ABSTRACT

Background/Aims@#The objective of this study was to determine whether the newly developed two-dimensional shear wave elastography (2D-SWE, RS85, Samsung-shearwave imaging) was more valid and reliable than transient elastography (TE) for predicting the stage of liver fibrosis. @*Methods@#The study prospectively enrolled a total of 116 patients with chronic liver disease who underwent 2D-SWE, TE, laboratory testing, and liver biopsy on the same day from two tertiary care hospitals. One patient with unreliable measurement was excluded. The measurement of 2D-SWE was considered acceptable when a homogenous color pattern in a region of interest of at least 10 mm was detected at 10 different sites. Diagnostic performance was calculated using area under the receiver operating characteristic curve (AUROC). @*Results@#Liver fibrosis stages included F0 (18%), F1 (19%), F2 (24%), F3 (22%), and F4 (17%). Interclass correlation coefficient for inter-observer agreement in 2D-SWE was 0.994 (95% confidence interval [CI], 0.988 to 0.997). Overall, the results of 2D-SWE and stages of histological fibrosis were significantly correlated (r = 0.601, p < 0.001). For The 2D-SWE showed good diagnostic ability (AUROC, 0.851; 95% CI, 0.773 to 0.911) comparable to TE (AUROC, 0.859; 95% CI, 0.781 to 0.916) for the diagnosis of significant fibrosis (≥ F2), and the cut-off value was 5.8 kPa. AUROC and optimal cut-off of 2D-SWE for the diagnosis of liver cirrhosis were 0.889 (95% CI, 0.817 to 0.940) and 9.6 kPa, respectively. TE showed similar diagnostic performance in distinguishing cirrhosis (AUROC, 0.938; 95% CI, 0.877 to 0.974; p = 0.08). @*Conclusions@#2D-SWE is comparable to TE in diagnosing significant fibrosis and liver cirrhosis with high reliability.

ABSTRACT

BACKGROUND/AIMS@#This study was conducted to clarify the sustained virological response (SVR) prediction ability of baseline and treatment-related factors in patients with chronic hepatitis C virus (HCV) infection.@*METHODS@#This retrospective study collected data at four tertiary referral hospitals between June 2004 and July 2012. Out of 476 patients, 330 treatment-naïve patients with chronic HCV infection were recruited. Pegylated interferon α-2a/-2b plus ribavirin was administered for either 24 or 48 weeks depending on the HCV genotype. The baseline and treatment-related predictive factors of SVR were evaluated by analyzing data measured before treatment (i.e., baseline) and during treatment.@*RESULTS@#SVR rates for genotypes 1 and 2 were 63% (97/154) and 79.5% (140/176), respectively (p = 0.001). Multivariate analysis for baseline factors revealed that young age (p = 0.009), genotype 2 (p = 0.001), HCV RNA level of 150 × 10³/µL (p 150 × 10³/µL. In multivariate analysis for treatment-related factors, SVR was associated with achievement of a rapid virological response (RVR; p < 0.001), treatment adherence of ≥ 80/80/80 (p < 0.001).@*CONCLUSIONS@#Young age, genotype 2, low HCV RNA level, RVR, and treatment adherence were significantly associated with SVR. In addition, platelet count was an independent predictive factor for SVR. Therefore, platelet count could be used to develop individualized treatment regimens and to optimize treatment outcomes in patients with chronic HCV infection.

