Comparison of clinicopathologic characteristics among patients with HBV-positive, HCV-positive and Non-B Non-C hepatocellular carcinoma after hepatectomy: a systematic review and meta-analysis. BMC Gastroenterol 2023; 23:289. [PMID: 37612653 PMCID: PMC10463328 DOI: 10.1186/s12876-023-02925-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/03/2022] [Accepted: 08/12/2023] [Indexed: 08/25/2023] Open
Abstract
BACKGROUND The incidence of HBV-negative and HCV-negative hepatocellular carcinoma (NBNC-HCC) is significantly increasing. However, their clinicopathologic features and prognosis remain elucidated. Our study aimed to compare the clinicopathologic characteristics and survival outcomes of NBNC-HCC with hepatitis virus-related HCC. METHOD A literature review was performed in several databases, including PubMed, Embase, Cochrane Library and Web of Science, to identify the studies comparing NBNC-HCC with HBV-positive HCV-negative HCC (B-HCC), HBV-negative HCV-positive (C-HCC) and/or HBV-positive HCV-positive HCC (BC-HCC). The clinicopathologic characteristics and survival outcomes were extracted and pooled to access the difference. RESULTS Thirty-two studies with 26,297 patients were included: 5390 patients in NBNC-HCC group, 9873 patients in B-HCC group, 10,848 patients in C-HCC group and 186 patients in BC-HCC group. Patients in NBNC-HCC group were more liable to be diagnosed at higher ages, but with better liver functions and lighter liver cirrhosis. Comparing to B-HCC and C-HCC groups, although NBNC-HCC group was prone to have larger tumor sizes, it did not have more advanced tumors. Meanwhile, there were no significant differences in both 5-year and 10-year disease-free survival and overall survival between NBNC-HCC group and B-HCC or C-HCC group. CONCLUSIONS Our meta-analysis revealed patients with NBNC-HCC had as worse prognosis as those with hepatitis virus-related HCC. More attention should be paid on patients with non-alcoholic steatohepatitis or metabolic syndromes to prevent the incidence of NBNC-HCC.

Long-Term Prognostic Factors after Hepatic Resection for Hepatitis C Virus-Related Hepatocellular Carcinoma, with a Special Reference to Viral Status. Liver Cancer 2018; 7:261-276. [PMID: 30319984 PMCID: PMC6170901 DOI: 10.1159/000486902] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2017] [Accepted: 01/17/2018] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND Although studies have reported on long-term (10-year) survival after hepatic resection for hepatocellular carcinoma (HCC), they did not focus on patients with hepatitis C virus (HCV)-related HCC, and the contribution of antiviral therapy to long-term survival (especially ≥15 years) has not been adequately examined. We investigated the long-term outcome after hepatic resection for HCV-related HCC, including the effects of interferon (IFN) therapy, and the changes in prognostic factors according to postoperative duration. METHODS The data of 207 patients who underwent hepatic resection for HCV-related HCC between January 1992 and December 2001 were retrospectively reviewed. We investigated the disease-free and overall survival rates after surgery and analyzed the prognostic factors at 5, 10, and 15 years postoperatively. RESULTS The proportion of patients who survived at 5, 10, and 15 years after hepatic resection was 52% (n = 107), 18% (n = 38), and 9% (n = 19). The overall survival rate was significantly higher in patients who achieved sustained virological response (SVR) with IFN therapy than in those without SVR. Tumor-related factors such as multiple tumor, microscopic vascular invasion, and a high indocyanine green retention rate at 15 min (ICGR15) were unfavorable prognostic factors for 5-year survival. Conversely, a low ICGR15 and SVR were favorable prognostic factors at 10 years, and SVR alone was a favorable prognostic factor at 15 years postoperatively; no tumor-related factors were prognostic factors at 10 and 15 years postoperatively. CONCLUSION The prognostic factors varied according to the duration after hepatic resection for HCV-related HCC. Tumor-related factors were unfavorable prognostic factors in the early postoperative period, whereas SVR and good liver function were favorable prognostic factors at 10 and 15 years postoperatively. Achievement of SVR with IFN therapy is essential for long-term (≥15 years) survival after hepatic resection for HCV-related HCC.

