Background: The combination of local therapy with lenvatinib and programmed cell death protein-1 (PD-1) inhibitors represents an emerging treatment paradigm for unresectable hepatocellular carcinoma (uHCC). Our study sought to investigate the interrelationship between gut microbiota and intratumoral microbiota in the context of triple therapy, with a view to identifying potential biological markers. Methods: The gut microbial community profiles of patients with primary untreated hepatocellular carcinoma (HCC) and those treated with local therapy combined with lenvatinib and PD-1 inhibitors were analyzed by 16S rRNA gene amplicon sequencing. Additionally, microbial community profiles of tumor tissues of patients with HCC and normal liver tissues were analyzed. Results: In our investigation, we observed that patients with HCC who received triple therapy exhibited a notable enhancement in the abundance of Actinobacteriota and a considerable decrease in Escherichia Shigella. Patients who received hepatic artery infusion chemotherapy (HAIC) in combination with levatinib and PD-1 inhibitors exhibited significantly elevated levels of Faecalibacterium prausnitzii and Bacteroides stercoris in comparison to those who received transarterial chemoembolization (TACE) in combination with levatinib and PD-1 inhibitors. Furthermore, a notable decline in microbial diversity was observed within HCC tumors in comparison to normal liver tissues. The gut and intratumoral microbiota in HCC patients exhibited a high degree of similarity to the microbes present at the phylum level. Conclusions: Gut microbiota is connected to triple therapy with local therapy combined with lenvatinib and PD-1 inhibitors for HCC. These discoveries underscore the potential of utilizing gut microbiota and intratumoral microbiota as biomarkers, as well as the possibility of triple therapy in the management of HCC.

Purpose: To assess the activity and toxicity of hepatic arterial infusion chemotherapy (HAIC)+tislelizumab+lenvatinib (HAIC+tisle+len) in hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT) type IV (Vp4 hCC) in a real-world context. Methods: Fifty-five patients, with Vp4 hCC receiving HAIC+tisle+len therapy from April 2021 to December 2022, were analyzed retrospectively. Data on patient characteristics, adverse events (AEs), treatment, and survival were collected. Outcomes were disease control rate (DCR), overall response rate (ORR), overall survival (OS), progression-free survival (PFS), and treatment-related AEs (TRAEs). Results: As of December 20, 2023, the median follow-up was 17.5 months (95% confidence interval [CI]: 14.7– 22.5). The ORR was 52.7% (3 complete response [CR], 26 partial response [PR]) as per RECIST v1.1 and 65.5% (12 CR, 24 PR) as per mRECIST. The DCR was 94.5% using both RECIST v1.1 and mRECIST. The median PFS and the median OS were 8.0 months (95% CI: 6.2– 12.3) and 16.7 months (95% CI: 12.0-not reached), respectively. Additionally, PFS was independently predicted only by the best tumor response. In patients with the best tumor response (PR or CR), the median PFS was 11.7 months (95% CI: 8.02-not reached) by mRECIST and 15.4 months (95% CI: 7.39-not reached) by RECIST v1.1. Hypertension (14.5%), decreased albumin levels (10.9%) and anorexia (9.1%) were the most frequently observed grade 3– 4 TRAEs. Conclusion: HAIC+tisle+len regimen demonstrated a promising efficacy and favorable safety for patients with HCC and Vp4, providing valuable real-world evidence to complement the trial data for Vp4 hCC.

Background: Tumor lysis syndrome is a life-threatening complication in the treatment of cancer. However, it rarely occurs in solid tumors, especially in hepatocellular carcinoma. Case presentation: We present a 52-year-old male Asian patient with advanced hepatocellular carcinoma treated with hepatic artery infusion chemotherapy that resulted in tumor lysis syndrome. The patient developed symptoms of oliguria, seizure, hyperkalemia, hyperuricemia, hypocalcemia, hyperphosphatemia, and increased creatinine. He recovered from it after adequate hydration, correction of metabolic abnormalities, and renal replacement therapy. Conclusions: This case highlights the importance of maintaining a high index of suspicion of TLS even in solid tumors such as hepatocellular carcinoma, especially with a large tumor burden. It also underscores the need for early intervention in suspected TLS for a successful outcome. [ABSTRACT FROM AUTHOR]

Prognostic factors for progression-free survival (PFS) and overall survival (OS) were identified using univariate and multivariate Cox regression analyses. The discriminatory capability of inflammation-based prognostic scores—including the CRP/Alb ratio, C-reactive protein and alpha-fetoprotein in immunotherapy (CRAFITY) score, modified Glasgow prognostic score (mGPS), platelet-lymphocyte ratio (PLR), and systemic immune-inflammation index (SII)—was assessed using the area under the curve (AUC).Results: A total of 133 patients met the inclusion criteria. The optimal cutoff value for the binary classification of CRP/Alb ratio in predicting OS, as determined using X-tile software, was 0.02. Multivariate analysis identified the CRP/Alb ratio (hazard ratio [HR] = 2.61, p < 0.001), tumor size (HR = 2.45, p = 0.018), and extrahepatic metastases (HR = 1.93, p = 0.015) as independent predictors of OS. For PFS, significant factors included Eastern Cooperative Oncology Group Performance Status (HR = 1.55, p = 0.033) and macrovascular invasion (HR = 1.48, p = 0.046). Patients with higher CRP/Alb ratios were more likely to experience fever and fatigue. The CRP/Alb ratio demonstrated significantly higher AUCs than PLR and SII at 24 months (all p < 0.05) and showed comparable AUCs to CRAFITY score and mGPS at 12, 24, and 36 months.Conclusion: The CRP/Alb ratio is a valuable prognostic marker for predicting OS and treatment-related adverse events in HCC patients receiving transcatheter intra-arterial therapy combined with MTAs and PD-1/PD-L1 inhibitors. This ratio can be used as a simple and reliable biomarker for assessing prognosis and guiding patient selection in clinical practice.Keywords: transarterial chemoembolization, hepatic artery infusion chemotherapy, targeted therapy, immunotherapy, inflammation, C-reactive protein

Purpose: This retrospective study was conducted to evaluate the effectiveness and safety of a new combination therapy of radiotherapy (RT), hepatic arterial infusion chemotherapy (HAIC), tyrosine kinase inhibitors (TKI) and immune checkpoint inhibitors (ICI) for hepatocellular carcinoma (HCC) patients involving portal vein tumor thrombus (PVTT). Methods: A total of 71 HCC patients with PVTT were retrospectively analyzed: 45 patients were treated by 'HAIC + TKI + ICI' therapy and 26 patients by the new combination therapy. The primary outcomes were overall survival (OS), progression-free survival (PFS), and cumulative survival rate. Results: The PFS in the 'New combination therapy' group was longer than that in the 'HAIC + TKI + ICI' group (HR 0.459, 95%CI 0.253–0.832; P = 0.008). Meanwhile, the OS in the 'New combination therapy' group was also longer than that in the 'HAIC + TKI + ICI' group (HR 0.420, 95%CI 0.198–0.894; P = 0.024). Compared with 'HAIC + TKI + ICI' group patients, the 'New combination therapy' group patients had higher 1-year PFS rate and 1-year OS rate (P = 0.029; P = 0.015). There was no significant difference in the incidence of adverse events between the two groups. Conclusion: The new combination therapy was an effective and safe non-surgical treatment for HCC patients with PVTT and could be considered a preferred therapy option.

