Introduction: In uveal melanoma (UM) patients with hepatic metastases, hepatic artery infusion chemotherapy (HAIC) is a viable, palliative treatment option. To evaluate the impact of two histomorphological patterns (spindle cell vs. epithelioid) of liver metastases on median overall survival (mOS) in UM patients undergoing HAIC. Methods: A retrospective analysis with 60 UM patients (29 females, mean age: 61.6 ± 12.1 years) with hepatic metastases was performed. Histomorphological patterns in metastases were analysed and classified as either predominant spindle cell or epithelioid pattern. mOS between both patient groups was analysed using Kaplan–Meier curves and the log‐rank test. Results: In 73.3% (44/60) of the metastases, a predominant epithelioid pattern, in 21.7% (13/60) a predominant spindle cell pattern, and in 5% (3/60) other patterns were found. No significant differences between patients with an epithelioid (mOS: 14.2 months, 95% CI: 8.8–19.6) and a spindle cell pattern (mOS: 14.4 months, 95% CI: 4.3–24.5) were detected by the log‐rank test, χ2(2) = 0.22, P = 0.881. Conclusion: Histomorphological patterns of UM metastases do not seem to be a predictor for mOS in UM patients undergoing HAIC. [ABSTRACT FROM AUTHOR]

Background: The first-line treatment for advanced hepatocellular carcinoma has evolved significantly. This study aimed to identify the most beneficial regimen. Methods: A systematic search was conducted from July 2012 to August 2024 across the following four databases: PubMed, Embase, Cochrane Library, and ClinicalTrials.gov. This search focused on phase III prospective randomized controlled trials that compared first-line treatment for advanced hepatocellular carcinoma. Results: Seventeen studies involving 10322 patients were included in this network meta-analysis. Of the studies we included, twelve studies were global multicenter clinical studies, four were initiated in China, and one was initiated in Korea. The results of our statistical analysis suggest that Hepatic artery infusion chemotherapy with oxaliplatin plus fluorouracil (HAIC-FO) demonstrated significant overall survival (OS) benefits compared with most treatments, including various immune checkpoint inhibitors (ICIs) and anti-vascular endothelial growth factor tyrosine kinase inhibitors (VEGF-TKIs). In terms of OS, HAIC had shown similar efficacy with sorafenib plus FOLFOX (HR, 0.88; 95% CI: 0.37-2.09) and transcatheter arterial chemoembolization (TACE) combined with lenvatinib (HR, 0.69; 95% CI: 0.30-1.56). Notably, immune-related treatments, such as ICIs combined with anti-VEGF therapies, also showed improved OS compared with anti-VEGF-TKIs alone. In terms of progression-free survival (PFS), HAIC-FO outperformed anti-VEGF-TKI monotherapy, ICI monotherapy, and several ICI combinations. However, it was not superior to lenvatinib plus TACE or lenvatinib plus pembrolizumab. Based on the Surface Under the Cumulative Ranking Curve (SUCRA) values, HAIC-FO was ranked the most effective in terms of OS (SUCRA = 0.961) and objective response rate (ORR) (SUCRA = 0.971). The results of the subgroup analysis suggested that HAIC-FO achieved the best OS benefit in the macrovascular invasion (MVI) and extrahepatic spread (EHS) subgroup (SUCRA = 0.99) and that tremelimumab combined with durvalumab achieved the best OS benefit in the Asian subgroup (SUCRA = 0.88). Conclusion: This systematic review and network meta-analysis suggest that HAIC-based therapies may become a potential first-line treatment option for advanced HCC, especially for patients in Mainland China with MVI and EHS. Additionally, immune-related treatments may be more suitable for Asian populations. [ABSTRACT FROM AUTHOR]

Background: Hepatocellular carcinoma (HCC) is the most common primary liver cancer and often arises in the context of chronic liver disease, such as hepatitis B or C infection, and cirrhosis. Advanced unresectable HCC (uHCC) presents significant treatment challenges due to its advanced stage and inoperability. One efficient treatment method for advanced uHCC is the use of hepatic arterial infusion chemotherapy (HAIC) combined with transcatheter arterial embolization (TAE). Patients and Methods: In this study, we conducted a retrospective collection of clinical data, including basic information, radiological data, and blood test parameters, for patients with advanced uHCC who underwent TAE + HAIC treatment from August 2020 to February 2023. A total of 743 cases involving 262 patients were included. Ultimately, the covariates included in the analysis were the Child-Pugh score, extrahepatic metastasis, tumor number, tumor size, and treatment method. Results: In the study, we performed univariable and multivariable analysis on 23 clinical factors that were screened by LASSO regression, indicating that the five variables aforementionedly were identified as independent factors influencing patient prognosis. Then we developed a nomogram of the sensitive model and calculated concordance indices of prognostic survival models. Conclusion: Based on the uHCC patient cohort, we have developed a prognostic model for OS in patients who received TAE + HAIC treatment. This model can accurately predict OS and has the potential to assist in personalized clinical decision-making. [ABSTRACT FROM AUTHOR]

Currently, the combination therapy of tyrosine kinase inhibitors (TKIs) and programmed cell death protein-1 (PD-1) inhibitors has become the mainstream treatment. According to multiple clinical guidelines, it is strongly advised to consider local therapy as the primary treatment choice for uHCC. This research was conducted to examine the safety and effectiveness of combining hepatic arterial infusion chemotherapy (HAIC) with TKIs and PD-1 inhibitors for the treatment of uHCC.Methods: Between 2015 and 2020, 208 HCC patients received HAIC alone or HAIC in combination with TKIs and PD-1 inhibitors. The overall survival(OS), and progression-free survival(PFS) and the best treatment response were compared between the two treatment groups. Propensity score matching (PSM)was used to minimize confounding bias.Results: Among the enrolled patients, 116 patients (55.8%) received combination therapy, while 92 patients (44.2%) received HAIC alone. The baseline characteristics were similar between the two groups. After PSM, 82 pairs of well-matched liver cancer patients were selected; the overall response rate in the combination group trended better than that in the HAIC alone group. The hazard ratios (HRs) for OS and PFS of the combination approach compared to the HAIC-alone approach were 0.47 (95% CI, 0.322– 0.687; p< 0.001) and 0.58 (95% CI, 0.397– 0.848; p=0.005), respectively.Conclusion: For uHCC patients, combination therapy can provide better OS and PFS compared to HAIC alone.Keywords: hepatocellular carcinoma, TKIs, PD-1, HAIC, combination therapy