Abstract
BACKGROUND We investigated the patterns and predictors of recurrence and survival in cryptogenic non-B, non-C, non-alcoholic hepatocellular carcinoma (CR-HCC). We compared the findings with those hepatitis virus B (B) and hepatitis virus C (C)-HCC. CR-HCC does not include HCC developed on NASH. METHODS From 1990 to 2011, of 676 patients who underwent primary curative liver resection as initial therapy for HCC at our institution, 167 had B-HCC, 401 had C-HCC, and 62 had CR-HCC. Differences between three groups were analyzed using the Chi-squared test. Cumulative overall survival (OS) and disease-free survival (DFS) were determined by the Kaplan-Meier method, prognostic factors involved in OS/DFS were evaluated by univariate analysis using the log-rank test, and stepwise Cox regression analysis. RESULTS Liver function was better in CR-HCC than in B/C-HCC, and mean tumor size was larger in CR-HCC than in B/C-HCC. In CR-HCC, OS was equivalent to that of B/C-HCC, and DFS was equivalent to that of B-HCC. Both tumor-related factors and background liver function appeared to be prognostic factors for three groups. CONCLUSION Our findings indicate that the probability of survival of advanced CR-HCC was not longer than that of B/C-HCC. Given our findings, a postoperative follow-up protocol for CR-HCC should be established alongside that for B/C-HCC.

Abstract
Backgrounds/Aims Intrahepatic recurrence is one of the most important causes of compromised prognosis after surgical resection of hepatocellular carcinoma (HCC). This retrospective study was designed to identify and compare the risks of recurrence, early recurrence and multiple recurrences in a single patient population. Methods A series of 92 consecutive patients, who received resection for single nodular HCC at our institute from January 2007 to December 2013, were enrolled in this study. The patients were divided into recurrent and non-recurrent groups; the recurrent group was further divided into subgroups by applying two criteria: early and late recurrence (with a cutoff of 18 months), and single and multiple (≥2) recurrence. The potential risk factors were compared using univariate and multivariate analyses. The subgroup analysis was performed to determine the effects of different cut-off values on the analysis. Results 41 recurrences (44.6%) occurred during a mean follow-up of 42.4 months. The Child-Pugh score, and the portal vein invasion were found to be independent risk factors of recurrence, but differentiation was the only independent risk factor of early recurrence. The serum alpha-fetoprotein, tumor size, tumor necrosis, and hemorrhage were found to be the risk factors of multiple recurrences according to the univariate analysis, but lacked significance according to the multivariate analysis. When the cutoffs for early and multiple recurrences were changed to ≤10 months and >3 nodules, respectively, different risk factors were identified. Conclusions Our results implicated that different factors can predict the recurrence, timing, and multiplicity of an HCC recurrence. Further studies should be conducted to prove the complex relationships between tumor burden, invasiveness, and underlying liver cirrhosis for initial tumors, and the timing and multiplicity of recurrent HCC.

Abstract
BACKGROUND Surgical resection is an important curative treatment for hepatocellular carcinoma (HCC); however, some patients experience an unexpected recurrence even after hepatectomy. The present study aimed to investigate risk factors and predictive criteria for early and late recurrence of HCC after resection. METHODS A retrospective analysis of 398 Chinese patients who received curative resection for HCC was conducted. Patients were divided into three groups: without recurrence, early recurrence, and late recurrence. Prognostic factors and predictive criteria for early and late recurrence were statistically analyzed. RESULTS The cumulative recurrence-free survival rates at 1, 2, 3, 4, and 5 years were 75.5%, 58.2%, 54.1%, 40.5%, and 28.7%, respectively. The distribution of the time to recurrence suggested that recurrence could be divided into early phase (before 2 years; n=164) and late phase (after 2 years; n=83). Cox's multivariate proportional hazard model analysis revealed that multiplicity of tumors (P=0.004) and venous infiltration (P=0.002) were independent risk factors associated with early recurrence. In contrast, indocyanine green retention rate at 15 minutes (P=0.007), serum albumin level (P=0.045), and HBeAg status (P=0.028) proved to be significant independent adverse prognostic factors for late recurrence. Patients with at least 1 of the 2 early recurrence risk factors (multiplicity of tumors ≥ 2 and venous infiltration) or with 2 or more late recurrence risk factors are often susceptible to recurrence (P=1.36e-4 and 1.0e-6, respectively). CONCLUSIONS Early and late recurrences correlate with different risk factors and predictive criteria. Early recurrence primarily results from intrahepatic metastases, while late recurrence may be multicentric in origin.

Clinicopathological factors affecting survival and recurrence after initial hepatectomy in non-B non-C hepatocellular carcinoma patients with comparison to hepatitis B or C virus. BIOMED RESEARCH INTERNATIONAL 2014; 2014:975380.

