surgical resection or local ablation therapy remains uncertain. Risks and patterns of intrahepatic distant recurrence (IDR) of a single, primary HCC lesion after radiofrequency (RF) ablation were examined. METHODS Ninety patients with a single primary HCC lesion of less than 3 cm who had complete RF ablation were enrolled in the study. Risk factors for IDR and the patterns of IDR after RF ablation were analyzed. RESULTS The median follow-up was 37.4 months. IDR was observed in 44 (48.9%) patients. The cumulative rate of IDR was 10.4%, 52.5%, and 77.0% at 1, 3, and 5 years, respectively. Univariate analysis revealed that a pretreatment serum alpha-fetoprotein (AFP) level of > or =50 ng/ml (P = 0.0324), a des-gamma-carboxy prothrombin (DCP) level of > or =40 mAu/ml (P = 0.006), an ablative margin of <5 mm of the ablation zone (P = 0.0306), and a prothrombin time of <70% (P = 0.0188) were related to IDR. A multivariate stepwise Cox proportional hazards regression model revealed that pretreatment serum AFP and DCP level and the ablative margin were independent risk factors for IDR pretreatment. Serum DCP level > or = 40 mAu/ml (P = 0.025), local tumor progression (P = 0.011), and ablative margin < 5 mm (P = 0.024) were related to multiple IDR. CONCLUSIONS HCC patients with high serum AFP or DCP before RF ablation should be carefully followed up to monitor any IDR. A sufficient ablative margin in RF ablation for HCC is required to prevent IDR.

Abstract
BACKGROUND The optimal treatment for hepatocellular carcinoma (HCC) is surgical resection. However, only a small percentage of patients are operative candidates. The authors aimed to assess a novel operative combination of laparoscopic radiofrequency (LRF) with a selective intrahepatic vascular occlusion (SIHVO) to obtain an increased rate of total necrosis and a reduced rate of local HCC recurrences. METHODS For this study, 37 patients with HCC in liver cirrhosis were submitted to LRF with SIHVO. An LRF was indicated for patients not amenable to liver resection who evidenced at least one of the following criteria: severe impairment of the coagulation tests, large tumors (but <5 cm) or multiple lesions requiring repeated punctures, superficial lesions adjacent to visceral structures, deep-sited lesions with a very difficult or impossible percutaneous approach, and short-term recurrence of HCC after percutaneous loco-regional therapies. RESULTS Laparoscopic ultrasound identified seven new malignant lesions (19%) undetected by preoperative imaging. There was no operative mortality. Of the 37 patients, 31 experienced no complications (84%). Computed tomography (CT) evaluation 1 month after treatment showed that a complete response with 100% necrosis had been achieved for all the patients (100%). During the follow-up period (mean, 11.8 +/- 8.2 months), new malignant nodules developed in 14 patients (42%), and 36% of these recurrences were located in the same treated segment of the HCC. CONCLUSIONS The combined LRF and SIHVO procedure proved to be a safe and effective technique at least in the short and mid term. In fact, it permitted the treatment of lesions not treatable using the percutaneous approach with a complete clearance, and it had a low morbidity rate.

Abstract
AIM: To assess whether a 24-wk course of interferon (IFN) could prevent hepatocellular carcinoma (HCC) recurrence and worsening of liver function in patients with hepatitis C virus (HCV)-infected patients after receiving curative treatment for primary HCC.
METHODS: Outcomes in 42 patients with HCV infection treated with IFN-α, after curative treatment for primary HCC (IFN group), were compared with 42 matched curatively treated historical controls not given IFN (non-IFN group).
RESULTS: Although the rate of initial recurrence did not differ significantly between IFN group and non-IFN group (0%, 44%, 61%, and 67% vs 4.8%, 53%, 81%, and 87% at 1, 3, 5, and 7 years, P = 0.153, respectively), IFN group showed a lower rate than the non-IFN group for second recurrence (0%, 10.4%, 28%, and 35% vs 0%, 30%, 59%, and 66% at 1, 3, 5 and 7 years, P = 0.022, respectively). Among the IFN group, patients with sustained virologic response (SVR) were less likely to have a second HCC recurrence than IFN patients without an SVR, or non-IFN patients. Multivariate analysis identified the lack of SVR as the only independent risk factor for a second recurrence, while SVR and Child-Pugh class A independently favored overall survival.
CONCLUSION: Most intrahepatic recurrences of HCV-related HCC occurred during persistent viral infection. Eradication of HCV is essential for the prevention of HCC recurrence and improvement of survival.

