Abstract
OBJECTIVE Arterially directed therapies for hepatocellular carcinoma are used for patients who are not candidates for surgery or ablation and for those who need a bridge or down-staging to liver transplantation. These therapies seem to prolong the overall survival when compared with supportive care. CONCLUSION Chemoembolization, particle embolization, drug-eluting beads, and radioembolization have been used for locoregional control. This review discusses patient selection, techniques, safety, clinical outcomes, and imaging findings related to these therapies.

Serum manganese superoxide dismutase and thioredoxin are potential prognostic markers for hepatitis C virus-related hepatocellular carcinoma. World J Gastroenterol 2011; 17:4890-8. [PMID: 22171130 PMCID: PMC3235632 DOI: 10.3748/wjg.v17.i44.4890] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/26/2011] [Revised: 08/17/2011] [Accepted: 10/14/2011] [Indexed: 02/06/2023] Open
Abstract
AIM: To evaluate the clinical significance of oxidative stress markers in patients with hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC).
METHODS: Sixty-four consecutive patients who were admitted to Kagoshima University Medical and Dental Hospital were enrolled in this retrospective study. All patients had chronic liver disease (CLD) due to infection with HCV. Thirty patients with HCV-related HCC, 34 with HCV-related CLD without HCC (non-HCC), and 20 healthy volunteers (HVs) were enrolled. Possible associations between serum manganese superoxide dismutase (MnSOD) and thioredoxin (TRX) levels and clinical parameters or patient prognosis were analyzed over a mean follow-up period of 31.7 mo.
RESULTS: The serum MnSOD levels were significantly higher in patients with HCV-related HCC than in patients without HCC (P = 0.03) or HVs (P < 0.001). Similarly, serum TRX levels were also significantly higher in patients with HCV-related HCC than in patients without HCC (P = 0.04) or HVs (P < 0.01). However, serum levels of MnSOD and TRX were not correlated in patients with HCC. Among patients with HCC, the overall survival rate (OSR) was lower in patients with MnSOD levels ≥ 110 ng/mL than in patients with levels < 110 ng/mL (P = 0.01), and the OSR tended to be lower in patients with TRX levels < 80 ng/mL (P = 0.05). In addition, patient prognosis with HCC was poorest with serum MnSOD levels ≥ 110 ng/mL and serum TRX levels < 80 ng/mL. Furthermore, a multivariate analysis using a Cox proportional hazard model and serum levels of five factors (MnSOD, prothrombin time, serum albumin, serum α-fetoprotein (AFP), and serum des-γ-carboxy prothrombin) revealed that MnSOD levels ≥ 110 ng/mL (risk ratio: 4.12, 95% confidential interval: 1.22-13.88, P = 0.02) and AFP levels ≥ 40 ng/mL (risk ratio: 6.75; 95% confidential interval: 1.70-26.85, P < 0.01) were independent risk factors associated with a poor patient prognosis.
CONCLUSION: Serum MnSOD and TRX levels are potential clinical biomarkers that predict patient prognosis in HCV-related HCC.

Abstract
Locoregional therapy (LRT) is used as a bridge to orthotopic liver transplant (OLT) for hepatocellular carcinoma (HCC) patients. Liver explants in OLT patients with HCC were studied regarding both tumor stage, histology, and immunohistochemical staining for cytokeratin (CK)7, CK19, P53, Ki-67, and vascular endothelial growth factor (VEGF). Patients receiving no LRT (control) (n=30) were compared with LRT treatment groups with conventional transarterial chemoembolization (cTACE) (n=25) or drug-eluting bead transarterial chemoembolization (DEB TACE) (n=17). Tumor stage and histology were similar between treatment and control groups. The mean percent necrosis was significantly higher for treatment groups versus the control group (p<0.0001 for both groups versus control) and was significantly higher in the cTACE group versus the DEB TACE group. Only the DEB TACE group showed peritumoral CK19 positivity, and tumors were all CK19-negative. Using a threshold of 50% of tumoral cells, tumoral VEGF was significantly different between groups, with the control group having the highest degree of positivity; however, peritumoral VEGF was not significantly different between the groups. The Ki-67 proliferation fraction was higher in the treated groups with a statistically significant difference between the DEB-treated group and those without treatment (p=0.02). There were no statistically significant differences in tumoral or peritumoral CK7 or p53. Percent necrosis and percent Ki-67 positivity were higher with LRT, with a significant difference between groups for percent necrosis, confirming that LRT causes necrosis and suggesting that treatment leads to increased proliferation and decreased tumoral VEGF.

Abstract
Background/Aims The Barcelona Clinic Liver Cancer (BCLC) staging system is logical for the staging and treatment of hepatocellular carcinoma (HCC) because it was based on survival data. This study evaluated the applicability of the BCLC staging system and reasons for divergence from BCLC-recommended treatments in Korean HCC patients. Methods One hundred and sixty consecutive HCC patients were prospectively enrolled. Treatments were generally recommended according to the guideline of the American Association for the Study of Liver Diseases, but patients were also informed about alternative treatments. The final decision was made with patient agreement, and was based on the doctor's preferences when a patient was unable to reach a decision. Results There were 2 (1%), 101 (64%), 20 (12.5%), 34 (21.5%), and 3 (1%) patients with very early-, early-, intermediate-, advanced-, and terminal-stage disease, respectively. Only 64 patients (40%) were treated according to BCLC recommendations. The treatment deviated from BCLC recommendations in 68% (69/101) and 79% (27/34) of patients with early and advanced stage, respectively. The main causes of deviation were refusal to undergo surgery, the presence of an indeterminate malignancy nodule, the absence of a suitable donor, or financial problems. Conclusions Donor shortage, financial problems, the relatively limited efficacy of molecular targeting agents, and the presence of an indeterminate nodule were the main causes of deviation from BCLC recommendations. Even after excluding cases in which decisions were made by patient preference, only 66% of the HCC patients were treated according to BCLC recommendations. Treatment guidelines that reflect the Korean situation are mandatory for HCC patients.

Abstract
BACKGROUND & AIMS Hepatocellular carcinoma (HCC) can result from hepatitis C virus (HCV)-related liver disease and is the fastest-growing cause of cancer-related death in the United States. α-fetoprotein (AFP) has been used as a prognostic factor for HCC, but the value of AFP as a prognostic factor for HCV-related HCC in the United States is unknown. We investigated whether higher levels of AFP at the time of diagnosis are associated with increased mortality of patients with HCV-related HCC. METHODS In a retrospective study, we collected data from a cohort of HCV-infected veterans, identifying incident HCC cases from October 1, 1998, to January 1, 2007 (n = 1480 patients). The mean serum levels of AFP, obtained within 60 days before to 30 days after HCC diagnosis, were determined for 1064 patients and categorized as less than 10 ng/mL (18%), 10 to less than 100 ng/mL (30%), 100 to less than 1000 ng/mL (22%), or 1000 ng/mL or more (29%). Cox proportional hazard models were used to associate serum levels of AFP with mortality, adjusting for demographic features, clinical factors, and treatment. RESULTS The median survival times were significantly lower among patients with higher levels of AFP: 709 days for patients with less than 10 ng/mL, 422 days for patients with 10 to less than 100 ng/mL, 208 days for patients with 100 to less than 1000 ng/mL, and 68 days for patients with 1000 ng/mL or more. In the multivariate analysis, increased levels of AFP (10 to <100, 100 to <1000, and ≥1000) were associated significantly with increased mortality, compared with a serum AFP level of less than 10; hazard ratios were 1.50, 2.23, and 4.35, respectively. CONCLUSIONS Serum AFP level at the time of diagnosis with HCV-related HCC is an independent predictor of mortality.

