Transarterial chemoembolization with/without immune checkpoint inhibitors plus tyrosine kinase inhibitors for unresectable hepatocellular carcinoma: a single center, propensity score matching real-world study

ObjectivesTo explore the efficacy and safety of Transarterial chemoembolization (TACE) in combination with immune checkpoint inhibitors (ICIs) and tyrosine kinase inhibitors (TKIs) in patients with unresectable hepatocellular carcinoma (uHCC).Methods456 patients with HCC receiving either TACE in combination with ICIs and TKIs (combination group, n = 139) or TACE monotherapy (monotherapy group, n = 317) were included from Apr 2016 to Dec 2021 in this retrospective study. We employed propensity score matching (PSM), performed 1:2 optimal pair matching, to balance potential bias.ResultsThe mean follow-up time is 24.7 months (95% CI 22.6–26.8) for matched patients as of March 2022. After matching, the combination group achieved longer OS and PFS (median OS:21.9 vs. 16.3 months, P = 0.022; median PFS: 8.3 vs. 5.1 months, P < 0.0001) than TACE monotherapy group. The combination group had better objective response rate (ORR) and disease control rate (DCR) (ORR: 52.5% vs. 32.8%, P < 0.001; DCR: 82.7% vs. 59.6%, P < 0.001). Subgroup analysis showed that patients who received “TKIs + ICIs” after the first TACE procedure (after TACE group) achieved longer OS than those before the first TACE procedure (before TACE group) (26.8 vs. 19.2 months, P = 0.011). Adverse events were consistent with previous studies of TACE-related trials.ConclusionsTACE plus TKIs and ICIs appeared to deliver longer PFS and OS in HCC patients than TACE monotherapy. “TKIs + ICIs” co-treatment within 3 months after the first TACE procedure might be a better medication strategy.

Efficiency and Stability of Transarterial Chemoembolization Combined With or Without Lenvatinib for Unresectable Hepatocellular Carcinoma.

At present, there are relatively few reports on the treatment consisting of transarterial chemoembolization (TACE) combined with lenvatinib, and there is no unified conclusion on the curative effect. The objective of this research was to assess the efficacy and safety of combining TACE with lenvatinib for the treatment of unresectable hepatocellular carcinoma (uHCC). This study was a retrospective analysis of the patient's medical records. In this study, 249 patients (uHCC) in our hospital from 2020 to 2021 were divided into 2 groups, including the TACE-alone group (198 patients received TACE alone) and the TACE-LEN group (51 patients were treated with TACE combined with lenvatinib). According to the propensity score matching method, there were TACE-LEN group (51 patients) and TACE-alone group (51 patients). With the help of surgical experts, the overall survival (OS), progression-free survival (PFS), and tumor response (according to mRECIST) of the 2 groups were sorted and recorded, and then analyzed. Survival curves were established, the prognostic factors of OS and PFS were analyzed by univariate and multivariate analyses, and the independent prognostic factors were recorded. The adverse reactions of patients after treatment were recorded. The 1-year and 2-year OS rates were 50.98% and 19.48% for the TACE-LEN group, 27.45% and 8.55% for the TACE-alone group (P = .042), respectively. The PFS of patients in the TACE-LEN group was also longer (1-year PFS rate: 25.49% vs. 11.76%, 2-year PFS rate: 19.17% vs. 5.88%; P = .0069). The disease control rate (68.63% vs. 49.10%, P = .044) of the TACE-LEN group was significantly higher. In the subgroup analysis, the OS of the TACE-LEN group was better than TACE-alone group in patients with Barcelona Clinic Liver Cancer stage C (1-year OS rate: 44.44% vs. 17.14%, 2-year OS rate: 8.67% vs. 0%; P = .009). Factor analysis concluded that serum alkaline phosphatase and treatment protocol (TACE-LEN vs. TACE) were independent influencing factors of OS. The most common treatment-related AEs included decreased albumin (n = 28, 54.9%), hypertension (n = 23, 45.1%), elevated aspartate transaminase (n = 21, 41.2%) and elevated total bilirubin (n = 18, 35.2%) in TACE-LEN group. Compared with TACE monotherapy, TACE combined with lenvatinib effectively prolonged the OS time with a controllable safety profile for patients with uHCC.

TACE plus lenvatinib and tislelizumab for intermediate-stage hepatocellular carcinoma beyond up-to-11 criteria: a multicenter cohort study.

