RESUMO

Monotherapy with interferon or nucleoside analog is generally not recommended during the immune-tolerant (IT) phase of chronic hepatitis B virus (HBV) infection. Recognition that high HBV DNA levels are associated with hepatocellular carcinoma has increased interest in treating HBV in the IT phase. Small pediatric studies reported efficacy with combination nucleoside analog and interferon therapy. The aim of this study was to evaluate the safety and efficacy of the combination of entecavir and peginterferon in adults in the IT phase of chronic HBV infection. Hepatitis B e antigen (HBeAg)-positive adults with HBV DNA > 107 IU/mL and alanine aminotransferase (ALT) ≤ 1.5 times the upper limit of normal (ULN) (male: ≤ 45, female: ≤ 30 U/L) received entecavir 0.5 mg daily for 8 weeks followed by the addition of peginterferon alfa-2a 180 µg/week to entecavir for an additional 40 weeks. The primary endpoint was HBeAg loss and HBV DNA ≤ 1,000 IU/mL 48 weeks after end of treatment (EOT). Among 28 participants from 11 sites, the median age was 37.2 (range: 22-61) years, 54% were male, and 96% were Asian. Nearly all were infected with genotype C (64%) or B (32%). Median baseline HBV DNA was 8.2 log10 IU/mL, and ALT was 0.9 times the ULN. Although one (4%) participant cleared HBeAg, none met the primary endpoint of both HBeAg loss AND HBV DNA ≤ 1,000 IU/mL 48 weeks post-EOT. ALT elevations > 5 times the ULN occurred in eight (29%) participants, and none were associated with icterus. Forty-eight weeks posttreatment, HBV DNA rebounded to baseline levels in all participants, including the participant who lost HBeAg, and ALT values returned to near baseline levels in all but four participants. Conclusion: A lead-in strategy of 8 weeks of entecavir followed by combination peginterferon and entecavir therapy for 40 weeks had limited efficacy in adults in the IT phase of chronic HBV infection and cannot be recommended.

RESUMO

Purpose To determine the relationship between hepatic uptake at preoperative fluorine 18 (18F) fluorocholine combined positron emission tomography (PET) and computed tomography (CT) and the histopathologic features of chronic liver disease in patients with Child-Pugh class A or B disease who are undergoing hepatic resection for liver cancer. Materials and Methods Forty-eight patients with resectable liver tumors underwent preoperative 18F fluorocholine PET/CT. Mean liver standardized uptake value (SUVmean) measurements were obtained from PET images, while histologic indexes of inflammation and fibrosis were applied to nontumor liver tissue from resection specimens. Effects of histopathologic features on liver SUVmean were examined with analysis of variance. Results Liver SUVmean ranged from 4.3 to 11.6, correlating significantly with Knodell histologic activity index (ρ = -0.81, P < .001) and several clinical indexes of liver disease severity. Liver SUVmean also differed significantly across groups stratified by necroinflammatory severity and Metavir fibrosis stage (P < . 001). The area under the receiver operating characteristic curve for 18F fluorocholine PET/CT detecting Metavir fibrosis stage F1 or higher was 0.89 ± 0.05, with an odds-ratio of 3.03 (95% confidence interval: 1.59, 5.88) and sensitivity and specificity of 82% and 93%, respectively. Conclusion Correlations found in patients undergoing hepatic resection for liver cancer between liver 18F fluorocholine uptake and histopathologic indexes of liver fibrosis and inflammation support the use of 18F fluorocholine PET/CT as a potential imaging biomarker for chronic liver disease. © RSNA, 2018.