Abstract
PURPOSE To assess the survival time of patients with HCC following transarterial chemoembolization performed in a highly selective and sequential way. PATIENTS AND METHODS 124 HCC patients (102 male, 22 female; mean age 63±11 years) treated with selective and sequential chemoembolization at a single center were included. Selective chemoembolization was performed through a coaxially introduced microcatheter in a segmental or subsegmental hepatic artery. Treatment was stopped after complete stasis of the blood flow in the tumor-feeding vessel. The primary endpoint of the study was overall survival. RESULTS The median overall survival of the entire patient population was 27.2 months (mo) (±8.9 mo, 95% CI 9.8 mo, 44.6 mo). When stratified according to liver function the median survival was 46.1 mo (±9.0 mo; 95% CI 28.5 mo, 63.7 mo) for Child-Pugh A and 11.1 mo (±4.3 mo; 95% CI 2.7 mo, 19.5 mo) for Child-Pugh B (p<.001). The median survival was 46.1 mo (±16.6 mo; 95% CI 13.5 mo, 78.7 mo) for BCLC stage A, 19.7 mo (±2.6 mo; 95% CI 14.6 mo, 24.8 mo) for BCLC stage B, and 14.4 mo (±5.0 mo; 95% CI 4.5 mo, 24.3 mo) for BCLC stage C (p<.01). CONCLUSION Selective and sequential chemoembolization offers long survival times in patients with HCC. Those patients with preserved liver function benefit more than patients with limited liver reserve.

Abstract
BACKGROUND Treatment for patients with intermediate-stage hepatocellular carcinoma (HCC) is controversial. This study compared the long-term survival of patients beyond the Milan criteria who received surgical resection (SR) or transarterial chemoembolization (TACE). METHODS A total of 268 and 455 HCC patients beyond the Milan criteria undergoing SR and TACE, respectively, were retrospectively evaluated. After propensity score analysis to adjust for baseline differences, 146 pairs of matched patients were selected from each treatment arm. Long-term survival was compared by the Kaplan-Meier method. Independent prognostic predictors were determined by the Cox proportional hazards model. RESULTS Long-term survival was significantly better for the SR group by univariate survival analysis (P < .001). In the Cox model, SR was identified as an independent predictor of better prognosis (hazard ratio = 0.3, 95% confidence interval [95% CI]: 0.23-0.4; P < .001). Despite similar baseline characteristics in the propensity score model, patients who underwent SR had significantly better survival than patients who underwent TACE (P < .001). Patients receiving TACE had 2.56-fold increased risk of long-term mortality in the propensity model (95% CI: 1.73-3.78). The SR and TACE groups had comparable 30- and 90-day posttreatment mortality. The Cox model consistently disclosed the significant superiority of SR in terms of long-term survival in the propensity score model (P < .001). CONCLUSIONS For HCC patients beyond the Milan criteria, SR is considered equally safe as TACE and provides better long-term survival. SR may be regarded as the priority treatment for these patients.

Abstract
OBJECTIVE To evaluate the influence of body mass index (BMI) on postoperative death in patients undergoing surgery for HCC. METHODS Three hundred forty-two patients were enrolled, and divided into three groups: Group A, BMI <22.5; Group B, BMI ≥22.5 to <25; Group C, BMI ≥25. Univariate and multivariate analyses of postoperative death were performed to compare BMI with clinical factors. Kaplan-Meier analysis and log rank test were used to compare such outcome in Groups A, B, and C. RESULTS Kaplan-Meier analysis and log rank test revealed that Group A had a higher rate of postoperative death than Group B or C (P = 0.010). Univariate and multivariate analyses selected being underweight (Group B, C/Group A) (odds ratio, 1.829; 95% C.I., 1.091-3.068; P = 0.022) as one of the factors predictive of postoperative death, together with aspartate aminotransferase level (P = 0.042) and HCC growth pattern (P = 0.032). CONCLUSIONS BMI is a simple but important predictor of postoperative death in patients undergoing surgery for HCC, and is able to classify such patients into three independent groups.

Abstract
We performed a retrospective review of 281 hepatocellular carcinoma (HCC) patients with portal vein tumor thrombosis (PVTT) treated with radiation therapy (RT) between 1998 and 2008 to develop a prognostic model for those patients. Of the 281 patients, PVTT and intrahepatic main masses completely disappeared in 10 patients (3.6%), and shown a partial response in 141 patients (50.2%). The median survival was 11.6 months. Patients who had more than PR have shown significantly longer survival than the others (22.0 months vs 5.0 months, P < 0.001). On the multivariate analysis, pre-treatment poor prognosticators for overall survival were ECOG performance status, Child-Pugh class, multiple tumors, main PVTT, complete portal vein occlusion, lymph node metastasis, and primary tumor size. Prognostic index of RT for PVTT of HCC (PITH) scores were defined as the number of pre-treatment poor prognostic factors. PITH scores correlated well with overall survival. In the analysis of 1 and 2 yr overall survival rate, patients who had PITH scores of 3 or greater showed a significantly lower rate of overall survival than the others (33.0%, 17.3% vs 70.1%, 40.8%, respectively, P < 0.001). The PITH scoring model, proposed in the current study in HCC patients with PVTT, reliably predict overall survival.

Abstract
OBJECTIVE Improving the prognostic stratification of unresectable hepatocellular carcinoma (HCC) patients is critically needed. Since patients' survival is closely linked to the severity of the underlying liver disease, and insulin-like growth factor-1 (IGF-1) is produced predominantly in the liver, we hypothesized that IGF-1 may correlate with patients' survival and hence improve the prognostic ability of the Cancer of the Liver Italian Program (CLIP) score. METHODS Baseline plasma IGF-1 and clinicopathologic parameters were available from 288 patients. Multivariate Cox regression models, Kaplan-Meier curves, and the log-rank test were applied. Recursive partitioning was used to determine the optimal cut point for IGF-1 using training/validation samples. Prognostic ability of the I-CLIP (I = IGF) was compared to CLIP using C-index. RESULTS IGF-1 significantly correlated with the clinicopathologic features. With an optimal IGF-1 cut point of 26 ng/ml, the overall survival of patients with IGF-1 >26 was 17.7 months (95% CI 13.6-22.8), and with IGF-1 ≤26 was 5.8 months (95% CI 4.0-12.5), p < 0.0001. The concordance probabilities for CLIP and I-CLIP were 0.7037 and 0.7096, respectively (p < 0.0001). CONCLUSIONS Our preliminary results indicate that I-CLIP significantly improved prognostic stratification of patients with advanced HCC. However, independent validation of our study is warranted.

