Xiong SP, Wang CH, Zhang MF, Yang X, Yun JP, Liu LL. A multi-parametric prognostic model based on clinicopathologic features: vessels encapsulating tumor clusters and hepatic plates predict overall survival in hepatocellular carcinoma patients. J Transl Med 2024; 22:472. [PMID: 38762511 PMCID: PMC11102615 DOI: 10.1186/s12967-024-05296-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2024] [Accepted: 05/11/2024] [Indexed: 05/20/2024] Open
Abstract
BACKGROUND Vessels encapsulating tumor clusters (VETC) is a newly described vascular pattern that is distinct from microvascular invasion (MVI) in patients with hepatocellular carcinoma (HCC). Despite its importance, the current pathological diagnosis report does not include information on VETC and hepatic plates (HP). We aimed to evaluate the prognostic value of integrating VETC and HP (VETC-HP model) in the assessment of HCC. METHODS A total of 1255 HCC patients who underwent radical surgery were classified into training (879 patients) and validation (376 patients) cohorts. Additionally, 37 patients treated with lenvatinib were studied, included 31 patients in high-risk group and 6 patients in low-risk group. Least absolute shrinkage and selection operator (LASSO) regression analysis was used to establish a prognostic model for the training set. Harrell's concordance index (C-index), time-dependent receiver operating characteristics curve (tdROC), and decision curve analysis were utilized to evaluate our model's performance by comparing it to traditional tumor node metastasis (TNM) staging for individualized prognosis. RESULTS A prognostic model, VETC-HP model, based on risk scores for overall survival (OS) was established. The VETC-HP model demonstrated robust performance, with area under the curve (AUC) values of 0.832 and 0.780 for predicting 3- and 5-year OS in the training cohort, and 0.805 and 0.750 in the validation cohort, respectively. The model showed superior prediction accuracy and discrimination power compared to TNM staging, with C-index values of 0.753 and 0.672 for OS and disease-free survival (DFS) in the training cohort, and 0.728 and 0.615 in the validation cohort, respectively, compared to 0.626 and 0.573 for TNM staging in the training cohort, and 0.629 and 0.511 in the validation cohort. Thus, VETC-HP model had higher C-index than TNM stage system(p < 0.01).Furthermore, in the high-risk group, lenvatinib alone appeared to offer less clinical benefit but better disease-free survival time. CONCLUSIONS The VETC-HP model enhances DFS and OS prediction in HCC compared to traditional TNM staging systems. This model enables personalized temporal survival estimation, potentially improving clinical decision-making in surveillance management and treatment strategies.

Macroscopic Characterization of Hepatocellular Carcinoma: An Underexploited Source of Prognostic Factors. J Hepatocell Carcinoma 2024; 11:707-719. [PMID: 38605975 PMCID: PMC11007400 DOI: 10.2147/jhc.s447848] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2023] [Accepted: 02/29/2024] [Indexed: 04/13/2024] Open
Abstract
The macroscopic appearance of a tumor such as hepatocellular carcinoma (HCC) may be defined as its phenotype which is de facto dictated by its genotype. Therefore, macroscopic characteristics of HCC are unlikely random but rather reflect genomic traits of cancer, presumably acting as a valuable source of information that can be retrieved and exploited to infer prognosis. This review aims to provide a comprehensive overview of the available data on the prognostic value of macroscopic characterization in HCC. A total of 57 studies meeting eligible criteria were identified, including patients undergoing liver resection (LR; 47 studies, 83%) or liver transplant (LT; 9 studies, 16%). The following macroscopic variables were investigated: tumor size (n = 42 studies), number of nodules (n = 28), vascular invasion (n = 24), bile duct invasion (n = 6), growth pattern (n = 15), resection margin (n = 11), tumor location (n = 6), capsule (n = 2) and satellite (n = 1). Although the selected studies provided insightful data with notable prognostic performances, a lack of standardization and substantial gaps were noted in the report and the analysis of gross findings. This topic remains incompletely covered. While the available studies underscored the value of macroscopic variables in HCC prognostication, important lacks were also observed. Macroscopic characterization of HCC is likely an underexploited source of prognostic factors that must be actively explored by future multidisciplinary research.

Abstract
Objectives Hepatic transection through an anterior approach is required to successfully complete anatomical hepatectomy for large liver malignancies. The liver hanging maneuver (LHM) is an alternative procedure for transection on an adequate cut plane and may reduce intraoperative bleeding and transection times. Material and Methods We examined the medical records of 24 patients with large liver malignancies (>5 cm) who had undergone anatomical hepatic resection with LHM (n= 9) or without LHM (n= 15) between 2015 and 2020. Patient demographics, preoperative hepatic function, surgical records, and post-hepatectomy outcomes were retrospectively compared between the LHM and non-LHM groups. Results The prevalence of tumors >10 cm was significantly higher in the LHM group than in the non-LHM group (p <0.05). Furthermore, LHM was significantly performed to right and extended right hepatectomies in the background normal liver (p <0.05). Although transection times did not significantly differ between the two groups, the amount of intraoperative blood loss was slightly lower in the LHM group than in the non-LHM group (1.566 mL vs. 2.017 mL), and blood transfusion was not needed for patients in the LHM group. Post-hepatectomy liver failure and bile leakage were not observed in LHM. However, the length of hospitalization was slightly shorter in the LHM group than in the non-LHM group. Conclusion LHM is useful for transecting an adequately cut plane in hepatectomy for liver tumors over 5 cm-in-size located on the right side and achieves better outcomes.

Abstract
PURPOSE The surgical margin for liver resection to treat hepatocellular carcinoma (HCC) is occasionally < 1 mm. This study determined the impact of a surgical margin < 1 mm [marginal resection (MR)] on the types of recurrence and the prognosis in solitary HCC. METHODS The data of 454 patients undergoing curative liver resection for solitary HCC in our institution were analyzed. The patients were divided into the MR (n = 90) and non-MR (n = 364) groups. The clinicopathological data and outcomes after liver resection were compared. A case-matching analysis using a propensity scoring method was also performed. RESULTS The recurrence-free survival was significantly and overall survival was marginally significantly lower in the MR group than in the non-MR group (p = 0.012-0.051, respectively). According to a multivariate analysis, MR was not a significant independent factor for recurrence-free survival (p = 0.056). After propensity score matching, there were no significant differences in the recurrence-free and overall survival between the two groups (p = 0.375-0.496, respectively). Furthermore, there were no significant differences in the intrahepatic recurrence patterns between the two groups before and after matching. CONCLUSION MR for solitary HCC might be sufficient in patients with a limited liver functional reserve.

Abstract
Hepatocellular carcinoma (HCC) is a heterogeneous disease and the second most common cause of cancer-related death worldwide. Marked developments in genomic technologies helped scientists to understand the heterogeneity of HCC and identified multiple HCC-related molecular subclasses. An integrative analysis of genomic datasets including 196 patients from The Cancer Genome Atlas (TCGA) group has recently reported a new HCC subclass, which contains three subgroups (iCluster1, iCluster2, and iCluster3). However, the transcriptional molecular characteristics underlying the iClusters have not been thoroughly investigated. Herein, we identified a more aggressive subset of HCC patients in the iCluster1, and re-clustered the TCGA samples into novel HCC subclasses referred to as aggressive (Ag), moderate-aggressive (M-Ag), and less-aggressive (L-Ag) subclasses. The Ag subclass had a greater predictive power than the TCGA iCluster1, and a higher level of alpha fetoprotein, microscopic vascular invasion, immune infiltration, isocitrate dehydrogenase 1/2 mutation status, and a worse survival than M-Ag and L-Ag subclasses. Global transcriptomic analysis showed that activation of hedgehog signaling in the Ag subclass may play key roles in tumor development of aggressive HCC. GLI1, a key transcriptional regulator of hedgehog signaling upregulated in the Ag subclass, was correlated with poor prognosis of HCC, and may be a potential prognostic biomarker and therapeutic target for Ag subclass HCC patients.

