This study aimed to evaluate the effect of lenvatinib (LEN) combined with transcatheter intra-arterial therapy (TIT) for advanced-stage hepatocellular carcinoma (HCC) after propensity score matching (PSM). This retrospective study enrolled 115 patients with advanced-stage HCC who received LEN treatment. The patients were categorized into the LEN combined with TIT group ( n = 30) or the LEN monotherapy group ( n = 85). After PSM, 38 patients (LEN + TIT group, n = 19; LEN monotherapy group, n = 19) were analyzed. The median overall survival (OS) in the LEN + TIT group was significantly higher than that in the LEN monotherapy group (median survival time (MST): 28.1 months vs. 11.6 months, p = 0.014). The OS in the LEN combined with transcatheter arterial chemoembolization and LEN combined with hepatic arterial infusion chemotherapy groups was significantly higher than that in the LEN monotherapy group (MST 20.0 vs. 11.6 months, 30.2 vs. 11.6 months, p = 0.048, and p = 0.029, respectively). Independent factors associated with OS were alpha-fetoprotein and LEN combined with TIT. The indications for LEN combined with TIT were age <75 years and modified albumin bilirubin (m-ALBI) grade 1. We concluded that LEN combined with TIT may improve prognosis compared with LEN monotherapy in patients with advanced-stage HCC.

Background and Aims: We aimed to validate the predictive factors for tumor response and the prognostic impact of conversion therapy aimed at cancer- and drug-free states in patients with unresectable hepatocellular carcinoma (u-HCC) undergoing atezolizumab plus bevacizumab (Atez/Bev) therapy., Methods: This retrospective study enrolled 156 patients who were Child-Pugh class A with u-HCC treated using Atez/Beva. The profile of objective response was investigated using decision-tree analysis. Progression-free, recurrence-free, and overall survival were assessed., Results: The progression-free and overall survival were 6.1 and 18.0 months, respectively. Objective response and disease control rates were 32.0% and 84.0%, respectively. Decision-tree analysis revealed that neutrophil-to-lymphocyte ratio (NLR) <3, modified albumin-bilirubin grade (m-ALBI) 1 or 2a, and age < 75 were sequential splitting variables for the objective response, respectively. In the multivariate analysis, NLR <3 and m-ALBI grade 1 or 2a were identified as predictive factors for objective response. We successfully achieved eligibility for conversion therapy in 17 patients after Atez/Bev therapy significant response. Following conversion therapy, the curative therapy group, including surgical resection or radiofrequency ablation (RFA), had significantly higher recurrence-free survival than did the transcatheter arterial chemoembolization (TACE) and Atez/Bev discontinuation (surgical resection or RFA; not reached vs. TACE; 5.3 months, p = 0.008, Atez/Bev discontinuation; 3.9 months, p = 0.048, respectively) groups., Conclusions: NLR <3 and m-ALBI grade 1 or 2a were predictive factors for conversion therapy, leading to cancer- and drug-free states in patients with u-HCC undergoing Atez/Bev therapy. Moreover, surgery or RFA may be suitable for conversion therapy for cancer-free status., (© 2023 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.)

In 2013 and 2014, the development of microcatheters with balloons for the 4-Fr system and new embolization materials provided various options for transarterial chemoembolization (TACE), expanding the range of treatment strategies. At our hospital, balloon-occluded TACE (B-TACE), conventional TACE (C-TACE), and drug-eluting bead TACE (DEB-TACE) have been actively performed for hepatocellular carcinoma (HCC). This study compared the local recurrence-free (LRF) periods of nodules with complete necrosis (TE4) obtained using each treatment method by extracting the nodules evaluated as complete response by the modified Response Evaluation Criteria in Solid Tumors. We performed 580 TACE procedures between June 2013 and April 2019. Among them, 58 HCC nodules in 43 patients, 33 nodules in 30 patients, and 45 nodules in 25 patients were evaluated as having complete necrosis after C-TACE, DEB-TACE, and B-TACE, respectively. The time to local recurrence for each nodule was defined as the LRF period, and the quality of TE4 for each TACE was examined. Factors related to overall survival and the LRF period were determined by univariate and multivariate analyses, and overall survival and the LRF period were analyzed using the Kaplan-Meier method. Multivariate analysis of the LRF period showed that B-TACE was an independent factor. The median LRF periods were 39.3, 13, and 9.1 months for B-TACE, C-TACE, and DEB-TACE, respectively. Moreover, B-TACE had a significantly longer LRF period than C-TACE and DEB-TACE. Conclusion: There was no significant difference between C-TACE and DEB-TACE. The LRF period of nodules with TE4 was the longest with B-TACE, suggesting that B-TACE should be used to achieve a radical cure in patients with HCC., (© 2022 The Authors.

