Objectives: We assessed the diagnostic advantage of dual-energy computed tomography (DECT) over single-energy computed tomography (SECT) to evaluate lipiodol accumulation in target lesions following transcatheter arterial chemoembolization (TACE). Methods: TACE was performed in 10 rabbits in whom the VX2 tumor was implanted in their left liver lobes. The miriplatin-lipiodol mixture was injected into the common hepatic artery. All rabbits were sacrificed 2 days after TACE, and the liver was harvested. CT was performed using both single-energy and dual-energy scan modes. The specimen was stained with Oil Red O to evaluate lipiodol accumulation; this was considered the reference standard. Mutual information (MI) was used to evaluate the significance of radiological-pathological correlation. Estimated iodine content values on iodine material density images were compared with actual values obtained using mass spectroscopy. Results: Mean MI values were 0.69, 0.32, 0.83, 0.72, 0.65, and 0.58 for single-energy scan; iodine density images; and virtual monoenergetic images for energy levels of 40, 60, 80, and 100 keV, respectively. The MI value of the monochromatic image (40 keV) was the highest among all sequences. However, this was not significant compared with the single-energy scan (p = 0.81). A significant correlation was observed between the estimated and actual values of iodine content (Pearson's product moment coefficient = 0.70, p = 0.023). Conclusion: More accurate and quantitative lipiodol evaluation in targeted tumors after TACE can be achieved by applying DECT rather than SECT. [ABSTRACT FROM AUTHOR]

Hepatocellular carcinoma (HCC) remains a leading cause of cancer-related deaths worldwide. Recent advances in immunotherapies, targeted therapies, and combination treatments have significantly improved outcomes for many patients with HCC. This review summarizes key findings from the 2024 ASCO Annual Meeting, focusing on emerging therapies, including immune checkpoint inhibitors (ICIs), CAR-T cell therapies, oncolytic viruses, and locoregional treatments like transarterial chemoembolization (TACE) and hepatic arterial infusion chemotherapy (HAIC). ICIs, particularly when combined with other agents, have shown promising efficacy, though challenges such as immune-related adverse events and resistance mechanisms remain. CAR-T cell therapies and oncolytic viruses offer novel therapeutic avenues for advanced HCC, but their long-term efficacy in solid tumors is still under investigation. Locoregional therapies, especially in combination with systemic treatments, continue to play a critical role in managing unresectable HCC and improving conversion rates to surgical resection. Additionally, the potential of biomarkers, such as hypoxia scores and CTNNB1 mutations, is being explored to better personalize treatment and predict patient responses. These biomarkers could pave the way for more targeted and effective therapeutic strategies. Overall, the recent studies presented at the ASCO meeting highlight progress in HCC treatment, underscoring the importance of continued innovation. Future research should focus on overcoming resistance mechanisms, optimizing combination therapies, and integrating biomarker-driven approaches to improve patient outcomes and enhance personalized treatment strategies.

Objectives: The purpose of this study was to compare the safety and efficacy of drug-eluting bead (DEB) transarterial chemoembolization combined with lenvatinib and camrelizumab (DEB-TACE-Len-C) and DEB-TACE-Len for the treatment of unresectable hepatocellular carcinoma (uHCC). Methods: This retrospective study consecutively included uHCC patients who underwent DEB-TACE-Len-C or DEB-TACE-Len treatment at our hospital and Qujing Second People's Hospital from April 2020 to April 2022. In total, 85 patients were enrolled. There were 42 patients in the DEB-TACE-Len-C group and 43 patients in the DEB-TACE-Len group. The disease control rate (DCR), objective response rate (ORR), overall survival (OS), progression-free survival (PFS), and adverse events (AEs) were compared between the two groups, and the factors influencing OS and PFS were analysed. Results: The ORR, DCR, PFS and OS were significantly greater in the DEB-TACE-Len-C group than in the DEB-TACE-Len group (ORR: 76.2% vs. 46.5%, P = 0.005; DCR: 88.1% vs. 67.8%, P = 0.039; PFS: 10 months vs. 6 months, P < 0.0001; OS: 24 months vs. 16 months, P = 0.0038). Multivariate Cox proportional hazard regression analysis revealed that portal tumour thrombus (PVTT) and therapeutic approach were independent factors affecting PFS and OS. There were no statistically significant differences in the incidence of AEs between the two groups (P > 0.05). Conclusion: Compared with DEB-TACE-Len, DEB-TACE-Len-C is an effective treatment option that can improve the tumour therapeutic response and prolong the OS and PFS in uHCC patients.