RESUMO

BACKGROUND/AIMS: Surveillance for hepatocellular carcinoma (HCC) with ultrasound in high-risk populations is generally believed to improve opportunities for treatment. However, tumors are still missed due to various factors. This study explores success versus failure of HCC surveillance. METHODS: This is a retrospective study of 1,125 HCC cases. Categories considered for successful detection were largest tumor ≤3.0 cm, single tumors ≤3.0 cm and ≤2.0 cm, and adherence to Milan criteria. Examined factors were age <60 years, gender, rural residence, body-mass index (BMI), hepatitis infection, smoking, diabetes, hyperlipidemia, cirrhosis, ascites, and Model for End-Stage Liver Disease <10. RESULTS: HCC was found on surveillance in 257 patients with a mean tumor size of 3.17 cm; multiple tumors were seen in 28% of cases, bilateral tumors in 7.4%, and vascular invasion in 3.7%. Surveillance was successful in 61.5% of cases involving a largest tumor ≤3.0 cm, with BMI ≥35 negatively affecting detection (odds ratio [OR] 0.28, P=0.014) and cirrhosis positively affecting detection (OR 2.31, P=0.036). Ultrasound detected 19.1% of single tumors ≤2.0 cm with ascites improving the detection rate (OR 3.89, P=0.001). Finally, adherence to Milan criteria occurred in 75.1% of cases, revealing negative associations with diabetes (OR 0.48, P=0.044 and male gender (OR 0.49, P=0.08). CONCLUSIONS: Although surveillance is recommended for HCC, not all surveillance ultrasound are ideal. Tumor detection can depend on gender, BMI, diabetes, cirrhosis, and ascites and is achieved in 19.1-75% of cases depending on the definition of success. Closer follow-up or additional imaging might be necessary for some patient subgroups.

RESUMO

Eight weeks duration of ledipasvir/sofosbuvir (LDV/SOF) can be considered in genotype 1 hepatitis C virus-infected patients who are treatment-naive, do not have cirrhosis, and have a pretreatment viral load <6,000,000 IU/mL. The effectiveness of this regimen, however, has not been fully confirmed by real-world experience. Using data from real-world cohorts, we aimed to determine the effectiveness of 8 weeks of LDV/SOF treatment, examine variables associated with relapse after treatment with this regimen, and compare the effectiveness of 8 weeks and 12 weeks of LDV/SOF treatment. To evaluate the effectiveness of 8 weeks of therapy and characteristics associated with relapse, we used individual patient data from the IFI (Institut für Interdisziplinäre Medizin), Burman's Pharmacy, and Kaiser Permanente Southern California. All patients had fibrosis staging assessed with biopsy, transient elastography, or serum biomarkers. We also performed a systematic review and meta-analysis of six additional real-world cohorts, to compare effectiveness of 8 weeks to 12 weeks duration. In our pooled data analysis, 634 patients were treated for 8 weeks with LDV/SOF, of whom all had outcomes of cure or relapse without loss to follow-up. Per protocol rates of sustained virologic response at 12 weeks were 98.1% (622/634) in the full cohort and 97.9% (571/583) among treatment-eligible patients. Exact logistic regression revealed no specific patient characteristics associated with relapse. Our meta-analysis of six additional real-world cohorts, comprised of 5,637 patients, demonstrated similar risk for relapse between 8 weeks and 12 weeks of LDV/SOF (relative risk = 0.99, 95% confidence interval 0.98-1.00). CONCLUSION: An 8-week duration of treatment with LDV/SOF is highly effective in properly selected patients; greater use of this regimen is recommended. (Hepatology 2017;65:1094-1103).

RESUMO

Hepatocellular carcinoma (HCC) incidence has steadily increased in the US over the past 30 years. Our understanding of epigenetic regulation in HCC is still limited, especially the impact of hepatitis B virus (HBV) or hepatitis C virus (HCV) infection on aberrant DNA methylation. We performed genome-wide DNA methylation profiling in 33 fresh frozen tumor samples, including 10 HBV-HCC, 13 HCV-HCC, and 10 non-infected (NIV-HCC) using the Illumina HumanMethylation450 BeadChip. Gene expression profiling was also performed using the Illumina whole-genome DASL HT Assay. Biological influences and gene networks of the differentially-methylated (DM) CpG loci were predicted using the Ingenuity Pathway Analysis. Genome-wide methylation analysis identified 7, 26, and 98 DM loci between HBV-HCC vs. HCV-HCC, HBV-HCC vs. NIV-HCC, and HCV-HCC vs. NIV-HCC, respectively, at P < 5 × 10(-5) for each. Overall, the DM loci were highly enriched for enhancers (48%), promoters (37%), or CpG islands and surrounding regions (37%). Most DM loci were hypermethylated in HCV-HCC compared to HBV-HCC or NIV-HCC. The DM loci were associated with a variety of biological functions including Cell Morphology (HBV-HCC vs. NIV-HCC), Cell Death/ Survival (HBV-HCC vs. NIV-HCC), or Cellular Growth and Proliferation (HCV-HCC vs. NIV-HCC). A subset of the DM loci were correlated (either positively or negatively) with their gene expression or associated with alcohol consumption, BMI, cirrhosis, diabetes, and cigarette smoking. Our findings of differential methylation by viral infection lend insights into the potential effects of viral infection on the epigenetic regulation and further the development and progression of HCC.