Our objective was to evaluate the cost-effectiveness of SoHAIC versus sorafenib for the treatment of HCC-Vp3-4, taking into account the viewpoint of Chinese healthcare payers.Methods: This pharmacoeconomic study employed a Markov model to assess the cost-effectiveness of treating HCC-Vp3-4 with SoHAIC in comparison to sorafenib. The patient characteristics were drawn from individuals from the trial conducted between June 2017 and November 2019, with cost and health value data sourced from published literature. The primary outcome measure in this research was the incremental cost-effectiveness ratio (ICER), which indicates the additional cost per quality-adjusted life year (QALY). The willingness-to-pay (WTP) threshold per QALY was set at &dollar;30,492.00. Furthermore, 1-way sensitivity and probabilistic sensitivity analyses were carried out to validate the consistency of the results.Results: In the baseline scenario, sorafenib resulted in 0.42 QALY at a cost of &dollar;10,507.89, while SoHAIC generated 1.66 QALY at a cost of &dollar;32,971.56. When comparing SoHAIC to sorafenib, the ICER was &dollar;18,237.20 per QALY, which was below the WTP threshold per QALY. Furthermore, the 1-way sensitivity analysis demonstrated that the ICER remained within the WTP threshold despite fluctuations in variables. In the probabilistic sensitivity analysis, SoHAIC had a 98.8% probability of being cost-effective at the WTP threshold, considering a wide range of parameters.Conclusion: In this cost-effectiveness evaluation, SoHAIC demonstrated cost-effectiveness over sorafenib for HCC with major portal vein tumor thrombosis, as observed from the perspective of a Chinese payer.Keywords: HCC, portal vein tumor thrombosis, sorafenib, HAIC, Cost-effectiveness

Purpose: To evaluate the efficacy and safety of mFOLFOX-based hepatic arterial infusion chemotherapy (HAIC) combined with tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibitors (ICIs) in the treatment of advanced hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) Methods: This retrospective study included patients who received mFOLFOX-based HAIC combined with TKIs and ICIs from January 2021 to January 2023. The primary outcome was the objective response rate of PVTT response, and the secondary outcomes were 6-month, 1-year survival rate, overall survival (OS), and corresponding adverse events and complications were also evaluated. PVTT responses were assessed using ITK-SNAP software. Results: A total of 37 patients were included in the analysis, 18.92% achieved a complete response and 56.76% achieved a partial response in PVTT response. The objective response rate (ORR) of PVTT was 75.68%. The 6-month survival rate was 89%, the 1-year survival rate was 66%, and the median OS was 15.8 months. In univariate analysis, Child-Pugh score (P=0.010) was important factor for predicting OS; in multivariate analysis, Child-Pugh score (P=0.015, HR= 3.089, 95%CI: 1.250--7.633) was the important factor for predicting OS. In terms of adverse reactions, the most common adverse reactions associated with HAIC are pain and thrombocytopenia associated with oxaliplatin. Conclusion: FOLFOX-based HAIC combined with TKIs and ICIs induced an objective response rate of 75.68% in PVTT. Clinical signicance: FOLFOX-based HAIC combined with TKIs and ICIs provides more treatment options for PVTT. [ABSTRACT FROM AUTHOR]

IntroductionGemcitabine and cisplatin remain the cornerstone for the treatment of advanced or unresectable biliary tract cancers, but the incidence rate of the grade 3 or 4 toxic effects is high (70.7%). In recent years, significant progress has been achieved in the systemic treatment of cholangiocarcinoma with immune checkpoint inhibitors (ICIs), targeted therapy, and hepatic artery infusion chemotherapy (HAIC). HAIC may elevate the local drug concentration in the liver to 10–100 times the drug plasma concentration; therefore, it may enhance tumor cytotoxicity while minimizing systemic adverse effects. HAIC combined with immunotherapy and targeted therapy resulted in acceptable tumor responses and tolerable toxic effects in the treatment of hepatocellular carcinoma (HCC). However, whether this combination strategy can benefit patients with unresectable intrahepatic cholangiocarcinoma remains unclear.Methods and AnalysisWe describe a single-arm, open label, prospective clinical trial of HAIC sequential transcatheter arterial embolization (TAE) combined with tislelizumab and surufatinib in patients with unresectable intrahepatic cholangiocarcinoma. TAE + HAIC was performed at an interval of at least 3 weeks, and oxaliplatin (85 mg/m2) and rituximab (3 mg/m2) were infused. TAE was performed using undrugged microspheres. Tislelizumab was infused every 3 weeks and surufatinib was administered orally once a day, with 3-5 capsules (50 mg/capsule) each time. We plan to enroll 28 participants in this study. The primary study endpoint was objective response rate (ORR). The secondary endpoints were progression-free survival (PFS), conversion to surgical resection rate, overall survival (OS), 1-year OS rate, disease control rate (DCR), quality of life (QoL), and incidence of adverse events.Trial registration numberNCT06239532.

BackgroundThe five-year recurrence rate for patients with hepatocellular carcinoma (HCC) is as high as 70%. Patients with high-risk recurrence factors experience significantly poorer prognosis. Local regional therapies, including transarterial chemoembolisation (TACE), hepatic arterial infusion chemotherapy (HAIC), radiotherapy, and emerging immunotherapy, are commonly used adjuvant treatment options. We conducted an indirect comparison of these adjuvant therapies for such patients.MethodsWe conducted a systematic search in public databases for relevant studies and assessed the efficacy and safety of the corresponding therapies by consolidating disease-free survival (DFS), overall survival (OS), and adverse events (AEs).ResultsA total of eight randomised controlled trials were ultimately included. The Gelman-Rubin plot and kernel density estimation indicate that the stability of the combined model is satisfactory.Conclusionimmunotherapy is not inferior to local regional therapies in delaying tumour recurrence, however, the higher incidence of AEs remains a significant concern. Adjuvant radiotherapy demonstrated superior efficacy in delaying tumour recurrence compared to adjuvant TACE, although further support from phase III clinical trial evidence is required.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/, identifier CRD42024576316.

Abstract Background The treatment of hepatocellular carcinoma (HCC) patients exhibiting high-risk characteristics (Vp4, and/or bile duct invasion, and/or tumor occupancy ≥ 50%) lacks standardized approaches and yields unfavorable results. This study endeavors to evaluate the safety, efficacy, and prognostic impacts of employing hepatic arterial infusion chemotherapy (HAIC), lenvatinib, and humanized programmed death receptor-1 (PD-1) in the treatment of high-risk HCC patients. Methods In this retrospective analysis, HCC patients with high-risk features were treated with either lenvatinib combined with PD-1 (LEN-PD1) or a combination of HAIC, lenvatinib, and PD-1 (HAIC-LEN-PD1). The study assessed the antitumor efficacy by calculating overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and disease control rate (DCR). Treatment-related adverse events (TRAEs) were analyzed to assess the safety profiles. Results Between June 2019 and September 2022, a total of 61 patients were included in the LEN-PD1 group, while 103 patients were enrolled in the HAIC-LEN-PD1 group. The OS was 9.8 months in the LEN-PD1 group, whereas the HAIC-LEN-PD1 group exhibited a significantly longer median OS of 19.3 months (HR = 0.43, p

Hepatic artery infusion chemotherapy (HAIC) is a popular treatment modality for the treatment of colorectal liver metastasis (CRLM). The aim of this study was to determine the feasibility of HAIC for high-risk resected CRLM delivered using repeated femoral puncture and delivering 5-fluorouracil infusional chemotherapy along with systemic adjuvant chemotherapy. The present study is a retrospective review of a prospectively maintained database. All patients who underwent HAIC for colorectal liver metastases between July 2022 and July 2023 were included. A total of 12 patients were included in the study of which 11 completed four sessions as planned. The median age was 47 (29–73) years with nine male (81%) and two female (18%) patients. Rectum (n = 7, 63%) was the most common primary location. All patients received systemic chemotherapy with 5-fluorouracil-based regimens prior to HAIC (median 12 cycles). The median number of metastasis was 2 (1–8). Eight patients had metastasis in unilobar distribution (73%). On completion of HAIC treatment, nine patients (64%) were completely disease free with a median follow-up of 8 months. None of the patients experienced any immediate adverse events during or after completion of the procedure. Conventional HAIC comes with various challenges such as unavailability of the agent floxuridine and the specialized HAIC pump. Percutaneous HAIC has a lower chance of infection. The delivery of HAIC using repeated femoral punctures and 5FU chemotherapy was successful in over 90% of the patients making it a feasible option in the treatment of CRLM. [ABSTRACT FROM AUTHOR]