Abstract
The incidence of hepatocellular carcinoma (HCC) is increasing worldwide. A multi-disciplinary approach is required for its management. Screening high-risk patients allows for earlier diagnosis and the use of potentially curative therapies. Current recommendations for HCC screening for patients with cirrhosis are an abdominal ultrasound and serum alpha fetoprotein level every 6 to 12 months. Treatment choice depends on tumor stage, liver function and the patient's overall functional status. Curative therapies include surgical resection, liver transplantation (LT), transarterial chemoembolization, and radiofrequency ablation (RFA). Surgical resection, either primary resection or LT, is the treatment most likely to result in cure of HCC. Which option to pursue is based on multiple factors. LT has the potential benefit of treating both HCC and the underlying cirrhosis; however, long wait times incur the risk of tumor progression. Firm recommendations regarding the role of living donor LT for HCC are not yet possible because of conflicting data. HCC recurrence after LT is 8-11% and several adjuvant therapies have been investigated to reduce this. Bridging therapy and tumor downsizing are techniques that also may be considered to deal with long waiting periods and qualification for LT, respectively. If neither LT nor primary resection is possible, loco-regional therapies such as RFA and TACE should be considered. Systemic chemotherapies have proved disappointing for the treatment of HCC; however, newer targeted therapies such as sorafenib and cetuximab have provided new hope for the future.

Abstract
Many staging systems of hepatocellular carcinoma (HCC) were established; however, there is no consensus on which is proper in predicting prognosis. This study aims to evaluate various commonly used staging systems of HCC. Patients who underwent surgery during 2001-2007 were included. All patient data were retrospectively staged using six staging systems, that are American Joint Committee on Cancer (AJCC) Tumour-Node-Metastasis (TNM), Okuda staging, Cancer of the Liver Italian Program (CLIP), Barcelona Clinic Liver Cancer (BCLC), Chinese University Prognostic Index (CUPI), and Japan Integrated Staging (JIS). Child-Pugh classification was also evaluated. The staging systems were compared by mean of overall and disease-free survival. Total of 99 patient data were enrolled in the analyses. All staging systems except Okuda were significant in determining overall survival in univariate analyses. In multivariate analyses, TNM and Child-Pugh demonstrated better predictive power for overall survival. In terms of disease-free survival, univariate analyses revealed that TNM, CLIP, BCLC, CUPI, and JIS were significant, and TNM was the best predictive staging system in multivariate analyses. In our study, TNM and Child-Pugh are the representative systems in predicting survival of HCC patients who undergo surgical resection. Moreover, they are practical and easily assessable in clinical practice.

Abstract
Active screening of patients at risk for HCC has led to the identification of early HCCs that are amenable to treatment with a high rate of cure. This requires high-quality ultrasound examinations at 6-month intervals. If widely applied, screening has the potential to substantially reduce the mortality from this disease. The application of the Barcelona Cancer of the Liver Clinic (BCLC) staging system should standardize assessment of prognosis and determination of the most effective treatments for each stage. With new molecular targeted agents coming, it is critical that studies are performed in patients stratified by stage into homogeneous groups. Because it is linked with therapy, the BCLC is ideally suited to this purpose.

Abstract
BACKGROUND AND AIM The widespread use of screening programs has resulted in an increase in detection of small hepatocellular carcinoma (HCC). Surgical resection generally leads to favorable outcomes in this group of patients; however, the prognostic significance of tumor size and the optimal cutoff point in resected specimens of small HCC have not been well defined. The aim of current study is to evaluate the prognostic significance of tumor size in small resected HCC. METHODS Patients who underwent surgical resection for small HCC at the Changhua Christian Hospital during January 2001 to June 2007 were enrolled. Small HCC was defined as a single HCC nodule with maximum diameter ≤ 5 cm. Cox regression hazard ratios for cancer-specific death were calculated to survey the prognostic significance of tumor size. We then determined the optimal cut-point for tumor size that could be used to stratify patients into 5-year disease-free survival (DFS) and cancer-specific survival (CSS) groups. RESULTS A total of 140 patients who underwent resection of small HCC were enrolled. The mean tumor size was 2.9 cm (range 0.9-5.0) and the mean follow-up period was 43.4 months. The 5-year DFS and CSS rates were 46.6% and 81.6%, respectively. Cox regression analysis revealed that tumor size (hazard ratio = 2.973, 95% confidence interval: 1.073-8.239, P = 0.036) was an independent prognostic factor. Our analysis showed that a tumor size of 3 cm was the cut-point that could dichotomize patients into statistically different 5-year DFS and CSS risk groups. CONCLUSIONS Tumor size is an independent prognostic factor in resected small HCC and the prognostic significance of tumor size may vary according to different cut-off points.

Abstract
Radiofrequency ablation (RFA) and transarterial chemoembolization (TACE) are used to treat hepatocellular carcinoma (HCC). This study was designed to compare the long-term survival of HCC patients within the Milan criteria who underwent RFA or TACE. In all, 315 RFA patients and 215 TACE patients with HCC within the Milan criteria were analyzed. Propensity scores were generated to select matched patients. For the propensity model, 101 patients were selected from each arm of the study. Independent prognostic predictors were determined with the Cox proportional hazards model. The long-term survival was significantly better for the RFA group in the univariate survival analysis (P = 0.048). In the Cox model, the following were identified as independent predictors of poor prognosis (TACE was not): age > 69 years (P = 0.026), serum α-fetoprotein level > 20 ng/mL (P = 0.003), ascites (P < 0.001), Eastern Cooperative Oncology Group performance status ≥ 1 (P = 0.004), total tumor volume (TTV) > 8.2 cm³ (P = 0.020), and vascular invasion (P = 0.023). With similar baseline patient characteristics generated in the propensity score model, there was no significant difference in the long-term survival rates of the 2 groups of patients. A subgroup analysis showed that among patients with a TTV < 11 cm³, the RFA group had significantly better long-term survival than the TACE group (P = 0.032). In conclusion, TACE and RFA lead to comparable long-term survival rates for HCC patients within the Milan criteria. Patients with a smaller TTV (<11 cm³) are likely to benefit more from RFA treatment. Further studies are needed to compare RFA and TACE in patients with early-stage cancers.

Abstract
Staging of hepatocellular carcinoma (HCC) represents a controversial and complex topic, since prognosis is largely dependent on several variables other than tumor extension, such liver function and general clinical conditions. Up to now, there is no agreement regarding the most reliable clinical staging system for HCC. Ideally, the staging system should be simple and easily obtainable and should not be influenced by differences in patient populations. So far, in Western countries, the Barcelona Clinic for Liver Cancer (BCLC) staging system represents the most frequently adopted classification. It is simple and guides the clinicians through the therapeutic decision process. Magnetic resonance imaging represents the most proper imaging modality for correct staging of HCC, providing high accuracy in evaluating tumor extension as well as tumor response to treatment (after percutaneous ablation, transarterial chemoembolization, or molecular-targeted therapy). The present review describes the most frequently used staging systems and the treatment options that are recommended for the different stages of the disease.

Abstract
BACKGROUND Extrahepatic metastases represent a major obstacle for further improving prognosis of hepatocellular carcinoma. AIM To assess clinical predictors of extrahepatic metastases in a large cohort followed in a single centre. METHODS We evaluated clinical files of 520 consecutive patients with hepatocellular carcinoma admitted from 1994 to 2002 to our Liver Unit. The following risk factors were assessed: age, gender, hepatitis viruses, alcohol, diabetes, size, number and differentiation of hepatocellular carcinoma, percutaneous biopsy, portal thrombosis, alpha-fetoprotein, Child-Pugh, Cancer Liver Italian Program and Model for End-stage Liver Disease scores, Barcelona Clinic Liver Cancer classification, varices, hepatocellular carcinoma treatment. RESULTS Extrahepatic metastases were detected in 55/520 patients (10.5%) after 0-72 months (median 15, CI 3-20) from initial evaluation. Lower bilirubin, INR, Child-Pugh and Model for End-stage Liver Disease scores, higher alpha-feto protein levels, portal thrombosis and absence of oesophageal varices were all associated with distant metastases at univariate analysis. Absence of oesophageal varices and portal thrombosis resulted as independent predictors (P = 0.0003 and P = 0.004, respectively) on multivariate logistic regression. Patients with metastases showed poorer survival (3 months) than total hepatocellular carcinoma population (26 months). CONCLUSIONS Extrahepatic metastases of hepatocellular carcinoma are rare but significantly impair prognosis. Extrahepatic metastases were more frequent in patients with well preserved liver function. Absence of oesophageal varices and presence of portal thrombosis were the strongest risk factors.

