Analysis of the safety and effectiveness of TACE combined with targeted immunotherapy in the treatment of intermediate and advanced hepatocellular carcinoma. Med Oncol 2023; 40:251. [PMID: 37498394 DOI: 10.1007/s12032-023-02082-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Accepted: 06/05/2023] [Indexed: 07/28/2023]
Abstract
To evaluate the effectiveness and safety of transarterial chemoembolization (TACE) combined with immune and targeted therapy in unresectable hepatocellular carcinoma (HCC). Prospective analysis of 23 patients with intermediate or advanced primary HCC treated at the Department of Hepatic Surgery, The First Affiliated Hospital of the University of Science and Technology of China from July 2019, including 11 cases treated with TACE alone and 12 cases treated with TACE combined with targeted therapy. The basal indexes of patients in the two groups were compared, and the response during treatment was observed; regular follow-up was performed to assess the efficacy of tumor treatment. Compared with TACE treatment alone, the objective response rate (ORR) was significantly higher in the TACE combined with targeted treatment group (50.0% vs 36.4%), with a higher success rate of surgical conversion (33.3% vs 18.2%) and a significantly longer progression-free survival (PFS) (20.5 ± 2.9 months vs 11.6 ± 2.9 months). Multifactorial regression analysis identified tumor vascular invasion as an independent prognostic factor affecting HCC. No patient experienced catheter retention-related complications during treatment, and there were no intolerable adverse effects. TACE combined with targeted treatment for intermediate to advanced unresectable HCC was effective, with good tumor responsiveness, high surgical conversion rate, and safe and controllable adverse reactions during treatment.

Safety, efficacy, and survival of drug-eluting beads- transarterial chemoembolization vs. conventional-transarterial chemoembolization in advanced HCC patients with main portal vein tumor thrombus. Cancer Imaging 2023; 23:70. [PMID: 37481660 PMCID: PMC10362718 DOI: 10.1186/s40644-023-00581-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Accepted: 06/01/2023] [Indexed: 07/24/2023] Open
Abstract
OBJECTIVES To compare the efficacy, overall survival (OS) and safety of drug-eluting beads-TACE (DEB-TACE) and C-TACE as initial treatment in advanced hepatocellular carcinoma (HCC) patients with main portal vein tumor thrombus (mPVTT). METHODS The medical records of consecutive advanced HCC patients with mPVTT who underwent initial DEB-TACE or C-TACE from September 2015 to October 2021 were retrospectively evaluated. Treatment crossover was allowed in this retrospective research. The adverse events, disease control rate (DCR), time to tumor progression (TTP) and OS of patients who underwent DEB-TACE were compared with those of patients who underwent C-TACE. RESULTS Eighty-three patients were included: 42 patients in DEB-TACE group and 41 patients in C-TACE group. DEB-TACE could be safely performed in HCC patients with mPVTT, and they gained a better DCR than those submitted to the C-TACE (76.2% vs. 53.7%, P = 0.031), which might have resulted in longer TTP (median TTP: 9.0 months vs. 3.0 months, P < 0.001). Furthermore, DEB-TACE showed significant OS benefits compared with C-TACE (median OS: 12.0 months vs. 5.0 months, P < 0.001). DEB-TACE, absence of arterioportal shunts (APS), leisons with capsular non-infiltration were found to be independent prognostic factors for better OS. Furthermore, subgroup analysis proved that patients with good DCR gained longer OS in DEB-TACE group. CONCLUSIONS DEB-TACE could be safely performed and improve the DCR of HCC patients with mPVTT, which resulting in longer TTP and OS, compared with C-TACE.

World J Surg Oncol 2023; 21:208. [PMID: 37475030 PMCID: PMC10360255 DOI: 10.1186/s12957-023-03098-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2023] [Accepted: 07/12/2023] [Indexed: 07/22/2023] Open
Abstract
BACKGROUND Transarterial therapies, including transarterial chemoembolization (TACE), hepatic arterial infusion chemotherapy (HAIC), and selective internal radiation therapy, combined with first-line tyrosine kinase inhibitors (TKIs) are considered the standard therapy for unresectable hepatocellular carcinoma. However, inconsistent results have been reported in various studies assessing different combinations of targeted agents. METHODS A network meta-analysis (NMA) was performed by including 23 randomized controlled trials (RCTs) with 6175 patients to investigate the efficiency of transarterial therapies in combination with different TKIs. Outcomes of interest included overall survival (OS), progression-free survival (PFS), time to progression (TTP), and tumor objective response rate (ORR). A random-effects consistency model was used in this Bayesian NMA. Hazard ratio and odd risks with a 95% credible interval were calculated and agents were ranked based on ranking probability. RESULTS HAIC showed maximal OS and TTP and TACE plus lenvatinib showed maximal PFS, ORR, and disease control rate (DCR). HAIC and TACE plus lenvatinib were ranked highest based on their respective parameters, which were OS for HAIC and PFS, ORR, and DCR for TACE plus lenvatinib. CONCLUSION HAIC and TACE plus lenvatinib were relatively better choice for unresectable hepatocellular carcinoma. However, owing to the lack of statistically significant OS benefits among most agents, other agents should be considered as potential alternatives for unresectable hepatocellular carcinoma.