The OS was 9.8 months in the LEN-PD1 group, whereas the HAIC-LEN-PD1 group exhibited a significantly longer median OS of 19.3 months (HR = 0.43, p < 0.001). Furthermore, PFS was notably extended in the HAIC-LEN-PD1 group compared to the LEN-PD1 group (9.6 months vs. 4.9 months, HR = 0.48, p < 0.001). Patients in the HAIC-LEN-PD1 group had a higher ORR and DCR according to the modified RECIST (76.7% vs. 23.0%, p < 0.001; 92.2% vs. 72.1%, p = 0.001). HAIC-LEN-HAIC group led to more adverse events than LEN-PD1 group, most of which were tolerable and controllable. Conclusion: Lenvatinib, HAIC and PD-1 showed safe and promising anti-tumor activity compared with lenvatinib alone for HCC with high-risk features. Key points: • HAIC-LEN-PD1 combination treatment for HCC. • HAIC-LEN-PD1 is a safe and effective treatment for high-risk patients with HCC. • HAIC-LEN-PD1 is more effective than LEN-PD1 in prolonging patient survival.

Treatment-related adverse events (TRAEs) were analyzed to assess the safety profiles.Results: Between February 2020 and July 2022, 97 patients were enrolled in this retrospective cohort study. The median follow-up time was 447 days. During analysis, 65 patients had disease progression, and 39 patients died. The median PFS and OS were 295 and 579 days, respectively. According to RECIST 1.1 and mRECIST, the ORR was 64.9% and 78.3%, respectively, and the DCR was 92.8%. The median and intrahepatic DOR was 363 and 462 days, respectively. Treatment-related grade 3 or 4 adverse events occurred in 64 (65.9%) patients, and the most common adverse events were hypertension (9.3%), thrombocytopenia (7.2%), and elevated aspartate transaminase (7.2%). Participants with low levels of serum procalcitonin (PCT) had satisfactory prognosis.Conclusion: Lenvatinib, HAIC, and PD-1 were safe and showed promising antitumor activity against HCC with high-risk features. The initial levels of procalcitonin might be the predictive biomarkers for the combined treatment.Keywords: hepatocellular carcinoma, HAIC, lenvatinib, VP4, PD-1

Systemic therapy remains the primary therapeutic approach for advanced hepatocellular carcinoma (HCC). Nonetheless, its efficacy in achieving control of intrahepatic lesions is constrained. Hepatic arterial infusion chemotherapy (HAIC) is a therapeutic approach that combines localized treatment with systemic antitumor effects, which aim is to effectively manage the progression of cancerous lesions within the liver, particularly in patients with portal vein tumor thrombosis (PVTT). Combining HAIC with anti-programmed cell death protein 1 (anti-PD-1) monoclonal antibody (mAb) immunotherapy is anticipated to emerge as a novel therapeutic approach aimed at augmenting the response inside the localized tumor site and achieving prolonged survival advantages. In order to assess the effectiveness, safety, and applicability of various therapeutic modalities and to address potential molecular mechanisms underlying the efficacy of HAIC-sensitizing immunotherapy, we reviewed the literature about the combination of HAIC with anti-PD-1 mAb therapies.

Background/purpose: The prognosis of hepatocellular carcinoma (HCC) patients with portal vein tumor thrombus (PVTT) is generally poor and hepatectomy is optional for these patients. This study aims to explore the survival benefits of neoadjuvant hepatic arterial infusion chemotherapy (HAIC) for resectable HCC with PVTT. Methods: This retrospective study included 120 resectable HCC patients with PVTT who underwent hepatectomy, from January 2017 to January 2021 at Sun Yat-sen University Cancer Center. Of these patients, the overall survival (OS) and recurrence-free survival (RFS) of 55 patients who received hepatectomy alone (Surgery group) and 65 patients who received neoadjuvant HAIC followed by hepatectomy (HAIC-Surgery group) were compared. Logistic regression analysis was conducted to develop a model predicting the response to neoadjuvant HAIC. Results: The OS rates for the HAIC-Surgery group at 1, 3, and 5 years were 94.9%, 78%, and 66.4%, respectively, compared with 84.6%, 47.6%, and 37.2% in the Surgery group (p < 0.001). The RFS rates were 88.7%, 56.2%, and 38.6% versus 84.9%, 38.3%, and 22.6% (p = 0.002). The subgroup analysis revealed that the survival benefit of neoadjuvant HAIC was limited to patients who responded to it. The logistic model, consisting of AFP and CRP, that predicted the response to neoadjuvant HAIC performed well, with an area under the ROC curve (AUC) of 0.756. Conclusion: Neoadjuvant HAIC followed by hepatectomy is associated with a longer survival outcome than hepatectomy alone for HCC patients with PVTT and the survival benefit is limited to patients who respond to neoadjuvant FOLFOX-HAIC.

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

Of 98 enrolled patients, 37 patients were classified as potentially resectable. We compared the potentially resectable population (PRP) with the non-potentially resectable population (NPRP). The primary study endpoint was conversion rate, and secondary endpoints included progression-free survival (PFS), overall survival (OS), objective response rate (ORR), disease control rate (DCR), and safety.Results: The baseline characteristics were comparable between populations except for a higher proportion of patients with extrahepatic metastases in the NPRP versus PRP (23/61 [37.7%] vs 3/37 [8.1%], respectively; p=0.003). For PRP, the ORR was 67.6% based on RECIST v1.1 (75.7% based on mRECIST), conversion rate was 40.5% (15/37). Of the 15 patients who underwent surgical resection, three achieved complete pathological remission. The median follow-up for all patients was 28 months (range: 2– 47). For NPRP, the ORR was 22.9% based on RECIST v1.1 (31.1% based on mRECIST), The median PFS for PRP was significantly longer than that of NPRP (25 vs 13 months, p = 0.0025). The median OS for PRP was significantly longer than that of NPRP (not reached VS 21 months, p=0.014). Hypertension was the most common grade ≥ 3 adverse reaction in both PRP and NPRP. No new safety signals were observed for any of the treatments.Conclusion: The triple-combination therapy of lenvatinib plus sintilimab plus arterially-directed therapy can convert potentially unresectable HCC into resectable disease and improve long-term survival.Keywords: lenvatinib, sintilimab, conversion therapy, unresectable hepatocellular carcinoma, TACE, HAIC

In order to assess the effectiveness, safety, and applicability of various therapeutic modalities and to address potential molecular mechanisms underlying the efficacy of HAIC-sensitizing immunotherapy, we reviewed the literature about the combination of HAIC with anti-PD-1 mAb therapies.