ABSTRACT

BACKGROUND/AIMS@#Transarterial chemoembolization (TACE) is performed for single hepatocellular carcinoma (HCC) that are not eligible for surgery or ablation therapy. We investigated the clinical outcomes of patients with a single HCC ≤ 5 cm treated with TACE.@*METHODS@#This study analyzed 175 consecutive patients who underwent TACE as an initial treatment for single HCC ≤ 5 cm. Predictive factors for complete response (CR), recurrence after CR, and overall survival (OS) were evaluated.@*RESULTS@#Total 119 patients (68%) achieved CR after TACE. Tumor size 65 years and absence of liver cirrhosis were predictive factors for non-recurrence after CR (p < 0.05). The OS for all patients was 80.7 ± 5.6 months, and the 1-, 3-, and 5-year OS rates were 88.1%, 64.8%, and 49.9%, respectively. In multivariate analysis for OS, CR (hazard ratio [HR], 0.467; 95% confidence interval [CI], 0.292 to 0.747) and Child class A (HR, 0.390; 95% CI, 0.243 to 0.626) were significant factors. The OS for the CR and Child class A group were 92 and 93.6 months, respectively, and that of the non-CR and Child B, C group were 53.3 and 50.7 months, respectively (p < 0.001).@*CONCLUSIONS@#TACE can be a valid treatment in patients with a single HCC ≤ 5 cm not suitable for curative treatment, especially in patients with Child class A and CR after TACE.

ABSTRACT

BACKGROUND/AIMS: The aim of this study was to investigate parameters that predict radiation-induced liver disease (RILD) following stereotactic body radiotherapy (SBRT) in patients with hepatocellular carcinoma (HCC) and to identify the clinical significance of RILD. METHODS: We retrospectively reviewed the medical records of 117 HCC patients who were treated by SBRT from March 2011 to February 2015. RILD was defined as elevated liver transaminases more than five times the upper normal limit or a worsening of Child-Pugh (CP) score by 2 within 3 months after SBRT. All patients were assessed at 1 month and every 3 months after SBRT. RESULTS: Median follow-up was 22.5 months (range, 3 to 56) after SBRT. RILD was developed in 29 of the 117 patients (24.7%). On univariate analysis, significant predictive factors of RILD were pretreatment CP score (p < 0.001) and normal liver volume (p = 0.002). Multivariate analysis showed that CP score was a significant predictor of RILD (p < 0.001). The incidence of RILD increased above a CP score of 6 remarkably. The rate of recovery from RILD decreased significantly above a CP score of 8. Survival analysis showed that CP score was an independent prognostic factor of overall survival (p = 0.001). CONCLUSIONS: CP score is a significant factor to predict RILD in patients with chronic liver disease. RILD can be tolerated by patients with a CP score ≤ 7. However, careful monitoring of liver function is needed for patients with a CP score 7 after SBRT.

ABSTRACT

Hepatocellular carcinoma (HCC) is the 2nd most common cause of cancer related death in Korea and well-known malignancy with poor prognosis. Sorafenib is the first-line molecular targeted agent in patients with extra-hepatic spread of HCC. However, complete response is extremely rare in patients treated with sorafenib and the disease control rate is only 43%. We report a 53-year-old man with advanced HCC with pulmonary metastasis who showed complete response by cytotoxic chemotherapy with doxorubicin and cisplatin with relatively tolerable adverse effects after failure of treatment with sorafenib.

ABSTRACT

BACKGROUND/AIMS: To identify the usefulness of endoscopic ultrasonography with a mini-probe (EUM) and to create a predictive model for esophageal variceal (EV) recurrence and bleeding following esophageal variceal ligation (EVL). METHODS: A total of 144 patients who received EUM prior to prophylactic EVL and met the inclusion criteria were enrolled. EUM findings, EV diameter, paraesophageal vein diameter, and the number of perforating veins were assessed. RESULTS: EV recurrence was observed in 42 patients (29.2%), 10 of whom experienced EV bleeding. Larger diameter of the paraesophageal vein (odds ratio [OR], 1.51; 95% confidence interval [CI], 1.17 to 1.96; p=0.002) and perforating vein (OR, 3.27; 95% CI, 1.11 to 9.65; p=0.032) were significant predictive factors for EV recurrence. However, the diameter of the paraesophageal vein was the only significant risk factor for EV bleeding (adjusted OR, 1.51; 95% CI, 1.06 to 2.16; p=0.022). The areas under the curves of the predictive model for EV recurrence and bleeding were 0.872 (95% CI, 0.811 to 0.934) and 0.811 (95% CI, 0.630 to 0.992), respectively. CONCLUSIONS: The diameter of the paraesophageal vein was a significant predictive factor for EV recurrence and bleeding. The predictive model constructed based on the significant EUM findings exhibited good performance.