Background: Systemic and locoregional combination therapy has demonstrated promising outcomes for unresectable hepatocellular carcinoma (HCC); However, the best combination option remains unknown. This study compared the efficacy and safety of lenvatinib and tislelizumab versus atezolizumab and bevacizumab in combination with transarterial embolization (TAE) plus hepatic artery infusion chemotherapy (HAIC) for unresectable HCC with high tumor burden. Methods: This multicenter retrospective cohort study enrolled treatment-naive patients with unresectable HCC treated with TAE-HAIC plus lenvatinib and tislelizumab (THLP group) or TAE-HAIC plus atezolizumab and bevacizumab (THTA group). The primary endpoint was overall survival (OS). Secondary endpoints included progression-free survival (PFS), tumor response, and adverse events (AEs). Propensity score matching (PSM) was performed to reduce bias. Results: Of the 240 patients enrolled, 153 and 51 patients were assigned to the THLP and THTA groups, respectively after PSM (3:1). The THLP group showed a longer median OS (22 months vs. 18.2 months; P = 0.412), whereas the median PFS was longer in the THTA group (8.1 months vs. 7 months; P = 0.723), with statistically insignificant intergroup differences. No statistical differences were observed in objective response rate (RECIST 1.1: 33.9 vs. 31.4%; mRECIST: 77.1% vs. 74.5%; P = 0.635), disease control rate (RECIST 1.1: 88.9% vs. 92.2; mRECIST: 92.2% vs. 94.1%; P = 0.716), and in grade 3/4 AEs. Gastrointestinal hemorrhage rate was significantly higher in the THTA group (9.1% vs. 1.6%; P = 0.007). All AEs were controllable and no treatment-related grade 5 AEs occurred. Conclusions: TAE-HAIC plus lenvatinib and tislelizumab or TAE-HAIC plus atezolizumab and bevacizumab showed similar outcomes for unresectable HCC with high tumor burden, and manageable safety. The results need further validation. [ABSTRACT FROM AUTHOR]

Propensity score matching(PSM) was utilized to adjust for baseline differences between groups. Survival outcomes and tumor response rate were used to assess survival benefits, while the incidence of adverse events was used to evaluate safety.Results: After screening for eligibility, 489 patients diagnosed with HCC and concomitant MVI were enrolled. Of these, 173 patients received treatment combining HAIC with PD-1 inhibitors, while 316 patients underwent HAIC monotherapy. After PSM adjustment, the combination therapy group demonstrate superior survival outcomes. Median overall survival(OS) and progression free survival(PFS) were 31.8 months and 10.8 months, respectively, significantly higher than those in the monotherapy group (OS: 10.0 months; PFS: 6.1 months; both P< 0.0001). Moreover, ORR and DCR remained significantly elevated in the combination therapy group (ORR: 44.3% vs 20.4%, P< 0.0001; DCR: 89.8% vs 82.0%, P=0.041). Safety profiles indicated no significant differences in adverse event rates between the two treatment groups, encompassing both overall and grade-specific assessments.Conclusion: Compared to HAIC alone, the combination of HAIC with PD-1 inhibitors represents a more promising and effective approach for patients with HCC complicated by macrovascular invasion.Keywords: hepatocellular carcinoma, programmed cell death protein 1, hepatic artery infusion chemotherapy, macrovascular invasion, propensity score matching

Abstract Background Tri-combination therapy based on hepatic arterial infusion chemotherapy (HAIC) of infusion fluorouracil, leucovorin, and oxaliplatin (FOLFOX-HAIC) plus immune checkpoint inhibitors (ICIs) and tyrosine kinase inhibitors (TKIs) for the locally advanced hepatocellular carcinoma (HCC) patients have been proven effective. However, whether it was best for these HCC patients to start with the most potent therapeutic pattern was still under debate. This retrospective study evaluated the efficacy and safety of FOLFOX-HAIC combined with systemic therapies in the patterns of sequential and concurrent schedules. Methods This real-world study included 117 unresectable HCC patients who initially received either FOLFOX-HAIC monotherapy (HAIC group, n = 44) or concurrent ICIs and TKIs (ConHAIC group, n = 73) from March 2020 and June 2022, during the period of FOLFOX-HAIC monotherapy in HAIC group, patients in the HAIC group (n = 30) experienced progressive disease (PD) would have their treatment pattern converted from the FOLFOX-HAIC monotherapy to the combination of FOLFOX-HAIC plus ICIs and TKIs sequentially (SeqHAIC group). The progression-free survival (PFS) and overall survival (OS), as primary outcomes, were compared between patients in the SeqHAIC and ConHAIC groups. Results The median follow-up time of the SeqHAIC group was 24.92 months (95% CI, 12.74–37.09 months) and of the ConHAIC group was 17.87 months (95% CI, 16.85–18.89 months) and no significant difference was observed in both PFS (HR, 1.572; 95% CI, 0.848–2.916; p = 0.151) and OS (HR, 1.212; 95% CI, 0.574–2.561; p = 0.614) between the SeqHAIC and the ConHAIC groups. As for the tumor responses, there was no significant difference between the two groups regarding tumor responses, overall response rates (p = 0.658) and disease control rates (p = 0.641) were 50.0%, 45.2%, and 83.3%, 89.0% for the SeqHAIC and the ConHAIC groups, respectively. Conclusion Our study revealed that sequential systemic ICIs and TKIs in combination with FOLFOX-HAIC provides similar long-term prognosis and better tolerability compared to concurrent therapy for locally advanced HCC patients. Prospective studies with a larger sample size and longer follow-up are required to validate these findings.

Purpose: Atezolizumab/bevacizumab (atezo-bev) is the first-line chemotherapy for patients with unresectable hepatocellular carcinoma (HCC). However, hepatic artery infusion chemotherapy (HAIC) can be used as an alternative. Our aim was to compare the prognosis of HAIC treatment between newly diagnosed patients and patients treated after failure of atezo-bev. Methods: We retrospectively assessed 73 patients with HCC treated with HAIC between January 2022 and September 2023. Fifty-seven patients were treated with HAIC at initial diagnosis, while 16 were treated with HAIC after first-line atezo-bev combination chemotherapy. We evaluated tumor responses, such as overall survival (OS), progression-free survival (PFS), and objective response rate (ORR). Results: No significant difference was observed in either OS or PFS between patients with HCC treated with HAIC at the initial diagnosis and those treated after atezo-bev treatment failure. However, the ORR of the initial HAIC group was 19.6% and that of the HAIC group after atezo-bev therapy failure was 43.6%, which was a statistically significantly difference. Conclusion: Although no significant difference was observed for OS and PFS, the ORR of patients in the HAIC group after the failure of atezo-bev therapy was superior to that of newly diagnosed patients. HAIC may prolong survival in patients with HCC after atezo-bev treatment failure. [ABSTRACT FROM AUTHOR]