Abstract
Objective Microvascular invasion (MVI) has been proved to be an independent risk factor for the recurrence of HCC. If promptly treated, the recurrence rate can be reduced and the total survival time can be prolonged. The aim of this study is to analyze the effect of sorafenib on the clinical outcomes in HCC patients with MVI after curative hepatectomy. Methods HCC patients who underwent hepatectomy and were pathologically diagnosed with MVI were retrospectively analyzed. Patients were divided into sorafenib group and control group. Sorafenib 400 mg, twice daily, was administered orally after surgery in the sorafenib group. The recurrence-free survival (RFS) and overall survival (OS) were observed during follow-up, and associated factors were analyzed using univariate and multivariate COX regression. Results There was no significant difference in demographics, clinical staging, and tumor index between sorafenib group (16 patients) and control group (33 matched patients). The RFS and OS were both longer in the sorafenib group, and the 3-years RFS rates of the sorafenib group and control group were 56.3% (9 of 16) and 24.2% (8 of 33), respectively (P=0.027). The 3-year OS rate of the sorafenib group was 81.3% (13 of 16), which was significantly higher than that of the control group (39.4%, P=0.006). The results of multivariate COX regression indicated that treatment with sorafenib was an independent associated factor for RFS and OS. Conclusion We believe that using sorafenib therapy after curative hepatectomy in HCC patients with MVI is effective and beneficial as it can reduce recurrence and prolong the survival time.

Abstract
BACKGROUND We aimed to identify the independent predictive factors of microvascular invasion (MVI) for curative resection of HCC and to investigate the impacts of MVI and HBeAg on long-term recurrence and survival after resection. METHODS The clinicopathological parameters of 237 patients with HCC with MVI who underwent hepatic resection from April 2005 to November 2010 were investigated. Clinical features and factors associated with the clinical outcomes of 386 patients with HCC without MVI were used for comparison. RESULTS Multivariate stepwise logistic regression analysis revealed that alpha-fetoprotein level>100μg/L, positive HBeAg, and tumour size were independent prognostic factors in patients with HCC with MVI. The overall survival (OS) of patients in the HCC with MVI group was significantly poorer compared with the HCC without MVI group (P<0.001). However, patients with HCC without MVI group exhibited a significantly better recurrence-free survival rate (RFS) (P<0.001). While the HCC with positive HBeAg group exhibited significantly lower OS compared with the HCC with negative HBeAg group (P=0.007). CONCLUSIONS AFP level>100μg/L, positive HBeAg, and tumour size>2cm are independent indicators of poorer prognosis for HCC with MVI. The present study confirmed that microvascular invasion itself had a negative impact on patient survival; moreover, HBeAg was an independent risk factor influencing OS, while not RFS of patients with HCC underwent hepatectomy. It is important to predict the presence of MVI before hepatic resection to determine treatment strategies.

Abstract
Objective This study aimed to explore the relationship between KI-67 positive cellular index and recurrence-free survival (RFS) in Barcelona Clinic Liver Cancer (BCLC) stage A and B hepatocellular carcinoma (HCC) patients, particularly those with microvascular invasion (MVI). Methods A total of 333 patients who underwent curative hepatectomy had their immunohistochemistry analyzed retrospectively for KI-67 positive cellular index. Results In total, 41.1% (137/333) of HCC patients displayed high KI-67 positive cellular index (>35%). Patients with high KI-67 positive cellular index had poorer RFS than those with low index (P<0.0001). Patients were then subdivided into an MVI positivity group (n=192) and an MVI negativity group (n=141). In the MVI positivity group, patients with high KI-67 positive cellular index had a shorter RFS after operation as compared to those with low index (P<0.0001). However, there was no significant difference in RFS between high- and low-index subgroups within the MVI negativity group (P>0.05). Additionally, patients with high KI-67 positive cellular index combined with MVI positivity had the shortest RFS of all those with MVI negativity, regardless of KI-67 cellular index level (P<0.0001). Multivariate analysis showed that node number >1, capsule absence, high KI-67 positive cellular index, and alpha-fetoprotein >400 ng/mL were independent risk factors for a recurrence of HCC with MVI. Conclusion Our results suggested that high KI-67 positive cellular index may represent a poor prognostic factor in BCLC stage A and B HCC patients, especially those with MVI.

Abstract
PURPOSE The extent of liver resection for the optimal treatment of hepatocellular carcinoma (HCC) is debated. The purpose of this study was to compare the impact of anatomic resection (AR) vs. parenchyma-sparing resection (PSR) on disease recurrence and patient survival. METHODS We retrospectively analyzed patients with HCC who underwent liver resection from January 2001 to August 2015. Patients receiving AR or PSR were compared by a propensity score analysis (PSA) (caliper = 0.1). The primary outcomes were disease-free survival (DFS) and overall survival (OS) rates, and assessed by the Kaplan-Meier method. RESULTS 455 consecutive patients were evaluated. After PSA 354 patient were studied (177 pairs for each group). The median follow-up time was 28.2 months. The median OS was 47.5 months (95% CI: 30.0-65.9) for AR and 56.5 months (95% CI 33.2-79.6) for PSR (p = 0.169). The median DFS was 29.2 months (95% CI 17.6-40.8) for AR and 24.8 months (95% CI: 15.2-34.2) for PSR (p = 0.337). The multivariate regression model showed that cirrhosis (HR 2.85, 95% CI: 1.53-5.32; p = 0.001), BCLC grade B (HR 4.15, 95% CI: 1.33-12.95; p = 0.014), microvascular invasion (HR 1.55, 95% CI: 1.03-2.31; p = 0.033), presence of satellitosis (HR 1.94, 95% CI: 1.25-3.01; p = 0.003), severe complications (HR 6.09, 95% CI: 2.26-16.40; p > 0.001) were independently associated with poor long-term oncologic outcomes. CONCLUSIONS The extent of resection did not significantly affect overall and disease-free survival while tumor characteristics and underlying liver function appeared significant determinants.

Abstract
BACKGROUND Microvascular invasion (mvi) is an important risk factor for recurrent hepatocellular carcinoma (HCC), even after curative liver resection or orthotopic liver transplantation. However, mvi is difficult to detect preoperatively. The aim of this study was to clarify the risk factors of postoperative recurrence and investigate predictive factors of mvi before hepatectomy for HCC classified within the Milan criteria. METHODS One hundred fifty-nine patients with hepatocellular carcinoma (HCC) classified within the Milan criteria, who underwent hepatectomy, were enrolled in this study. We investigated the risk factors of recurrence. In addition, we divided them into two groups: mvi-negative group and mvi-positive group, based on pathological findings after surgery. We compared the clinicopathological factors between the two groups and determined the risk factors for mvi. RESULTS Overall survival rate at 1, 3, and 5 years were 91.6%, 80.5%, and 74.9%, and the recurrence-free survival rate at 1, 3, and 5-years were 72.3%, 51.6%, and 37.2%. Risk factor analysis for tumor recurrence revealed that total bilirubin, albumin, ICGR15, AFP-L3, tumor number, mvi, and tumor stage had a significant predictive value. Multivariate analysis revealed that tumor number and mvi were significant independent risk factors for tumor recurrence. Predictive analysis for risk factors of mvi revealed that multiple tumors and AFP-L3 > 10% were significant independent risk factors for mvi in HCC classified within the Milan criteria. CONCLUSIONS The mvi was one of the independent risk factors for tumor recurrence in HCC classified within the Milan criteria. Multiple tumors and high AFP-L3 value were independent predictive factors for mvi.