Abstract
We evaluated clinicopathological factors affecting survival and recurrence after initial hepatectomy in non-B non-C (NBNC) hepatocellular carcinoma (HCC) patients with comparison to hepatitis B or C virus, paying attention to relationship between alcohol consumption and histopathological findings. The medical records on the 201HCC patients who underwent initial hepatectomy between January 2000 and April 2013 were retrospectively reviewed. NBNC patients had higher prevalence of hypertension (47.4%), diabetes mellitus (35.5%), alcohol consumption (>20 g/day) (61.8%), and preserved liver function than hepatitis B or C patients. The 5-year survival rate of NBNC patients (74.1%) was significantly better than hepatitis B (49.1%) or C (65.0%) patients (NBNC versus B, P = 0.031). Among the NBNC patients, there was no relationship between alcohol consumption and clinicopathological findings including nonalcoholic fatty liver disease activity score (NAS). However, the 5-year OS and RFS rates in the alcohol-unrelated NBNC patients tend to be better than in the alcohol-related. By multivariate analysis, independent factors for OS in NBNC patients were Child-Pugh B/C, intrahepatic metastasis (im), and extrahepatic recurrence. NBNC patients, who were highly associated with lifestyle-related disease and preserved liver function, had significantly better prognosis compared to hepatitis B/C patients; however, there was no association between alcohol consumption and histopathological findings.

Abstract
OBJECTIVE To examine the prognostic factors and outcomes after several types of treatments in patients with hepatocellular carcinoma (HCC) negative for hepatitis B surface antigen and hepatitis C antibody, so-called "non-B non-C HCC" using the data of a nationwide survey. BACKGROUND The proportion of non-B non-C HCC is rapidly increasing in Japan. METHODS A total of 4741 patients with non-B non-C HCC, who underwent hepatic resection (HR, n = 2872), radiofrequency ablation (RFA, n = 432), and transcatheter arterial chemoembolization (TACE, n = 1437) as the initial treatment, were enrolled in this study. The exclusion criteria included extrahepatic metastases and/or Child-Pugh C. Significant prognostic variables determined by a univariate analysis were subjected to a multivariate analysis using a Cox proportional hazard regression model. RESULTS The degree of liver damage in the HR group was significantly lower than that in the RFA and TACE groups. The HR and TACE groups had significantly more advanced HCC than the RFA group. The 5-year survival rates after HR, RFA, and TACE were 66%, 49%, and 32%, respectively. Stratifying the survival rates, according to the TNM stage and the Japan Integrated Staging (JIS) score, showed the HR group to have a significantly better prognosis than the RFA group in the stage II and in the JIS scores "1" and "2." The multivariate analysis showed 12 independent prognostic factors. HR offers significant prognostic advantages over TACE and RFA. CONCLUSIONS The findings of this large prospective cohort study indicated that HR may be recommended, especially in patients with TNM stage II and JIS scores "1" and "2" of non-B non-C HCC.

Abstract
BACKGROUND HCC is the fifth most common cancer globally. Our study was conducted to (1)investigate the trends and clinico-pathological characteristics of Hepatocellular carcinoma among native South Asian patients in Pakistan, (2)to estimate the prevalence as well as the trends of viral marker negative HCC and (3) to compare the clinico-pathological, radiological characteristics, applicability of treatment at diagnosis and prognostic factors among patients with both viral marker negative and viral marker positive-HCC being consulted at Aga Khan University Hospital(AKUH), Karachi, Pakistan. METHOD Patients ≥18 years, already diagnosed to have HCC and visiting AKUH during 1999-2009 were identified using ICD code 1550. The diagnosis of HCC was made in the presence of characteristic features of HCC on triple-phasic CT scan/MRI or with histological findings on biopsy. RESULTS 645 patients were enrolled. Of these 546(84.7%) were viral-HCC and 99(15.3%) were viral marker negative HCC. Among viral-HCC group underlying etiology of cirrhosis was HCV in 67.9%, HBV in 21.8% and concomitant HBV with HCV or HDV in 10.3% cases. Majority (62.8%) patients had advanced HCC. Larger tumor size (p < 0.001), shorter duration between diagnosis of cirrhosis and HCC (p 0.03), concomitant Diabetes Mellitus (p < 0.001) were found significant factors associated with viral marker negative HCC. CONCLUSION The burden of hepatocellular carcinoma is rising among native South Asian Pakistani population and the viral marker negative HCC are not uncommon in our population. Viral marker negative HCC tend not to be under surveillance as compared to viral-HCC and are diagnosed mostly at advanced stage & when they became symptomatic.