Abstract Background Hepatic arterial infusion chemotherapy (HAIC) with oxaliplatin and 5-fluorouracil was effective in unresectable hepatocellular carcinoma (HCC). The program of FOLFOX-HAIC in HCC was performed for 1 day (HAIC 1d) or 2 days (HAIC 2d). We hereby retrospectively compared the efficacy and safety between these two treatment regimens and explored the predictive power of thymidylate synthase (TYMS), an enzyme involved in the DNA synthesis process and metabolism of fluorouracil. Methods This study included patients with a primary diagnosis of unresectable HCC. These patients received HAIC for 1 day or 2 days. The overall survival (OS), progression-free survival (PFS), tumor response, and adverse events were compared. The propensity score matching (PSM) was used to reduce bias. Peripheral blood samples before the treatments were collected and used to measure the concentration of TYMS through enzyme-linked immunosorbent assay (ELISA). ELISA was performed according to the manufacturers’ guidelines. Results We included 368 patients for this study: 248 in the HAIC 1d group and 120 in the HAIC 2d group. There was no significant difference of OS between the two groups (14.5 for HAIC 1d vs 15.3 months for HAIC 2d, p=0.46). Compared with the HAIC 1d group, the HAIC 2d group did not prolong the PFS (7.3 vs 7.5 months, p=0.91) or elevate the tumor response (42.5% vs 39.1%, p=0.53) per RECIST 1.1. In the PSM cohort, the efficacy between the two groups was similar. The total frequencies of grade 3–4 events were higher with the HAIC 2d group than with the HAIC 1d group, especially in the PSM cohort (p=0.043). Additionally, patients with TYMS low level might benefit longer OS from the HAIC 2d group (18.7 vs 13.6 months, p=0.014). Conclusions There was not much of a difference in efficacy between the two groups, but the HAIC for 1 day might be safer, which needed further research. The level of TYMS might be the predictive biomarkers.

To investigate efficacy and safety of hepatic arterial infusion chemotherapy combined with lenvatinib (HAIC-Len) and HAIC alone for the treatment of advanced hepatocellular carcinoma (Ad-HCC). Totally 349 patients with Ad-HCC participated in the research from February 2018 to October 2020. On the basis of propensity score matching (PSM), 132 and 110 cases were assigned to the HAIC group and the HAIC-Len group, respectively, with a ratio of 1:1. Progression-free survival (PFS), overall survival (OS), and complications were compared between two groups. The Kaplan–Meier method and log-rank test were utilized to estimate cumulative OS and PFS. Additionally, uni- and multi-variate Cox regression models were employed to identify significant independent factors. The median follow-up period in this study was set to be 20.8 months. Following PSM, the one-, two- and three-year cumulative OS rates in the HAIC-Len and HAIC groups were 63.6%, 12.1%, and 3.0%, and 47.2%, 11.8%, and 2.7%, respectively, with a significant difference (P < 0.001). The first-three-year cumulative incidence rates PFS in the HAIC-Len and the HAIC groups were 15.2%, 1.5%, and ND, and 11.8%, 4.5%, and 3.6%, respectively, with no significant difference detected (P = 0.092). BMI (HR 0.709. 95% CI 0.549, 0.915. P = 0.008) and AST (HR 1.005. 95% CI 1.003, 1.007. P < 0.001) represented independent prognostic factors for OS. Additionally, the two groups exhibited no significant difference in the incidence rates of adverse events. HAIC-Len significantly improved survival outcomes of patients with Ad-HCC and demonstrated acceptable toxicity compared to HAIC alone. [ABSTRACT FROM AUTHOR]

Background: Lenvatinib combined with programmed cell death protein-1 inhibitor has achieved good survival results in the treatment of hepatocellular carcinoma with portal vein tumor thrombus. Transarterial chemoembolization (TACE) or hepatic arterial infusion chemotherapy (HAIC) has attracted attention because of its high response rate and favorable survival rate in patients with liver cancer and portal vein tumor thrombus. This study aimed to compare the efficacy and safety of Lenvatinib combined with programmed cell death protein-1 inhibitor plus transarterial chemoembolization or hepatic arterial infusion chemotherapy in patients with hepatocellular carcinoma with portal vein tumor thrombus. Method: We searched PubMed, Embase and the Cochrane Library for studies. These included randomized controlled trials or clinical trials of Lenvatinib plus programmed cell death protein-1 inhibitor plus transarterial chemoembolization or hepatic arterial infusion chemotherapy (intervention group) versus Lenvatinib plus programmed cell death protein-1 inhibitor or Lenvatinib plus transarterial chemoembolization/hepatic arterial infusion chemotherapy or Lenvatinib alone (control group) in liver cancer with portal vein tumor thrombus The primary outcomes were overall survival and progression-free time, and the secondary outcomes were response rate and the rate of adverse events. According to the heterogeneity among different studies, Revman5.4 was used to conduct fixed effect or random effect model analysis. Results: Five clinical trials were included, including 311 cases in the intervention group and 309 cases in the control group. In terms of efficacy, compared with the control group, the overall survival (HR=1.88, 95%CI: 1.57-2.25, P < 0.00001) and progression-free survival (HR=1.62, 95%CI: 1.41-1.86, P < 0.00001), better efficacy, and better disease response than the control group. In terms of safety, the risk of treatment-related adverse events in the intervention group was higher than that in the control group, and White Blood cell count decreased (RR=0.72, 95%CI: 0.38-1.37, P=0.32), Platelet count decreased (RR=0.99, 95%CI: 0.65-1.51, P=0.96) and Total bilirubin increased (RR=0.86, 95%CI: Increased) 0.88-1.28, P=0.46) were lower than those in the control group, and the rest were higher than those in the control group, and the differences in some results were statistically significant. Conclusions: Transarterial chemoembolization or hepatic arterial infusion chemotherapy combined with Lenvatinib plus programmed cell death protein-1 inhibitor can effectively delay the progression, prolong the survival period and improve the quality of life of liver cancer patients with portal vein tumor thrombus.

MethodsThis was a single-arm historical cohort study of ESCC patients with synchronous or heterochronous LM between December 2014 and July 2021 at the Department of Gastrointestinal Oncology. The patients were treated with HAIC for LM, and regular image assessments were performed according to the judgment of the interventional physician. Liver progression-free survival (PFS), liver objective response rate (ORR), liver disease control rate (DCR), overall survival (OS), adverse events (AEs), treatment information, and basic characteristics were observed retrospectively.ResultsOverall, a total of 33 patients were enrolled in this study. All included patients received catheterized HAIC therapy, with a median of three (ranging from 2 to 6) sessions. The treatment response of liver metastatic lesions included partial response (PR) in 16 (48.5%) patients, stable disease (SD) in 15 (45.5%) patients, and progressive disease (PD) in two (6.1%) patients, for an ORR of 48.5% and a DCR of 93.9%. The median liver PFS was 4.8 months (95% confidence interval (CI): 3.0–6.6 months), and the median OS was 6.4 months (95% CI: 6.1–6.6 months). Patients who achieved PR at the liver metastasis site after HAIC were more likely to have a longer OS than those who achieved SD or PD. Grade 3 AEs occurred in 12 patients. The most common grade 3 AE was nausea, occurring in 10 (30.0%) patients, followed by abdominal pain in three (9.1%) patients. Only one patient showed grade 3 elevation of alanine aminotransferase (ALT)/aspartate aminotransferase (AST), and one patient suffered from grade 3 embolism syndrome AEs. Grade 4 adverse events, followed by abdominal pain, occurred in one patient.ConclusionHepatic arterial infusion chemotherapy might be an option as a regional therapy for ESCC patients with LM, as it is acceptable and tolerable.

