Introduction: We evaluated the efficacy and safety of lenvatinib-transcatheter arterial chemoembolization (LEN-TACE) sequential therapy for patients (n = 88) with intermediate-stage hepatocellular carcinoma (HCC). Methods: Eighty-eight patients who obtained tumor control by LEN treatment were analyzed; 30 received LEN followed by TACE (LEN-TACE sequential therapy), and 58 received LEN monotherapy. Propensity score matching was performed, and the outcomes of 19 patients in the LEN-TACE group and 19 patients in the LEN-alone group were compared. Objective response rate (ORR), progression-free survival (PFS), overall survival (OS), incidence of adverse events (AEs), and change in albumin-bilirubin (ALBI) score were evaluated. Results: After matching, baseline characteristics were similar between the groups. The ORR was 63.2% with LEN-TACE group and 63.2% with the LEN-alone group. Multivariate analysis showed that addition of TACE during LEN treatment (hazard ratio [HR] 0.264, 95% confidence interval [CI] 0.087–0.802, p = 0.019) and Child-Pugh score 5 (HR 0.223, 95% CI 0.070–0.704, p = 0.011) were the significant factors for PFS. Median PFS was 11.6 months with LEN-TACE and 10.1 months with LEN-alone. The survival rate of the LEN-TACE group was significantly higher than that of the LEN-alone group (median survival time; not reached vs. 16.9 months, p = 0.007). The incidence of common LEN-associated AEs was similar between groups. Although elevated aspartate aminotransferase/alanine aminotransferase and fever were more frequent with LEN-TACE group, these events were manageable. Conclusion: For patients with intermediate-stage HCC, LEN-TACE sequential therapy may provide a deep response and favorable prognosis.

The study aimed to investigate the efficacy of vonoprazan 10 mg compared with 20 mg in patients with erosive esophagitis. Seventy-three patients with erosive esophagitis were randomly divided into two groups either vonoprazan 20 mg (n = 37) or 10 mg (n = 36). They were administered each dose for 4 weeks as the initial treatment followed by maintenance treatment with 10 mg for 8 weeks. The primary endpoints were mucosal healing rate and symptom relief at 4 weeks. The secondary endpoint was symptom relief at 12 weeks after the maintenance treatment. Mucosal healing was assessed endoscopically, and symptom relief was assessed using the FSSG score. At 4 weeks, the endoscopic healing rates of the 20 mg and 10 mg groups were 94.6% and 94.4%, respectively. The FSSG scores of the 20 mg and 10 mg groups were significantly decreased in both treatment groups from 13 (4–39) to 4 (0–25) and 14 (4–40) to 3 (0–29), respectively. At 12 weeks, the scores further decreased to 2 (0–13) and 2 (0–26), respectively. The vonoprazan 10 mg group showed a similar therapeutic effect to the 20 mg group in mucosal healing at 4 weeks and in symptom relief throughout the study period. When stratified by esophagitis grading, these findings were still demonstrated in grade A/B patients but not in grade C/D patients. Our findings suggest that initial treatment with vonoprazan 10 mg might be useful especially in patients with mild erosive esophagitis. Large controlled studies are warranted to confirm our investigation.

The hepatitis C virus (HCV) NS5A-P32 deletion (P32del) confers potent resistance to NS5A inhibitors. Chronic hepatitis C patients in whom NS5A-P32del variants had emerged during prior direct-acting antiviral (DAA) therapy with an NS5A inhibitor show poor response to DAA retreatment. Here, we report three patients with HCV NS5A-P32del infection who were treated with sofosbuvir, velpatasvir plus ribavirin (SOF/VEL + RBV) in a real-world setting. The patients developed HCV NS5A-P32del, L31F + P32del, or L31V + P32del variants following failure of daclatasvir plus asunaprevir (DCV/ASV) therapy. One of the patients failed to respond to subsequent DCV/ASV and beclabuvir therapy, and the remaining two patients failed to respond to subsequent glecaprevir and pibrentasvir therapy. All three patients completed 24-week SOF/VEL + RBV therapy. Serum HCV RNA became negative at the end of the therapy in all three patients. Two patients with NS5A-P32del and NS5A-L31F + P32del achieved sustained virological response 12 weeks after completion of treatment (SVR12), but HCV relapsed in the remaining NS5A-L13V + P32del patient. Direct sequence analysis detected no additional variants within either the NS5A or NS5B regions at the time of relapse. In conclusion, three patients with prior NS5A-P32del-associated DAA treatment failure received 24 weeks of SOF/VEL + RBV therapy, and two of the patients achieved SVR12.

Atezolizumab is an immune checkpoint inhibitor that is a key drug in non-small-cell lung cancer treatment. However, it can cause immune-related adverse events, including liver injury. Several patterns of liver injury associated with immune checkpoint inhibitor therapy have been reported; however, not much is known about sclerosing cholangitis. We present here a case of lung adenocarcinoma with atezolizumab-induced secondary sclerosing cholangitis diagnosed using needle biopsy of the liver. A 77-year-old woman with lung adenocarcinoma, cT3N2M0, stage IIIA, was treated with concurrent chemoradiotherapy involving carboplatin and paclitaxel, which markedly reduced the tumor diameter. However, 5 months later, the lesion regrew, and she underwent 39 cycles of pemetrexed monotherapy. As pulmonary metastasis progressed, she was treated with atezolizumab. After 13 cycles of atezolizumab therapy, she complained of nausea. Laboratory tests showed elevated levels of the biliary tract and hepatic enzymes. Nevertheless, abdominal computed tomography and ultrasonography revealed no underlying related cause. Ultrasound-guided needle biopsy of the liver was performed, and histopathological analysis of biopsy samples showed features of sclerosing cholangitis. Further examinations were performed, and a diagnosis of atezolizumab-induced secondary sclerosing cholangitis without strictures and dilatations of the large bile ducts was established. Prednisolone was administered orally, after which the biliary tract and hepatic enzyme levels improved immediately. In patients presenting with a hepatic injury during immune checkpoint inhibitor therapy, clinicians should be aware of the possibility of immune checkpoint inhibitor-induced sclerosing cholangitis, even if the large bile ducts have no strictures and dilatations.

Background: Although a strong antitumor effect of lenvatinib (LEN) has been noted for patients with unresectable hepatocellular carcinoma (HCC), there are still no reports on the prognosis for patients with disease progression after first-line LEN therapy. Methods: Patients (n = 141) with unresectable HCC, Child-Pugh class A liver function, and an Eastern Cooperative Oncology Group performance status (ECOG-PS) of 0 or 1 who were treated with LEN from March 2018 to December 2019 were enrolled. Results: One hundred and five patients were treated with LEN as first-line therapy, 53 of whom had progressive disease (PD) at the radiological evaluation. Among the 53 patients with PD, there were 27 candidates for second-line therapy, who had Child-Pugh class A liver function and an ECOG-PS of 0 or 1 at progression. After progression on first-line LEN, 28 patients were treated with a molecular targeted agent (MTA) as second-line therapy (sorafenib: n = 26; ramucirumab: n = 2). Multivariate analysis identified modified albumin-bilirubin grade 1 or 2a at LEN initiation (odds ratio 5.18, 95% confidence interval [CI] 1.465–18.31, p = 0.011) as a significant and independent factor for candidates. The median post-progression survival after PD on first-line LEN was 8.3 months. Cox hazard multivariate analysis showed that a low alpha-fetoprotein level (p = 0.003), a relative tumor volume p = 0.03), and switching to MTAs as second-line treatment after LEN (HR 0.299, 95% CI 0.12–0.746, p = 0.01) were significant prognostic factors. Conclusion: Among patients with PD on first-line LEN, good liver function at introduction of LEN was an important and favorable factor related to eligibility for second-line therapy. In addition, post-progression treatment with MTAs could improve the prognosis for patients who had been treated with first-line LEN.