Abstract
BACKGROUND Transarterial chemoembolization (TACE) is widely performed for intermediate-stage or unresectable hepatocellular carcinoma (HCC), but approximately half of patients do not respond to TACE treatment. We describe a case of rapidly progressing of HCC after TACE and provide a possible hypothesis for this condition. The finding may contribute to identifying patients who obtain less benefit from TACE, thus avoiding the unnecessary waste of medical resources and treatment during the golden hour window.
CASE SUMMARY A 61-year-old woman had been diagnosed with chronic hepatitis B infection and HCC at Barcelona Clinic Liver Cancer stage B, which had been treated by segmental hepatectomy 14 mo ago. The tumor recurred in the two months after surgery. She received an initial TACE and then underwent systemic therapy with lenvatinib 8 mg daily due to an increased level of alpha-fetoprotein (AFP) after the first TACE. However, the tumor continued to progress with an increased level of AFP, and she underwent a second TACE, after which the tumor volume did not obviously decrease on the contrast-enhanced computed tomography image. One month later, she had a third TACE to control the residual HCC tumors. Two weeks after that, the HCC had increased dramatically with tea-colored urine and yellowish skin turgor. Eventually, the patient refused further treatment and went into hospice care.
CONCLUSION Intense hypoxia induced by TACE can trigger rapid disease progression in infiltrative HCC patients with a large tumor burden

Abstract
OBJECTIVE Local combined systemic therapy has been an important method for the treatment of unresectable hepatocellular carcinoma (HCC).The purpose of this study was to compare the effectiveness and safety of transarterial chemoembolization (TACE) plus Sorafenib versus TACE plus Apatinib for treating patients with unresectable HCC. METHODS The clinical data of patients with unresectable HCC who were treated with TACE plus Sorafenib or TACE plus Apatinib at 5 Chinese medical centers between January 2016 and December 2020 were retrospectively analyzed. Propensity score matching (PSM) was applied to reduce the bias from confounding factors. RESULTS A total of 380 patients were enrolled, of whom 129 cases were treated with TACE plus Sorafenib and 251 cases with TACE plus Apatinib. After the 1:1 PSM, 116 pairs of patients were involved in this study. The results showed that the PFS and OS in the TACE-Sorafenib group were significantly longer than those in the TACE-Apatinib group (PFS: 16.79 ± 6.45 vs. 14.76 ± 6.98 months, P = 0.049; OS: 20.66 ± 6.98 vs. 17.69 ± 6.72 months, P = 0.013). However, the ORR in the TACE-Apatinib group was markedly higher than that in the TACE-Sorafenib group (70.69% vs. 56.03%, P = 0.021). There were more patients with adverse events (AEs) in the TACE-Apatinib group than those in the TACE-Sorafenib group before dose adjustment (87 vs. 63, P = 0.001); however, the number of patients who suffered from AEs was not significantly different between the two groups after the dose adjustment (62 vs. 55, P = 0.148). No treatment-related death was found in the two groups. Subgroup analysis revealed that patients with unresectable HCC could better benefit from regular doses than reduced doses (Sorafenib, 22.59 vs. 18.02, P < 0.001; Apatinib, 19.75 vs. 16.86, P = 0.005). CONCLUSION TACE plus either Sorafenib or Apatinib could effectively treat patients with unresectable HCC, the safety of TACE plus Sorafenib was better. and the ORR of TACE plus Apatinib was higher.

Abstract
BACKGROUND The ALBI-TAE model was recently proposed as a scoring system to select suitable patients with intermediate-stage hepatocellular carcinoma (HCC) for transarterial chemoembolization (TACE). However, this scoring system has not been externally validated. Therefore, we validated this score and compared it with six scoring systems in terms of prognostication. METHODS We retrospectively enrolled 480 patients with intermediate-stage HCC who underwent TACE at a tertiary care center between January 2008 and December 2019. Seven scores, which included the ALBI-TAE model, Bolondi's subclassification, HAP score, mHAP-II score, tumor burden score, six-and-twelve score, and seven-eleven criteria, were calculated and a head-to-head comparison was made in terms of prognostic power using Harrell's C-index. Prognostic factors associated with survival were analyzed. RESULTS ALBI-TAE group A had the longest median overall survival (OS) of 40.80 months, followed by ALBI-TAE groups B, C, and D of 20.14 months, 10.58 months, and 7.54 months, respectively, with significant differences (P < 0.001). Among the seven scores, the ALBI-TAE model had the best predictive performance (Harrell's C-index 0.633) in differentiating OS in intermediate-stage HCC patients. Moreover, the ALBI-TAE model was identified as an independent prognostic factor for survival outcome in multivariate analysis. CONCLUSION Our study confirmed the value of the ALBI-TAE model with excellent prognostic discriminatory power in intermediate-stage HCC patients. The ALBI-TAE model is a simple and valuable predictive tool to identify patients with good prognosis who can get the most benefit from TACE.