Background: Transarterial chemoembolization (TACE) is recommended as a palliative treatment for patients of the B stage of the Barcelona Clinic Liver Cancer (BCLC) classification. Aims: To identify clinical, biological, and radiological predictors of survival in patients undergoing TACE and develop a pre-therapeutic prognostic score. Methods: 191 adult cirrhotic patients treated for HCC with TACE at the University Hospital (UH) of Clermont-Ferrand (France) from 2007–2017 were retrospectively included. We investigated the impact of baseline liver function, patient characteristics, and tumor burden on overall survival and developed a prognostic score. Results: Patients had a median age of 66 years and 126 patients were Child A. The AFP-DIAM score distinguishes two groups with a significant difference in survival time (median OS 28.3 months in patients with a score = 0 versus 17.7 months in patients with a score > 0). AFP-DIAM was validated on an external cohort, is well calibrated, and has the best discrimination capacity (C-index) as compared to NIACE, HAP, STATE, and SIX TO TWELVE. AFP-DIAM and SIX TO TWELVE are the more easy-to-use scores. When AFP-DIAM and the SIX TO TWELVE scores were tested in the same statistical model, results confirmed a better AFP-DIAM performance. Conclusions: The AFP-DIAM is an easy-to-use score which allows to distinguish two groups with different prognosis before the first TACE session. Its use could provide further support to BCLC system to guide the therapeutic strategy of patients with HCC. An easy-to-use score allows to distinguish two groups with a different median survival. Patient with a high score could receive immunotherapy as first-line treatment. [ABSTRACT FROM AUTHOR]

This study was to develop and validate a model for predicting who can benefit from multiple transcatheter arterial chemoembolization (TACE) in hepatocellular carcinoma (HCC) patients. 228 and 98 patients were included in the development and validation sets, respectively. The primary clinical endpoint was benefiting from consecutive multiple TACE treatments. Logistic regression analysis was used to screen the independent risk factors for the clinical endpoint. The independent risk factors were then used to construct the predictive model. The area under receiver operating characteristic (ROC) curves, calibration curves, and clinical decision curves were used to evaluate the predictive ability of the model. Multivariate Logistic regression analysis showed that complete envelope, hepatic lopes, tumor number, and alpha-fetoprotein (AFP) were independent risk factors for benefiting from multiple TACE in HCC patients. The area under the curve (AUC) of the model constructed by using independent risk factors in the development and validation sets was 0.843 (95% confidence interval [CI]: 0.784–0.902) and 0.828 (95%CI: 0.739–0.916), respectively. The calibration curves and clinical decision curves showed that the model had good predictive ability. The model established in this study has a good predictive effect on HCC patients who can benefit from multiple TACE. [ABSTRACT FROM AUTHOR]

Objective: Transcatheter Arterial Chemoembolization (TACE) is the first choice for the treatment of advanced-stage hepatocellular carcinoma (HCC). However, TACE suffers from a lack of specificity and rapid drug release. Herein, a targeted redox-responsive peptide (TRRP) was synthesized and used as a carrier of doxorubicin (DOX) to enhance the efficacy of TACE through tumor cells targeting and controlled drug release. Methods: TRRP has a high loading capacity of DOX and a sensitive drug release behavior at high glutathione (GSH) concentration. Moreover, TRRP could bind to the transferrin receptor on the surface of tumor cells, which enhanced the efficacy of TACE and reduced side effects of TACE. TACE with TRRP@DOX dispersed in lipiodol shows an enhanced therapeutic outcome compared to the treatment with DOX + lipiodol emulsion in orthotopic rat HCC models. Results: TRRP has a high loading capacity of DOX and a sensitive drug release behavior at GSH concentration. Moreover, TRRP could bind to the transferrin receptor on the surface of tumor cells, which enhanced the efficacy of TACE and reduced side effects of TACE. TACE with TRRP@DOX dispersed in lipiodol shows an enhanced therapeutic outcome compared to the treatment with DOX + lipiodol emulsion in orthotopic rat HCC models. Conclusions: This study demonstrated that TRRP was a promising therapeutic agent for enhancing TACE therapy for HCC treatment. [ABSTRACT FROM AUTHOR]

