Real Life Study of Lenvatinib Therapy for Hepatocellular Carcinoma: RELEVANT Study

Introduction: In the REFLECT trial, lenvatinib was found to be noninferior compared to sorafenib in terms of overall survival. Here, we analyze the effects of lenvatinib in the real-life experience of several centers across the world and identify clinical factors that could be significantly associated with survival outcomes. Methods: The study population was derived from retrospectively collected data of HCC patients treated with lenvatinib. The overall cohort included western and eastern populations from 23 center in five countries. Results: We included 1,325 patients with HCC and treated with lenvatinib in our analysis. Median OS was 16.1 months. Overall response rate was 38.5%. Multivariate analysis for OS highlighted that HBsAg positive, NLR >3, and AST >38 were independently associated with poor prognosis in all models. Conversely, NAFLD/NASH-related etiology was independently associated with good prognosis. Median progression-free survival was 6.3 months. Multivariate analysis for progression-free survival revealed that NAFLD/NASH, BCLC, NLR, and AST were independent prognostic factors for progression-free survival. A proportion of 75.2% of patients suffered from at least one adverse effect during the study period. Multivariate analysis exhibited the appearance of decreased appetite grade ≥2 versus grade 0-1 as an independent prognostic factor for worse progression-free survival. 924 patients of 1,325 progressed during lenvatinib (69.7%), and 827 of them had a follow-up over 2 months from the beginning of second-line treatment. From first-line therapy, the longest median OS was obtained with the sequence lenvatinib and immunotherapy (47.0 months), followed by TACE (24.7 months), ramucirumab (21.2 months), sorafenib (15.7 months), regorafenib (12.7 months), and best supportive care (10.8 months). Conclusions: Our study confirms in a large and global population of patients with advanced HCC, not candidates for locoregional treatment the OS reported in the registration study and a high response rate with lenvatinib

Sequential therapies after atezolizumab plus bevacizumab or lenvatinib first-line treatments in hepatocellular carcinoma patients

Introduction: The aim of this retrospective proof-of-concept study was to compare different second-line treatments for patients with hepatocellular carcinoma and progressive disease (PD) after first-line lenvatinib or atezolizumab plus bevacizumab.Materials and methods: A total of 1381 patients had PD at first-line therapy. 917 patients received lenvatinib as first-line treatment, and 464 patients atezolizumab plus bevacizumab as first-line.Results: 49.6% of PD patients received a second-line therapy without any statistical difference in overall survival (OS) between lenvatinib (20.6 months) and atezolizumab plus bev-acizumab first-line (15.7 months; p = 0.12; hazard ratio [HR] = 0.80). After lenvatinib first-line, there wasn't any statistical difference between second-line therapy subgroups (p = 0.27; sorafenib HR: 1; immunotherapy HR: 0.69; other therapies HR: 0.85). Patients who under-went trans-arterial chemo-embolization (TACE) had a significative longer OS than patients who received sorafenib (24.7 versus 15.8 months, p < 0.01; HR = 0.64). After atezolizumab plus bevacizumab first-line, there was a statistical difference between second-line therapy subgroups (p < 0.01; sorafenib HR: 1; lenvatinib HR: 0.50; cabozantinib HR: 1.29; other therapies HR: 0.54). Patients who received lenvatinib (17.0 months) and those who under-went TACE (15.9 months) had a significative longer OS than patients treated with sorafenib (14.2 months; respectively, p = 0.01; HR = 0.45, and p < 0.05; HR = 0.46).Conclusion: Approximately half of patients receiving first-line lenvatinib or atezolizumab plus bevacizumab access second-line treatment. Our data suggest that in patients progressed to atezolizumab plus bevacizumab, the systemic therapy able to achieve the longest survival is lenvatinib, while in patients progressed to lenvatinib, the systemic therapy able to achieve the longest survival is immunotherapy

Regional differences in clinical presentation and prognosis of patients with post-sustained virologic response (SVR) hepatocellular carcinoma.

