Abstract
Direct acting antiviral (DAA) treatments may reduce the elevated α fetoprotein (AFP), but data on how these treatments affect elevated AFP in patients with chronic hepatitis C (CHC) remain insufficient. In the present study, the frequency of baseline AFP elevations and their related factors, AFP dynamics during and after DAA treatment, and factors associated with AFP reduction was assessed. This retrospective study included 141 patients with CHC without hepatocellular carcinoma who received DAA and achieved sustained virological response. The details are as follows: mean post-treatment follow-up was 99 weeks (12-213); mean age, 57.8 years old; 52%, males; 79%, genotype (GT) 1; and 47%, cirrhosis. Pre-treatment AFP elevation (> 5.5 ng/mL) was seen in 48.2% patients. On multivariate analysis, baseline AFP > 5.5 was associated with the presence of cirrhosis (P =0.001), coexisting non-alcoholic steatohepatitis (NASH) (P = 0.035), and GT 1 (P = 0.029). AFP normalization was seen in 28.2% patients at treatment week 2, in 52% at the end of treatment, and in 73.4% at the end of follow-up. Post-treatment week 24 AFP normalization was associated with the absence of cirrhosis (P = 0.003), Child-Pugh score < 6 (P = 0.015), and baseline AFP < 10 (P = 0.015). AFP elevation is common in patients with CHC and independently associated with NASH, cirrhosis, and GT 1. DAA treatment resulted in AFP normalization as early as treatment week 2. Post-treatment week 24 AFP normalization is independently associated with the absence of cirrhosis, Child-Pugh score < 6, and baseline AFP < 10.

Abstract
Chronic hepatitis B virus (HBV) and chronic hepatitis C virus (HCV) are associated with hepatic fibrosis and development of hepatocellular carcinoma (HCC). There are differences and variation with the incidence of HCC worldwide. Additionally, HCC develops via different pathways with these viral hepatitides. This review outlines the various mechanisms and pathophysiology that contributes to this process. There will also be a review on the recommended screening for HCC. Treatment considerations, which are different for these viruses, will be outlined in this review.

Decrease of Alpha-fetoprotein in Patients with Cirrhosis Treated with Direct-acting Antivirals. J Clin Transl Hepatol 2017; 5:43-49. [PMID: 28507926 PMCID: PMC5411356 DOI: 10.14218/jcth.2016.00057] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/03/2016] [Revised: 01/26/2017] [Accepted: 02/01/2017] [Indexed: 12/11/2022] Open
Abstract
Background and Aims: The lack of specificity has limited the role of serum alpha-fetoprotein (AFP) for hepatocellular carcinoma (HCC) screening among patients with cirrhosis related to hepatitis C virus (HCV) infection. We sought to examine whether AFP may decrease after achieving a sustained virological response (SVR) in patients with HCV-related cirrhosis. Methods: We performed a retrospective study of patients with HCV-related cirrhosis who were cured with direct-acting antiviral (DAA) therapy at the University of California, Los Angeles. Laboratory values, including serum AFP, were measured before and after completing the DAA treatment. Results: Fifty-six patients met the inclusion criteria, with median (interquartile range [IQR]) age of 67 (58-69) years and with 51.8% being male. All patients received DAA therapy without interferon. AFP decreased from median (IQR) 7.2 (4.2-13.4) ng/mL before DAAs to 4.2 (2.7-6.3) ng/mL at the end of treatment and 4.2 (2.9-6.8) ng/mL at 12 weeks after treatment (p < 0.001). Model for end-stage liver disease (MELD), fibrosis-4 (FIB4), and aspartate transaminase (AST) to platelet ratio index (APRI) scores at baseline were not significantly associated with AFP reduction. On multivariate analysis, platelet count, AST and total bilirubin at baseline were significantly correlated to AFP reduction (p = 0.04, 0.009 and 0.04, respectively). The higher the baseline AFP, the greater the reduction in AFP. There was no statistically significant correlation between baseline AFP and MELD, FIB4 or APRI scores. Conclusion: There was a significant decrease in AFP in patients with cirrhosis who achieved a SVR with DAAs. Given a reduction in AFP after DAA treatment, AFP should be further studied as a screening modality for HCC in patients with cirrhosis.