Abstract
AIM: To assess the efficacy of low-dose intermittent interferon (IFN) therapy in patients with hepatitis C virus (HCV)-related compensated cirrhosis who had received curative treatment for primary hepatocellular carcinoma (HCC).
METHODS: We performed a prospective case controlled study. Sixteen patients received 3 MIU of natural IFN-alpha intramuscularly 3 times weekly for at least 48 wk (IFN group). They were compared with 16 matched historical controls (non-IFN group).
RESULTS: The cumulative rate of first recurrence of HCC was not significantly different between the IFN group and the non-IFN group (0% vs 6.7% and 68.6% vs 80% at 1- and 3-year, P = 0.157, respectively). The cumulative rate of second recurrence was not also significantly different between the IFN group and the non-IFN group (0% vs 6.7% and 35.9% vs 67% at 1- and 3-year, P = 0.056, respectively). Although the difference in the Child-Pugh classification score between the groups at initial treatment of HCC was not significant, the score was significantly worse at the time of data analysis in the non-IFN group than IFN group (7.19 ± 1.42 vs 5.81 ± 0.75, P = 0.0008). The cumulative rate of deviation from objects of any treatment for recurrent HCC was also higher in the non-IFN group than IFN group (6.7% and 27% vs 0 and 0% at 1- and 3-year, P = 0.048, respectively).
CONCLUSION: Low-dose intermittent IFN-alpha therapy for patients with HCV-related compensated cirrhosis after curative HCC treatment was effective by making patients tolerant to medical or surgical treatment for recurrent HCC in the later period of observation.

Abstract
In a previous study, we showed that levels of cell-free DNA (cfDNA) were significantly higher in sera of patients with hepatocellular carcinoma (HCC) associated with hepatitis C virus (HCV) than in sera of non-HCC patients with HCV. To confirm this finding, we analysed serum cfDNA levels in a cohort of 96 patients with HCV-related HCC and in 100 HCV carriers without known HCC. Again we found that serum cfDNA levels were significantly higher in HCC patients than in HCV carriers (115.9±98.3 vs 34.4±40.4 ng ml−1 (mean±s.d.), P<0.0001). Of 87 eligible patients who underwent curative hepatectomy, those with a high cfDNA level had a significantly shorter overall survival (OS) time than those in whom the cfDNA level was not high. Cox proportional hazards model showed the cfDNA level to be an independent prognostic factor for OS and cancer recurrence in distant organs. Our results suggest that the serum cfDNA level reflects the metastatic potential of HCV-related HCC and that it can be a useful predictive biomarker for distant metastasis after curative surgery.

Abstract
Hepatocellular carcinoma (HCC) is the fifth most common neoplasm, the major cause of death in patients with liver cirrhosis, and the third most common cause of cancer-related death in the world. The geographic distribution of HCC varies significantly and 80% of cases occur in developing countries (Far East and South Asia) where the prevalence of viral hepatitis is higher. The treatment of HCC is difficult because most patients are diagnosed when the tumour is in an advanced stage and is not amenable to potential curative therapy, thus prevention is the key to reducing HCC and its related morbidity and mortality. HCC is unique among cancers, occurring mostly in patients with a known risk factor. Ninety percent of HCCs develop in the context of chronic liver diseases and mainly in patients with cirrhosis. Viral hepatitis is the most common cause of HCC worldwide, followed by alcoholic liver disease (ALD) and other causes such as non-alcoholic fatty liver disease (NAFLD), genetic haemocromatosis (GH) and primary biliary cirrhosis in an advanced stage (III-V). In certain areas of the People’s Republic of China, exposure to aflatoxin and HBV infection are thought to be responsible for the extraordinary high risk of HCC. Substantial progresses in the prevention of virusl-related hepatitis (screening of blood units, use of disposable sanitary tools, HBV vaccination) have been achieved in developed countries, but in the same areas, alcohol- and dysmetabolism-related HCCs are emerging problems which require specific interventions in terms of public health measures. In developing countries, economic constraints limit the development of any program for the prevention of viral hepatitis transmission (including health education campaigns, healthcare politics, primary prevention and the improvement of hygienic and sanitary conditions). When viral liver disease is established, only a minority of patients are treated worldwide and benefit a possible preventive effect of medical treatment on HCC development. Thus the real contribution of medical treatment to HCC prevention in patients with chronic viral hepatitis is small. Great efforts are needed to identify more effective medical measures for primary and secondary prevention of HCC.

