Patients with thrombocytopenia and chronic liver disease are at increased risk of bleeding during invasive procedures due to low platelet counts. Lusutrombopag, an orally active thrombopoietin receptor agonist, increases platelet count and reduces the need for platelet transfusion in chronic liver disease patients with thrombocytopenia undergoing a planned invasive procedure. The safety of lusutrombopag in patients with Child-Pugh class C chronic liver disease is not known. The present analysis was performed to determine the pharmacokinetics, efficacy, and safety of lusutrombopag in patients with Child-Pugh class C chronic liver disease.Data for patients with Child-Pugh class C chronic liver disease were collected from three data sets: a phase 1/2 Child-Pugh class C study (n = 5) (JapicCTI-163289 [Japan Pharmaceutical Information Center]), a phase 3 pivotal study (L-PLUS 2, n = 3) (NCT02389621 [Clinicaltrials.gov]), and ongoing post-marketing surveillance (n = 27) (JapicCTI-163432 [Japan Pharmaceutical Information Center]). Patients received lusutrombopag at 3 mg for up to 7 days. Safety and efficacy assessments were collected from two clinical studies and the post-marketing surveillance; pharmacokinetic data were collected from the phase 1/2 study.Mean CThe analysis presented in this study suggests that lusutrombopag increases platelet counts in Child-Pugh class C patients and is safe and well tolerated in this patient population.L-PLUS 2: NCT02389621 (Clinicaltrials.gov). Phase 1/2: JapicCTI-163289 (Japan Pharmaceutical Information Center [JAPIC]). Post-marketing surveillance: JapicCTI-163432 (JAPIC).

Combination chemotherapy with gemcitabine, nab-paclitaxel, oxaliplatin, and itraconazole (GnPO-ITC) was administered as first-line chemotherapy in patients with metastatic pancreatic cancer (mPC). The efficacy and toxicity of these treatments were retrospectively investigated.A total of 81 patients (mean age=64 years) with an Eastern Cooperative Oncology Group (ECOG) performance status of 0-1 were enrolled in the study, and administered nab-paclitaxel (125 mg/mMetastatic sites observed in patients included the liver (n=55, 68%), peritoneum (n=23, 28%), distant lymph nodes (n=24, 30%), and lungs (n=18, 22%). Within 28 days after initiation of chemotherapy, 15 patients (19%) experienced common ≥3 grade hematological adverse events. The major reason for discontinuation of treatment among the responders was peripheral sensory neuropathy in 36 patients (44%). The overall response rate to treatment was 64% [95% confidence interval (CI)=54-75%]. The median progression-free survival and median overall survival were 8.3 months (95% CI=6.8-9.8 months) and 14.4 months (95% CI=11.4-17.3 months), respectively. Among the 52 responders, 24 (46%) underwent conversion surgery, which did not improve survival (p=0.279). Second-line treatment with irinotecan was required in 71 (88%) patients. Hepatic arterial chemotherapy and radiotherapy were administered to 33 (41%) and 27 (33%) patients, respectively.The GnPO-ITC regimen showed promising efficacy with manageable toxicities for controlling disease progression and improving overall survival.

Aim Lusutrombopag is approved for thrombocytopenia in chronic liver disease patients planned to undergo invasive procedures. In previous clinical studies, lusutrombopag treatment was stopped in patients with an increase in platelet count (PC) of ≥20×109 /L from baseline and whose PC was ≥50×109 /L (discontinuation criteria). We assessed the influences of platelet monitoring during lusutrombopag administration in lusutrombopag naive patients. Methods In this open-label study, Child-Pugh class A and B (A/B) patients were enrolled and treated with lusutrombopag (3 mg/day) for 7 days. In the treatment-naive A/B-1 group, the discontinuation criteria were applied on Day 6. In the treatment-naive A/B-2 group, the criteria were not applied. In a non-naive A/B group, the criteria were applied on Days 3 and 5-7. The main efficacy endpoint was the proportion of patients without platelet transfusion (PT) before the primary invasive procedure. Results In the A/B-1, A/B-2, and non-naive A/B groups, the proportions of patients without PT were 80.9% (38/47), 83.0% (39/47), and 75.0% (6/8), respectively. The mean durations of PC ≥50×109 /L without PT were 20.7, 20.3, and 22.8 days, respectively. Excessive PC increases (≥200x109 /L) were not detected in any group. Treatment-related adverse events occurred in 4.3%, 6.4%, and 0% of A/B-1, A/B-2, and non-naive A/B patients, respectively. Severe portal vein thrombosis occurred in one A/B-2 patient (PC 75×109 /L at onset). Conclusions No meaningful efficacy and safety differences were observed among the groups with or without discontinuation criteria and the non-naive group. These findings support lusutrombopag administration without platelet monitoring and retreatment with lusutrombopag.

Purpose: This study aimed to evaluate Japanese patient preferences regarding features of intermediate or advanced (Progressed) hepatocellular carcinoma (HCC) treatments: transarterial chemoembolization (TACE), hepatic arterial infusion chemotherapy (HAIC), and oral anti-cancer therapy. Methods: Patients with HCC, recruited from clinical sites and a patient panel in Japan, completed a cross-sectional web-based survey. Preferences were quantified using best-worst scaling, where patients identified the best and worst among 13 treatment features. Direct elicitation was used to identify preference for TACE, HAIC, or oral therapy, including the likelihood of trying each. Additional items asked for the willingness to try an oral medication that delays progression by six months but has an 8% or 21% risk of severe hand-foot skin reaction (HFSR). Results: The sample (N=119; 29 early stage; 90 Progressed) most preferred "oral medication", "artery branches plugged", and "prevents formation of new blood vessels", and least preferred "risk of liver damage" and "risk of catheter-related complications". Overall, 51%, 40%, and 8% preferred oral therapy, TACE, and HAIC, respectively (p

Background & Aims Despite limitations, platelet transfusion has been used to minimise bleeding risk in patients with thrombocytopaenia. Lusutrombopag is an oral, thrombopoietin receptor agonist approved for treatment of thrombocytopaenia associated with chronic liver disease in patients undergoing planned invasive procedures. This post-hoc analysis assessed the magnitude of platelet count change based on the integrated per-protocol population from 2 similar phase III multicentre, randomised, double-blind, placebo-controlled trials. Methods Adults with chronic liver disease-induced thrombocytopaenia and platelet count, Graphical abstract, Highlights • Thrombocytopaenia is common in patients with chronic liver disease. • Lusutrombopag increased platelet count ≥1.5-fold in most patients with chronic liver disease-induced thrombocytopaenia. • Lusutrombopag doubled platelet count in half of patients treated. • Lusutrombopag-induced platelet count increases (without platelet transfusion) lasted for 3 weeks.