A case of successful treatment with telaprevir-based triple therapy for hepatitis C infection after treatment failure with vaniprevir-based triple therapy. J Infect Chemother 2014; 20:577-81.

Abstract
Recently direct-acting antiviral agents, such as hepatitis C virus (HCV) non-structural 3/4A (NS3/4A) protease inhibitors (PI), have been introduced, and triple therapy regimens that include PI with conventional pegylated interferon α and ribavirin have significantly improved the sustained virological response (SVR) rate, up to 80% for both treatment-naïve and treatment-experienced patients with HCV genotype 1. We here report for the first time a case of the successful treatment of HCV genotype 1 infection with a first generation PI drug (telaprevir) based triple therapy after treatment failure with a second generation PI drug (vaniprevir) based triple therapy. A 67-year-old treatment-naïve Japanese man with HCV genotype 1b infection took part in a phase III clinical trial of vaniprevir-based triple therapy. His serum HCV RNA had become undetectable at week 2 and SVR was highly expected, but HCV RNA reappeared at week 4 after vaniprevir treatment. Polymerase chain reaction direct sequence of the HCV NS3/4A gene at week 8 after vaniprevir treatment showed the emergence of a vaniprevir-resistance mutation (D168V), the probable reason for the treatment failure. Six months later, retreatment with telaprevir-based triple therapy was started. Although the dosages of telaprevir and ribavirin had to be reduced due to severe anemia, the patient achieved an SVR. This case shows the value of repeating PI-based triple therapy with a different drug, a process that would reduce the chance of drug resistant mutation.

Abstract
BACKGROUND & AIMS In patients with chronic hepatitis C virus (HCV) infection, lack of sustained virologic response (SVR) 24 weeks after the end of interferon therapy is a significant risk factor for hepatocellular carcinoma (HCC). Although many pretreatment factors are known to affect HCC incidence, less is known about post-treatment factors-many change during the course of interferon therapy. METHODS We performed a prospective study, collecting data from 2659 patients with chronic hepatitis C without a history of HCC who had been treated with pegylated interferon (Peg-IFN) plus ribavirin from 2002 through 2008 at hospitals in Japan. Biopsy specimens were collected before treatment; all patients received Peg-IFN plus ribavirin for 48 to 72 weeks (HCV genotype 1) or 24 weeks (HCV genotype 2). Hematologic, biochemical, and virologic data were collected every 4 weeks during treatment and every 6 months after treatment. HCC was diagnosed based on angiography, computed tomography, and/or magnetic resonance imaging findings. RESULTS HCC developed in 104 patients during a mean observation period of 40 months. Older age, male sex, lower platelet counts and higher levels of α-fetoprotein at baseline, and lack of an SVR were significant risk factors for HCC. The cumulative incidence of HCC was significantly lower in patients without SVRs who relapsed than those with no response to treatment. Levels of α-fetoprotein 24 weeks after the end of treatment (AFP24) were significantly lower than levels of α-fetoprotein at baseline in patients with SVRs and those who relapsed, but not in nonresponders. Post-treatment risk factors for HCC among patients with SVRs included higher AFP24 level and older age; among those without SVRs, risk factors included higher AFP24 level, integrated level of alanine aminotransferase, older age, and male sex. AFP24 (≥10 ng/mL, 10-5 ng/mL, and then <5 ng/mL) was a better predictor of HCC incidence than pretreatment level of AFP among patients with and without SVRs. CONCLUSIONS In patients with chronic HCV infection, levels of α-fetoprotein decrease during interferon therapy. High post-treatment levels of α-fetoprotein predict HCC, regardless of whether patients achieve an SVR.