Abstract
Background The influence of viral hepatitis status on prognosis in patients undergoing hepatic resection for hepatocellular carcinoma (HCC) remains a matter of debate. This study is a meta-analysis of the available evidence. Methods A literature search was performed to identify comparative studies reporting postoperative survival of HCC in different types of viral hepatitis. Pooled odds ratios (OR) and weighted mean differences (WMD with 95% confidence intervals (95% CI) were calculated using either the fixed effects model or random effects model. Results Twenty studies matched the selection criteria and reported on 4744 subjects, of whom 2008 in the HBV-positive (B-HCC) group, 2222 in the HCV-positive (C-HCC) group, and 514 in the hepatitis B- and C-negative (NBNC-HCC). Meta-analysis showed that patients with HBV or HCV infection had a worse 5-year disease-free survival when compared to patients with NBNC-HCC (respectively: OR: 0.39, 95% CI: 0.28 to 0.53, P < 0.001; WMD: 0.37, 95% CI: 0.22 to 0.64, P < 0.001). There was a tendency toward higher 5-year overall survival rates in the NBNC-HCC group compared to those in the other two groups, although these differences were not statistically significant. Both the 5-year overall survival and disease-free survival were not different among the B-HCC and C-HCC groups. Conclusions Patients with positive serology for hepatitis B or C undergoing resection for HCC had a poor prognosis compared to patients with negative serology.

Abstract
BACKGROUND The present study investigated outcomes following surgical resection of hepatocellular carcinoma (HCC) in nonalcoholic fatty liver disease (NAFLD). METHODS Patients (n = 225) undergoing resection for HCC were divided into three groups: hepatitis C viral group (n = 147), hepatitis B viral group (n = 61), and NAFLD group (n = 17). Clinicopathological characteristics and surgical outcomes were analyzed retrospectively. RESULTS Patients in the NAFLD group were older (P < 0.001), with a higher body mass index (P < 0.001) and larger tumors (P = 0.002) than patients who were positive for hepatitis viral markers. Eight patients in the NAFLD group were found to have nonalcoholic steatohepatitis (NASH) histologically. Postoperative morbidity and 30-day mortality rates were significantly higher in the NAFLD group (59% and 12%, respectively) than in the hepatitis C viral (31% and 0.7%, respectively) and hepatitis B viral (28% and 3.3%; P = 0.043 and P = 0.016, respectively) groups. All deaths in the NAFLD group were in patients with NASH-related cirrhosis who had undergone right hemihepatectomy. Survival after resection was comparable among the three groups (P = 0.391), but patients with NAFLD showed better disease-free survival on univariate (P = 0.048) and multivariate (P = 0.020) analyses. CONCLUSIONS Surgical resection may provide a survival benefit for patients with NAFLD-related HCC. Patients with NASH-related cirrhosis undergoing major hepatic resection should be treated carefully.

Abstract
SYNOPSIS Major liver resection prevents intrahepatic tumor recurrence in T2 hepatocellular carcinoma patients with microvascular invasion or daughter nodules. BACKGROUND AND OBJECTIVES There is no consensus on whether major or minor hepatectomy is better for hepatocellular carcinoma (HCC) patients. We investigated the outcomes of liver resection type in resectable HCC patients. METHODS Two hundred sixty-three HCC patients with Child-Pugh class A liver function who underwent curative hepatectomy were enrolled. Among them, 186 patients had pathologic stage T1 HCC and 77 had stage T2 HCC. Patients were also classed according to the type of resection (major or minor). Clinicopathologic characteristics and outcomes were compared. RESULTS Patients with T1 HCC who underwent major resection had a higher rate of blood transfusion than those who underwent minor resection (P < 0.001). The disease-free survival rate of T2 patients who underwent major resection was better than that of patients who underwent minor resection (P = 0.004). The overall survival rates of T1 and T2 HCC patients did not differ significantly between those with major or minor resection. CONCLUSIONS Major liver resection is recommended for T2 HCC patients with adequate remnant liver function because it results in a better disease-free survival rate than does minor resection in these patients. Minor liver resection is suggested for T1 HCC patients, except for those with a tumor sitting close to vessels, because it is associated with a low incidence of blood transfusion and a good survival rate.

High TSC22D3 and low GBP1 expression in the liver is a risk factor for early recurrence of hepatocellular carcinoma. Exp Ther Med 2011; 2:425-431.

Abstract
Recurrence after liver resection for hepatocellular carcinoma (HCC) is a major clinical problem, and prognostic markers for recurrence are urgently required. For 390 HCC cases, segmented linear regression analysis with two segments was performed, and the interval for the early and late recurrence groups was partitioned at the crosspoint (676 days). We investigated whether gene expression in non-tumorous tissues of remnant liver from 39 hepatitis C virus-positive HCC cases may be associated with early recurrence of this disease. By microarray analysis, 21 genes were identified as candidate recurrence-associated genes. Further gene expression analysis was performed, and the localization and expression of the gene products of these candidate genes were immunohistochemically evaluated. Low expression of the GBP1 gene and high expression of the TSC22D3 gene were significantly (both P=0.04) associated with the risk of early recurrence. Through backward step-wise multivariate logistic regression analysis for the 21 candidate genes, high expression of GBP1 reduced [odds ratio (OR)=0.20; 95% confidence interval (CI) 0.06-0.73, P=0.02] and high expression of TSC22D3 increased the risk of early recurrence (OR=19.6; 95% CI 1.14-337.2; P=0.04). Immunohistochemical analysis revealed that hepatocytes showed strong membranous expression for GBP1 in the late recurrence group, but weak membranous expression for GBP1 in the early recurrence group. TSC22D3 was frequently expressed in lymphocytes and in a few hepatocytes in tissues of the early recurrence group. Our observations suggest that the combination of the high expression of the TSC22D3 gene and low expression of the GBP1 gene in the non-tumorous tissue of the remnant liver is significantly associated with early recurrence after surgical resection of HCC.