Background & Aims Ultrasound (US)-based screening has been recommended for patients with an increased risk of hepatocellular carcinoma (HCC). US analysis, however, is limited in patients who are obese or have small tumors. The addition of serum level of α-fetoprotein (AFP) measurements to US analysis can increase detection of HCC. We analyzed data from patients with chronic liver disease, collected over 15 years in an HCC surveillance program, to develop a model to assess risk of HCC. Methods We collected data from 3450 patients with chronic liver disease undergoing US surveillance in Japan from March 1998 through April 2014, and followed them up for a median of 8.83 years. We performed longitudinal discriminant analysis of serial AFP measurements (median number of observations/patient, 56; approximately every 3 months) to develop a model to determine the risk of HCC. We validated the model using data from 2 cohorts of patients with chronic liver disease in Japan (404 and 2754 patients) and 1 cohort in Scotland (1596 patients). Results HCC was detected in 413 patients (median tumor diameter, 1.8 cm), during a median follow-up time of 6.60 years. In the development data set, the model identified patients who developed HCC with an area under the curve of 0.78; it correctly identified 74.3% of patients who did develop HCC, and 72.9% of patients who did not. Overall, 73.1% of patients were classified correctly. The model could be used to assign patients to a high-risk group (27.5 HCCs/1000 patient-years) vs a low-risk group (4.9 HCCs/1000 patient-years). A similar performance was observed when the model was used to assess patients with cirrhosis. Analysis of the validation cohorts produced similar results. Conclusions We developed and validated a model to identify patients with chronic liver disease who are at risk for HCC based on change in serum AFP level over time. The model could be used to assign patients to high-risk vs low-risk groups, and might be used to select patients for surveillance.

We experienced two cases of hepatocellular carcinoma (HCC) occurring immediately after treatment with direct-acting antiviral agents (DAAs). Case 1 was a 75-year-old woman in whom HCC was detected immediately after completion of DAA treatment. Case 2 was a 75-year-old woman who had a hypovascular nodule in liver. The hypovascular nodule became hypervascular without enlargement of the nodule size immediately after DAA treatment completion. Although the association between DAA treatment and hepatocarcinogenesis is unknown, sufficient surveillance after achieving a sustained viral response is required, as a large number of patients at a high risk of hepatocarcinogenesis are treated with DAAs.

Background: Current practice guidelines recommend the use of ultrasound (US) as an initial surveillance tool for hepatocellular carcinoma (HCC) in patients with liver cirrhosis. Patients with liver cirrhosis, however, frequently have coarse liver parenchyma, masking the presence of tiny nodules during B-mode US. Contrast-enhanced US (CEUS) with Sonazoid has a long-lasting, stable Kupffer phase, which makes it possible to scan the entire liver to depict small lesions. In addition, defect reperfusion imaging (reinjection imaging) enables to determine whether the detected nodule is HCC or not. This prospective, multicenter, randomized, controlled trial was conducted to demonstrate the usefulness of Kupffer phase surveillance in the detection of small HCC compared to B-mode US. Methods: A total of 23 institutions joined this study. In total, 656 patients with hepatitis B- or C-related liver cirrhosis were randomized either to the B-mode US surveillance group (n = 313) or the Kupffer phase CEUS with Sonazoid surveillance group (n = 309). The primary endpoint was the maximum size of HCC at the time of the first detection. Secondary endpoints included time to HCC detection, number of tumors, and Barcelona Clinic Liver Cancer stage at the first detection, and sensitivity, specificity, and accuracy of each method in the diagnosis, and the cumulative detection rate of HCC. Results: The mean HCC size at the first detection was significantly smaller in the CEUS (13.0 ± 4.1 mm; n = 28) than in the B-mode US group (16.7 ± 4.1 mm; n = 26) (p = 0.011). Of the 38 patients with HCV cirrhosis diagnosed with HCC by US alone, mean tumor size at the first detection was significantly smaller in the 20 patients diagnosed by CEUS alone than in the 18 diagnosed by B-mode US alone (12.7 ± 3.1 vs. 17.6 ± 7.0 mm, p = 0.012). In contrast, among the 16 patients with HBV cirrhosis diagnosed by US alone, mean tumor size at the first detection was similar in the 8 patients diagnosed by CEUS alone and the 8 diagnosed by B-mode US (13.6 ± 6.0 vs. 14.5 ± 2.7 mm, p = 0.715). Conclusion: Kupffer phase CEUS surveillance with Sonazoid is extremely useful for the early detection and confirmation of HCC using a reinjection technique. Kupffer phase CEUS with Sonazoid contrast combined with the reinjection technique is, therefore, recommended as first-line screening tool for HCC in patients with liver cirrhosis, especially those with very coarse liver parenchyma.

Lenvatinib is a novel multikinase inhibitor that has recently shown antitumor activity against hepatocellular carcinoma (HCC) in a phase III trial. We report the case of a woman in whom lenvatinib showed long-term antitumor activity, and in whom computed tomography (CT) scans revealed a series of suggestive radiological changes on the intratumor vascularity. A 68-year-old woman with hepatitis C virus-related liver disease presented with multiple HCCs. Following previous therapy, including six sessions of transcatheter arterial chemoembolization, we introduced lenvatinib monotherapy. Lenvatinib could rapidly cause hypovascularity in the main hypervascular target lesion, and portal vein tumor thrombosis also became undetectable 11 months after the initiation of lenvatinib. These radiological changes suggested that lenvatinib could exert not only anti-angiogenic activity but also direct antitumoral effect. Of note, CT scans during lenvatinib treatment revealed the target lesion as a low-density area in the early arterial phase, whereas scans during drug interruption due to proteinuria showed that the lesion was enhanced in the arterial phase. Finally, near-complete response could be achieved as the best response. We successfully managed various adverse events including proteinuria and hypertension, and the patient was able to continue this lenvatinib therapy for more than 4 years with well-controlled general condition. We report the first case of a patient with HCC in whom lenvatinib monotherapy demonstrated long-term antitumor activity. Suggestive radiological changes reflecting intratumor vascularity as presented here should be considered in patients receiving lenvatinib for HCC.