Background: The triple combination of programmed cell death protein-1 (PD-1) inhibitors plus anti-angiogenesis tyrosine kinase inhibitors (TKIs) with or without transarterial chemoembolization (TACE) or hepatic arterial infusion chemotherapy (HAIC) enhance the effect of treatment for unresectable hepatocellular carcinoma (uHCC). The present study compared the efficacy and safety of PD-1 plus TKI with or without transarterial chemo(embolization) for uHCC. Methods: The meta-analysis was conducted using data acquired from PubMed, EMBASE, the Cochrane Library, Ovid, Web of Science, and Clinical Trials.gov from the inception date to December 2023. All clinical outcomes of interest included overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and adverse events (AEs). The hazard ratio (HR) and risk ratio (RR) with 95% confidence intervals (CIs) were used to measure the pooled effect. In addition, subgroup analysis was conducted to determine the specific patient population that benefited. Results: The OS (HR = 0.47; 95% CI: 0.39-0.56, P < 0.05), PFS (HR = 0.52; 95% CI: 0.45-0.60, P<0.05), and ORR (RR = 1.94; 95% CI: 1.60-2.35, P < 0.05) were significantly better in TACE/HAIC+TKI+PD-1(TACE/HAIC TP) group than TKI+PD-1 (TP) group. The incidence of AEs was acceptable. Conclusion: The triple therapy of TACE/HAIC TP had better efficacy for uHCC than TP, with acceptable security. [ABSTRACT FROM AUTHOR]

Background: Portal vein tumor thrombosis (PVTT) signifies late-stage hepatocellular carcinoma (HCC) with high-risk progression and poor prognosis. As a standard treatment, sorafenib monotherapy has limited the efficacy in managing HCC with PVTT. Currently, both hepatic arterial infusion chemotherapy (HAIC) and the combination of camrelizumab and rivoceranib have shown favorable survival benefits for advanced HCC, surpassing the standard sorafenib treatment. In this study, we investigate the safety and efficacy of HAIC combined with camrelizumab and rivoceranib in treating HCC patients with PVTT. Methods: From January 2020 to December 2021, HCC patients with PVTT, who received either a triple regime of HAIC combined with camrelizumab and rivoceranib or a dual regime of camrelizumab and rivoceranib as their first-line treatment, were reviewed for eligibility at four hospital centers in China. To balance any intergroup differences, propensity score matching (PSM) was applied. The aim of this study is to compare the efficacy of the dual and triple combination treatment regimens based on survival prognosis and tumor response and evaluate the safety based on the occurrence of adverse reactions. Result: In this study, a total of 411 patients who received either the triple treatment regime (HAIC combined with camrelizumab plus rivoceranib, referred to as the HAICCR group, n = 292) or the dual treatment regime (camrelizumab combined with rivoceranib, referred to as the CR group, n = 119) between January 2020 and December 2021 were included. The results showed that the HAICCR group exhibited significantly better overall survival (mOS: 19.60 months vs. 11.50 months, p < 0.0001) and progression-free survival (mPFS: 10.0 months vs. 5.6 months, p < 0.0001) compared to the CR group in the overall cohort. Moreover, the HAICCR group also had a significantly higher ORR (objective response rate, 55.5% vs. 42.0%, p = 0.013) and DCR (disease control rate, 89.0% vs. 79.0%) compared to the CR group. After PSM, a final matched cohort of 83 pairs was obtained, and the survival benefits were consistent in this cohort as well (mOS: 18.70 months vs. 11.0 months, p < 0.0001; mPFS: 10.0 months vs. 5.6 months, p < 0.0001). However, there was no significant difference in the ORR between the triple and dual combination regimes. Univariate and multivariate analysis showed that CTP (Child–Turcotte–Pugh) stage, ALBI (albumin–bilirubin index) grade, tumor number, and treatment regime were significant risk factors affecting overall survival, while AFP (α-fetoprotein) level, tumor number, metastasis, and treatment regime were significant risk factors affecting progression-free survival. As for safety, hypertension and hand–foot syndrome were the two most common adverse reactions in both groups, with no significant difference in the occurrence of adverse reactions between the two groups (p < 0.05). Conclusion: In the context of advanced HCC patients with PVTT, the combination regime of HAIC and camrelizumab plus rivoceranib demonstrates more excellent capacity for prolonging survival and offers a well-tolerated safety compared to the CR dual therapy approach. This triple regime represents a therapeutic modality of broad prospects and vast potential for HCC patients with PVTT. [ABSTRACT FROM AUTHOR]

The study used propensity score matching (PSM) to reduce selectivity bias. Overall survival (OS) and progression-free survival (PFS) were compared using Kaplan‒Meier curves with the Log rank test. The objective response rate (ORR), conversion surgery rate (CSR) adverse event (AE) comparison and subgroup analysis were performed between the two groups.Results: After PSM 1:1, 444 patients were divided into two groups. The patients with hHCC who received HAIC had higher median PFS (6.1 vs 3.3 months, P < 0.001) and OS (10.3 vs 8.2 months, P=0.303) than TACE. Higher ORR (24.8% vs 11.7%) and CSR (15.5% vs 8.9%) were found in the HAIC group than in the TACE group (both P < 0.05). The incidence of grade 3/4 AE was 23.9% and 8.1% in the TACE and HAIC groups, respectively. The subgroup analysis suggest that HAIC appeared to particularly benefit patients with tumor diameter of more than 10 centimeters (hazard ratio [HR], 0.6; 95% CI, 0.47– 0.77; p, 0.00) and PVTT Vp4 (HR, 0.56; 95% CI, 0.39– 0.8; P, 0.01) for PFS outperforming TACE.Conclusion: HAIC can provide better disease control for hHCC than cTACE, with a comparable long-term OS and safety.Keywords: hepatocellular carcinoma, transarterial chemoembolization, hepatic artery infusion chemotherapy, high risk

Background: Patients with hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT) present a poor prognosis. Current systemic therapies offer limited benefits. Hepatic artery infusion chemotherapy (HAIC) is a local regional treatment for advanced HCC, particularly in selected patients such as patients with PVTT or high intrahepatic tumor burden. Objectives: The purpose of this study is to retrospectively evaluate the efficacy and safety of HAIC combined with anti-PD-1 immunotherapy for HCC patients with PVTT, and explore factors related to survival prognosis, providing clues for treatment decisions for HCC patients. Design: This is a single-center retrospective study conducted over 2 years on consecutive PVTT patients receiving HAIC combined anti-PD-1 antibodies. Methods: The primary endpoint was overall survival (OS). Univariate and multivariate analyses were performed to identify prognostic factors affecting OS. Treatment-associated adverse events were evaluated as well. Results: A total of 119 patients were analyzed. The median OS and PFS were 14.9 months and 6.9 months. A total of 31.1% of grade 3–4 adverse events were reported, with elevated transaminase and total bilirubin being the most common. The independent variables correlated with survival include treatment-related alpha-fetoprotein (AFP) response, the presence of extrahepatic organ metastasis, absolute value of platelet (PLT), neutrophil-to-lymphocyte ratio, and combined usage of tyrosine kinase inhibitors (TKIs). Conclusion: In HCC patients with PVTT, combination therapy with HAIC and anti-PD-1 antibodies might be a promising therapy. The efficacy and safety of this combination protocol on patients with HCC complicated by PVTT warrants further investigation prospectively, especially in combination with TKIs.