Abstract
Type I interferons (IFN-α/β), with or without ribavirin, have been the only agents that can eradicate the hepatitis C virus (HCV). An IFN-free regimen combining oral direct-acting antiviral agents (DAA) will be approved soon for genotype 1 patients. Here, we discuss the role of IFN-α/β in the forthcoming "era of DAA" with consideration of limitations and concerns about IFN-free therapies. First, the therapeutic efficacy of first-generation DAA varies among the different subtypes. While the rate of sustained virological response (SVR) is 60-90% among patients with genotype 1b, the rate often falls short of 50% in patients with genotype 1a. IFN and ribavirin can still be indicated for patients with genotype 1a as a platform for combination with DAA. Second, there is concern about the emergence of drug-resistance resulting from inappropriate use of DAA. The clinical significance of pre-existing resistant variants has not been elucidated. Drug resistance may affect the efficacy of next-generation treatments. An IFN and ribavirin backbone in combination with DAA is an effective measure to prevent the emergence of drug resistance and/or to suppress pre-existing resistant viruses. Third, it remains unknown whether the incidence of hepatocellular carcinoma (HCC) will be reduced in patients who achieve SVR with IFN-free regimens. In contrast, there are many reports in Japan demonstrating the preventive effects of IFN on the development of HCC. When patients do not achieve SVR with first-generation DAA, low-dose IFN maintenance therapy is a treatment option until the next-generation therapy with pan-genotypic potency and high genetic barrier become available.

Abstract
Background and Aims. To examine the changes in serum alpha-fetoprotein (AFP) levels after iron reduction by therapeutic phlebotomy in chronic hepatitis C patients. Methods. This retrospective study included 26 chronic hepatitis C patients. The patients were developed iron depletion by repeated therapeutic phlebotomies. Results. Iron reduction therapy significantly reduced the median level of serum AFP from 13 to 7 ng/mL, ALT from 96 to 50 IU/L, gamma-glutamyl transpeptidase (GGT) from 55 to 28 IU/L, and ferritin from 191 to 10 ng/mL (P < 0.001 for each). The rate of decline in the AFP level correlated positively only with that in GGT (r = 0.695, P = 0.001), although a spurious correlation was observed between the rates of decline for AFP and ALT. The AFP level normalized (<10 ng/mL) posttreatment in eight (50%) of 16 patients who had elevated pretreatment AFP levels. Normalized post-treatment ALT and GGT levels were seen in 12% (3 of 26) and 39% (7 of 18) of the patients, respectively. Multivariate analysis identified a post-treatment GGT level of <30 IU/L as an independent factor associated with post-treatment AFP normalization (odds ratio, 21; 95% confidence interval, 1.5-293; P = 0.024). Conclusions. Iron reduction by therapeutic phlebotomy can reduce serum AFP and GGT levels in chronic hepatitis C patients.

Abstract
BACKGROUND Serum vitamin D concentration is reported to show a decrease in older age. Patients with chronic hepatitis C (CHC) in Japan are older on average than those in Western countries. Moreover, the outcome of pegylated-interferon (PEG-IFN)/ ribavirin therapy combined with vitamin D in elderly patients is unclear. OBJECTIVES This pilot study explored the efficacy and safety of alfacalcidol as vitamin D source in PEG-IFN/ ribavirin combination therapy for elderly CHC patients infected with hepatitis C virus genotype 1b. PATIENTS AND METHODS Consecutive twenty CHC patients aged ≥ 65 years were enrolled in this pilot study. Fifteen patients met the inclusion criteria and received PEG-IFN/ ribavirin therapy combined with alfacalcidol. Four-week lead-in of oral alfacalcidol was conducted, and it was subsequently and concurrently administered in PEG-IFN/ ribavirin combination therapy (vitamin D group). Age, gender, and IL28B genotype-matched patients, who received PEG-IFN/ ribavirin alone, were saved as control group (n = 15) to compare the treatment outcome with the vitamin D group. RESULTS Subjects consisted of 14 males and 16 females, with a median age of 70 years (65-78). The serum 25 (OH) D3 concentration in females (20 ng/ml, 11-37) was significantly lower than males (27 ng/mL, 13-49) (P = 0.004). Sustained virological response (SVR) rates were 33.3% (5/15) in the control group and 80.0% (12/15) in the vitamin D group, respectively (P = 0.025). While no significant difference was shown in the (SVR) rate between the two groups among males (P = 0.592), in females the SVR rate was significantly higher in the vitamin D group (87.5%, 7/8) than the control group (25.0%, 2/8) (P = 0.041). The relapse rates in the groups with and without alfacalcidol were 7.7% (1/13) and 61.5% (8/13), respectively (P = 0.011). Interestingly, in females, the relapse in the control group was shown in 5 of 7 (71.4%), whereas in the vitamin D group the relapse rate was decreased (1/8, 12.5%) (P = 0.041). No specific adverse events were observed in the vitamin D group. CONCLUSIONS PEG-IFN/ ribavirin combined with alfacalcidol may be effective and safe in elderly CHC patients. In particular, concomitant administration of alfacalcidol may lead to a reduced relapse rate, and consequently improving the SVR rate in elderly females.