Purpose: To provide detailed reports on radiation doses during transarterial chemoembolization (TACE) in the cone-beam computed tomography (CBCT) era and to identify the associated factors. Methods: This retrospective study included 385 consecutive patients who underwent initial conventional TACE for hepatocellular carcinoma (HCC) between January 2016 and December 2017. In most cases, CBCT was performed at the common hepatic artery or celiac axis to confirm the location of the tumor and the three-dimensional hepatic artery anatomy. Superselective TACE was performed for all technically feasible cases. Information on total dose area product (DAP), total cumulative air kerma (CAK), fluoroscopy time, and DAP and CAK of each digital subtraction angiography (DSA) and CBCT scan was recorded. Multiple linear regression analysis was performed to identify the factors associated with increased DAP during TACE. Results: The mean values of total DAP and CAK were 165.2 ± 81.2 (Gy·cm²) and 837.1 ± 571.0 (mGy), respectively. The mean fluoroscopy time was 19.1 ± 10.3 min. The mean DAP caused by fluoroscopy, DSA, and CBCT was 51.8 ± 43.9, 28.0 ± 24.1, and 83.9 ± 42.1 Gy·cm², respectively. Male sex, a high body mass index, largest tumor size > 3 cm, presence of aberrant right and left hepatic arteries, and superselective TACE were identified as independent predictors of increased total DAP during TACE. Conclusion: We were able to provide detailed reports on radiation doses during TACE and associated factors. [ABSTRACT FROM AUTHOR]

Purpose: To create and evaluate prediction models of local tumor recurrence after successful conventional transcatheter arterial chemoembolization (c-TACE) via radiomics analysis of lipiodol deposition using cone-beam computed tomography (CBCT) images obtained at the completion of TACE. Materials and Methods: A total of 103 hepatocellular carcinoma nodules in 71 patients, who achieved a complete response (CR) based on the modified Response Evaluation Criteria in Solid Tumors 1 month after TACE, were categorized into two groups: prolonged CR and recurrence groups. Three types of areas were segmented on CBCT: whole segment (WS), tumor segment (TS), and peritumor segment (PS). From each segment, 105 radiomic features were extracted. The nodules were randomly divided into training and test datasets at a ratio of 7:3. Following feature reduction for each segment, three models (clinical, radiomics, and clinical–radiomics models) were developed to predict recurrence based on logistic regression. Results: The clinical–radiomics model of WS showed the best performance, with the area under the curve values of 0.853 (95% confidence interval: 0.765–0.941) in training and 0.752 (0.580–0.924) in test dataset. In the analysis of radiomic feature importance of all models, among all radiomic features, glcm_MaximumProbability, shape_MeshVolume and shape_MajorAxisLength had negative coefficients. In contrast, shape_SurfaceVolumeRatio, shape_Elongation, glszm_SizeZoneNonUniformityNormalized, and gldm_GrayLevelNonUniformity had positive coefficients. Conclusion: In this study, a machine-learning model based on cone-beam CT images obtained at the completion of c-TACE was able to predict local tumor recurrence after successful c-TACE. Nonuniform lipiodol deposition and irregular shapes may increase the likelihood of recurrence. [ABSTRACT FROM AUTHOR]

Introduction and Objectives: Although unlimited sessions of conventional transarterial chemoembolization (cTACE) may be performed for liver metastases, there is no data indicating when treatment becomes ineffective. This study aimed to determine the optimal number of repeat cTACE sessions for nonresponding patients before abandoning cTACE in patients with liver metastases. Materials and Methods: In this retrospective, single-institutional analysis, patients with liver metastases from neuroendocrine tumors (NET), colorectal carcinoma (CRC), and lung cancer who underwent consecutive cTACE sessions from 2001 to 2015 were studied. Quantitative European Association for Study of the Liver (qEASL) criteria were utilized for response assessment. The association between the number of cTACE and 2-year, 5-year, and overall survival was evaluated to estimate the optimal number of cTACE for each survival outcome. Results: Eighty-five patients underwent a total of 186 cTACE sessions for 117 liver metastases, of which 30.7 % responded to the first cTACE. For the target lesions that did not respond to the first, second, and third cTACE sessions, response rates after the second, third, and fourth cTACE sessions were 33.3 %, 23 %, and 25 %, respectively. ThefourthcTACEsessionwastheoptimalnumberfor2-yearsurvival (HR0.40;95 %CI:0.16-0.97; p=0.04),5-year survival(HR0.31;95%CI:0.11-0.87;p=0.02), and overall survival (HR0.35;95%CI:0.13-0.89;p=0.02). Conclusions: Repeat cTACE in the management of liver metastases from NET, CRC, and lung cancer was associated with improved patient survival. We recommend at least four cTACE sessions before switching to another treatment for nonresponding metastatic liver lesions. [ABSTRACT FROM AUTHOR]