Objective: This study aimed to evaluate the efficacy and safety of sequential treatment of continuous transcatheter hepatic artery infusion chemotherapy (HAIC) with systemic capecitabine monotherapy and camrelizumab for treating unresectable hilar cholangiocarcinoma (HCCA). Methods: This study retrospectively analyzed patients with unresectable HCCA admitted to Linyi Cancer Hospital in Shandong Province from October 2019 to December 2021. All enrolled patients were treated with HAIC (mFOLFOX7) + camrelizumab for 2-6 cycles and administered systemic therapy with capecitabine and camrelizumab. The objective response rate (ORR), disease control rate (DCR), and adverse reactions of patients were assessed. The Kaplan-Meier method was used to describe overall survival (OS), and univariate and multivariate Cox regression models were utilized to analyze the influencing factors of OS. Results: This study included 34 patients, ORR was 61.76% (21/34), and DCR was 97.06% (33/34) after two HAIC cycles. The median follow-up time was 17.5 months, with an average of 18.32 ± 8.06 months, and the median OS was 20.0 months. HAIC-related adverse reactions included mainly gastrointestinal symptoms and hematological toxicity caused by chemotherapy drugs, all of which were grades 1-2. Further, adverse events for camrelizumab treatment included fatigue, skin rash, and hypothyroidism, all of which were grade <3. Cox regression analysis revealed that the periductal infiltrating type of growth pattern indicated a worse OS, whereas more HAIC cycles (5 ~ 6) were a protective factor for OS. Conclusion: HAIC sequentially combined with systemic capecitabine chemotherapy and a programmed death-1 inhibitor displayed favorable effects for unresectable HCCA, with controllable adverse reactions.

Background: Hepatic artery infusion chemotherapy (HAI) has been proposed as a valuable adjunct for multimodal therapy of primary and secondary liver malignancies. This review provides an overview of the currently available evidence of HAI, taking into account tumor response and long-term oncologic outcome. Summary: In colorectal liver metastases (CRLM), HAI in combination with systemic therapy leads to high response rates (85–90%) and conversion to resectablity in primary unresectable disease in up to 50%. HAI in combination with systemic therapy in CRLM in the adjuvant setting shows promising long-term outcomes with up to 50% 10-year survival in a large, non-randomized single-center cohort. For hepatocellular carcinoma patients, response rates as high as 20–40% have been reported for HAI and long-term outcomes compare well to other therapies. Similarly, survival for patients with unresectable intrahepatic cholangiocarcinoma 3 years after treatment with HAI is reported as high as 34%, which compares well to trials of systemic therapy where 3-year survival is usually below 5%. However, evidence is mainly limited by highly selected, heterogenous patient groups, and outdated chemotherapy regimens. The largest body of evidence stems from small, often non-randomized cohorts, predominantly from highly specialized single centers. Key Message: In well-selected patients with primary and secondary liver malignancies, HAI might improve response rates and, possibly, long-term survival. Results of ongoing randomized trials will show whether a wider adoption of HAI is justified, particularly to increase rates of resectability in advanced malignant diseases confined to the liver.

Objective: To compare the efficacy and safety of hepatic arterial infusion chemotherapy (HAIC) with transarterial chemoembolization (TACE) for the treatment of high-risk hepatocellular carcinoma (hHCC) patients. Methods: Between January 2014 and August 2022, a total of 1765 consecutive patients with hHCC who underwent initial intraarterial therapies were reviewed and divided into a TACE group (n, 507) and a HAIC group (n, 426). The study used propensity score matching (PSM) to reduce selectivity bias. Overall survival (OS) and progression-free survival (PFS) were compared using Kaplan? Meier curves with the Log rank test. The objective response rate (ORR), conversion surgery rate (CSR) adverse event (AE) comparison and subgroup analysis were performed between the two groups. Results: After PSM 1:1, 444 patients were divided into two groups. The patients with hHCC who received HAIC had higher median PFS (6.1 vs 3.3 months, P < 0.001) and OS (10.3 vs 8.2 months, P=0.303) than TACE. Higher ORR (24.8% vs 11.7%) and CSR (15.5% vs 8.9%) were found in the HAIC group than in the TACE group (both P < 0.05). The incidence of grade 3/4 AE was 23.9% and 8.1% in the TACE and HAIC groups, respectively. The subgroup analysis suggest that HAIC appeared to particularly benefit patients with tumor diameter of more than 10 centimeters (hazard ratio [HR], 0.6; 95% CI, 0.47-0.77; p, 0.00) and PVTT Vp4 (HR, 0.56; 95% CI, 0.39-0.8; P, 0.01) for PFS outperforming TACE. Conclusion: HAIC can provide better disease control for hHCC than cTACE, with a comparable long-term OS and safety. [ABSTRACT FROM AUTHOR]

Objective: To assess the effectiveness and safety of transarterial chemoembolization (TACE) in combination with hepatic artery infusion chemotherapy (HAIC)? PD-1 inhibitors, and tyrosine kinase inhibitors(TKI) for unresectable hepatocellular carcinoma (HCC). Methods: A retrospective analysis was performed on 158 unresectable HCC patients admitted to the First Affiliated Hospital of Nanchang University between May 2019 and October 2022. The patients were split into two groups based on the type of treatment they received: TACE combined with HAIC, PD-1 and TKI group (THPK) and TACE combined with PD-1 and TKI group (TPK). The response was evaluated using modified solid tumor Efficacy Assessment Criteria (mRECIST). Kaplan-Meier curves were used to analyze the overall survival (OS). OS-influencing factors were identified using the Cox proportional risk regression model. Results: Finally, 63 patients who received THPK treatment and 60 patients who had TPK treatment were included. The THPK group had higher DCR (77.78% vs. 55.00%, P=0.007) and ORR (20.63% vs. 13.34%, P=0.282) than the TPK group did. The survival analysis curve also showed that the median OS was substantially longer in the THPK group than in the TPK group (OS: 21 months vs. 14 months, P=0.039). After multivariate Cox regression-corrected analysis, extrahepatic metastases (P=0.002) and methemoglobin >400 (P=0.041) were adverse influences on OS, but the THPK group (relative to the TPK group) was an independent favorable prognostic factor for OS (P=0.027). The results of the subgroup analysis showed that the addition of HAIC therapy to TPK treatment in patients with BCLC stage C, age ≤60 years, ECOG grade 0 and lobular distribution of tumors prolonged overall survival time and improved prognosis. Except for nausea, there was no difference in the adverse events between the two groups. Conclusion: In patients with unresectable HCC, the THPK group had a longer OS and similar adverse events compared to the TPK group. In the future, TACE-HAIC in combination with targeted and immunotherapy may be a more effective therapeutic option for hepatocellular carcinoma that cannot be surgically removed.