A Novel Nomogram for Predicting the Overall Survival in Patients with Unresectable HCC after TACE plus Hepatic Arterial Infusion Chemotherapy. Transl Oncol 2023; 34:101705. [PMID: 37257332 DOI: 10.1016/j.tranon.2023.101705] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Revised: 05/14/2023] [Accepted: 05/23/2023] [Indexed: 06/02/2023] Open
Abstract
BACKGROUND AND AIM Transarterial chemoembolization combined with hepatic arterial infusion chemotherapy (TACE-HAIC) has shown encouraging efficacy in the treatment of unresectable hepatocellular carcinoma (HCC). We aimed to develop a novel nomogram to predict overall survival (OS) of patients with unresectable HCC treated with TACE-HAIC. METHODS A total of 591 patients with unresectable HCC treated with TACE-HAIC between May 2009 and September 2020 were enrolled. These patients were randomly divided into training and validation cohorts. The independent prognostic factors were identified with Cox proportional hazards model. The model's discriminative ability and accuracy were validated using concordance index (C-index), calibration plots, the area under the time-dependent receiver operating characteristic curve (AUC) and decision curve analyses (DCAs). RESULTS The median OS was 15.6 months. A nomogram was established based on these factors, including tumor size, vein invasion, extrahepatic metastasis, tumor number, alpha fetoprotein (AFP), and albumin-bilirubin (ALBI), to predict OS for patients with unresectable HCC treated with TACE-HAIC. The C-index of the nomogram were 0.717 in the training cohort and 0.724 in validation cohort. The calibration plots demonstrated good agreement between the predicted outcomes and the actual observations. The AUC values were better than those of three conventional staging systems. The results of DCA indicated that the nomogram may have clinical usefulness. The patients in the low-risk group had a longer OS than those in intermediate-risk and high-risk groups (P<0.001). CONCLUSION A prognostic nomogram was developed and validated to assist clinicians in accurately predicting the OS of patients with unresectable HCC after TACE-HAIC.

Abstract
BACKGROUND The efficacy of conversion therapy for patients with unresectable hepatocellular carcinoma (HCC) is a common clinical concern.
AIM To analyse the prognostic factors of overall survival (OS) in patients with unresectable HCC who received conversion therapy.
METHODS One hundred and fifty patients who met the inclusion criteria were enrolled and divided into a training cohort (n = 120) and a validation cohort (n = 30). Using the independent risk factors in the training cohort, a nomogram model was constructed to predict OS for patients treated with transarterial chemoembolization following hepatic resection. The nomogram was internally validated with the bootstrapping method. The predictive performance of nomogram was assessed by Harrell’s concordance index (C-index), calibration plot and time-dependent receiver operating characteristic curves and compared with six other conventional HCC staging systems.
RESULTS Multivariate Cox analysis identified that albumin, blood urea nitrogen, gamma-glutamyl transpeptidase to platelet ratio, platelet to lymphocyte ratio, macrovascular invasion and tumour number were the six independent prognostic factors correlated with OS in nomogram model. The C-index in the training cohort and validation cohort were 0.752 and 0.807 for predicting OS, which were higher than those of the six conventional HCC staging systems (0.563 to 0.715 for the training cohort and 0.458 to 0.571 for the validation cohort). The calibration plots showed good consistency between the nomogram prediction of OS and the actual observations of OS. Decision curve analyses indicated satisfactory clinical utility. With a total nomogram score of 196, patients were accurately classified into low-risk and high-risk groups. Furthermore, we have deployed the model into online calculators that can be accessed for free at https://ctmodelforunresectablehcc.shinyapps.io/DynNomapp/.
CONCLUSION The nomogram achieved optimal individualized prognostication of OS in HCC patients who received conversion therapy, which could be a useful clinical tool to help guide postoperative personalized interventions and prognosis judgement.

Abstract
PURPOSE In early-stage hepatocellular carcinoma (HCC) patients merely fit for surgery, transarterial chemoembolization (TACE) achieve low long-term disease control. We evaluated the efficacy and safety of its combination with moderately hypofractionated radiotherapy (hRT) using RTF3 regimen. MATERIAL AND METHODS Between 2006 and 2016, 61 consecutive patients treated in our single expert center for a Barcelona Clinic Liver Cancer (BCLC) A HCC by TACE followed by hRT 3Gy/fraction were retrospectively included. RESULTS Sixty of the 61 included presented Child-Pugh A cirrhosis (A5, n=41, 67.2%; A6: n=19, 31.1%). Fourteen patients (22.9%) were already treated for a HCC, mainly by radiofrequency (n=12). All patient received a TACE followed by 3Gy per fraction hRT. Mean radiation dose was 54Gy (range: 48-60). After a median follow-up of 118 months, median time-to-progression, progression-free survival (PFS) and overall survival (OS) was 21.3, 18.1, and 31.5 months, respectively. In univariate analysis, PFS was related to dose > 54Gy (HR: 2, P=0.036), and OS was correlated to Child-Pugh A6 or B7 (HR: 1.93, P=0.03) and overall hRT time (HR: 1.06, P=0.015). At progression, orthotopic liver transplantation was performed in 8 patients (13.1%). Severe symptomatic adverse events occurred in 12 patients (19.7%), mainly ascites (n=7). CONCLUSION In BCLC-A Child-Pugh A HCC patients ineligible to surgery or thermoablation, TACE-hRT is a safe and effective treatment. Prospective studies are needed to compare this association with radioembolization, TACE-stereotactic radiotherapy, and systemic treatments combinations.