Abstract
Alfa-fetoprotein (AFP) is used as a marker of early hepatocarcinogenesis. However, the impact of hepatitis B virus surface antigen (HBsAg) on this relationship in patients with HBV infection is not clear. The present study evaluated the relation between HBsAg and AFP levels at the initial visit in 1,610 untreated HBV patients, free of hepatocellular carcinoma (HCC) or severe hepatitis. The cumulative rate of HCC was significantly lower in patients with a low AFP level (≤10 µg/L; below the upper limit of normal) than in those with a high AFP level (≥11 µg/L) at the initial visit. In patients with HBsAg levels more than 500 IU/ml, HBsAg levels correlated significantly and negatively with AFP levels, and significantly with platelet count. Multivariate analysis of data of patients with HBsAg more than 500 IU/ml identified HBsAg (<7,000 IU/ml), albumin (<3.9 g/dl), platelet count (<20.0 × 10(4) /mm(3)), gamma-glutamyl transpeptidase (≥50 IU/L), aspartate aminotransferase (≥34 IU/L), HBeAg (positive), and HBV core-related antigen (≥3.0 log U/ml) as determinants of a high AFP. Especially, in patients with HBsAg more than 500 IU/ml and low transaminase levels (below the upper limit of normal), HBsAg was identified as significant determinant of a high AFP. On the other hand, in patients with HBsAg less than 500 IU/ml, multivariate analysis identified albumin, gamma-glutamyl transpeptidase, and HBV core-related antigen as determinants of a high AFP. The results indicated that HBsAg level seems to affect, at least in part, the AFP levels, and that it can be used as a surrogate marker of early hepatocarcinogenesis.

Abstract
OBJECTIVE Little is known about the relationship between elevated serum α-fetoprotein (AFP) levels and insulin resistance, which adversely influence the clinical course of chronic hepatitis C (CHC). Therefore, we investigated the association between serum AFP and insulin resistance in patients with CHC. METHODS We retrospectively investigated 300 patients with CHC without hepatoma who underwent liver biopsies and oral glucose tolerance tests. Patients taking antidiabetic drugs were excluded. We analyzed factors associated with elevated AFP levels (≥ 10.0 ng/mL) in 265 eligible patients. Twenty patients with a homeostasis model assessment for insulin resistance value of ≥ 2.0 and a whole-body insulin sensitivity index of <5.0 received prospective lifestyle intervention. RESULTS A univariate analysis showed that the body mass index, platelet count, levels of albumin, aspartate aminotransferase, alanine aminotransferase and γ-glutamyl transpeptidase, glucose metabolism, hepatic inflammation, fibrosis and steatosis were associated with elevated AFP levels. In a multivariate analysis, a platelet count of < 15 × 10(4) /μL, aspartate aminotransferase level of ≥ 50 IU/L, γ-glutamyl transpeptidase level of ≥ 35 IU/L, whole-body insulin sensitivity index of <5.0 and stage 3-4 fibrosis were independently associated with an elevated AFP level. A Bayesian Network analysis showed that the aspartate aminotransferase level, whole-body insulin sensitivity index and hepatic fibrosis were directly associated with an elevated AFP level. The lifestyle intervention significantly improved the serum AFP level, homeostasis model assessment for insulin resistance and whole-body insulin sensitivity index. CONCLUSION Whole-body insulin resistance is associated with an elevated serum AFP level in patients with CHC. Lifestyle interventions targeting insulin resistance can reduce the serum AFP level and may ameliorate the clinical course of CHC.