Background Thrombocytopenia represents an obstacle for invasive procedures in chronic liver disease (CLD) patients. We aimed to estimate the appropriate dose and evaluate the efficacy and safety of lusutrombopag for the treatment of thrombocytopenia before percutaneous liver radiofrequency ablation (RFA) for primary hepatic cancer in patients with CLD. Methods In this multicenter, randomized, double-blind, placebo-controlled study conducted in Japan, 61 CLD patients with platelet count

Background and study aims Rectal neuroendocrine tumors grade 1 (NET G1; carcinoid) ≤ 10 mm in diameter often extend into the submucosa, making their complete histological resection difficult using endoscopic techniques. Endoscopic submucosal resection with a ligation device (ESMR-L) and endoscopic submucosal dissection (ESD) are commonly used to overcome these difficulties. We also previously reported that underwater endoscopic mucosal resection (UEMR) could facilitate resection of rectal NET G1. This study aimed to evaluate the safety and efficacy of UEMR for removing rectal NET G1 ≤ 10 mm in diameter. 6 consecutive patients with rectal NET G1 ≤ 10 mm in diameter underwent UEMR at our hospital. The rate of en bloc resection was 100 %, and the rate of R0 resection was 83 %. The median procedure time was 8 min (range 5 – 12 min). No perforations or delayed bleeding occurred in this study. In conclusion, UEMR allows the safe and reliable resection of rectal NET G1 ≤ 10 mm in diameter with comparable results to ESMR-L or ESD, including high en bloc and R0 resection rates with no increase in significant adverse events. A multicenter trial is required to confirm the validity of the present results.

Glecaprevir (nonstructural protein 3/4A protease inhibitor) and pibrentasvir (nonstructural protein 5A inhibitor) (G/P), a coformulated once‐daily, all oral, ribavirin (RBV)‐free, direct‐acting antiviral regimen, was evaluated for safety and efficacy in hepatitis C virus genotype 2 (GT2)–infected Japanese patients, including those with compensated cirrhosis. CERTAIN‐2 is a phase 3, open‐label, multicenter study assessing the safety and efficacy of G/P (300/120 mg) once daily in treatment‐naive and interferon ± RBV treatment–experienced Japanese patients without cirrhosis but with GT2 infection. Patients were randomized 2:1 to receive 8 weeks of G/P (arm A) or 12 weeks of sofosbuvir (400 mg once daily) + RBV (600‐1000 mg weight‐based, twice daily) (arm B). The primary endpoint was noninferiority of G/P compared to sofosbuvir + RBV by assessing sustained virologic response at posttreatment week 12 (SVR12) among patients in the intent‐to‐treat population. SVR12 was also assessed in treatment‐naive and interferon ± RBV treatment‐experienced patients with GT2 infection and compensated cirrhosis who received G/P for 12 weeks in the CERTAIN‐1 study. A total of 136 patients were enrolled in CERTAIN‐2. SVR12 was achieved by 88/90 (97.8%) patients in arm A and 43/46 (93.5%) patients in arm B. No patient in arm A experienced virologic failure, while 2 did in arm B. The primary endpoint was achieved. In CERTAIN‐1, 100% (18/18) of GT2‐infected patients with compensated cirrhosis achieved SVR12. Treatment‐emergent serious adverse events were experienced by 2 patients without cirrhosis in each arm and no patient with cirrhosis. Conclusion: The results demonstrate high efficacy and favorable tolerability of G/P in GT2‐infected Japanese patients. (Hepatology 2018;67:505‐513).

Background Although the efficacy of combination therapy with lamivudine or tenofovir and pegylated interferon (PEG-IFN) has been reported in patients with chronic hepatitis B (CHB), the long-term effect of the combination based on the observation of clinical course remains to be clarified. We previously reported the efficacy of combination therapy with entecavir (ETV) and PEG-IFN. Here, we investigated the long-term effect of this combination in patients with CHB. Methods We administered both ETV and PEG-IFN-α2a or -2b simultaneously to 26 patients with HBV genotype C infection. Treatment was continued for 48 weeks followed by 24 weeks of observation period; we examined the virological and biochemical responses. We also analysed characteristics related to the post-treatment relapse. Finally, we investigated the long-term therapeutic effects. Results Average reduction of intra-hepatic cccDNA level was 1.2 log copies/μg at the completion of administration. Pretreatment hepatitis B surface antigen (HBsAg) level with more than 3.5 log U/ml was identified as a predictive factor for relapse. Furthermore, the cumulative rates of HBsAg-negative patients at 1, 3 and 5 years after the completion of administration were 3.8, 8.4 and 15%, respectively (mean follow-up period: 4.8 years). Conclusions Baseline HBsAg level with more than 3.5 log U/ml is a useful predictor for relapse 24 weeks after the completion of administration in patients treated with combination therapy. Combination with ETV and PEG-IFN could be an option for treatment of CHB patients especially in those with baseline HBsAg levels of less than 3.5 log U/ml.