Contrast-enhanced computed tomography plus gadolinium-ethoxybenzyl diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging for gross classification of hepatocellular carcinoma. Oncotarget 2017; 8:29741-29750. [PMID: 28392502 PMCID: PMC5444699 DOI: 10.18632/oncotarget.15712] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2016] [Accepted: 02/12/2017] [Indexed: 01/15/2023] Open
Abstract
Accurate gross classification through imaging is critical for determination of hepatocellular carcinoma (HCC) patient prognoses and treatment strategies. The present retrospective study evaluated the utility of contrast-enhanced computed tomography (CE-CT) combined with gadolinium-ethoxybenzyl diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging (EOB-MRI) for diagnosis and classification of HCCs prior to surgery. Ninety-four surgically resected HCC nodules were classified as simple nodular (SN), SN with extranodular growth (SN-EG), confluent multinodular (CMN), or infiltrative (IF) types. SN-EG, CMN and IF samples were grouped as non-SN. The abilities of the two imaging modalities to differentiate non-SN from SN HCCs were assessed using the EOB-MRI hepatobiliary phase and CE-CT arterial, portal, and equilibrium phases. Areas under the ROC curves for non-SN diagnoses were 0.765 (95% confidence interval [CI]: 0.666-0.846) for CE-CT, 0.877 (95% CI: 0.793-0.936) for EOB-MRI, and 0.908 (95% CI: 0.830-0.958) for CE-CT plus EOB-MRI. Sensitivities, specificities, and accuracies with respect to identification of non-SN tumors of all sizes were 71.4%, 81.6%, and 75.5% for CE-CT; 96.4%, 78.9%, and 89.3% for EOB-MRI; and 98.2%, 84.2%, and 92.5% for CE-CT plus EOB-MRI. These results show that CE-CT combined with EOB-MRI offers a more accurate imaging evaluation for HCC gross classification than either modality alone.

Abstract
OBJECTIVE We compared the efficacy of contrast-enhanced ultrasound sonography (CEUS) with sonazoid and gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced MRI for the assessment of macroscopic classification of nodular hepatocellular carcinoma (HCC). METHODS Seventy-seven consecutive patients with 79 surgically resected HCCs who underwent both preoperative CEUS and Gd-EOB-DTPA-enhanced MRI were enrolled in this retrospective study. Based on the macroscopic diagnosis of resected specimens, nodules were categorized into the simple nodular (SN) and non-SN type HCC. Two hepatologists independently assessed image datasets of the post-vascular phase of CEUS and hepatobiliary phase of Gd-EOB-DTPA-enhanced MRI to compare their diagnostic performance. RESULTS Gd-EOB-DTPA-enhanced MRI enabled the evaluation of macroscopic classification in a significantly larger number of nodules than CEUS (78/79 (98.7%) vs. 70/79 (88.6%), p < 0.05). Of 70 nodules that could be evaluated by both modalities, 41 and 29 nodules were pathologically categorized as SN and non-SN, respectively. The areas under the receiver operating characteristic curve (AUC) for non-SN did not differ between CEUS and Gd-EOB-DTPA-enhanced MRI (reader 1: 0.748 for CEUS, 0.808 for MRI; reader 2: 0.759 for CEUS, 0.787 for MRI). The AUC of combined CEUS and Gd-EOB-DTPA-enhanced MRI for SN HCC was 0.855 (reader 1) and 0.824 (reader 2), indicating higher AUC values for the combined modalities. CONCLUSIONS The diagnostic performance for macroscopic classification of nodular HCC of CEUS was comparable with that of Gd-EOB-DTPA-enhanced MRI, although some HCCs could not be evaluated by CEUS owing to lower detectability. The combination of the 2 modalities had a more accurate diagnostic performance.

Abstract
Cytokine-induced killer (CIK) cell therapy has recently been used as an adjuvant setting following resection of hepatocellular carcinoma (HCC), while its benefit remains unclear. This study aimed to evaluate the efficacy of adjuvant CIK application in solitary HCC patients undergoing curative resection with stratification of microvascular invasion (MVI).In total, specimens and data from 307 solitary HCC patients undergoing curative resection between January 2007 and December 2010 were included. Of these, 102 patients received CIK treatment after surgery (CIK group), whereas 205 patients did not (control group). Pathological evaluation was used to retrospectively determine MVI status. The CIK group had 60 MVI-negative and 42 MVI-positive patients, while the numbers in control group were 124 and 81. Kaplan-Meier and Cox regression analyses were used to validate possible effects of CIK treatment on disease free survival (DFS) and overall survival (OS) as appropriate.For all patients, the CIK group exhibited significantly higher OS than the control group (log-rank test; PDFS = 0.055, POS = 0.020). Further analysis based on MVI stratification showed that for patients with MVI, DFS and OS did not differ between the 2 groups (PDFS = 0.439, POS = 0.374). For patients without MVI, the CIK group exhibited better DFS and OS than the control group (PDFS = 0.042, POS = 0.007), and multivariate analyses demonstrated that CIK treatment was an independent prognostic factor both for DFS and OS.For solitary HCC, CIK cell therapy after curative resection improves DFS and OS for patients without MVI, but has no statistically significant survival benefit for patients with MVI.

Abstract
The purpose of this study was to clarify the diagnostic value of contrast-enhanced ultrasonography (CEUS) with perflubutane in determining the histologic grade in hepatocellular carcinoma (HCC). A total of 147 surgically resected HCCs were dichotomized as well differentiated HCC (wd-HCC) and moderately- or poorly-differentiated HCC (mp-HCC). CEUS findings were evaluated during the arterial phase (vascularity, level and shape of enhancement), portal phase (presence or absence of washout) and post-vascular phase (echo intensity and shape). Receiver operating characteristic (ROC) curve analysis for the diagnosis of mp-HCC yielded area under the ROC curve (Az) values for arterial phase vascularity and portal phase washout of 0.910 and 0.807, respectively. The Az value for the combination of vascularity and washout for the diagnosis of mp-HCC was 0.956 (95% confidence interval, 0.910-0.979), corresponding to high diagnostic value. In conclusion, CEUS can provide high-quality imaging assessment for determining the histologic grade of HCCs.

Abstract
BACKGROUNDS/AIMS Liver resection is a curative procedure performed worldwide for hepatocellular carcinoma (HCC). Deciding on the appropriate resection range for postoperative hepatic function preservation is an important surgical consideration. This study compares survival outcomes of HCC patients who underwent anatomical or non-anatomical resection, to determine which offers the best clinical survival benefit. METHODS One hundred and thirty-one patients underwent liver resection with HCC, between January 2007 and February 2015, and were divided into two groups: those who underwent anatomical liver resection (n=88) and those who underwent non-anatomical liver resection (n=43). Kaplan-Meier survival analysis and Cox regressions were used to compare the disease-free survival (DFS) and overall survival (OS) rates between the groups. RESULTS The mean follow-up periods were 27 and 40 months in the anatomical and non-anatomical groups, respectively (p=0.229). The 3- and 5-year DFS rates were 70% and 60% in the anatomical group and 62% and 48% in the non-anatomical group, respectively. The 3 and 5-year OS rates were 94% and 78% in the anatomical group, and 86% and 80% in the non-anatomical group, respectively. The anatomical group tended to show better outcomes, but the findings were not significant. However, a relative risk of OS between the anatomical and non-anatomical group was 0.234 (95% CI, 0.061-0.896; p=0.034), which is statistically significant. CONCLUSIONS Although statistical significance was not detected in survival curves, anatomical resection showed better results. In this respect, anatomical resection is more likely to perform in HCC patients with preserve liver function than non-anatomical resection.

Abstract
AIM To evaluate the oncological implications of multiplication of α-fetoprotein (AFP) and protein induced by vitamin K absence or antagonists-II (PIVKA-II) in patients with hepatocellular carcinoma (HCC). METHODS Data were prospectively collected from 516 consecutive patients who underwent a curative primary hepatectomy for HCC between 1998 and 2010. The AP-factor (AFP × PIVKA-II) was evaluated in relation to 2-year survival outcomes by receiver-operator curve analysis to determine the cut-off values. Patient survival, recurrence-free survival and risk factors were analyzed in accordance with the preoperative AP-factor. RESULTS The AP-factor was categorized into three groups depending on the serum concentrations of AFP and PIVKA-II as follows: AP1 (n = 206; AFP < 200 ng/mL and PIVKA-II < 100 mAU/mL), AP2 (n = 152; AFP × PIVKA-II < 10(5) ) and AP3 (n = 158; AFP × PIVKA-II ≥ 10(5) ). The AP-factor was found to be significantly related to pathological factors such as differentiation, portal vein invasion, hepatic vein invasion and intrahepatic metastasis. Multivariate analysis was performed to identify the risk factors for survival and recurrence. Albumin, AP-factor and pathological factors including portal vein invasion, hepatic vein invasion and intrahepatic metastasis are independent risk factors for survival. Tumor number, AP-factor, and a non-cancerous liver were determinants of recurrence. CONCLUSION The AP-factor is closely related to differentiation and microscopic vascular invasion, and was selected by multivariate analysis as an independent factor for survival and recurrence, in HCC. Patients hopeful of obtaining good outcomes after a hepatectomy could be selected by the AP-factor evaluation.