Introduction and Objectives: Autoimmune liver diseases (AILD) are rare causes hepatocellular carcinoma (HCC), and data on the efficacy and tolerability of anti-tumor therapies are scarce. This pan-European study aimed to assess outcomes in AILD-HCC patients treated with tyrosine kinase inhibitors (TKIs) or transarterial chemoembolization (TACE) compared with patients with more common HCC etiologies, including viral, alcoholic or non-alcoholic fatty liver disease. Materials and Methods: 107 patients with HCC-AILD (AIH:55; PBC:52) treated at 13 European centres between 1996 and 2020 were included. 65 received TACE and 28 received TKI therapy. 43 (66 %) were female (median age 73 years) with HCC tumor stage BCLC A (34 %), B (46 %), C (9 %) or D (11 %). For each treatment type, propensity score matching was used to match AILD to non-AILD-HCC on a 1:1 basis, yielding in a final cohort of 130 TACE and 56 TKI patients for comparative analyses of median overall survival (mOS) and treatment tolerability. Results: HCC-AILD patients showed comparable mOS to controls for both TACE (19.5 vs. 22.1 months, p = 0.9) and TKI (15.4 vs. 15.1 months, p = 0.5). Adverse events were less frequent in AILD-HCC patients than controls (33 % % vs. 62 %, p = 0.003). For TKIs, there were no significant differences in adverse events (73% vs. 86%, p = 0.2) or interruption rates (44% vs. 36 %, p = 0.7). Conclusions: In summary, this study demonstrates comparable mOS for AILD-HCC patients undergoing local and systemic treatments, with better tolerability than HCC of other causes. TKIs remain important therapeutic options for AILD-HCC patients, particularly given their exclusion from recent immunotherapy trials. [ABSTRACT FROM AUTHOR]

Background: Hepatocellular carcinoma (HCC) is highly aggressive, with delayed diagnosis, poor prognosis, and a lack of comprehensive and accurate prognostic models to assist clinicians. This study aimed to construct an HCC prognosisrelated gene signature (HPRGS) and explore its clinical application value. Methods: TCGA-LIHC cohort was used for training, and the LIRI-JP cohort and HCC cDNA microarray were used for validation. Machine learning algorithms constructed a prognostic gene label for HCC. Kaplan-Meier (K-M), ROC curve, multiple analyses, algorithms, and online databases were used to analyze differences between high- and low-risk populations. A nomogram was constructed to facilitate clinical application. Results: We identified 119 differential genes based on transcriptome sequencing data from five independent HCC cohorts, and 53 of these genes were associated with overall survival (OS). Using 101 machine learning algorithms, the 10 most prognostic genes were selected. We constructed an HCC HPRGS with four genes (SOCS2, LCAT, ECT2, and TMEM106C). Good predictive performance of the HPRGS was confirmed by ROC, C-index, and K-M curves. Mutation analysis showed significant differences between the low- and high-risk patients. The low-risk group had a higher response to transcatheter arterial chemoembolization (TACE) and immunotherapy. Treatment response of highand low-risk groups to small-molecule drugs was predicted. Linifanib was a potential drug for high-risk populations. Multivariate analysis confirmed that HPRGS were independent prognostic factors in TCGA-LIHC. A nomogram provided a clinical practice reference. Conclusion: We constructed an HPRGS for HCC, which can accurately predict OS and guide the treatment decisions for patients with HCC.

Objective: Comparing the efficacy of transarterial chemoembolization (TACE) combined with lenvatinib plus tislelizumab (TLT) with TACE combined with lenvatinib (TL) for unresectable hepatocellular carcinoma, particularly in determining which patients can benefit more from the TLT treatment. Methods: From March 2021 to September 2023, a total of 169 patients from three centers were included in this study, with 103 patients receiving TLT and 66 patients receiving TL. The Kaplan-Meier method was utilized to evaluate the cumulative overall survival (OS) and progression-free survival (PFS) between the two groups and were assessed using the log-rank test. Subgroup analysis on tumor number, maximum tumor diameter, presence of portal vein thrombosis, AFP level, and Child-Pugh class were conducted. Results: The median OS was 26 months in the TLT group, and 20 months in the TL group. The median PFS was 14 months in the TLT group and 9 months in the TL group. The Kaplan-Meier curve demonstrated a significantly superior OS and PFS in the TLT group compared to the TL group. Subgroup analysis showed that for patients with a maximum tumor diameter greater than 7 cm, AFP > 400 ng/ml and accompanied by portal vein tumor thrombus, and Child-Pugh class A, there was a statistically significant difference in OS between TLT and TL groups. Conclusions: OS and PFS were significantly improved in patients who received TLT compared to those who received TL, patients with a largest tumor diameter greater than 7 cm, AFP > 400 ng/ml, Child-Pugh class A and PVTT appeared to derive more benefit.