Abstract
PURPOSE In the east countries, patients with hepatocellular carcinoma (HCC) are usually associated with varied degrees of liver cirrhosis, and anatomic resection is therefore limited to use, especially in those with severe liver cirrhosis. This study aims to evaluate the clinical value of non-anatomic resection in HCC patients with cirrhosis. METHODS Seventy-seven consecutive HCC patients with cirrhosis underwent non-anatomic liver resection in Tongji Hospital from January 2003 to December 2006. The clinical data, severity of liver cirrhosis, and survival rates of these patients were retrospectively evaluated, and the prognostic factors were analyzed. RESULTS One-, 2-, and 3-year overall and disease-free survival rates of this cohort of patients were 78%, 68%, 56%, and 66%, 58%, 55%, respectively. The hospital mortality and morbidity were 0% and 24.7%, respectively. The 1-, 2-, and 3-year overall survival rates were 85.7%, 77.1%, and 74.3% in the patients with mild cirrhosis, 81.5%, 63%, and 48.1% in the patients with moderate cirrhosis, and 60.0%, 53.3%, and 26.7% in the patients with severe cirrhosis, respectively. There was a significant difference among the patients with different grades of cirrhosis (P = 0.001). Multivariate and univariate analyses revealed that severity of cirrhosis, tumor diameter larger than 5 cm, and vascular invasion were independent prognostic factors. CONCLUSIONS Non-anatomic liver resection for HCC could yield comparable outcomes with anatomic resection in the patients with mild cirrhosis or tumors diameter smaller than 5 cm. Severity of cirrhosis is an independent factor worsening long-time survival. Non-anatomic resection is a safe and effective surgical modality in the treatment of HCC patients with cirrhosis.

Abstract
AIM: To investigate the effects of cyclin-dependent kinases on the invasion of human hepatocellular carcinoma SMMC-7721 cells in vitro and explore potential mechanisms involved.
METHODS: SMMC-7721 cells were divided into two groups: control group (untreated with roscovitine) and treatment group (treated with 32 μmol/L of roscovitine for 24 hours). The ell cycle distribution of SMMC-7721 cells was detected by flow cytometry. Cell invasion and motility were evaluated by Transwell chamber assay and wound healing assay, respectively. The mRNA expression of urokinase plasminogen activator (uPA) and matrix metalloproteinase 9 (MMP-9) was detected by reverse transcription-polymerase chain reaction (RT-PCR).
RESULTS: The percentage of SMMC-7721 cells in G0/G1 phase was significantly higher in the treatment group than in the control group (72.19% ± 0.47% vs 59.22% ± 0.54%, P < 0.05). The number of cells passing through the Transwell membrane was significantly lower in the treatment group than in the control group (71.40 ± 5.59 vs 149.60 ± 16.36, P < 0.05). Roscovitine treatment also significantly decreased cell motility (P < 0.05). RT-PCR analysis revealed that roscovitine treatment downregulated the expression of uPA mRNA expression but had no significant impact on MMP-9 mRNA expression.
CONCLUSION: Roscovitine treatment decreases the invasion and motility of SMMC-7721 cells possibly via a mechanism associated with changing cell cycle and downregulating uPA mRNA expression.