AIM Combination therapy with sofosbuvir (SOF) plus velpatasvir (VEL) is approved for patients with hepatitis C virus (HCV)-related decompensated cirrhosis. We analyzed the real-world efficacy of SOF/VEL therapy. METHODS Thirty-three patients with HCV-related decompensated cirrhosis (25 and eight patients with Child B and C, respectively) were treated with SOF/VEL for 12 weeks. The HCV non-structural protein (NS)5A and NS5B drug resistance-associated substitutions (RASs) were determined by direct sequencing. RESULT Thirty-two of 33 patients completed the treatment, but the remaining patient discontinued the therapy during third week of the treatment due to aggravation of hepatic encephalopathy. Serum HCV-RNA became negative during the treatment in all patients but relapsed after the end of therapy in five patients. In total, 28 out of 33 patients (85%) achieved sustained virological response 12 weeks following completion of treatment (SVR12). The SVR12 rate was 96% in patients with Child B, but significantly lower, at 50%, in patients with Child C (P

Background and aim Sorafenib is the standard treatment for patients with advanced hepatocellular carcinoma (HCC) with distant metastasis, unresectable HCC, and HCC refractory to transcatheter arterial chemoembolization (TACE) or with macroscopic vascular invasion (MVI). Also, hepatic arterial infusion chemotherapy (HAIC) has been used for advanced HCC in Southeast and East Asian countries. However, clearer information is needed for choosing appropriately between these therapies. Methods The subjects were 391 HAIC and 431 sorafenibs administered at our hospital and related hospitals. In this case, cases that satisfy the following three conditions were targeted: (i) no extrahepatic metastasis, (ii) Child-Pugh A, and (ii) not having received treatment of both HAIC and sorafenib during the course. As a result, 150 cases of HAIC and 134 cases of sorafenib were analyzed this time. Results Univariate and multivariate analyses were performed for the HAIC and sorafenib groups. TACE refractory status and MVI were factors contributing to overall survival (OS). Therefore, this study divided all cases according to those variables. The median survival time of MVI-positive and non-TACE refractory cases was significantly better with HAIC (13 months) versus sorafenib (6 months). However, in MVI-negative and TACE refractory cases, the median survival time of HAIC (8 months) was significantly poorer than for sorafenib (20 months). Conclusion Transcatheter arterial chemoembolization refractory status with HAIC and MVI with sorafenib were factors for poor prognosis. In particular, HAIC was significantly better than sorafenib as primary treatment in MVI and non-TACE refractory cases. It is necessary to consider these factors in treatment selection.

Objective: To compare the outcome of hepatic arterial infusion chemotherapy combined with radiotherapy (HAIC + RT) versus sorafenib monotherapy in patients with advanced hepatocellular carcinoma (HCC) and major portal vein tumor thrombosis (PVTT). Methods: This retrospective study included 108 HCC patients with PVTT of the main trunk or first branch and Child-Pugh ≤7. Sixty-eight received HAIC + RT and 40 received sorafenib. Patients were then assigned to the HAIC + RT group (n = 36) and the sorafenib group (n = 36) through case-control matching. The decision to treat with HAIC + RT or sorafenib was left to the attending physician. Results: The median overall, progression-free, and postprogression survival were significantly longer in the HAIC + RT group than in the sorafenib group (9.9 vs. 5.3, p = 0.002; 3.9 vs. 2.1, p = 0.048; and 3.7 vs. 1.9 months, p = 0.02, respectively). Multivariate analysis identified HAIC + RT (hazard ratio = 2.02; 95% confidence interval, 1.14–3.57; p = 0.01) as a significant and independent determinant of overall survival. Conclusions: In patients with advanced HCC and major PVTT, survival was significantly longer in those treated with HAIC + RT than with sorafenib.

Background and Aims Daclatasvir and asunaprevir combination therapy has shown a high virological response for chronic genotype 1 hepatitis C virus (HCV) infected-patients. However, the real-world efficacy and safety of the therapy for patients with cirrhosis are unknown. Methods A total of 252 patients with genotype 1 HCV infection (158 with chronic hepatitis and 94 with compensated liver cirrhosis) were treated with 24 weeks of daclatasvir and asunaprevir combination therapy. Plasma concentrations of daclatasvir and asunaprevir at day 5 of treatment, end-of-treatment response, sustained virological response (SVR), and the frequencies of adverse events were analyzed. Result Plasma asunaprevir concentration was significantly higher, and daclatasvir concentration tended to be higher, in cirrhosis patients compared with chronic hepatitis patients. End-of-treatment response was achieved in 95.6% and 94.7% of chronic hepatitis and cirrhosis patients, respectively, and SVR was achieved in 94.3% and 92.6%. Although pre-treatment NS5A drug resistant-associated variants were detected, a high SVR rate was achieved when the population frequency of the variant was low. The frequencies of treatment-related adverse events in cirrhosis patients were similar to those in chronic hepatitis patients. Treatment discontinuation due to adverse events occurred in three and two patients in chronic hepatitis and cirrhosis groups, respectively; however, four out of five patients with treatment discontinuation nonetheless achieved SVR. Conclusion Patients with compensated liver cirrhosis have similar virological response and tolerance for daclatasvir plus asunaprevir therapy to patients with chronic hepatitis. This combination therapy might offer a safe and effective treatment for chronic HCV infected-patients with compensated cirrhosis.

Although sorafenib is the standard treatment for patients with advanced hepatocellular carcinoma (HCC), the predictive factors sorafenib tolerance in intermediate-stage HCC cannot be accurately determined. The aim of the current study was to identify the predictive characteristics for the continuation of sorafenib treatment (≥400 mg) in patients with transarterial chemoembolization (TACE)-refractory intermediate HCC and to identify candidates for second-line sorafenib treatment. A total of 33 TACE-refractory intermediate patients with HCC that were treated with sorafenib, and who had reached progressive disease (PD), were analyzed in the present retrospective study. Of 33 patients, 6 patients (18.1%) were able to continue sorafenib treatment (≥400 mg) until PD, however, a total of 27 patients (71.9%) were unable to continue treatment (180 mg/dl; P=0.026) and cholinesterase (ChE; ≥220 U/l; P=0.024) were significant factors, and a multivariate analysis indicated that ChE (≥220 U/l) was a significant prognostic factor (HR: 11.9; 95% CI: 1.19–118.0; P=0.004). Both progression-free survival [279 (204–403) vs. 117.5 (63–197) days; P=0.0136] and OS [470 (277–679) vs. 171.5 (80–236) days; P=0.0004] were significantly increased in patients with ChE levels ≥220 U/l compared with patients exhibiting ChE levels