Intermediate-stage (BCLC-B) hepatocellular carcinoma (HCC) beyond the up-to-11 criteria represent a significant therapeutic challenge due to high and heterogeneous tumor burden. This study evaluated the effectiveness and safety of transarterial chemoembolization (TACE) in combination with lenvatinib and tislelizumab for these patients. In this retrospective cohort study, patients with unresectable intermediate-stage HCC beyond the up-to-11 criteria were enrolled and divided into TACE monotherapy (T), TACE combined with lenvatinib (TL), or TACE plus lenvatinib and tislelizumab (TLT) group based on the first-line treatment, respectively. The primary endpoint was overall survival (OS). The secondary outcomes included progression-free survival (PFS), tumor response according to RESIST1.1 and modified RECIST, and adverse events (AEs). There were 38, 45, and 66 patients in the T, TL, and TLT groups, respectively. The TLT group exhibited significantly higher ORR and DCR than the other two groups, as assessed by either mRECIST or RECIST 1.1 (all P<0.05). Median PFS and OS were significantly longer in the TLT group compared with the T group (PFS: 8.5 vs. 4.4 months; OS: 31.5 vs. 18.5 months; all P<0.001) and TL group (PFS: 8.5 vs. 5.5 months; OS: 31.5 vs. 20.5 months; all P<0.05). The incidence of TRAEs was slightly higher in the TLT and TL groups than in the T group, while all the toxicities were tolerable. No treatment-related death occurred in all groups. TACE combined with lenvatinib and tislelizumab significantly improved the survival benefit compared with TACE monotherapy and TACE plus lenvatinib in patients with intermediate-stage HCC beyond the up-to-11 criteria, with an acceptable safety profile.

A retrospective study of transarterial chemoembolization (TACE) combined with lenvatinib compared with TACE monotherapy for BCLC B2 stage hepatocellular carcinoma.

The present study aimed to compare the efficacy and safety of combination therapy with lenvatinib (Len) plus transarterial chemoembolization (TACE) and TACE alone in patients with Barcelona Clinic Liver Cancer (BCLC) B2 stage hepatocellular carcinoma (HCC). A total of 66 patients with BCLC B2 stage HCC were retrospectively reviewed in the present study, of which 34 patients received Len + TACE, while 32 patients received TACE alone between May 2018 and May 2020. Survival outcome, tumor response and adverse events (AEs) were compared between the two treatment groups. The 6-month, 1- and 2-year overall survival (OS) rates were significantly higher in the Len + TACE group (97.1, 85.3 and 76.3%, respectively) compared with those in the TACE group [(93.8, 81.1 and 45.4%, respectively); hazard ratio (HR), 0.395; 95% confidence interval (CI), 0.180-0.867; P=0.023], but no significant difference in progression-free survival rate was observed between the two groups (HR, 0.815; 95% CI, 0.437-1.520; P=0.510). Patients receiving Len + TACE demonstrated a higher objective response rate compared with those receiving TACE alone (64.7 vs. 34.4%; P=0.014). Therefore, Len + TACE combination therapy was associated with increased OS and tumor response compared with that of TACE monotherapy in patients with BCLC B2 stage HCC. However, large-scale, multicenter, prospective studies are needed to further confirm these results.

Transarterial Chemoembolization for Patients with Unresectable Hepatocellular Carcinoma with Child-Pugh B7.

This study aimed to evaluate the efficacy and safety of transarterial chemoembolization (TACE) in patients with unresectable early or intermediate hepatocellular carcinoma (HCC) and Child-Pugh (CP)-B liver dysfunction. This multicenter retrospective study enrolled patients with treatment-naïve HCC treated with TACE monotherapy between January 2012 and December 2020 at six Chinese hospitals. The primary outcome was overall survival (OS), and the secondary outcomes included the objective response rate (ORR) according to the modified RECIST and adverse events (AEs). Propensity score matching (PSM) was performed to reduce bias between the CP-B and CP-A groups. A total of 847 patients were included in the study. CP-A patients had significantly longer OS (median, 22.0 vs 19.3 months, P = 0.032) than CP-B (score of 7-9) patients, but a non-significant trend compared with CP-B (score of 7) patients (median, 22.0 vs 20.5 months, P = 0.254). After PSM, the median OS was 22.7 months for CP-A patients, while it was 19.3 months for CP-B (score of 7-9) patients (p = 0.026) and 20.5 months for CP-B (score of 7) patients (p = 0.155). CP-A patients achieved a significantly better ORR (53.0% vs 35.8%, P < 0.05) compared to CP-B (score of 7-9) patients, but a non-significant trend was observed in CP-B (score of 7) patients (53.0% vs 51.1%, P > 0.05). The post-embolization syndrome rates in the CP-A and CP-B (score of 7) cohorts were 52.1% and 53.3%, respectively. No new safety concerns were observed. Patients with HCC with a CP score of 7 receiving TACE showed a similar prognosis and safety profile to CP-A patients.