Abstract
OBJECTIVE Hepatocellular carcinoma (HCC) is a highly prevalent form of liver cancer diagnosed annually in 600,000 people worldwide. A common treatment is transarterial chemoembolization (TACE), which interrupts the blood supply of oxygen and nutrients to the tumor mass. The need for repeat TACE treatments may be assessed in the weeks after therapy with contrast-enhanced ultrasound (CEUS) imaging. Although the spatial resolution of traditional CEUS has been restricted by the diffraction limit of ultrasound (US), this physical barrier has been overcome by a recent innovation known as super-resolution US (SRUS) imaging. In short, SRUS enhances the visible details of smaller microvascular structures on the 10 to 100 µm scale, which unlocks a host of new clinical opportunities for US. METHODS In this study, a rat model of orthotopic HCC is introduced and TACE treatment response (to a doxorubicin-lipiodol emulsion) is assessed using longitudinal SRUS and magnetic resonance imaging (MRI) performed at 0, 7 and 14 d. Animals were euthanized at 14 d for histological analysis of excised tumor tissue and determination of TACE response, that is, control, partial response or complete response. CEUS imaging was performed using a pre-clinical US system (Vevo 3100, FUJIFILM VisualSonics Inc.) equipped with an MX201 linear array transducer. After administration of a microbubble contrast agent (Definity, Lantheus Medical Imaging), a series of CEUS images were collected at each tissue cross-section as the transducer was mechanically stepped at 100 μm increments. SRUS images were formed at each spatial position, and a microvascular density metric was calculated. Microscale computed tomography (microCT, OI/CT, MILabs) was used to confirm TACE procedure success, and tumor size was monitored using a small animal MRI system (BioSpec 3T, Bruker Corp.). RESULTS Although there were no differences at baseline (p > 0.15), both microvascular density levels and tumor size measures from the complete responder cases at 14 d were considerably lower and smaller, respectively, than those in the partial responder or control group animals. Histological analysis revealed tumor-to-necrosis levels of 8.4%, 51.1% and 100%, for the control, partial responder and complete responder groups, respectively (p < 0.005). CONCLUSION SRUS imaging is a promising modality for assessing early changes in microvascular networks in response to tissue perfusion-altering interventions such as TACE treatment of HCC.

Abstract
INTRODUCTION Transarterial hepatic chemoembolization (TACE) has been used to treat unresectable hepatocellular carcinoma and has gained widespread acceptance as a treatment for both primary and secondary hepatic malignancies. CASE REPORT We report a case of 78-year-old male patient with chronic hepatitis B, diagnosed with HCC. He underwent the second TACE, and right after the procedure, the patient abruptly developed bilateral lower extremities motor weakness and sensory impairment below the T10 dermatome. Spinal magnetic resonance imaging showed T2-weighted scans showed increased intramedullary signal strength at the T1-T12 level. The patient received supportive care, ongoing rehabilitation, and steroid pulse therapy. The motor strength remained unchanged, but the sensory deficiencies practically disappeared. CLINICAL DISCUSSION The hepatic artery injury or decreased flow at the prior TACE site, which causes collateral recruitment, can explain why spinal cord injury following TACE typically happens after the second or third session. It can occasionally result from accidental embolized spinal branches originating from intercostal or lumbar collateral arteries. In our case, we hypothesize the embolism caused the infarction to the spinal cord travel through the connection between the lateral branches of the right inferior phrenic artery and the intercostal arteries, which supply the spinal cord through the anterior spinal artery. CONCLUSIONS TACE in rare case can have severe complications. A tailored therapeutic strategy, including consideration of a shunt and selection of the vessels utilized for the Lipiodol infusion prior to TACE, is crucial to achieving an optimal end outcome to avert these significant consequences.