Background Elbasvir (EBR) in combination with grazoprevir (GZR) has demonstrated efficacy in patients with hepatitis C virus (HCV) infections in trials primarily conducted in the USA and Europe. We investigated the safety and efficacy of EBR in combination with GZR in Japanese patients with chronic HCV infection, with or without cirrhosis. Methods The study was conducted in two parts. In part 1, noncirrhotic patients were randomized 1:1 to receive EBR (50 mg) in combination with GZR (50 or 100 mg) once daily for 12 weeks. In part 2, noncirrhotic patients were randomized 3:1 to receive immediate or deferred treatment with EBR (50 mg) and GZR (100 mg, determined in part 1) for 12 weeks; cirrhotic patients received open-label immediate treatment. The primary efficacy end point was the rate of sustained virologic response 12 weeks after completion of the study treatment. Results In part 1, 63 patients were randomized to receive EBR in combination with GZR at a dose of 50 mg (n = 31) or 100 mg (n = 32). The SVR12 rates were 100% with GZR at a dose of 50 mg and 96.8% with GZR at a dose of 100 mg. Tolerability was similar in both arms. In part 2, 301 noncirrhotic patients were randomized to receive immediate treatment (n = 227) or deferred treatment (n = 74), and 35 cirrhotic patients were enrolled. The SVR12 rates were 96.5% and 97.1% after immediate treatment in noncirrhotic and cirrhotic patients respectively. Safety was generally similar between immediate and deferred treatment. Conclusion Treatment with EBR in combination with GZR for 12 weeks is effective and well tolerated in Japanese patients with chronic HCV infection. ClinicalTrials.gov identifier NCT02203149.

Aim Older patients with chronic hepatitis C have a lower virological response to interferon (IFN)-based treatments compared to younger patients. A single nucleotide polymorphism in the IFN-λ-4 (IFNL4) gene has a potent predictive effect on treatment response to IFN-based treatments. The efficacy of simeprevir (SMV) plus pegylated-IFN (PEG-IFN) and ribavirin therapy and the predictive value of IFNL4 on the outcome of therapy for older patients have not been addressed. Methods This retrospective multicenter study included 234 consecutive Japanese patients with genotype 1 chronic hepatitis C. We assessed the predictive factors for sustained virological response (SVR) to SMV, PEG-IFN, and ribavirin triple therapy in 170 younger (

The aim of this study was to compare the outcome of patients with hepatocellular carcinoma (HCC), Barcelona Clinic Liver Cancer (BCLC) stages 0 and A, and portal hypertension (PHT) who underwent liver resection (LR) or radiofrequency ablation (RFA). The study population consisted of 121 patients with PHT and HCC of BCLC stage 0 and A who underwent LR (n = 81) or RFA (n = 40). To reduce bias in patient selection, the different covariate distributions in two groups were adjusted using inverse probability treatment weighting (IPTW). The prognostic outcomes of LR- and RFA-treated patients were then analyzed. Before IPTW adjustment, the 5-year overall survival (OS) of LR and RFA patients was comparable. Five-year recurrence-free survival (RFS) was significantly better in the LR group than in the RFA group (P

The virological efficacy and safety of the direct-acting antiviral (DAA) regimen consisting of daclatasvir, asunaprevir, and beclabuvir (DCV/ASV/BCV) for patients chronically infected with hepatitis C virus (HCV) genotype 1 have not been previously evaluated in Japanese real-world settings. In a Japanese nationwide multicenter study, the rate of sustained virologic response (SVR) and safety were analyzed in 91 patients who started the DCV/ASV/BCV regimen between November 2016 and July 2017. SVR rates were compared based on baseline patient characteristics. More than 60% of patients had a history of failure to achieve SVR with interferon (IFN)-free DAA therapy. Overall, 50 of 91 patients (54.9%) achieved SVR. Multivariate analysis identified a history of failure with IFN-free DAA therapy and pretreatment HCV RNA levels as factors significantly associated with treatment failure. Whereas the SVR rate in patients without a history of IFN-free DAA therapy was 91.7% (33 of 36 patients), it was only 30.9% (17 of 55 patients) among patients with a history of IFN-free DAA therapy. The rate of discontinuation due to an adverse event was 4.4%. Many patients treated with the DCV/ASV/BCV regimen have a history of a failure to achieve SVR with previous IFN-free DAA therapy. SVR rate was not as high as that in pre-approval clinical trial of this regimen in IFN-free DAA-naive patients. In addition, most patients with a history of failure with IFN-free DAA therapy, particularly the DCV/ASV regimen, showed resistance to this regimen.

We aimed to describe the real-world efficacy and safety of combination therapy with ledipasvir and sofosbuvir (LDV/SOF) for chronic hepatitis C virus (HCV) genotype 1 (GT1) infection. This retrospective analysis of a prospective, nationwide, multicenter registry included GT1-infected patients treated with LDV/SOF for 12 weeks. We assessed the rate of sustained virological response at 12 weeks post-treatment (SVR12), incidence of adverse events, and serum markers of hepatocellular carcinoma (HCC). Among the 1461 patients included (mean age, 69 years; 29.5% aged > 75 years; cirrhosis, 23.8%; history of treatment for HCC, 10.9%), the overall SVR12 rate was 98.4% (1438/1461). Factors associated with treatment failure were cirrhosis (odds ratio, 4.19; p = 0.014) and resistance-associated substitutions (RASs) in NS5A at baseline (odds ratio, 7.78; p = 0.0004). The SVR12 rate in patients with cirrhosis and NS5A RASs was 93.0% compared to 100% in patients without cirrhosis or NS5A RASs. In patients with SVR, the levels of alpha-fetoprotein (AFP), AFP-L3, and Mac-2 binding protein glycosylation isomer (M2BPGi) decreased from baseline to end of treatment (from 13.4 ± 37.6 to 6.0 ± 10.6 ng/mL, p

In Japan, daclatasvir (DCV) and asunaprevir (ASV) therapy was the first IFN-free treatment to be approved, and thousands of patients have since been successfully treated, with an SVR rate of around 90%. The converse, however, is that around 10% of patients fail to achieve viral eradication and must be retreated using a different approach. This study is to evaluate treatment efficacy of ledipasvir/sofosbuvir and ribavirin in patients who failed to respond to DCV and ASV therapy. Thirty patients were treated with 12 weeks of ledipasvir/sofosbuvir and ribavirin. We evaluated the rate of sustained virological response 12 weeks after the end of treatment (SVR12) and examined the incidence of adverse events during ledipasvir/sofosbuvir and ribavirin treatment. NS5A and NS5B resistance-associated variants (RAVs) in treatment failure cases were examined. The overall SVR12 rate was 86.7% (26/30). Large decreases in mean log10 HCV RNA levels were observed in patients without cirrhosis, and the SVR12 rate for these patients was 100% (12/12). In cases of cirrhosis, SVR12 rate was 72.2% (13/18). The common factors in treatment failure cases were the presence of liver cirrhosis and both NS5A L31M/I and Y93H RAVs. The frequency of RAVs did not change before and after treatment among patients who relapsed. Ledipasvir/sofosbuvir with ribavirin is an effective retreatment option for patients with chronic hepatitis C who failed to respond to prior daclatasvir and asunaprevir therapy.