Abstract
AIM: To investigate whether neuron-glial antigen 2 (NG2) could be an effective prognostic marker in hepatocellular carcinoma (HCC).
METHODS: NG2 expression was semi-quantitatively scored from the immunohistochemistry (IHC) data based on the number of positive cells and the staining intensity. A total of 132 HCC specimens and 96 adjacent noncancerous tissue samples were analyzed by IHC for NG2 protein expression. To confirm the NG2 expression levels observed by IHC, we measured NG2 expression in 30 randomly selected tumor and adjacent noncancerous tissue samples by quantitative real-time polymerase chain reaction and Western blot. The correlations between NG2 protein expression and the clinicopathological features of HCC patients were analyzed using the χ2 test. To assess the prognostic value of NG2 for HCC, the association between NG2 expression and survival was analyzed using the Kaplan-Meier method with the log-rank test. To further evaluate the prognostic value of NG2 expression, a Cox multivariate proportional hazards regression analysis was performed with all the variables to derive risk estimates related to disease-free and overall survival and to control for confounders.
RESULTS: High NG2 expression was observed in significantly more primary tumor samples (63.6%; 84/132) compared with the adjacent noncancerous tissue samples (28.1%; 27/96) (P < 0.0001). Moreover, high NG2 protein expression was closely associated with tumor differentiation (χ2 = 9.436, P = 0.0089), recurrence (χ2 = 5.769, P = 0.0163), tumor-node-metastasis (TNM) stage (χ2 = 8.976, P = 0.0027), and invasion (χ2 = 5.476, P = 0.0193). However, no significant relationship was observed between NG2 protein expression in HCC and other parameters, such as age, sex, tumor size, serum alpha fetoprotein (AFP), tumor number, or tumor capsule. The log-rank test indicated a significant difference in the overall survival of HCC patients with high NG2 expression compared with those with low NG2 expression (29.2% vs 9.5%, P < 0.001). Moreover, NG2 expression in HCC tissue significantly correlated with disease-free survival (15.2% vs 6.7%, P < 0.001). Multivariate analysis showed that NG2 expression (HR = 2.035, P = 0.002), serum AFP (HR = 1.903, P = 0.003), TNM stage (HR = 2.039, P = 0.001), and portal vein invasion (HR = 1.938, P = 0.002) were independent prognostic indicators for OS in HCC patients. Furthermore, NG2 expression (HR = 1.974, P = 0.003), serum AFP (HR = 1.767, P = 0.008), TNM stage (HR = 2.078, P = 0.001), tumor capsule (HR = 0.652, P = 0.045), and portal vein invasion (HR = 1.941, P = 0.002) were independent prognostic indicators for DFS in HCC patients.
CONCLUSION: The up-regulation of NG2 is associated with poor prognosis in HCC. Therefore, NG2 could be useful as an additional prognostic marker to increase the resolution of traditional approaches.

Abstract
BACKGROUND The macroscopic type of hepatocellular carcinoma (HCC) is a predictor of prognosis. We clarified the diagnostic value of gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging (MRI) in the macroscopic classification of nodular hepatocellular carcinoma (HCC) as compared to angiography-assisted computed tomography (CT). METHODS A total of 71 surgically resected nodular HCCs with a maximum diameter of ≤5 cm were investigated. HCCs were evaluated preoperatively using Gd-EOB-DTPA-enhanced MRI and angiography-assisted CT. HCCs were pathologically classified as simple nodular (SN), SN with extranodular growth (SN-EG), or confluent multinodular (CMN). SN-EG and CMN were grouped as non-SN. Five readers independently reviewed the images using a five-point scale. We examined the accuracy of both imaging modalities in differentiating between SN and non-SN HCC. RESULTS Overall, the area under the receiver operating characteristic curve (A z ) for the diagnosis of non-SN did not differ between Gd-EOB-DTPA-enhanced MRI and angiography-assisted CT [0.879 (95% confidence interval (CI), 0.779-0.937) and 0.845 (95% CI, 0.723-0.919), respectively]. For HCCs >2 cm, the A z for Gd-EOB-DTPA-enhanced MRI was greater than 0.9. The sensitivity, specificity, and accuracy of Gd-EOB-DTPA-enhanced MRI for identifying non-SN were equal to or higher than values with angiography-assisted CT in all three categories (all tumors, ≤2 cm, and >2 cm), but the differences were not statistically significant. CONCLUSIONS Using Gd-EOB-DTPA-enhanced MRI to assess the macroscopic findings in nodular HCC was equal or superior to using angiography-assisted CT.

Abstract
OBJECTIVE The aim of this study was to investigate the prognostic value of tumor size alone on long-term survival and recurrence after curative resection for solitary hepatocellular carcinoma (HCC) without macroscopic vascular invasion. METHODS A single-center cohort of 615 patients with solitary HCC (a single tumor, without macroscopic vascular invasion or distant metastasis) undergoing curative hepatic resection from 2002 to 2010 was retrospectively studied. Using 2.0, 3.0, 4.0, 5.0, 8.0, and 10.0 cm as cut-off values of tumor size, the overall survival (OS) and recurrence-free survival (RFS) rates were compared between the groups of patients with tumor size up to a certain cut-off value and the groups of patients with tumor size above that cut-off value. Thus, multiple comparisons were done. The prognostic factors of OS and RFS were evaluated using univariate and multivariate analyses. RESULTS The median tumor size of all HCCs was 4.0 cm (range 0.9-22.0 cm). The in-hospital mortality rate was 1.0 %, and the overall morbidity rate was 22.3 %. The 1-, 3-, and 5-year OS rates were 96.0, 79.8, and 69.9 %, and the corresponding RFS rates were 83.6, 72.7, and 57.2 %, respectively. On univariate analyses, the 1-, 3-, and 5-year OS and RFS rates were significantly different between the individual two groups of patients as divided by the aforementioned different cut-off values of tumor sizes (all p < 0.05). However, when tumor size was put as a continuous variable into multivariate analysis, it was no longer an independent prognostic factor of OS or RFS after curative resection. CONCLUSIONS Tumor size did not independently affect long-term survival and recurrence after curative resection of solitary HCC without macroscopic vascular invasion. Therefore, there is no size limit that precludes hepatic resection for solitary HCC, provided the tumor is resectable.

Abstract
OBJECTIVE To clarify the diagnostic value of contrast-enhanced ultrasound (CEUS) with perflubutane in the macroscopic classification of small nodular hepatocellular carcinomas (HCCs). METHODS A total of 99 surgically resected nodular HCCs with a maximum diameter of 3 cm or less were analysed. HCCs were macroscopically categorized as simple nodular (SN) and non-SN. CEUS findings were evaluated during the arterial phase (vascularity, level and shape of enhancement), portal phase (presence or absence of washout) and post-vascular phase (echo intensity and shape). RESULTS Sixty-eight HCCs were categorized as SN and the remaining 31 were categorized as non-SN. For diagnosis of non-SN HCC, the areas under the receiver operating characteristic curve (A z) value for the shape of enhancement in the late arterial phase and the shape of the post-vascular image were 0.824 (95 % confidence interval [CI] 0.721-0.895) and 0.878 (95 % CI 0.788-0.933), respectively. The A z value for the combination of the shape of enhancement in the late arterial phase and the shape of the post-vascular image for the diagnosis of non-SN HCC was 0.907 (95 % CI 0.815-0.956), corresponding to a high diagnostic value. CONCLUSION CEUS can provide high-quality imaging assessment for determining the macroscopic classification of small nodular HCCs. KEY POINTS • Non-SN is one of the poor prognostic factors in patients with HCC • Assessment of macroscopic type provides valuable information for the management of HCC • CEUS can provide high-quality imaging assessment for macroscopic classification of HCC • For non-SN HCC diagnosed using CEUS, hepatectomy is preferred as curative treatment.

