Supplementary Material for: Serum angiopoietin-2 levels predict the development of hepatocellular carcinoma following hepatitis C virus eradication using direct-acting antiviral agents

Introduction: Our previous studies showed that serum angiopoietin-2 (Ang-2) and C-X-C motif chemokine ligand 10 (CXCL10) levels predicted improvement in liver fibrosis following sustained virological response (SVR) of hepatitis C virus (HCV) obtained with administration of with direct-acting antiviral agents (DAAs). These levels were evaluated retrospectively as predictive indicators of hepatocellular carcinoma (HCC) development following SVR. Methods: We enrolled individuals from a historical cohort of 89 chronic HCV patients without history of HCC at baseline and with SVR following DAA therapy and had baseline serum levels of Mac-2 binding protein glycosylation isomer ≥ 2.0 C.O.I. Results: Multivariate analyses revealed that only the Ang-2 level at 24 weeks following the end of treatment (EOT24W) was significantly related to HCC development (hazard ratio 2.27; P = 0.003). This result was reproduced in individuals without history of HCC and with advanced liver fibrosis (M2BPGi level ≥ 3.3 C.O.I. at baseline). Time-dependent receiver operating characteristic curve analyses for the future risk of developing HCC within 5 years of follow-up (5y-HCC) showed the best cut-off Ang-2 level at the EOT24W was 2,780 pg/mL, and significantly stratified the cumulative incidence of HCC (≥ 2,780 vs. < 2,780 pg/mL, 5y-HCC: 45.5 vs. 8.2%, P < 0.001). Conclusions: At the EOT24W, serum Ang-2 level predicts the likelihood of developing HCC following SVR to DAA therapy

Supplementary Material for: Prognostic nutritional index after introduction of atezolizumab with bevacizumab predicts prognosis in advanced hepatocellular carcinoma: A multicenter study

Introduction: Atezolizumab plus bevacizumab (Atez/Bev) is the preferred treatment for advanced hepatocellular carcinoma (HCC). However, biomarkers of therapeutic efficacy have remained unclear. We took a retrospective approach to explore the role of prognostic nutritional index (PNI) for predicting the outcomes of Atez/Bev treatment. Methods: One hundred twenty-five HCC patients were enlisted; these patients received Atez/Bev treatment and underwent dynamic computerized tomography/magnetic resonance imaging to determine the treatment response on at least one occasion between October 2020 and January 2023, and their PNI before treatment and at the beginning of the second cycle (PNI-2c) was evaluated. Results: During the initial evaluation, 2 (2%), 28 (22%), 70 (56%), and 25 (20%) patients exhibited a complete response (CR), partial response (PR), stable disease (SD), and progressive disease (PD), respectively. Patients with non-PD tended to have higher PNI at baseline and PNI-2c than those with PD (p = 0.245 and 0.122, respectively), with optimal baseline PNI and PNI-2c cut-off values of 42.6 and 40.4, respectively. PNI at baseline could not be used to predict overall survival (OS) or progression-free survival (PFS). However, PNI-2c predicted OS and PFS (PNI-2c ≥ 40.4 vs. < 40.4: 25.3 vs. 16.2 months, P = 0.008 for OS; 12.7 vs. 8.4 months, P = 0.036 for PFS). A multivariate analysis showed a significant association between PNI-2c and OS. Conclusions: PNI-2c is a predictor of prognosis in HCC patients treated with Atez/Bev therapy