Aim Acoustic radiation force impulse (ARFI) technology, involving the shear wave velocity (SWV) with virtual touch tissue quantification (VTTQ), are currently available for the assessment of liver fibrosis, while there is no index derived from the combination of SWV and blood tests. The aim of this study was to develop a new index for assessment of liver fibrosis. Methods The subjects were 176 consecutive patients with hepatitis C (training set [n = 120] and validation set [n = 56]) who underwent liver biopsy in our institution. Results In the training set, SWV, international normalized ratio (INR) and alanine aminotransferase (ALT) correlated independently and significantly with fibrosis. According to this, we developed the VIA index = −1.282 + 0.965 × SWV + 1.785 INR + 0.00185 ALT. The areas under the receiver–operator curve (AUROC) of the VIA index were 0.838 for the diagnosis of significant fibrosis (≥F2), 0.904 for the severe fibrosis (≥F3) and 0.958 for the cirrhosis (F4) in the training set. While in the validation set, AUROC of the VIA index were 0.917 for F2 or higher, 0.906 for F3 or higher and 1.000 for F4, respectively. AUROC of the VIA index was improved compared to SWV alone, equivalent for VIA for the diagnosis of F2 or higher, and superior to that of FIB-4 index and aspartate aminotransferase-to-platelet ratio index for the diagnosis of F3 or higher and F4. Conclusion The VIA index is potentially more useful for assessment of liver fibrosis than SWV alone, and easily and accurately measures liver fibrosis stage.

Aim Steatosis is a common histological feature of chronic liver disease, especially alcoholic and non-alcoholic fatty liver disease, as well as chronic hepatitis C. A recent study showed that evaluating the controlled attenuation parameter (CAP) with transient elastography was an efficient way of non-invasively determining the severity of hepatic steatosis. The objective of this study was to prospectively evaluate the utility of CAP for diagnosing steatosis in patients with chronic liver disease. Methods One hundred and fifty-five consecutive patients with suspected chronic liver disease underwent steatosis diagnosis using CAP, blood sample analyses, computed tomography for assessing the liver/spleen ratio and liver biopsy. Steatosis was graded according to the percentage of fat-containing hepatocytes: S0, less than 5%; S1, 5–33%; S2, 34–66%; and S3: more than 66%. Results The CAP was significantly correlated with steatosis grade, and there were significant differences between the CAP value of the S0 patients and those of the patients with other grades of steatosis. S0 and S1–3 hepatic steatosis were considered to represent mild and significant steatosis, respectively. The CAP values of the patients with mild and significant steatosis were significantly different (P

AbstactBackground and Aims To compare the tumor control and safety of stereotactic body radiation therapy (SBRT) combined with transcatheter arterial chemoembolization (TACE) for small, solitary, and hypervascular hepatocellular carcinoma (HCC) with TACE alone. Methods Three hundred and sixty-five HCC patients who had solitary, ≤ 3 cm, and hypervascular nodule were treated with TACE. Among them, 30 patients followed by SBRT (SBRT group) and 38 patients without additional therapy and previous HCC treatment (control group) were enrolled in this retrospective cohort study. Local tumor progression, complication, and disease-free survival were compared between these groups. Results There was no difference in clinical background between these groups. Complete response to therapy was noted in 29 (96.3%) patients of the SBRT group, and in only one (3.3%) patient of the TACE group (P

Daclatasvir and asunaprevir combination therapy has shown a high virological response for chronic genotype 1 hepatitis C virus (HCV)-infected patients. However, the safety and efficacy of the therapy for older patients are unknown. One hundred seventy patients younger than 75 years and 139 patients aged 75 years or older with genotype 1 HCV infection were treated for 24 weeks with daclatasvir plus asunaprevir. Pretreatment drug-resistance-associated variants at NS5A-L31 and NS5A-Y93 were determined by the Invader assay. Virological response and adverse events according to age were analyzed. The sustained virological response (SVR) rate for older patients was similar to that for younger patients (97.1 and 92.4 % respectively). In multivariate regression analysis, prior simeprevir treatment (odds ratio 56.6 for absence; P

Background and Aim We compared the treatment response, survival, and safety to hepatic arterial infusion chemotherapy (HAIC) in patients with advanced hepatocellular carcinoma (HCC) according to Child–Pugh (CP) score. Methods The study subjects were 249 patients with advanced HCC and CP class A and B who had been treated with HAIC. Patients were grouped according to CP score (5/6, 7 and 8/9) and their tumor response, tolerance, and survival were assessed. Results The median survival time (MST) was 8.2, 9.7, 6.3, and 3.9 months for the whole group, patients with CP 5/6, 7 and 8/9, respectively (P

Background and Aim: Interleukin-28B (IL28B) single nucleotide polymorphism (SNP) influences viral response (VR) to interferon (IFN) therapy in patients with hepatitis C. We studied the relationship between VR and the IL28B polymorphism (rs8099917) in patients on long-term pegylated IFN plus ribavirin (PEGIFN/RBV) therapy for recurrent hepatitis C after living-donor liver transplantation (LDLT). Methods: Thirty-five patients with recurrent hepatitis C after LDLT were treated with PEGIFN/RBV. We evaluated the effect of IL28B SNP on the outcome in 20 patients infected with hepatitis C virus genotype 1 who completed IFN therapy. Results: The sustained VR (SVR) rate was 54% (19/35) for all patients; 46% (13/28) for genotype 1. The SVR rate of donors' TT group (major genotype) was higher than that of donors' TG + GG group (minor genotype) (73% vs 20%), while that of recipients' TT group was similar to that of recipients' TG + GG group (64% vs 50%). With regard to the combined effect of donors' and recipients' IL28B SNP, the SVR rates of TT : TT (donors' : recipients'), TT : TG + GG, TG + GG : any group were 81%, 50%, and 20%, respectively. The VR rate of TT : TT, TT : TG + GG and TG + GG : any group at 12 weeks were 28%, 0%, and 0%; those at 48 weeks were 70%, 50%, 20%, and those at the end of treatment were 100%, 50%, 20%, respectively. The multivariate analysis identified IL28B of donors : recipients (TT : TT) as the only independent determinant of SVR (odds ratio 15.0, P = 0.035). Conclusion: Measurement of donors' and recipients' IL28B SNP can predict the response to PEGIFN/RBV therapy, and the donors' IL28B SNP might be a more significant predictor than that of the recipients.

We report a case in which sustained viral response was achieved after switching treatment from pegylated interferon (PEG-IFN) α-2b to α-2a and ribavirin (RBV) in patients with recurrence of hepatitis C virus (HCV) infection after living donor liver transplantation. The patient was a 62-year-old man with liver cirrhosis due to HCV genotype 1b infection. The patient had 8 amino acid (aa) substitutions in the interferon sensitivity-determining region, and had substitutions for mutant and wild-type at aa70 and aa91, respectively, in the core region. The patient had minor genotype (GG) IL28B single nucleotide polymorphisms (rs8099917). He had initially received interferon α-2b and RBV for 2 years, and later developed hepatocellular carcinoma (HCC). After surgical resection of HCC, he subsequently received PEG-IFN α-2b and RBV for 1.5 years, without undetectable viremia during the treatment course. Due to recurrence of HCC, the patient received a living donor liver transplantation. Later on, hepatitis C relapsed. For the management of relapse, he received another course of PEG-IFN α-2b and RBV. However, breakthrough viremia occurred. PEG-IFN was thus switched from α-2b to α-2a and RBV for another 17 months. The patient eventually achieved a sustained viral response.