Abstract
PURPOSE To compare the clinical benefit and tolerability of triple therapy of lenvatinib, programmed death 1 (PD-1) inhibitor, and transarterial chemoembolization (TACE) versus dual therapy of lenvatinib and PD-1 inhibitor in unresectable hepatocellular carcinoma (HCC) patients. METHODS Between October 2018 and September 2021, patients with unresectable HCC who received triple therapy of lenvatinib, PD-1 inhibitor, and TACE or dual therapy of lenvatinib and PD-1 inhibitor participated in this study. The efficacy was evaluated by survival and therapeutic response, and the tolerability was evaluated by the frequency and severity of key adverse events (AEs). RESULTS In total, 118 eligible patients with unresectable HCC who received combination therapy were included in this study. Among them, 60 patients received triple therapy of lenvatinib, PD-1 inhibitor, and TACE (L-P-T group), and 58 eligible patients received dual therapy of lenvatinib and PD-1 inhibitor (L-P group). Patients who received triple therapy had better overall survival (OS) [median, 29.0 vs. 17.8 months, p < 0.01] and progression-free survival (PFS) [median, 16.2 vs. 10.2 months, p < 0.01] than those who received dual therapy. The objective response rate (76.7 vs. 44.9%, p < 0.01) and disease control rate (96.7 vs. 75.9%, p < 0.01) in the L-P-T group were higher than in the L-P group, respectively. Multivariate analyses revealed that the treatment option and BCLC stage were independent prognostic factors for OS, while treatment option and tumor number were independent prognostic factors for PFS. The incidence and severity of AEs in the L-P-T group were comparable to those in the L-P group (any grade, 95.0 vs. 94.8%, p = 1.00; grade ≥ 3, 30.0 vs. 27.6%, p = 0.93). CONCLUSION Triple therapy of lenvatinib, PD-1 inhibitor, and TACE may achieve more favorable survival benefits than dual therapy of lenvatinib and PD-1 inhibitor in unresectable HCC patients with manageable safety profiles.

Identifying optimal candidates for post-TIPS patients with HCC undergoing TACE: a multicenter observational study. Eur Radiol 2023; 33:2809-2820. [PMID: 36562786 PMCID: PMC10017639 DOI: 10.1007/s00330-022-09249-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Revised: 09/19/2022] [Accepted: 10/19/2022] [Indexed: 12/24/2022]
Abstract
OBJECTIVE To develop a prognostic model for post-transjugular intrahepatic portosystemic shunt (TIPS) patients with hepatocellular carcinoma (HCC) beyond the Milan criteria treated by transarterial chemoembolization (TACE). DESIGN Between January 2013 and January 2020, 512 patients with HCC beyond the Milan criteria who underwent TACE after TIPS were retrospectively recruited from 15 tertiary centers. Patients were randomly sorted into a training set (n = 382) and a validation set (n = 130). Medical data and overall survival were assessed. A prediction model was developed using multivariate Cox regression analyses. Predictive performance and discrimination were evaluated and compared with other prognostic models. RESULTS Vascular invasion, log10(AFP), 1/creatinine, extrahepatic spread, and log10(ALT) were the most significant prognostic factors of survival. These five parameters were included in a new VACEA score. This score was able to stratify patients in the training set into four distinct risk grades whose median overall survival were 25.2, 15.1, 8.9, and 6.2 months, respectively. The 6-month, 1-year, 2-year, and 3-year AUROC values and C-index of the VACEA model were 0.819, 0.806, 0.779, 0.825, and 0.735, respectively, and higher than those of other seven currently available models in both the training and validation sets, as well as in different subgroups. CONCLUSION The VACEA score could stratify post-TIPS patients with HCC beyond the Milan criteria treated by TACE and help to identify candidates who benefit from this treatment. KEY POINTS • Vascular invasion, AFP, creatinine, extrahepatic spread, and ALT were independent significant prognostic factors of survival for HCC patients who underwent TACE after TIPS. • Our new model, named VACEA score, can accurately predict prognosis at the individual level and stratify patients into four distinct risk grades. • The VACEA model showed better prognostic discrimination and calibration than other current TACE-/TIPS-specific models Graphical abstract.

Abstract
Transarterial chemoembolization (TACE) is an important approach for the treatment of unresectable hepatocellular carcinoma (HCC). However, the lactic acid-induced acidic tumor microenvironment (TME) may reduce the therapeutic outcome of TACE. Herein, monodispersed gelatin microspheres loaded with calcium carbonate nanoparticles (CaNPs@Gel-MS) as novel embolic agents were prepared by a simplified microfluidic device. It was found that the particle size and homogeneity of as-prepared CaNPs@Gel-MS were strongly dependent on the flow rates of continuous and dispersed phases, and the inner diameter of syringe needle. The introduction of CaNPs provided the gelatin microspheres with an enhanced ability to encapsulate the chemotherapeutic drug of DOX, as well as a pH-responsive sustained drug release behavior. In vitro results revealed that CaNPs@Gel-MS could largely increase the cellular uptake and chemotoxicity of DOX by neutralizing the lactic acid in the culture medium. In addition, CaNPs@Gel-MS exhibited an excellent and persistent embolic efficiency in a rabbit renal model. Finally, we found that TACE treatment with DOX-loaded CaNPs@Gel-MS (DOX/CaNPs@Gel-MS) had a much stronger ability to inhibit tumor growth than the DOX-loaded gelatin microspheres without CaNPs (DOX@Gel-MS). Overall, CaNPs@Gel-MS could be a promising embolic microsphere that can significantly improve anti-HCC ability by reversing lactic acid-induced chemotherapy resistance during TACE treatment.