The present study aimed to examine the impact of sarcopenia, defined as low muscle mass on computed tomography (CT), prior to sorafenib therapy on the clinical outcomes of patients with hepatocellular carcinoma (HCC) receiving sorafenib therapy. In total, 232 patients with unresectable HCC (median age, 72 years) were analyzed, and the extent of sarcopenia was assessed using CT. Cross-sectional areas (cm2) of the skeletal muscles at the third lumbar vertebra level were determined by manual outlining on the CT images. The cross-sectional areas were normalized for height [skeletal muscle index (SMI), cm2/m2]. Based on the findings of previous studies, male patients with SMI ≤36.2 cm2/m2 and female patients with SMI ≤29.6 cm2/m2 were defined as having sarcopenia. The baseline characteristics, overall survival (OS) rates, progression-free survival (PFS) rates and best treatment response of the sarcopenia group were retrospectively compared with those of the non-sarcopenia group, and the factors associated with OS and PFS were examined. Sarcopenia was observed in 151 patients (65.1%). There were 165 patients with Child-Pugh A and 67 with Child-Pugh B cirrhosis. In the sarcopenia group, the median treatment duration was 66 days, whereas in the non-sarcopenia group it was 103 days (P=0.001). The median OS time was 174 days in the sarcopenia group and 454 days in the non-sarcopenia group (P

Background & Aims: Patients with hepatocellular carcinoma (HCC) secondary to chronic liver disease often require invasive procedures but frequently have thrombocytopenia. Lusutrombopag is an agonist of the thrombopoietin receptor that activates platelet production. Methods: We performed an integrated analysis of data from 2 phase 3 trials (L-PLUS 1, Japan, October 2013 to May 2014, and L-PLUS 2, global, June 2015 to April 2017) that compared the efficacy and safety of lusutrombopag with placebo in patients with chronic liver disease, with and without HCC. Our analysis included patients with Eastern Cooperative Oncology Group grades of 0 or 1, Child–Pugh classes A or B, and a platelet count less than 50 × 109/L who were scheduled to undergo invasive procedures in 9 to 14 days. Patients received lusutrombopag (3 mg) or placebo daily for 7 days or fewer before an invasive procedure. Imaging studies assessed treatment-emergent adverse events, including asymptomatic portal vein thrombosis. The primary end point was no requirement for platelet transfusion before the invasive procedure and rescue therapies for bleeding 7 days or fewer after the invasive procedure. Results: The per-protocol population included 270 patients (95 with HCC). A significantly higher proportion of patients with HCC who received lusutrombopag achieved the primary end point (68.0%) vs patients who received placebo (8.9%) (P < .0001); in patients without HCC, these proportions were 77.0% vs 21.6% (P < .0001). Lusutrombopag reduced the need for platelet transfusions, increased platelet counts for 3 weeks, and reduced the number of bleeding events in patients with and without HCC compared with placebo. Risk of thrombosis was similar to that of placebo. Conclusions: Patients with and without HCC receiving lusutrombopag had a reduction in the number of platelet transfusions before invasive procedures compared with patients receiving placebo, with no increase in thrombosis or bleeding.

Aims: We sought to compare the effects of FIB-4 index and aspartate aminotransferase to platelet ratio index (APRI) on hepatocellular carcinoma (HCC) incidence in chronic hepatitis B (CHB) patients undergoing entecavir (ETV) therapy. Patient and methods: A total of 338 nucleosides analogue therapy naive CHB patients initially treated with ETV were analyzed. The optimal cutoff points in each continuous variable were determined by receiver operating curve (ROC) analysis. The effects of FIB-4 index and APRI on HCC incidence were compared using time-dependent ROC analysis and factors linked to HCC incidence were also examined using univariate and multivariate analyses. Results: There were 215 males and 123 females with the median age of 52 years and the median baseline HBV-DNA level of 6.6 log copies/ml. The median follow-up interval after the initiation of ETV therapy was 4.99 years. During the follow-up period, 33 patients (9.8%) developed HCC. The 3-, 5- 7-year cumulative HCC incidence rates in all cases were 4.4%, 9.2% and 13.5%, respectively. In the multivariate analysis, FIB-4 index revealed to be an independent predictor associated with HCC incidence, while APRI was not. In the time-dependent ROC analyses for all cases and for all subgroups analyses stratified by viral status or cirrhosis status, all area under the ROCs in each time point (2-, 3-, 4-, 5-, 6-, and 7-year) of FIB-4 index were higher than those of APRI. Conclusion: FIB-4 index rather than APRI can be a useful predictor associated with HCC development for CHB patients undergoing ETV therapy.

REACH evaluated ramucirumab in the second-line treatment of patients with advanced hepatocellular carcinoma. In the intent-to-treat population (n = 565), a significant improvement in overall survival (OS) was not observed. In patients with an elevated baseline α-fetoprotein (AFP) level (400 ng/mL or greater), an improvement in OS was demonstrated. An analysis of the Japanese patients in REACH was performed.An analysis was performed with the subset of the intent-to-treat population enrolled in Japan (n = 93).The median OS was 12.9 months for the ramucirumab arm (n = 45) and 8.0 months for the placebo arm (n = 48) [hazard ratio (HR) 0.621 (95 % confidence interval (CI) 0.391-0.986); P = 0.0416]. The median progression-free survival was 4.1 months for the ramucirumab arm and 1.7 months for the placebo arm [HR 0.449 (95 % CI 0.285-0.706); P = 0.0004]. The objective response rates were 11 % for the ramucirumab arm and 2 % for the placebo arm (P = 0.0817). The grade 3 or higher treatment-emergent adverse events occurring in more than 5 % of patients with a higher incidence for the ramucirumab arm (n = 44) than for the placebo arm (n = 47) were ascites (7% vs 2 %), hypertension (7 % vs 2 %), and cholangitis (7 % vs 0 %). In patients with a baseline AFP level of 400 ng/mL or greater, the median OS was 12.9 months for the ramucirumab arm (n = 20) and 4.3 months for the placebo arm (n = 22) [HR 0.464 (95 % CI 0.232-0.926); P = 0.0263].In the Japanese patients in REACH, ramucirumab treatment improved OS, including in patients with a baseline AFP level of 400 ng/mL or greater; improvements in progression-free survival and objective response rate were also demonstrated. The safety profile of ramucirumab was acceptable and well tolerated in Japanese patients. ClinicalTrials.gov identifier NCT01140347.