Abstract
Hepatocellular carcinoma (HCC) is a heterogeneous condition, with multiple confounding factors making patient assessment extremely complex. Tumor burden, the presence of symptoms, liver function, and comorbidities must all be considered to ensure accurate patient assessment, thereby providing physicians with a common language on which to base treatment decisions and guide research. Although many staging classifications have been developed, there is no consensus on the best classification to use. The Barcelona Clinic Liver Cancer system is a promising candidate for a standard western classification, because it has been externally validated and is endorsed by the European Association for the Study of the Liver and the American Association for the Study of Liver Diseases. Similarly, the biomarker-combined Japanese Integrated Staging (JIS) score is the most promising candidate for a standard Asia-Pacific classification, because it has been externally validated and shown to be superior to conventional JIS. Because risk factors vary significantly by region, so too does the predictive power of current staging classifications; any standard global staging classification would need to be validated in both western and Asia-Pacific patients. To date, no such globally validated classification exists. Findings from scientific research have improved our understanding of HCC and enabled us to refine current classifications. The role of tumor markers to predict survival was recently reported, and α-fetoprotein, lens culinaris agglutinin-reactive α-fetoprotein, and des-γ-carboxyprothrombin have now been incorporated into some classifications. Molecular markers have also been linked with poor outcomes and will likely play a role in future classifications. Although more work is required, it is hoped that these and other ongoing research efforts will eventually enable the development of a global staging classification.

Abstract
Hepatocellular carcinoma (HCC) is a major world health problem because of the high incidence and case fatality rate. In most patients, the diagnosis of HCC is made at an advanced stage, which limits the application of curative treatments. Most HCCs develop in patients with underlying chronic liver disease. Chronic viral hepatitis B and C are the major causes of liver cirrhosis and HCC. Recent improvements in treatment of viral hepatitis and in methods for surveillance and therapy for HCC have contributed to better survival of patients with HCC. This article reviews the epidemiology, cause, prevention, clinical manifestations, surveillance, diagnosis, and treatment approach for HCC.

Abstract
Recently, a link between high levels of circulating IL-6 and hepatocellular carcinoma (HCC) has been proposed. In addition, single nucleotide polymorphisms (SNPs) in the promoter region of the IL-6 gene have been reported to be related to several inflammatory-related conditions, including cancer. The purpose of this article is: (1) to evaluate the frequencies of SNPs in the IL-6 promoter region at position -174 and IL-6 serum levels in a group of patients with HCC and underlying liver cirrhosis (LC), and compare them with a group of LC patients without HCC; (2) to determine whether a possible correlation exists between the allelic variations, IL-6 serum levels, and the risk of developing HCC. The study included 105 HCC and 95 LC patients. Genomic DNA was isolated using commercially available kits. DNA samples were typed for relevant SNPs of the IL-6 promoter region (-174 G>C, G allele being associated with higher levels of the cytokine). The Restriction Fragment Length Polymorphism (RFLP-PCR) method was used to type the SNPs. IL-6 serum levels were determined using an ultrasensitive commercially available ELISA kit. IL-6 serum levels were higher in G/G compared to C/C genotypes only in HCC (z=2; p=0.04) and G/G versus G/C (z=1.8; p<0.03). IL-6 serum levels in G carriers (G/G+G/C) were higher in HCC 4.8 (0.2-17.5) versus LC patients 2.2 (0.07-11.5) (z=2.8; p=0.004). There was no difference for genotype C/C. IL-6 serum levels in HCC correlated with G carriers (G/G+G/C) (ρ=0.25, p=0.05). A positive correlation was also found between sIL-6 levels and some parameters of liver function both in LC and in HCC patients.

Abstract
BACKGROUND AND AIM Hepatitis B viral (HBV) infection is the predominant etiology of hepatocellular carcinoma (HCC) in Asia. Our group previously reported a staging system known as the Chinese University Prognostic Index (CUPI) for HCC populations of which HBV infection is the predominant etiology. This study aims to validate CUPI and compare with other published staging systems. METHODS We analyzed a prospective cohort of patients with newly diagnosed HCC from 2003 to 2005. All patients were staged with CUPI, Barcelona Clinic Liver Cancer Classification (BCLC), Cancer of the Liver Italian Program score (CLIP), tumor-node-metastasis (TNM) and Okuda systems at diagnosis. They were followed with survival data and the performance of each staging system (in terms of homogeneity, discriminatory ability and monotonicity of gradient) were analyzed and compared. RESULTS A total of 595 patients (80.2% with chronic HBV infection) were analyzed. The median follow-up was 41.4 months and the median survival was 6.6 months. Multivariate analyses identified symptomatic disease, ascites, vascular involvement, Child-Pugh-stage, alpha-fetoprotein and treatment to be the independent prognostic factors. CUPI could identify three groups with statistically significant survival difference (P < 0.0001). Both CUPI and CLIP had the most favorable performance in terms of discriminatory ability, homogeneity and monotonicity. CUPI performed the best in predicting 3-month survival while CLIP performed better in predicting the outcome of 6- and 12-month survival rate. BCLC was inferior to CLIP and CUPI in the overall performance. CONCLUSION We have validated CUPI in a population composed of predominant HBV-related HCC. CUPI is an appropriate staging system for HBV-related HCC. In patients with advanced HCC, both CUPI and CLIP offer good risk stratification.

Abstract
OBJECTIVE To assess and compare the predictive values of the hepatic Glasgow Prognostic Score (hGPS) and Cancer of the Liver Italian Program (CLIP) score in patients undergoing surgery for primary hepatocellular carcinoma (HCC). METHODS The hGPS was calculated as follows: patients with an elevated level of C-reactive protein (CRP) (>0.3 mg/dl) were allocated a hGPS of 1 or 2 depending on the absence or presence of hypoalbuminemia (<3.5 g/dl), and patients without an elevation of the CRP level (≤ 0.3 mg/dl) were allocated a hGPS of 0. RESULTS Three hundred patients were evaluated. The hGPS divided patients into three independent groups, and that a hGPS of 2 predicted a higher mortality rate (P < 0.001) than a hGPS of 0 or 1. Univariate analysis demonstrated that hGPS (0, 1/2) (P = 0.010) was one of the factors predictive of postoperative mortality, along with the CLIP score (0, 1/≥ 2) (P = 0.021). Comparative analysis using these two factors showed that the hGPS was predictively superior to the CLIP score (P = 0.033). CONCLUSIONS The hGPS is able to divide patients undergoing surgery for primary HCC into three independent groups, and is considered to be an important factor predictive of postoperative mortality in such patients.

