Controlling adverse events (AEs) through dose reduction can enhance drug adherence and treatment response. Currently, there is no guide for sorafenib dosing. The aim of this study was to evaluate whether sorafenib dosing could affect treatment outcomes. A total of 782 hepatocellular carcinoma (HCC) patients treated with sorafenib were evaluated for sorafenib dosing and its modifications via medical records at baseline and regular follow-up. Study outcomes included progression-free survival (PFS), overall survival (OS), sorafenib duration, cumulative dose, AEs and drug discontinuation. The median patient survival was 7.7 months. Overall, 242 (30.9%) patients underwent dose reduction and 121 (17.5%) discontinued sorafenib due to AEs. In multivariate analysis, dose reduction was identified to be independently predictive of PFS and OS. The 800-to-400 mg/day group provided significantly better PFS than the 800 mg/day-maintained group or the 800-to-600 mg/day group. Likewise, the 800-to-400 mg/day group resulted in a significantly better OS than other dosing. However, dose reduction to 200 mg/day led to significantly worse PFS and OS. Hand-foot skin reaction and drug discontinuation due to AEs were higher in the 800-to-600 mg/day group than the 800-to-400 mg/day group. The 800-to-400 mg/day group had significantly longer treatment duration and higher cumulative dose than the 800 mg/day-maintained group. Sorafenib dose reduction can improve HCC survival and increase patient tolerance and adherence coupled with longer duration and higher cumulative dose. Dose reduction from 800 to 400 mg/day than to 600 mg/day is recommended when clinically warranted. However, dose reduction to 200 mg/day is not recommendable.

Background A real-life study is essential outside clinical trials. The aim is to evaluate the clinical outcomes of direct acting agents (DAA) for patients with chronic hepatitis C (CHC) in real practice. Methods We analyzed 590 consecutively enrolled patients with CHC-1b who received DAAs since 2015, when DAAs were introduced in Korea. The patients were checked for resistance-associated variants (RAV) against nonstructural protein 5A inhibitors and then daclatasvir/asunaprevir or sofosbuvir based regimens were chosen. Results The frequency of patients with cirrhosis and prior hepatocellular carcinoma (HCC) was 29.2% and 4.7%, respectively. For the RAV test, 10% were positive and in 3.6% the result was "indeterminate." Overall, 518 patients were treated with a 24-week regimen of daclatasvir/asunaprevir, 72 patients (RAV positive 75%) were treated with 12 weeks regimen of ledipasvir/sofosbuvir or daclatasvir/sofosbuvir. The SVR12 was 94.0% in the daclatasvir/asunaprevir, 98.2% in the ledipasvir/sofosbuvir, and 100% in the daclatasvir/sofosbuvir group. A total of 93.3% of SVR12 in the RAV-"indeterminate" patients was not difference 95.0% in the RAV-negative patients. Up to 1 year, de novo HCC occurrence and recurrence developed in 2.6% and 17.8%, respectively. HCC was more frequent in cirrhotic patients than in noncirrhotic patients (P = 0.000). α Fetoprotein (AFP) level at the end of treatment was a predicting factor for de novo HCC. Conclusions Optimizing the choice of DAAs according to RAV test resulted in high SVR among CHC-1b Korean patients. This real practice multicenter cohort study suggests the importance of AFP and HCC surveillance in cirrhotic patients even after successful HCV therapy.

Patients with chronic hepatitis C who achieve a sustained viral response after pegylated interferon therapy have a reduced risk of hepatocellular carcinoma, but the risk after treatment with direct-acting antivirals is unclear. We compared the rates of early development of hepatocellular carcinoma after direct-acting antivirals and after pegylated interferon therapy. We retrospectively analysed 785 patients with chronic hepatitis C who had no history of hepatocellular carcinoma (211 treated with pegylated interferon, 574 with direct-acting antivirals) and were followed up for at least 24 weeks after antiviral treatment. De novo hepatocellular carcinoma developed in 6 of 574 patients receiving direct-acting antivirals and in 1 of 211 patients receiving pegylated interferon. The cumulative incidence of early hepatocellular carcinoma development did not differ between the treatment groups either for the whole cohort (1.05% vs 0.47%, P = .298) or for those patients with Child-Pugh Class A cirrhosis (3.73% vs 2.94%, P = .827). Multivariate analysis indicated that alpha-fetoprotein level >9.5 ng/mL at the time of end-of-treatment response was the only independent risk factor for early development of hepatocellular carcinoma in all patients (P < .0001, hazard ratio 176.174, 95% confidence interval 10.768-2882.473) and in patients treated with direct-acting agents (P < .0001, hazard ratio 128.402, 95% confidence interval 8.417-1958.680). In conclusion, the rate of early development of hepatocellular carcinoma did not differ between patients treated with pegylated interferon and those treated with direct-acting antivirals and was associated with the serum alpha-fetoprotein level at the time of end-of-treatment response.