Real-world efficacy and safety of TACE plus camrelizumab and apatinib in patients with HCC (CHANCE2211): a propensity score matching study

ObjectivesThis study aimed to investigate the efficacy and safety of transarterial chemoembolization (TACE) plus camrelizumab, a monoclonal antibody targeting programmed death-1, and apatinib for patients with intermediate and advanced hepatocellular carcinoma (HCC) in a real-world setting.MethodsA total of 586 HCC patients treated with either TACE plus camrelizumab and apatinib (combination group, n = 107) or TACE monotherapy (monotherapy group, n = 479) were included retrospectively. Propensity score matching analysis was used to match patients. The overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and safety in the combination group were described in comparison to monotherapy.ResultsAfter propensity score matching (1:2), 84 patients in the combination group were matched to 147 patients in the monotherapy group. The median age was 57 years and 71/84 (84.5%) patients were male in the combination group, while the median age was 57 years with 127/147 (86.4%) male in the monotherapy group. The median OS, PFS, and ORR in the combination group were significantly higher than those in the monotherapy group (median OS, 24.1 vs. 15.7 months, p = 0.008; median PFS, 13.5 vs. 7.7 months, p = 0.003; ORR, 59.5% [50/84] vs. 37.4% [55/147], p = 0.002). On multivariable Cox regression, combination therapy was associated with significantly better OS (adjusted hazard ratio [HR], 0.41; 95% confidence interval [CI], 0.26–0.64; p < 0.001) and PFS (adjusted HR, 0.52; 95% CI, 0.37–0.74; p < 0.001). Grade 3 or 4 adverse events occurred in 14/84 (16.7%) and 12/147 (8.2%) in the combination and monotherapy groups, respectively.ConclusionsTACE plus camrelizumab and apatinib showed significantly better OS, PFS, and ORR versus TACE monotherapy for predominantly advanced HCC.Clinical relevance statementCompared with TACE monotherapy, TACE plus immunotherapy and molecular targeted therapy showed better clinical efficacy for predominantly advanced HCC patients, with a higher incidence of adverse events.Key Points• This propensity score–matched study demonstrates that TACE plus immunotherapy and molecular targeted therapy have a longer OS, PFS, and ORR compared with TACE monotherapy in HCC.• Grade 3 or 4 adverse events occurred in 14/84 (16.7%) patients treated with TACE plus immunotherapy and molecular targeted therapy compared with 12/147 (8.2%) patients in the monotherapy group, while no grade 5 adverse events were observed in all cohorts.

Transarterial chemoembolization with or without multikinase inhibitors for patients with unresectable hepatocellular carcinoma: a systematic review and meta-analysis of randomized controlled trials

Background Randomized controlled trials (RCTs) testing the combination therapy of transarterial chemoembolization (TACE) plus multikinase inhibitor (MKI) in patients with unresectable hepatocellular carcinoma (HCC) have yielded inconsistent results. Methods In this work, a systematic review and meta-analysis was performed to compare the TACE+MKI combination therapy versus TACE monotherapy in HCC patients with time to progression (TTP) adopted as primary outcome. Results A total of 10 RCTs comprising 2837 patients receiving combination therapy (TACE plus sorafenib, brivanib, orantinib or apatinib) were included. TACE+MKI significantly prolonged TTP (hazard ratio [HR] 0.74, 95% CI 0.62-0.89, p=0.001) versus TACE monotherapy. Subgroup analysis suggested MKI administration before TACE might be preferable to post-TACE MKI for TTP. TACE+MKI also increased objective response rate (ORR) (risk ratio [RR] 1.17, 95% CI 1.03-1.32, p=0.01), but failed to improve overall survival (OS) (HR 0.98, 95% CI 0.86-1.13, p=0.82) and progression-free survival (PFS) (HR 0.75, 95% CI 0.50-1.12, p=0.16). The incidence of any adverse event (AE) did not significantly differ between TACE+MKI and TACE groups (RR 1.17, 95% CI 0.96-1.42, p=0.01), while serious AEs showed significant difference (RR 1.41, 95% CI 1.26-1.59, p&amp;lt;0.0001). Nevertheless, these AEs showing significant difference were mainly associated with MKI toxicities rather than TACE. Conclusions TACE+MKI combination therapy improved TTP and ORR but not OS and PFS in patients with unresectable HCC. Further high-quality trials are needed to verify these clinical benefits, and our findings could be very informative for future trial design.