HBV reactivation could be induced under immunosuppressive conditions in patients with resolved infection. This study aimed to clarify the viral factors associated with the pathogenesis of HBV reactivation in association with the immunosuppressive status. Whole HBV genome sequences were determined from the sera of 24 patients with HBV reactivation, including 8 cases under strong immunosuppression mediated by hematopoietic stem cell transplantation (HSCT) and 16 cases without HSCT. Ultra-deep sequencing revealed that the prevalence of genotype B and the ratio of non-synonymous to synonymous evolutionary changes in the surface (S) gene were significantly higher in non-HSCT cases than in patients with HSCT. Those non-synonymous variants included immune escape (6/16 cases) and MHC class II-restricted T-cell epitope variants (6/16 cases). Furthermore, reactivated HBV in 11 of 16 (69%) non-HSCT cases possessed substitutions associated with impaired virion secretion, including E2G, L77R, L98V, T118K, and Q129H in the S region, and M1I/V in the PreS2 region. In conclusion, virologic features of reactivated HBV clones differed depending on the intensity of the immunosuppressive condition. HBV reactivation triggered by immunosuppressive conditions, especially those without HSCT, was characterized by the expansion of variants associated with immune escape, MHC class II-restricted T-cell epitope alterations, and/or impaired virion secretion.

Platelet transfusion is used to prevent hemorrhagic events in patients with thrombocytopenia undergoing invasive procedures, but there are many disadvantages. We evaluated the efficacy and safety of lusutrombopag in patients with chronic liver disease and thrombocytopenia undergoing invasive procedures.We performed a double-blind, parallel-group, phase 3 study of 96 patients with chronic liver disease and thrombocytopenia (platelet counts below 50,000/μL) undergoing invasive procedures from October 2013 to May 2014 at 81 centers in Japan. Patients were randomly assigned (1:1) to groups given once-daily lusutrombopag (3 mg) or placebo for up to 7 days. The primary efficacy endpoint was the proportion of patients not requiring platelet transfusion before the invasive procedure. The protocol-defined response (platelet count 50,000/μL or more with an increase of 20,000/μL or more from baseline) and the time course of the change in platelet count were also evaluated. Adverse events were recorded.The proportions of patients who did not require preoperative platelet transfusion were 79.2% (38/48) in the lusutrombopag group and 12.5% (6/48) in the placebo group (P.0001). A response was observed in 77.1% (37/48) of patients in the lusutrombopag group and 6.3% (3/48) of patients in the placebo group (P.0001). In the lusutrombopag group without platelet transfusion, the median platelet count was 50,000/μL or more after 5 days; the mean time to reach the maximum platelet count was 13.4 days; and the number of days (adjusted mean) during which the platelet count was 50,000/μL or more was 21.09 days. Adverse drug reactions were reported in 8.3% of patients in the lusutrombopag group and 2.1% of patients in the placebo group. Two patients (1 per group) had a thrombotic event, but neither were associated with an excessive increase in platelet count (200,000/μL or more).In a placebo-controlled trial, lusutrombopag was effective in achieving and maintaining the target platelet count in patients with chronic liver disease and thrombocytopenia undergoing invasive procedures. No significant safety concerns were raised. Japanese clinical trial registration no: JapicCTI-132323.

To the best of our knowledge, none of the prognostic staging systems for hepatocellular carcinoma (HCC) patients who underwent sorafenib therapy is universally adopted or preferred. In the present study, we aimed to compare prognostic ability among five prognostic systems, including the Japan Integrated Staging (JIS) system, the Barcelona Clinic Liver Cancer classification system, the tumor-node-metastasis classification system, the Cancer of the Liver Italian Program scoring system and the Chinese University Prognostic Index (CUPI) scoring system for HCC patients who received sorafenib therapy. A total of 143 HCC patients treated with sorafenib were analysed. We compared prognostic ability among the five prognostic systems using the likelihood ratio (LR) χ2 test, linear trend χ2 test and concordance index (c-index). Our cohort included 114 men and 29 women. The median patient age was 71 years (range, 45–89 years). A total of 102 patients were classified as Child-Pugh A and 41 as Child-Pugh B, whereas 31 patients (21.7%) had portal vein invasion and 63 (44.1%) extrahepatic metastases. The median survival time was 6.9 months. In the LR χ2 test, the CUPI scoring system had the highest value (35.804), followed by the JIS system (17.469). In the linear trend χ2 test, the CUPI scoring system had the highest value (17.523), followed by the JIS system (15.819). In addition, the JIS system had the highest value in the 6-month c-index (0.659) as well as in the 1-year c-index (0.674). However, the CUPI classification system had the lowest value in the 1-year c-index (0.590). In conclusion, the JIS system may be an appropriate staging system for HCC patients undergoing sorafenib therapy.

Patient: Female, 68 Final Diagnosis: Myelodysplastic Syndrome with Intestinal Behçet’s Disease-Like Symptoms Symptoms: Abdominal pain • fever • oral ulcer Medication: — Clinical Procedure: CT • bone marrow examination • colonoscopy Specialty: Hematology Objective: Rare disease Background: Intestinal Behçet’s disease-like symptoms are rare complications of myelodysplastic syndrome and are often refractory to immunosuppressive therapies. We described a case of myelodysplastic syndrome complicated by Behçet’s disease-like symptoms treated with prednisolone and azacitidine. Case Report: A 68-year-old Japanese woman was admitted to our hospital because of persistent high fever and lower abdominal pain. Oral ulcerations developed after admission, and multiple ulcers were found in her terminal ileum by endoscopic examination. She was diagnosed with myelodysplastic syndrome with trisomy 8 by bone marrow examination. Her symptoms diminished after administration of prednisolone, but relapsed afterwards. She began azacitidine therapy and her symptoms have been controlled for at least 10 months. Conclusions: This case might suggest the possibility of azacitidine as a treatment option for myelodysplastic syndrome complicated by Behçet’s disease-like symptoms.

The multi-kinase inhibitor sorafenib is now used as standard therapy for advanced hepatocellular carcinoma (HCC). Predictive biomarkers of response to sorafenib are thus necessary. The purpose of this study was to assess the feasibility of using targeted DNA and RNA sequencing to elucidate candidate biomarkers of sorafenib response using fine-needle biopsy, formalin-fixed paraffin-embedded (FFPE) specimens in patients with HCC. Targeted DNA and RNA deep sequencing were feasible for the evaluation of fine-needle biopsy FFPE specimens obtained from 46 patients with HCC treated with sorafenib. Frequent mutations of suppressor genes, such as CTNNB1 (34.8%) and TP53 (26.1%), were detected in the HCC tumors. After excluding these suppressor genes, the average numbers of detected oncogene mutations differed significantly between the non-PD and PD groups (P = 0.0446). This result suggests that the oncogene mutational burden in the tumor might be associated with the clinical response to sorafenib. We have identified candidate gene expression (TGFa, PECAM1, and NRG1) in tumor for the prediction of sorafenib response and PFS by RNA sequencing. Our findings provide new insights into biomarkers for sorafenib therapy and allow us to discuss future therapeutic strategies.