Abstract
OBJECTIVE Prognostic markers for hepatocellular carcinoma (HCC) could help in the clinical management and understanding of its poor prognosis. S100 calcium binding protein A4 (S100A4) is directly involved in tumour metastasis. This study evaluated S100A4 gene expression in human HCC, to identify its role in tumour progression. METHODS In this retrospective study, S100A4 protein levels in HCC samples from Chinese patients were evaluated using immunohistochemistry and compared with paired normal tumour-adjacent tissue samples (controls). All patients were evaluated for HCC recurrence. RESULTS S100A4 levels were significantly increased in HCC samples compared with controls (n = 72, each sample type). Moderately or poorly differentiated tumours had significantly higher levels of S100A4 protein than well-differentiated tumours, and those with tumour vascular invasion showed significantly higher S100A4 levels than those without invasion. Risk of recurrence increased in patients positive for S100A4, and S100A4 positivity correlated with a shorter overall survival time. CONCLUSION This pilot study suggests S100A4 as a likely tumour marker for HCC that correlates with tumour differentiation, invasion, recurrence and overall survival. S100A4 could be a useful marker of tumour aggressiveness and prognosis.

Abstract
BACKGROUND Unexpected early cancer-related death (ECRD) within 2 years due to recurrence after curative hepatectomy for solitary small (<5 cm) hepatocellular carcinoma without macroscopic vascular invasion (SSHCC) is occasionally observed. METHOD A total of 415 patients were enrolled (19 patients with ECRD and 396 patients with non-ECRD) to elucidate the risk factors of ECRD after curative hepatectomy for SSHCC. They were initially compared by limiting variables to preoperative factors to reveal predictors that could enable the modification of primary treatment. Subsequently, the same analysis was performed with all variables, including perioperative and histological factors. RESULTS In the preoperative factors, tumor size > 3 cm and elevation of tumor marker level were independent predictors of ECRD. In the analysis with all variables, excessive intraoperative blood loss, poor differentiation, and microscopic vascular invasion were predictors of ECRD. In the recurrence patterns, 79% of ECRD presented as advanced (four or more lesions) or extra-hepatic recurrence, whereas these accounted for 18% in the non-ECRD. CONCLUSION Excessive blood loss during the operation and histopathological findings of microscopic vascular invasion and poor differentiation are predictive factors of cancer-related death within 2 years of a hepatectomy for SSHCC.

Abstract
AIM We aimed to correlate the macroscopic and magnetic resonance imaging (MRI) findings of hepatocellular carcinomas (HCC). METHODS This was a multicenter study, whose study protocol was approved by each institutional review board. One hundred and forty-six resected nodules in 124 patients who had received a preoperative hepatobiliary phase of gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid-enhanced MRI (EOB-MRI) were analyzed. In both findings, we compared the diameter of HCC and macroscopic types divided into five types: (i) small nodular type with indistinct margin (SN-IM); (ii) simple nodular type (with distinct margin) (SN-DM); (iii) simple nodular type with extranodular growth (SN-EG); (iv) confluent multinodular type (CMN); and (v) infiltrative type (IF). RESULTS The diameters in each finding (Dsurg and DMRI ) were significantly correlated (R = 0.961), although Dsurg was larger than DMRI (P = 0.0216). There were significant differences between Dsurg in SN-IM and the other groups (P < 0.0001). Sensitivity, specificity and accuracy were 5.3, 99.2 and 87; 84.8, 62.7 and 81.4; 58.1, 91.3 and 84.2; 70.6, 91.5 and 89, in SN-IM, SN-DM, SN-EG and CMN, respectively. The kappa value of every size was as follows: all sizes, 0.45; 20 mm or less, 0.23; more than 20 mm, 0.56. CONCLUSION EOB-MRI could predict the macroscopic pathological findings except for SN-IM. Small tumor size might be helpful to diagnose SN-IM.

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

Abstract
PURPOSE To assess Blood Oxygen Level-Dependent (BOLD) Magnetic Resonance Imaging (MRI) for noninvasive preoperative prediction of Microvascular Invasion (MVI) in Hepatocellular Carcinoma (HCC). MATERIALS AND METHODS In this prospective, institutional review board approved study, 26 patients (21 men and 5 women age range, 34-77 years with mean age of 61 years) with HCC were evaluated preoperatively with liver MRI including baseline and post oxygen (O2) breathing BOLD MRI. Post processing of MRI data was performed to obtain R2* values (1/s) and correlated with histopathological assessment of MVI. Statistical analysis was performed to assess correlation of baseline R2*, post O2 R2* and R2* ratios to presence of MVI in HCC by binary logistic regression analysis. RESULTS MVI was present in 15/26 (58%) of HCC on histopathology. The mean R2* values ± SD at baseline and post O2 with and without MVI were 35 ± 12, 36 ± 12, 38 ± 10, 42 ± 17. The R2* values between the groups with and without MVI were not significantly different statistically. CONCLUSION BOLD MRI is unable to accurately predict MVI in HCC. The noninvasive preoperative MRI detection of MVI in HCC remains elusive.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) has a high recurrence rate after resection. Abnormal activation of the sonic hedgehog (SHH) signaling pathway contributing to the carcinogenesis of some organs had been reported. We hypothesize that activation of SHH pathway contributes to the recurrence of HCC after surgical resection. METHODS In a prospective study, from January 2006 to June 2010, a total of 50 consecutive patients with HCC after curative resection were enrolled. The ratio of the expression of messenger RNA (mRNA) of SHH, patched homolog-1 (PTCH-1) and glioma-associated oncogene-1 (GLI-1) between HCC tissues and the paired noncancerous liver tissues were measured. Both the clinicopathologic characteristics and these ratios were compared between those with recurrence and those without recurrence. They were also compared between those with and without survival. RESULTS There was a statistically significant correlation among the ratios of PTCH-1 mRNA and serum AFP level (p = 0.045), tumor size (p = 0.001), vascular permeation (p = 0.043) and tumor, node, metastasis staging system (TNM) stage (p = 0.003). A borderline significant correlation was found among ratios of GLI-1 mRNA and tumor size (p = 0.062) and TNM stage (p = 0.051). There was no such significant correlation between SHH mRNA and any parameter. Both the ratios of PTCH-1 mRNA and GLI-1 mRNA significantly adversely affected recurrence (p = 0.003 and 0.005, respectively) and survival (p < 0.001 and <0.001, respectively). CONCLUSIONS Expression of PTCH-1 mRNA and GLI-1 mRNA in HCC tissues is a potential biomarker to predict postresection disease recurrence.

Abstract
Background Liver resection for hepatocellular carcinoma (HCC) has the highest local controllability among all local treatments and results in a good survival rate. However, the recurrence rates of HCC continue to remain high even after curative hepatectomy Moreover, it has been reported that some patients with HCC have an early death due to recurrence. We analyzed the preoperative risk factors for early cancer death. Methods Between 1997 and 2009, 521 consecutive patients who underwent hepatectomy for HCC at our center were assigned to group ED (death due to HCC recurrence or progression within 1 year after hepatectomy) and group NED (alive over 1 year after hepatectomy). Risk factors for early cancer death were analyzed. Results Group ED included 48 patients, and group NED included 473 patients. The cause of death included cancer progression (150; 78.1%), operation-related (1; 0.5%), hepatic failure (15; 7.8%), and other (26; 13.5%). Between the ED and NED groups, there were significant differences in albumin levels, Child-Pugh classifications, anatomical resections, curability, tumor numbers, tumor sizes, macroscopic vascular invasion (portal vein and hepatic vein), alpha-fetoprotein (AFP) levels, AFP-L3 levels, protein induced by vitamin K absence or antagonism factor II (PIVKA-II) levels, differentiation, microscopic portal vein invasion, microscopic hepatic vein invasion, and distant metastasis by univariate analysis. Multivariate analysis identified specific risk factors, such as AFP level > 1,000 ng/ml, tumor number ≥ 4, tumor size ≥ 5 cm, poor differentiation, and portal vein invasion. With respect to the preoperative risk factors such as AFP level, tumor number, and tumor size, 3 (1.1%) of 280 patients with no risk factors, 12 (7.8%) of 153 patients with 1 risk factor, 24 (32.9%) of 73 patients with 2 factors, and 9 (60.0%) of 15 patients with 3 risk factors died within 1 year of hepatectomy (p < 0.0001). Conclusions Hepatectomy should be judiciously selected for patients with AFP level > 1,000 ng/ml, tumor number ≥ 4, and tumor size ≥ 5 cm, because patients with these preoperative risk factors tend to die within 1 year after hepatectomy; these patients might be better treated with other therapy.