Abstract
Recent technological advances allow precise and safe radiation delivery in hepatocellular carcinoma. Stereotactic body radiotherapy is a conformal external beam radiation technique that uses a small number of relatively large fractions to deliver potent doses of radiation therapy to extracranial sites. It requires stringent breathing motion control and image guidance. Selective internal radiotherapy or radioembolization refers to the injection of radioisotopes, usually delivered to liver tumors via the hepatic artery. Clinical results for both treatments show that excellent local control is possible with acceptable toxicity. Most appropriate patient populations and when which type of radiation therapy should be best employed in the vast therapeutic armamentarium of hepatocellular carcinoma are still to be clarified.

Abstract
PURPOSE Recommendations of the Barcelona Clinic Liver Cancer (BCLC) therapeutic flow-chart, endorsed by the American Association for the Study of Liver Diseases (AASLD), are the most applied worldwide. Over recent years, however, several referral centers have questioned some of the BCLC treatment allocations and proposed alternative strategies. The present study plans to review and discuss these suggestions, with the aim to evaluate whether there are well-grounded reasons to reconsider some of the BCLC/AASLD recommendations. METHODS A search was made into the MEDLINE database, focusing on randomized controlled trials, meta-analysis reviews, case-control studies, concordant clinical trials on novel therapies and studies reporting the opinion of respected experts. Their results and conclusions were compared stage by stage with BCLC/AASLD recommendations. RESULTS In stage 0 (very early, or single <2 cm, or carcinoma in situ, Child A) radiofrequency should replace resection. In stage A (early, or single or three nodules up to 3 cm, Child A-B) radiofrequency and resection should expand their indications. In stage B (intermediate, or multinodular, Child A-B) resection and transplantation should expand their indications, while intra-arterial therapies are changing from conventional to selective treatments. In stage C (advanced, portal invasion or extrahepatic disease, Child A-B) systemic therapies should offer previously unknown promising options. CONCLUSION In our opinion, so much evidence leads to suggest it is time to reconsider several BCLC/AASLD recommendations. Some treatments are comparable in results but vary in costs, local availability, or complication rates.

Abstract
BACKGROUND & AIMS There are few data available about the prevalence or effects of cirrhosis in patients with hepatocellular carcinoma (HCC) from viral hepatitis. We compared patients with HCC and hepatitis B virus (HBV) or hepatitis C virus (HCV) infections to determine the proportions of cirrhosis in each group, virologic and tumor characteristics, and overall survival. METHODS This analysis included patients with HBV (n = 64) or HCV (n = 118) infection who were diagnosed with HCC at the Mayo Clinic in Rochester, Minnesota from 1994-2008; groups were matched for age and sex. The diagnosis of cirrhosis was based on histology and, if histologic information was insufficient or unavailable, clinical indicators that included ascites or varices, thrombocytopenia or splenomegaly, and radiographic configuration of cirrhosis. Virologic characteristics, tumor stage, and patient survival were also assessed. RESULTS The prevalence of histologic cirrhosis was 88% among patients with HBV infection and 93% among those with HCV infection (P = .46). When the most inclusive criteria for cirrhosis were applied, cirrhosis was present in 94% of patients with HBV and 97% with HCV (P = .24). Among HCV patients, 5.2% were negative for HCV RNA after antiviral treatment; 63.4% of HBV patients had HBV DNA <2000 IU/mL with or without treatment. Patients with HBV tended to have less surveillance and more advanced stages of HCC, without differences in survival from those with HCV infection (P = .75). CONCLUSIONS Most patients with HCC and chronic viral hepatitis had evidence of cirrhosis, including those with HBV infection and those without active viral replication.

Abstract
BACKGROUND & AIMS Patients with hepatocellular carcinoma (HCC) in a palliative setting have a poor prognosis despite recent therapeutic progress. Several prognostic scores, such as the BCLC and the CLIP, have been shown to be useful in helping select treatment options ranging from transplantation to palliative care. However, the discriminatory ability of these scores is inadequate in palliative settings, which concern about 70% of HCC patients. In this paper, we propose and validate a new prognostic score for patients in the palliative setting. METHODS The prognostic score was developed on a set of 416 patients from a negative randomized clinical trial conducted by the Fédération Francophone de Cancers Digestifs. It was then subsequently validated on a second set of 271 patients from another negative trial. Backward selection was used to identify independent baseline characteristics. Measures of discrimination and predictive values were computed to assess the quality of the developed score. Comparisons with the BCLC and the CLIP - with and without the WHO performance status (PS) score - were performed. RESULTS Tumour morphology, portal vein obstruction, metastasis, ascites, jaundice, alpha-foetoprotein, and serum alkaline phosphatase were included in the final score. From the training dataset, three groups of increasing risk were defined, and these were associated with hazard ratios (HR) of 2.13 and HR = 5.72. Similar results were obtained on the validation dataset. This score provides a better discriminatory ability than BCLC and CLIP in this setting. Unfortunately, absolute performances for these scores remain poor. CONCLUSIONS The new prognostic score and CLIP + PS are recommended in palliative settings. However, new prognostic variables are necessary.

Abstract
PURPOSE Systemic chemotherapy is the only option for patients with unresectable/metastatic hepatocellular carcinoma (HCC) who are not candidates for local/regional treatment. However, the response to such treatment and survival are poor, especially in hepatitis B virus (HBV) endemic areas. The aim of this study was to determine the efficacy of cisplatin-based combination chemotherapy and identify a subgroup of advanced HCC patients with favorable responses. MATERIALS AND METHODS The medical records of all consecutive patients with unresectable/metastatic HCC who received cisplatin-based combination chemotherapy between January 2003 and October 2009 were reviewed. Time to progression (TTP) and overall survival (OS) were determined using Kaplan-Meier analysis. Univariate and multivariate analyses were performed to identify prognostic factors for TTP and OS. RESULTS Data for 46 patients were analyzed. First-line chemotherapies consisted of cisplatin-based combination treatment with doxorubicin, fluoropyrimidines and gemcitabine. The response rate for all patients was 4.3%. The median TTP and OS were 1.8 (95%confidence interval [CI], 1.1 to 2.5) and 7.2 (95% CI, 3.0 to 11.5) months, respectively. Eastern Cooperative Oncology Group (ECOG) performance status (PS), Child classification, Cancer of the Liver Italian Program (CLIP) score and portal vein thrombosis (PVT) were identified by univariate analyses as prognostic factors for TTP and OS. ECOG PS (hazard ratio [HR], 4.51; 95% CI, 1.61 to 12.6; p=0.004) and PVT (HR, 2.12; 95% CI, 1.10 to 4.11; p=0.026) were independent prognostic factors for TTP. CONCLUSION Cisplatin-based combination chemotherapy in patients with advanced HCC has a low response rate and short TTP regardless of the chemotherapy regimen used. Patients with a good ECOG PS and without PVT can be considered candidates for cisplatin-based combination chemotherapy.

Prognostic prediction across a gradient of total tumor volume in patients with hepatocellular carcinoma undergoing locoregional therapy. BMC Gastroenterol 2010; 10:146.