Abstract
OBJECTIVE To determine whether detection of hepatocellular carcinoma (HCC) cells by real-time quantitative RT-PCR targeting of alpha-fetoprotein mRNA (AFP mRNA) before or after curative hepatectomy predicts HCC recurrence and patient survival. SUMMARY BACKGROUND DATA The presence of cancer cells in peripheral blood and/or bone marrow in patients with malignant disease has been reported to correlate with outcome. METHODS Between July 2000 and June 2005, 136 consecutive HCC patients underwent primary curative hepatectomy. Bone marrow aspirated preoperatively, and peripheral blood samples collected before and after operation were subjected to real-time quantitative RT-PCR analysis using AFP mRNA as a target molecule. Median follow-up was 23 months (range, 6-54 months). Patient survival (PS), disease-free survival (DFS), and clinicopathologic features were compared between patients with positive and negative AFP mRNA. RESULTS Twenty-four patients died (22 from HCC). HCC recurred in 66 patients (hepatic in 37 [56.1%]; hepatic and remote in 17 [25.8%], and remote alone in 12 [18.2%]). Bone marrow was positive for AFP mRNA in 38 patients (27.9%) and negative in 98 (72.1%). One- and 3-year PS was 96.6% and 91.4%, respectively, with negative AFP mRNA versus 86.2% and 55.5%, respectively, with positive AFP mRNA (P < 0.0001). One- and 3-year DFS were 73.2% and 44.8%, respectively, with negative AFP mRNA versus 54.5% and 25.8%, respectively, with positive AFP mRNA (P = 0.0399). Portal vascular invasion, tumor size, multiple tumors, and tumor differentiation correlated with inferior PS and DFS on univariate analysis. On multivariate analysis, positive AFP mRNA was the most important risk factor for PS (P = 0.001) and DFS (P = 0.0165). In addition, positive AFP mRNA in peripheral blood after operation tended to predict reduced DFS. CONCLUSION AFP mRNA in the bone marrow and systemic circulation during the perioperative period predicts patient survival and recurrence after curative hepatic resection for HCC.

Abstract
BACKGROUND The Japan integrated staging (JIS) score is recognized to be useful in managing hepatocellular carcinoma (HCC). We evaluated the effects of the causative virus in patients stratified by this system. METHODS We compared clinicopathologic features, cumulative and tumor-free survival rates, and causes of death between 301 hepatitis C virus-positive patients (HCV group) and 60 hepatitis B virus-positive patients (HBV group). RESULTS Among patients with low JIS scores (0 or 1), the proportions of patients with high aspartate and alanine aminotranferase activities, moderate-to-severe active hepatitis, and with cirrhosis were significantly higher in the HCV than in the HBV group. Among patients with high JIS scores (2 to 4), the proportion with moderate-to-severe active hepatitis was also significantly higher in the HCV group. In patients with low JIS scores, those in the HCV group had significantly lower tumor-free and cumulative survival rates than those in the HBV group. Although no patient in the HBV group died of causes other than liver disease (HCC or hepatic failure), some patients in the HCV group died of causes other than liver disease. The proportion of patients who died because of HCC recurrence tended to be higher among patients with high JIS scores than among patients with a low JIS score. CONCLUSIONS The effects of viral status on survival outcomes are greatest in patients with JIS scores of 0 or 1.

Abstract
The natural history of hepatocellular carcinoma is variable. In many patients the tumor has a long-lasting subclinical incubation period and often grows as a solitary mass to a size at which it can be detected by ultrasound. In other patients, however, the onset of the tumor is multinodal with great variations in the growth rates. Prognostication of patients with hepatocellular carcinoma takes into account the size and number of tumor nodes and their relation to the portal veins, and the degree of liver impairment.