Tumor-related factors do not influence the prognosis of solitary hepatocellular carcinoma after partial hepatectomy. JOURNAL OF HEPATO-BILIARY-PANCREATIC SCIENCES 2011; 18:689-99.

Abstract
BACKGROUND/PURPOSE Although many factors related to the tumor or the hepatic functional reserve may affect the outcome of partial hepatectomy for hepatocellular carcinoma (HCC), these factors have not yet been intensively investigated in patients with solitary HCC. The purpose of this study is to determine the clinicopathological factors influencing the long-term outcomes of partial hepatectomy for solitary HCC. METHODS Data on 266 consecutive patients with a solitary HCC who underwent curative hepatectomy between 1997 and 2006 were analyzed with regard to prognosis. RESULTS Overall survival rates at 3, 5, and 10 years were 89.5, 79.6, and 56.1%, respectively. The significant independent predictors for overall survival included hepatitis C virus infection, liver cirrhosis, and prolonged prothrombin activity. Disease-free survival rates at 3, 5, and 10 years were 51.7, 41.1, and 20.4%, respectively. The significant independent predictors for disease-free survival included elevated levels of aspartate amino transferase, decreased platelet counts, presence of liver cirrhosis, and prolonged prothrombin activity. Tumor-related factors such as tumor size and microscopic vascular invasion were not significant predictors of overall or disease-free survival. CONCLUSIONS The long-term outcomes of patients with a solitary HCC who underwent partial hepatectomy mainly depended on the background liver status but not on tumor-related factors; this suggests that partial hepatectomy is a remarkably effective antitumor therapy. If the hepatic functional reserve is within the permissible range, partial hepatectomy should be considered as the treatment of choice for patients with a solitary HCC.

Abstract
BACKGROUND Hepatocyte growth factor activator inhibitor type 1 (HAI-1), one of the Kunitz-type serine protease inhibitors, has an important role in cancer progression through regulation of the activity of hepatocyte growth factor. HAI-1 is expressed in hepatocellular carcinoma (HCC) to various degrees. Investigation of the relationship between HAI-1 expression and clinicopathological features of HCC may contribute to improved treatment outcomes for HCC through understanding the mechanism of tumor progression or improvement in the prediction of tumor malignancy. METHODS The study included 121 HCC patients treated surgically from 1996 to 2005. We performed immunohistological examination for HAI-1 in resected HCC specimens by use of anti-human HAI-1 monoclonal antibody. Clinicopathological features, including postoperative overall survival (OS) and disease-free survival (DFS) rates, were compared between the immunoreaction positive and negative groups. RESULTS The immunoreaction positive group included 38 patients (31%), and the negative group included 83 patients (69%). OS and DFS rates were significantly higher in the HAI-1 negative group than in the positive group. HAI-1 positivity related to multiplicity, vascular invasion, and characteristics of advanced tumor stage. In multivariate analysis, expression of HAI-1 was a significant independent prognostic tumor factor. CONCLUSIONS Expression of HAI-1 in HCC cells is associated with poor prognosis for HCC patients. HAI-1 may be important in HCC progression and may be a new prognostic factor for HCC.

Abstract
BACKGROUND AND AIM Exportin 4 (XPO4) is a recently-discovered candidate tumor-suppressor gene identified in a liver cancer mouse model. To investigate the role of XPO4 in hepatocellular carcinoma (HCC) pathogenesis, we determined XPO4 expression and its correlation to prognosis in human primary HCC. METHODS The XPO4 mRNA transcription level in HCC cell lines and tissue samples were detected by real-time quantitative polymerase chain reaction (PCR). XPO4 protein expression in 123 primary HCC clinical surgical specimens were analyzed by immunohistochemical detection. RESULTS Real-time quantitative PCR showed a decrease in XPO4 expression in HCC cell lines BEL-7402, Hep-G2, and SK-hep1 compared to the normal liver cell line LO2. Decreased XPO4 mRNA was also found in the majority of tumor tissues compared with matched non-tumor liver tissues (P = 0.004). Immunohistochemical detection revealed that XPO4 expression was reduced in 51 of 123 (41.5%) tumor resection samples compared with adjunct non-tumor tissues. We also found XPO4 expression to be significantly correlated with tumor size (P = 0.045) and histopathological classification (P = 0.004). Kaplan-Meier survival curves showed that the downregulation of XPO4 resulted in a significantly poor prognosis (P = 0.008, log-rank test), and multivariate Cox's analysis showed that XPO4 expression was an independent prognostic factor for overall survival of HCC patients (P = 0.013). CONCLUSIONS Our data suggest that XPO4 could be involved in the progression of human HCC and could serve as a potential target for gene therapy in the treatment of HCC.

Abstract
BACKGROUND Surgeons have attempted to prevent early cancer-related death after resection of hepatocellular carcinoma to identify risk factors associated with early death from hepatocellular carcinoma recurrence after liver resection. METHODS The study group comprised 350 patients who had undergone liver resection for hepatocellular carcinoma between 1997 and 2007. The preoperative risk factors for early death from intrahepatic recurrence (within 1 year after resection) were evaluated. RESULTS Fourteen (4%) patients died of intrahepatic recurrence in the first year after resection. Multivariate analyses identified the following risk factors for early cancer-related death: multiple tumors (odds ratio 10.4; 95% confidence interval, 2.42-44.3; P = .002), vascular invasion (odds ratio 10.1; 95% confidence interval 2.07-50; P = .004), serum alpha-fetoprotein level >20 ng/mL (odds ratio 9.52; 95% confidence interval 1.0--84.2; P = .043), and tumor size ≥50 mm (odds ratio 4.80; 95% confidence interval 1.06-21.9; P = .042). Each of these factors was assigned a score of 1 point, and an algorithm was developed to predict the risk of early death. Outcomes did not differ significantly between patients with 3 or 4 points (P = .48) or between those with 1 or 2 points (P = .49). Patients who underwent liver resection could be stratified into the following distinct groups according to the point score and the associated 1-year survival rate and median survival (shown respectively): 0 points, 99%, and not yet; 1 or 2 points, 96%, and 68 months; and 3 or 4 points, 50%, and 12 months) (P < .0001). CONCLUSION Even if hepatocellular carcinoma is resectable, patients with a score of 3 or 4 points may not be good candidates for liver resection.

Abstract
Abstract
Background
The gross classification of hepatocellular carcinoma (HCC) has been reported to be a significant prognostic factor for patients with HCC undergoing partial hepatectomy. The present study investigated whether the gross classification of HCC is also a prognostic factor in living donor-related liver transplantation (LDLT).
Methods
Some 119 patients undergoing LDLT for HCC were identified retrospectively from a prospective institutional database containing information on all LDLTs carried out between 1996 and 2009. Patients were divided into three groups according to the gross classification of the largest tumour in the explanted liver: type 1 HCC, single nodular type (81 patients); type 2, single nodular type with extranodular growth (21); and type 3, contiguous multinodular type (17). Clinicopathological factors and recurrence-free survival rates were compared.
Results
Recurrence-free survival rates for the whole group were 87·7 per cent at 1 year, 83·5 per cent at 3 years and 81·0 per cent at 5 years after LDLT. Type 3 HCC was associated with large tumour size, poor histological grade, a high incidence of microvascular invasion and multiple tumours. Independent predictors of poor recurrence-free survival were preoperative serum level of des-γ-carboxy prothrombin exceeding 300 mAU/ml, microvascular invasion and type 3 HCC.
Conclusion
The gross classification of HCC was an independent predictor for recurrence of HCC in patients undergoing LDLT.