Efficacy and safety of donafenib combined with transarterial chemoembolization (TACE) for treating intermediate/advanced-stage hepatocellular carcinoma (HCC): A retrospective real-world study.

e16146 Background: TACE is well-recognized as the mainstay treatment for intermediate-stage HCC; however, the efficacy of TACE monotherapy has been unsatisfactory in advanced-stage HCC. Donafenib is a novel multi-kinase inhibitor approved for first-line treatment of advanced-stage HCC. Herein, we evaluated the efficacy and safety of donafenib combined with TACE for treating intermediate/advanced-stage HCC. Methods: We collected clinical data of patients (pts) with unresectable HCC who had a Child-Pugh class A/B and were admitted for donafenib and TACE combination therapy at The First Affiliated Hospital of USTC between October 2021 to October 2022. Pts had at least one measurable lesion determined using mRECIST criteria. Pts with complete baseline information and at least one follow-up evaluation were incorporated in the final analysis, including the objective response rate (ORR), disease control rate (DCR), and adverse events (AEs) by CTCAE 5.0. The last follow-up time was January 1, 2023. Results: In total, 109 pts were enrolled (80.3% males, mean age 60.5 years, 86.2% ECOG of 1, 92.7% HBV positive, 53.2% BCLC stage B, 46.8% BCLC stage C, 31.2% baseline AFP≥400 μg/L, 39.5% with portal vein tumor thrombus). Among them, 54 pts (49.5%) received donafenib combined with TACE as first-line treatment, 8 (7.3%) as second-line treatment, and 47 (43.2%) with concurrent immunotherapy. At the time of data cut-off, the median follow-up time was 6.2 months, and 67 pts (61.5%) had ongoing donafenib treatment. The mean duration of treatment (DOT) with donafenib was 6.0 months, and the longest DOT was 12 months. Considering efficacy, 30 pts (27.5%) achieved complete response, 54 (49.5%) achieved partial response, 17 (15.6%) had stable disease, and 8 (7.4%) had progressive disease. The ORR and DCR were 77.1% and 92.7%, respectively. The ORRs of the first-, second-, and combination immunotherapy groups were 77.8% (42/54), 50.0% (4/8), and 80.9% (38/47), respectively. The DCRs were 92.6% (50/54), 100% (8/8), and 91.5% (43/47), respectively. Median progression-free survival was not reached. In terms of safety, 89 pts (81.7%) had AEs. The incidence of ≥grade 3 AEs was 17.4% (19/109), and the incidence of drug withdrawal due to AEs was 4.6% (5/109). The most common AEs were diarrhea (31.2%), hand-foot syndrome (29.4%), fatigue (25.7%), rash (15.6%), nausea (10.1%), and xerostomia (4.6%). The incidences of ≥grade 3 AEs in the first-, second-, and combination immunotherapy groups were 14.8% (8/54), 12.5% (1/8), and 17.0% (8/47), respectively. The combination immunotherapy group exhibited a high incidence of AEs. Conclusions: Satisfactory disease control was achieved in pts with different treatment durations after receiving donafenib combined with TACE, along with favorable safety and tolerability.

Interventional oncological treatment of breast cancer liver metastasis (BCLM): single center long-term evaluation over 26 years using thermoablation techniques like LITT, MWA and TACE in a multimodal application

The purpose of the study is to retrospectively evaluate the development and technological progress in local oncological treatments of patients with breast cancer liver metastasis (BCLM) using LITT (laser interstitial thermotherapy), MWA (microwave ablation) and TACE (transarterial chemoembolization) ablation techniques in a multimodal application. The study uses data generated between 1993 and 2020. Therapy results were evaluated using the Kaplan–Meier survival estimate, Cox proportional hazard regression and log-rank test. Cox regression analysis showed that the different treatment methods are statistically significant predictors of survival of patients. Median survival times for groups treated with LITT (212 patients) and LITT + TACE (215 patients) were 2.2 years and 2.1 years respectively; median survival times for groups treated with MWA (17 patients) and MWA + TACE (143 patients) were 5.6 and 2.4 years respectively. For LITT only treatments, the 1-, 3- and 5-year survival probability scored 80%, 37%, 22%. Results for combined LITT + TACE treatments were 76%, 34% and 15%. In group MWA, the 1-/3-/5-year survival probability rates were calculated as 89%, 89%, 89% (however, they should be interpreted carefully due to a relatively small sample size of n = 17 patients). Group MWA + TACE offered values of 77%, 38% and 22%. A separate group of 549 patients was analyzed with TACE monotherapy treatment. The estimated median survival time in this group was 0.8 years. The 1-/3-/5-year survival probability rates were 37%, 8% and 4%. Treatments with combined MWA and MWA + TACE resulted in the best median survival time estimations in this study.