Objective To investigate the effect of hepatic artery infusion chemotherapy combined with targeted and immunotherapy on hepatocellular carcinoma (HCC) with inferior vena cava tumor thrombus (IVCTT). Methods A case of hepatocellular carcinoma with tumor thrombus in the inferior vena cava (IVC) near the right atrium was treated with donafenib combined with hepatic artery infusion chemotherapy (HAIC) and sintilimab. The response of tumor treatment was evaluated by RECEST v1.1. The dynamic changes of alpha-fetoprotein (AFP) and PIVKA-Ⅱ were observed and the surgical procedure was introduced. Results After four cycles of treatment with donafenib combined with HAIC and sintilimab, the diameter of the tumor and the tumor thrombus in IVC were successfully reduced, and AFP was reduced to normal. Both tumor and tumor thrombus were completely removed by total hepatic vascular exclusion (THVE) with the IVC incision. Postoperative pathology showed complete remission of the tumor. Conclusion Donafenib combined with HAIC and sintilimab has a good tumor shrinking effect for HCC with IVCTT, and can be applied for conversion surgery for patients of HCC with IVCTT.

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

Background: The first-line treatment for advanced hepatocellular carcinoma has evolved significantly. This study aimed to identify the most beneficial regimen., Methods: A systematic search was conducted from July 2012 to August 2024 across the following four databases: PubMed, Embase, Cochrane Library, and ClinicalTrials.gov. This search focused on phase III prospective randomized controlled trials that compared first-line treatment for advanced hepatocellular carcinoma., Results: Seventeen studies involving 10322 patients were included in this network meta-analysis. Of the studies we included, twelve studies were global multicenter clinical studies, four were initiated in China, and one was initiated in Korea. The results of our statistical analysis suggest that Hepatic artery infusion chemotherapy with oxaliplatin plus fluorouracil (HAIC-FO) demonstrated significant overall survival (OS) benefits compared with most treatments, including various immune checkpoint inhibitors (ICIs) and anti-vascular endothelial growth factor tyrosine kinase inhibitors (VEGF-TKIs). In terms of OS, HAIC had shown similar efficacy with sorafenib plus FOLFOX (HR, 0.88; 95% CI: 0.37-2.09) and transcatheter arterial chemoembolization (TACE) combined with lenvatinib (HR, 0.69; 95% CI: 0.30-1.56). Notably, immune-related treatments, such as ICIs combined with anti-VEGF therapies, also showed improved OS compared with anti-VEGF-TKIs alone. In terms of progression-free survival (PFS), HAIC-FO outperformed anti-VEGF-TKI monotherapy, ICI monotherapy, and several ICI combinations. However, it was not superior to lenvatinib plus TACE or lenvatinib plus pembrolizumab. Based on the Surface Under the Cumulative Ranking Curve (SUCRA) values, HAIC-FO was ranked the most effective in terms of OS (SUCRA = 0.961) and objective response rate (ORR) (SUCRA = 0.971). The results of the subgroup analysis suggested that HAIC-FO achieved the best OS benefit in the macrovascular invasion (MVI) and extrahepatic spread (EHS) subgroup (SUCRA = 0.99) and that tremelimumab combined with durvalumab achieved the best OS benefit in the Asian subgroup (SUCRA = 0.88)., Conclusion: This systematic review and network meta-analysis suggest that HAIC-based therapies may become a potential first-line treatment option for advanced HCC, especially for patients in Mainland China with MVI and EHS. Additionally, immune-related treatments may be more suitable for Asian populations., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Li, Yang, Teng, Liu, Li and Qu.)

Objective: To analyze the radiation dose received by patients during hepatic artery infusion chemotherapy (HAIC) and transarterial chemoembolization (TACE) procedures and the related influencing factors. Methods: Data of 162 cases in the HAIC group and 230 cases in the TACE group were collected. The included covariates were Age (

• Efficacy and safety of TACE and HAIC combined with TKIs and PD-1 inhibitors in unresectable hepatocellular carcinoma (uHCC) were evaluated. • Key findings: median overall survival (OS) 18.2 months, progression-free survival (PFS) 9.2 months, objective response rate (ORR) 67.7 %, disease control rate (DCR) 90.3 %, and conversion surgery rate (CSR) 27.4 %. • Converted patients is superior to that of other enrolled patients on OS and PFS. • Main adverse events included transaminitis, nausea, and fever. • This combination therapy demonstrates effectiveness, particularly in enhancing survival post-surgery in uHCC patients.

This study aimed to assess the effectiveness and safety of transcatheter arterial chemoembolization (TACE) and hepatic artery infusion chemotherapy (HAIC) combined with tyrosine kinase inhibitors (TKIs) and programmed death-1 (PD-1) inhibitors in patients with initially unresectable hepatocellular carcinoma (uHCC). A retrospective study was conducted on patients diagnosed with initially uHCC who received combined treatment of TACE-HAIC combined with TKIs and PD-1 inhibitors from July 2020 to February 2023. The primary endpoints were overall survival (OS) and progression free survival (PFS) and adverse events (AEs). Objective response rate (ORR), disease control rate (DCR) and conversion surgery rate (CSR), whereas the secondary endpoints. After screening, a total of 62 patients were selected for this study. The overall median OS was 18.2 (95% CI 16.24–20.16) months and median PFS was 9.2 (95% CI 7.24–11.16) months. Based on the modified Response Evaluation Criteria in Solid Tumors (mRECIST) criteria and RECIST v1.1 criteria, ORR was 67.7% (42/62), and the DCR was 90.3% (56/62), the CSR was 27.4% (17/62). The most common treatment-emergent adverse events (TEAEs) were transaminitis (56.4%, 35/62), nausea and vomiting (43.5%, 27/62), thrombocytopenia (37.1%, 23/62), abdominal pain (33.9%, 21/62), and fever (33.9%, 21/62). TKIs combined with PD-1 inhibitors plus TACE-HAIC therapy represents an effective and tolerable treatment option in patients with uHCC. Patients undergoing surgery after combination therapy may have survival benefits. [ABSTRACT FROM AUTHOR]

Background: Hepatocellular carcinoma (HCC) is the most common primary liver cancer and often arises in the context of chronic liver disease, such as hepatitis B or C infection, and cirrhosis. Advanced unresectable HCC (uHCC) presents significant treatment challenges due to its advanced stage and inoperability. One efficient treatment method for advanced uHCC is the use of hepatic arterial infusion chemotherapy (HAIC) combined with transcatheter arterial embolization (TAE)., Patients and Methods: In this study, we conducted a retrospective collection of clinical data, including basic information, radiological data, and blood test parameters, for patients with advanced uHCC who underwent TAE + HAIC treatment from August 2020 to February 2023. A total of 743 cases involving 262 patients were included. Ultimately, the covariates included in the analysis were the Child-Pugh score, extrahepatic metastasis, tumor number, tumor size, and treatment method., Results: In the study, we performed univariable and multivariable analysis on 23 clinical factors that were screened by LASSO regression, indicating that the five variables aforementionedly were identified as independent factors influencing patient prognosis. Then we developed a nomogram of the sensitive model and calculated concordance indices of prognostic survival models., Conclusion: Based on the uHCC patient cohort, we have developed a prognostic model for OS in patients who received TAE + HAIC treatment. This model can accurately predict OS and has the potential to assist in personalized clinical decision-making., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Du, Sheng, Shi, Li, Liu, Tang, Liu and Zhang.)