The significance of gastric xanthelasma in relation to gastric cancer still remains unclear. We investigated whether gastric xanthelasma would be a useful marker for predicting the development of early gastric cancer. A total of 1823 patients who underwent a medical health checkup were enrolled. We examined the relationship between gastric xanthelasma and various clinical features, and in an endoscopic follow-up study investigated whether the presence of gastric xanthelasma was predictive of the development of early gastric cancer. In the initial endoscopic examination, gastric xanthelasma was detected in 107 (5.9 %) of the 1823 patients. The presence of gastric xanthelasma was significantly associated with age ≥65 years, male gender, open-type atrophy, and the presence of diabetes mellitus (DM) (p

The present study examined the prognostic ability of our proposed performance status combined Japan Integrated Staging (PS-JIS) system in hepatocellular carcinoma (HCC) patients with liver cirrhosis (LC) comparing with other four prognostic systems including original JIS system, the Barcelona Clinic Liver Cancer classification system, TNM classification system and the Cancer of the Liver Italian Program (CLIP) scoring system. A total of 1,170 HCC patients complicated with LC were analysed. The disease was staged for all analysed patients by means of the five staging systems. The cumulative overall survival (OS) rate was calculated by Kaplan-Meier method and tested by log-rank test. We also examined prognostic factors associated with OS using univariate and multivariate analyses and compared the prognostic ability in each prognostic system using concordance index (c-index) at 1-, 3- and 5-year time-points. Overall significance in each prognostic system was P

AIM There have been no established predictors of the outcome on sorafenib therapy for hepatocellular carcinoma (HCC) patients. We aimed to establish a new prognostic model suitable for sorafenib in HCC. METHODS Among 465 HCC patients treated with sorafenib in 14 hospitals, we formed a training cohort with 270 patients at seven hospitals located in West Japan and a validation cohort with 167 patients at seven hospitals located in East Japan. In the training cohort, we examined the relationship between overall survival (OS) and pretreatment clinical factors, and structured a new prognostic model. We verified this model in the validation cohort and compared with four existing staging models. RESULTS Multivariate analysis demonstrated distant metastases, portal invasion, intrahepatic tumor burden of more than 50%, serum α-fetoprotein of 150 ng/dL or more, des-γ-carboxyprothrombin of 1200 mAU/mL or more, albumin of 3.5 g/dL or less and total bilirubin of more than 1.0 mg/dL were significant independent adverse prognostic factors. We calculated a Japan Red Cross (JRC) score with these factors and classified three groups: low-, intermediate- or high-risk. Their median OS were well stratified (18.0, 8.8 and 3.7 months, respectively, P

Background and aim This study aimed to elucidate whether interferon (IFN)-free direct-acting antiviral (DAA) therapy for hepatitis C after curative treatment of hepatocellular carcinoma (HCC) promotes HCC recurrence in a real-world large-scale cohort. Methods This multicenter study was conducted by the Japanese Red Cross Hospital Liver Study Group. This retrospective study analyzed 516 patients who underwent antiviral treatment for hepatitis C with either IFN (n = 148) or IFN-free DAA (n = 368) after curative HCC treatment; 78 IFN-treated patients and 347 IFN-free DAA-treated patients achieved sustained virological response (SVR). The recurrence rate of HCC was compared between the antiviral therapies. Logistic analysis and Cox proportional hazards analysis identified factors associated with early recurrence of HCC within 24 weeks of antiviral therapy and recurrence throughout the observation period, respectively. Results AFP at the completion of antiviral therapy, clinical stage of HCC, and non-SVR were independent factors associated with early recurrence of HCC. Among patients who had achieved SVR, the clinical stage of HCC and the level of AFP at completion of antiviral therapy were independent factors associated with early recurrence of HCC. For recurrence throughout the observation period in SVR patients, AFP at completion of antiviral therapy, duration between last HCC treatment to antiviral therapy, and the number of treatments were independent factors. There was no significant difference in the rate of early recurrence of HCC or recurrence throughout the observation period between IFN and IFN-free DAA treated patients. Conclusions There were no differences in the early recurrence rate of HCC between patients who underwent IFN and those who underwent IFN-free DAA as antiviral therapies.

Background and aims: We aimed to investigate the effect of serum sodium level on survival in hepatocellular carcinoma (HCC) patients complicating with liver cirrhosis (LC). Methods: A total of 1170 HCC patients with LC were analysed. We classified these patients into three groups according to serum sodium level at HCC diagnosis: group A (n=96); serum sodium ≤135 mmol/L, group B (n=520); 135 mmol/L < serum sodium ≤140 mmol/L, group C (n=554); serum sodium >140 mmol/L. We compared the baseline characteristics and overall survival (OS) among these three groups. Furthermore, we examined the factors linked to OS using univariate and multivariate analyses. Results: In our results, decreased baseline serum sodium level was significantly associated with Child-Pugh classification and HCC stage along with several laboratory parameters in groups A, B and C. The median follow-up period was 1.1 years in group A, 2.4 years in group B and 3.3 years in group C. The 1-, 3- and 5-year cumulative OS rates in groups A, B and C were 64.8%, 46.9% and 25.7%, respectively, in group A, 85.5%, 60.5% and 41.1%, respectively, in group B and 90.7%, 66.6% and 48.2%, respectively, in group C (P