Background: Recent studies have highlighted that TACE in conjunction with Lenvatinib (TACE-L) offers a promising adjunct therapy for advanced HCC patients, outperforming TACE plus Sorafenib (TACE-S). However, there has been a lack of research comparing these two regimens for intermediate HCC. Aims: This study aims to address the research gap by evaluating the efficacy of TACE-L versus TACE-S in intermediate HCC patients. Methods: A retrospective analysis was conducted on a cohort of consecutive intermediate HCC patients who received either TACE-L or TACE-S from November 2018 to December 2022. Portal vein width was assessed using abdominal NMRI or Doppler ultrasonography, and inflammatory markers were derived from routine blood counts. The primary outcomes of interest were overall survival (OS), progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), and adverse drug reactions (ADRs). Results: The study included 117 patients, with 56 in the TACE-S group and 61 in the TACE-L group. The TACE-S group demonstrated superior OS (HR = 1.704, 95% CI: 1.012–2.870, p = 0.045) compared to the TACE-L group. No significant difference was observed in PFS (HR:1.512, 95% CI: 0.988–2.313, p = 0.057) between the two groups. Subgroup analyses revealed that male patients, those with cirrhosis, and those with more than four tumors had better OS and PFS in the TACE-S group than in the TACE-L group. Inflammatory markers were comparable between the groups. The TACE-S group experienced a higher incidence of palmar-plantar erythrodysesthesia syndrome (PPE) (14/56 [25%] vs. 5/61 [8.1%], p = 0.014) but a lower incidence of hypertension (3/56 [5.3%] vs. 11/61 [18%], p = 0.035) compared to the TACE-L group. Conclusions: In patients with intermediate HCC, TACE-S was found to be more effective in terms of OS than TACE-L. No significant disparity was noted in PFS between the two treatment groups.

Introduction Methods Results Conclusion We investigated the clinical outcomes of stereotactic body radiation therapy (SBRT) alone versus SBRT after incomplete transarterial chemoembolization (TACE) for a single recurrent hepatocellular carcinoma (HCC) smaller than 5 cm.We retrospectively reviewed the medical records of patients who underwent SBRT for a single recurrent HCC ≤5 cm, without vascular invasion or extrahepatic metastasis. Patients were divided into the SBRT‐alone group and the TACE‐SBRT group. The primary outcome was the local control (LC) rate, and secondary outcomes were survivals and treatment‐related toxicities. We additionally conducted a propensity score matching (PSM) analysis.A total of 477 patients were available for analysis. Among them, 54 patients received SBRT without prior treatment to the target lesion (SBRT‐alone group), whereas 423 patients received SBRT for viable HCC after TACE (TACE‐SBRT group). The 3‐year LC rates did not differ between the two groups (SBRT‐alone group, 88.6% vs. TACE‐SBRT group, 89.6%, P = 0.918). The 3‐year rates of overall survival, out‐of‐field intrahepatic recurrence‐free survival and recurrence‐free survival were also not significantly different (P = 0.479, 0.290 and 0.273, respectively). Even after PSM, LC and survival rates at 3 years were not significantly different.SBRT alone demonstrated comparable local control and survival outcomes to SBRT following incomplete TACE. SBRT alone may be considered an alternative treatment option for a single recurrent HCC smaller than 5 cm when curative treatments or TACE are not feasible. [ABSTRACT FROM AUTHOR]

