Presarcopenia is a prognostic factor in patients with hepatocellular carcinoma (HCC). The Japan integrated staging (JIS) score is a prognostic method that combines the Child–Turcotte–Pugh classification and the tumor-node-metastasis (TNM) staging for HCC. We investigated the relationship between presarcopenia, the JIS score, and prognosis in patients with primary HCC. This retrospective study included 153 patients with primary HCC who were hospitalized from October 2011 to March 2018 at Municipal Hospital of Kofu. The skeletal muscle mass was measured using simplified psoas muscle mass index (PMI) based on CT imaging, and PMI using the volume analyzer SYNAPSE VINCENT ver3.0. We diagnosed presarcopenia based on the cut off value according to the assessment criteria for sarcopenia in liver disease defined by the Japan Society of Hepatology. Forty-three patients (28%) were diagnosed with presarcopenia. The median event-free survival was significantly worse in patients with presarcopenia than those without presarcopenia (P = 0.016). In multivariate analysis, presence of presarcopenia, JIS score ≥3, alpha-fetoprotein ≥200 ng/ml, and prothrombin induced by vitamin K absence-II ≥ 200 mAU/ml were significant prognostic factors. Among the patients with JIS scores ≥3, there was no difference in the event occurrence rate with presence of presarcopenia (P = 0.96). Among the patients with JIS scores ≤2, the median event-free-survival was significantly shorter in those with presarcopenia than those without presarcopenia (P = 0.045). Presarcopenia was an independent prognostic factor in patients with primary HCC. In patients with JIS scores ≤2, the median event-free survival was significantly shorter in those with presarcopenia compared to those without presarcopenia. In the patients with JIS scores ≥3, there was no difference in the event occurrence rates in those with and without presarcopenia.

Falls are caused by a combination of factors, including loss of lower limb muscle strength (LMS), and associated with declined performance status (PS). Age-related sarcopenia is generally associated with decreased muscle mass and strength of lower limb muscle but without a noticeable loss of those of upper limb or trunk muscle. However, no reports have focused on falls or LMS in chronic liver disease (CLD) patients. This study is the first to analyze the risk factors for falls in patients with CLD, focusing on LMS measurement using the Locomoscan. This study enrolled 315 CLD patients whose LMS was measured. The patients who experienced falls more than 1 year ago or during the observation period were classified as those who experienced falls. We found that risk factors for falls were PS1/2 and decreased LMS (< 0.32 N/kg). The group with sarcopenia had a higher frequency of decreased LMS (54 vs. 26%, p = 0.001) and falls (24 vs. 4.4%, p < 0.001) compared to the non-sarcopenia group. This study found that decreased LMS was an independent risk factor for falls. Assessment of LMS may be used as a better marker associated with the risk of falls in patients with CLD.

Background: Recent advances in the development of tyrosine kinase inhibitors (TKIs) have enabled patients with unresectable hepatocellular carcinoma (HCC) to receive multiple TKIs in sequence. The aim of this study was to identify predictors of good candidates for second-line treatment after disease progression during sorafenib treatment. Methods: This is a retrospective cohort study of 190 consecutive HCC patients who were treated with sorafenib in our hospital. Three criteria of good candidates for second-line TKI at the time of disease progression during sorafenib treatment were defined as follows: criterion 1 was the same as the inclusion criteria of the regorafenib for patients with hepatocellular carcinoma who progressed on sorafenib treatment (RESORCE) study, criterion 2 was the inclusion criteria of the RESORCE study plus Child–Pugh score 5, and criterion 3 was the inclusion criteria of the RESORCE study plus albumin–bilirubin (ALBI) grade 1. Factors at baseline and at week 4 during sorafenib treatment were used to predict patients fulfilling each of these three criteria. Results: The distribution of patients was 29%, 13%, and 6% in criteria 1, 2, and 3, respectively. Significant factors for meeting criterion 1 was the combination of baseline albumin >3.7 g/dL (odds ratio (OR) 2.7) plus degree of decrease in albumin (Δalbumin) at week 4 <0.2 g/dL (OR 2.6), or the combination of baseline ALBI score <−2.33 (OR 2.5) and ΔALBI at week 4 <0.255 (OR 4.9). For criterion 2, the value of baseline albumin and ALBI score was identical to criterion 1; however, Δalbumin (<0.1 g/dL) and ΔALBI score (3.8 g/dL) and ALBI (<−2.55) became stricter, as did Δalbumin (<0.1 g/dL) and ΔALBI (11) was selected as an additional predictor (OR 5.4). Conclusion: Predictors to satisfy the RESORCE study inclusion criteria were as follows: preserved liver function at baseline, as reflected by albumin or ALBI score, and small deterioration of liver function early during sorafenib therapy, as reflected by Δalbumin or ΔALBI at week 4. Liver function at baseline and degree of change in liver function during sorafenib treatment need to be stricter for better outcomes of liver function with disease progression.

