Background/aim Sarcopenia is recognized as a condition related to quality of life and prognosis in patients with chronic liver disease, although no useful strategy for improving muscle volume and strength has been established. Here, we evaluated the efficacy of supplementation with branched-chain amino acid (BCAA) administration and walking exercise. Patients and methods From December 2015 to July 2016, 33 Japanese outpatients with liver cirrhosis were enrolled (median: 67 years, HCV : HBV : alcohol : others=26 : 2 : 2 : 3, male : female=13 : 20, Child-Pugh A : B=30 : 3). None had a history of BCAA supplementation. After calculating the average number of daily steps using a pedometer for a 2–3-week period, BCAA supplementation (protein 13.5 g, 210 kcal/day) as a late evening snack and walking exercise (additional 2000 steps/day prescribed) were started. Body composition including muscle volume was analyzed using a bioelectrical impedance analysis method, and serological data and muscle strength (leg, handgrip) were evaluated at enrollment, and then 1, 2, and 3 months after starting the protocol. Results The median average number of daily steps was 3791 (interquartile range: 2238–5484). The average period of BCAA supplementation was 2.7±0.7 months. During the period from enrollment to 3 months after starting the protocol, HbA1c and NH3 were not significantly changed, whereas the BCAA/tyrosine ratio improved (4.3±1.35 to 5.24±2.04, P=0.001). In addition, the ratios for average daily steps (1.595, P=0.02) as well as muscle volume, leg strength, and handgrip strength (1.013, 1.110, and 1.056, respectively; all P<0.01) were increased at 3 months. Conclusion BCAA supplementation and walking exercise were found to be effective and easily implemented for improving muscle volume and strength in liver cirrhosis patients.

To develop a scoring method using with common clinical data for predicting hepatocellular carcinoma (HCC) development after sustained virological response at 24 weeks (SVR24) after treatment with direct acting antivirals (DAAs), we retrospectively evaluated clinical features of patients who obtained SVR24.

Background/Aim: Determination of failure of transarterial chemoembolization (TACE) for treatment of Barcelona Clinic Liver Cancer stage B (BCLC-B) hepatocellular carcinoma (HCC) has become important because of the development of tyrosine kinase inhibitor (TKI) treatment. We evaluated the usefulness and efficacy of the newly proposed time to TACE progression (TTTP). Patients and Methods: From 2006 to 2016, 192 BCLC-B HCC patients [median age 72 years, male/female ratio = 149/43, Child-Pugh score 5/6/7 = 106/56/30, albumin-bilirubin (ALBI) grade 1/2 = 64/128, Kinki criteria B1/B2 = 64/128] were enrolled. TTTP was defined based on a previous report and first imaging performed 3 months after initial TACE had been used to obtain baseline images. The patients were divided into three groups according to TTTP (<5, 5-10, and ≥10 months; group I, II, and III, respectively). We evaluated the relationship between TTTP and overall survival (OS) as well as the prognostic factors for death. Results: The median number of TACE procedures was 4 (interquartile range 3-7). There was a moderate correlation between TTTP and OS (r = 0.527, 95% CI 0.416-0.622, p < 0.001). The median survival for group I (n = 78), II (n = 49), and III (n = 65) was 24.6, 34.7, and 49.5 months, respectively (group I vs. group II, p = 0.023; group I vs. group III, p < 0.001; group II vs. group III, p = 0.037; Holms method). ALBI grade 2 (HR 1.548, 95% CI 1.004-2.388, p = 0.048), alpha-fetoprotein (>100 ng/mL) (HR 1.540, 95% CI 1.035-2.291, p = 0.033), and TTTP (<5 months) (HR 2.157, 95% CI 1.447-3.215, p < 0.001) were significant prognostic factors for death in multivariate Cox hazard analysis. Conclusion: In patients with reduced TTTP, especially <5 months, it might be difficult to improve prognosis with a repeated TACE procedures. In such cases, reconsideration of the therapeutic strategy might be needed when possible.

Aim/Background: Evaluations of abdominal ultrasonography (US) findings of primary and secondary tumor-forming hepatic malignant lymphoma (HML) have not been adequately reported. In this study, we elucidated US and contrast-enhanced US (CEUS) findings in patients with HML. Materials/Methods: From January 2006 to March 2017, 25 patients with HML were enrolled (primary 7, secondary 18), each of whom was diagnosed pathologically. They were divided into 2 groups based on tumor diameter (cutoff, 30 mm). US imaging findings were retrospectively analyzed. Results: All tumors in patients with a small HML (<30 mm in diameter, small group, n = 14) were revealed as homogeneous hypo-echoic type (100%), with penetrating sign observed in only 1 patient. Tumors in 11 patients in the small group, examined with CEUS, showed homogeneous enhancement in the early vascular phase (91%) and a washout pattern in the portal phase (100%), and they were revealed as defective in the post-vascular phase (100%). In the large group (≥30 mm; n = 11), tumors were revealed as a heterogeneous hypo-echoic lesion in 10 (91%) and penetrating sign was observed in 8 (73%). Dilatation of the distal intrahepatic bile duct by the tumor was observed in 4 patients in the large group. In 7 large group patients examined with CEUS, imaging findings in the early vascular phase varied, with 5 (71%) showing a washout pattern in the portal phase and 5 (71%) revealed as defective in the post-vascular phase. Conclusion: We found that US imaging features of HML differ depending on the tumor diameter.