Abstract
BACKGROUND Programmed death receptor-1 (PD-1) inhibitors have been approved as second-line treatment regimen in hepatocellular carcinoma (HCC), but it is still worth studying whether patients can benefit from PD-1 inhibitors as first-line drugs combined with targeted drugs and locoregional therapy.
AIM To estimate the clinical outcome of transarterial chemoembolization (TACE) and lenvatinib plus PD-1 inhibitors for patients with unresectable HCC (uHCC).
METHODS We carried out retrospective research of 65 patients with uHCC who were treated at Peking Union Medical College Hospital from September 2017 to February 2022. 45 patients received the PD-1 inhibitors, lenvatinib, TACE (PD-1-Lenv-T) therapy, and 20 received the lenvatinib, TACE (Lenv-T) therapy. In terms of the dose of lenvatinib, 8 mg was given orally for patients weighing less than 60 kg and 12 mg for those weighing more than 60 kg. Of the patients in the PD-1 inhibitor combination group, 15 received Toripalimab, 14 received Toripalimab, 14 received Camrelizumab, 4 received Pembrolizumab, 9 received Sintilimab, and 2 received Nivolumab, 1 with Tislelizumab. According to the investigators’ assessment, TACE was performed every 4-6 wk when the patient had good hepatic function (Child-Pugh class A or B) until disease progression occurred. We evaluated the efficacy by the modified Response Evaluation Criteria in Solid Tumors (mRECIST criteria). We accessd the safety by the National Cancer Institute Common Terminology Criteria for Adverse Events, v 5.0. The key adverse events (AEs) after the initiation of combination therapy were observed.
RESULTS Patients with uHCC who received PD-1-Lenv-T therapy (n = 45) had a clearly longer overall survival than those who underwent Lenv-T therapy (n = 20, 26.8 vs 14.0 mo; P = 0.027). The median progression-free survival time between the two treatment regimens was also measured {11.7 mo [95% confidence interval (CI): 7.7-15.7] in the PD-1-Lenv-T group vs 8.5 mo (95%CI: 3.0-13.9) in the Lenv-T group (P = 0.028)}. The objective response rates of the PD-1-Lenv-T group and Lenv-T group were 44.4% and 20% (P = 0.059) according to the mRECIST criteria, meanwhile the disease control rates were 93.3% and 64.0% (P = 0.003), respectively. The type and frequency of AEs showed little distinction between patients received the two treatment regimens.
CONCLUSION Our results suggest that the early combination of PD-1 inhibitors has manageable toxicity and hopeful efficacy in patients with uHCC.

Abstract
BACKGROUND Using texture features derived from contrast-enhanced computed tomography (CT) combined with general imaging features as well as clinical information to predict treatment response and survival in patients with hepatocellular carcinoma (HCC) who received transarterial chemoembolization (TACE) treatment. METHODS From January 2014 to November 2022, 289 patients with HCC who underwent TACE were retrospectively reviewed. Their clinical information was documented. Their treatment-naïve contrast-enhanced CTs were retrieved and reviewed by two independent radiologists. Four general imaging features were evaluated. Texture features were extracted based on the regions of interest (ROIs) drawn on the slice with the largest axial diameter of all lesions using Pyradiomics v3.0.1. After excluding features with low reproducibility and low predictive value, the remaining features were selected for further analyses. The data were randomly divided in a ratio of 8:2 for model training and testing. Random forest classifiers were built to predict patient response to TACE treatment. Random survival forest models were constructed to predict overall survival (OS) and progress-free survival (PFS). RESULTS We retrospectively evaluated 289 patients (55.4 ± 12.4 years old) with HCC treated with TACE. Twenty features, including 2 clinical features (ALT and AFP levels), 1 general imaging feature (presence or absence of portal vein thrombus) and 17 texture features, were included in model construction. The random forest classifier achieved an area under the curve (AUC) of 0.947 with an accuracy of 89.5% for predicting treatment response. The random survival forest showed good predictive performance with out-of-bag error rate of 0.347 (0.374) and a continuous ranked probability score (CRPS) of 0.170 (0.067) for the prediction of OS (PFS). CONCLUSIONS Random forest algorithm based on texture features combined with general imaging features and clinical information is a robust method for predicting prognosis in patients with HCC treated with TACE, which may help avoid additional examinations and assist in treatment planning.

Abstract
BACKGROUND Neuroendocrine tumors (NETs) belong to a rare family of tumors whose incidence has increased significantly over the past 50 years. PURPOSE To evaluate the prognostic value of volumetric arterial enhancement (VAE) on baseline magnetic resonance imaging (MRI) for patients with neuroendocrine liver metastasis (NELM) treated using transarterial chemoembolization (TACE). MATERIAL AND METHODS Between October 2012 and December 2018, VAE in 37 patients was measured with a semi-automatic volume of Interest (VOI) on subtracted T1 sequence in the arterial phase. Patients underwent 1-3 sectoral lipiodol TACE. Radiologic response using modified Response Evaluation Criteria in Solid Tumors (mRECIST) at the treatment cycle end and progression free survival were determined. RESULTS Median age was 68.0 (60.0; 73.0). Twenty-three patients (62%) had a partial response, 10 (27%) had stable disease, four (11%) had progressive disease. VAE was a significant (P<0.05) predictor of radiologic response. Median progression free survival was 13 months (IC 95: 8; 16). In univariate analysis, significant predictors of local progression were alkaline phosphatase (AP) (P=0.035), Ki-67 index (P=0.014), and VAE (P<0.01). VAE over 500ms and Ki-67 index over 3%were risk factors of progression (P=<0.01) in multivariate analysis. CONCLUSION VAE before TACE could be predictive of radiologic response and could be related to oncologic outcomes in patients with NELM.