Introduction: Atezolizumab plus bevacizumab combination therapy (AB) was the first-line treatment for unresectable hepatocellular carcinoma (u-HCC). IFN-γ-induced protein 10 (IP-10/CXCL10) is a chemokine to inhibit HCC proliferation by promoting the migration of cytotoxic T cells. We focused on the relationship between plasma IP-10/CXCL10 levels and the initial therapeutic response in patients receiving AB therapy. Methods: Forty-six patients receiving AB therapy were enrolled. Plasma IP-10/CXCL10 levels were measured at baseline, 3–7 days, 3 weeks, 6 weeks, and 8–12 weeks after the start of AB therapy. The initial therapeutic response was evaluated at 8–12 weeks. Results: The baseline IP-10/CXCL10 levels of partial response (PR) group was higher than that of stable disease (SD) or progressive disease (PD) group. Patients with the baseline IP-10/CXCL10 of 84 pg/mL or higher were likely to present PR than patients below (71 vs. 35%, p = 0.031), but prediction of PD using the baseline IP-10/CXCL10 levels was difficult. In contrast, IP-10/CXCL10 ratio of the PR group was lower than that of the SD/PD group at 3, 6, and 8–12 weeks. Patients with the 3, 6, and 8–12 weeks IP-10/CXCL10 ratio of 1.3, 0.4, and 0.4 or lower were likely to present PR than patients with ≥1.3, 0.4, and 0.4 (88, 35, 35 vs. 30, 3.8, 0%, p < 0.001, 0.011, 0.002). In other hand, the 3, 6, and 8–12 weeks IP-10/CXCL10 ratio for PD group was higher than that for non-PD group. Patients with the 3, 6, and 8–12 weeks IP-10/CXCL10 ratio of 1.3, 1.7, and 1.9 or higher were likely to present PD than patients below (85, 62, 57 vs. 32, 23, 14%, p = 0.002, 0.034, 0.009). Conclusion: High baseline IP-10/CXCL10 levels may be associated with better outcome, and high IP-10/CXCL10 ratio after 3–12 weeks may be associated with worse outcome in u-HCC patients receiving AB therapy.

Background: A test to narrow down patients who require esophagogastroduodenoscopy (EGD) with a high probability of having gastroesophageal varices (GEV) and a high-risk of liver-related events is an unmet need. Methods: The measurement of serum fibrosis markers and EGD was performed in 166 consecutive chronic hepatitis C patients. The correlation between the grades of GEV and fibrosis markers and the subsequent occurrence of liver-related and fibrosis markers were examined. Results: Wisteria floribunda agglutinin-positive human Mac-2 binding protein (WFA+–M2BP) levels increased according to the grade of GEV (3.4 (0.2–18.6) for no GEV, 7.9 (1.8–20.0) for small GEV, and 11.4 (4.0–20.0) for large GEV; p < 0.001). The diagnostic accuracy of the WFA+–M2BP was superior compared to other serum fibrosis markers, and WFA+–M2BP was an independent predictor of GEV in the multivariate analysis. Furthermore, the cumulative incidence of liver-related events at one year was 2.3% in patients with WFA+–M2BP levels ≤ 7.0 and 37.5% in patients with WFA+–M2BP levels > 7.0 (p < 0.001). WFA+–M2BP > 7.0 was a significant predictive factor for liver-related events (Hazard ratio 6.7, p = 0.004) independent of Child–Pughclass. Conclusions: WFA+–M2BP could be used to estimate the presence and grade of GEV and is linked to liver-related events in chronic hepatitis C patients.

Aim: Atezolizumab plus bevacizumab (AB) combination therapy is the first‐line treatment for unresectable hepatocellular carcinoma (u‐HCC). The management of immune‐related adverse events (irAEs) is an important issue associated with achieving a good therapeutic response in patients receiving AB therapy. However, few studies have reported irAE development in patients receiving AB therapy. This study focused on the association between irAE development and autoantibodies at baseline in patients receiving AB therapy.Methods: Sixty‐one patients receiving AB therapy were enrolled. For autoantibodies, the following antibodies were tested before the start of AB therapy: antinuclear antibodies, rheumatoid factor (RF), anti‐thyroglobulin antibodies, thyroid peroxidase antibodies, anti‐thyroid stimulating hormone receptor antibodies, and acetylcholine receptor antibodies. A patient was considered to have pre‐existing antibodies if any of the listed antibodies were present at baseline.Results: Ten patients (16%) developed irAEs during the observation period. The irAEs included liver injury, hypothyroidism, adrenal insufficiency, adrenocorticotropic hormone deficiency, and rhabdomyolysis. Patients with irAE (n = 10) were more likely to be positive for any autoantibody (hazard ratio [HR] 3.7, p = 0.047) and RF at baseline (HR 5.4, p = 0.035) and to achieve complete response (HR 5.8, p = 0.027) than those without. The presence of autoantibodies at baseline was an independent factor associated with irAE development.Conclusion: In the real world, 16% of patients receiving AB therapy for u‐HCC developed irAEs. Patients with autoantibodies at baseline are at high risk of developing irAEs and require cautious follow‐up.