ABSTRACT

BACKGROUND/AIMS: To investigate the predictive factors for complete response (CR) and recurrence after CR in patients with hepatocellular carcinoma (HCC) treated with transarterial chemoembolization (TACE). METHODS: Among 691 newly diagnosed HCC patients, 287 were treated with TACE as a first therapy. We analyzed the predictive factors for CR, recurrence after CR, and overall survival (OS). RESULTS: Eighty-one patients (28.2%) achieved CR after TACE, and recurrence after CR was detected in 35 patients (43.2%). In multivariate analyses, tumor size (≤5 cm) and single nodularity were predictive factors for CR, with hazard ratios (HRs) of 0.35 (p=0.002) and 0.41 (p20 ng/mL) level and multinodularity exhibited significant relationships with recurrence after CR, with HRs of 2.220 (p=0.026) and 3.887 (p5 cm), multinodularity, elevated serum AFP (>20 ng/mL) level, Child-Turcotte-Pugh score (B and C), and portal vein thrombosis were significant factors for OS. CONCLUSIONS: In patients treated with TACE as a first therapy, tumor size (≤5 cm) and single nodularity were predictive factors for CR, and multinodularity and elevated serum AFP (>20 ng/mL) levels were predictive factors for recurrence after CR. These factors were also significant for OS.

ABSTRACT

BACKGROUND/AIMS: Deficiencies of 25-hydroxyvitamin D (25(OH)D) are prevalent in patients with chronic liver disease (CLD). Liver fibrosis is the main determinant of CLD prognosis. The present study was performed to evaluate the correlation between 25(OH)D levels and liver fibrosis as assessed by transient elastography (TE) in patients with compensated CLD. METHODS: Serum 25(OH)D levels and liver stiffness were determined in a total of 207 patients who were subjected to the following exclusion criteria: patients with decompensated CLD; patients who had malignancies; patients who were taking medications; and patients who were pregnant. RESULTS: The most common etiology was chronic hepatitis B (53.1%). Advanced liver fibrosis (defined by TE [≥9.5 kPa]) was present in 75 patients (36.2%). There was a significant correlation between 25(OH)D deficiency and liver stiffness. Based on the multivariate analysis, the following factors were independently associated with advanced liver fibrosis: 25(OH)D deficiency (odds ratio [OR], 3.46; p=0.004), diabetes mellitus (OR, 3.04; p=0.041), and fibrosis-4 index (OR, 2.01; p<0.001). CONCLUSIONS: Patients with compensated CLD exhibit a close correlation between vitamin D level and liver stiffness as assessed by TE. Vitamin D deficiency was independently associated with advanced liver fibrosis.

ABSTRACT

Intervention treatment such as balloon retrograde or anterograde transvenous obliteration has been used for management of refractory hepatic encephalopathy as well as gastric variceal bleeding. Recently, plug-assisted retrograde transvenous obliteration without a help of balloon was newly developed to treat these patients. Here, we report three cases suffering refractory hepatic encephalopathy who were treated with this new technique.

ABSTRACT

Hepatocellular carcinoma (HCC) is well known malignancy with poor prognosis, even after resection of the primary tumor. Sorafenib is the first-line treatment in advanced HCC, but the disease control rate of sorafenib is only 43%. Pulmonary metastasectomy in patients with pulmonary metastasis from HCC has been reported to increase long-term survival compared with systemic chemotherapy. Video-assisted thoracic surgery is considered a reliable approach to the diagnosis and treatment of pulmonary diseases with low complication rate. Pulmonary metastasectomy is not universally accepted because of frequent local recurrence, an uncontrollable primary tumor, and frequent multiple pulmonary metastases in HCC, but outcome of pulmonary metastasectomy and adjuvant sorafenib therapy has not been studied. We experienced a patient who had advanced HCC with pulmonary oligometastasis and received surgical resection of the metastatic pulmonary nodule and sorafenib chemotherapy. In advanced HCC with pulmonary oligometastasis, surgical resection of pulmonary metastasis and sorafenib chemotherapy should be considered.