Abstract
BACKGROUND AND AIM Previous studies have reported different risk factors for early and late intrahepatic recurrence after resection of hepatocellular carcinoma (HCC). However, the prognostic significance of the risk factors for early and late recurrence has not been clarified. METHODS A total of 190 Hepatitis B surface antigen-positive patients who received curative resection for HCC were reviewed. We investigated prognostic factors for disease-free and overall survival after resection, and further analyzed the relationship between significant prognostic factors and risk factors for early (<or=14 months) and late (>14 months) intrahepatic recurrence. RESULTS The 5-year disease-free and overall survival rates were 43.9% and 71.5%, respectively. In multivariate analysis, adverse prognostic factors for disease-free survival were presence of serum HBeAg, perioperative transfusion, and the presence of portal vein invasion (PVI) and/or intrahepatic metastasis (IM). Multivariate analysis revealed that overall survival was associated with ICG R15, serum albumin, Edmondson-Steiner grade, and the presence of PVI and/or IM. Independent risk factors for early intrahepatic recurrence were perioperative transfusion and PVI and/or IM, whereas positivity for HBeAg was the only risk factor for late recurrence. In addition, post-recurrence survival in patients with late intrahepatic recurrence was completely comparable to that of patients who never experienced recurrence. CONCLUSIONS The presence of serum HBeAg, the risk factor for late intrahepatic recurrence did not affect overall survival after resection because late recurrence was relatively well controlled by current available treatments. To further improve long-term surgical outcomes, effective treatment and preventive methods for early intrahepatic recurrence should be investigated.

Abstract
BACKGROUND AND AIM The characteristics and prognosis of patients with hepatitis virus marker-negative hepatocellular carcinoma (HCC) is not fully elucidated in Japan. We investigated the characteristics and prognosis of HCC patients in whom no markers for hepatitis virus infection were detected, in comparison with those of HCC patients with hepatitis virus infection. METHODS Viral markers for hepatitis B and C virus (HBV and HCV) infection were measured in 1152 patients in whom initial HCC was diagnosed between 1991 and 2004. Patient characteristics, characteristics of HCC and survival were compared between patients in whom no marker was positive (viral marker-negative HCC) and those in whom chronic HBV or HCV infection was confirmed by viral markers (viral HCC). RESULTS Overall, 119 patients (10.3%) were shown to have viral marker-negative HCC. Hepatocellular carcinoma was detected under surveillance in a significantly smaller percentage of patients with viral marker-negative HCC than of patients with viral HCC (P < 0.0001). The tumor was significantly larger (P < 0.0001) and vascular invasion was significantly more prevalent (P = 0.0003) in patients with viral marker-negative HCC than in those with viral HCC. The survival rate of patients with viral marker-negative HCC was significantly lower than that of patients with viral HCC (P = 0.0378). CONCLUSION The patients with HCC in whom hepatitis viral infection had not been confirmed tended not to be under surveillance, resulting in the detection of HCC at more advanced stage and with a poorer prognosis. Efforts to identify patients without hepatitis virus infection who should be under surveillance for HCC will be necessary in the future.

Abstract
BACKGROUND Although both hepatitis B virus (HBV) and hepatitis C virus (HCV) infection are well recognized risk factors for hepatocellular carcinoma (HCC), little is known with respect to how HBV and HCV infection affect HCC recurrence in postoperative HCC Chinese patients. The objective of this study was to determine if differences exist in preoperative characteristics and postoperative HCC recurrence in patients with different HBV and HCV infection status. METHODS The study population consisted of 413 patients undergoing a curative resection at Tianjin Cancer Hospital for small HCC (< or =3 cm) from January 1997 to December 2003. The patients were divided into four groups: HCV only (n = 75), HBV only (n = 251), HBV and HCV (n = 33), and neither HBV nor HCV (NBNC, n = 54). The preoperative status and postoperative HCC recurrence were recorded. Survival analyses were used to assess the impact of HBV/HCV status on HCC recurrence. RESULTS Patients with HCV had a significant association with older age, lower mean preoperative platelet counts and albumin levels, higher mean prothrombin time, alanine aminotransferase and total bilirubin levels and multinodular tumors during diagnosis. Patients with HCV also had significantly less differentiated tumors and a higher incidence of vascular invasion and cirrhosis when compared to the other groups. During the follow-up, the HCV group showed a higher incidence of intrahepatic recurrence and multiple recurrent lesions than the other patients. CONCLUSIONS Patients with HCV infection tended to be older, and were characterized by more severe cirrhosis and higher incidence of tumor multicentricity. The statistically significant determinants for reoccurrence in patients with small HCC were HCV infection, presence of vascular invasion and multiple tumors.

Abstract
BACKGROUND AND AIM The activation of Rho proteins has been shown to lead to loss of polarity in cancer cells, as well as reorganization of the cytoskeleton and facilitation of cell motility, possibly resulting in their malignant potential. The clinicopathological significance of RhoA, however, is not yet well known in the case of hepatocellular carcinoma (HCC). This study evaluated the clinicopathological correlation of RhoA levels with HCC. METHODS The intratumor expression level of Rho was determined and compared with that in adjacent non-cancerous hepatic tissue using quantitative real time RT-PCR and Western blotting in 64 patients with HCC. Relationships between the level of RhoA and clinicopathological factors were examined. RhoA protein expression was confirmed by immunohistochemistry. RESULTS RhoA immunostaining was strong in malignant tissue whereas it was minimal in benign tissue. Tumor tissue of HCC patients demonstrated a copy number of RhoA mRNA that was well correlated with its protein level in each case and was significantly higher than that found in the corresponding non-cancerous liver tissue (P < 0.01). With regard to venous invasion, satellite lesions and advanced pTNM stage, the RhoA level tended to be higher in HCC than that seen in negative tissue (P < 0.05). CONCLUSIONS This is the first demonstration that the expression level of RhoA is correlated with tumor progression and metastasis in HCC. RhoA in tumor tissue might be expected to be not only a good candidate marker for invasive and proliferative tumor cells, but also a molecular target of these cells.