Background and study aims Cold snare polypectomy (CSP) for small colorectal polyps has lower incidence of adverse events, especially delayed postpolypectomy bleeding (DPPB). However, few data are available on comparisons of the incidence of DPPB of CSP and hot polypectomy (HP). The aim of this study was to evaluate the incidence of DPPB after CSP and compare it with that of HP. A propensity score model was used as a secondary analysis. Patients and methods This was a retrospective cohort study conducted in a single municipal hospital. We identified 539 patients with colorectal polyps from 2 mm to 11 mm in size who underwent CSP (804 polyps in 330 patients) or HP (530 polyps in 209 patients) between July 2013 and June 2015. Results There were no cases of DPPB in the CSP group. Conversely, DPPB occurred in 4 patients (1.9 %) after HP, resulting in a significant difference between the CSP and HP groups (0.008 % vs 0 %, P = 0.02). Propensity score-matching analysis created 402 matched pairs, yielding a significantly higher DPPB rate in the HP group than CSP group (0.02 % vs 0 %, P = 0.04). However, significantly more patients in the CSP group had unclear horizontal margins that precluded assessment (83 vs 38 cases, P Conclusions DPPB was less frequent with CSP than HP, as selected by the propensity score-matching model. Our findings indicate that CSP is recommended polypectomy in daily clinical setting. However, special care should be taken during polyp retrieval and horizontal margin assessment, and these issues could be taken into account in follow-up after CSP.

Aim Portal vein thrombosis (PVT) is one of the most critical disorders in liver disease patients. These patients have the imbalance of coagulation and coagulation inhibition resulting from decreased levels of coagulation inhibitory factors, such as protein C, protein S, and antithrombin III (AT-III). We designed this randomized, double-blind, placebo-controlled trial comparing the safety and efficacy of AT-III for PVT in liver disease patients with those who received no treatment. Methods Eligible patients were diagnosed with the association of thrombus, without tumor thrombus, and thrombus in more than 50% of the cross-sectional lumen of the portal vein. Patients with 70% or less serum level of AT-III were included. The study drug was given up to three times in a 5-day consecutive infusion interval if the thrombus decreased in size. Efficacy was evaluated by contrast enhanced computed tomography using a five-grade scale (complete response, partial response, slight response, no response, and progression). From October 2014 through to March 2016, 36 patients were randomly assigned to the AT-III group and 37 patients to the placebo group. Results The proportion of patients with complete response or partial response of PVT was significantly higher in the AT-III group (55.6%; 20/36 patients; 95% confidence interval, 38.1–72.1) than in the placebo group (19.4%; 7/36 patients, 95% confidence interval, 8.2–36.0) (P = 0.003). The overall incidence of adverse events and adverse drug reactions did not differ significantly between the two groups. Conclusion Antithrombin III is one of the essential therapies for patients with PVT in cases with lower concentration levels of AT-III.

We aimed to examine the relationship between the preoperative GSA index [uptake ratio of the liver to the liver plus heart at 15 min (LHL15) to uptake ratio of the heart at 15 min to that at 3 min (HH15) ratio] calculated from 99mTc‑labeled diethylene triamine pentaacetate-galactosyl human serum albumin (99mTc-GSA) scintigraphy and background liver fibrosis and to investigate whether the GSA index can be a useful predictor in hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC) patients treated with surgical resection (SR). A total of 213 HCV-related HCC patients were analyzed. Receiver operating characteristic (ROC) curve analysis was performed for calculating the area under the ROC (AUROC) for nine noninvasive parameters including GSA index, indocyanine green retention at 15 min, aspartate aminotransferase (AST) to platelet ratio index, FIB-4 index, AST to alanine aminotransferase ratio, serum albumin, total bilirubin, platelet count and prothrombin time for cirrhosis. We also examined predictive factors associated with overall survival (OS) and recurrence-free survival (RFS) after SR in univariate and multivariate analyses. There were 153 males and 60 females with the mean age of 69.9 years. The median observation periods were 2.8 years. The mean maximum tumor size was 4.1 cm. HH15 ranged from 0.452 to 0.897. LHL15 ranged from 0.669 to 0.982. The mean value of the GSA index was 1.41. Among the nine parameters, the GSA index yielded the highest AUROC for cirrhosis with a level of 0.786 at an optimal cut-off value of 1.37 (sensitivity, 65.9%; specificity, 79.0%). In multivariate analyses, the GSA index was an independent predictor (P

Aim Some patients develop hepatocellular carcinoma (HCC) during nucleoside/nucleotide analog (NA) therapy even if alanine aminotransferase (ALT) or hepatitis B virus (HBV) DNA levels are sufficiently reduced. The aim of this study is to identify the risk factors of development of HCC during NA therapy. Methods Six hundred and two patients were analyzed who were continuously receiving NA for chronic HBV infection. The patients who developed HCC previously or within 1 year of therapy were excluded. In the patients studied, the median duration of therapy was 90 months. A total of 492 patients had chronic hepatitis (CH) and 110 had liver cirrhosis (LC). Results In 602 patients, the rate of normalization of ALT, loss of serum HBV DNA and development of HCC were 90.4%, 55.4%, and 6.1%, respectively. The significant risk factors of development of HCC were LC status and duration of therapy. The annual incidence of HCC in LC patients was 2.53%/year, compared with 0.34%/year in CH patients. When the relation between the incidence of HCC and the response to therapy was evaluated, in patients with normalization of ALT level, loss of HBV DNA by real-time polymerase chain reaction or hepatitis B e-antigen seroconversion, the incidences of HCC was reduced to some extent. However, none of the patients who achieved hepatitis B surface antigen (HBsAg) seroclearance during NA therapy developed HCC. Conclusion LC status was the significant risk factor of development of HCC during NA therapy. However, none of the patients who showed HBsAg seroclearance developed HCC. The ultimate goal of therapy for reduced risk of HCC may be HBsAg seroclearance.