Abstract
BACKGROUND We investigated whether the administration of maintenance doses of interferon prevented hepatocellular carcinoma (HCC) in patients with chronic hepatitis C. METHODS Study 1: A multicenter, retrospective, cooperative study was carried out to determine whether long-term administration of low-dose peginterferon alpha-2a (PegIFNα-2a) prevented HCC development in patients with chronic hepatitis C. In total, 594 chronic hepatitis C patients without a history of HCC were enrolled and treated with 90 μg PegIFNα-2a administered weekly or bi-weekly for at least 1 year. Study 2: HCC developed in 16 of 99 additional patients without PegIFNα-2a treatment during 3.8 years of observation. A propensity-matched control study was then carried out to compare the incidence of HCC between the 59 patients who received low-dose PegIFNα-2a (PegIFNα-2a group) and 59 patients who did not receive PegIFNα-2a treatment (control group), matched for sex, age, platelet count, and total bilirubin levels. RESULTS Study 1: HCC developed in 49 patients. The risk of HCC was lower in patients with undetectable hepatitis C virus RNA, ≤40 IU/L alanine aminotransferase (ALT), or ≤10 ng/L alpha-fetoprotein (AFP) 24 weeks after the start of therapy. Study 2: The incidence of HCC was significantly lower in the PegIFNα-2a group than in the control group. CONCLUSIONS Low-dose and long-term maintenance administration of PegIFNα-2a decreased the incidence of HCC in patients with normalized ALT and AFP levels at 24 weeks compared with patients without normal ALT and AFP levels.

Abstract
OBJECTIVE Increasing evidence suggests the efficacy of maintenance therapy with interferon (IFN) for chronic hepatitis C (CHC) in reducing the risk of hepatocellular carcinoma (HCC). The aim of this study was to determine clinical characteristics on the risk of occurrence of HCC in CHC patients receiving maintenance IFN therapy. METHODS A total of 55 patients were treated in a single center with PEG-IFNα-2a monotherapy for CHC and evaluated for variables predictive of the occurrence of HCC. RESULTS The cumulative incidences of HCC were 0.092, 0.117 and 0.161 at 3, 5 and 7 years, respectively. Serum ALT level (>40 IU/l) in the 6th month after commencement of IFN therapy and BMI >25 were associated with shorter time-to-HCC emergence using multivariate analysis (relative risk 16.034, p = 0.01 for ALT >40 IU/l; relative risk 6.020, p = 0.026 for BMI >25, respectively). The IL28B SNP was extracted as a significant factor for the occurrence of HCC. CONCLUSIONS Maintenance therapy with the use of long-term low-dose PEG-IFNα-2a is effective for preventing HCC occurrence irrespective of the IL28B SNP, at least for a subset of CHC patients. The initial response of serum ALT levels and BMI provides a prognostic value for determining the risk of developing HCC later in life.

Abstract
Hepatitis C virus infection is a long-lasting disease, which causes chronic hepatitis, liver cirrhosis and hepatocellular carcinoma, thus leading to liver-related death. Currently, the optimal treatment for chronic hepatitis C infection is the combination of pegylated interferon and ribavirin. The aim of this review is to assess the long-term clinical outcomes of interferons alone or in combination with ribavirin in the management of chronic hepatitis C.

Abstract
BACKGROUND Increasing evidence suggests the efficacy of interferon therapy for hepatitis C in reducing the risk of hepatocellular carcinoma (HCC). The aim of this study was to identify predictive markers for the risk of HCC incidence in chronic hepatitis C patients receiving interferon therapy. METHODS A total of 382 patients were treated with standard interferon or pegylated interferon in combination with ribavirin for chronic hepatitis C in a single center and evaluated for variables predictive of HCC incidence. RESULTS Incidence rates of HCC after interferon therapy were 6.6% at 5 years and 13.4% at 8 years. Non-sustained virological response (non-SVR) to antiviral therapy was an independent predictor for incidence of HCC in the total study population. Among 197 non-SVR patients, independent predictive factors were an average alpha-fetoprotein (AFP) integration value ≥10 ng/mL and male gender. Even in patients whose AFP levels before interferon therapy were ≥10 ng/mL, reduction of average AFP integration value to <10 ng/mL by treatment was strongly associated with a reduced incidence of HCC. This was significant compared to patients with average AFP integration values of ≥10 ng/mL (P = 0.009). CONCLUSIONS Achieving sustained virological response (SVR) by interferon therapy reduces the incidence of HCC in hepatitis C patients treated with interferon. Among non-SVR patients, a decrease in the AFP integration value by interferon therapy closely correlates with reduced risk of HCC incidence after treatment.