RESUMO

Positron emission tomography (PET) using the radiopharmaceutical tracer fluorine-18 fluorocholine (FCh) can elucidate tumors based on differences in choline phospholipid metabolism between tumor and surrounding tissue. The feasibility of detecting hepatocellular carcinoma (HCC) using FCh PET has been shown despite constitutively high parenchymal choline metabolism in the liver. Since HCC frequently develops in the setting of chronic liver disease, we comparatively evaluated FCh PET/CT between cirrhotic and non-cirrhotic patients with HCC to investigate the effects of hepatic dysfunction on tumor detection and the tumor-to-background ratio (TBR) of FCh uptake. FCh PET/CT was performed prospectively in 22 consecutive patients with HCC (7 newly diagnosed, 15 previously treated). Of these 22 patients, 14 were cirrhotic and 8 non-cirrhotic. Standardized uptake value (SUV) measurements were obtained by region of interest analysis of the PET images. Tumor FCh uptake and the TBR were compared between cirrhotic and non-cirrhotic patients. Liver lesions were confirmed to be HCC by biopsy in 10 patients and by Barcelona criteria in 4 patients. There was correspondingly increased liver tumor FCh uptake in 13/14 of those patients, and iso-intense tumor FCh uptake (TBR 0.94) in one non-cirrhotic patient with newly diagnosed HCC. FCh PET/CT also showed metastatic disease without local tumor recurrence in 2 previously treated patients, and was negative in 6 treated patients without tumor recurrence by radiographic and clinical follow-up. Tumor maximum SUV ranged from 6.4 to 15.3 (mean 12.1) and liver TBR ranged from 0.94 to 2.1 (mean 1.6), with no significant differences between cirrhotic and non-cirrhotic patients (SUVmax 11.9 vs. 12.2, p = 0.83; TBR 1.71 vs. 1.51, p = 0.29). Liver parenchyma mean SUV was significantly lower in cirrhotic patients (6.4 vs. 8.7, p < 0.05). This pilot study supports the general feasibility of HCC detection by FCh PET/CT. However, a broad range of tumor FCh uptake was observed, and lower liver parenchymal uptake of FCh was noted in cirrhotic patients as compared to non-cirrhotic patients. Incorporating tissue profiling into future liver imaging trials of FCh PET may help determine the molecular basis of the observed variations in tumor and hepatic FCh uptake.

RESUMO

BACKGROUND: The incidence of hepatocellular cancer (HCC) is increasing, and we sought to characterize the differences and trends in HCC over 2 decades in Hawaii. METHODS: This retrospective study of 821 HCC cases analyzed risk factors, diabetes, alpha-fetoprotein (AFP), tumor characteristics, and treatment, comparing 5-year eras (1993 to 2012). RESULTS: With succeeding eras, there were fewer Asians, immigrants, and hepatitis B-related HCC. Hepatitis C, diabetes, hyperlipidemia, and body mass index have increased. Over time, more patients had normal AFP, and normal AFP was seen more often in nonviral HCC (49.6% vs 33.2%, P = .007). Over time, the proportion of patients who underwent resection or transplant was stable, but fewer patients underwent no therapy. CONCLUSIONS: Characteristics of HCC are changing, and diagnosis may be more difficult as metabolic factors are becoming more important than viral factors. AFP seems to be a less important biomarker, and clearly, better diagnostic tools will be necessary to identify HCC in the future.

RESUMO

BACKGROUND/AIM: Treatment practices for patients with chronic hepatitis B (CHB) varies across the world and several professional associations have issued treatment recommendations. This synopsis aims to review the major principles of CHB and its management, and to systematically summarize and compare the recommendations of the major treatment guidelines by: the Asian-Pacific Association for the Study of the Liver, the US Panel, the European Association for the Study of the Liver, and the American Association for the Study of the Liver. METHODS: Treatment recommendations were summarized separately for hepatitis B e antigen (HBeAg)-positive and HBeAg-negative patients. CONCLUSIONS: Treatment for CHB is recommended on the basis of a variety of host and viral factors, and the ultimate goal of treatment is the prevention of decompensated liver disease, hepatocellular carcinoma, cirrhosis, and premature death. Despite updates and improvements in these guidelines during the past decade, greater patient and physician education as well as better noninvasive markers to identify high-risk patients are still needed. Significant improvements in the application of current practice guidelines, however, can be made by relatively simple educational efforts, and new molecular and genomic techniques may hold promise for more accurate selection of high-risk patients for further therapeutic interventions in a near future.