Aim: We investigated the efficacy of hepatic arterial infusion chemotherapy (HAIC) using 5-fluorouracil (5-FU) and systemic interferon (IFN)-α (HAIC-5-FU/IFN) for advanced hepatocellular carcinoma (HCC) with venous tumor thrombosis (VTT) in the hepatic vein trunk (Vv2) or inferior vena cava (Vv3). Methods: Thirty-three patients with HCC/Vv2/3 underwent HAIC with 5-FU (500 mg/body weight/day, into hepatic artery on days 1–5 on the first and second weeks) and IFN-α (recombinant IFN-α-2b 3 000 000 U or natural IFN-α 5 000 000 U, intramuscularly on days 1, 3 and 5 of each week). Three-dimensional conformal radiotherapy (3D-CRT) was used in combination with HAIC-5-FU/IFN in 14 of 33 patients to reduce VTT. Result: The median survival time (MST) was 7.9 months, and 1- and 2-year survival rates were 30% and 20%, respectively. Evaluation of intrahepatic response after two cycles of HAIC-5-FU/IFN showed complete response (CR) in three (9%) and partial response (PR) in seven (21%), with an objective response rate of 30%. Multivariate analysis identified reduction of VTT (P = 0.0006), size of largest tumor (P = 0.013) and intrahepatic response CR/PR (P = 0.030) as determinants of survival. CR/PR correlated significantly with tumor liver occupying rate (P = 0.016) and hepatitis C virus Ab (P = 0.010). Reduction of VTT correlated significantly with radiotherapy (P = 0.021) and platelet count (P = 0.015). Radiotherapy-related reduction in VTT significantly improved survival of 16 patients with Vv3 and non-CR/PR response of HAIC-5-FU/IFN (P = 0.028). Conclusion: As for advanced HCC with VTT of Vv2/3, HAIC-5-FU/IFN responsive patients could obtain favorable survival. Despite ineffective HAIC-5-FU/IFN, the combination with effective radiotherapy to VTT might improve patients' prognosis.

Aim: In this study, we evaluated the clinical characteristics of hepatocellular carcinoma (HCC) because the etiology of HCC has been changing recently. Methods: Consecutive 1374 HCC patients at our institution from 1995 to 2009 were enrolled and clinical characteristics were investigated. Results: Seventeen percent and 67% of HCC were related to hepatitis B virus (HBV-HCC) and hepatitis C virus (HCV-HCC), respectively. Fifteen percent of that was negative for hepatitis B surface antigen (HBsAg) and antibody to hepatitis C virus (HCVAb) (NBNC-HCC). HCV-HCC tended to decrease and NBNC-HCC tended to increase in recent years. Patients with NBNC-HCC and HCV-HCC were significantly older than those with HBV-HCC. The complication rates of diabetes mellitus (DM), heavy alcohol consumption, hypertension, and hyperlipidemia in NBNC-HCC were significantly higher than those in other groups. Furthermore, the platelet counts and body mass index in NBNC-HCC were significantly higher than those of other groups. Among 209 NBNC-HCC patients, 58 patients underwent hepatic resection in which 29%, 36%, and 35% of those were based on non-alcoholic steatohepatitis (NASH), heavy alcohol consumption, and unknown etiology, respectively. DM was prevalent especially in NASH and heavy alcohol consumption. Cirrhosis was detected in 65%, 81%, and 15% in NASH-HCC, heavy alcohol consumption-HCC, and unknown etiology, respectively. Conclusions: NBNC-HCC has gradually been increasing in recent years. The present study elucidated that the presence of NASH and metabolic syndrome were important risk factors for NBNC-HCC and suggests that these patients should receive surveillance for HCC development.

Aim: To analyze the clinical outcome of esophageal varices (EV) after hepatic arterial infusion chemotherapy (HAIC) in patients with advanced hepatocellular carcinoma (HCC) and major portal vein tumor thrombus (Vp3/4). Methods: The study subjects were 45 consecutive patients who received HAIC for HCC with Vp3/4 between January 2005 and December 2009. HAIC comprised the combination therapy of intra-arterial 5-FU with interferon-α (5-FU/IFN) in 23 patients and low-dose cisplatin plus 5-FU (FP) in 22. Radiotherapy (RT) was also provided in 19 patients for portal vein tumor thrombosis. Aggravation rate for EV and overall survival rate were analyzed. Results: The aggravation rates for EV were 47% and 64% at 12 and 24 months, respectively. The survival rates were 47% and 33% at 12 and 24 months, respectively. The response rates to 5-FU/IFN and FP were 35% and 41%, while the disease control rates in these two groups were 57% and 50%, respectively. There were no significant differences in the objective response and disease control between 5-FU/IFN and FP. Multivariate analysis identified size of EV (F2/F3) (HR = 7.554, P = 0.006) and HCC disease control (HR = 5.948, P = 0.015) as significant and independent determinants of aggravation of EV, and HCC disease control (HR = 12.233, P

Summary. The present study was designed to determine the predictive factors for the viral response to pegylated interferon-alpha plus ribavirin combination therapy (PEGIFN/RBV) administered after curative treatment for hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC). The study group was 78 patients treated between January 2005 and January 2009. The sustained viral response (SVR) rate was 25.8% (15/58) in patients infected with HCV-genotype 1 and 55.0% (11/20) in those with genotype 2. Among the 78 patients, 32 (41.0%) could not complete the treatment protocol, and this was because of HCC recurrence in 17 (53%) of them. Multivariate analysis identified partial early viral response (pEVR) as the only independent determinant of SVR [odds ratio (OR) 14.73, P = 0.013] for patients with genotype 1. Multivariate analysis identified male gender (OR 8.72, P = 0.001) and interleukin-28B (IL-28B) genotype (rs8099917) TT (OR 7.93, P = 0.007) as independent predictors of pEVR. Multivariate analysis also identified IL-28B genotype GG+TG (OR 14.1, P = 0.021) and α-fetoprotein >30 (OR 5.4, P = 0.031) as independent predictors of null response. Patients with SVR showed a better survival rate than those without SVR (P = 0.034). The second HCC recurrence rate tended to be lower in patients with SVR than in those without SVR (P = 0.054). With regard to the prognosis of patients with SVR, it is desirable to achieve SVR with interferon therapy even when administered after HCC treatment. IL-28B genotype is a potentially useful marker for the response to PEGIFN/RBV therapy administered after curative treatment of HCV-related HCC.

We evaluated the clinical features and the prognostic factors of hepatocellular carcinoma (HCC) developed after hepatitis C virus (HCV) eradication with interferon (IFN) therapy. Forty-one consecutive patients who developed HCC after HCV eradication with IFN therapy were enrolled. Clinical features were reviewed, and overall survival and associated factors were analyzed. The recurrence rate in 26 patients receiving radical therapy was also analyzed. Twenty patients developed HCC within 5 years after the end of IFN therapy, 9 patients developed the disease from 5 to 10 years after the end of the therapy, 9 patients developed the disease from 10 to 15 years after the end of the therapy, and 3 patients developed the disease from 15 years after the end of the therapy. Multivariate analysis of independent variables for the development of HCC within 5 years identified age >55 years at HCV eradication (P = 0.007) and heavy alcohol intake (P = 0.009). The 5-year survival rate was 64%. On multivariate analysis of overall survival for the 41 patients, the only risk factor with prognostic influence was radical therapy (P = 0.010), which was associated with a cumulative 5-year survival rate of 91%. The only independent factor for the receipt of radical therapy was regular surveillance for HCC (P = 0.004). Among patients receiving radical therapy, the 3- and 5-year recurrence rates were 18 and 18%, respectively. We found that, despite HCV eradication, patients with the risk factors of high age at HCV eradication and heavy alcohol intake might be at heightened risk for the development of HCC within 5 years after HCV eradication. In contrast, risk factors for the development of HCC more than 10 years after HCV eradication were uncertain. These findings indicate the need for long-term surveillance for HCC after HCV eradication.