Abstract
BACKGROUND AND OBJECTIVES Vascular infiltration (VI) is an important prognostic factor for hepatocellular carcinoma (HCC) and predictive parameters are necessary to preoperatively decide treatment strategies in patients with HCC. METHODS Relationships between presence and degree of VI in the portal and hepatic veins and bile duct, and post-hepatectomy survival were examined in 271 HCC patients who underwent hepatectomy. RESULTS VI was observed in 81 patients (30%). Disease-free and overall survival rates was significantly lower in patients with VI than in patients without VI, and became poorer according to the degree of infiltration (P < 0.01). Multiple, increased size, non-meeting of Milan criteria, irregular macroscopic findings and increased PIVKA-II levels were associated with degree of VI in portal vein (P < 0.01). Increased size and increased PIVKA-II level were associated with degree of VI in hepatic vein (P < 0.05). Non-meeting of Milan criteria was associated with degree of infiltration in bile duct (P = 0.034). Survival was significantly better following anatomical resection than with non-anatomical resection and, furthermore, survival was better with surgical margins >5 mm than with shorter margins in patients who underwent non-anatomical resection. CONCLUSION Adequate extent of operative procedures, but not limited resection with short margins, is useful when predictive parameters associated with VI are observed.

Abstract
Background For Hepatocellular Carcinoma (HCC) treated with hepatectomy, the extent of the resection margin remains controversial and data available on its effect on early tumor recurrence are very few and contradictory. The purpose of this study was to compare the impact of the type of resection (anatomic versus non-anatomic) on early intra-hepatic HCC recurrence in patients with solitary HCC and preserved liver function. Methods Among 53 patients with similar clinico-pathologic data who underwent curative liver resection for HCC between 2000 and 2006, 28 patients underwent anatomic resection of at least one liver segment and 25 patients underwent limited resection with a margin of at least 1 cm. Results After a close follow-up period of 24 months, no difference was detected in recurrence rates between the anatomic (35.7%) and the non-anatomic (40%) groups in either univariate (p = 0.74) and multivariate (p = 0.65) analysis. Factors contributing to early recurrence were tumor size (p = 0.012) and tumor stage including vascular invasion (p = 0.009). Conclusion The choice of the type of resection for HCC should be based on the maintenance of adequate hepatic reserve. The type of resection (anatomic vs non-anatomic) was found not to be a risk factor for early tumor recurrence.

Abstract
To clarify the characteristics of hepatocellular carcinoma (HCC) with bile duct invasion, we retrospectively analyzed clinical features and surgical outcome of HCC with bile duct invasion (b(+) group, n = 15) compared to those without bile duct invasion (b(-) group, n = 256). In the b(+) group, four patients (27%) showed obstructive jaundice, and a diagnosis of bile duct invasion was obtained preoperatively in seven patients (47%). The levels of serum bilirubin and carbohydrate antigen 19-9 were significantly higher in the b(+) group. Macroscopically, confluent multinodular type and infiltrative type were predominant in the b(+) group (P = 0.002). Microscopically, capsule infiltration (P = 0.040) and intrahepatic metastasis (P = 0.013) were predominant in the b(+) group. Portal vein invasion was associated significantly with the b(+) group (P = 0.004); however, the frequency of hepatic vein invasion was similar (P = 0.096). The median survival after resection was significantly shorter in the b(+) group than in the b(-) group (11.4 vs. 56.1 months, P = 0.002), and eight of 11 intrahepatic recurrences in the b(+) group occurred within 3 months after surgery. HCC with bile duct invasion has an infiltrative nature and a high risk of intrahepatic recurrence, resulting in poor prognosis.

Abstract
The prognosis of hepatocellular carcinoma (HCC) remains poor. Vascular invasion, tumour multiplicity and large tumour size are the conventional poor prognostic indicators related to early recurrence. However, it is difficult to predict prognosis of each HCC in the absence of these indicators. The purpose of this study is to predict early recurrence of HCC after radical resection based on whole human gene expression profiling. Microarray analyses were performed in 139 HCC primary tumours. A total of 88 cases lacking the conventional poor prognostic indicators were analysed to establish a molecular prediction system characteristic for early recurrence in 42 training cases with two polarised prognoses, and to test its predictive performance in 46 independent cases (group C). Subsequently, this system was applied to another 51 independent cases with some poor prognostic indicators (group D). The molecular prediction system accurately differentiated HCC cases into poor and good prognoses in both the independent group C (disease-free survival [DFS]: p=0.029, overall survival [OS]: p=0.0043) and independent group D (DFS: p=0.0011, OS, p=0.035). Multivariate Cox regression analysis indicated that the clinical value of molecular prediction system was an independent prognostic factor (p<0.0001, hazard ratio=3.29). Gene expression pattern related to early intrahepatic recurrence inherited in the primary HCC tumour can be useful for the prediction of prognosis.

Abstract
BACKGROUND/PURPOSE It has been reported that anatomic resection may be preferable to nonanatomic resection for small hepatocellular carcinomas (HCCs), by reducing so-called "micrometastases" (portal venous tumor extension and intrahepatic metastases). Nonanatomic resection or ablation has also been used as therapy for small HCCs. We studied the effectiveness of anatomic resection for small nodular HCCs, especially from the viewpoints of tumor size and gross classification. METHODS A retrospective cohort study was performed in 116 consecutive patients who underwent curative hepatic resection for HCCs 3 cm or smaller and with three or fewer nodules. The outcome of anatomic resection (including segmentectomy, sectoriectomy, and hemihepatectomy) was compared to that of nonanatomic partial hepatectomy. RESULTS The group that underwent anatomic resection (n = 52) had relatively better overall survival and significantly better recurrence-free survival than those with nonanatomic resection (n = 64). On Cox multivariate analysis, however, liver function was more closely associated with survival. The effect of anatomic resection was more prominent in the subgroup with the nonboundary type nodules (single nodular type with extranodular growth, confluent multinodular type, and invasive type) than in the subgroup with the boundary type (vaguely nodular and single nodular type). Micrometastases in the nonboundary type were found further from the main tumor (9.5 +/- 6.2 mm) than those in the boundary type (within 3.1 +-1.4 mm). CONCLUSIONS In patients with HCC nodules equal to or less than 3 cm and with the nonboundary type, anatomic resection should be employed to the extent that liver function allows, because this procedure would be more favorable than nonanatomic resection in eradicating micrometastases that have extended away from the tumor's margin.

Abstract
BACKGROUND Although anatomic liver resection is preferred when treating hepatocellular carcinoma (HCC), evidence that it improves survival when compared with an adequate nonanatomic resection is lacking. The purpose of this study was to compare the survival impact of anatomic versus nonanatomic resection in patients with solitary HCC. PATIENTS AND METHODS Clinicopathologic data were available for 125 patients who underwent hepatectomy for a solitary HCC confined to 1 or 2 Couinaud's segments. These patients were divided into 2 groups based on the hepatectomy procedure: anatomic (n = 83) and nonanatomic (n = 42) resection. RESULTS No differences were detected either in the hepatic recurrence rates (P = .38) or in the overall survival rates (P = .34) between the anatomic group and the nonanatomic group. The hepatectomy procedure (anatomic vs nonanatomic resection) did not affect survival in either univariate (P = 0.34) or multivariate analysis (relative risk, 1.574; P = .22). The proportion of patients who survived after recurrence was greater in the nonanatomic (15/42) than the anatomic group (13/83; P = .049), and the median survival time after recurrence was greater in patients who underwent nonanatomic resection (991 days; range, 131-4073 days) than in patients with anatomic resection (310 days; range, 48-1887 days; P = .045). CONCLUSIONS No superiority was seen in survival when HCC was treated by anatomic resection. Maintaining adequate liver function regardless of whether the resection is anatomic or not may be of greater importance.