Purpose: To evaluate the efficacy and safety of mFOLFOX-based hepatic arterial infusion chemotherapy (HAIC) combined with tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibitors (ICIs) in the treatment of advanced hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT)., Methods: This retrospective study included patients who received mFOLFOX-based HAIC combined with TKIs and ICIs from January 2021 to January 2023. The primary outcome was the objective response rate of PVTT response, and the secondary outcomes were 6-month, 1-year survival rate, overall survival (OS), and corresponding adverse events and complications were also evaluated. PVTT responses were assessed using ITK-SNAP software., Results: A total of 37 patients were included in the analysis, 18.92% achieved a complete response and 56.76% achieved a partial response in PVTT response. The objective response rate (ORR) of PVTT was 75.68%. The 6-month survival rate was 89%, the 1-year survival rate was 66%, and the median OS was 15.8 months. In univariate analysis, Child-Pugh score (P=0.010) was important factor for predicting OS; in multivariate analysis, Child-Pugh score (P=0.015, HR= 3.089, 95%CI: 1.250-7.633) was the important factor for predicting OS. In terms of adverse reactions, the most common adverse reactions associated with HAIC are pain and thrombocytopenia associated with oxaliplatin., Conclusion: FOLFOX-based HAIC combined with TKIs and ICIs induced an objective response rate of 75.68% in PVTT., Clinical Signicance: FOLFOX-based HAIC combined with TKIs and ICIs provides more treatment options for PVTT., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Liu, Zhang, Zhang, Chen, Yang and Liu.)

Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) can induce rapid hypertrophy of the liver remnant. However, with a background of liver cirrhosis or other chronic liver diseases, patients with a huge hepatocellular carcinoma (HCC) may sometimes face insufficiency of hepatocellular regeneration after associating liver partition and portal vein ligation for staged hepatectomy (ALPPS). Herein, we report a 56-year-old male with a vast HCC (13.3 × 8.5 × 13 cm) whose ratio of the future liver remnant (FLR)/standard liver volume (SLV) was 28.7% when the disease was first diagnosed. Inadequate hypertrophy of FLR was shown in postoperative volumetric assessment a month after stage I ALPPS. After multidisciplinary team discussion (MDT), the patient was decided to follow three courses of hepatic arterial infusion chemotherapy (HAIC) with oxaliplatin, fluorouracil, and leucovorin (FOLFOX4). The last HAIC was performed together with transhepatic arterial embolization (TAE). Finally, ratio of the FLR/SLV increased from 28.7% to 40% during three-month intervals, meeting the requirements of the surgery. Stage II ALPPS, right trisectionectomy, was then successfully performed. There was no recurrence at half years of follow-up. In our case, HAIC seems to be more potent than transcatheter arterial chemoembolization (TACE) in maintaining the hyperplasia of the liver remnant, reducing tumor load, and preventing tumor progression in patients with a large HCC during ALPPS procedure. HAIC, following the first step of ALPPS, a pioneering treatment modality aiming for inadequate hypertrophy of FLR induced by ALPPS, could be an alternative procedure for patients with a vast HCC in clinical practice.

Summary: Purpose Hepatic arterial infusion chemotherapy (HAIC) is one of the options to treat unresectable hepatocellular carcinoma (HCC). The majority of HCC patients suffer great pain in the course of HAIC treatment. To improve the quality of life and the efficacy of HAIC treatment, the causes of pain, the choice of an analgesic regimen, and the relationship between pain and prognosis of HCC were analyzed. Methods A total of 376 HCC patients under HAIC in our hospital were recriuted between March 2017 and September 2019. Multivariate linear regression analysis (stepwise) was used to calculate the potential factors related to the severe pain in HCC patients under HAIC. Analgesics treatments were carried out based on the results of the visual analogue scale (VAS) score which was used to evaluate the pain. Results The mean value of the VAS score is 3.604, which indicates that the pain in most patients is mild and endurable. Intra-arterial lidocaine injection is an effective method in most patients (96%, 361 of 376), and the total score of VAS is reduced from 1355 to 195 following lidocaine injection. Multivariate analysis suggestes that oxaliplatin (OXA) preparation time, hepatic artery diameter and OXA manufacturers (R2 = 0.859) are influential factors for pain scores. Conclusion This study demonstrates an effective way to systematically assess and ease pain in HCC patients with HAIC treatment. OXA preparation time, hepatic artery diameter, and OXA manufacturers are the potential influencing factors for pain. This work presented here will provide a detailed understanding of the clinical application of HAIC in advanced HCC patients. [ABSTRACT FROM AUTHOR]

The interested modalities included stereotactic body radiotherapy (SBRT) combined with transarterial chemoembolization (TACE), three-dimensional radiotherapy (3D-RT) combined with hepatic arterial infusion chemotherapy (HAIC) or TACE, TACE plus sorafenib, and use of SBRT, HAIC, sorafenib, and TACE alone. Methods: PubMed and Cochrane Library electronic databases were systematically searched for eligible studies published up to June 2017. We used network meta-analysis to compare the disease control rate (DCR) and severe adverse events for the eight interested regimens included in this analysis. Study quality was assessed following the Grading of Recommendations, Assessment, Development and Evaluations method. Results: Fifteen studies published between 2010 and 2016 involving a total of 2,359 patients were enrolled in this network meta-analysis. With indirect comparison of DCR and overall safety, the pooled results showed that RT plus HAIC was the most effective regimen in treating advanced HCC with portal vein tumor thrombosis, followed by RT plus TACE. HAIC alone and sorafenib combined with HAIC appeared least effective intervention regimens. The incidence of treatment-related adverse events of grade 3 or 4 occurred less in the patients who received SBRT alone compared with other interested regimens. Conclusion: 3D-RT combined with HAIC or TACE showed more favorable treatment responses compared with other regimens in advanced HCC patients with portal vein tumor thrombosis.

