The Analysis of Muscle Volume Measured by Bioelectrical Impedance in Patients with Hepatocellular Carcinoma Treated with First-Line Atezolizumab plus Bevacizumab Combination Therapy or First-Line Lenvatinib.

INTRODUCTION: Measurements of body composition, such as the skeletal muscle index (SMI), are useful for predicting prognosis in hepatocellular carcinoma (HCC). This study aimed to analyze the relationship between skeletal muscle changes during therapy with atezolizumab plus bevacizumab (Atezo + Beva) or lenvatinib (Len) and the association between SMI and prognosis. METHODS: Patients with advanced HCC and Child-Pugh A status received Atezo + Beva or Len as first-line systemic chemotherapy. We assessed prognosis and body composition obtained by bioelectrical impedance analysis. RESULTS: A total of 109 patients received treatment (Atezo + Beva, n = 47; Len, n = 62). During treatment, the arm SMI was reduced in the Len group and maintained in the Atezo + Beva group. The extracellular water to total body water ratio (ECW/TBW) increased significantly in both groups during treatment. In the Atezo + Beva group, no factor was associated with prognosis. Multivariate analysis showed that in the Len group, the arm SMI (hazard ratio [HR], 0.5; 95% CI: 0.26-0.89; p = 0.02), ECW/TBW (HR: 2.7; 95% CI: 1.21-6.01; p = 0.01), and Child-Pugh score (HR: 2.3; 95% CI: 1.31-6.13; p = 0.004) were associated with progression-free survival. CONCLUSION: Assessing body composition with BIA before Atezo + Beva and Len treatment may be useful.

Clinical Outcomes of 2nd- and 3rd-Line Regorafenib for Advanced Hepatocellular Carcinoma.

INTRODUCTION: This study compared clinical outcomes of 2nd- and 3rd-line regorafenib in patients with unresectable hepatocellular carcinoma. METHODS: In this retrospective cohort study, 48 patients were treated with regorafenib for unresectable hepatocellular carcinoma. Thirty-five and 13 patients were initiated on 2nd- and 3rd-line therapy, respectively. We assessed the responses to and safety of the therapy. RESULTS: There were no statistically significant differences in clinical characteristics at the start of 2nd- or 3rd-line regorafenib therapy. The overall response rate of 2nd- and 3rd-line regorafenib was 20 and 8%, respectively. The disease control rate was 57 and 54%, respectively. Median overall survival (mOS) from the start of 2nd-line regorafenib was 17.5 months. mOS from the start of 3rd-line regorafenib was not obtained. Median progression-free survival of 2nd- and 3rd-line regorafenib was 4.9 and 2.3 months, respectively. mOS from 1st-line therapy with tyrosine kinase inhibitor plus sorafenib-regorafenib-lenvatinib was 29.5 months; that with lenvatinib-sorafenib-regorafenib was not obtained. Patients on 3rd-line therapy tended to have better Child-Pugh scores and tumor factors at the start of 1st-line therapy than other patients. CONCLUSION: Patients on 2nd- and 3rd-line regorafenib showed favorable responses. Good Child-Pugh scores and tumor factors may be associated with a better response rate and OS.