Abstract
SUMMARY BACKGROUND DATA Some previous studies demonstrated better survival after transplantation for small hepatocellular carcinoma (HCC) compared with resection, but the influence of differences in tumor invasiveness between transplanted and resected patients has not been studied. This study compared the tumor characteristics of patients with HCC within the Milan criteria treated by resection or transplantation, and elucidated their impact on long-term survival. PATIENTS AND METHODS Tumor characteristics and long-term survival of 204 cirrhotic patients with resection and 43 cirrhotic patients with transplantation for HCC within the Milan criteria were compared. A multivariate analysis was performed to determine the prognostic factors of survival in all patients with resection or transplantation. RESULTS Tumors in the transplanted group were associated with lower incidence of high-grade tumors, microscopic venous invasion, and microsatellite nodules. The overall 5-year survival was better in the transplantation group than the resection group (81% vs. 68%, P = 0.017). However, there were no significant differences in survival between the two groups when stratified according to presence or absence of venous invasion. Multivariate analysis showed that hepatitis C virus serology, tumor size, tumor number, and microscopic venous invasion, but not resection or transplantation, were of prognostic significance. CONCLUSIONS There were significant differences in tumor invasiveness in HCC treated by transplantation and resection as a result of selection bias, even in patients with the tumors fulfilling the Milan criteria. When the different tumor invasiveness was taken into account, there was no significant difference in the long-term survival after resection or transplantation.

Abstract
BACKGROUND This study aimed to evaluate the effect of anatomic resection on long-term outcomes in patients with pathologic T1-T2 (pT1-T2) hepatocellular carcinoma. METHODS A retrospective analysis of 158 consecutive patients who underwent either anatomic (n = 95) or nonanatomic (n = 63) resection for pT1-T2 hepatocellular carcinoma was conducted. Anatomic resection was defined as the complete removal of at least one Couinaud segment containing the tumor; nonanatomic resection was defined as removal of the tumor plus a rim of nonneoplastic liver parenchyma. The median follow-up time was 83 months. RESULTS Patients who underwent anatomic resection were characterized by lower prevalence of cirrhosis (P = .015), more favorable hepatic function (P = .001), larger tumor size (P = .029), and higher prevalence of vascular invasion (P = .008) compared with patients who underwent nonanatomic resection. Anatomic resection provided better survival (median survival time, 122 months) than nonanatomic resection (median survival time, 76 months; P = .0358). Patients who underwent anatomic resection had better disease-free survival (P = .0121). Anatomic resection independently improved both survival (hazard ratio, .46; P = .003) and disease-free survival (hazard ratio, .55; P = .008). When stratified for pT classification, the effectiveness of anatomic resection remained only in patients with pT2 tumors in terms of survival (P = .0012) and disease-free survival (P = .0004). CONCLUSIONS Anatomic resection independently improves long-term survival in patients with T1-T2 hepatocellular carcinoma, probably because of the clearance of venous tumor thrombi within the resected domain.

Abstract
OBJECTIVE We investigated clinical characteristics and surgical outcome of hepatocellular carcinoma in association with hepatitis viral status. No consensus exists concerning differences in surgical outcome in patients with hepatocellular carcinoma according to viral hepatitis status, especially those negative for hepatitis B virus surface antigen and antibody to hepatitis C virus. METHODS Clinicopathologic data were available for 39 hepatectomy patients with hepatocellular carcinoma who were negative for hepatitis B virus surface antigen and hepatitis C virus antibody. Clinical characteristics and surgical outcome were analyzed retrospectively and compared to those patients with positive hepatitis viral markers. RESULTS Patients negative for viral hepatitis markers were more likely to have large, advanced-stages tumors with relatively well-preserved liver function and had a lower incidence of intrahepatic recurrences (P = 0.009). The intrahepatic recurrence rate reached a plateau at approximately 3 years after resection in patients with negative viral markers, while it continued to increase steadily in patients positive for viral hepatitis markers. By multivariable analysis, the absence of viral hepatitis markers predicted a decreased rate of intrahepatic recurrence (relative risk, 0.222; P = 0.001). CONCLUSIONS Adequate surgical resection in hepatocellular carcinoma patients negative for viral markers offers a good survival benefit, regardless of the etiology of the hepatocellular carcinoma.

