RESUMO

BACKGROUND: Lenvatinib and sorafenib are key therapeutic agents for hepatocellular carcinoma. However, there are no useful biomarkers for selecting molecular-targeted agents (MTAs). Skeletal muscle volume is associated with the clinical outcomes in these patients. We investigated the effects of lenvatinib and sorafenib on the skeletal muscles of patients with HCC. METHODS: We evaluated the impact of skeletal muscle changes over a 3-month period for each MTA (n = 117; lenvatinib/sorafenib, 45/72). The skeletal muscle mass index (SMI) was measured at the third lumbar vertebra. Furthermore, we evaluated the direct effect of each MTA on primary human skeletal muscle cells by estimating muscle protein synthesis using western blot analysis. RESULTS: The median change in SMI was -0.7% (p = 0.959) and -5.9% (p <0.001) for the lenvatinib and sorafenib groups, respectively. Sorafenib had a greater effect on skeletal muscle loss than lenvatinib (p < 0.001). Additionally, SMI significantly decreased in the sorafenib group regardless of initial skeletal muscle volume (p < 0.001), whereas no significant differences were observed in the lenvatinib group. Sorafenib therapy (odds ratio [OR], 2.98; p = 0.023) and non-muscle depletion (OR, 3.31; p = 0.009) were associated with a decreased SMI. In vitro analysis showed that sorafenib negatively affected muscle synthesis compared to lenvatinib. CONCLUSIONS: Sorafenib may have a more negative effect on skeletal muscle than lenvatinib.

RESUMO

Despite the promising efficacy of atezolizumab plus bevacizumab (atezo/bev), some patients with unresectable hepatocellular carcinoma (HCC) experience disease progression. This retrospective study, which included 154 patients, aimed to evaluate predictors of treatment efficacy of atezo/bev for unresectable HCC. Factors associated with treatment response were examined, focusing on tumor markers. In the high-alpha-fetoprotein (AFP) group (baseline AFP ≥ 20 ng/mL), a decrease in AFP level > 30% was an independent predictor of objective response (odds ratio, 5.517; p = 0.0032). In the low-AFP group (baseline AFP < 20 ng/mL), baseline des-gamma-carboxy prothrombin (DCP) level < 40 mAU/mL was an independent predictor of objective response (odds ratio, 3.978; p = 0.0206). The independent predictors of early progressive disease were an increase in AFP level ≥ 30% at 3 weeks (odds ratio, 4.077; p = 0.0264) and the presence of extrahepatic spread (odds ratio, 3.682; p = 0.0337) in the high-AFP group and up-to-seven criteria, OUT (odds ratio, 15.756; p = 0.0257) in the low-AFP group. In atezo/bev therapy, focusing on early AFP changes, baseline DCP, and tumor burden of up-to-seven criteria are useful in predicting response to treatment.

RESUMO

AIM: Primary hepatic angiosarcoma (PHA) is extremely rare, and its imaging findings are similar to those of other liver tumors including hepatocellular carcinoma (HCC). Here, we report a case of hepatitis C virus (HCV)-related HCC followed by PHA that showed remarkable clinical response to atezolizumab plus bevacizumab (Atezo/Bev) therapy. CASE PRESENTATION: A 78-year-old man with recurrent HCC had a liver tumor with lymphadenopathy. Although considered as HCC recurrence, microscopic examination of the resected liver and lymph node showed PHA. Three months later, a solitary lung nodule was newly detected and subsequently resected. The pathological diagnosis was poorly differentiated HCC. Therefore, the patient was finally diagnosed with double cancer of PHA and HCC. Thereafter, he developed a new liver tumor with lymphadenopathy and received Atezo/Bev therapy. Liver tumor biopsy was carried out before the treatment. The pathological diagnosis was angiosarcoma. The patient showed a partial response after two courses of Atezo/Bev therapy. CONCLUSION: To our best knowledge, this report is the first case to present HCV-related HCC followed by PHA and to show that Atezo/Bev therapy is beneficial for PHA.

RESUMO

BACKGROUND: We previously reported liver stiffness (LS) as a prognostic predictor of portosystemic shunt (PSS) occlusion. This study aims to reinvestigate the predictive factors of the model for end-stage liver disease-sodium (MELD-Na) score amelioration following balloon-occluded retrograde transvenous obliteration (BRTO) and to evaluate the postoperative prognoses of patients with portal hypertension by using newly identified factors. METHODS: Seventy-five patients who underwent BRTO between 2008 and 2021 were retrospectively enrolled. The MELD-Na scores were calculated preoperatively and one month postoperatively. We monitored long-term outcomes and analyzed postoperative survival. RESULTS: At one month postoperatively, the MELD-Na score decreased in 46 (61.3%) patients. Univariate analyses revealed a significant association of the score amelioration with nine factors, including lower LS levels and a higher international normalized ratio (INR). A multivariate logistic regression analysis with receiver operating characteristic curve analyses identified preoperative LS levels and INR as significant independent predictors of the postoperative MELD-Na score amelioration, with optimal cutoffs of 28.1 kPa and 1.06, respectively. The combination of LS < 28.1 kPa and INR ≥ 1.06 showed a sensitivity and specificity of 84.8% and 75.9% for the prediction of the score amelioration, respectively. For the propensity score model, we matched 24 patients with similar age, sex, MELD-Na score, and concomitant hepatocellular carcinoma. Kaplan-Meier analysis determined significantly higher cumulative survival rates in patients with LS < 28.1 kPa and INR ≥ 1.06 than in other populations. CONCLUSIONS: A combination of LS and INR can predict the MELD-Na score amelioration and prognosis improvement following PSS occlusion.
