Aim: This study aimed to compare the prognostic performance of the risk models for patients with hepatocellular carcinoma (HCC) receiving atezolizumab and bevacizumab (Atez/Bev) as first-line treatment.

Methods: Among 449 patients included in this retrospective multicenter study, we compared the prognostic performance of 13 risk models for the 12-month and 18-month survival status using area under the curve (AUC), net reclassification improvement (NRI), and relative integrated discrimination improvement (IDI) analysis. We also constructed a calibration plot to assess the fitness of each model.

In the current era of immune therapy, lenvatinib (LEN) continues to be vital for treating unresectable hepatocellular carcinoma (uHCC) patients. This study investigates the importance of nutritional status in the prognosis of uHCC patients receiving LEN and evaluates a new prognostic scoring system that combines the geriatric nutritional risk index (GNRI) and systemic inflammatory response. From 2018 to 2022, 484 uHCC patients treated with LEN (384 males, median age 73).

Background: The clinical course of esophagogastric varices (EGV) after sustained virological response (SVR) with direct-acting antiviral (DAA) therapy has not been clearly elucidated. The predictors for the worsening/improvement of EGV after SVR with DAA therapy were investigated.

Methods: Of the cirrhosis patients who achieved SVR with DAA therapy, 328 patients who underwent endoscopic examinations both before and after DAA therapy were enrolled.

Aim: Since the development of tremelimumab plus durvalumab (Dur/Tre) for unresectable hepatocellular carcinoma (uHCC), it has been used as not only an initial but also later line treatment in clinical practice. This study aimed to elucidate clinical prognostic factors for progression-free survival (PFS) in Dur/Tre treatment cases.

Methods: Enrolled were 183 uHCC patients treated with Dur/Tre from 2023 to May 2024 (median age, 74 years; male patients, 152; Child-Pugh class A:B, 150:33; Barcelona Clinic Liver Cancer stage B:C, 59:124; initial line use, 64).

Introduction: The most frequently used first-line treatment in patients with advanced hepatocellular carcinoma (HCC) is atezolizumab plus bevacizumab. Upon progression after this treatment, the standard of care in many countries is sorafenib, due to the lack of reimbursement for other drugs. Several randomized trials are currently underway to clarify the best second-line therapy in patients with HCC.

Article Synopsis
  • * A retrospective analysis of 885 HCC patients showed no significant differences in overall survival, time to progression, or disease control rates between viral and nonviral patients treated with the combination therapy.
  • * Common prognostic factors were identified across both groups, but there might be some stronger associations between immunological factors and outcomes specifically in viral patients, while treatment-related toxicities and second-line treatments showed nearly identical results for both etiology subgroups.

  • The study investigates the challenges of selective biliary cannulation during endoscopic retrograde cholangiopancreatography (ERCP), focusing on how different papillary morphologies can complicate the process.
  • Researchers analyzed data from 776 patients to identify risk factors for cannulation difficulties, finding that certain types of papillae, the presence of periampullary diverticulum (PAD), and scope operability significantly impacted success rates.
  • The study concluded that specific patterns can predict cannulation difficulties, helping to inform whether to use conventional or salvage techniques in treatment.

Aim: It is not uncommon to encounter outpatients in the hepatology department with harmful alcohol habits. When treating such chronic liver disease (CLD) patients, an adequate intervention method for harm reduction of alcohol use, such as brief intervention (BI) or BI and nalmefene, should be considered. This study aimed to elucidate the clinical effectiveness of BI for CLD patients affected by harmful alcohol use.

Article Synopsis
  • Lenvatinib is a treatment for advanced hepatocellular carcinoma (aHCC), but it can increase the risk of bleeding from esophagogastric varices (EGVs). This study looked into how common EGVs are, what predicts their bleeding, and the complications they cause in patients receiving lenvatinib.
  • A total of 535 cirrhotic patients undergoing lenvatinib treatment were examined. The study found that 44% of these patients had EGVs, with a 3% incidence of bleeding over 12 months, mainly occurring in patients identified as being at high risk for EGVs.
  • The only notable predictor for EGV bleeding was having high-risk

Background/aim: Unresectable recurrence after curative treatments for hepatocellular carcinoma (HCC) is a life-limited event. Although the IMbrave050 trial (IM050) showed a favorable reduction in recurrence with adjuvant immune-combination chemotherapy, inclusion criteria of the radiofrequency ablation (RFA) group were lower risk than that of the resection group. This study aimed to elucidate the clinical features of patients treated with RFA, which really need adjuvant-chemotherapy.

Article Synopsis
  • - The study examines the impact of Body Mass Index (BMI) on survival among patients with advanced liver cancer (HCC) undergoing first-line treatment with either atezolizumab plus bevacizumab or lenvatinib, focusing on underweight, normal-weight, and overweight classifications.
  • - In a cohort of 1,292 patients, results indicated that underweight individuals had significantly shorter overall survival (OS) compared to normal-weight patients, while no significant differences in OS were observed between normal and overweight patients.
  • - The research highlights the differing prognostic implications of BMI in cancer treatment, suggesting that underweight patients may require more focused clinical considerations in advanced HCC therapy.

Background And Aim: The study aims to develop a novel predictive model including the fibrosis (FIB)-3 index for hepatocellular carcinoma (HCC) development in patients with chronic hepatitis C virus (HCV) who achieved sustained virological response (SVR) with direct-acting antiviral (DAA) therapy.

Methods: This study included 2529 patients in whom HCV was eradicated with DAA therapy. The after DAA recommendation for surveillance (ADRES) score, which is based on sex, FIB-4 index, and α-fetoprotein, was used to predict HCC development.

Introduction: Because of recent developments in treatments for hepatocellular carcinoma (HCC), methods for determining suitable therapy for initial or recurrent HCC have become important. This study used artificial intelligence (AI) findings to establish a system for predicting prognosis of HCC patients at time of reoccurrence based on clinical data as a reference for selection of treatment modalities.

Methods: As a training cohort, 5,701 observations obtained at the initial and each subsequent treatment for recurrence from 1,985 HCC patients at a single center from 2000 to 2021 were used.

Atezolizumab plus bevacizumab (AB) and lenvatinib can be alternatively used as first-line systemic treatment of unresectable hepatocellular carcinoma (HCC). However, no direct comparison of the two regimens has been performed in randomized clinical trials, making the identification of baseline differential predictors of response of major relevance to tailor the best therapeutic option to each patient. Baseline clinical and laboratory characteristics of real-world AB-treated HCC patients were analyzed in uni- and multivariate analyses to find potential prognostic factors of overall survival (OS).

Article Synopsis
  • The study aimed to compare the effects of two treatments, atezolizumab plus bevacizumab (Atez/Bev) and lenvatinib (LEN), on liver function in patients with hepatocellular carcinoma.
  • A total of 526 patients who received Atez/Bev and 731 who received LEN were analyzed, with 324 patients in each group after matching, using a model to evaluate liver health changes over time.
  • Both treatments led to similar deterioration in liver function scores, with significant worsening observed in LEN-treated patients who were at an advanced cancer stage or received a full dose, highlighting the need for caution in these cases.