ABSTRACT

BACKGROUND/AIMS: The optimal timing for discontinuing oral antiviral therapy in patients with HBeAg-positive chronic hepatitis B (CHB) is unclear. The aim of our study was to investigate sustained remission after stopping antiviral therapy in patients with HBeAg-positive CHB. METHODS: We analyzed the medical records of 58 patients who were HBeAg-positive and had discontinued antiviral therapy. Antiviral therapy was discontinued after HBeAg seroconversion and HBV DNA negativity for 6-12 months with consolidation therapy. Virologic relapse was defined as an increase in serum HBV DNA >2,000 IU/mL. RESULTS: No difference was observed between the virologic non-relapse and virologic relapse groups in baseline HBV DNA level (p=0.441) or duration of seroconversion (p=0.070). Time-to-undetectable HBV DNA during treatment was shorter in the virologic non-relapse group (29 patients) compared to the relapse group (29 patients) (4.9+/-2.6 vs. 13.2+/-12.7 months; p or =18 months, p=0.020) and early virologic response (HBV DNA <20 IU/mL) at six months during antiviral therapy (p=0.017) were significant predictors for sustained remission. CONCLUSIONS: A consolidation period of at least 18 months and early virological response at six months during antiviral therapy were associated with sustained remission in patients with HBeAg-positive CHB after treatment.

ABSTRACT

BACKGROUND/AIMS: To investigate the association between the baseline profiles and dynamics of hepatitis B virus (HBV) DNA polymerase gene mutations and the long-term virological response of lamivudine (LAM)-adefovir (ADV) combination therapy in patients with LAM-resistant chronic hepatitis B. METHODS: Seventy-five patients who received LAM-ADV combination therapy for more than 12 months were analyzed. Restriction fragment mass polymorphism assays were used to detect and monitor the dynamics of LAM- and ADV-resistant mutations. RESULTS: The median duration of LAM-ADV combination therapy was 26 months (range, 12 to 58 months). The baseline mutation profiles, rtM204I (p=0.992), rtM204I/V (p=0.177), and rtL180M (p=0.051), were not correlated with the cumulative virological response, and the baseline HBV DNA level (p=0.032) was the only independent predictive factor for cumulative virological response. Tests for LAM- and ADV-resistant mutations were performed in 12 suboptimal responders in weeks 48 and 96. The population of rtM204 mutants persisted or increased in 8 of 12 patients, and rtA181T mutants newly emerged as a minor population in four patients until 96 weeks. Nevertheless, the viral loads progressively decreased during rescue therapy, and these dynamics did not correlate with virological response. CONCLUSIONS: The baseline profile and dynamics of LAM-resistant mutations during LAM-ADV combination therapy are not associated with a virological response.

ABSTRACT

Drug-induced liver injury (DILI) is an increasingly common cause of acute hepatitis. We examined clinical features and types of liver injury of 65 affected patients who underwent liver biopsy according DILI etiology. The major causes of DILI were the use of herbal medications (43.2%), prescribed medications (21.6%), and traditional therapeutic preparations and dietary supplements (35%). DILI from herbal medications, traditional therapeutic preparations, and dietary supplements was associated with higher elevations in aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels than was DILI from prescription medications. The types of liver injury based on the R ratio were hepatocellular (67.7%), mixed (10.8%), and cholestatic (21.5%). Herbal medications and traditional therapeutic preparations were more commonly associated with hepatocellular liver injury than were prescription medications (P = 0.002). Herbal medications and traditional therapeutic preparations induce more hepatocellular DILI and increased elevations in AST and ALT than prescribed medications.

