Assessment of efficacy and safety of the transcatheter arterial chemoembolization with or without apatinib in the treatment of large hepatocellular carcinoma

Association of serum AFP trajectories and hepatocellular carcinoma outcomes after hepatic arterial infusion chemotherapy: A longitudinal, multicenter study

AIM

This study aims to investigate α-fetoprotein (AFP) trajectories for prediction of survival outcomes after hepatic arterial infusion chemotherapy (HAIC) treatment in large hepatocellular carcinoma (HCC).

METHODS

From May 2014 to June 2020, 889 eligible patients with large HCC underwent HAIC were retrospectively enrolled from five hospitals. A latent class growth mixed (LCGM) model was applied to distinguish potential AFP level dynamic changing trajectories. Inverse-probability-of-treatment weighted (IPTW) analyses were performed to eliminate unmeasured confounders through marginal structural models. Multivariate Cox proportional hazard regression analyses were used to determine the overall survival (OS) in patients with large HCC. Performance of these serum markers for survival prediction was compared by areas under receiver operating characteristic analysis with the Delong test.

RESULTS

The median follow-up time was 23.7 (interquartile range, 3.8-115.3). A total of 1009 patients with large HCC, who underwent HAIC with AFP repeatedly measured 3-10 times, were enrolled in the study. Three distinct trajectories of these serum AFP were identified using the LCGM model: high stable (37.0%; n = 373), low stable (15.7%; n = 159), and sharp-falling (47.3%; n = 477). Multivariate Cox proportional hazard regression analyses found that ALBI stage 2-3, BCLC-C stage and high-stable AFP trajectories were associated with OS. AFP trajectories yield the optimal predictive performance in all risk factors.

CONCLUSIONS

The AFP trajectories based on longitudinal AFP change showed outstanding performance for predicting survival outcomes after HAIC treatment in large HCC, which provide a potential monitoring tool for improving clinical decision-making.

Comparative efficacy and safety of molecular targeted agents combined with transarterial chemoembolization in the treatment of unresectable hepatocellular carcinoma: a network meta-analysis

Objective

At present, several molecular targeted agents(MTAs) combined with transarterial chemoembolization (TACE) have been employed to treat unresectable hepatocellular carcinoma (HCC). In this meta-analysis, we compared the efficacy and safety of different MTAs combined with TACE to enable effective decision-making for the clinical treatment of unresectable HCC.

Methods

Pubmed, Web of Science, EMBASE, and Cochrane Library were retrieved to evaluate the efficacy and safety of different MTAs combined with TACE in cohort studies and randomized controlled trials. The hazard ratios and 95% confidence intervals (CIs) were calculated to investigate the impact of various therapies on overall survival (OS) and progression-free survival. However, the objective response rate (ORR), disease control rate (DCR), adverse events (AEs), and ≥grade-3 adverse events (≥G3-AEs) were calculated using odd ratios and 95% CIs. The node-splitting approach was used to test the heterogeneity. The funnel plot was utilized to analyze the publication bias. Additionally, according to the ranking plots, we ranked various treatments.

Results

A total of 45 studies involving 10,774 patients with 8 treatment strategies were included in our network meta-analysis. Our network meta-analysis showed that apatinib+TACE provided the highest OS (62.2%), ORR (44.7%), and DCR (45.6%), while and lenvatinib+TACE offered the best PFS (78.9%). Besides, there was no statistically significant difference in AEs and ≥G3-AEs among treatment options.

Conclusion

Apatinib+TACE demonstrated the best OS, ORR, and DCR with no additional AEs and ≥G3-AEs. Therefore, for the treatment scheme of MTAs combined with TACE, apatinib+TACE may be the best option for patients with unresectable HCC.