Interventional oncological treatment of hepatocellular carcinoma (HCC) - A single-center long-term evaluation of thermoablation techniques like LITT, MWA, and TACE in a multimodal application over 26 years

PurposeThe purpose of the study is to retrospectively evaluate the development and technological progress in local oncological treatments of hepatocellular carcinoma (HCC) by means of ablation techniques like laser interstitial thermal therapy (LITT), microwave ablation (MWA) and transarterial chemoembolization (TACE) in a multimodal application.MethodThis retrospective single-center study uses data generated between 1993 and 2020 (1,045 patients). Therapy results are evaluated using survival rates of Kaplan-Meier estimator, Cox proportional hazard regression and log-rank test.ResultsMedian survival times in group LITT (25 patients) are 1.6 years, and, 2.6 years for LITT + TACE (67 patients). For LITT only treatments 1-/3-/5-year survival rates scored 64%, 24% and 20%. Results for combined LITT + TACE treatments were 84%, 37% and 14%. Median survival time in group MWA (227 patients) is 4.5 years. Estimated median survival time for MWA + TACE (108 patients) leads to a median survival time of 2.7 years. In group MWA the 1-/3-/5-year survival rates are 85%, 54%, 45%. Group MWA + TACE shows values of 79%, 41% and 25%. A separate group of 618 patients has been analyzed with TACE as monotherapy. Median survival time of 1 year was estimated in this group. 1-/3-/5-year survival rates are 48%, 15% and 8%. - Cox regression analysis showed that the different treatment methods are statistically significant predictors for survival of patients.ConclusionsTreatments with MWA resulted in best median survival rates, followed by MWA + TACE in combination. Survival rates of MWA only are significantly higher vs. LITT, vs. LITT + TACE and vs. TACE monotherapy.

Transarterial chemoembolization with PD-(L)1 inhibitors plus molecular targeted therapies for hepatocellular carcinoma (CHANCE001)

There is considerable potential for integrating transarterial chemoembolization (TACE), programmed death-(ligand)1 (PD-[L]1) inhibitors, and molecular targeted treatments (MTT) in hepatocellular carcinoma (HCC). It is necessary to investigate the therapeutic efficacy and safety of TACE combined with PD-(L)1 inhibitors and MTT in real-world situations. In this nationwide, retrospective, cohort study, 826 HCC patients receiving either TACE plus PD-(L)1 blockades and MTT (combination group, n = 376) or TACE monotherapy (monotherapy group, n = 450) were included from January 2018 to May 2021. The primary endpoint was progression-free survival (PFS) according to modified RECIST. The secondary outcomes included overall survival (OS), objective response rate (ORR), and safety. We performed propensity score matching approaches to reduce bias between two groups. After matching, 228 pairs were included with a predominantly advanced disease population. Median PFS in combination group was 9.5 months (95% confidence interval [CI], 8.4–11.0) versus 8.0 months (95% CI, 6.6–9.5) (adjusted hazard ratio [HR], 0.70, P = 0.002). OS and ORR were also significantly higher in combination group (median OS, 19.2 [16.1–27.3] vs. 15.7 months [13.0–20.2]; adjusted HR, 0.63, P = 0.001; ORR, 60.1% vs. 32.0%; P < 0.001). Grade 3/4 adverse events were observed at a rate of 15.8% and 7.5% in combination and monotherapy groups, respectively. Our results suggest that TACE plus PD-(L)1 blockades and MTT could significantly improve PFS, OS, and ORR versus TACE monotherapy for Chinese patients with predominantly advanced HCC in real-world practice, with an acceptable safety profile.

Efficacy of lenvatinib combined with sequential transarterial chemoembolization for primary hepatocellular carcinoma and the effects on serum basic fibroblast growth factor and vascular endothelial growth factor.

Objective: The aim of this research was to investigate the therapeutic efficacy of lenvatinib combined with sequential transarterial chemoembolization (TACE) on primary hepatocellular carcinoma (HCC) and the effects on serum basic fibroblast growth factor (bFGF) and vascular endothelial growth factor (VEGF). Method: A total of 104 patients with primary HCC, admitted to People's Hospital of Leshan from April 2018 to January 2021, were selected as the study subjects and were divided into the TACE-LEN group (n = 53) who were treated with lenvatinib combined with sequential TACE and the TACE group (n = 51) who were treated with TACE alone, according to the appropriate treatment modalities. The clinical efficacy 8weeks after treatment; the serum levels of total bilirubin, conjugated bilirubin, and alanine aminotransferase (ALT); the prothrombin time (PT); the indocyanine green retention rate at 15min (ICGR15); and the serum bFGF and VEGF levels before treatment and at 8weeks after treatment were compared between the two groups. The incidence of adverse events and the survival rates at 18 months were also recorded for both groups. COX regression analysis was used to analyze the risk factors affecting the survival of patients. Results: Eight weeks after treatment, the objective response rate was higher in the TACE-LEN group than in the TACE group (77.36% vs. 56.36%, p < 0.05), but there were no statistically significant differences in the bilirubin and ALT levels, the PT, and the ICGR15 between the two groups (p > 0.05). The serum bFGF and VEGF levels post-therapeutic were lower in the TACE-LEN group than in the TACE group (p < 0.05). The differences in the incidence of postoperative adverse events and the survival rate within 6months were not statistically significant between the two groups (p > 0.05). In addition, the survival rates within 12 and 18months after treatment were higher in the TACE-LEN group than in the TACE group than in the TACE group (81.1% vs. 64.7%, 69.8% vs. 49.1%, p < 0.05). ICG-R15 and treatment regimen are risk factors for survival. Conclusion: The worse the liver reserve is, the worse the prognosis is. The combination of TACE and lenvatinib showed better efficacy and longer survival than TACE monotherapy for HCC patients and reduced the levels of bFGF and VEGF.