Background: Solid pseudopapillary neoplasm of the pancreas (SPN) is a rare and low-grade malignant tumor. It mainly occurs in women of reproductive age, accounting for approximately 1-3% of all pancreatic tumors. SPN has a low incidence rate and is difficult to diagnose before surgery. Some cases may show local infiltration, but distant metastasis rarely occurs. Currently, there is no standardized treatment protocol for SPN. Patient and methods: We have collected clinical data from 5 patients with solid pseudopapillary neoplasm (SPN) of the pancreas who presented with distant metastasis at our hospital. This study retrospectively analyzes their clinical manifestations, imaging characteristics, pathological findings, and treatment outcomes. The aim is to summarize the clinical features of SPN with distant metastasis, thereby improving the diagnosis, treatment, and prognosis prediction of this disease. This study also reviews relevant literature. Results: The median age of the 5 patients was 32 years old, with a male-tofemale ratio of 1:4. All patients underwent enhanced CT scans and were diagnosed with SPN through biopsy or surgical pathology. All 5 patients had liver metastases, and one patient had clavicular lymph node metastasis. Another patient had both lung and clavicular lymph node metastases. Three patients underwent curative surgery, one patient received chemotherapy combined with targeted immunotherapy and subsequently underwent TACE(Transcatheter arterial chemoembolization) and HAIC (Hepatic artery infusion chemotherapy) treatments due to progression. One patient received internal radiation therapy but experienced multiple relapses and eventually died due to complications. The follow-up period ranged from 7 to 53 months, with 2 patients succumbing to the disease. Conclusion: As a low-grade tumor, SPN has a low rate of distant metastasis, typically occurring in only 5%-15% of cases. These metastases often lack characteristic clinical symptoms. Diagnosis can only be confirmed after exclusion of other lesions through imaging and pathological examination. The primary treatment for metastatic SPN is curative surgery, which can lead to a favorable prognosis. [ABSTRACT FROM AUTHOR]

Simple Summary: Therapeutic response and survival outcomes in hepatocellular carcinoma (HCC) patients remain unsatisfactory, with a 5-year survival rate of less than 25%. The lack of molecular analysis of HCC tissue hinders the identification of precise predictors of disease progression and treatment outcomes. Analyzing the hepatic neoangiogenic transcriptomic signature can predict the biological aggressiveness of HCC and its resistance to therapies, offering a valuable diagnostic and prognostic tool that can significantly enhance the management of HCC. Background/Objectives: We evaluated the relationship between the neoangiogenic transcriptomic signature (nTS) and clinical symptoms, treatment outcomes, and survival in hepatocellular carcinoma (HCC) patients. Methods: This study prospectively followed 328 patients in the derivation and 256 in the validation cohort (with a median follow-up of 31 and 22 months, respectively). The nTS was associated with disease presentation, treatments administered, and overall survival rates. Additionally, this study investigated how multiple treatments influenced changes in nTS status and alterations in microRNA expression. Results: The nTS was identified in 27.4% of patients, linked to aggressive features like multifocality and elevated alpha-fetoprotein (AFP), a pattern consistent with that of the validation cohort. Most patients in both cohorts received treatment for HCC. nTS+ patients had limited access to, and benefited less from, liver transplantation or radiofrequency ablation (RFA) compared to nTS− patients. By the end, 78.9% had died, with nTS− patients showing better median survival and response to treatments than their nTS+ counterparts, who had lower survival across all treatment types. Among those who received transarterial chemoembolization (TACE), 31.2% (21/80 patients after the initial treatment and another four following a second TACE) transitioned from an nTS− to an nTS+ status. This shift was associated with lower survival and alterations in microRNA expressions related to oncogenic pathways. Conclusions: The nTS markedly influences treatment eligibility and survival in patients with HCC. Notably, the nTS can develop after repeated TACE procedures, significantly impacting patient survival and altering oncogenic microRNA expression patterns. These findings highlight the critical role of the nTS in guiding treatment decisions and prognostication in HCC management. [ABSTRACT FROM AUTHOR]

