<b><i>Aim:</i></b> This study investigated early tumor marker response and treatment response in patients with advanced hepatocellular carcinoma (HCC) treated with lenvatinib. <b><i>Methods:</i></b> Twenty patients with advanced HCC who received lenvatinib were enrolled in this retrospective study. α-Fetoprotein (AFP) and des-γ-carboxyprothrombin (DCP) levels were measured before treatment as well as 2 and 4 weeks after treatment. The objective response rate was evaluated by mRECIST at 6 weeks. <b><i>Results:</i></b> The response rate was 30% (complete response/partial response/stable disease/progressive disease: <i>n</i> = 0/6/6/8 cases) by mRECIST. At 4 weeks, the AFP levels of 12 patients (80%) were lower than at baseline. The AFP levels of 9 patients (60%) continued decreasing from 2 weeks to 4 weeks (sustained-reduction group). In this group, the response rate was 67%. The median AFP change rate was –39% at 4 weeks. In imaging responders, the AFP change rate significantly decreased (<i>p</i> = 0.02). The DCP change rate had no significant correlation with imaging response. The AFP-sustained-reduction group had significantly higher adherence to lenvatinib than the non-sustained-reduction group (<i>p</i> = 0.02). <b><i>Conclusion:</i></b> With lenvatinib therapy for HCC, the AFP levels of most patients had declined at 2 weeks, and at 4 weeks the AFP-sustained-reduction group demonstrated a higher objective response.
Although the effect of levocarnitine (L‐carnitine) on hyperammonemia has been reported in patients with liver cirrhosis (LC), its effect on sarcopenia remains to be elucidated. We assessed the effects of L‐carnitine on sarcopenia in patients with LC. We retrospectively evaluated 52 patients with LC who were treated with L‐carnitine for more than 3 months between February 2013 and June 2017. Computed tomography was used to measure the cross‐sectional area of the skeletal muscles at the level of the third lumbar vertebra. The relative change in skeletal muscle index (SMI) per year (ΔSMI/year) was computed in each patient. We evaluated the relationship between ΔSMI/year and various parameters, such as age, sex, liver functional reserve, and dose of L‐carnitine. The median ΔSMI/year for all patients was −0.22%. The ΔSMI/year values in Child‐Pugh classes A, B, and C were not significantly different among the three groups. There was no significant relationship between ΔSMI/year and sex, age, body mass index, and sarcopenia. Multivariate analysis showed that only a high dose of L‐carnitine (odds ratio [OR], 4.812; 95% confidence interval [CI], 1.233‐18.784; P = 0.024) was associated with increased muscle mass. The L‐carnitine high‐dose group included a significantly larger number of patients with increased muscle mass compared with the low‐dose group (OR, 3.568; 95% CI, 1.138‐11.185; P = 0.027). Administration of L‐carnitine led to a significant and gradual reduction in serum ammonia levels. Conclusion: L‐carnitine seems to suppress the progression of sarcopenia dose dependently, and this was noted to be associated with the improvement of hyperammonemia in patients with LC.
<b><i>Introduction:</i></b> The measurement of body composition such as the skeletal muscle index (SMI) has been reported to be useful for predicting prognosis in hepatocellular carcinoma (HCC). In this study, we analyzed skeletal muscle change during sorafenib and lenvatinib therapy and the association between SMI and prognosis. <b><i>Methods:</i></b> A total of 67 patients with advanced HCC and Child-Pugh grade A status treated with tyrosine kinase inhibitors (TKIs) at Hiroshima University between September 2009 and December 2018 were enrolled in this retrospective cohort study. Patients underwent computed tomography (CT) imaging before starting sorafenib treatment and 1–3 months after treatment initiation. <b><i>Results:</i></b> In all patients, the median SMI was 45.3 cm<sup>2</sup>/m<sup>2</sup> before TKI treatment and 42.1 cm<sup>2</sup>/m<sup>2</sup> after treatment; 54 of 67 (80.6%) patients experienced SMI loss. The median ΔSMI was –1.5 cm<sup>2</sup>/m<sup>2</sup>/months, and no difference in ΔSMI was observed between patients receiving sorafenib and lenvatinib. No significant differences were observed in median ΔSMI between patients with and without progressive disease (–2.35 and –1.1 cm<sup>2</sup>/m<sup>2</sup>/months, respectively), albumin-bilirubin grade 1 and 2 group disease (–1.7 and –1.5 cm<sup>2</sup>/m<sup>2</sup>/months, respectively), and relative dose intensity ≤80 and >80 (–1.8 and –1.2 cm<sup>2</sup>/m<sup>2</sup>/months, respectively). <b><i>Conclusion:</i></b> This report demonstrated that patients receiving TKI treatment experienced a significant loss of skeletal muscle mass regardless of disease progression, hepatic reserve, or which TKI (sorafenib or lenvatinib) they received.