Abstract
AIM The purpose of this clinical study was to determine the effect of a biweekly low-dosage peginterferon α-2a treatment program on serum alanine aminotransferase (ALT) and α-fetoprotein (AFP) levels. METHODS Fifty-five patients participated in the study. The inclusion criteria included chronic genotype 1b hepatitis C virus (HCV) infection, liver cirrhosis, or the absence of cirrhosis in subjects 65 years old or above, and interferon therapy naivety or a lack of sustained response to therapy with interferon-plus-ribavirin or peginterferon-plus-ribavirin. Patients were divided into naïve, relapser, and non-responder groups. The median age of the patients was 70 years, and 73% of patients had cirrhosis. All patients were treated with peginterferon α-2a at 90 µg biweekly. RESULTS The rates of normalization (≤30 IU/l) of ALT levels at week 24 in the relapser group and the ≥2 log(10) HCV RNA decline group were high (74% and 68%, respectively). However, the ALT and AFP levels decreased significantly in each group, including the non-responder group. The ALT levels decreased significantly even in patients in whom the HCV RNA levels did not decrease. Furthermore, the AFP levels decreased significantly in the patients showing no decline in the ALT and HCV RNA levels. Only three patients discontinued treatment within 48 weeks due to adverse events, and more than 70% of the patients experienced no subjective symptoms during treatment. CONCLUSION A biweekly low-dosage peginterferon α-2a therapy is effective for reducing the serum levels of ALT and AFP and may reduce hepatocarcinogenesis in patients with liver cirrhosis and in the elderly individuals.

Abstract
A 78-year-old male who experienced multiple recurrences of hepatocellular carcinoma (HCC) with hepatitis C virus (HCV)-related cirrhosis underwent transcatheter arterial chemoembolization and ablation and survived for more than 10 years. His serum HCV RNA level was 2.8 log IU/ml and the serotype of HCV was 2. He underwent long-term super-low-dose (20 μg/week) pegylated interferon-alpha 2b therapy to prevent recurrence of HCC. He became negative for HCV RNA 2 months later, and thereafter remained negative after the discontinuation of interferon therapy, and has not experienced a recurrence of HCC for more than 20 months.

Abstract
The consensus meeting for the diagnosis, management and treatment for hepatitis C was held in 45(th) annual meeting for the Japan Society of Hepatology (JSH) in June 2009 where the recommendations and informative statements were discussed including organizers and presenters. The Several important informative statements and recommendations have been shown. This was the fourth JSH consensus meeting of hepatitis C, however, the recommendations have not been published in English previously. Thus, this is the first report of JSH consensus of hepatitis C. The rate of development of hepatocellular carcinoma (HCC) in HCV-infected patients in Japan is higher than in the USA, because the average age of the HCV-infected patients is greater and there are more patients with severe fibrosis of the liver than in the USA. In Japan, more than 60% of HCV-infected patients are genotype 1b infection, and they show lower response to perinterferon and ribavirin combination treatment. To improve the response rate is also an important issue in our country. To establish the original recommendations and informative statements to prevent the development of HCC is a very important issue in Japan.

Abstract
INTRODUCTION The Asian Pacific Association for the Study of the Liver (APASL) convened an international working party on the management of hepatocellular carcinoma (HCC) in December 2008 to develop consensus recommendations.

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.