RESUMO

This is a case report series of four patients who exhibited signs and symptoms of acute liver dysfunction during participation in a Phase I trial of a novel non-steroidal anti-inflammatory drug (NSAID) designed to inhibit microsomal prostaglandin synthase 1 (MPGES1). Within one month of trial initiation, all four patients presented with epigastric pain, fatigue, nausea, and increasing liver function tests (LFTs). Two out of four patients required hospitalization, underwent liver biopsies, and were treated with N-acetylcysteine. The remaining two patients were managed as outpatients. Liver biopsies were consistent with drug induced liver injury (DILI). Within three months of stopping the investigational drug, symptoms subsided and LFTs normalized in all patients. This case report series signifies the importance of NSAIDs and novel drug agents in general as potentially hepatotoxic substances, the need for a high level of suspicion of DILI when considering possible etiologies of acute liver failure, and the need for prompt withdrawal of the causative agent in management of patients presenting with DILI.

RESUMO

BACKGROUND: Hepatocellular carcinoma (HCC) incidence is increasing in the United States. Hepatitis B virus (HBV) and hepatitis C virus (HCV) are major causes of HCC. Hepatitis infection in patients with HCC is generally diagnosed by serology, which is not always consistent with the presence of HBV and HCV in the liver. The relationship of liver viral status to serostatus in hepatocarcinogenesis is not fully understood. METHODS: HBV and HCV were evaluated in formalin-fixed, paraffin-embedded liver tissue specimens in a retrospective study of 61 U.S. HCC cases of known serologic status. HBV DNA and HCV RNA were detected by PCR, reverse transcription PCR (RT-PCR), and pyrosequencing, and HBsAg and HBcAg were evaluated by immunohistochemistry. RESULTS: Viral markers were detected in the liver tissue of 25 of 61 (41%) HCC cases. Tissue viral and serologic status were discordant in 27 (44%) cases, including those with apparent "occult" infection. Specifically, HBV DNA was detected in tissue of 4 of 39 (10%) serum HBsAg (-) cases, including 1 anti-HCV(+) case; and HCV RNA was detected in tissue of 3 of 42 (7%) anti-HCV seronegative cases, including two with serologic evidence of HBV. CONCLUSIONS: Viral hepatitis, including HBV-HCV coinfection, may be unrecognized in up to 17% of patients with HCC when based on serology alone. Further research is needed to understand the clinical significance of viral makers in liver tissue of patients with HCC in the absence of serologic indices. IMPACT: The contribution of HBV and HCV to the increasing incidence of HCC in the United States may be underestimated.

RESUMO

Of the estimated 400 million patients with chronic hepatitis B (CHB) globally, approximately 75% are Asians, representing a clinically important subgroup with a higher risk of cirrhosis and hepatocellular carcinoma than Caucasian patients. This review summarizes recent data from clinical long-term and real-life studies of entecavir and tenofovir, the recommended first-line oral therapies for treating CHB, in nucleoside/nucleotide-naive Asian CHB patients with compensated or decompensated liver disease. Long-term treatment with entecavir or tenofovir achieved profound and durable virological suppression, and led to improved liver histology and function. The data presented in this review will help physicians in making evidence-based decision choices regarding first-line antiviral therapy and long-term management in Asian CHB patients.