Lenvatinib plus transarterial chemoembolization with or without immune checkpoint inhibitors for unresectable hepatocellular carcinoma: A review.

Lenvatinib plus transarterial chemoembolization (TACE)have become the first choice for patients with hepatocellular carcinoma (HCC) that are unsuitable for TACE. Sorafenib plus TACE therapy for patients with portal vein tumor thrombus (PVTT) achieved positive results. However, Lenvatinib plus TACE appeared to achieve a more advantageous result for these patients based on the phase 3 REFLECT trial. Both TACE and lenvatinib therapy have immune-stimulating effects, so would lenvatinib plus TACE and immune checkpoint inhibitors be an advantageous therapy for unresectable HCC (uHCC)? Thirteen articles from PubMed were explored to determine the efficacy and safety of lenvatinib plus TACE with or without PD-1 inhibitors therapy. Most of the adverse events (AEs) were manageable. Lenvatinib plus TACE therapy was superior to lenvatinib monotherapy with intermediate stage HCC especially beyond up-to-seven criterion and was superior to TACE monotherapy in patients with uHCC or sorafenib plus TACE therapy in patients with PVTT. Objective response rates (ORRs) of 53.1%–75%, median progression free survival (PFS) of 6.15–11.6 months, and median overall survival (OS) of 14.5–18.97 months were achieved in the lenvatinib plus TACE group. Levatinib plus TACE and PD-1 inhibitors achieved ORRs of 46.7% –80.6%, median PFS of 7.3–13.3 months, and median OS of 16.9–24 months. Control studies also confirmed the triple therapy was superior to lenvatinib plus TACE in patients with uHCC. Overall, the triple therapy is a promising treatment for patients with uHCC, including main PVTT and extrahepatic metastasis. Lenvatinib plus TACE therapy was also preferable for intermediate stage HCC beyond up-to-seven criterion and for patients with PVTT.

Efficacy of transarterial chemoembolization monotherapy or combination conversion therapy in unresectable hepatocellular carcinoma: A systematic review and meta-analysis.

BackgroundHepatocellular carcinoma (HCC) is a highly malignant disease with poor prognosis, and most cases were already considered unresectable at the time of presentation. Conversion therapy, as an emerging treatment, is designed to provide patients with initially unresectable hepatocellular carcinoma (uHCC) the opportunity to undergo radical resection. At present, conversion therapy for patients with uHCC remains controversial. Transarterial chemoembolization (TACE) is currently the most widely selected treatment for uHCC, but its efficacy as a conversion therapy remains controversial.MethodsWe compared and evaluated the conversion rate for and tumor response to TACE monotherapy or combination therapy. Meanwhile, postoperative complications and overall survival (OS) in uHCC patients who underwent conversion therapy were also analyzed.ResultsA total of 18 studies were included in this meta-analysis. The conversion rate for triple therapy [TACE in combination with tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibitors (ICIs)] was 42% [95% confidence interval (CI), 0.29–0.56], higher than any other group [TACE monotherapy: 10% (95% CI, 0.08–0.12), bigeminy therapy: 19% (95% CI, 0.06–0.36)]. Meanwhile, triple therapy yielded a better tumor response than TACE monotherapy or bigeminy therapy. Among the patients with successful surgical resection after conversion therapy, the pooled postoperative OS rates at 1, 2, and 5 years were 90% (95% CI, 0.81–0.97), 58% (95% CI, 0.42–0.73), and 42% (95% CI, 0.26–0.60), respectively, and the major postoperative complications were biliary leakage (7%; 95% CI, 0.03–0.12) and liver failure (3%; 95% CI, 0.00–0.07).ConclusionTACE conversion therapies showed good conversion rates, especially the triple therapy of TACE in combination with TKIs and ICIs. Surgical resection after successful conversion therapy could maximize the outcome of patients with uHCC.

Transarterial Chemoembolization Combined With Tyrosine Kinase Inhibitors for Intermediate-Stage Hepatocellular Carcinoma, What Else Can We Do?