ABSTRACT

BACKGROUND/AIMS: 18F-Fluorodeoxyglucose positron-emission tomography (18F-FDG PET) has been used to assess the biological behavior of hepatocellular carcinoma (HCC). In this study, we investigated the usefulness of 18F-FDG PET for predicting tumor progression and survival in patients with intermediate Barcelona Clinic Liver Cancer (BCLC) intermediate-stage HCC treated by transarterial chemoembolization (TACE). METHODS: From February 2006 to March 2013, 210 patients treated with TACE, including 77 patients with BCLC intermediate-stage HCC, underwent examination by 18F-FDG PET. 18F-FDG uptake was calculated based on the tumor maximum (Tmax) standardized uptake value (SUV), the liver mean (Lmean) SUV, and the ratio of the Tmax SUV to the Lmean SUV (Tmax/Lmean). RESULTS: The mean follow-up period for the 77 patients (52 males, 25 females; average age, 63.3 years) was 22.2 months. The median time to progression of HCC in patients with a low Tmax/Lmean ( or = 1.83) was 17 and 6 months, respectively (p < 0.001). The median overall survival time of patients with a low and high Tmax/Lmean was 44 and 14 months, respectively (p = 0.003). Multivariate analysis revealed that the Tmax/Lmean was an independent predictor of overall survival (hazard ratio [HR], 1.96; 95% confidence interval [CI], 1.210 to 3.156; p = 0.006) and tumor progression (HR, 2.05; 95% CI, 1.264 to 3.308; p = 0.004). CONCLUSIONS: 18F-FDG uptake calculated by the Tmax/Lmean using PET predicted tumor progression and survival in patients with BCLC intermediate-stage HCC treated by TACE.

ABSTRACT

BACKGROUND/AIMS: The predictive role of contrast-enhanced ultrasonography (CEUS) before performing transarterial chemoembolization (TACE) has not been determined. We assessed the possible predictive factors of CEUS for the response to TACE. METHODS: Seventeen patients with 18 hepatocellular carcinoma (HCC) underwent TACE. All of the tumors were studied with CEUS before TACE using a second-generation ultrasound contrast agent (SonoVue(R), Bracco, Milan, Italy). The tumor response to TACE was classified with a score between 1 and 4 according to the remaining enhancing-tumor percentage based on modified response evaluation criteria in solid tumors (mRECIST): 1, enhancing tumor or =75%). A score of 1 was defined as a "good response" to TACE. The predictive factors for the response to TACE were evaluated during CEUS based on the maximum tumor diameter, initial arterial enhancing time, arterial enhancing duration, intensity of arterial enhancement, presence of a hypoenhanced pattern, and the feeding artery to the tumor. RESULTS: The median tumor size was 3.1 cm. The distribution of tumor response scores after TACE in all tumors was as follows: 1, n=11; 2, n=4; 3, n=2; and 4, n=1. Fifteen tumors showed feeding arteries. The presence of a feeding artery and the tumor size (< or =5 cm) were the predictive factors for a good response (P=0.043 and P=0.047, respectively). CONCLUSIONS: The presence of a feeding artery and a tumor size of less than 5 cm were the predictive factors for a good response of HCC to TACE on CEUS.

ABSTRACT

Transcatheter arterial chemoembolization (TACE) is suitable treatment method of hepatocellular carcinoma (HCC) for patients with decreased underlying liver function or unresectable disease. But this procedure can induce some embolic events. We report a case of a gallbladder infarction caused by the embolic event in TACE procedure. A 61-year-old man had been going to undergo 6th TACE for marginal recurrence of HCC. After the procedure, gallbladder infarction occurred and was detected by abdominal computed tomography (CT) scan for response evaluation of the treatment at out-patient-clinic. Then, he was treated with oral antibiotics and conservative therapy at out-patient clinic. In 6th week after the event, abdominal CT scan showed improved state of gallbladder.