Abstract
Hepatocellular carcinoma (HCC) frequently metastasizes to the adrenal glands. The surgical strategy for HCC associated with bilateral adrenal gland metastasis is complicated because of the possibility of both postoperative hepatic failure and adrenal insufficiency. We herein report a patient with HCC with synchronous bilateral adrenal gland metastasis that was treated successfully with a two-stage operation. A 58-year-old man with HCC (12 cm in diameter) in the right lobe of the liver and bilateral adrenal gland tumors (right, 4 cm in diameter; left, 5 cm in diameter) was admitted to our hospital. Extended right hemihepatectomy and right adrenalectomy were performed simultaneously. The postoperative course was uneventful. Three months after this operation, left adrenalectomy was performed via a retroperitoneal approach. Hydrocortisone supplement was given, and the postoperative course was again uneventful. No recurrence was observed during the 10-month follow-up period. Two-stage surgery is a safe treatment option for giant HCC with synchronous bilateral adrenal gland metastasis.

Abstract
This study was aimed at procuring directly and identifying the bacteria which had been found in paraffin-embedded liver tissues of hepatocellular carcinoma (HCC) patients. In our previous studies, Helicobacter spp. had been detected by polymerase chain reaction (PCR) and observed by histology in the liver tissues of HCC patients but had never been cultured successfully. To obtain and identify the uncultured bacteria, laser microdissection and pressure catapulting (LMPC) techniques were applied. Following microdissection from the liver tissue sections, these bacteria were examined by PCR using Helicobacter genus-specific 16S rRNA primers and sequence analysis. Amplified products of 16S rRNA were positive in all six microdissected samples with bacteria, and showed 99%-100% similarity with Helicobacter pylori by sequence analysis. Another H. pylori-specific 26 kDa gene (encoding one 26 kDa protein as H. pylori-specific antigen) was also tested by PCR. Four of six samples were positive. Therefore, Helicobacter spp. detected by PCR in the liver tissues of HCC patients in our previous studies are actually the bacteria observed by histology and identified as H. pylori by further sequence analysis. The laser-assisted microdissection technique can be extensively applied for identification of bacteria in tissue samples in bacteriology research.

Abstract
BACKGROUND Macroscopic vascular invasion is known to be a poor prognostic factor in hepatocellular carcinoma (HCC). The aim of this study was to determine the outcomes and predictive factors after hepatic resection for HCC with microvascular invasion (MVI). METHODS One hundred ten patients who underwent curative resection for HCC without macroscopic vascular invasion were included in this retrospective study. The risk factors of these patients for recurrence-free and disease-specific survival were investigated, and the clinicopathological factors predicting the presence of MVI were also determined. RESULTS Of the 110 resected specimens, 49 (45%) had evidence of MVI. By univariate analysis, MVI was found to be statistically significantly associated with greater tumor size, gross classification, histological grade, and intrahepatic micrometastasis. Gross classification proved to be the only independent predictive factor for MVI by multiple logistic regression analysis. By multivariate analysis, cirrhosis and MVI were identified as independent risk factors for recurrence-free survival. The 5-year recurrence-free survival rates for patients with and without MVI were 20.8% and 52.6%, respectively. By multivariate analysis, the number of tumors, presence of MVI, and intrahepatic micrometastasis were identified as independent predictors of disease-specific survival. The 5-year disease-specific survival rates for patients with and without MVI were 59.3% and 92.0%, respectively. CONCLUSIONS The presence of MVI was the most important risk factor affecting recurrence and survival in HCC patients after curative resection. Furthermore, this study showed that gross classification of HCC can be very helpful in predicting the presence of MVI.

Abstract
PURPOSE In this study, we tried to identify the preoperative predictors of hepatic venous trunk invasion and the prognostic factors in patients with hepatocellular carcinoma (HCC) that had come into contact with the trunk of a major hepatic vein over a distance of 1.0 cm or more. METHODS Forty patients who had such HCCs resected were entered into this study and predictors of hepatic venous trunk invasion and prognostic factors were evaluated by univariate and multivariate analyses. RESULTS AND CONCLUSIONS A combined resection of the HCC and the venous trunk was performed in 29 patients. Hepatic venous trunk invasion was observed in 12 patients, including 2 with inferior vena cava tumor thrombus. A stepwise logistic regression analysis indicated that tumors larger than or equal to 7 cm in diameter and tumors showing a poorly differentiated histological grade were independent predictors of hepatic venous trunk invasion. The survival of patients without venous trunk invasion was significantly better than that for patients with venous trunk invasion (P = 0.048). A univariate analysis revealed that Child-Pugh classification B (P = 0.002), a high des-gamma-carboxy prothrombin concentration (> or =400 mAU/ml, P = 0.023), a large HCC (> or =5.0 cm in diameter, P = 0.002), the presence of portal vein invasion (P < 0.001), the presence of venous trunk invasion (P = 0.048), the presence of intrahepatic metastasis (P < 0.001), and poorly differentiated HCC (P = 0.006) correlated with a worse overall survival after hepatic resection. In a multivariate analysis, however, only the presence of intrahepatic metastasis (P = 0.037, relative risk 8.25) was an independent predictor of poor overall survival. CONCLUSIONS Large tumors (> or =7 cm in diameter) and poorly differentiated HCCs were more likely to be associated with hepatic venous trunk invasion and intrahepatic metastasis was an independent prognostic factor in patients with HCC that had come into contact with the trunk of a major hepatic vein.

Abstract
Hepatocellular carcinoma is a highly lethal cancer that typically has poor prognosis. Prognostic markers can help in its clinical management and in understanding the biology of poor prognosis. Through an earlier gene expression study, we identified N-Myc downregulated gene 1 (NDRG1) to be significantly highly expressed in hepatocellular carcinoma compared to nontumor liver. As NDRG1 is a differentiation-related gene with putative metastasis suppressor activity, we investigated the clinical significance of its overexpression. Quantitative real-time polymerase chain reaction using an independent set of patient samples confirmed the significant overexpression of NDRG1 in hepatocellular carcinoma compared to nontumor liver samples (P<0.001). Additionally, high levels of NDRG1 transcript correlated with shorter overall survival (P<0.001), late tumor stage (P=0.001), vascular invasion (P=0.003), large tumor size (P=0.011), and high Edmondson-Steiner histological grade (P=0.005). Using immunohistochemistry, NDRG1 protein was found to be significantly overexpressed in hepatocellular carcinoma samples compared to nontumor liver or cirrhotic and benign liver lesions (P<0.001). Among the hepatocellular carcinoma samples, those which are moderately and poorly differentiated express higher levels of NDRG1 protein than those which are well-differentiated (P<0.005). Additionally, hepatocellular carcinomas with vascular invasion also express elevated levels of NDRG1 protein compared to those without vascular invasion (significant at P<0.005). Our results suggest NDRG1 to be a likely tumor marker for hepatocellular carcinoma, the overexpression of which is correlated with tumor differentiation, vascular invasion, and overall survival. Its significantly elevated expression in hepatocellular carcinoma could be a useful indicator of tumor aggressiveness and therefore patient prognosis.

Abstract
The variability in the prognosis of individuals with hepatocellular carcinoma (HCC) suggests that HCC may comprise several distinct biological phenotypes. These phenotypes may result from activation of different oncogenic pathways during tumorigenesis and/or from a different cell of origin. Here we address whether the transcriptional characteristics of HCC can provide insight into the cellular origin of the tumor. We integrated gene expression data from rat fetal hepatoblasts and adult hepatocytes with HCC from human and mouse models. Individuals with HCC who shared a gene expression pattern with fetal hepatoblasts had a poor prognosis. The gene expression program that distinguished this subtype from other types of HCC included markers of hepatic oval cells, suggesting that HCC of this subtype may arise from hepatic progenitor cells. Analyses of gene networks showed that activation of AP-1 transcription factors in this newly identified HCC subtype might have key roles in tumor development.