Abstract
This study was undertaken to investigate the effect of interferon (IFN) monotherapy on the risk of hepatocellular carcinoma (HCC) in aged-patients with chronic hepatitis C. Seven hundred and twenty-five patients with histologically proven chronic hepatitis C were enrolled in this retrospective cohort study; 531 received IFN monotherapy for 6 months between 1992 and 1995, and 157 were collected as a historical control. The effect of IFN therapy on the development of HCC was compared between the patients with chronic hepatitis C under 60 years old (non-aged group, n = 531) and those 60 and over (aged group, n = 194). A stepwise Cox proportional-hazards regression analysis in the non-aged group revealed that IFN therapy (risk ratio 0.52, 95% CI 0.33-0.81, P = 0.004), older age (P = 0.001), and higher histological stage (P < 0.001) were independent factors associated with the development of HCC. In the aged-group, only higher histological stage (P = 0.002) and male gender (P = 0.011), but not IFN therapy (risk ratio 0.77, 95% CI 0.42-1.40, P = 0.386), were identified as independent risk factors for HCC, although HCC was significantly reduced when sustained virological response (SVR) was obtained (risk ratio 0.23, 95% CI 0.08-0.64, P = 0.005). In conclusion, inhibitory effect of IFN on development of HCC in the patients with chronic hepatitis C aged 60 and over was limited to the patients achieving SVR when treated with 6 months-IFN monotherapy.

Abstract
BACKGROUND The impact of virologic response on hepatic function has not been previously defined. AIM To determine the relationships of quantitative liver function tests (QLFTs) with virological responses to peginterferon (PEG) +/- ribavirin (RBV) in patients with chronic hepatitis C and to use serial QLFTs to define the spectrum of hepatic improvement after sustained virological response (SVR). METHODS Participants (n = 232) were enrolled in the Hepatitis C Antiviral Long-term Treatment against Cirrhosis (HALT-C) Trial, had failed prior therapy, had bridging fibrosis or cirrhosis and were retreated with PEG/RBV. All 232 patients had baseline QLFTs; 24 patients with SVR and 68 nonresponders had serial QLFTs. Lidocaine, [24-(13)C]cholate, galactose and (99m)Tc-sulfur colloid were administered intravenously; [2,2,4,2-(2)H]cholate, [1-(13)C]methionine, caffeine and antipyrine were administered orally. Clearances (Cl), breath (13)CO(2), monoethylglycylxylidide (MEGX), perfused hepatic mass (PHM) and liver volume were measured. RESULTS Rates of SVR were 18-26% in patients with good function by QLFTs, but < or =6% in patients with poor function. Hepatic metabolism, measured by caffeine k(elim) (P = 0.02), antipyrine k(elim) (P = 0.05) and antipyrine Cl (P = 0.02) and the portal circulation, measured by cholate Cl(oral) (P = 0.0002) and cholate shunt (P = 0.0003) and PHM (P = 0.03) improved after SVR. CONCLUSION Hepatic dysfunction impairs the virological response to PEG/RBV. SVR improves hepatic metabolism, the portal circulation and PHM.

Abstract
As hepatitis B and C virus (HBV, HCV) play a pivotal role in the development of hepatocellular carcinoma (HCC), the prophylaxis and treatment of these infections may mean also the prevention of HCC. The primary prevention of HCC is vaccination against HBV as well as the screening of blood donors for HBV and HCV markers. The means of secondary HCC prevention are as follows: antiviral therapy of HBV and HCV-related hepatitis and cirrhosis, screening ("surveillance") of cirrhotic patients for HCC using alpha-fetoprotein and ultrasound, and adjuvant antiviral treatment of HCC patients following curative tumor resection/ablation. It may be anticipated that the world-wide spread of HBV vaccination, the more effective individual treatment and novel antivirals will lead to the decrease of HCC incidence in the not so distant future.