Background& Amis: Widespread use of direct-acting antivirals (DAAs) for hepatitis C virus (HCV) infection has resulted in increased numbers of patients with hepatocellular carcinoma (HCC) after achieving sustained virologic response ('post-SVR HCC') worldwide. Few data compare regional differences in presentation and prognosis of patients with post-SVR HCC.MethodsWe identified patients with advanced fibrosis (F3/F4) who developed incident post-SVR HCC between March, 2015 and October, 2021 from 30 sites in Europe, North America, South America, Middle East, South Asia, East Asia, and Southeast Asia. We compared patient demographics, liver dysfunction, and tumor burden by region. We compared overall survival by region using Kaplan-Meier analysis and identified factors associated with survival using multivariable Cox regression analysis.ResultsAmong 8,796 patients with advanced fibrosis or cirrhosis who achieved SVR, 583 (6.6%) developed incident HCC. There was marked regional variation in the proportion of detection by surveillance (range: 59.5-100%), median maximum tumor diameter (range: 1.8-5.0 cm), and proportion with multinodular HCC (range: 15.4-60.8%). Prognosis of patients highly varied by region (HR range: 1.82-9.92), with the highest survival in East Asia, North America, and South America, and lowest in the Middle East and South Asia. After adjusting for geographic region, HCC surveillance was associated with early-stage detection (BCLC stage 0/A: 71.0% vs. 21.3%, pConclusionsClinical characteristics, including early-stage detection, and prognosis of post-SVR HCC significantly differed across geographic regions. Surveillance utilization appears to be a high-yield intervention target to improve prognosis among patients with post-SVR HCC globally

Utility of FIB4-T as a Prognostic Factor for Hepatocellular Carcinoma

Background: Most integrated scores for predicting the prognosis of patients with hepatocellular carcinoma (HCC) comprise tumor progression factors and liver function variables. The FIB4 index is an indicator of hepatic fibrosis calculated on the basis of age, aspartate aminotransferase (AST) levels, alanine aminotransferase (ALT) levels, and platelet count, but it does not include variables directly related to liver function. We propose a new staging system, referred to as “FIB4-T,” comprising the FIB4 index as well as tumor progression factors, and examine its usefulness. Method: Subjects included 3800 cases of HCC registered in multiple research centers. We defined grades 1, 2, and 3 as a Fibrosis-4 (FIB4) index of <3.25, 3.26–6.70, and >6.70 as FIB4, respectively, and calculated the FIB4-T in the same manner in which the JIS (Japan Integrated Staging Score) scores and albumin-bilirubin tumor node metastasis (ALBI-T) were calculated. We compared the prognostic prediction ability of FIB4-T with that of the JIS score and ALBI-T. Results: Mean observation period was 37 months. The 5-year survival rates (%) of JIS score (0/1/2/3/4/5), ALBI-T (0/1/2/3/4/5) and FIB4-T (0/1/2/3/4/5) were 74/60/36/16/0, 82/66/45/22/5/0 and 88/75/65/58/32/10, respectively. Comparisons of the Akaike information criteria among JIS scores, ALBI-T, and FIB4-T indicated that stratification using the FIB4-T system was comparable to those using ALBI-T and JIS score. The risk of mortality significantly increased (1.3–2.8 times/step) with an increase in FIB4-T, and clear stratification was possible regardless of the treatment. Conclusions: FIB4-T is useful in predicting the prognosis of patients with HCC from a new perspective

Attempt to establish prognostic predictive system for hepatocellular carcinoma using artificial intelligence for assistance with selection of treatment modality