Transarterial chemoembolization (TACE) has been considered the standard treatment for intermediate-stage hepatocellular carcinoma (HCC). However, intermediate‐stage HCC is highly heterogeneous with a broad population with varying tumour burdens, liver function. This suggests that TACE monotherapy treatment might not be suitable for all patients with intermediate‐stage HCC. The administration of tyrosine kinase inhibitors (TKIs) has become an important treatment option for improving the prognosis of patients with advanced HCC. Over the years, several trials have been conducted to explore the effects of TACE combined with TKIs for intermediate-stage HCC. However, the clinical efficacy is still controversial, and its potential clinical utility needs to be confirmed. This review will focus on the recent progress of TACE combined TKIs for intermediate-stage HCC.

Combined radiofrequency ablation or microwave ablation with transarterial chemoembolization can increase efficiency in intermediate-stage hepatocellular carcinoma without more complication: a systematic review and meta-analysis

Objectives Radiofrequency ablation (RFA) and microwave ablation (MWA) are widely used in combination with transarterial chemoembolization (TACE) for intermediate-stage hepatocellular carcinoma (HCC) in clinical practice. We aim to compare the efficacy and safety of TACE combined with RFA or MWA versus TACE monotherapy for intermediate-stage HCC. Methods We searched PubMed, Embase, Web of Science, and the Cochrane Library for relevant studies. The outcomes included overall survival (OS), progression-free survival (PFS), local tumor control (LTC) rate, and major complication. Subgroup analysis for different TACE combination therapies was performed. Results Ten studies with 1799 patients with intermediate-stage HCC were included. The pooled hazard ratio (HR) for OS was in favor of TACE combination therapy (HR, 0.50, 95% confidence interval [CI], 0.40–0.62). Specifically, the TACE combination therapy was associated with higher 1-, 3-, and 5-year OS rates. Regarding tumor progression, the TACE combination therapy showed significantly better PFS (HR, 0.47, 95% CI, 0.37–0.61) and higher 1-, 2- and 3-year PFS rates than TACE monotherapy. The pooled odds ratio (OR) for the LTC was also in favor of TACE combination therapy (OR, 0.36, 95% CI, 0.24–0.53). No significant difference was found between the two groups regarding the major complication rate (OR, 1.26, 95% CI, 0.74–2.16). These results were consistent across subgroups of TACE + RFA versus TACE and TACE + MWA versus TACE. Conclusion TACE combined with RFA or MWA can provide significantly better OS, PFS and LTC than TACE monotherapy for patients with intermediate-stage HCC, without increasing the risk of major complications.

Tumor feeding artery contraction and metastasis inhibition after transarterial chemoembolization combined with apatinib for hepatocellular carcinoma: A propensity score matching study.

To investigate the change of tumor feeding artery diameter and the efficacy of metastasis inhibition after transarterial chemoembolization (TACE) combined with apatinib or TACE monotherapy for patients with advanced hepatocellular carcinoma who without metastasis. A total of 616 consecutive patients who received the treatment of TACE-apatinib or TACE in our center was enrolled. Propensity score matching (PSM) analysis was used to reduce bias. The overall survival (OS), OS-after-metastasis (OSM), time to progression (TTP), time to metastasis (TTM), time to vessel or organ metastasis (TVOM), time to lymph node metastasis, and tumor feeding artery diameter between the two treatment groups were compared. A total of 113 pairs of patients were eligible after the PSM. Time to lymph node metastasis between the two groups was not significantly different (P>0.05). The tumor feeding artery diameter was significantly smaller after TACE-apatinib management (P<0.001). Median OS (P<0.001) and OSM (P<0.001) were significantly longer in the TACE-apatinib group compared with the TACE group. Median TTP (P<0.001), TTM (P<0.001), and TVOM (P<0.001) were significantly prolonged in TACE-apatinib group. TACE-apatinib treatment could improve the prognosis compared with TACE alone, and inhibit metastasis after TACE procedure with contracted tumor feeding artery for advanced HCCs without metastasis.