Aim: Combination therapy with sofosbuvir (SOF) plus velpatasvir (VEL) is approved for patients with hepatitis C virus (HCV)-related decompensated cirrhosis. We analyzed the real-world efficacy of SOF/VEL therapy. Methods: Thirty-three patients with HCV-related decompensated cirrhosis (25 and eight patients with Child B and C, respectively) were treated with SOF/VEL for 12 weeks. The HCV non-structural protein (NS)5A and NS5B drug resistance-associated substitutions (RASs) were determined by direct sequencing. Result: Thirty-two of 33 patients completed the treatment, but the remaining patient discontinued the therapy during third week of the treatment due to aggravation of hepatic encephalopathy. Serum HCV-RNA became negative during the treatment in all patients but relapsed after the end of therapy in five patients. In total, 28 out of 33 patients (85%) achieved sustained vi-rological response 12 weeks following completion of treatment (SVR12). The SVR12 rate was 96% in patients with Child B, but significantly lower, at 50%, in patients with Child C (P<0.05). In genotype 1b HCV-infected patients, all eight patients without baseline NS5A RASs, but only three of seven patients with RASs, achieved SVR12. Multivariate analysis identified Child B (odds ratio, 35.8 for Child C; P=0.045) as an independent predictor of SVR12. Median serum albumin levels significantly increased only in patients who achieved SVR12. Child-Pugh scores improved in 16 of 28 patients (57%) following achievement of SVR12. Conclusion: The effect of SOF/VEL therapy is lower for patients with Child C. Improvement of hepatic function is expected after viral eradication with SOF/VEL therapy in patients with decompensated cirrhosis.
Background: Although lenvatinib was recently approved for treatment of advanced unresectable hepatocellular carcinoma (HCC) based on the phase III REFLECT trial, no biomarkers for management of lenvatinib treatment have been established. The aim of this study is to identify predictive biomarkers for the management of lenvatinib treatment in advanced HCC patients. Methods: A total of 41 patients with advanced HCC were enrolled in this retrospective study. Serum levels of 22 circulating cytokines and angiogenic factors (CAFs) were measured by multiplex Luminex assay. Profiles of CAFs, clinical chemistry/hematology parameters, and clinical background were evaluated to explore biomarkers associated with clinical outcomes. Results: Relative dose intensity (RDI) decreased significantly between weeks 1–2 and 3–4 ( p < 0.001), and RDI during weeks 3–4 was a prominent indicator of progression-free survival (PFS). A signature based on baseline serum levels of nine CAFs associated with low RDI was identified. In a multivariate Cox regression analysis, patients with a favorable 9-CAFs signature [hazard ratio (HR) 0.42, 95% confidence interval (CI) 0.18–0.96, p = 0.040] had lower risk, and Child-Pugh grade B (HR 1.6, 95% CI 1.1–8.3, p = 0.026) and presence of macrovascular invasion (MVI; HR 2.9, 95% CI 1.0–8.3, p = 0.045) had higher risk of shorter PFS. Conclusion: This study demonstrates that RDI is an important predictive factor for longer PFS during lenvatinib treatment. In this hypothesis-generating exploratory analysis, we report that a CAF-signature associated with adverse events and RDI could predict PFS, which might contribute to improved management of lenvatinib treatment in HCC patients.