Background and Aim The aim of this study was to validate the Chronic Liver Failure-Sequential Organ Failure Assessment score (CLIF-SOFAs), CLIF consortium organ failure score (CLIF-C OFs), CLIF-C acute-on-chronic liver failure score (CLIF-C ACLFs), and CLIF-C acute decompensation score (CLIF-C ADs) in Korean chronic liver disease patients with acute deterioration. Methods ACLF was defined by either the Asian Pacific Association for the Study of the Liver ACLF Research Consortium (AARC) or CLIF-C criteria. The diagnostic performances for short-term mortality were compared by the area under the receiver operating characteristics (AUROC) curve. Results Among a total of 1470 patients, 252 patients were diagnosed with ACLF according to the CLIF-C (197 patients) or AARC definition (95 patients). As the ACLF grades increased, the survival rates became significantly lower. The AUROCs of the CLIF-SOFAs, CLIF-C OFs and CLIF-C ACLFs were significantly higher than those of the Child-Pugh, Model for End-stage Liver Disease (MELD), and MELD-Na scores in ACLF patients according to the CLIF-C definition (all P

BACKGROUND AND AIM There are limited data assessing whether patients who achieved virological suppression on lamivudine but remain hepatitis B "e" antigen-positive should be switched to a more potent antiviral with a high genetic barrier to resistance or continue with lamivudine. We compared the safety and efficacy of switching with entecavir versus continuing lamivudine. METHODS This was a Phase IV, randomized, open-label, prospective study in a tertiary care setting. Seventy-three chronic hepatitis B patients who achieved virological suppression on lamivudine (serum hepatitis B virus DNA

Summary Background Although transarterial chemotherapy is used to retard tumour progression for hepatocellular carcinoma (HCC) patients awaiting orthotopic liver transplantation (OLT), information regarding the acceptable waiting time and appropriate patient selection for the therapy is lacking. Aim To examine dropout times and determine the best candidates for pre-transplant transarterial therapy in a cohort study. Methods In total, 180 consecutive HCC candidates receiving pre-transplant chemo-lipiodolization were included in the study. Results Overall, 70 (38.9%) patients dropped off the waiting list during the median follow-up of 19 months. According to the Child–Pugh (C–P) classification, the estimated dropout rates at 1 and 2 years were 17.2% and 44.8% for the C–P A group and 33.4% and 81.3% for the C–P B/C group, respectively. C–P B/C patients experienced more frequent dropouts than C–P A patients (P 100 ng/mL, tumour size >3 cm and multiple nodules remained independently predictive of dropout for C–P A group (all P

Background and Aim: Studies from hepatitis B virus endemic areas have shown less durable lamivudine-induced responses and have raised issues about the management of a post-treatment relapse. Methods: From January 2000 to June 2004, all 51 patients (43 HBeAg-positive and eight HBeAg-negative) were retreated with lamivudine for at least 12 months. All had a post-treatment relapse after HBeAg responses (HBeAg loss/seroconversion) during the first therapy. Results: During retreatment, HBeAg seroconversion occurred more frequently in those patients with HBeAg seroconversion than in those with HBeAg loss alone during prior lamivudine therapy (P = 0.001). On multivariate analysis, prior HBeAg seroconversion and early virological response (EVR) (≤ 2 months of retreatment) independently predicted HBeAg seroconversion (P = 0.012 and P = 0.004, respectively). With regard to virological breakthrough, only the time to virological response (> 2 months of retreatment) remained significant (P = 0.048). Among the HBeAg-negative patients, virological breakthrough occurred in only one patient with a late virological response. Conclusions: EVR is a major predictor in determining a favorable response to lamivudine retreatment. Our observations suggest that lamivudine retreatment will provide more therapeutic gains in those patients with a prior HBeAg seroconversion than in those with HBeAg loss alone.

The new flat-panel display device was developed by using a thick film graphite powder as a cathode material. The simple screen printing process was performed to fabricate Planar Emitter Display (PED) devices. The basic structure of PED is of the diode type. The electrical and optical characteristics of PED were investigated to ascertain their suitability for application in display devices.