Abstract Background In patients with advanced hepatocellular carcinoma (HCC), evidence is unclear as to whether hepatic arterial infusion chemotherapy (HAIC) or sorafenib is superior. We performed a prospective, open-label, non-comparative phase II study to assess survival with HAIC or HAIC converted to sorafenib. Methods Fifty-five patients were prospectively enrolled. Patients received HAIC as a second course if they had complete response, partial response, or stable disease (SD) with an alpha fetoprotein (AFP) ratio 1 and a DCP ratio > 1 or disease progression. The primary endpoint was the 1-year survival rate. Secondary endpoints were the 2-year survival rate, HAIC response, survival rate among HAIC responders, progression-free survival, and adverse events. Results Of the 55 patients in the intent-to-treat population, the 1-year and 2-year survival rates were 64.0 and 48.3%, respectively. After the first course of HAIC, one (1.8%) patient showed complete response, 13 (23.6%) showed partial response, 30 (54.5%) had SD, and 10 (18.1%) patients had progressive disease. Twenty-three patients (41.8%) had SD with AFP ratios 1 and DCP ratios > 1. Thirty-seven patients (68.5%) were responders and 17 (30.9%) were non-responders to HAIC. In responders, the 1-year and 2-year survival rates were 78 and 62%, respectively. Conclusion Given the results of this study, this protocol deserves consideration for patients with advanced HCC. This trial was registered prospectively from December 12. 2012 to September 1. 2016.

High-Altitude Ice Crystals (HAIC) constitute a hazard to commercial aircraft flying near deep convective weather due to jet-engine power loss and air data probes malfunction. HAIC can stick to warm metal surfaces in jet-engines and cause engine surge, stall, flameout and rollback, power loss, as well as engine compressor damage due to ice shedding. Along with these events, disruption to aircraft systems are noted when HAIC are ingested into air data probes (Pitot tube and/or Total Air Temperature -TAT- sensor), causing erroneous measurements of temperature and air speed. Particularly, the TAT probe incorrectly reporting zero degrees Celsius or in error is known to be evidence of ice crystals in the atmosphere surrounding the aircraft. These TAT anomalies are due to the accumulation of ice crystals in the TAT sensor, producing a zero degrees Celsius reading, generating failures in airspeed indicators and acting as potential incident/accident precursors. In this paper, TAT events from pilot reports and Flight Data Monitoring (FDM) are analyzed. TAT FDM data analysis covers two types of engines, which are used on short, medium and long-range routes. The study includes eight aircraft fleet types. Based on these analyses, we present a sensor-failure-tolerant heuristic that generates a reliability indicator, founded on the differences between the TAT and the engine's inlet temperature sensors. It aims to provide early warnings to pilots regarding HAIC events and prevent potential data errors and system failures. • High-Altitude Ice Crystals (HAIC) can obstruct aircraft pitot probes during the cruise phase. • Total Air Temperature (TAT) probe anomalies are evidence of ice crystals in the atmosphere. • TAT events from pilot reports and Flight Data Monitoring are analyzed. • We present different heuristics that generates reliability indicators regarding TAT events. • Routes flying through the Inter-Tropical Convergence Zone are more likely to experience TAT events.

Systemic therapy remains the primary therapeutic approach for advanced hepatocellular carcinoma (HCC). Nonetheless, its efficacy in achieving control of intrahepatic lesions is constrained. Hepatic arterial infusion chemotherapy (HAIC) is a therapeutic approach that combines localized treatment with systemic antitumor effects, which aim is to effectively manage the progression of cancerous lesions within the liver, particularly in patients with portal vein tumor thrombosis (PVTT). Combining HAIC with anti-programmed cell death protein 1 (anti-PD-1) monoclonal antibody (mAb) immunotherapy is anticipated to emerge as a novel therapeutic approach aimed at augmenting the response inside the localized tumor site and achieving prolonged survival advantages. In order to assess the effectiveness, safety, and applicability of various therapeutic modalities and to address potential molecular mechanisms underlying the efficacy of HAIC-sensitizing immunotherapy, we reviewed the literature about the combination of HAIC with anti-PD-1 mAb therapies., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Ding, Wang, Qiu, Zhu, Wang, Zhao, Qiu, Wang, Lv and Qi.)

Objective: To compare the clinical efficacy and safety of transcatheter hepatic arterial infusion chemotherapy (HAIC) with those of sorafenib in the treatment of patients with hepatocellular carcinoma (HCC) of Barcelona Clinic Liver Cancer (BCLC) stage C.Methods: Potentially relevant studies comparing the clinical efficacy and safety of HAIC with those of sorafenib were searched using Medline, PubMed, Embase, Cochrane Library, and Chinese databases (Wanfang Data and China National Knowledge Infrastructure). Overall survival rate (OSR), tumor response rate, disease control rate (DCR), and serious adverse events (SAEs) were compared and analyzed. Pooled ORs with 95% CIs were calculated using either the fixed-effects model or the random-effects model. All statistical analyses were conducted using Review Manager (version 5.3) from the Cochrane Collaboration.Results: A total of 1,264 patients were included in this meta-analysis. The results of this study showed that HAIC was associated with significantly higher 1-, 2-, and 3-year OSRs than sorafenib (OR 1.88, 95% CI1-year: [1.27–2.78], P1-year=0.002; OR 2.15, 95% CI2-year: [1.06–4.37], P2-year=0.03; OR 7.90, 95% CI3-year: [2.12–29.42], P3-year=0.002). Compared to sorafenib, HAIC was associated with superior complete response (CR), partial response (PR), and objective response rate (ORR) (OR 3.90, 95% CICR: [1.89–8.03], PCR=0.0002; OR 3.47, 95% CIPR: [2.31–5.24], PPR,0.00001; OR 3.02, 95% CIOR: [2.05–4.45], POR,0.0001). There was no statistically significant difference between HAIC and sorafenib in stable disease (SD), progressive disease (PD), DCR, and SAEs (OR 0.86, 95% CISD: [0.51–1.45], PSD=0.56; OR 0.62, 95% CIPD: [0.35–1.11], PPD=0.11; OR 0.53, 95% CISAE: [0.14–1.92], PSAE=0.33).Conclusion: This study showed that HAIC was associated with better efficacy than sorafenib in terms of OSR and tumor response. Therefore, HAIC can be considered as an alternative treatment option for patients with HCCs of BCLC stage C. [ABSTRACT FROM AUTHOR]

Background: In patients with advanced hepatocellular carcinoma (HCC), evidence is unclear as to whether hepatic arterial infusion chemotherapy (HAIC) or sorafenib is superior. We performed a prospective, open-label, non-comparative phase II study to assess survival with HAIC or HAIC converted to sorafenib.Methods: Fifty-five patients were prospectively enrolled. Patients received HAIC as a second course if they had complete response, partial response, or stable disease (SD) with an alpha fetoprotein (AFP) ratio < 1 or a des-γ-carboxy prothrombin (DCP) ratio < 1. Patients were switched to sorafenib if they had SD with an AFP ratio > 1 and a DCP ratio > 1 or disease progression. The primary endpoint was the 1-year survival rate. Secondary endpoints were the 2-year survival rate, HAIC response, survival rate among HAIC responders, progression-free survival, and adverse events.Results: Of the 55 patients in the intent-to-treat population, the 1-year and 2-year survival rates were 64.0 and 48.3%, respectively. After the first course of HAIC, one (1.8%) patient showed complete response, 13 (23.6%) showed partial response, 30 (54.5%) had SD, and 10 (18.1%) patients had progressive disease. Twenty-three patients (41.8%) had SD with AFP ratios < 1 or DCP ratios < 1, and 7 (12.7%) had SD with AFP ratios > 1 and DCP ratios > 1. Thirty-seven patients (68.5%) were responders and 17 (30.9%) were non-responders to HAIC. In responders, the 1-year and 2-year survival rates were 78 and 62%, respectively.Conclusion: Given the results of this study, this protocol deserves consideration for patients with advanced HCC. This trial was registered prospectively from December 12. 2012 to September 1. 2016. [ABSTRACT FROM AUTHOR]