Abstract
AIMS To compare intratumorous microvessel density (MVD) and clinicopathological features in two different groups of hepatocellular carcinoma (HCC), namely: hepatitis B virus (HBV) related HCC (B-HCC) and HCV related HCC (C-HCC). METHODS Fifty consecutive cases each of B-HCC and of C-HCC were studied. Microvessel numbers were assessed by staining for the antigen CD34; in each case, three areas with the highest numbers of microvessels were counted in both the intratumorous and the surrounding non-tumorous tissue; the mean value represented the final MVD. RESULTS Patients with B-HCC were significantly younger than those with C-HCC (mean age, 60.1 (SD, 4.1) v 66.4 (4.3) years); no significant differences were seen for sex or Child's class distribution. The tumour diameter was larger in B-HCCs than in C-HCCs (mean, 5.6 (SD, 1.8) v 3.8 (1.8) cm). Tumour microsatellite formation was significantly higher in C-HCCs (12 v 4 cases). No differences were found for histological subtype, degree of differentiation, tumour encapsulation, and vascular invasion. The mean MVD value was significantly higher in tumorous (mean, 54 (SD, 13.8) v 38 (8.9)) and in the surrounding non-tumorous liver tissue (mean, 15 (SD, 4.3) v 7 (3.1)) of C-HCCs. CONCLUSIONS C-HCCs present as smaller tumours in older patients, with a higher incidence of tumour microsatellite formation and higher MVD values both in the tumorous and the non-tumorous areas, suggesting a link between HCV infection, angiogenesis, and hepatocarcinogenesis.

Abstract
We studied the pattern of intrahepatic micrometastases using large pathologic sections on liver resection specimens with ample resection margins from 113 patients with a solitary hepatocellular carcinoma (HCC). The liver tissues around the HCC were divided into proximal and distal areas according to the direction of the portal vein flow. These areas were further divided into zones based on fixed criteria. Altogether, 273 micrometastases were identified, including 254 (93.0%) intravascular micrometastases and 19 (7.0%) tumor satellite micronodules. The distance of spread of these micrometastases ranged from 0.05 to 6.10 cm. The number of micrometastases was less in the proximal area than in the distal area. In addition, the farther the distance away from the primary tumor, the fewer micrometastases there were. Micrometastases extended beyond the 2 cm margin in only nine (8.0%) patients. In conclusion, micrometastases could spread via invasion of portal vein branches at an early stage even when the tumor was solitary and small. Anatomic segment resection is preferred for patients with a solitary HCC. Nonanatomic resection may be used as an alternative in patients with impaired liver function, but adequate resection margins should be achieved. For HCCs < or = 3 cm, a proximal resection margin and a distal margin of 1.0 cm are recommended. For HCCs > 3 cm, a 1.0 proximal resection margin and a 2.0 cm distal margin are recommended.

Abstract
OBJECTIVE The purpose of this study was to evaluate prognostic factors in patients with recurrence after curative resection of hepatocellular carcinoma (HCC) and to identify selection criteria for repeat resection. SUMMARY BACKGROUND DATA Recent studies have demonstrated that repeat hepatectomy is effective for treating intrahepatic recurrent HCC in selected patients. However, the prognostic factors in these patients have not been fully evaluated. METHODS From October 1994 to December 2000, 334 patients underwent primary resection for HCC, and 67 received a 2nd hepatectomy for recurrent HCC. The survival results in these 67 patients were analyzed, and prognostic factors were determined using 38 clinicopathological variables. The prognosis and operative risk in 11 and 6 patients who received a 3rd and 4th resection were also evaluated. RESULTS The overall 1-, 3-, and 5-year survival rates of the 334 patients after primary hepatectomy were 94%, 75%, and 56%, while those of the 67 patients after a 2nd resection were 93%, 70%, and 56%, respectively. There was no difference in survival (P = 0.64). All of the patients who underwent a 3rd or 4th are currently alive at a median follow-up of 2.5 and 1.4 years, respectively. The operative time and blood loss in the 2nd resection in patients who underwent a major primary resection were not different from those in patients who underwent minor hepatectomy at the 1st resection, and there were also no differences in these variables among the 2nd, 3rd, and 4th resections. In a multivariate analysis, absence of portal invasion at the 2nd resection (P = 0.01), single HCC at primary hepatectomy (P = 0.01), and a disease-free interval of 1 year or more after primary hepatectomy (P = 0.02) were independent prognostic factors after the 2nd resection. Twenty-nine patients with all 3 of these factors showed 3- and 5-year survival rates of 100% and 86%, respectively, after the 2nd resection. CONCLUSIONS Repeat hepatic resection is the treatment of choice for patients who have previously undergone resection of a single HCC at the primary resection and in whom recurrence developed after a disease-free interval of 1 year or more and the recurrent tumor had no portal invasion.