Transarterial chemoembolization (TACE) plus tyrosine kinase inhibitors versus TACE in patients with hepatocellular carcinoma: a systematic review and meta-analysis

PURPOSE

Transarterial chemoembolization (TACE) with tyrosine kinase inhibitors (TKIs) has been increasingly used to treat unresectable hepatocellular carcinoma (uHCC). However, the superiority of combination therapy to TACE monotherapy remains controversial. Therefore, here we performed a meta-analysis to evaluate the efficacy and safety of TACE plus TKIs in patients with uHCC.

METHODS

We searched four databases for eligible studies. The primary outcome was time to progression (TTP), while the secondary outcomes were overall survival (OS), tumor response rates, and adverse events (AEs). Pooled hazard ratios (HRs) with 95% confidence intervals (95% CIs) were collected for TTP and OS, and the data were analyzed using random-effects meta-analysis models in STATA software. OR and 95% CIs were used to estimate dichotomous variables (complete remission[CR], partial remission[PR], stable disease[SD], progressive disease[PD], objective response rate[ORR], disease control rate[DCR], and AEs) using RStudio's random-effects model. Quality assessments were performed using the Newcastle-Ottawa scale (NOS) for observational studies and the Cochrane risk of bias tool for randomized controlled trials (RCTs).

RESULTS

The meta-analysis included 30 studies (9 RCTs, 21 observational studies) with 8246 patients. We judged the risk of bias as low in 44.4% (4/9) of the RCTs and high in 55.6% (5/9) of the RCTs. All observational studies were considered of high quality, with a NOS score of at least 6. Compared with TACE alone or TACE plus placebo, TACE combined with TKIs was superior in prolonging TTP (combined HR 0.72, 95% CI 0.65-0.80), OS (combined HR 0.57, 95% CI 0.49-0.67), and objective response rate (OR 2.13, 95% CI 1.23-3.67) in patients with uHCC. However, TACE plus TKIs caused a higher incidence of AEs, especially hand-foot skin reactions (OR 87.17%, 95%CI 42.88-177.23), diarrhea (OR 18.13%, 95%CI 9.32-35.27), and hypertension (OR 12.24%, 95%CI 5.89-25.42).

CONCLUSIONS

Our meta-analysis found that TACE plus TKIs may be beneficial for patients with uHCC in terms of TTP, OS, and tumor response rates. However, combination therapy is also associated with a significantly increased risk of adverse reactions. Therefore, we must evaluate the clinical benefits and risks of combination therapy. Further well-designed RCTs are needed to confirm our findings.

Efficacy of Transarterial Chemoembolization Combined with Molecular Targeted Agents for Unresectable Hepatocellular Carcinoma: A Network Meta-Analysis

Simple Summary

Liver cancer is the second most common cause of cancer-related death, with hepatocellular carcinoma (HCC) being the most prevalent subtype. Transarterial chemoembolization (TACE) in combination with different tyrosine kinase inhibitors (TKIs) has recently been widely used for unresectable HCC (uHCC). However, studies investigating different combinations of agents have shown inconsistent results. Thus, we conducted a network meta-analysis to assess and compare the response of different agents in an uHCC setting. According to our results, TACE plus lenvatinib provides optimal treatment for uHCC, with the highest ranking based on OS, PFS, and DCR rates and the second-best ranking based on ORR rates.

Abstract

Transarterial chemoembolization (TACE) combined with tyrosine kinase inhibitors (TKIs) is the mainstay treatment for unresectable hepatocellular carcinoma (uHCC). However, studies investigating different combinations of agents have shown inconsistent results. Here, we used network meta-analysis (NMA) to compare different agents across 41 studies (36 cohort studies and five RCTs) in 11,540 patients. Multiple RCTs and cohort studies were searched to evaluate TACE combined with different TKIs. Outcomes of interest included overall survival (OS), progression-free survival (PFS), and tumor response. NMA used a random-effects consistency model to pool evidence from direct and indirect comparisons. Hazard ratio (HR) and relative risks (RR) with 95% confidence intervals (CI) were analyzed. Further, heterogeneity and publication bias analyses were performed and agents were ranked. TACE plus lenvatinib provided the maximal OS (Rank probability: 0.7559), PFS (Rank probability: 0.8595), CR (Rank probability: 0.4179), and DCR (Rank probability: 0.3857). TACE plus anlotinib demonstrated the highest PR (p = 0.62649) and ORR (p = 0.51158). SD was more often associated with TACE plus sorafenib (Rank probability: 0.601685). TACE plus lenvatinib provides optimal treatment for uHCC based on the highest ranking of OS, PFS, and DCR rates. However, given the lack of statistically significant OS benefit, shared decision making should include other TKIs as acceptable alternatives.