Objectives: To evaluate the efficacy and safety of biliary stenting implantation with iodine-125 seed strand (SI) followed by hepatic artery infusion chemotherapy (HAIC) plus lenvatinib (Len) with programmed death-1 (PD-1) inhibitor for patients diagnosed with extrahepatic cholangiocarcinoma (ECC) and malignant obstructive jaundice (MOJ). Methods: In this single-center retrospective study, the data of ECC patients with MOJ from March 2015 to January 2023 was assessed. Using probability score matching (PSM), the selection bias of patients was reduced. Primary study outcomes included overall survival (OS) and progression-free survival (PFS). The OS and PFS were performed using the Kaplan-Meier method and evaluated with the log-rank test. Results: A total of 104 patients were enrolled finally, including 52 patients treated with interventional therapy (SI+HAIC) plus Len with PD-1 inhibitor (SI+HAIC+Len+P group) and 52 patients treated with interventional therapy (SI+HAIC) plus lenvatinib (SI+HAIC+Len group). 26 pairs of patients were matched after PSM analysis. After PSM analysis, the median OS and PFS in the SI+HAIC+Len+P group were significantly longer compared to those in the SI+HAIC+Len group (OS:16.6 vs. 12.3 months, P = 0.001; PFS:12.6 vs 8.5 months, P = 0.004). The DCR was significantly different between groups (P = 0.039), while ORR not (P = 0.548). The addition of PD-1 inhibitor was generally well tolerated without treatmentassociated mortality. Conclusion: Interventional therapy (SI+HAIC) plus Len with PD-1 inhibitor was effective for ECC patients accompanied by MOJ with a manageable safety profile. [ABSTRACT FROM AUTHOR]

Abstract Objective: This study’s purpose was to evaluate the response, safety and overall survival of trans-arterial infusion chemotherapy in patients with advanced hepatocellular carcinoma with preserved hepatic function. Methods: This study was carried out on 25 patients, diagnosed with hepatocellular carcinoma (HCC) combined with portal vein tumor thrombosis (PVTT) and underwent hepatic artery infusion chemotherapy (HAIC). Radiological investigations as Triphasic CT or dynamic MRI liver assessment pre and post therapy were acquired. Intra-Arterial chemotherapeutic agent infusion using only doxorubicin was performed. Results: Neither of the patients who underwent HAIC developed complete or partial response. Only one patient (4.8%) from 21 patients under HAIC had stable disease. 20 patients (95%) had progressive disease. Progressive disease was in form of progression at the primary tumor site in form of increased focal lesion size, number or vascular invasion. Vascular invasion was seen in one patient (4.8%) in the form of hepatic vein thrombosis. Mean progression free survival was about 2.24 ± 0.88 months. Mean overall survival was about 5.72 ± 0.89 months. Conclusion: Our study demonstrated lower clinical efficacy and lower disease control rate of repeated HAIC using doxorubicin only infusion in case of advanced HCC with PVT as compared to combined doxorubicin and cisplatin in previous studies as well as the standard therapy with sorafenib.

Simple Summary: We aimed to compare the prognosis of patients with advanced hepatocellular carcinoma treated with the first-line atezolizumab plus bevacizumab (AB) combination chemotherapy and the less popular locoregional treatment mainly used in East Asia, hepatic artery infusion chemotherapy (HAIC). We conducted a retrospective study with 114 patients treated with AB and 193 patients treated with HAIC and compared the overall survival (OS) and progression-free survival (PFS). Our results showed comparable OS between the two therapy groups; however, PFS was superior in patients treated with AB combination therapy. After compensating for confounding variables via propensity score matching, there was no significant difference in PFS and OS between the two groups. This study aimed to compare the prognosis and characteristics of patients with advanced hepatocellular carcinoma treated with first-line atezolizumab plus bevacizumab (AB) combination therapy and hepatic artery infusion chemotherapy (HAIC). We retrospectively assessed 193 and 114 patients treated with HAIC and AB combination therapy, respectively, between January 2018 and May 2023. The progression-free survival (PFS) of patients treated with AB combination therapy was significantly superior to that of patients treated with HAIC (p < 0.05), but there was no significant difference in overall survival (OS). After propensity score matching, our data revealed no significant differences in OS and PFS between patients who received AB combination therapy and those who received HAIC therapy (p = 0.5617 and 0.3522, respectively). In conclusion, our propensity score study reveals no significant differences in OS and PFS between patients treated with AB combination therapy and those treated with HAIC. [ABSTRACT FROM AUTHOR]

Advanced hepatocellular carcinoma (HCC) has a very low resectable rate. This meta-analysis aimed to compare efficacy of three combination strategies in treatment of advanced unresectable HCC with a view of guiding future selection of the best combination therapy for sorafenib and local therapy. A search was conducted to identify relevant literature published between April 2013 and May 2022, and then compared efficacy of sorafenib combined with external radiotherapy (SOF + RT), sorafenib with transarterial chemoembolization (SOF + TACE), sorafenib with hepatic artery infusion chemotherapy (SOF + HAIC), sorafenib (SOF), external radiotherapy (RT), transarterial chemoembolization (TACE), and hepatic artery infusion chemotherapy (HAIC) were studied and analyzed. Finally, the results were statistically analyzed using R 3.5.3 software and Stata/SE 15.0 software. A total of 46 studies, involving 7595 patients, were included in the meta-analysis. Analysis of overall survival (OS) and progression-free survival (PFS) of seven related treatment interventions revealed that the combination therapy had significantly higher efficacy than monotherapies. Among the combination therapies, SOF + RT was associated with the best OS and PFS rates, and the least adverse events compared to the other treatment modalities. The efficacy of combination therapy was better than monotherapy. In combination therapy, the overall survival time and progression-free survival time of SOF + RT were longer, and the adverse reactions were less. Therefore, SOF + RT may be the best choice for sorafenib combined with local therapy. [ABSTRACT FROM AUTHOR]

Primary liver cancer is a common and lethal malignancy in China. Transcatheter arterial chemoembolization (TACE) is globally recognized as the preferred treatment modality for the non-surgical resection of hepatocellular carcinoma (HCC), while transcatheter arterial infusion (TAI) is another effective interventional treatment for HCC. In recent years, hepatic arterial infusion chemotherapy (HAIC) has gained increasing attention as an application-regulated modality for TAI. Owing to the current debate in the medical community regarding the use of HAIC and TACE for the treatment of HCC, the application of both approaches should be considered at a higher level, with a broader perspective and a more normative aspect. Accordingly, we aimed to define the rational combination of liver cancer TAI/HAIC with TACE as infusion transcatheter chemoembolization (iTACE), which suggests that the two interventions are not superior but lead to a mutually beneficial situation. In this review, we sought to discuss the development, specification, application, challenge and innovation, debate, and union of TAI/HAIC and TACE, and the clinical application and latest research on iTACE. We aimed to introduce new concepts of iTACE and expect new breakthroughs in the treatment of liver cancer owing to the combined use of the two major interventional tools.

Purpose of the study was to evaluate the safety and feasibility of preoperative chemotherapy in intrahepatic cholangiocarcinoma (IHCC).Patients and methods. A total of 171 liver resections for IHCC were performed between 2007 and 2021, of which 24 were preceded by preoperative therapy (14.0 %). Systemic therapy was conducted in 11 patients (45.8 %). Regional chemotherapy was provided to 13 patients (54.2 %). In two cases, regional chemotherapy was supplemented with systemic therapy.Results. A significant increase in the proportion of patients with clinical stage IIIb and higher was observed in the group of patients who had received preoperative therapy (83.3 % vs. 35.4 %, p < 0.0001). Complications of preoperative therapy occurred in 45.8 % of patients, with grade three and above complications identified in three patients (12.5 %). The incidence of postoperative complications (37.5 % vs. 42.9 %, p = 0.79), post‑resection liver failure (8.3 % vs. 13.6 %, p = 0.7) and postoperative mortality (4.2 % vs. 3.4 %, p = 0.68) in the preoperative therapy group were similar to those in the control group. The rate of radical resections was also identical, 83 % in both groups (p = 0.8). The relapses rates within the first six months after the surgery were similar: 25 % of patients in both groups (p = 0.62). The median OS reached 36 months in the main group and 32 months in the control one (p = 0.81).Conclusion. Since the main group predominantly included patients with more advanced stages of the disease and yet the treatment resulted in comparable immediate and long‑term outcomes, it can be concluded that preoperative therapy can be justified in patients with IHCC who have factors predisposing to poor prognosis. Randomized trials are necessary to determine the rationality, as well as the type and regimen of preoperative therapy to be used in patients with IHCC.