Abstract
INTRODUCTION AND IMPORTANCE Transarterial chemoembolization (TACE) is widely employed to control acute bleeding in ruptured hepatocellular carcinoma (rHCC). Ischemia leading to perforation of the gastrointestinal tract (GIT) after TACE is a rare complication. We report a patient who presented with rHCC and who suffered gastric perforation post-TACE. CASE REPORT A 70-year-old woman presented with rHCC. Emergency TACE was undertaken to control bleeding, and was successful. The patient was discharged 5 days post TACE. Two weeks after TACE, she presented with acute abdominal pain. Computed tomography of the abdomen showed perforation at the lesser curvature of the stomach. The angiogram from TACE was reviewed: the small vessels from an accessory branch of the left gastric artery originating from the left hepatic artery that had been embolized were likely responsible for gastric ischemia and subsequent perforation. The patient underwent operation with simple closure and omental patch repair. Postoperative gastric leak was not observed. Unfortunately, the patient died due to severe decompensated liver disease ∼4 weeks after TACE. CLINICAL DISCUSSION Gastrointestinal tract (GIT) perforation after TACE is a rare complication. We suspected that perforation of the lesser curve of the stomach was secondary to ischemia due to non-target embolization to the accessory branch of the left gastric artery from the left hepatic artery, combined with stress and hemodynamic instability from rHCC. CONCLUSIONS rHCC is a life-threatening condition. Variation in vascular structures must be clarified carefully. Significant adverse events in the GIT post-TACE are rare, but high-risk patients must be cautiously monitored.

Abstract
BACKGROUND AND OBJECTIVE Transarterial chemoembolization (TACE) is the gold standard treatment in intermediate hepatocellular carcinoma (HCC), but long-term disease control rates remain low. Herein, we compared results of TACE followed by hypofractionated radiotherapy (TACE-hRT) to surgical resection (SR) in early single or paucinodular intrahepatic HCC. METHODS Between June 2004 and November 2016, data on 160 consecutive patients with Barcelona Clinic Liver Cancer (BCLC) stage A Child-Pugh A HCC treated with SR or TACE-hRT in our expert center were retrospectively reviewed. Time to progression (TTP), progression-free survival (PFS), and overall survival (OS) were evaluated. Clinical outcomes were compared using the stabilized-weights inverse probability of treatment weighting propensity score. RESULTS Ninety-eight patients underwent SR and 62 were treated by TACE-hRT. Median total dose of RT was 54 Gy (interquartile range [IQR] 54-54) in 3‑Gy fractions. Median OS follow-up was 93 months. TTP did not significantly differ between patients following SR and TACE-hRT, with 1‑year rates of 68.2% and 82.6% (p = 0.17), respectively. In contrast, PFS and OS were lower in the TACE-hRT group (p = 0.015 and p = 0.006), with a median OS of 37 vs. 63 months for patients with surgery and TACE-hRT, respectively. In multivariate analysis, a significant negative impact on PFS and OS was seen for age at diagnosis, on TTP for alcohol-related liver disease, and on OS for total number of HCC nodules. Symptomatic grade ≥ 3 adverse events were presented by 42 (42.9%) SR and 19 (30.6%) TACE-hRT patients (p = 0.17). CONCLUSION In patients presenting Child-Pugh A BCLC‑A HCC with high risk for surgical complications, TACE-hRT can be an effective and safe treatment. However, surgical management remains the standard of care whenever possible.

Abstract
OBJECTIVES This study compared the accuracy of predicting transarterial chemoembolization (TACE) outcomes for hepatocellular carcinoma (HCC) patients in the four different classifiers, and comprehensive models were constructed to improve predictive performance. METHODS The subjects recruited for this study were HCC patients who had received TACE treatment from April 2016 to June 2021. All participants underwent enhanced MRI scans before and after intervention, and pertinent clinical information was collected. Registry data for the 144 patients were randomly assigned to training and test datasets. The robustness of the trained models was verified by another independent external validation set of 28 HCC patients. The following classifiers were employed in the radiomics experiment: machine learning classifiers k-nearest neighbor (KNN), support vector machine (SVM), the least absolute shrinkage and selection operator (Lasso), and deep learning classifier deep neural network (DNN). RESULTS DNN and Lasso models were comparable in the training set, while DNN performed better in the test set and the external validation set. The CD model (Clinical & DNN merged model) achieved an AUC of 0.974 (95% CI: 0.951-0.998) in the training set, superior to other models whose AUCs varied from 0.637 to 0.943 (p < 0.05). The CD model generalized well on the test set (AUC = 0.831) and external validation set (AUC = 0.735). CONCLUSIONS DNN model performs better than other classifiers in predicting TACE response. Integrating with clinically significant factors, the CD model may be valuable in pre-treatment counseling of HCC patients who may benefit the most from TACE intervention.