The efficacy and safety of Apatinib combined with TACE in the treatment of hepatocellular carcinoma: a meta-analysis

Background

The timely and effective treatments are vital to the prognosis of patients with hepatocellular carcinoma, and the role of Apatinib combined with TACE in the treatment of hepatocellular carcinoma remains unclear. Therefore, we aimed to conduct a systematic review and meta-analysis to evaluate the efficacy and safety of Apatinib combined with transcatheter arterial chemoembolization (TACE) in the treatment of hepatocellular carcinoma.

Methods

We searched for randomized controlled trials (RCTs) on Apatinib and TACE use in the treatment of hepatocellular carcinoma. Cochrane Central Register of Controlled Trials, Embase, PubMed, China Biomedical Literature Database, China Knowledge Network, Wanfang Database, and Weipu Chinese Science and Technology Journal Database were searched up to 16 April 2021. Two researchers independently screened the literature and extracted data according to the inclusion and exclusion criteria. RevMan 5.3 software was used for Meta-analysis. This meta-analysis protocol had been registered online (available at: https://inplasy.com/inplasy-2021-6-0047/).

Results

A total of 14 RCTs involving 936 hepatocellular carcinoma patients were included. The objective remission rate (OR = 2.93, 95% CI 2.17–3.95), 1-year survival (OR = 2.47, 95% CI 1.65–3.68), 2-year survival (OR = 2.67, 95% CI 1.41–5.04), the incidence of hand-foot syndrome (OR = 32.09, 95% CI 10.87–94.74) and the incidence of proteinuria (OR = 14.79, 95% CI 6.07–36.06) of the Apatinib + TACE group was significantly higher than that of the TACE group (all P < 0.05). There were no significant differences in the incidence of myelosuppression (OR = 1.01, 95% CI 0.61–1.67), the incidence of hypertension (OR = 7.56, 95% CI 0.95–1.67, P = 60.17) between Apatinib + TACE and TACE group (all P > 0.05).

Conclusions

Apatinib combined with TACE is more effective than TACE alone in the treatment of hepatocellular carcinoma, but it has certain adverse reactions.

Efficacy and safety of drug-eluting bead transarterial chemoembolization (DEB-TACE) plus apatinib versus DEB-TACE alone in treating huge hepatocellular carcinoma patients

Background

Apatinib, a tyrosine kinase inhibitor, inhibits angiogenesis under the tumor hypoxic environment induced by drug-eluting bead transarterial chemoembolization (DEB-TACE), which is hypothesized to have synergic effect with DEB-TACE in treating hepatocellular carcinoma (HCC) patients. This study aimed to evaluate the efficacy and safety of DEB-TACE plus apatinib in treating huge HCC patients.

Methods

Totally, 73 huge HCC patients (tumor size > 10 cm) were screened and divided into DEB-TACE plus apatinib group (N = 34) or DEB-TACE group (N = 39) based on the treatment they received. Their clinical response and adverse events were retrieved. The progression-free survival (PFS) and overall survival (OS) were calculated.