The aims of the present study were to examine the relationship between the preoperative FIB-4 index and background liver fibrosis in non-tumor parts obtained from surgical specimens and to investigate whether the FIB-4 index can be a useful predictor for non-B non-C hepatocellular carcinoma (NBNC-HCC) patients treated with surgical resection (SR). A total of 118 patients with NBNC-HCC treated with SR with curative intent were analyzed. Receiver operating characteristic (ROC) curve analysis was performed for calculating the area under the ROC (AUROC) for the FIB-4 index, aspartate aminotransferase (AST) to platelet ratio index, AST to alanine aminotransferase ratio, serum albumin, total bilirubin and platelet count for cirrhosis. We also examined predictors linked to overall survival (OS) and recurrence-free survival (RFS) after SR. The mean patient age was 68.9±9.0 years (93 males and 25 females) with a median observation period of 3.2 years. In extracted surgical specimens, background liver cirrhosis (F4) was observed in 39 patients (33.1%). The mean maximum tumor size was 5.7±3.2 cm. The mean body mass index was 24.3±3.9 kg/m2. The FIB-4 index yielded the highest AUROC for cirrhosis with a level of 0.887 at an optimal cut-off value of 2.97 (sensitivity, 92.3; specificity, 69.6%). In the multivariate analysis, serum α-fetoprotein >40 ng/ml (P=0.026) was the only significant independent predictor linked to OS, while tumor number (P=0.002) and FIB-4 index >2.97 (P=0.044) were significant factors linked to RFS. In conclusion, preoperative FIB-4 index can be a useful predictor for NBNC-HCC patients who undergo SR.

The significance of diabetes mellitus (DM) in gastric carcinogenesis still remains unclear. We investigated whether DM would be a risk factor for the development of early gastric cancer.Factors related to the presence of gastric cancer were examined in patients undergoing medical health checkups. We then investigated whether DM was related to the development of early gastric cancer during an endoscopic follow-up study.Gastric cancer was detected in 14 (1.0%) of 1463 patients at the first endoscopic examination and was significantly associated with the severity of gastric atrophy and the presence of DM. During the follow-up period (range 36-108 months; mean 70.0 months), early gastric cancer was newly detected in 26 (1.8%) of the 1449 patients in whom gastric cancer had not been detected at the first examination. Gastric cancer was detected in 17 (1.3%) of 1301 patients without DM, and in 9 (6.1%) of 148 patients with DM (P0.0001). Multivariate analyses demonstrated that open-type gastric atrophy and DM were independently related to the development of early gastric cancer (P0.0001 and P = 0.020, respectively). Gastric cancer was identified in 14 (5.1%) of 274 patients who had open-type atrophic gastritis without DM, whereas it was identified in 8 (16.0%) of 50 patients who had both open-type atrophic gastritis and DM (P = 0.0042).DM increases the risk of early gastric cancer development.

Hepatocellular carcinoma (HCC) is one of the most common causes of cancer-related mortality worldwide. In the last few decades, there has been a marked increase in therapeutic options for HCC and epidemiological characteristics at HCC diagnosis have also significantly changed. With these changes and advances in medical technology and surveillance program for detecting earlier stage HCC, survival in patients with HCC has significantly improved. Especially, patients with liver cirrhosis are at high risk of HCC development, and regular surveillance could enable early detection of HCC and curative therapy, with potentially improved clinical outcome. However, unfortunately, only 20% of HCC patients are amenable to curative therapy (liver transplantation, surgical resection or ablative therapies). Locoregional therapies such as radiofrequency ablation, percutaneous ethanol injection, microwave coagulation therapy and transcatheter arterial chemoembolization play a key role in the management of unresectable HCC. Currently, molecular-targeted agents such as sorafenib have emerged as a promising therapy for advanced HCC. The choice of the treatment modality depends on the size of the tumor, tumor location, anatomical considerations, number of tumors present and liver function. Furthermore, new promising therapies such as gene therapy and immunotherapy for HCC have emerged. Approaches to the HCC diagnosis and adequate management for patients with HCC are improving survival. Herein, we review changes of epidemiological characteristics, prognosis and therapies for HCC and refer to current knowledge for this malignancy based on our experience of approximately 4000 HCC cases over the last three decades.

We examined whether supplementation of branched-chain amino acid (BCAA) granules in an early stage of underlying liver disease (pretreatment serum albumin levels ≥ 3.6 g/dl) can improve overall survival (OS) after therapy for hepatocellular carcinoma (HCC) using propensity score matching analysis. We compared OS between patients treated with BCAA granules and control group patients in two propensity score matched cohorts (cohort 1: pretreatment serum albumin levels ≥ 3.6 g/dl and

Background & Aims There have been no established predictive factors of responders to sorafenib in patients with unresectable hepatocellular carcinoma (HCC). This study aimed to investigate the factors predicting a good response to sorafenib in Japanese patients with HCC. Methods A total of 465 patients with unresectable HCC in the Japanese Red Cross Liver Study Group were treated with sorafenib between January 2008 and August 2013, and 316 patients with sufficient clinical data were analysed. To determine the factors predicting a good response, the relationships between radiological response and the following clinicopathological factors were analysed: age, gender, performance status, liver function, tumour status and decrease in serum alpha-foetoprotein (AFP) level after 1 month. Results This study included 259 males and 57 females with a median age of 70 years (range, 37–90 years), of which 191 (60.4%) were classified as Barcelona Clinic Liver Cancer stage C, and 271 (85.8%) had Child-Pugh class A liver function. The median overall survival time was 307 days and progression-free survival time was 109 days. According to the modified Response Evaluation Criteria In Solid Tumours, four patients achieved a complete response, 51 achieved a partial response, 136 had stable disease and 125 had progressive disease. Multivariate analysis identified female gender (P = 0.003) and decreased serum AFP level after 1 month (P = 0.042) as independent predictors of a complete or partial response. Conclusion Our results suggest female gender and a decrease in serum AFP level are independent predictors of good response to sorafenib.

Background and aims: We aimed to compare clinical outcomes and safety after sorafenib therapy between patients with Barcelona Clinic Liver Cancer (BCLC) stage B or C hepatocellular carcinoma (HCC) aged ≥75 years (aged group, n=179) and those with BCLC stage B or C HCC aged 0.999). Objective response rates were 15.1% (27/179) in the aged group and 14.3% (40/279) in the control group (P=0.892). Treatment related SAEs of grade 3 or more were observed in 51 patients (28.5%) in the aged group and in 69 patients (24.7%) in the control group (P=0.385). In the propensity score matched cohort (132 pairs), no significant difference in the two groups was observed in terms of OS (P=0.898) and PFS (P=0.407). Conclusion: In BCLC stage B or C HCC patients treated with sorafenib, life expectancy, disease progression, treatment efficacy and SAEs are unaffected by age over 75 years.