AIM We conducted a retrospective cohort study to investigate the efficacy of combination therapy with radiotherapy (RT) and zoledronic acid for bone metastases from hepatocellular carcinoma (HCC). Additionally, we investigated the efficacy of zoledronic acid for non-irradiated bone metastases. METHODS This study consisted of 31 patients who had received RT for bone metastases. Twelve of these patients with 23 sites of bone metastases were also treated with zoledronic acid (Z group). In the Z group, 14 sites received RT and nine sites did not. Nineteen patients with 38 sites of bone metastases were not treated with zoledronic acid (non-Z group). In the non-Z group, 22 sites received RT and 16 did not. We compared survival, pain response, time to pain progression, radiographic response, time to radiographic progression, and safety between groups. RESULTS While pain response rates were similar between the two groups, time to pain progression rates of irradiated and non-irradiated bone metastases was significantly lower in the Z (0% and 20% at 6 months, respectively) than in the non-Z group (34% and 66% at 6 months, respectively) (P = 0.045 and P = 0.005). Further, while radiographic response rates were similar between the two groups, time to radiographic progression rate of non-irradiated bone metastases was significantly lower in the Z (29% at 3 months) than in the non-Z group (91% at 3 months) (P = 0.009). No significant side-effects were documented. CONCLUSION Zoledronic acid delayed the pain progression of both irradiated and non-irradiated bone metastases and the radiographic progression of non-irradiated bone metastases from HCC.

Aim: We compared the ability of five staging system to predict survival in patients with hepatocellular carcinoma (HCC) treated with chemoembolization. Methods: The study subjects were 214 patients with HCC treated with repeated chemoembolization alone using cisplatin and lipiodol. Predictors of survival were assessed by multivariate analysis. Before chemoembolization was carried out, the modified Japan Integrated Staging (m-JIS), Japan Integrated Staging (JIS score), Barcelona (BCLC) stage, Liver Cancer Study Group of Japan/Tumor–Node–Metastasis (LCSGJ/TNM) and Italian score (CLIP score) were checked. To validate the prognostic value of these staging systems, the survival curve was obtained and analyzed by the Kaplan–Meier method. Discriminatory ability and predictive power were compared using Akaike's information criterion (AIC) score and the likelihood ratio (LR) χ2. Results: Overall survival was 1 year in 82.9%, 3 years in 39.9% and 5 years in 15.1%. Multivariate analysis identified more than 90% lipiodol accumulation (grade I) after the first chemoembolization (P = 0.001), absence of portal vein tumor thrombosis (PVTT) (P

Purpose To assess the predictors of hypersensitivity reaction to chemoembolization procedures with cisplatin and Lipiodol suspension for the treatment of hepatocellular carcinoma (HCC). Materials and Methods Between February 2005 and December 2008, 434 patients with HCC were treated with chemoembolization with a cisplatin and Lipiodol suspension. This retrospective cohort study analyzed the incidence of hypersensitivity reactions as an adverse effect and their predictors by multivariate logistic regression analyses. Results In total, 847 chemoembolization procedures were carried out in 434 patients. The median number of procedures per patient was 2 (range, 1–12). Mean dose of cisplatin per chemoembolization session was 27 mg (range, 15.0–80.0 mg), and the median total dose of cisplatin per patient was 55 mg (range, 5.0–560.0 mg). Hypersensitivity reactions occurred in 14 patients (1.7%). The median number of chemoembolization procedures in these patients was 7 (range, 3–10). Mean dose of cisplatin per session was 22 mg (range, 9.2–35.7 mg), and the median total dose of cisplatin was 134 mg (range, 37–286 mg). On multivariate analysis, the only parameter that showed an independent association with hypersensitivity reactions was the performance of 3 or more than three chemoembolization procedures. Conclusions Performance of more than three chemoembolization procedures with a cisplatin and Lipiodol suspension was found to be independently associated with hypersensitivity reactions. Patients undergoing repeated chemoembolization procedures with cisplatin and Lipiodol suspension may experience hypersensitivity reactions as an adverse effect.

The aim of the present retrospective study was to evaluate the therapeutic efficacy and predictive factors of prolongation of treatment with peginterferon (PEGIFN) combined with ribavirin (RBV) for recurrent hepatitis C after living donor liver transplantation (LDLT).Fifty-three patients underwent LDLT due to HCV-related end-stage liver disease. Sixteen patients were removed from the study as a result of early death (n=14), no recurrence of HCV (n=1) and refusal of antiviral therapy (n=1). Therapy is ongoing in another 10 patients. The remaining 27 patients were available to establish the efficacy of IFN therapy. HCV genotype was 1b in 24 patients. All patients with genotype 1b were treated with IFN therapy for at least 48 weeks after HCV RNA levels had become undetectable. Amino acid substitutions in the HCV core region and NS5A region were analyzed by direct sequencing before LDLT.The rate of sustained virological response (SVR) was 37.0% (10/27). SVR rate in patients with genotype 1 was 29.2% (7/24) and 100% (3/3) in patients with genotype 2. Most patients with genotype 1b whose HCV RNA reached undetectable levels achieved SVR (87.5%; 7/8). However, mutation of the HCV core region and number of ISDR mutations were not associated with SVR rate in LDLT in our study.Prolonged IFN therapy for more than 48 weeks after HCV RNA reached undetectable levels might prevent virological relapse of HCV.

Background and Aims: We investigated the efficacy of intra-arterial 5-fluorouracil (5-FU) and systemic interferon (IFN)-α (5-FU-IFN) in the treatment of hepatocellular carcinoma (HCC) with portal vein tumor thrombosis in the first branch or trunk (Vp3/4) and extrahepatic metastases. Methods: We examined 17 HCC patients with Vp3/4 and extrahepatic metastases (meta group) and 31 HCC patients with Vp3/4 (non-meta group). Baseline intrahepatic tumor factors and the hepatic reserve were similar between groups. The extrahepatic metastases of the meta group were not considered prognostic factors. Following the administration of 5-FU/IFN to all patients, we compared the survival rates, response, time to progression (TTP), and safety between groups. Results: For intrahepatic HCC, complete response, partial response, stable disease, progressive disease, and drop out were observed in no (0%), one (6%), seven (41%), nine (53%), and no (0%) patients of the meta group, and in five (16%), seven (23%), 13 (42%), five (16%) and one (3%) patient of the non-meta group, respectively. The response rate was significantly lower in the meta group (6% vs 39%, P = 0.018). The median TTP of intrahepatic HCC and the median survival time were significantly shorter in the meta group than in the non-meta group (1.6 vs 6.3 months, P = 0.0001, and 3.9 months vs 10.5 months, P