Simple Summary: In patients with hepatocellular carcinoma (HCC), predicting survival after treatment is crucial for informed decision-making. This retrospective study investigated how muscle health (myosteatosis) and liver function (the albumin–bilirubin grade) influence survival outcomes in patients undergoing transarterial chemoembolization (TACE), resulting in the development of the Myo-ALBI prognostic score. The Myo-ALBI score was found to be a more accurate tool for predicting survival compared to existing methods. This study highlights the potential of the Myo-ALBI score to help clinicians personalize treatments and improve patient outcomes. Objective: This study aimed to investigate the prognostic value of preoperative myosteatosis and the albumin–bilirubin (ALBI) grade in patients with hepatocellular carcinoma (HCC) undergoing transarterial chemoembolization (TACE) and develop a robust prognostic score based on these factors. Methods: Patients with HCC who underwent TACE between January 2009 and December 2020 were included. Multivariate Cox regression analysis identified prognostic factors. CT-based body composition parameters were acquired from baseline abdominal CT images at the level of the third lumbar vertebra. A prognostic score (Myo-ALBI) was developed based on the presence of preoperative myosteatosis and the ALBI grade, and its prognostic value was evaluated. Results: Of 446 patients, 63% were male, and the mean age was 62.4 years. Preoperative myosteatosis was present in 41.5% of patients. The BCLC stages were mostly B (67.9%). Multivariate analysis shows that preoperative myosteatosis, ALBI grade 2, and ALBI grade 3 were independent prognostic factors. The Myo-ALBI grade was incorporated into a prognostic model, including alpha-fetoprotein and up-to-seven criteria, to generate a nomogram. The C-index of the nomogram based on the Myo-ALBI grade (0.743) was significantly higher than the non-Myo-ALBI nomogram (0.677), the up-to-seven criteria (0.653), the ALBI grade (0.616), and the Child–Pugh class (0.573) (all p < 0.05). The t-ROC curve for the nomogram was consistently superior to the other models throughout the observation period in all patients and the BCLC-B subgroup. Conclusions: The combination of preoperative CT-derived myosteatosis and ALBI grade enhances prognostication for patients with unresectable HCC undergoing TACE. The Myo-ALBI nomogram constructed in this study could support individualized prognosis prediction, assisting in treatment decision-making for HCC patients. [ABSTRACT FROM AUTHOR]

Introduction: The most frequently used first-line treatment in patients with advanced hepatocellular carcinoma (HCC) is atezolizumab plus bevacizumab. Upon progression after this treatment, the standard of care in many countries is sorafenib, due to the lack of reimbursement for other drugs. Several randomized trials are currently underway to clarify the best second-line therapy in patients with HCC. This real-world study aimed to compare outcomes reached by lenvatinib and sorafenib second-line therapy in this setting. Methods: The overall cohort included 891 patients with HCC from 5 countries treated with atezolizumab plus bevacizumab in first-line setting between October 2018 and April 2022. At the data cut-off (May 2022), 41.5% of patients were continuing a first-line treatment, 5.5% were lost at follow-up, and 53.0% of patients had progressive disease after first-line therapy. 51.5% of patients with progressive disease received a second-line treatment, while 48.5% did not receive any subsequent therapy. Between patients receiving second-line treatment, 11.1% of patients underwent transarterial chemoembolization, 21.0% received sorafenib, 35.4% underwent lenvatinib, and 32.5% were treated with other drugs. Results: Lenvatinib second-line subgroup achieved a median overall survival (mOS) of 18.9 months, significative longer (p = 0.01; hazard ratio [HR]: 2.24) compared to sorafenib subgroup that reached a mOS of 14.3 months. The multivariate analysis highlighted albumin-bilirubin 1 grade (p < 0.01; HR: 5.23) and lenvatinib second-line therapy (p = 0.01; HR: 2.18) as positive prognostic factors for OS. The forest plot highlighted a positive trend in terms of OS in favor of patients treated with lenvatinib second-line regardless of baseline characteristics before first-line therapy. Conclusion: These results suggest that, in patients with HCC progressed to first-line atezolizumab plus bevacizumab, lenvatinib second-line therapy is associated to an improved survival compared to sorafenib.

This study aimed to evaluate how the timing of transarterial chemoembolization (TACE) relative to systemic therapy (tyrosine-kinase inhibitors [TKIs] and immune checkpoint inhibitors [ICIs]) influences oncological outcomes in patients with hepatocellular carcinoma (HCC). A retrospective analysis was conducted on HCC patients treated with TACE plus TKIs and ICIs from January 2018 to February 2023. We compared objective response rate (ORR), disease control rate (DCR), overall survival (OS), and progression-free survival (PFS) between patients receiving TACE before versus after systemic therapies. Multivariate Cox regression analyses identified potential prognostic factors. Of the 194 patients enrolled, 111 received TACE before systemic therapies, and 83 after. The median age at diagnosis was 52.8 years. There were no significant differences in ORR (40.72% vs. 30.41%, p = 0.989) or DCR (48.45% vs. 35.57%, p = 0.770) between the groups. Likewise, OS (18.73 vs. 18.20 months, p = 0.091) and PFS (11.53 vs. 10.05 months, p = 0.336) were similar regardless of treatment sequence. In the result of Cox analysis, a 20% decrease in AFP from baseline at one month was associated with improved OS (HR = 0.35, 95% CI 0.17–0.70, p = 0.003) and PFS (HR = 0.69, 95% CI 0.49–0.96, p = 0.028). Large tumor size (≥ 10 cm) was a poor prognostic factor for OS (HR = 2.12, 95% CI 1.07–4.21, p = 0.032), and the presence of portal vein tumor thrombus adversely affected PFS (HR = 2.31, 95% CI 1.47–3.62, p < 0.001). The sequencing of TACE and systemic therapies does not significantly impact the prognosis of advanced HCC. A 20% reduction in AFP within one month of treatment commencement emerges as a protective prognostic factor for HCC. [ABSTRACT FROM AUTHOR]