Introduction: Liver surgery leads to a high degree of heterogeneity in the prognosis of hepatocellular carcinoma (HCC) patients. However, most previous studies focused on the postoperative therapeutic effects of other treatments, with relatively few studies on the impacts on liver function. This study investigated the impact of transarterial chemoembolization (TACE) and hepatic artery infusion chemotherapy (HAIC) on liver function after HCC resection from various angles. Methods: 138 HCC patients were enrolled, including 27 patients who received TACE and 80 patients who received HAIC. Besides routine treatment such as liver protection and antiviral therapy, 31 patients received no other treatment. The different groups were compared with various biological parameters with four types of scoring methods. Results: In the short term after TACE, the mean (±SD) alanine transaminase and aspartate transaminase values increased by 79.22 ± 117.43 U/L and 66.33 ± 94.54 U/L, respectively (p < 0.01). The mean (±SD) total bilirubin (TBIL) values increased by 4.02 ± 6.08 μmol/L (p < 0.01). The mean (±SD) albumin (ALB) values decreased by 3.54 ± 2.93 g/L (p < 0.001). The mean (±SD) albumin bilirubin (ALBI) scores increased by 0.39 ± 0.22 (p < 0.001). In the short term after HAIC, the mean (±SD) TBIL values increased by 2.11 ± 5.57 μmol/L (p < 0.01). The mean (±SD) ALB values decreased by 2.52 ± 3.26 g/L (p < 0.001), and the mean (±SD) ALBI scores increased by 0.21 ± 0.42 (p < 0.001). In both treatment groups, the long-term liver function was not significantly different from that before treatment and also from that of the untreated group (p > 0.05). Conclusion: TACE after HCC resection has a significant impact on short-term liver function, whereas HAIC has a relatively small impact, but neither has a major impact on long-term liver function.

Background: The subsequent therapy for hepatocellular carcinoma (HCC) patients with refractory to transarterial chemoembolization (TACE) is still controversial. This study was performed to evaluate the efficacy and safety of combination therapy comprising hepatic artery infusion chemotherapy (HAIC), lenvatinib, and programmed death-1 inhibitors relative to HAIC combined with lenvatinib. Methods: In this single-center retrospective study, we analyzed data from HCC patients with refractory to TACE from June 2017 to July 2022. Primary study outcomes were overall survival (OS) and progression-free survival (PFS), while the secondary outcomes were the objective response rate (ORR), disease control rate (DCR), and treatment-related adverse events. Results: We enrolled 149 patients finally, including 75 patients who received HAIC combined with lenvatinib plus PD-1 inhibitors therapy (HAIC+L+P group) and 74 patients who received HAIC combined with lenvatinib therapy (HAIC+L group). The median OS in the HAIC+L+P group (16.0; 95% CI: 13.6~18.3 months) was significantly higher compared to the HAIC+L group (9.0; 95% CI: 6.5~11.4 months) (p = 0.002), while the median PFS in the HAIC+L+P group (11.0; 95% CI: 8.6~13.3 months) was significantly higher compared to the HAIC+L group (6.0; 95% CI: 5.0~6.9 months) (p < 0.001). Significant between-group differences in DCR (p = 0.027) were found. Additionally, 48 pairs of patients were matched after propensity matching analysis. The survival prognosis between two groups before propensity matching is similar to that after propensity matching. Moreover, the percentage of patients with hypertension in the HAIC+L+P group was significantly higher compared to the HAIC+L group (28.00% vs. 13.51%; p = 0.029). Conclusions: A combination therapy of HAIC, lenvatinib, and programmed death-1 inhibitors significantly improved oncologic response and prolonged survival duration, showing a better survival prognosis for HCC patients with refractory toTACE.

Background: This study aimed to establish and validate nomograms to predict the probability of recurrence and recurrence-free survival (RFS) in patients with hepatocellular carcinoma (HCC) after conversion hepatectomy based on hepatic arterial infusion chemotherapy (HAIC). Methods: Nomograms were constructed using data from a retrospective study of 214 consecutive patients treated with HAIC- based conversion liver resection between January 2016 and July 2020. Nomograms predicting the probability of tumor recurrence and RFS were established based on predictors selected by multivariate regression analysis. Predictive accuracy and discriminative ability of the nomogram were examined. Bootstrap method was used for internal validation. External validation was performed using cohorts (n = 128) from three other centers. Results: Recurrence rates in the primary and external validation cohorts were 63.6 and 45.3%, respectively. Nomograms incorporating clinicopathological features of tumor recurrence and RFS were generated. Concordance index (C-index) scores of the nomograms for predicting recurrence probability and RFS were 0.822 (95% CI, 0.703-0.858) and 0.769 (95% CI, 0.731-0.814) in the primary cohort, and 0.802 (95% CI, 0.726-0.878) and 0.777 (95% CI, 0.719-0.835) in the external validation cohort, respectively. Calibration curves indicated good agreement between the nomograms and actual observations. Moreover, the nomograms outperformed the commonly used staging systems. Patients with low risk, stratified by the median nomogram scores had better RFS (low risk vs. high risk, 36.5 vs. 5.2 months, P < 0.001). The external validation cohort supported these findings. Conclusions: The presented nomograms showed favorable accuracy for predicting recurrence probability and RFS in HCC patients treated with HAIC-based conversion hepatectomy. Identifying risk factors and estimating tumor recurrence may help clinicians in the decision-making process regarding adjuvant therapies for patients with HCC, which eventually achieves better oncological outcomes.

Introduction: For patients with advanced hepatocellular carcinoma (HCC), hepatic artery infusion chemotherapy (HAIC) is a common and mature treatment, but the safety and efficacy of HAIC combined with lenvatinib for advanced HCC patient treatment remains unclear. Therefore, this study compared the safety and efficacy of HAIC with or without lenvatinib in unresectable HCC patients. Methods: We retrospectively analyzed 13 unresectable advanced HCC patients who received HAIC monotherapy or combination therapy of HAIC and lenvatinib. Overall survival (OS), disease control rate (DCR), objective response rate (ORR), progression-free survival (PFS), incidence of adverse events (AEs), and changes in liver function were compared between the two groups. We applied a Cox regression analysis to evaluate the independent risk factors affecting survival outcomes. Results: The ORR in the HAIC+lenvatinib group was markedly increased compared to the HAIC group (p < 0.05), while the DCR in the HAIC group was higher (p > 0.05). No notable difference was found between the two groups in median OS and PFS (p > 0.05). Compared to the HAIC+lenvatinib group, more patients had improved liver function in the HAIC group after treatment, but the difference was not dramatical (p > 0.05). The AEs incidence was 100.00% in both groups, which was relieved with corresponding treatment. Besides, Cox regression analysis did not identify independent risk factors related to OS and PFS. Conclusion: Combination therapy of HAIC and lenvatinib notably performed better than the HAIC monotherapy in patients with unresectable HCC in terms of ORR and was well tolerated, which deserves further investigation with large-scale clinical trials.