Abstract
OBJECTIVE To evaluate prognostic factors that could affect disease-free survival and recurrence after liver resection for hepatocellular carcinoma (HCC) on cirrhosis. SUMMARY BACKGROUND DATA Tumor recurrence is the main cause of poor survival after liver resection for HCC on cirrhosis. METHODS Two hundred twenty-four liver resections for HCC on cirrhosis were retrospectively reviewed. Univariate and multivariate analyses were performed on several clinicopathologic variables to analyze factors affecting long-term outcome and intrahepatic recurrence. The relation between preoperative aminotransferase level and recurrence rate was evaluated in the overall group, and separately in HCV-positive and in HBsAg-positive patients. Median follow-up was 35.6 months. RESULTS The 1-, 3-, and 5-year overall survival rates were 83%, 62.8%, and 42.5%, respectively. The 1-, 3-, and 5-year disease-free survival rates were 70.3%, 43%, and 27.4%, respectively. The 1-, 3-, and 5-year recurrence rates were 20.8%, 38.6%, and 54.4% respectively. Tumor recurrence appeared in 93 patients (41.5%) and was the main cause of death in 51 patients (56%). Number of nodules, tumor capsule, microvascular portal vein thrombosis, and preoperative serum aspartate aminotransferase (AST) level significantly affected disease-free survival and recurrence rates. On multivariate analysis, single nodules and preoperative AST level less than twice normal (2N) were related to a better 5-year disease-free survival and lower tumor recurrence. In particular, among HCV-positive patients the recurrence rate was strongly affected by the preoperative AST level. CONCLUSIONS Child A patients with single nodules are the best candidates for liver resection. Tumor recurrence is strictly linked to the status of the underlying liver disease, and a preoperative AST level equal to 2N seems to be a sensitive cutoff among patients with different risks of recurrence. HCV-positive patients with AST levels above 2N have the highest risk for intrahepatic recurrence and should be monitored carefully or offered alternative treatments.

Abstract
We examineded the clinical effects of serum hepatitis B e antigen (HBeAg) positivity on clinicopathologic findings and prognosis after liver resection for hepatocellular carcinoma (HCC) in patients with chronic hepatitis B. A series of 56 patients who underwent curative resection were divided into two groups: 25 HBeAg-positive patients (group 1) and 31 HBeAg-negative patients (group 2). The mean age was significantly lower in group 1 than in group 2 (p = 0.0021), and the proportion of patients with symptoms was significantly higher in group 1 than in group 2 (p = 0.037). There were no significant differences in other clinical findings between the two groups, including laboratory test results, coexisting medical conditions, and operative methods. Although tumor size, degree of differentiation of the main tumor, and the prevalence of vascular invasion did not differ between the groups, the prevalence of intrahepatic metastasis and the proportion of patients with active hepatitis were significantly higher in group 1 than in group 2 (p = 0.009 and p = 0.043, respectively). Tumor-free and cumulative survival rates were significantly lower in group 1 than in group 2 (p = 0.022 and p = 0.0001, respectively). Multivariate analysis of various possible risk factors demonstrated serum HBeAg positivity to be an independent risk factor for recurrence [risk ratio (RR) 2.49; 95% confidence interval (CI) 1.12-5.49; p = 0.032] and an independent unfavorable factor for the survival time (RR 7.58; 95% CI 2.10-27.8; p = 0.0020). We concluded that the prognosis after liver resection for HCC is worse for HBeAg-positive patients than for HBeAg-negative patients.