Results

DEB-TACE plus apatinib achieved a trend of higher objective response rate (64.7% vs. 43.6%, P = 0.071), but similar disease control rate (88.2% vs. 79.5%, P = 0.314) than DEB-TACE alone. Moreover, DEB-TACE plus apatinib reached an improved PFS (median (95%CI): 19.0 months (15.5–22.5) vs. 10.9 months (8.0–13.8), P = 0.025) and OS (median (95%CI): 25.1 months (20.3–29.9) vs. 13.7 months (9.8–17.6), P = 0.042) than DEB-TACE alone. After adjustment by multivariate Cox’s regression analyses, DEB-TACE plus apatinib (vs. DEB-TACE alone) was independently correlated with better PFS (HR: 0.420, P = 0.004) and OS (HR: 0.477, P = 0.022). Regarding safety, adverse events were mostly mild and manageable; also, they were of no difference between DEB-TACE plus apatinib and DEB-TACE alone (all P > 0.05).

Conclusion

DEB-TACE plus apatinib achieves prolonged PFS and OS, while similar adverse events occurrence compared to DEB-TACE alone in huge HCC treatment.

Comprehensive Treatment of Trans-Arterial Chemoembolization Plus Lenvatinib Followed by Camrelizumab for Advanced Hepatocellular Carcinoma Patients

Aim: This study aimed to report the efficacy and safety of trans-arterial chemoembolization (TACE) plus lenvatinib and camrelizumab in patients with advanced hepatocellular carcinoma (HCC). Methods: This retrospective study enrolled 22 patients with advanced HCC from March 2018 to December 2019. All the patients received comprehensive treatment with TACE plus lenvatinib followed by camrelizumab. Overall survival (OS) and progression-free survival (PFS) were calculated and analysed using the Kaplan-Meier method and log-rank test. Treatment response and adverse events (AEs) were also evaluated. Results: The objective response rate (ORR) and disease control rate (DCR) for the whole cohort were 68.2 and 100% at the first month and 72.7 and 95.5% at the third month, respectively. The median OS was 24 months (95% CI, 20.323-27.677 months), and the median PFS was 11.4 months (95% CI, 8.846-13.954 months). The majority of treatment-related adverse reactions were mild or moderate, except for 4 that developed to grade 3-4 (3 reactions of grade 3, 1 reaction of grade 4). No deaths or other serious adverse reactions occurred. Conclusion: Trans-arterial chemoembolization plus lenvatinib and camrelizumab shows good results incontrolling tumour progression and prolonging median OS in patients with advanced HCC.

Efficacy and Safety of the Arsenic Trioxide/Lipiodol Emulsion in the Transcatheter Arterial Chemoembolization Combined with Apatinib in the Treatment of Advanced Hepatocellular Carcinoma

PURPOSE

The goal of this study was to assess the clinical efficacy and safety of the arsenic trioxide (ATO)/lipiodol emulsion in the transcatheter arterial chemoembolization (TACE) combined with apatinib in the treatment of advanced hepatocellular carcinoma (HCC).

METHODS

From December 2015 to February 2017, a total of 87 patients were consecutively enrolled and underwent ATO-TACE (aTACE) combined with apatinib in the treatment of advanced HCC. The treatment response and adverse events were assessed at the first month and third month after aTACE therapy. Progression-free survival (PFS), overall survival (OS), and treatment-related adverse events were also analyzed.

RESULTS

87 patients (57 men; 30 women) were enrolled in the present study. Compared to that at the pre-aTACE examination, the levels of AST and ALT were elevated at the first week after procedure (65.84 U/L ± 22.93 U/L vs. 54.15 U/L ± 19.60 U/L, p=0.032; 63.44 U/L ± 22.50 U/L vs. 51.60 U/L ± 13.89 U/L, p=0.027, respectively). Most of the adverse events were grade 1 or 2 according to National Cancer Institute Common Terminology Criteria for Adverse Event (CTCAE). Of the exception, 4 persons (2%) did have grade 3 hand-foot skin reactions, 1 (1%) had grade 3 diarrhea, 1 (1%) had grade 3 hypertension, and 3 (3%) had grade 3 proteinuria and forced to reduce the dose of apatinib by half. The survival analysis of the combination with aTACE and apatinib therapy found that the median PFS was 10.2 months (95% CI: 8.543-11.857), and the median OS was 23.300 months (95% CI: 20.833-25.767). Additionally, both univariate and multivariate Cox regression revealed that the tumor burden (≤50%) and the patients without portal vein tumor thrombus (PVTT) significantly impacted the patient's PFS and OS and were related to better survival.

