We sought to investigate the clinical profile(s) associated with the discontinuation of lenvatinib (LEN) due to severe adverse events (DLSAE) in patients with unresectable hepatocellular carcinoma (HCC). This retrospective study enrolled 177 patients with HCC treated with LEN. Independent factors associated with DLSAE were advanced age, albumin-bilirubin (ALBI) grade 2, fatigue grade ≥ 3, and appetite loss ≥ 2. The overall survival (OS) in the group that did not require DLSAE was significantly longer compared to the group that did require DLSAE (median survival time (MST): not reached vs. 12.8 months, p < 0.001). Moreover, advanced age was the most important variable for DLSAE in a decision tree analysis. Hypertension and hand-foot-skin-reaction (HFSR) were also significantly associated with longer survival, and the occurrence of hypertension was the earliest predictor for improved prognosis, while appetite loss and development of grade ≥ 3 fatigue were predictive of a poor prognosis. We concluded that the appearance of hypertension has potential as an early surrogate marker to predict improved prognosis. Moreover, careful management to avoid discontinuation of treatment leads to longer survival in patients receiving LEN.

We aimed to evaluate the impact of alternating lenvatinib (LEN) and trans-arterial therapy (AT) in patients with intermediate-stage hepatocellular carcinoma (HCC) after propensity score matching (PSM). This retrospective study enrolled 113 patients with intermediate-stage HCC treated LEN. Patients were classified into the AT (n = 41) or non-AT group (n = 72) according to the post LEN treatment. Overall survival (OS) was calculated using the Kaplan–Meier method and analyzed using a log-rank test after PSM. Factors associated with AT were evaluated using a decision tree analysis. After PSM, there were no significant differences in age, sex, etiology, or albumin-bilirubin (ALBI) score/grade between groups. The survival rate of the AT group was significantly higher than that of the non-AT group (median survival time; not reached vs. 16.3 months, P = 0.01). Independent factors associated with OS were AT and ALBI grade 1 in the Cox regression analysis. In the decision tree analysis, age and ALBI were the first and second splitting variables for AT. In this study, we show that AT may improve prognosis in patients with intermediate-stage HCC. Moreover, alternating LEN and trans-arterial therapy may be recommended for patients below 70 years of age with ALBI grade 1.

Background: Although lenvatinib has become the standard therapy for hepatocellular carcinoma (HCC), the high incidence rate of adverse events (AEs) is an issue. This study aimed to clarify the AEs of lenvatinib and the therapeutic impact of five days-on/two days-off administration (i.e., weekends-off strategy) for lenvatinib. Methods: We retrospectively assessed the therapeutic effects and AEs of 135 patients treated with lenvatinib, and the improvement of tolerability and therapeutic efficacy of 30 patients treated with the weekends-off strategy. We also evaluated lenvatinib-induced vascular changes in tumors and healthy organs using a mouse hepatoma model. Results: The incidence rates of any grade and grade ≥ 3 AEs were 82.1% and 49.6%. Fatigue was the most important AE since it resulted in dose reduction and discontinuation. Of the 30 patients who received weekends-off lenvatinib, 66.7% tolerated the AEs. Although 80.8% of the patients showed progression after dose reduction, the therapeutic response improved in 61.5% of the patients by weekends-off lenvatinib. Notably, weekends-off administration significantly prolonged the administration period and survival (p < 0.001 and p < 0.05). The mouse hepatoma model showed that weekends-off administration contributed to recovery of vascularity in the organs. Conclusion: Weekends-off administration of lenvatinib was useful to recover the therapeutic response and tolerability toward AEs.

Abstract. Although sorafenib and hepatic arterial infusion chemotherapy (HAIC) have been proven to improve prognosis in hepatocellular carcinoma (HCC) patients with macroscopic vascular invasion (MVI), the most appropriate approach remains unclear. The present multicenter, non-randomized, prospective cohort study aimed to compare the efficacy and safety of HAIC and sorafenib in patients with advanced HCC and MVI, without extra-hepatic spread (EHS) and Child-Pugh class A disease. The present study was performed between April 2008 and March 2014, and 64 HCC patients with MVI, without EHS and Child-Pugh class A disease were registered. Of these patients, 44 were treated with HAIC and 20 with sorafenib. HAIC involved cisplatin (50 mg fine powder in 5-10 ml lipiodol) and a continuous infusion of 5-fluorouracil (FU) (1,500 mg/5 days), which is referred to as new 5-FU and cisplatin therapy (NFP). The primary outcome was progression-free survival, and the secondary outcome was overall survival (OS). Clinical factors influencing OS and the therapeutic effect were identified using univariate and multivariate analyses. There were no differences in clinical factors between the two groups. The median progression-free survival was 5.1 and 9.5 months in the sorafenib and NFP groups, respectively (P=0.001). The complete response (CR) or partial response (PR) rates were 10 and 71% in the sorafenib and NFP groups, respectively (P<0.001). The median OS in the sorafenib and NFP groups was 13.2 and 30.4 months, respectively (P=0.013). Multivariate analysis revealed that the independent predictors of survival were Child-Pugh score (5, P=0.022, 95% CI,, grade of portal vein invasion (brunch, P=0.009, 95% CI, 0.220-0.752), and therapeutic effect (CR or PR, P<0.001, 95% CI, 0.220-0.752), and the independent predictor of therapeutic effect was therapeutic regimen (NFP, P<0.001, 95% CI,. NFP should be the first choice for patients with advanced HCC and MVI, without EHS and Child-Pugh A disease.