Abstract
Background The size and number of tumors are important prognostic indicators for hepatocellular carcinoma (HCC). However, it is difficult to assess the prognosis for patients with a variable number and size of tumors. By combining these two factors, we investigated the role and prognostic accuracy of total tumor volume (TTV) for HCC. Methods A total of 786 patients undergoing locoregional therapy (transarterial chemoembolization, percutaneous radiofrequency ablation and acetic acid or ethanol injection) for HCC were prospectively evaluated. Results The mean and median TTV was 177 cm3 (range, 0.1-3,591 cm3) and 21 cm3, respectively. Of all, 38%, 29%, 15%, 7% and 11% of patients had TTV of <10 cm3, 10-50 cm3, 50-200 cm3, 200-500 cm3 and >500 cm3, respectively. TTV was significantly larger in patients with higher serum α-fetoprotein (AFP) levels or with vascular invasion. The Child-Turcotte-Pugh score, performance status, vascular invasion, AFP level and TTV were significant independent prognostic predictors in the Cox proportional hazards model. After adjustment, patients with TTV 50-200 cm3 (relative risk [RR]: 1.74, p = 0.009), 200-500 cm3 (RR: 2.15, p = 0.006) and >500 cm3 (RR: 3.92, p < 0.001) had a significantly increased mortality risk in comparison to patients with TTV <10 cm3. Conclusions TTV is a feasible prognostic predictor across a wide gradient and can be used to predict the mortality risk of HCC. Selecting appropriate cutoffs of TTV may help refine the design of cancer staging system and treatment planning. Future clinical trials of HCC may include this parameter for mortality risk stratification.

Abstract
BACKGROUND Several staging systems have been proposed for hepatocellular carcinoma (HCC); however, none has incorporated circulating angiogenic biomarkers. The purpose of this study was to determine whether vascular endothelial growth factor (VEGF) could independently predict overall survival in patients with HCC, and whether adding VEGF level into the Cancer of the Liver Italian Program (CLIP) score could improve patient stratification and prediction of overall survival. METHODS Between 2001 and 2008, baseline plasma VEGF levels were available from 288 patients, and multivariate Cox regression models and median survival (95% confidence intervals) were calculated. Recursive partitioning was used to determine the optimal cutpoint for VEGF, using 10 repeated training/validation samples, each using two-thirds of the data to determine the best cutpoint and the remaining one-third to validate it. Prognostic ability of CLIP and V-CLIP was compared using the concordence index. RESULTS Plasma VEGF was a significant independent predictor of overall survival, with an optimal VEGF cutpoint of 450 pg/mL. After CLIP validation in our patients, we added VEGF to the CLIP score and found that the new V-CLIP score better separates patients into homogenous prognostic groups (P = .005). CONCLUSIONS The assessment of baseline plasma VEGF levels increases the precision of the CLIP scoring system for predicting HCC prognosis, which may assist in equally randomizing patients with HCC in clinical trials. Prospective validation of the V-CLIP scoring system is warranted.

Abstract
INTRODUCTION The majority of liver resections for malignancy are performed in older patient with major co-morbidities. There is currently no pre-operative, patient-specific method to determine the likely peri-operative mortality for each individual patient. The aim of this study was to develop a pre-operative nomogram based on the presence of co-morbidities to predict risk of peri-operative mortality following liver resections for malignancy. METHODS The Nationwide Inpatient Sample database was queried to identify adult patients that underwent liver resection for malignancy. The pre-operative co-morbidities, identified as predictors were used and a nomogram was created with multivariate regression using Taylor expansion method in SAS software, surveylogistic procedure. Training set (years 2000-2004) was utilized to develop the model and validation set (year 2005) was utilized to validate this model. RESULTS A total of 3,947 and 972 patients were included in training and validation sets, respectively. The overall actual-observed peri-operative mortality rates for training and validation sets were 4.1% and 3.2%, respectively. The decile-based calibration plots for the training set revealed good agreement between the observed probabilities and nomogram-predicted probabilities. Similarly, the quartile-based calibration plot for the validation set revealed good agreement between the observed and predicted probabilities. The accuracy of the nomogram was further reinforced by a good concordance index of 0.80 with a 95% confidence interval of 0.72 and 0.87. CONCLUSIONS This pre-operative nomogram may be utilized to predict the risk of peri-operative mortality following liver resection for malignancy.

Abstract
AIM This study explored recent improvements in the management of hepatocellular carcinoma (HCC) diagnosed during surveillance. METHODS The subjects were 1074 patients with HCC, subdivided into three groups. Group A comprised 211 patients for whom HCC was detected during periodic follow-up examinations at Kurume University School of Medicine, Group B comprised 544 patients diagnosed with HCC during periodic follow-up examinations at other institutions, and, Group C comprised 319 patients with HCC detected incidentally or because of symptoms. RESULTS In 1995-2000 and 2001-2006, 91% and 91% of group A, 68% and 70% of group B, and 27% and 26% of group C patients with HCC, respectively, met the Milan criteria. For groups A and B, the proportions of patients with Child-Pugh class A and use of promising treatment increased in the later periods compared to those diagnosed during the earlier periods (group A, Child-Pugh class A, 72% vs 58% [P = 0.040], receiving treatment, 90% vs 70% [P < 0.0001]; group B, Child-Pugh class A, 71% vs 62% [P = 0.031]; receiving treatment, 72% vs 52% [P < 0.0001], respectively). The cumulative survival rates of the 405 patients with HCC detected in the latter 6 years tended to be better than those for patients diagnosed in the former 6 years (350 patients) (4 years, 58% vs 50% [P = 0.0349]). CONCLUSION The use of promising treatment and prognosis have improved in the last 6 years for patients with HCC diagnosed through surveillance relative to those identified in 1995-2000.

Abstract
BACKGROUND Radiofrequency ablation (RFA) is becoming a well-known local therapy for hepatocellular carcinoma (HCC). Transcatheter arterial chemoembolization (TACE) is expected to enhance the effects of subsequent RFA by reducing arterial blood flow. However, the long-term efficacy of this combined therapy has not been elucidated. In this study, the survival rates of patients who received TACE combined with RFA (TACE + RFA) were compared with those of patients treated surgically. METHODS The study included consecutive patients who received TACE+RFA or surgical resection as the initial curative treatment for HCC between 2000 and 2005 at Tokai University Hospital. Inclusion criteria were a single HCC<or=50 mm or up to 3 HCCs<or=30 mm, presence of cirrhosis classified as Child-Pugh class A, no vascular invasion, and no extrahepatic metastasis. RESULTS Sixty-two patients (23 women, 39 men; aged 67.5+/-8.4 years [mean+/-standard deviation]) received TACE+RFA, and 55 patients (15 women, 40 men; aged 66.1+/-8.4 years) underwent surgical resection. Median follow-up periods were similar (50 months in the TACE+RFA group vs 49 months in the resection group). The probabilities of overall survival at 1, 3, and 5 years in the TACE+RFA group (100%, 94.8%, and 64.6%, respectively) were similar (P=.788) to those in the resection group (92.5%, 82.7%, and 76.9%, respectively). Two major RFA-related complications were observed (1.5%). CONCLUSIONS RFA combined with TACE is an efficient and safe treatment that provides overall survival rates similar to those achieved with surgical resection.

Abstract
BACKGROUND AND AIM A large proportion of hepatocellular carcinoma (HCC) patients do not secrete elevated levels of the tumor marker alpha-fetoprotein (AFP). There is little published guide to prognostic features of this patient subset. METHODS We interrogated a large HCC database in which all patients had been followed until death, to examine which features might be prognostically useful. RESULTS We found 413 biopsy-proven unresectable HCC patients with low serum AFP values. Serum gamma glutamyl transpeptidase (GGTP) levels were one of the most significant factors for survival. This dichotomization into low and high GGTP levels separated the patients into distinctive survival ranges. Patients with GGTP levels < 110 U/100 mL and small tumors had longest survival > 795 days. Patients with GGTP > or = 110 U/mL and large tumors with the presence of portal vein thrombosis had the shortest survival range of 300-560 days. CONCLUSIONS Serum levels of the onco-fetal protein GGTP represent a useful prognostic parameter in HCC patients with low AFP levels.