Abstract
BACKGROUND & AIMS Although the incidence of hepatocellular carcinoma (HCC) is increasing in the United States, data from large prospective studies are limited. We evaluated the Hepatitis C Antiviral Long-Term Treatment Against Cirrhosis (HALT-C) cohort for the incidence of HCC and associated risk factors. METHODS Hepatitis C virus-positive patients with bridging fibrosis or cirrhosis who did not respond to peginterferon and ribavirin were randomized to groups that were given maintenance peginterferon for 3.5 years or no treatment. HCC incidence was determined by Kaplan-Meier analysis, and baseline factors associated with HCC were analyzed by Cox regression. RESULTS 1,005 patients (mean age, 50.2 years; 71% male; 72% white race) were studied; 59% had bridging fibrosis, and 41% had cirrhosis. During a median follow-up of 4.6 years (maximum, 6.7 years), HCC developed in 48 patients (4.8%). The cumulative 5-year HCC incidence was similar for peginterferon-treated patients and controls, 5.4% vs 5.0%, respectively (P= .78), and was higher among patients with cirrhosis than those with bridging fibrosis, 7.0% vs 4.1%, respectively (P= .08). HCC developed in 8 (17%) patients whose serial biopsy specimens showed only fibrosis. A multivariate analysis model comprising older age, black race, lower platelet count, higher alkaline phosphatase, esophageal varices, and smoking was developed to predict the risk of HCC. CONCLUSIONS We found that maintenance peginterferon did not reduce the incidence of HCC in the HALT-C cohort. Baseline clinical and laboratory features predicted risk for HCC. Additional studies are required to confirm our finding of HCC in patients with chronic hepatitis C and bridging fibrosis.

Abstract
Previous studies identified amino acid (aa) substitutions of the hepatitis C virus core region of genotype 1b (HCV-1b core region) and elevated serum alpha-fetoprotein (AFP) levels as predictors of poor virologic response to pegylated interferon (PEG-IFN) plus ribavirin (RBV), and also as risk factors for hepatocarcinogenesis. The present study evaluated the impact of aa substitutions of HCV-1b core region on AFP, as a surrogate marker of hepatocarcinogenesis, on AFP levels in 569 Japanese patients with HCV-1b but without HCC, and investigated the predictive factors of elevated AFP (> or =11 microg/L). High AFP levels were detected in 27.4% of the patients. The rate of hepatocarcinogenesis in a group of 109 patients who received IFN monotherapy and followed-up for 15 years, was significantly higher in patients with abnormal than normal AFP. Multivariate analysis of 569 patients identified fibrosis stage (F3,4), aspartate aminotransferase (> or =76 IU/L), substitution of aa 70 (glutamine or histidine), and platelet count (<15.0 x 10(4)/microl) as significant determinants of elevated AFP. In 49 patients with abnormal AFP levels and substitutions at aa 70 who were treated with PEG-IFN + RBV, the rate of normalization of AFP was significantly lower in non-virological responders (28.6%) than in transient (71.4%) and sustained (100%) virological responders. The results indicated that substitution of aa 70 of HCV-1b core region is an important predictor of elevated AFP in non-HCC patients, and that eradication of the mutant virus normalizes AFP. The results highlight the importance of eradication of mutant type virus of aa 70 for reducing the risk of hepatocarcinogenesis.

Abstract
BACKGROUND Patients with chronic hepatitis C virus and advanced fibrosis or cirrhosis are at risk for disease progression and hepatic decompensation. AIM To determine the effects on hepatic histology of treatment with peginterferon alfa-2a (90 or 180 mug/week) or interferon alfa-2a (3 million units three times weekly) for 48 weeks in patients with paired biopsies. METHODS Liver biopsies were obtained at baseline and 6 months after end of treatment. Histological and virological responses were compared. RESULTS Patients attaining sustained virological response (n = 40) demonstrated the greatest improvements in fibrosis (-1.0, P < 0.0001) and inflammation (-0.65, P < 0.0001). Patients who cleared hepatitis C virus during treatment, but later relapsed (n = 59), experienced less improvement in fibrosis (-0.04, P < 0.0001) and inflammation (-0.14, P = 0.0768). Nonresponders (n = 85) showed no significant improvement in inflammation or fibrosis. Multiple regression analysis showed that the only factors contributing to improvement in fibrosis were sustained virological response (vs. nonresponder, P = 0.0005; vs. relapse, P = 0.7525) and body mass index < or =30 kg/m2 (P = 0.0995). CONCLUSIONS These findings indicate that virological response to peginterferon alfa-2a improves inflammation and fibrosis in hepatitis C virus patients with advanced fibrosis or cirrhosis. Improving virological response and maintaining ideal body weight are critical for achieving optimal histological outcomes in hepatitis C virus patients.