Background: The most frequent pattern of recurrence is remnant liver after hepatectomy for gastric cancer liver metastases (GLM). The evidence of adjuvant hepatic artery infusion chemotherapy (HAIC) after hepatectomy for GLM is lacking. The aim of this study was to evaluate the efficacy of adjuvant HAIC after hemihepatectomy for GLM.Methods: Between 2001 and 2012, 14 patients who underwent hemihepatectomy for GLM were included in this study. Adjuvant HAIC to the remnant hemiliver was the FEM regimen (333 mg/m2 5-fluorouracil each week, 30 mg/m2 epirubicin once every 4 weeks, and 2.7 mg/m2 mitomycin-C once every 2 weeks) and was administered for 6 months after hemihepatectomy. Clinicopathological prognostic factors for survival were analyzed using a prospectively collected database.Results: Nine patients had solitary GLM, and 5 patients had multiple GLM before surgery. The median period from hemihepatectomy to HAIC was 30 days. The 6-month HAIC completion rate was 79% (n = 11/14). Reasons of HAIC failure included liver dysfunction (n = 1), catheter infection (n = 1), and development of multiple recurrence (n = 1). The median follow-up was 29 (range 8-166) months. Recurrences were detected in 8 patients (57%). The site of recurrences included lung (n = 1), lymph nodes (n = 1), peritoneal dissemination (n = 1), brain (n = 1), pleural (n = 1), and multiple sites (n = 3). The overall 5-year survival rate was 43%. The pathological T4 classification and the preoperative CEA ≥5 ng/mL were significant prognostic factors for overall survival.Conclusions: Adjuvant HAIC after hemihepatectomy for GLM prevents remnant liver recurrence and may contribute to long-term survival.

Purpose: To compare the complication rates associated with hepatic arterial infusion chemotherapy (HAIC) for unresectable hepatocellular carcinoma (HCC) using two different catheter tip locations, the right/left hepatic artery (group 1) and the gastroduodenal artery (group 2). Methods: Between April 2001 and March 2015, 88 patients (group 1, n = 36; group 2, n = 52) with unresectable HCC, underwent HAIC via a transfemorally placed infusion catheter. The incidence of complications related to catheter placement (including hepatic arterial occlusion, catheter dislocation, non-target embolization and port-catheter system infection) as well as catheter patency and patient survival were evaluated. Results: The technical success rate was 100%. The overall complication rate was 17% (15/88 patients). The specific complications were as follows: hepatic artery occlusion, n = 1 (group 2, n = 1), gastroduodenal ulcer, n = 6 (group 1, n = 2; group 2, n = 4); catheter dislocation, n = 1 (group 2, n = 1); port-catheter system infection, n = 3 (group 2, n = 3); and bleeding at the puncture site, n = 4 (group 1, n = 1; group 2, n = 3). Conclusions: The complication rates in groups 1 and 2 did not differ to a statistically significant extent. [ABSTRACT FROM AUTHOR]

Methods: This was a single-arm historical cohort study of ESCC patients with synchronous or heterochronous LM between December 2014 and July 2021 at the Department of Gastrointestinal Oncology. The patients were treated with HAIC for LM, and regular image assessments were performed according to the judgment of the interventional physician. Liver progression-free survival (PFS), liver objective response rate (ORR), liver disease control rate (DCR), overall survival (OS), adverse events (AEs), treatment information, and basic characteristics were observed retrospectively., Results: Overall, a total of 33 patients were enrolled in this study. All included patients received catheterized HAIC therapy, with a median of three (ranging from 2 to 6) sessions. The treatment response of liver metastatic lesions included partial response (PR) in 16 (48.5%) patients, stable disease (SD) in 15 (45.5%) patients, and progressive disease (PD) in two (6.1%) patients, for an ORR of 48.5% and a DCR of 93.9%. The median liver PFS was 4.8 months (95% confidence interval (CI): 3.0-6.6 months), and the median OS was 6.4 months (95% CI: 6.1-6.6 months). Patients who achieved PR at the liver metastasis site after HAIC were more likely to have a longer OS than those who achieved SD or PD. Grade 3 AEs occurred in 12 patients. The most common grade 3 AE was nausea, occurring in 10 (30.0%) patients, followed by abdominal pain in three (9.1%) patients. Only one patient showed grade 3 elevation of alanine aminotransferase (ALT)/aspartate aminotransferase (AST), and one patient suffered from grade 3 embolism syndrome AEs. Grade 4 adverse events, followed by abdominal pain, occurred in one patient., Conclusion: Hepatic arterial infusion chemotherapy might be an option as a regional therapy for ESCC patients with LM, as it is acceptable and tolerable., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Dong, Cao and Lu.)

Background and Aim It has been reported about poor prognosis in patients with advanced hepatocellular carcinoma ( HCC) refractory to hepatic arterial infusion chemotherapy ( HAIC). We assessed the survival benefits of sorafenib therapy for advanced HCC in HAIC refractory patients. Methods The study subjects were 191 patients with advanced HCC who had been treated with HAIC. Sorafenib was used in 27 patients who finally failed to respond to HAIC ( HAIC/sorafenib group). Clinical outcome was compared between HAIC/sorafenib and HAIC alone groups. Results There were no significant differences in clinical characteristics and response rate of HAIC between the two groups (response rate: 25.9%, HAIC/sorafenib group; 30.4%, HAIC alone group). The median survival time ( MST) for all patients was 11.0 months. The survival rate was significantly higher in the HAIC/sorafenib group than HAIC alone group ( MST 22.2 vs 8.7 months, P = 0.017). From administration sorafenib, the disease control rate was 51.8% with MST of 10.4 months. Among HAIC non-responders, the survival rate was significantly higher in the HAIC/sorafenib group than HAIC alone group. Multivariate analysis identified additional therapy with sorafenib as significant and independent determinant of overall survival in all patients and HAIC non-responders. Conclusion Additional therapy with sorafenib could probably improve the prognosis of HAIC refractory patients. [ABSTRACT FROM AUTHOR]

This paper is concerned with high-dimensional modifications of Akaike information criterion (AIC) for selection of variables in discriminant analysis. The AIC has been proposed as an asymptotically unbiased estimator of the risk function of the candidate model when the dimension is fixed and the sample size tends to infinity. On the other hand, Fujikoshi () attempted to modify the AIC in two-group discriminant analysis when the dimension and the sample size tend to infinity. Such an estimator is called high-dimensional AIC, which is denoted by HAIC. However, its modification was obtained under a restrictive assumption, and furthermore, it was difficult to extend the method to multiple-group case. In this paper, by a new approach we propose HAIC which is an asymptotically unbiased estimator of the risk function in multiple-group discriminant analysis when both the dimension and the sample size tend to infinity, for a general class of candidate models. By simulation experiments it is shown that HAIC is more useful than other AIC type of criteria. [ABSTRACT FROM AUTHOR]