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
OBJECTIVE To evaluate the influence of the width and histologic involvement of the resection margin on postoperative recurrence after resection of hepatocellular carcinoma (HCC). SUMMARY BACKGROUND DATA The significance of the resection margin in hepatectomy for HCC remains controversial. A precise evaluation of the effects of the width and histologic involvement of the resection margin on postoperative recurrence is required to clarify the issue. METHODS Two hundred eighty-eight patients with macroscopically complete resection of HCC were divided into groups with narrow (<1 cm) or wide (>/=1 cm) resection margins. The two groups were compared for postoperative recurrence rate and pattern of recurrence. A further analysis was performed to investigate the effects of histologic involvement of the resection margin on postoperative recurrence. RESULTS Recurrence rates were similar between 150 patients with a narrow margin and 138 patients with a wide margin; the groups were comparable in other clinicopathologic variables. Most recurrent tumors occurred in the liver remnant at a segment distant from the resection margin or at multiple segments. Thirty-four patients had margin involved histologically by microscopic invasion from the main tumor (n = 13), venous tumor thrombi (n = 13), or microsatellites separate from the main tumor (n = 8). These patients had significantly higher recurrence rates than those with a histologically clear margin. However, a positive histologic margin was not a significant risk factor for recurrence by multivariate analysis. Tumor stage and perioperative transfusion were the only independent risk factors. CONCLUSIONS The width of the resection margin did not influence the postoperative recurrence rates after hepatectomy for HCC. A positive histologic margin was associated with a higher incidence of postoperative recurrence, but in most patients this was related to the underlying venous invasion or microsatellites. Most intrahepatic recurrences were considered to arise from intrahepatic metastasis by means of venous dissemination, which a wide resection margin could not prevent.

Abstract
Clinicopathologic findings in patients with hepatocellular carcinoma complicating hepatitis C virus and outcomes after liver resection were compared between different viral genotypes. One hundred and forty-seven patients with both anti-hepatitis C virus antibody and hepatitis C virus RNA in their sera underwent curative resection for hepatocellular carcinoma in our department between 1991 and 1997. Of these patients, 115 were infected with hepatitis C virus genotype 1b (group 1), and 32 were infected with 2a or 2b (group 2). Clinicopathologic findings and outcomes after operation were compared between the two groups. Alanine aminotransferase activity was significantly higher in group 2 than in group 1. Genotypes did not differ concomitantly with histopathologic features of the carcinoma or adjacent hepatic tissue. Although the tumor-free survival rate did not differ significantly between the two groups, recurrence was not detected during the period beyond 3 years following operation in group 2, while recurrences arose during that period in 16 group 1 patients, most of whom continued to manifest active hepatitis. In 7 of these 16 patients, the recurrent tumors were histologically multicentric in origin. The cumulative survival rate was significantly lower in group 1 than 2. Multivariate analysis indicated that genotype 1b was an independent risk factor for short survival. Patients infected with genotype 1b may have a relatively high risk of ongoing hepatocarcinogenesis and more aggressive progression of associated liver dysfunction, resulting in a poorer outcome than with other genotypes.

Abstract
Intrahepatic metastasis is one of the malignant features of hepatocellular carcinoma (HCC). Matrix metalloproteinases (MMPs) and urokinase-type plasminogen activator (u-PA)/plasmin, are known to be associated with the invasive properties of various types of tumor cells. In this study, we examined which proteinases play a role in the metastatic invasion of human HCC cell lines. JHH-5 and JHH-6 cells constitutively expressed mRNAs for both membrane-type 1 matrix metalloproteinase (MT1-MMP) and u-PA and invaded through reconstituted MATRIGEL in vitro, whereas JHH-7 cells expressed u-PA mRNA but not MT1-MMP and did not invade. However, hepatocyte growth factor (HGF) induced MT1-MMP expression on the surface of JHH-7 cells and markedly increased invasiveness of JHH-7 in a concentration-dependent manner. Moreover, cleavage activity for pro-MMP-2 was induced in HGF-treated JHH-7 cells. MMP inhibitor, rather than serine proteinase inhibitor, potently inhibited HCC cell invasion. Intrahepatic injection of HCC cell lines into athymic nude mice caused visible intrahepatic metastases in vivo. Moreover, JHH-7 tumors showed expression of MT1-MMP mRNA, while in vitro cultured JHH-7 cells did not. These findings suggest that MT1-MMP plays an important role in the invasive properties of HCC cells, and that HGF modifies the invasive properties of noninvasive HCC cells.