Portal vein tumor thrombosis (PVTT) is associated with aggressive tumor biology (high grade), high tumor burden (number and size of lesions), high levels of serum markers (AFP), poor liver function (deranged LFT), and poor performance status of patients. The Barcelona Clinic Liver Cancer staging system places HCC patients with PVTT in advanced stage (BCLC Stage-C). This group contains a fairly heterogeneous patient population, previously considered candidates for palliative systemic therapy with sorafenib. However, this provided modest overall survival (OS) benefit. The results of a recent Phase III (IMbrave150) trial favor the combination of atezolizumab and bevacizumab over sorafenib as a standard of care in advanced unresectable HCC. While only lenvatinib proved to be non-inferior against sorafenib in a phase III (REFLECT trial), regorafenib (RESORCE trial), ramucirumab (REACH-2), and cabozantinib (CELESTIAL) have been approved second-line therapy in phase III clinical trials. Recently, the data on the prospect of other modalities in the management of HCC with PVTT is mounting with favorable results. Targeting multiple pathways in the HCC cascade using a combination of drugs and other modalities such as RT, TACE, TARE, and HAIC appear effective for systemic and loco-regional control. The quest for the ideal combination therapy and the sequence set is still widely unanswered and prospective trials are lacking. With the armament of available therapeutic options and the advances and refinements in the delivery system, down-staging patients to make them eligible for curative resection has been reported. In a rapidly evolving treatment landscape, performing surgery when appropriate, in the form of LR and even LT to achieve cure does not seem farfetched. Likewise, adjuvant therapy and prompt management of the recurrences holds the key to prolong OS and DFS. This review discusses the management options of HCC patients with PVTT.Keywords: hepatocellular carcinoma, portal vein tumor thrombosis, systemic therapy, transarterial chemoembolization, hepatic artery infusion chemotherapy, radiotherapy, multimodality treatment, liver resection, liver transplantation

However, the combination of the two treatments has not been reported. In this study, we compared the efficacy of HAIC combined with anti-PD-1 immunotherapy (HAICAP) and HAIC in patients with advanced HCC.Methods: Between November 2018 and December 2019, advanced HCC patients that were treated with either HAICAP or HAIC were retrospectively recruited and reviewed for eligibility. Efficacy was evaluated according to tumor response and survival.Results: As a result, 229 patients were included in this study. Patients were divided into HAICAP group (n = 81) and HAIC group (n = 148) accordingly. The follow-up time ranged from 1.0 to 21.6 months, with a median of 11.0 months. The median overall survival was 18.0 months in the HAICAP group and 14.6 months in the HAIC group (p = 0.018; HR = 0.62; 95% CI 0.34– 0.91). The median progression-free survival was 10.0 months in the HAICAP group and 5.6 months in the HAIC group (p = 0.006; HR = 0.65; 95% CI 0.43– 0.87). The disease control rate in overall response (83% vs 66%; p = 0.006) and intrahepatic response (85% vs 74%, respectively; p = 0.045) were higher in the HAICAP group than in the HAIC group.Conclusion: In comparison to HAIC, HAICAP was associated with a better treatment response and survival benefits for patients with advanced HCC.Keywords: hepatocellular carcinoma, hepatic artery infusion chemotherapy, programmed cell death protein-1, FOLFOX, combination therapy

Aim: To evaluate the feasibility of computed tomography (CT) - derived measurements of body composition parameters to predict the risk factor of non-objective response (non-OR) in patients with hepatocellular carcinoma (HCC) undergoing anti-PD-1 immunotherapy and hepatic artery infusion chemotherapy (immune-HAIC). Methods: Patients with histologically confirmed HCC and treated with the immune-HAIC were retrospectively recruited between June 30, 2019, and July 31, 2021. CT-based estimations of body composition parameters were acquired from the baseline unenhanced abdominal CT images at the level of the third lumbar vertebra (L3) and were applied to develop models predicting the probability of OR. A myosteatosis nomogram was built using the multivariate logistic regression incorporating both myosteatosis measurements and clinical variables. Receiver operating characteristic (ROC) curves assessed the performance of prediction models, including the area under the curve (AUC). The nomogram's performance was assessed by the calibration, discrimination, and decision curve analyses. Associations among predictors and gene mutations were also examined by correlation matrix analysis. Results: Fifty-two patients were recruited to this study cohort, with 30 patients having a OR status after immune-HAIC treatment. Estimations of myosteatosis parameters, like SM-RA (skeletal muscle radiation attenuation), were significantly associated with the probability of predicting OR (P =0.007). The SM-RA combined nomogram model, including serum red blood cell, hemoglobin, creatinine, and the mean CT value of visceral fat (VFmean) improved the prediction probability for OR disease with an AUC of 0.713 (95% CI, 0.75 to 0.95) than the clinical model nomogram with AUC of 0.62 using a 5-fold cross-validation methodology. Favorable clinical potentials were observed in the decision curve analysis. Conclusions: The CT-based estimations of myosteatosis could be used as an indicator to predict a higher risk of transition to the Non-OR disease state in HCC patients treated with immune-HAIC therapy. This study demonstrated the therapeutic relevance of skeletal muscle composition assessments in the overall prediction of treatment response and prognosis in HCC patients. [ABSTRACT FROM AUTHOR]

A high proportion of massive patients with hepatocellular carcinoma (HCC) are not amenable for surgical resection at initial diagnosis, owing to insufficient future liver remnant (FLR) or an inadequate surgical margin. For such patients, portal vein embolization (PVE) is an essential approach to allow liver hypertrophy and prepare for subsequent surgery. However, the conversion resection rate of PVE only is unsatisfactory because of tumor progression while awaiting liver hypertrophy. We report here a successfully treated case of primary massive HCC, where surgical resection was completed after PVE and multimodality therapy, comprising hepatic artery infusion chemotherapy (HAIC), Lenvatinib plus Sintilimab. A pathologic complete response was achieved. This case demonstrates for the first time that combined PVE with multimodality therapy appears to be safe and effective for massive, potentially resectable HCC and can produce deep pathological remission in a primary tumor.

Background: To systematically identify the long-term efficacy of postoperative adjuvant hepatic artery infusion chemotherapy (HAIC) for patients with hepatocellular carcinoma (HCC). Methods: PubMed, MedLine, Embase, the Cochrane Library, and Web of Science were searched to collect the eligible studies up to March 31, 2021, that compared the surgical resection (SR) versus SR+HAIC for HCC patients. The endpoints were overall survival (OS) rates and disease-free survival (DFS) rates, and the effect size was determined by hazard ratio (HR) with 95% CI. Results: A total of 12 studies (two randomized controlled trials (RCTs) and 10 non-RCTs) including 1,333 patients were eligible for this meta-analysis. The pooled results showed that OS and DFS rates in the SR+HAIC group were both better than those in the SR alone group (HR = 0.56, 95% CI = 0.41–0.77, p < 0.001; HR = 0.66, 95% CI = 0.55–0.78, p < 0.001, respectively). Furthermore, the subgroup analysis showed that patients would benefit from SR+HAIC regardless of chemotherapy regimens and courses (all p < 0.05), and patients with microvascular or macrovascular invasion would also benefit more from SR+HAIC in terms of OS and DFS (all p < 0.05). Conclusion: Postoperative adjuvant HAIC could improve the long-term prognosis of HCC patients, especially for those with microvascular or macrovascular invasion, regardless of chemotherapy regimens and courses, but it deserves further validation.