Abstract
Hepatocelluar carcinoma (HCC) is the most common primary malignancy of the liver in adults and the third most common cause of cancer death worldwide. The incidence of HCC in the United States is rising steadily because of the prevalence of hepatitis C viral infection and other causes of hepatic cirrhosis. The majority of patients have underlying hepatic dysfunction, which complicates patient management and the search for safe and effective therapies. The Clinical Trials Planning Meeting (CTPM) in HCC was convened by the National Cancer Institute's Gastrointestinal Cancer Steering Committee to identify the key knowledge gaps in HCC and define clinical research priorities. The CTPM structured its review according to current evidence-based treatment modalities in HCC and prioritized the recommendations on the basis of the patient populations representing the greatest unmet medical need.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide and one of the few malignancies with an increasing incidence in the USA. Imaging plays a crucial role in early detection, accurate staging and planning management strategies. Contrast material-enhanced MRI or computed tomography (CT) are the best imaging techniques currently available for the noninvasive diagnosis of HCC. The diagnosis of HCC is strongly dependent on hemodynamic features (arterial hypervascularity and washout in the venous phase) on dynamic imaging, and biopsy is no longer recommended for tumors with classical imaging features prior to treatment. The major challenge for radiologists in imaging cirrhosis is the characterization of hypervascular nodules smaller than 2 cm, which often have nonspecific imaging characteristics. In this review, we discuss the role of CT and MRI in the diagnosis and staging of HCC. The strengths and current limitations of these imaging modalities are highlighted.

Abstract
PURPOSE Surgical resection remains the gold standard for hepatocellular carcinoma (HCC). Although various staging systems have been developed in recent years, the best tool for staging of HCC remains controversial. The aims of this study were to establish a new staging for patients with HCC undergoing surgical resection and to identify whether this staging is superior to other staging systems in predicting survival of resectable HCC. METHODS The subjects of this retrospective study were 958 consecutive HCC patients who underwent surgical resection between 2000 and 2006. Predictors of survival were identified using the Kaplan-Meier method and the Cox model. The disease state was staged by our proposed Eastern staging system by integrating independent risk predictors, as well as six existing staging systems. The accuracy of prediction of 1-, 3-, and 5-year mortality for each system was evaluated by the area under the receiver operating characteristic curve (AUC). RESULTS Macroscopic vascular invasion, multiple tumors, performance status 1-2, microscopic vascular invasion, extrahepatic spread, tumor size > 5 cm, albumin < 35 g/L, aspartate aminotransferase > 40 U/L, total bilirubin > 17 μmol/L, and presence of cirrhosis were identified as independent risk factors of survival after resection by multivariate analysis. The comparison of the results of the different staging systems showed that our Eastern staging had the best homogeneity (likelihood ratio χ(2) test 543.51, P < 0.001), monotonicity of gradients (linear trend χ(2) test 414.97, P < 0.001), and discriminatory ability (the highest AUCs for 1-, 3-, and 5-year mortality). CONCLUSIONS Compared with other existing staging systems, our proposed Eastern staging system shows a superior predictive ability in a Chinese cohort of patients with resectable HCC, and it can give important prognostic information after surgery.

Abstract
BACKGROUND AND AIM Locoregional therapies for hepatocellular carcinoma (HCC) are considered to confer a survival advantage, however, the patient group that should be targeted is not clearly defined. This study aimed to determine the impact on survival of locoregional therapies compared with supportive care, within prognostic categories as stratified by the Cancer of the Liver Italian Program (CLIP) scoring system. METHODS A prospective database was used to identify those patients who were treated with either locoregional therapy (n = 128) or supportive care (n = 92). Survival analysis was performed for groups matched by CLIP score at presentation. Comparison of important prognostic factors was undertaken and univariate and multivariate analysis was performed to assess determinants of survival. RESULTS Use of locoregional therapies was only associated with a survival benefit in patients with a CLIP score of 1 or 2. In this group, the median survival in patients who received locoregional therapies was 25.0 months (95% confidence interval 22.7-27.4) compared with 8.9 months (95% confidence interval 7.3-10.5) for supportive care (P = 0.001). For patients with CLIP scores of 3 or greater, no survival benefit of locoregional therapies was observed. Multivariate analysis revealed locoregional intervention, CLIP score, tumor symptoms, alpha-fetoprotein level, bilirubin and alkaline phosphatase level as independent prognostic indicators. CONCLUSION Locoregional therapies should be targeted specifically to patients with non-advanced hepatocellular carcinoma as assessed by validated scoring systems. Use of these therapies in patients with advanced disease does not appear to be associated with a survival benefit and may expose patients to unnecessary harm.

Abstract
Background: Invasion of major hepatic vessels in hepatocellular carcinoma (HCC) generally prohibits the surgical treatment. Objective: Analyze outcomes of non-surgical approaches in this group of HCC. Methods: Retrospective review of medical records of 648 HCC admitted to King Chulalongkorn Memorial Hospital between January 2003 and December 2005 was carried out to select only patients who had unresectable HCC with vascular invasion and hepatic functions-Child-Pugh class-A. Vascular invasion was defined as involvement of portal vein, inferior vena cava (IVC), or their branches identified by imaging techniques. Non-surgical treatments were either transarterial chemoembolization (TACE) or systemic chemotherapy (SCT) in addition to general supportive care. Treatment outcomes of the patients were analyzed. Results: Out of 71 unresectable HCC patients enrolled, 57patients were treated with TACE, while 14 received SCT. In the TACE group, 39 (68%), 7 (12%) and 11 (19%) patients had portal vein, IVC, and both vessels invasion, respectively. In the SCT group; 11 (78%), 1 (7%) and 2 (14%) had invasion of portal vein, IVC, and both vessels, respectively. Median overall survival in both groups was 158 days. Univariate analysis demonstrated that AFP level <1000 ng/mL, tumor size <10 cm, and SCT treatment significantly influenced survival. Additional multivariate analysis confirmed that diameters of tumor, and SCT were independent prognostic factors for good survival. A survival analysis showed longer survival in the SCT group than that of TACE (210 vs. 149 days, p=0.03) group. Conclusion: Survival of HCC patients with major vessels invasion was better when treated with SCT compared to TACE. Future prospective study in larger populations to test the hypothesis is warranted.

Abstract
PURPOSE The purpose of cancer staging systems is to accurately predict patient prognosis. The outcome of advanced hepatocellular carcinoma (HCC) depends on both the cancer stage and the extent of liver dysfunction. Many staging systems that include both aspects have been developed. It remains unknown, however, which of these systems is optimal for predicting patient survival. PATIENTS AND METHODS Patients with advanced HCC treated over a 5-year period at Memorial Sloan-Kettering Cancer Center were identified from an electronic medical record database. Patients with sufficient data for utilization in all staging systems were included. TNM sixth edition, Okuda, Barcelona Clinic Liver Cancer (BCLC), Cancer of the Liver Italian Program (CLIP), Chinese University Prognostic Index (CUPI), Japan Integrated Staging (JIS), and Groupe d'Etude et de Traitement du Carcinome Hepatocellulaire (GETCH) systems were ranked on the basis of their accuracy at predicting survival by using concordance index (c-index). Other independent prognostic variables were also identified. RESULTS Overall, 187 eligible patients were identified and were staged by using the seven staging systems. CLIP, CUPI, and GETCH were the three top-ranking staging systems. BCLC and TNM sixth edition lacked any meaningful prognostic discrimination. Performance status, AST, abdominal pain, and esophageal varices improved the discriminatory ability of CLIP. CONCLUSION In our selected patient population, CLIP, CUPI, and GETCH were the most informative staging systems in predicting survival in patients with advanced HCC. Prospective validation is required to determine if they can be accurately used to stratify patients in clinical trials and to direct the appropriate need for systemic therapy versus best supportive care. BCLC and TNM sixth edition were not helpful in predicting survival outcome, and their use is not supported by our data.