Abstract
The relationship between multicentric occurrence of hepatocellular carcinoma (HCC) and the histology of noncancerous hepatic tissue was investigated in 252 patients infected with hepatitis C virus (HCV) and surgically treated for HCC. One type of multicentric HCC had at least one tumor consisting of well-differentiated HCC, together with moderately or poorly differentiated HCC located in a separate region. The other type had an area of well-differentiated component around HCC with less differentiation in all occurrences. Noncancerous hepatic tissues were assessed using a histologic activity index score. Serum alanine aminotransferase (ALT) activity, the concentration of type 4 collagen, the grading score (severity of active hepatitis), and the staging score (degree of fibrosis) were significantly higher in patients with multicentric HCCs than in those without them. Platelet count was significantly lower in patients with multicentric HCCs. The prevalence of multicentric HCCs increased as the grading score and staging score increased. On univariate analysis, a low platelet count and high grading and staging scores were risk factors for multicentric HCCs. A high ALT activity and a high concentration of type 4 collagen tended to be risk factors. On multivariate analysis, high grading score and high staging score were independent risk factors. These findings indicate that active hepatitis and extensive fibrosis are responsible for the development of multicentric HCCs. Measurement of platelet count, ALT activity, and the concentration of type 4 collagen, and histologic assessment of noncancerous hepatic tissue provide information useful for estimation of the potential for multicentric carcinogenesis.

Abstract
The effect of persistent hepatitis C viremia on the outcome after resection of hepatocellular carcinoma (HCC) was investigated in 59 consecutive patients with a single small HCC (< or = 3.0 cm in diameter). The presence of serum hepatitis C virus (HCV) RNA was evaluated using a reverse transcription polymerase chain reaction method as well as a branched DNA probe method. Clinicopathologic findings were compared between patients with and without viremia and the risk factors for poor outcome were evaluated. Hepatitis C virus (HCV) RNA was not detected in the sera from 7 patients (group 1), but was detected in the sera from the other 52 patients (group 2). Alanine aminotransferase (ALT) activity was significantly higher in group 2 than in group 1. The proportion of patients with active hepatitis was significantly higher in group 2. In group 2, new HCC often developed after the operation and four patients died of liver dysfunction. HCV viremia, high ALT activity, high concentration of total bilirubin, and liver cirrhosis were related to recurrence after the operation. Multivariate analysis indicated that HCV viremia and high ALT activity were independent risk factors for recurrence of HCC. Continuous hepatitis with persistent HCV viremia worsened the outcome after the resection of HCC by causing new development of HCC and deterioration of liver function. In patients with HCV-related HCC, but without HCV viremia, satisfactory results can be expected after liver resection.

Abstract
OBJECTIVE This study aimed to evaluate the long-term results of treatment and prognostic factors in patients with intrahepatic recurrence after curative resection of hepatocellular carcinoma (HCC). SUMMARY BACKGROUND DATA Recent studies have demonstrated the usefulness of re-resection, transarterial oily chemoembolization (TOCE), or percutaneous ethanol injection therapy (PEIT) in selected patients with intrahepatic recurrent HCC. The overall results of a treatment strategy combining these modalities have not been fully evaluated, and the prognostic factors determining survival in these patients remain to be clarified. METHODS Two hundred and forty-four patients who underwent curative resection for HCC were followed for intrahepatic recurrence, which was treated aggressively with a strategy including different modalities. Survival results after recurrence and from initial hepatectomy were analyzed, and prognostic factors were determined by univariate and multivariate analysis using 27 clinicopathologic variables. RESULTS One hundred and five patients (43%) with intrahepatic recurrence were treated with re-resection (11), TOCE (71), PEIT (6), systemic chemotherapy (8) or conservatively (9). The overall 1-year, 3-year, and 5-year survival rates from the time of recurrence were 65.5%, 34.9%, and 19.7%, respectively, and from the time of initial hepatectomy were 78.4%, 47.2%, and 30.9%, respectively. The re-resection group had the best survival, followed by the TOCE group. Multivariate analysis revealed Child's B or C grading, serum albumin < or = 40 g/l, multiple recurrent tumors, recurrence < or = 1 year after hepatectomy, and concurrent extrahepatic recurrence to be independent adverse prognostic factors. CONCLUSIONS Aggressive treatment with a multimodality strategy could result in prolonged survival in patients with intrahepatic recurrence after curative resection for HCC. Prognosis was determined by the liver function status, interval to recurrence, number of recurrent tumors, any concurrent extrahepatic recurrence, and type of treatment.