Abstract
BACKGROUND The relationship between the state of non-cancerous tissues in patients with hepatocellular carcinoma (HCC) who are negative for hepatitis B surface antigen (HBsAg), hepatitis B core antibody (HBcAb), and hepatitis C antibody (HCVAb) (NBNC-HCC) and the prognosis has not yet been resolved. METHODS We examined the clinicopathological features of these patients and performed statistical analysis for the prognosis of recurrence following curative hepatic resection. RESULTS Disease-free survival (DFS) revealed that only the degree of fibrosis was a significant prognostic factor (P = 0.0374). On the basis of the degree of fibrosis (New Inuyama Classification), patients with NBNC-HCC were divided into a non-fibrotic liver group (NF group; F0, n = 10) and a fibrotic liver group (FL group; F1-4, n = 34). The DFS rate in the NF group was significantly better than that in the FL group (P = 0.0408). In the NF group, only one patient recurred, while in the FL group, 21 patients had recurrences. In the FL group, intra-hepatic recurrence was frequently seen in both lobes within 2 years after the initial hepatic resection, while recurrences more than 2 years after the initial operation were mainly seen in the contralateral lobe. CONCLUSION Histological assessment of the degree of fibrosis in the non-cancerous regions of NBNC-HCC may be useful not only for the selection of the appropriate treatment but also for the prediction of postoperative prognosis.

Abstract
AIM: To determine which treatment modality - hepatectomy or percutaneous ablation - is more beneficial for patients with small hepatocellular carcinoma (HCC) (≤ 4 cm) in terms of long-term outcomes.
METHODS: A retrospective analysis of 149 patients with HCC ≤ 4 cm was conducted. Eighty-five patients underwent partial hepatectomy (anatomic in 47 and non-anatomic in 38) and 64 underwent percutaneous ablation (percutaneous ethanol injection in 37, radiofrequency ablation in 21, and microwave coagulation in 6). The median follow-up period was 69 mo.
RESULTS: Hepatectomy was associated with larger tumor size (P < 0.001), whereas percutaneous ablation was significantly associated with impaired hepatic functional reserve. Local recurrence was less frequent following hepatectomy (P < 0.0001). Survival was better following hepatectomy (median survival time: 122 mo) than following percutaneous ablation (median survival time: 66 mo; P = 0.0123). When tumor size was divided into ≤ 2 cm vs > 2 cm, the favorable effects of hepatectomy on long-term survival was seen only in patients with tumors >2 cm (P = 0.0001). The Cox proportional hazards regression model revealed that hepatectomy (P = 0.006) and tumors ≤ 2 cm (P = 0.017) were independently associated with better survival.
CONCLUSION: Hepatectomy provides both better local control and better long-term survival for patients with HCC ≤ 4 cm compared with percutaneous ablation. Of the patients with HCC ≤ 4 cm, those with tumors > 2 cm are good candidates for hepatectomy, provided that the hepatic functional reserve of the patient permits resection.

Abstract
BACKGROUND Carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1) is a negative regulator of tumor cell growth, and may function as a tumor suppressor. CEACAM1 expression is down-regulated with increasing histologic grade in a number of malignancies. The authors hypothesized that loss of CEACAM1 expression in hepatocellular carcinoma (HCC) cells may function as an adverse prognostic factor. METHODS A retrospective analysis was conducted of 139 consecutive patients who underwent resection for HCC, with a median follow-up period of 83 months. Immunohistochemistry of the resected specimens was conducted using a monoclonal anti-CEACAM1 antibody. CEACAM1 expression in HCC was classified into two categories: diffuse expression, characterized by positive staining throughout the tumor specimen, or loss of expression, in which there were distinct areas of negative staining within the tumor specimen. RESULTS Of the 139 patients, 113 were classified as having tumors with diffuse expression and 26 had loss-of-expression tumors. Loss of CEACAM1 expression was more frequent in tumor specimens with Edmondson-Steiner Grades III or IV (21 of 32 [66%]) than in tumor specimens with Grades I or II (5 of 107 [5%]; P < 0.001) and was always seen in areas with the highest histologic grade. Loss of CEACAM1 expression was significantly associated with large tumor size, multiplicity of the tumor, portal vein invasion, and satellite nodules and affected survival adversely, according to univariate (P < 0.0001) and multivariate analyses (relative risk, 5.737; P < 0.001). CONCLUSIONS Loss of CEACAM1 expression reflects aggressive tumor biology and thus indicates a poor prognosis for patients with HCC.

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.