We evaluate the long-term prognosis and prognostic factors in patients treated with transarterial infusion chemotherapy using cisplatin-lipiodol (CDDP/LPD) suspension with or without embolization for unresectable hepatocellular carcinoma (HCC). Study subjects were 107 patients with HCC treated with repeated transarterial infusion chemotherapy alone using CDDP/LPD (adjusted as CDDP 10mg/LPD 1ml). The median number of transarterial infusion procedures was two (range, one to nine), the mean dose of CDDP per transarterial infusion chemotherapy session was 30 mg (range, 5.0–67.5 mg), and the median total dose of transarterial infusion chemotherapy per patient was 60 mg (range, 10–390 mg). Survival rates were 86-0x1.fc400000008p+0t 1 year, 40 0x1.c617665206557p+855t 3 years, 20 0x1.5687420657461p-505t 5 years, and 16 0x1.5742d676e6f6cp+807t 7 years. For patients with >90% PD accumulation after the first transarterial infusion chemotherapy, rates were 98 0x1.e676f7270206dp+759t 1 year, 60 0x1.46e6120736973p-505t 3 years, and 22 0x1.36f6e676f727p+840t 5 years. Multivariate analysis identified >90% PD accumulation after the first transarterial infusion chemotherapy (p = 0.001), absence of portal vein tumor thrombosis (PVTT; p < 0.001), and Child-Pugh class A (p = 0.012) as independent determinants of survival. Anaphylactic shock was observed in two patients, at the fifth transarterial infusion chemotherapy session in one and the ninth in the other. In conclusion, transarterial infusion chemotherapy with CDDP/LPD appears to be a useful treatment option for patients with unresectable HCC without PVTT and in Child-Pugh class A. LPD accumulation after the first transarterial infusion chemotherapy is an important prognostic factor. Careful consideration should be given to the possibility of anaphylactic shock upon repeat infusion with CDDP/LPD.

Liver transplantation (LT) is known to improve bleeding esophageal varices (EVs) and portal hypertension. However, many issues related to EVs after LT remain unresolved, such as whether LT reduces blood supply to EVs, improves the diameter of unruptured EVs, or improves or worsens EVs. The aim of this retrospective study was to determine the effects of living-donor liver transplantation (LDLT) in patients with hepatic failure on EVs and inflow vessels to EVs and the factors associated with deterioration of EVs after LDLT.The study subjects were 35 patients with cirrhosis who underwent LDLT. Endoscopy and multidetector helical computed tomography (MDCT) were performed before and after LDLT. The diameter of the inflow vessel of EVs was measured by MDCT before and after LDLT, together with the LDLT-related reduction rate of the diameter of the gastric vein (RRGV).Endoscopic examination showed improvement of EVs in 30 of 35 (86%) patients. RRGV improved in 17/35 (49%) patients, did not change in 13/35 (37%), and deteriorated in 5/35 (14%). The cause of RRGV deterioration seemed to be either the complication of portal vein or graft failure. In patients examined endoscopically at1 year after LDLT, improvement of EVs was associated with significant changes in the rate of reduction of the major inflow vessel diameter and Child-Pugh score, compared with those who showed no improvement.LDLT results in improvement of EVs. EVs improved in 86% of the patients. Measurement of RRGV with MDCT is a good tool for prediction of EV improvement after LDLT.

Background and Aim: Acute liver failure (ALF) remains a devastating disease carrying considerable mortality. Since deceased donor liver transplantation is rarely performed in Japan, the artificial liver support system (ALS) and living donor liver transplantation (LDLT) are the main modalities used for treatment of ALF. The aim of this study was to analyze the outcome of ALF patients and to evaluate therapies for ALF according to etiology. Methods: Fifty consecutive patients with ALF were treated between January 1990 and December 2006. Prior to 1997, patients received ALS only. After 1997, ALS and/or LDLT were applied. LDLT was performed in 10 patients. Results: Four of 15 (27%) pre-1997 ALF patients survived, and 16 of 35 (46%) post-1997 ALF patients survived, including eight who underwent LDLT. The causes of ALF were acute hepatitis B virus (HBV) infection in 18%, severe acute exacerbation (SAE) of chronic HBV infection in 18%, autoimmune hepatitis (AIH) in 8%, and cryptogenic hepatitis in 44%. In total, 67% of the patients with ALF caused by acute HBV infection and AIH were cured without LDLT; only 11% of patients with ALF caused by SAE of HBV and 24% of cryptogenic hepatitis were successfully treated without LDLT. Notably, 80% of patients with cryptogenic hepatitis who underwent LDLT survived. Conclusion: Since 1997, the survival rate of ALF patients has increased, mainly due to the introduction of LDLT. Liver transplantation should be performed especially in patients with ALF caused by SAE of HBV and cryptogenic hepatitis.

It is well known that the incidence of hepatocellular carcinoma (HCC) in patients with hepatitis C virus (HCV) correlates with progression of liver fibrosis. However, there is little information on the impact of aging on hepatocarcinogenesis. The aim of this study was to elucidate the clinicopathological features of elderly patients with HCV-related HCC. The study subjects were 693 consecutive patients newly diagnosed with HCC with anti-HCV. First, we divided them into a younger group (

The purpose of our study was to evaluate the long-term outcome and complications of balloon-occluded retrograde transvenous obliteration (B-RTO) in patients with hemorrhage from gastric fundal varices.Thirty-four consecutive patients with bleeding from gastric varices who were treated with B-RTO were enrolled in this study between December 1994 and September 2005 (urgent cases, n = 12; elective cases, n = 22). The long-term outcome, complications, and various liver functions were evaluated.Complete obliteration was achieved in 31 of 34 (91%) patients with an acute bleeding episode. In one of the remaining patients, there was a technical failure, and the other two had only partial obliteration. The two patients with partial obliteration did not obtain hemostasis. Thus, the rate of hemostasis was 94% (31/33). Gastric varices disappeared in all patients with complete obliteration during the treatment. The rate of gastric variceal eradication was 91%. Variceal rebleeding from esophageal varices occurred in three patients. The rate of rebleeding was 10% (3/31). Rebleeding from gastric varices was not observed after complete obliteration. None of the patients showed worsening of their Child-Pugh score. Although the 5-year cumulative worsening rate of esophageal varices was 52%, neither portal hypertensive gastropathy nor ectopic varices were observed. The patients with worsening esophageal varices were successfully treated with an endoscopic procedure. The 5-year survival rate was 68%.B-RTO is useful for treatment of bleeding gastric varices, achieving high eradication of gastric varices, a low rebleeding rate, and a fairly good prognosis with improved hepatic function.

Objective: To evaluate the efficacy of eicosapentaenoic acid (EPA) against ribavirin (RBV)-associated hemolytic anemia during the first 12 weeks in chronic hepatitis C virus (HCV) combination therapy. Methods: This study was a prospective open-label, randomized controlled trial. 100 HCV patients were randomized to either the EPA group (n = 49) or non-EPA group (n = 51) who received combination therapy with or without EPA. We compared the changes in hemoglobin level and RBV plasma concentrations at week 12 in each group with RBV dose reduction rate and performed multivariate analysis to identify independent variables associated with RBV dose reduction. Results: 8 patients (17%) in the EPA group and 20 patients (29%) in the non-EPA group required RBV dose reduction, respectively. The cumulative RBV reduction rate was significantly lower in the EPA group than in the non-EPA group (p = 0.017), while the decrease of hemoglobin and RBV plasma concentrations from baseline was not significantly different. However, in the multivariate analysis, treatment with EPA showed significant variables for the reduction of RBV dose (odds ratio 3.235, p = 0.023). Conclusion: EPA could prevent the RBV dose reduction during the first 12 weeks in combination therapy, although further large-scale double-blind randomized controlled trials are required.