CONCLUSION

aTACE combined with apatinib is a safe and promising treatment approach for patients with advanced HCC. Additionally, tumor burden (≤50%) and the patients without PVTT are associated with better PFS and OS.

Apatinib-loaded CalliSpheres Beads for embolization in a rabbit VX2 liver tumor: characterization in vitro, pharmacokinetics and tumor response in vivo

Apatinib mesylate is an oral antiangiogenic agent that can inhibit activation of vascular endothelial growth factor receptor-2 tyrosine kinase. However, its therapeutic use in liver cancer is restricted due to severe systemic toxicity. Our work aimed to construct apatinib-loaded CalliSpheres Beads (CBAPA) and investigate its application in transarterial chemoembolization (TACE) of liver cancer. The established stock solution containing 20, 40 or 60 mg apatinib were fully mixed with 100-300 μm CalliSpheres Beads (CB) for 2 hours, respectively. The highest loading efficiency at 30 min after combination in 20 mg group (maximum 70.7%). Further, apatinib can be steadily released from CBAPA in vitro release test. For pharmacokinetics and tumor response in vivo, sixty New Zealand white rabbits with VX2 liver tumor were assigned into four groups: sham (NS) group, apatinib solution alone (APA) group, CB group and CBAPA group. Apatinib was measured in plasma and liver tissue by high performance liquid chromatography-tandem mass spectrometry. Compared to APA group, the administration of apatinib by TACE with CBAPA resulted in low systemic concentration. In addition, intratumoural apatinib concentration was higher than adjacent hepatic parenchyma in the CBAPA group. Compared to other three groups, CBAPA group achieved lower tumor growth rate and improved survival time. In conclusion, these findings provide a basis for the potential application of apatinib-loaded CalliSpheres Beads in liver cancer.

Sec62 promotes pro-angiogenesis of hepatocellular carcinoma cells under hypoxia

This study aimed to investigate the underlying molecular pathogenic mechanism of Sec62 in hepatocellular carcinoma (HCC). Microarray analysis was conducted to profile the global gene expression in the HCC cell line Huh7 cells transfected with Sec62^high vs. NC and Sec62^low vs. NC. Ingenuity pathway analysis and gene set enrichment analysis were used to perform Sec62-related signaling pathway analysis from screened differentially expressed genes (DEGs). A protein-protein interaction network was constructed. Experimental validation of the expression of key DEGs was conducted. Hypoxia-induced tube formation was undertaken to investigate the role of Sec62 in angiogenesis. A total of 74 intersected DEGs were identified from Huh7 cells with Sec62^high vs. NC and Sec62^low vs. NC. Among them, 65 DEGs were correlated with the expression of Sec62. The P53 signaling pathway was found to be enriched in Huh7 cells with Sec62^high vs. NC, while the acute phase response signaling pathway was enriched in Huh7 cells with Sec62^low vs. NC. DEGs, such as serine protease inhibitor E (SERPINE) and tumor necrosis factor receptor superfamily, member 11B (TNFRSF11B), were not only identified as the lead genes of these enriched pathways, but were also found to be closely related to Sec62. Moreover, knockdown of Sec62 decreased the expression of SERPINE1 (plasminogen activator inhibitor type 1 (PAI-1)) and TNFRSF11B, whereas overexpression of Sec62 had the opposite effects. In addition, knockdown of Sec62 inhibited hypoxia-induced tube formation via PAI-1. Sec62 promoted pro-angiogenesis of HCC under hypoxia by regulating PAI-1, and it may be a crucial angiogenic switch in HCC.