BackgroundIt is controversial whether adjuvant treatment could be recommended for hepatocellular carcinoma (HCC) after curative hepatectomy. Thus, we performed a network meta-analysis (NMA) to assess adjuvant treatment’s benefit and determine the optimal adjuvant regimen.MethodsWe systematically searched PubMed, Embase, and Cochrane Library for randomized controlled trials comparing adjuvant therapy versus no active treatment after curative hepatectomy among patients with HCC. Pooled data on recurrence and overall survival (OS) were analyzed within pairwise meta-analysis and NMA.ResultsTwenty-three eligible trials (3,940 patients) reporting eight treatments were included. The direct meta-analysis showed that adjuvant therapy prevented the recurrence (OR = 0.65; 95% CI: 0.55, 0.77; P = 0.177; I2 = 21.7%) and contributed to OS (HR = 0.63; 95% CI: 0.54, 0.73; P = 0.087; I2 = 31.1%) in comparison to the observation. In the NMA, internal radiotherapy (IRT; OR = 0.55; 95% CI: 0.39, 0.77; SUCRA = 87.7%) followed by hepatic artery infusion chemotherapy (HAIC; OR = 0.6; 95% CI: 0.36, 0.97; SUCRA = 77.8%), and HAIC (HR = 0.44; 95% CI: 0.21, 0.87; SUCRA = 82.6%) followed by IRT (HR 0.54; 95% CI:0.36, 0.81; SUCRA = 69.7%) were ranked superior to other treatments in terms of preventing recurrence and providing survival benefit, respectively.ConclusionsThe addition of adjuvant therapy lowers the risk of recurrence and provide survival benefit after surgical resection for HCC. HAIC and IRT are likely to be the two most effective adjuvant regimens.Systematic Review Registrationhttps://inplasy.com/inplasy-2020-11-0039/.

Background: Hepatic arterial infusion chemotherapy (HAIC) is one option for treating massive tumors and unresectable hepatocellular carcinoma (HCC). However, there is a lack of remedial treatment after these treatments are ineffective or failed. Summary: Some studies have discovered that HAIC has greater survival in patients with advanced HCC. A previous study has shown that HAIC is effective in the treatment of advanced HCC, and the data on randomized clinical trials are limited and unclear. Key Message: More clinical trials and research are needed in order to make HAIC a standard and recommended therapy for advanced HCC. Our review focuses on the clinical applications of hepatic artery infusion treatment. [ABSTRACT FROM AUTHOR]

Atezolizumab/bevacizumab is the first line of treatment for unresectable hepatocellular carcinoma (HCC), combining immune checkpoint inhibitor and anti-VEGF monoclonal antibodies. Hepatic arterial infusion chemotherapy (HAIC) is administered when the above-described combination fails to confer sufficient clinical benefit. The present study aimed to explore the association between tumor programmed cell death-ligand 1 (PD-L1) positivity and HAIC response. A total of 40 patients with HCC who had undergone HAIC with available biopsy samples obtained between January 2020 and May 2023 were retrospectively enrolled. Tumor response, progression-free survival (PFS), disease control rate (DCR) and overall survival (OS) were evaluated. PD-L1 expression in tumor samples was assessed using a combined positivity score. The response rates of HAIC-treated patients with advanced HCC after failure of atezolizumab/bevacizumab combination therapy were recorded. OS (P=0.9717) and PFS (P=0.4194) did not differ between patients with and without PD-L1 positivity. The objective response rate (P=0.7830) and DCR (P=0.7020) also did not differ based on PD-L1 status. In conclusion, the current findings highlight the consistent efficacy of HAIC, regardless of PD-L1 positivity. [ABSTRACT FROM AUTHOR]

Hepatic artery infusion chemotherapy (HAIC) has good clinical efficacy in the treatment of advanced hepatocellular carcinoma (HCC); however, its efficacy varies. This review summarized the ability of various markers to predict the efficacy of HAIC and provided a reference for clinical applications. As of October 25, 2023, 51 articles have been retrieved based on keyword predictions and HAIC. Sixteen eligible articles were selected for inclusion in this study. Comprehensive literature analysis found that methods used to predict the efficacy of HAIC include serological testing, gene testing, and imaging testing. The above indicators and their combined forms showed excellent predictive effects in retrospective studies. This review summarized the strategies currently used to predict the efficacy of HAIC in middle and advanced HCC, analyzed each marker's ability to predict HAIC efficacy, and provided a reference for the clinical application of the prediction system., Competing Interests: Conflict-of-interest statement: The authors declare that they have no conflict of interest to declare., (©The Author(s) 2024.

BackgroundThis study aimed to investigate the influence of hepatic artery infusion chemotherapy (HAIC) on hepatitis B virus (HBV) reactivation in hepatitis B surface antigen (HBsAg) positive patients with primary hepatocellular carcinoma (HCC) as well as evaluate the role of antiviral prophylaxis in these patients.MethodsWe enrolled 170 HBsAg-positive advanced HCC patients receiving HAIC using mFOLFOX regimen, of which 137 patients received antiviral prophylaxis. Risk factors for HBV reactivation were analyzed. The overall survival (OS) from the first application of HAIC were compared between antiviral and non-antiviral groups.ResultsA total of 25 patients (14.7%) developed HBV reactivation after HAIC, of which 16 patients received antiviral treatment and nine patients did not. The incidence of HBV reactivation was 11.7% (16/137) in antiviral group and 27.3% (9/33) in non-antiviral group respectively. No antiviral prophylactic was the only significant risk factor for HBV reactivation (OR=12.35, 95% confidence interval (CI) 4.35–33.33, p

BackgroundLenvatinib combined with programmed cell death protein-1 (PD-1) inhibitors has resulted in good survival outcomes in the treatment of unresectable hepatocellular carcinoma (HCC). Hepatic artery infusion chemotherapy (HAIC) has also attracted attention due to its high response rates and favorable survival for advanced HCC patients. The present study aimed to compare the efficacy of HAIC combined with PD-1 inhibitors plus lenvatinib (HPL) and PD-1 inhibitors plus lenvatinib (PL) in patients with advanced HCC.MethodsBetween July 2018 and December 2019, patients diagnosed with advanced HCC who initially received HPL or PL treatment were reviewed for eligibility. Efficacy was evaluated according to tumor response and survival.ResultsIn total, 70 patients met the criteria and were included in the present study, and they were divided into the HPL group (n = 45) and PL group (n = 25). The overall response rate (40.0 vs. 16.0%, respectively; p = 0.038) and disease control rate (77.6 vs. 44.0%, respectively; p < 0.001) were higher in the HPL group than in the PL group. The median overall survival was 15.9 months in the HPL group and 8.6 months in the PL group (p = 0.0015; HR = 0.6; 95% CI 0.43–0.83). The median progression-free survival was 8.8 months in the HPL group and 5.4 months in the PL group (p = 0.0320; HR = 0.74; 95% CI 0.55–0.98).ConclusionCompared to PL, HPL was associated with a significantly better treatment response and survival benefits for patients with advanced HCC.