Recent studies indicate that combination therapy with ribavirin and interferon alfa2b (IFNAlpha2b) is effective for chronic hepatitis C virus (HCV) infection. However, reversible hemolytic anemia is a common side effect of this therapy.We determined those factors that contribute to ribavirin dose reduction due to anemia during this treatment by using multiple logistic regression analysis in Japanese patients. The study included 123 patients with chronic hepatitis C (85 male, 38 female; mean age, 50 years; range, 20-70 years), who received 24-week combination therapy. All patients were treated with IFNAlpha2b daily for 2 weeks, followed by three times weekly dosing for 22 weeks, with oral ribavirin twice daily, at a total daily dose of 600 or 800 mg.Of the 123 patients, 34 patients required dose reduction of ribavirin, and 78 patients required no dose reduction. Overall, 20 patients discontinued. On univariate analysis, reduction of the ribavirin dose correlated significantly with pretreatment hemoglobin (Hb) levels of less than 14 g/dl, female sex, and patient age 55 years or older. On multivariate analysis, pretreatment Hb of less than 14 g/dl level and age 55 years or older were significantly associated with ribavirin dose reduction. The hazard ratios were 3.56 (95% confidence interval [CI], 1.48-8.53) for pretreatment Hb levels of less than 14 g/dl, and 2.50 (95% CI, 1.05-5.94) for age 55 years or more.Because patient age of 55 years or more, and Hb levels of less than 14 g/dl are significant factors that influence ribavirin-induced hemolytic anemia, more careful monitoring is necessary during combination therapy for patients with these risk factors.

We aimed to identify risk factors contributing to the exacerbation of esophageal varices (EV) or portosystemic encephalopathy after hepatitis C virus (HCV) eradication with interferon (IFN) therapy in patients with compensated cirrhosis. Also, the prognosis after HCV eradication was analyzed. Fifty-two patients with sustained virological response to IFN treatment for HCV-related compensated cirrhosis were enrolled in this retrospective cohort study. At the achievement of HCV eradication, in 31 of the 52 patients (60 %), feeding vessels for EVs (left gastric vein, posterior gastric vein, short gastric vein) were shown, and in 18 patients (35 %) there were extrahepatic portosystemic shunts (paraesophageal vein, paraumbilical vein, and splenorenal shunt). Although the HCV eradication was successful, significant improvements were not observed in portosystemic collateral vessels 1 year after HCV eradication, and EVs were exacerbated in 19 (36 %) patients. The cumulative 1- and 3-year rates of EV exacerbation were 13 % and 49 %, respectively. By multivariate analysis, the existence of feeding vessels for EVs at HCV eradication was an independent predictive factor for the exacerbation of EVs (P = 0.009). Seven patients who had an extrahepatic portosystemic shunt at HCV eradication developed portosystemic encephalopathy during follow up. The 1-, 3-, and 5-year incidences of portosystemic encephalopathy were 6, 21, and 34 %, respectively. The cumulative 5-year survival rate of the cohort was 81 %. Two patients died of hepatocellular carcinoma (HCC). Our findings suggest that the existence of radical portosystemic collateral vessels at successful HCV eradication increases the risk of the exacerbation of EVs and the incidence of portosystemic encephalopathy in patients with HCV-related cirrhosis.

BACKGROUND The purpose of this study was to evaluate both safety of diet-treated donors and the feasibility of their use for living-donor liver transplantation (LDLT). METHODS A total of 128 living donors were enrolled in this study between April 2003 and March 2010. Of them, 41 were diagnosed with hepatic steatosis at the initial consultation. Donor selection was based on the findings of liver biopsy accompanied with normalization of liver function tests after diet treatment consisting of an 800 to 1400 kcal/day diet and a 100 to 400 kcal/day exercise without drug treatment, targeting body mass index of 22 kg/m². RESULTS Body mass index of diet-treated donors was significantly reduced with diet from 23.3 ± 0.6 to 21.9 ± 0.4 kg/m² (P

A 68-year-old Japanese woman with chronic hepatitis C infection who achieved sustained viral response (SVR) was followed up regularly. Six years after SVR, alpha fetoprotein (AFP) was increased. Hepatocellular carcinoma (HCC) was diagnosed by computed tomography and was excised by hepatic resection. Thirteen years after SVR, AFP increased again, and HCC recurrence was detected, which was excised by hepatic resection. Each HCC was

A 54-year-old man maintained on hemodialysis had a relapse of multiple pulmonary metastases after multimodal therapy for primary hepatocellular carcinoma (HCC). He was treated with tegafur-uracil (UFT; 400 mg/day) and interferon alfa (IFN-alpha; 5 x 10(6) units three times per week) for 4 weeks. Following this he was treated with systemic 5-fluorouracil (5-FU; 1000 mg/day, 5 days per week) and cisplatin (CDDP; 10 mg/day, 5 days per week for 2 weeks). The response to the above treatments was inadequate; pulmonary metastasis deteriorated. Finally, we selected systemic chemotherapy of 5-FU (750 mg/day, 5 days per week) and recombinant IFN-alpha-2b (3 x 10(6) units three times per week) for 2 weeks. This therapy resulted in excellent shrinkage of pulmonary metastases, without severe adverse reactions. Hemodialysis was performed three times a week. We report a case of successful treatment of pulmonary metastases by systemic combination chemotherapy of 5-FU-IFN, previously unsuccessfully treated with UFT-IFN and 5-FU-CDDP in a patient on hemodialysis. Further studies are needed to select appropriate drugs with fluoropyrimidine-based systemic chemotherapy, and to analyze the pharmacokinetics of those agents in hemodialysis patients with HCC and extrahepatic metastases.

The aim of this study was to elucidate the efficacy of intra-arterial 5-fluorouracil (5-FU) and interferon (IFN) alpha combined with three-dimensional conformal radiotherapy (3D-CRT) for portal vein tumor thrombosis (PVTT).The study groups were 16 HCC patients with PVTT treated with 5-FU/IFN combined with 3D-CRT (RT group) and 16 matched controls treated with 5-FU/IFN alone (non-RT group). We compared the survival rate, response, time to progression (TTP), portal hypertension-related events (PREs) and safety.Complete response (CR) of PVTT, partial response (PR), stable disease (SD) and progressive disease (PR) were noted in three (19%), nine (56%), four (25%) and zero patients of the RT group, one (6%), three (19%), seven (44%) and five (31%) patients of the non-RT group, respectively. The objective response rate of PVTT was higher in the RT group (P = 0.012). The rate of PREs (variceal rupture, worsening of esophagogastric varices and emerging of uncontrollable ascites) was lower in the RT group than in the non-RT group (P = 0.0195). The median survival time of the RT group (7.5 months) was not significantly different from that of the non-RT group (7.9 months). RT-induced liver disease was not observed.5-FU/IFN combination with 3D-CRT for PVTT improved the response rate of PVTT and reduced the incidence of portal hypertension-related events.