Background & Aims: Intermediate hepatocellular carcinoma (HCC) treatment has become complicated due to the development of various molecular-targeted agents (MTAs). We aimed to determine whether the administration of MTAs in patients with intermediate-stage HCC contributed to the prevention of progression to an advanced stage., Methods: We enrolled and retrospectively examined 289 patients with Child-Pugh class A who had been diagnosed with intermediate-stage HCC and underwent initial trans-arterial chemoembolization (TACE). Patients were classified into 2 groups: a group in which MTAs were administered to patients whose condition was refractory to TACE (n = 65) and a group in which MTAs were not administered (n = 65) at intermediate-stage HCC after propensity score matching (PSM). Time to stage progression (TTSP) and overall survival (OS) were calculated using the Kaplan-Meier method and analyzed using a log-rank test after PSM., Results: TTSP and OS of the group with MTA administration were significantly longer than those of the group without MTA administration (TTSP: 36.4 vs. 17.9 months, p < 0.001; median survival time [MST]: 44.6 vs. 26.6 months, p = 0.001). Within the up-to-seven criteria and administration of MTAs at the intermediate-stage HCC were identified as independent factors for TTSP and OS in the multivariate analysis. TTSP and OS in the era of the multi-MTA group were significantly longer than those in the era of the mono-MTA group (TTSP: 44.8 vs. 27.4 months, p = 0.01; MST: 53.4 vs. 33.3 months, p = 0.01)., Conclusion: The administration of MTAs in patients with intermediate-stage HCC contributes to the prevention of stage progression and prolongs OS., (© 2021 S.

Background and Aims: Conventional transcatheter arterial chemoembolization (C-TACE) and drug-eluting bead (DEB)-based TACE are current treatments for hepatocellular carcinoma (HCC). We compared the therapeutic efficacies and adverse events of these methods in a single-center retrospective cohort study., Methods: We enrolled 174 patients treated between January 2010 and October 2016; 98 and 76 underwent C-TACE and DEB-TACE, respectively, with 76 and 22 of the former group and 49 and 27 of the latter group classified as Child-Pugh class A and B, respectively. Therapeutic outcomes, progression-free survival (PFS), and adverse events were evaluated., Results: The PFS rates in the C-TACE and DEB-TACE groups were 8.1 and 6.1 months, respectively (p = 0.79). The response and disease control rates were 64 and 71% in C-TACE patients and 69 and 78% in DEB-TACE patients, respectively (p = 0.25). Postprocedural pain, vomiting, and fever were more frequent following C-TACE than DEB-TACE (p < 0.001). In contrast, the incidences of bilomas and arterio-portal shunts were significantly higher following DEB-TACE (p < 0.001); the incident rates of arterio-portal shunt formation were 8.1 and 48.7% in patients undergoing C-TACE and DEB-TACE, respectively. Child-Pugh class A was significantly associated with arterio-portal shunt formation after DEB-TACE on multivariate analysis., Conclusions: There were no significant differences in the therapeutic efficacies of C-TACE and DEB-TACE. However, the frequency of arterio-portal shunt formation was significantly higher in HCC patients with Child-Pugh class A undergoing DEB-TACE. Our findings imply that C-TACE should be selected for HCC patients with Child-Pugh class A and DEB-TACE should be chosen for those with Child-Pugh class B., (© 2020 S. Karger AG, Basel.)

Background: Transcatheter arterial chemoembolization (TACE) is a standard therapy used in the treatment of intermediate hepatocellular carcinoma (HCC). Recently, balloon-occluded TACE (B-TACE) has been developed., Purpose: This study aimed to clarify the effects of B-TACE in patients with HCC, with a focus on which drug is suitable to suspend in Lipiodol for B-TACE., Methods: We retrospectively evaluated 35 patients with HCC treated with B-TACE. Factors associated with enhanced time to progression (TTP) after B-TACE were evaluated using univariate and multivariate analyses., Results: A total of 35 patients with HCC (40 nodules) were treated with B-TACE between June 2013 and August 2016. Epirubicin was used in 25 nodules and miriplatin was used in 15 nodules. Epirubicin (15.1 months) was significantly better than miriplatin (3.2 months) in prolonging the local TTP after B-TACE (p = 0.0293). Epirubicin showed a positive tendency in TE4 (100% tumor necrosis) rate when compared with miriplatin (p = 0.058). Achievement of TE4 was the only significant factor associated with better TTP after B-TACE. Epirubicin- and TACE-naïve statuses were significant factors in achieving TE4 with B-TACE., Conclusion: To enhance the TTP with B-TACE, TE4 should be achieved. Epirubicin is a more optimal anticancer drug (as a Lipiodol suspension) than miriplatin for achieving TE4 with B-TACE., (© 2018 S. Karger AG, Basel.)

Purpose: Portal vein tumor thrombosis is a critical complication in patients with hepatocellular carcinoma (HCC). This prospective multicenter trial assessed the efficacy of hepatic arterial infusion chemoembolization therapy with cisplatin suspended in lipiodol combined with 5-fluorouracil for HCC patients with portal vein tumor thrombosis., Methods: We enrolled 52 HCC patients with portal vein tumor thrombosis. They received hepatic arterial infusion chemoembolization therapy with cisplatin suspension in lipiodol and 5-fluorouracil. The primary efficacy endpoint was progression-free survival (PFS), while the secondary endpoints were overall survival (OS), tumor response rate, safety, and tolerability. Independent factors for survival were also evaluated., Results: The median PFS and OS were 8.6 and 27.0 months, respectively. Ten patients showed complete response, while 29 had partial response (response rate, 75.0 %). The median survival time of 10 patients with complete response and 29 with partial response was 32 months, while that of 15 patients with partial response who later showed disappearance of HCC following additional therapies was 50 months. Multivariate analysis identified response to treatment and disappearance of viable HCC as independent predictors of survival. The treatment was well tolerated, and the only encountered Grade 3 toxicities were thrombocytopenia and hyperbilirubinemia., Conclusions: Hepatic arterial infusion chemoembolization therapy with cisplatin suspension in lipiodol combined with 5-fluorouracil is effective treatment for unresectable HCC with portal vein tumor thrombosis.