The Kurume Liver Cancer Study Group of Japan Sorafenib and lenvatinib, as molecular-targeted agents, constitute effective primary treatment options for advanced hepatocellular carcinoma (HCC). However, the choice of optimal primary treatment agent remains controversial. Here, we aimed to assess the respective outcomes between these agents as primary treatment in patients with advanced HCC through use of propensity score-matching analysis (PSMA). We enrolled 670 consecutive patients who were diagnosed with advanced HCC and received sorafenib (n = 524) or lenvatinib (n = 146) as the primary treatment among 18 participating institutions between May 2009 and October 2019. To reduce confounding, we used PSMA regarding seven variables related to advanced HCC prognosis, resulting in the selection of 292 patients (n = 146 for each agent). Following PSMA, no significant difference was observed in the outcome of overall survival time between patients treated with sorafenib or lenvatinib (median survival time 15.3 or 14.9 months, respectively; P = 0.2358). Patients treated with lenvatinib exhibited significantly greater therapeutic effects (response rate: 5% and 31%; disease control rate: 46% and 69% for sorafenib and lenvatinib, respectively; P < 0.0001), but showed significantly lower probability of transition to secondary treatment (sorafenib, 60%; lenvatinib, 45%; P < 0.0269) and higher any adverse events rate (sorafenib, 86%; lenvatinib, 95%; P = 0.0207). Conclusion: As a primary molecular-targeted agent-based treatment for advanced HCC, our findings suggested that sorafenib is generally appropriate as it offers significantly lower frequency of adverse events and higher probability of transition to secondary treatment, in consideration of the enhanced postprogression survival mediated by sequential treatment. Alternatively, lenvatinib affords a significantly higher therapeutic effect and should be used when immediate tumor reduction is required. (Hepatology Communications 2020;4:1218-1228). S ignificant progress has been made regarding treatments for hepatocellular carcinoma (HCC), particularly in hepatic resection, percutaneous radiofrequency ablation, transcatheter arterial chemoembolization, hepatic arterial infusion chemotherapy, radiation therapy, and liver transplantation. (1,2) In addition, the treatment landscape for advanced HCC has also changed dramatically with the approval of molecular-targeted agents (MTAs) such as sorafenib and lenvatinib. (3-5

Background: Atezolizumab plus bevacizumab was approved for patients with hepatocellular carcinoma (HCC). Although clinical trials have revealed its efficacy, the outcomes in the real-world clinical practice are unclear. We retrospectively evaluated the efficacy and safety of atezolizumab plus bevacizumab for HCC. Materials and Methods: This is a multicenter study conducted between November 2020 and March 2021. Among the 61 patients, 51 were assessed for progression-free survival (PFS), therapeutic response, and adverse events (AEs). Results: The median PFS was 5.4 months. The objective response rate (ORR) was 35.3%. The disease control rate (DCR) was 86.3%. The incidence rates of AEs at any grade and grade >3 were 98.0% and 29.4%, respectively. The most frequent AE at any grade and grade >3 was hepatic disorder. In patients with a previous history of molecular targeted agent (MTA) or the degree of albumin-bilirubin (ALBI) grade, there were no significant differences in the PFS, ORR, DCR, and incidence rates of AEs. Conclusion: The study demonstrated that atezolizumab plus bevacizumab was effective and safe for patients with HCC even in the real-world setting including patients with a previous MTA history or other than ALBI grade 1.

Aims The prognosis of hepatocellular carcinoma (HCC) patients treated with transcatheter arterial chemoembolization (TACE) is still poor. We aimed to evaluate the impact of TACE combined with radiofrequency ablation (TACE+RFA) on the prognosis of HCC patients using decision‐tree analysis after propensity score matching. Methods This was a retrospective study. We enrolled 420 patients with HCC treated with TACE alone (n = 311) or TACE+RFA (n = 109) between 1998 and 2016 (median age, 72 years; male / female, 272/148; Barcelona Clinic Liver Cancer (BCLC) stage A / B, 215/205). The prognosis of patients who underwent TACE+RFA was compared to patients who underwent TACE alone after propensity score matching. Decision‐tree analysis was used to investigate the profile for prognosis of the patients. Results After propensity score matching, there was no significant difference in age, sex, BCLC stage, or albumin–bilirubin (ALBI) score between both groups. The survival rate of the TACE+RFA group was significantly higher than the TACE alone group (median survival time [MST] 57.9 months vs. 33.1 months, P < 0.001). In a stratification analysis according to BCLC stage, the overall survival rate of the TACE+RFA group was significantly higher than the TACE alone group in BCLC stage A and B (MST 57.9 and 50.7 months vs. 39.8 and 24.5 months [P = 0.007 and 0.001], respectively). Decision‐tree analysis showed that TACE+RFA was the third distinguishable factor for survival in patients with α‐fetoprotein level >7 ng/mL and ALBI <−2.08. Conclusion Decision‐tree analysis after propensity score matching showed that TACE+RFA could prolong the survival of HCC patients compared to TACE alone.