Background/Aim: 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. Material/Methods: As a training cohort, 5701 observations obtained at the initial and each subsequent treatment for recurrence from 1985 HCC patients at a single center from 2000 to 2021 were used. The validation cohort was 5692 observations from patients at multiple centers obtained at the time of the initial treatment. An AI calculating system (PRAID) was constructed based on 25 clinical factors noted at each treatment from the training cohort, then predictive prognostic values for one- and three-year survival in both cohorts were evaluated. Results: After exclusion of patients lacking clinical data regarding albumin-bilirubin grade (ALBI) and/or tumor-node-metastasis stage (TNM), ALBI-TNM (ALBI-T) and modified ALBI-T scores confirmed that prognosis for patients in both cohorts was similar. The area under the curve (AUC) for prediction of both one- and three-year survival in the validation cohort were 0.841 [sensitivity 0.933 (95%CI 0.925-0.940), specificity 0.517 (95%CI 0.484-0.549)] and 0.796 [sensitivity 0.806 (95%CI 0.790-0.821), specificity 0.646 (95%CI 0.624-0.668)], respectively. Conclusion: The present PRAID system might provide useful prognostic information related to short and medium survival for decision making regarding best therapeutic modality for both initial and recurrent HCC cases

The prognosis of elderly patients with hepatocellular carcinoma: A multi‐center 19‐year experience in Japan

Abstract Aims This retrospective study compared the survival between elderly and non‐elderly patients. Methods A total of 5545 treatment‐naive patients with hepatocellular carcinoma (HCC) who visited 7 different hospitals from January 2000 to December 2018 were included. Patients ≥80 years old were defined as elderly patients. We divided the patients into three groups based on the timing of the initial treatment: Early, middle, and late periods defined as 2000 to 2005, 2006 to 2012, and 2013 to 2018, respectively. Results There were 132 (8.9%), 405 (17.5%), and 388 (22.2%) elderly patients in the early, middle, and late period, respectively, showing a significant increase over time (p < 0.001). In both elderly and non‐elderly patients, the median albumin‐bilirubin score significantly improved over time and the diagnosis of HCC was made slightly earlier over time. The median overall survival (OS) in elderly patients was 52.8, 42.0, and 45.6 months in the early, middle, and late period, respectively, without a significant improvement (p = 0.17) whereas the OS in non‐elderly patients was significantly improved (p < 0.001). The percentage of elderly patients receiving curative treatments did not significantly increase (p = 0.43), while that of non‐elderly patients did (p = 0.017). Non‐liver‐related death in elderly patients significantly differed among periods (p = 0.023), while liver‐related death did not (p = 0.050). Liver‐ and non‐liver‐related death in non‐elderly patients significantly differed among periods (p < 0.001, p = 0.005). Conclusions Survival in elderly patients was not improved despite an improvement in their liver function. Curative treatments should be conducted when appropriate after evaluating each elderly patient

Cabozantinib for Advanced Hepatocellular Carcinoma in the Latest Real-World Practice: A Multicenter Retrospective Analysis

Abstract Background Cabozantinib was found to be effective as a second- or third-line treatment after sorafenib in patients with advanced hepatocellular carcinoma (HCC) in the phase 3 CELESTIAL trial. So far, as immunotherapy has substituted molecular target agents as the primary systemic therapy for advanced HCC, cabozantinib is extensively used in the latest real-world clinical practice in a greatly different position than that shown by the CELESTIAL trial. In the current analysis, we examined the safety and effectiveness of cabozantinib administration in real-life settings for patients with advanced HCC. Methods We retrospectively obtained data from patients with advanced HCC who received cabozantinib in three institutions in Japan between 14 September 2018 and 30 November 2021. Results During the study period, 23 patients with advanced HCC received cabozantinib. Our cohort included 21.7% of patients with Child–Pugh class B, and 52.2% of patients in fourth line or later. The median progression-free survival of patients given cabozantinib was 3.7 months. Regarding patients with Child–Pugh class B or administration in fourth line or later, the discontinuation rate due to adverse events in patients who initialized at 40 or 20 mg was lower than those who initialized at 60 mg (42.9% versus 75.0%). Patients who were able to continue treatment with cabozantinib for more than 3 months were more likely to undergo dose reduction than those who did not (85.7% versus 25.0%). Conclusions Cabozantinib has recently been administered to a diverse range of patients, including those who were not enrolled in the CELESTIAL trial. Deliberate dose reduction could potentially offer clinical benefits to patients with impaired liver function. Furthermore, managing adverse events by reducing the dose could play a crucial role in extending the duration of treatment with cabozantinib.