Abstract
The genomic era is changing the understanding of cancer, although translation of the vast amount of data available into decision-making algorithms is far from reality. Molecular profiling of hepatocellular carcinoma (HCC), the most common cause of death among cirrhotic patients and a fast-growing malignancy in Western countries, is enabling the advancement of novel approaches to disease diagnosis and management. Most HCCs arise on a cirrhotic liver, and predictably, an accurate genomic characterization will allow the identification of procarcinogenic signals amenable to selective targeting by chemopreventive strategies. Molecular diagnosis is currently feasible for small tumors, but it has not yet been formalized by scientific guidelines. Molecular treatment is a reality: Sorafenib confers unprecedented survival benefits in patients at advanced stages. Genomic information from tumor and nontumoral tissue will aid prognosis prediction and facilitate the identification of oncogene addiction loops, providing the opportunity for more personalized medicine.

Abstract
Purpose It is well known that hepatocellular carcinoma (HCC) is an arginine auxotroph due to argininosuccinate synthetase I deficiency. This study's purpose was to evaluate the effects of pegylated arginine deiminase (ADI) in terms of toxicity, tumor response, α-fetoprotein (AFP) levels, and serum arginine levels. Patients and Methods Eighty patients were randomly assigned to receive either 80 IU/m2 or 160 IU/m2 of ADI weekly for up to 6 months. Adverse events, serum arginine, AFP levels, and antibody production against ADI were measured on a regular basis. In addition, disease response and time to progression according to the Response Evaluation Criteria in Solid Tumors (RECIST) and survival rates were evaluated. Results Four patients were excluded from the survival analysis because they developed exclusion criteria after randomization, but before first treatment. The number of patients in the two cohorts were similar (n = 37 in the low-dose cohort, n = 39 in the high-dose cohort). Mean (±SE) survival for all subjects was 15.8 months (474 days ± 39 days) from time of diagnosis of unresectable disease. Arginine levels remained below baseline for 50 days while antibodies against ADI reached a plateau at approximately the same time. There were no deaths attributed to ADI treatment. Only two patients were withdrawn for immunogenic-related adverse events. Grade 2, 3, or 4 toxicities were recorded in 92, 19, and 0 patients, respectively. Conclusion Pegylated ADI is a promising drug that capitalizes on a significant enzymatic deficiency in HCC. It is safe, well tolerated, and may benefit patients with unresectable HCC.

Abstract
AIMS To analyze the main etiological factors and some clinical characteristics of patients with HCC at diagnosis and to compare them with those we described ten years ago. METHODS 179 patients were included in Group 1, while 132 patients were included in Group 2. For all patients age, sex, serum markers of hepatitis B and C viruses, alcohol consumption, serum alpha feto-protein (AFP) levels and the main liver function parameters at HCC diagnosis were recorded. RESULTS Mean age was 66.0 years for Group 1 and 69.0 for Group 2 (P=0.005). HCV was responsible for 80.3% of HCC cases in Group 2 versus 72% in Group 1 (P=0.005). HBV alone and co-infection of HCV+HBV decreased, but not significantly. In Group 1 only four patients had an underlying normal liver, while in Group 2 no patients showed an underlying normal liver (P=ns). HCC was more frequently associated with Child class A in Group 2 (P=0.0001), whereas in Group 1 it was more frequently associated with class C (P=0.0001). Staging of HCC correlated inversely when patients of Groups 1 and 2 were compared (P<0.03). AFP serum levels were above normal in 72% of cases in Group 1 and in 41.5% in Group 2 (P=0.0001). CONCLUSION This study shows that over the last decade a number of characteristics of patients with HCC in our region have changed, particularly age at onset of HCC, staging of underlying liver disease and staging of HCC.

Effect of surveillance for hepatocellular carcinoma on tumor staging and treatment decisions in Egyptian patients. Hepatol Int 2010; 4:500-6. [PMID: 20827407 DOI: 10.1007/s12072-010-9170-x] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2009] [Accepted: 12/20/2009] [Indexed: 12/16/2022]
Abstract
PURPOSE Egyptian hepatocellular carcinoma (HCC) patients present at advanced stages. We aimed to study the influence of surveillance versus non-surveillance on HCC staging and the potential therapeutic options. METHODS A retrospective study to evaluate the effect of surveillance on early detection of HCC among cirrhotic patients from 2003 to 2008. Patients examined every 6 months using ultrasound and α-fetoprotein (α-FP) (group A) and those diagnosed with those that present for the first time symptomatically or incidentally (group B). Groups were compared for α-FP level, tumour characteristics, severity of liver disease; tumour staging was evaluated by Okuda, CLIP and BCLC staging systems, in addition to the potential therapeutic options. RESULTS Group A comprised 122 HCC cases and group B 473. Surveillance improved HCC detection: at the stage of single nodule in 62.3% in group A versus 52.2% in group B, (P = 0.046) and reduced the percentage of HCC with portal vein thrombosis in 16.4 versus 33.8%, (P = 0.000) and the percentage of α-FP >400 ng/ml in 19.5 versus 32.6%, (P = 0.006) in groups A and B, respectively. Surveillance doubled the detection of HCC at early stage of BCLC (25.4 vs. 11.9% P = 0.000) and doubled the patients' chance for loco-regional ablation (12.3 vs. 5.9%, P = 0.015) and liver transplantation (10.7 vs. 3.2%, P = 0.001) in groups A and B, respectively. CONCLUSION HCC surveillance increases early detection of HCC and doubled the chances for curative options. Implementation of both HCC surveillance and cadaveric liver transplantation programs should be recommended in Egypt.

Abstract
BACKGROUND Updated National Academy of Clinical Biochemistry Laboratory Medicine Practice Guidelines for the use of tumor markers in the clinic have been developed. METHODS Published reports relevant to use of tumor markers for 4 cancer sites--liver, bladder, cervical, and gastric--were critically reviewed. RESULTS Alpha-fetoprotein (AFP) may be used in conjunction with abdominal ultrasound for early detection of hepatocellular carcinoma (HCC) in patients with chronic hepatitis or cirrhosis associated with hepatitis B or C virus infection. AFP concentrations >200 microg/L in cirrhotic patients with typical hypervascular lesions >2 cm in size are consistent with HCC. After a diagnosis of HCC, posttreatment monitoring with AFP is recommended as an adjunct to imaging, especially in the absence of measurable disease. Although several urine markers have been proposed for bladder cancer, none at present can replace routine cystoscopy and cytology in the management of patients with this malignancy. Some may, however, be used as complementary adjuncts to direct more effective use of clinical procedures. Although carcinoembryonic antigen and CA 19-9 have been proposed for use gastric cancer and squamous cell carcinoma antigen for use in cervical cancer, none of these markers can currently be recommended for routine clinical use. CONCLUSIONS Implementation of these recommendations should encourage optimal use of tumor markers for patients with liver, bladder, cervical, or gastric cancers.