ABO Blood Group Differentials on Survival in Hepatocellular Carcinoma Patients Treated with Chemoembolization

Background:The association between ABO blood group and the prognosis of hepatocellular carcinoma (HCC) remains unclear. We investigated the impact of ABO blood groups as a prognostic factor in HCC patients treated with transarterial chemoembolization (TACE). Materials and methods:We revisited records of all HCC patients who underwent TACE between January 2007 and December 2019 at a tertiary care hospital. The inclusion criteria were HCC patients, Child-Pugh score A5-B7, and treated with TACE monotherapy. The baseline characteristics of each patient were compared against their blood group and the survival analysis was carried out using Cox’s regression. With Bonferroni adjustment for multiple comparisons, P-values <.0125 were considered statistically significant. Results:Of 211 eligible patients, the frequencies of blood groups O, A, B, and AB were 89, 54, 56, and 12, respectively. Their respective months of median survival were 41, 20, 21, and 42. After adjustments in the six-and-twelve criteria and Child-Pugh scores, and using blood group O as the referent group, the coefficients (SE) of groups A, B, and AB were 0.69 (0.24), 0.47 (0.23), and 0.49 (0.49), respectively. A significant difference in survival was found only between patients with blood group O vs A (hazard ratio, 2.00; confidence interval, 1.25-3.21). Conclusions:ABO blood group is associated with the prognosis of HCC patients treated with TACE monotherapy. In our data, patients with blood group O tended to have the best survival. However, only blood group A patients had a significantly shorter survival rate comparing to blood group O.

Hepatic Artery Infusion Chemotherapy Using Fluorouracil, Leucovorin, and Oxaliplatin versus Transarterial Chemoembolization as Initial Treatment for Locally Advanced Hepatocellular Carcinoma: A Propensity Score–Matching Analysis

PurposeTo compare the efficacy and safety of hepatic arterial infusion chemotherapy (HAIC) with a modified fluorouracil, leucovorin, and oxaliplatin (mFOLFOX) regimen with that of transarterial chemoembolization as a locoregional treatment for patients with locally advanced hepatocellular carcinoma (HCC). MethodsThis retrospective study included adult patients with locally advanced HCC who received first-line treatment with either HAIC-mFOLFOX or conventional transarterial chemoembolization monotherapy from January 2015 to December 2016. The outcomes, including tumor response rates, evaluated via imaging assessment using the modified response evaluation criteria in solid tumors; overall survival; progression-free survival; and safety, were compared. The propensity score–matching methodology was used to reduce the influence of confounding factors on the outcomes. ResultsThe study included 131 patients with locally advanced HCC who underwent transarterial chemoembolization and 101 who received HAIC-mFOLFOX as initial treatment. After propensity score matching (n = 67 in each group), patients who received HAIC-mFOLFOX had a higher objective response rate (43.3% vs 13.4%, P = .001), longer median overall survival (13.9 vs 6.0 months, P < .001), and longer median progression-free survival (6.4 vs 2.8 months, P = .001) than those who underwent transarterial chemoembolization. The survival benefit with HAIC-mFOLFOX was strengthened in patients with HCC with vascular invasion (hazard ratio: 0.379; 95% confidence interval: 0.237–0.607). HAIC-mFOLFOX was associated with lower incidences of severe adverse events (8.9% vs 22.9%) and liver toxicity than transarterial chemoembolization. ConclusionsCompared with transarterial chemoembolization, HAIC-mFOLFOX is a potentially safer and more effective locoregional therapy for patients with locally advanced HCC.

Lenvatinib in combination with transarterial chemoembolization for treatment of unresectable hepatocellular carcinoma (uHCC): a retrospective controlled study

PurposeTo compare the efficacy and safety of combined treatment with lenvatinib and transarterial chemoembolization (TACE) versus TACE only in patients with unresectable hepatocellular carcinoma (uHCC).MethodsOf the 120 patients enrolled in this study, 60 patients received treatment with TACE only, and 60 patients received TACE plus lenvatinib. We retrospectively compared the clinical outcomes including overall survival (OS), progression-free survival (PFS), and tumor response between the two groups. Both PFS and tumor response were based on the modified Response Evaluation Criteria in Solid Tumors (mRECIST). Adverse events were analyzed to assess the safety profiles.ResultsThe 1-year and 2-year OS rates were significantly higher in the TACE + lenvatinib group (88.4% and 79.8%) than that in the TACE group (79.2% and 49.2%, p = 0.047). A similar PFS benefit was observed in the TACE + lenvatinib group (1-y PFS rate: 78.4% vs. 64.7%, 2-y PFS rate: 45.5% vs. 38.0%, p < 0.001). The best overall objective response rate (ORR) was also better with TACE + lenvatinib treatment (ORR: 68.3% vs. 31.7%, p < 0.001) and disease control rate (DCR) numerically increased in the TACE + lenvatinib treatment (93.3% vs. 86.7%, p = 0.224). Patients’ liver function remained comparable to baseline in the TACE + lenvatinib group. The most common adverse events were decreased albumin (55.0%), hypertension (48.3%) and decreased platelet count (46.7%) in the TACE + lenvatinib group.ConclusionsCombination treatment with TACE and lenvatinib may significantly improve clinical outcomes over TACE monotherapy with a manageable safety profile for unresectable HCC. The efficacy of the combination treatment should be validated in prospective studies with a large sample size.Graphical abstract