RESUMO

BACKGROUND: Decompensated cirrhosis is a serious clinical complication of chronic hepatitis B (CHB) that places a large economic burden on the US health care system. Although entecavir has been shown to improve health outcomes in a cost-effective manner in mixed populations of CHB patients, the cost-effectiveness of entecavir has not been evaluated in CHB patients with decompensated cirrhosis. METHODS: This study assessed the cost-effectiveness of entecavir versus adefovir, from a US payer perspective, in CHB patients with decompensated cirrhosis, using a health-state transition Markov model with four health states: hepatocellular carcinoma (HCC), HCC-free survival, post-liver transplant, and death. The model considered a hypothetical patient population similar to that included in a randomized controlled trial in the target population (ETV-048): predominantly male (74%), Asian (54%), mean age 52 years, hepatic decompensation (Child-Pugh score ≥ seven), hepatitis B e antigen-positive or -negative, treatment-naïve or lamivudine-experienced, and no liver transplant history. Clinical inputs were based on cumulative safety results for ETV-048 and published literature. Costs were obtained from published literature. Costs and outcomes were discounted at 3% per annum. RESULTS: For 1000 patients over a 3-year time horizon, predicted overall survival and HCC-free survival were longer with entecavir than with adefovir (2.35 versus 2.30 years and 2.11 versus 2.03 years, respectively). Predicted total health care costs were $889 lower with entecavir than with adefovir ($91,878 versus $92,768). For incremental cost/life-year gained and incremental cost/HCC-free-year gained, entecavir was less costly and more effective than adefovir. Sensitivity analyses found the results to be robust to plausible variations in health-state costs and discount rate. CONCLUSION: This analysis suggests that entecavir improves survival outcomes in a cost-saving manner compared with adefovir in CHB patients with hepatic decompensation.

RESUMO

BACKGROUND: Hawaii has the highest incidence of hepatocellular cancer (HCC) in the United States and the largest proportion of Asians and Pacific Islanders. HCC studies generally combine these groups into 1 ethnicity, and we sought to examine differences between Asian and Pacific Islander subpopulations. METHODS: Demographic, clinical, and treatment data for 617 patients with HCC (420 Asians, 114 whites, and 83 Pacific Islanders) were reviewed. Main outcome measures included HCC screening and liver transplantation. RESULTS: Asian and Pacific Islander subgroups had significantly more immigrants, and age was different between groups. Compared with whites, Pacific Islanders and Filipinos had less HCC screening and liver transplantation procedures, fewer met Milan criteria, and a smaller proportion of those with Milan criteria actually underwent transplantation. CONCLUSIONS: There were significant differences in risk factors, clinical presentation, treatment, and access to care among Asian, Pacific Islander, and white patients with HCC. Future HCC studies may benefit from differentiating subgroups within Asian and Pacific Islander populations to better focus these efforts.

RESUMO

Increasing numbers of patients with non-alcoholic steatohepatitis (NASH) are referred for liver transplant (LT). Our objective was to characterize patients with NASH among referred LT candidates (from 1998 to 2008), and we compared demographics, etiology of liver disease, diabetes, hypertension, smoking, obesity, cardiac disease, cancer, laboratory data, model for end-stage liver disease (MELD), and outcomes between NASH and non-NASH patients. Patients with NASH (n = 71) were compared to other chronic liver disease (n = 472). Patients with NASH were older (58.7 vs. 52.5 yr, p < 0.0001), Asian (53.5% vs. 34.7%, p = 0.03) and women (50.7% vs. 32.1%, p = 0.003). Patients with NASH had more diabetes, hypertension, obesity, cardiac disease, and smoking history (p < 0.05). Patients with NASH were equally likely to have liver cancer, but more likely to have non-liver cancers (20.8% vs. 4.4%, p = 0.008). There was no difference in MELD, but patients with NASH had lower protime/international normalized ratio (1.14 vs. 1.27, p = 0.04) and higher creatinine (1.26 vs. 0.98 mg/dL, p = 0.0018). Patients with NASH were equally likely to undergo evaluation, listing, and transplantation compared to non-NASH patients. While all patients with chronic liver disease can have renal dysfunction because of hepatorenal syndrome, patients with NASH have more renal dysfunction, perhaps related to diabetes, hypertension, and cardiovascular disease. Transplant centers should consider this carefully in selection of candidates for LT.