ABSTRACT

For a small hepatocellular carcinoma (HCC), liver resection shows most favorable outcome in case which liver transplantation is not available, although it has also substantial recurrence rate. Here, we report a case of recurred HCC with multiple intrahepatic metastasis at 5 months after surgical resection for small HCC was done. A 55-year-old man with chronic HBV infection received subsegmentectomy for HCC less than 2 cm. A follow-up computed tomography (CT) at 5 months from operation revealed that there were multiple enhancing nodules in entire remnant liver. Intra-arterial injections of adriamycin mixed lipiodol and gelfoam particles were instituted through hepatic artery. We assume that poorly differentiated cellular feature would be attributable to this kind of very early and aggressive recurrence of HCC.

ABSTRACT

BACKGROUND/AIMS: Tenofovir disoproxil fumarate (TDF) plays a pivotal role in the management of drug-resistant chronic hepatitis B. However, it remains unclear whether TDF-nucleoside analogue combination therapy provides better outcomes than TDF monotherapy. This study aimed to compare the efficacy of TDF monotherapy with that of TDF-nucleoside analogue combination therapy in patients with drug-resistant chronic hepatitis B. METHODS: This retrospective cohort study included 76 patients receiving TDF-based rescue therapy for more than 12 months. Suboptimal response was defined as serum HBV-DNA level of >60 IU/mL during prior rescue therapy. Multi-drug resistance was defined as the presence of two or more drug resistance-related mutations confirmed by mutation detection assay. The relationship between baseline characteristics and virologic response (HBV DNA <20 IU/mL) at 12 months were evaluated using logistic regression analysis. RESULTS: Fifty-five patients (72.4%) were suboptimal responders to prior rescue therapy, and 26 (34.2%) had multi-drug resistance. Forty-two patients (55.3%) received combination therapy with nucleoside analogues. Virologic response at 12 months was not significantly different between the TDF monotherapy group and TDF-nucleoside analogue combination therapy group (p=0.098). The serum HBV DNA level was reduced to -4.49+/-1.67 log10 IU/mL in the TDF monotherapy group and to -3.97+/-1.69 log10 IU/mL in the TDF-nucleoside analogue combination therapy group at 12 months (p=0.18). In multivariate analysis, female sex (p=0.032), low baseline HBV-DNA level (p=0.013), and TDF monotherapy (p=0.046) were predictive factors for virologic response at 12 months. CONCLUSIONS: TDF monotherapy showed similar efficacy to that of TDF-nucleoside analogue combination therapy in patients with drug-resistant chronic hepatitis B.

ABSTRACT

BACKGROUND/AIMS: Chronic hepatocellular damage is closely associated with hepatic fibrosis and fatal complication in most liver diseases. The aim of this study is to compare the efficacy and safety of biphenyl dimethyl dicarboxylate (DDB) and ursodeoxycholic acid (UDCA) in patients with abnormal ALT. METHODS: One-hundred thirty-five patients with elevated ALT were randomized to receive either 750 mg/day of DDB or 300 mg/day of UDCA for 24 weeks in 4 referral hospitals. Ninety-three (69%) patients had non-alcoholic steatohepatitits, 27 (20%) had alcoholic hepatitis, and 15 (11%) had chronic hepatitis. The primary end point was the rate of ALT normalization at week 24. The secondary endpoints were changes in AST, liver stiffness, and the incidence of adverse events. RESULTS: A total of 101 patients completed 24 weeks of therapy. ALT normalization at week 24 was observed in 44 (80.0%) patients in DDB group and 16 (34.8%) in UDCA group (p<0.001). Higher mean reduction of ALT levels from baseline to 24 weeks was seen in DDB group compared with UDCA group (-70.0% vs. -35.9%, p<0.001). Normalization of AST level (p=0.53) and change in the liver stiffness (p=0.703) were not significantly different between the two groups. Severe adverse drug reaction occurred in 1 patient in DDB group but the subject continued therapy during the study period. CONCLUSIONS: DDB was not inferior to UDCA for normalizing ALT level. Furthermore it was safe and well tolerated by patients with abnormal ALT.