Abstract
PURPOSE To assess the tumor response rates and liver toxicity of boosted-dose transarterial radioembolization (TARE) for treatment of hepatocellular carcinoma (HCC) refractory to previous transarterial embolization (TAE) and/or chemoembolization (TACE). MATERIALS AND METHODS All patients were identified who had HCC treated between 2017 and 2020 that had been refractory to prior TAE or TACE, then treated with boosted-dose segmental or lobar TARE. Tumor response was assessed by multiphasic CT or MRI using localized mRECIST imaging criteria and serological alpha-fetoprotein levels at three and six months after TARE, if available. Liver toxicity was evaluated using serial serological liver function tests, platelet counts, and clinical Child-Pugh and MELD scores. RESULTS Twenty-four patients met inclusion criteria. Mean age was 68.7 years (54-89); 8 were females. Three (12.5%) patients had Barcelona Clinical Liver Cancer stage A, 4 (16.7%) stage B, and 17 (70.8%) stage C disease. Three months after TARE, 52% of patients had a complete response and 33% had a partial response. Mean AFP decreased from 33.2 ng/mL at baseline to 17 ng/mL at 3 months (p = 0.782). The median MELD-Na score increased from 11 at baseline to 16 at 6 months post-TARE (p = 0.044); the mean Child-Pugh score rose from 5 at baseline to 6 at 3 months post-TARE (p < 0.01). CONCLUSION Boosted-dose TARE resulted in statistically significant favorable tumor responses by imaging criteria in 85% of patients previously refractory to TAE or TACE. TARE resulted in transient but acceptable deterioration of liver function and clinical scores.

Abstract
Hepatocellular carcinoma (HCC) has the sixth-highest new incidence and fourth-highest mortality worldwide. Transarterial chemoembolization (TACE) is one of the primary treatment strategies for unresectable HCC. However, the therapeutic effect is still unsatisfactory due to the insufficient distribution of antineoplastic drugs in tumor tissues and the worsened post-embolization tumor microenvironment (TME, e.g., hypoxia and reduced pH). Recently, using nanomaterials as a drug delivery platform for TACE therapy of HCC has been a research hotspot. With the development of nanotechnology, multifunctional nanoplatforms have been developed to embolize the tumor vasculature, creating conditions for improving the distribution and bioavailability of drugs in tumor tissues. Currently, the researchers are focusing on functionalizing nanomaterials to achieve high drug loading efficacy, thorough vascular embolization, tumor targeting, controlled sustained release of drugs, and real-time imaging in the TACE process to facilitate precise embolization and enable therapeutic procedures follow-up imaging of tumor lesions. Herein, we summarized the recent advances and applications of functionalized nanomaterials based on TACE against HCC, believing that developing these functionalized nanoplatforms may be a promising approach for improving the TACE therapeutic effect of HCC.

Abstract
INTRODUCTION This study evaluated the efficacy and safety of transarterial chemoembolization (TACE) combined with lenvatinib plus programmed death (PD)-1 inhibitor (TACE-L-P) versus TACE combined with sorafenib plus PD-1 inhibitor (TACE-S-P) in the treatment of hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT). METHODS The clinical data of patients with HCC and PVTT treated with TACE-L-P or TACE-S-P from January 2018 to March 2022 were collected. The Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 and modified RECIST (mRECIST) standard were used to evaluate the therapeutic effect. The progression-free survival (PFS) and overall survival (OS) of the two groups were compared. Blood samples were collected before and after treatment to detect the changes of biochemical indicators, and the adverse events (AEs) related to treatment were recorded. RESULTS A total of 165 patients were included in the study, including 80 patients receiving TACE-L-P treatment and 85 patients receiving TACE-S-P. Patients in the TACE-L-P group had longer median OS (21.7 months vs. 15.6 months, P = 0.0027), longer median PFS (6.3 months vs. 3.2 months, P < 0.0001), higher objective response rate (41.25% vs. 30.59%, P = 0.008), and higher disease control rate (86.25% vs. 62.35%, P = 0.008) than those in the TACE-S-P group. Multivariate analysis of the TACE-L-P group showed that VP classification of PVTT, Child-Pugh grade, interleukin-17 (IL-17), vascular endothelial growth factor (VEGF), procalcitonin (PCT), and C-reactive protein (CRP) were independent factors significantly affecting patients' OS (P < 0.05). There was no significant difference in the incidence and severity of AEs between the two groups. CONCLUSION TACE-L-P treatment can improve the survival of patients with HCC and PVTT with an acceptable safety, but higher inflammatory indicators will affect the therapeutic effect.