RESUMO

A randomized, open-label comparative study of entecavir versus adefovir therapy was performed in subjects with chronic hepatitis B who had hepatic decompensation (Child-Turcotte-Pugh score ≥7). Adult subjects were randomized and treated (n = 191) with entecavir 1.0 mg or adefovir 10 mg daily for up to 96 weeks from the date of last subject randomization. Subjects were positive or negative for hepatitis B e antigen and experienced or naive for treatment with nucleos(t)ide analogues. The primary efficacy endpoint was the mean reduction in serum hepatitis B virus (HBV) DNA, as determined by polymerase chain reaction, at week 24, adjusted for baseline HBV DNA and lamivudine resistance status by linear regression analysis. Entecavir demonstrated superiority to adefovir for this endpoint (treatment difference 1.74 log(10) copies/mL [95% confidence interval -2.30, -1.18]; P < 0.0001). The entecavir group showed a greater change from baseline in HBV DNA at all time points through week 48 and a higher proportion of subjects who achieved HBV DNA < 300 copies/mL at weeks 24 (entecavir 49%; adefovir 16%; P < 0.0001) and 48 (entecavir 57%; adefovir 20%; P < 0.0001). Approximately two-thirds of subjects in both groups showed improvement/stabilization in Child-Turcotte-Pugh status. Model for End-Stage Liver Disease score change at week 48 was -2.6 for entecavir and -1.7 for adefovir. Adverse event rates were comparable between groups. Cumulative hepatocellular carcinoma rates were 12% for entecavir and 20% for adefovir. Cumulative death rates were 23% for entecavir and 33% for adefovir. Week 24 mortality rates were 12% for both groups. conclusion: Entecavir demonstrated superior virologic efficacy to adefovir in a population of patients with chronic hepatitis B who had hepatic decompensation. Biochemical and clinical benefits were also demonstrated. Entecavir was well tolerated, and early mortality rates were consistent with rates observed in similar populations treated with lamivudine.

RESUMO

One hundred and two liver transplants have been performed since the program's inception in Hawai'i in 1993. Viral hepatitis continues to be the primary indication for liver transplant, though hepatocellular cancer is involved in 23.5% of cases. One, 3 and 5-year patient survival rates have been 88%, 79%, and 74% respectively which is comparable to mainland centers and national data.

RESUMO

BACKGROUND & AIMS: Treatment of chronic hepatitis B (CHB) involves a number of complex and controversial issues. Expert opinions may differ from those of practicing hepatologists and gastroenterologists. We aimed to explore this issue further after a critical review of the literature. METHODS: A panel of 14 international experts graded the strength of evidence for 16 statements addressing 3 content areas: patient selection, therapeutic end points, and treatment options. Available data relating to the statements were reviewed critically in 3 small work groups. After discussion of each statement with the entire panel, the experts voted anonymously to accept or reject statements based on the strength of evidence and their experience. A total of 241 members of the American Association for the Study of Liver Diseases (AASLD) responded to the same statements and their responses were compared with those of the experts. A discordant response was defined as a difference of more than 20% in any of the 5 graded levels of response (accept or reject) between the 2 groups. RESULTS: With the exception of 2 statements, the experts' responses were relatively uniform. However, the responses of the AASLD members were discordant from the experts in 12 statements, spanning all 3 content areas. CONCLUSIONS: Several areas of disagreement on the management of CHB exist between experts and AASLD members. Our results indicate a potential knowledge gap among practicing hepatologists. Better educational efforts are needed to meet the challenge of managing this complex disorder in which even expert opinion occasionally may disagree.

RESUMO

AIM: In the USA, Hawaii has the highest incidence of hepatocellular carcinoma (HCC) and a diverse population. It is an ideal place to characterize HCC in the context of ethnicity/risk factors. METHODS: A total of 262 cases of HCC (1992-2003) were retrospectively reviewed for demographics, ethnicity, birthplace, viral hepatitis, alcohol use, diabetes, smoking and risk factors for viral hepatitis such as intravenous drug abuse (IVDA), transfusions, tattoos and vertical transmission. Tumor stage, Child's class, Cancer of the Liver Italian Program (CLIP) score, alpha-fetoprotein level, treatment and survival were recorded. RESULTS: Gender, age, viral hepatitis, alcohol, IVDA, and diabetes differed significantly in Asians, non-Asians and Pacific Islanders. There were also specific differences within Asian subgroups. Alpha-fetoprotein, smoking, transfusions, stage and resectability did not differ between groups. Asians were more likely to have hepatitis B, while non-Asians were more likely to have hepatitis C. Factors that decreased survival included hepatitis B, alcohol, elevated alpha-fetoprotein, CLIP>2 and increased Child's class. When Asians were combined with Pacific Islanders, median survival (1.52 years vs 3.54 years), 1- and 3-year survival was significantly worse than those for non-Asians. After Cox regression analysis for hepatitis B and alcohol, there was no difference in survival by ethnicity. CONCLUSION: Various ethnicities have different risk factors for HCC. Hepatitis B, alcohol, and alpha-fetoprotein are more important factors for survival than ethnicity.