Background & aims: The benefit of postoperative adjuvant transcatheter arterial chemoembolization (pTACE) for patients with hepatocellular carcinoma (HCC), especially those with Child-Pugh (CP) B, remains controversial. This study aimed to assess the survival benefit of pTACE for HCC patients with CP B. Methods: Data from 297 HCC patients with CP B7 or B8 were analyzed, dividing them into groups with and without pTACE (70, 23.6% vs. 227, 76.4%). Propensity score matching (PSM) was used to control for confounding bias, and competing-risk regression was applied to address bias from non-cancer-specific death (NCSD). Results: Preliminary findings suggest that pTACE did not increase the incidence of severe complications in HCC patients with CP B7 or B8. Survival analysis indicated that the group receiving pTACE had better overall survival and recurrence-free survival than the group without pTACE after PSM. Furthermore, competitive risk analysis revealed that pTACE was an independent prognostic factor associated with reduced cancer-specific death incidence (subdistribution hazard ratio [SHR] 0.644, 95%CI: 0.378–0.784, P = 0.011) and recurrence (SHR 0.635, 95% CI: 0.379–0.855, P = 0.001). Importantly, pTACE did not increase NCSD. Subgroup analysis corroborated these results. Conclusion: Adjuvant TACE demonstrates the potential to significantly enhance the long-term prognosis of HCC patients with CP B7 or B8 following hepatectomy, particularly those with multiple tumors, large tumor size, macrovascular or microvascular invasion, and narrow resection margin. Hence, pTACE should be considered for patients at high risk of recurrence following thorough evaluation. [ABSTRACT FROM AUTHOR]

Background: The aim of this study was to conduct a systematic review and meta-analysis to comprehensively evaluate the performance and methodological quality of artificial intelligence (AI) in predicting recurrence after single first-line treatment for liver cancer. Methods: A rigorous and systematic evaluation was conducted on the AI studies related to recurrence after single first-line treatment for liver cancer, retrieved from the PubMed, Embase, Web of Science, Cochrane Library, and CNKI databases. The area under the curve (AUC), sensitivity (SENC), and specificity (SPEC) of each study were extracted for meta-analysis. Results: Six percutaneous ablation (PA) studies, 16 surgical resection (SR) studies, and 5 transarterial chemoembolization (TACE) studies were included in the meta-analysis for predicting recurrence after hepatocellular carcinoma (HCC) treatment, respectively. Four SR studies and 2 PA studies were included in the meta-analysis for recurrence after intrahepatic cholangiocarcinoma (ICC) and colorectal cancer liver metastasis (CRLM) treatment. The pooled SENC, SEPC, and AUC of AI in predicting recurrence after primary HCC treatment via PA, SR, and TACE were 0.78, 0.90, and 0.92; 0.81, 0.77, and 0.86; and 0.73, 0.79, and 0.79, respectively. The values for ICC treated with SR and CRLM treated with PA were 0.85, 0.71, 0.86 and 0.69, 0.63,0.74, respectively. Conclusion: This systematic review and meta-analysis demonstrates the comprehensive application value of AI in predicting recurrence after a single first-line treatment of liver cancer, with satisfactory results, indicating the clinical translation potential of AI in predicting recurrence after liver cancer treatment.

Purpose: The prognosis of patients with hepatocellular carcinoma (HCC) and portal vein tumor thrombus (PVTT) is extremely poor, and systemic therapy is currently the mainstream treatment. This study aimed to assess the efficacy and safety of lenvatinib combined with anti–programmed cell death-1 antibodies and transcatheter arterial chemoembolization (triple therapy) in patients with HCC and PVTT. Materials and Methods: This retrospective multicenter study included patients with HCC and PVTT who received triple therapy, were aged between 18 and 75 years, classified as Child-Pugh class A or B, and had at least one measurable lesion. The overall survival (OS), progression-free survival (PFS), objective response rates, and disease control rates were analyzed to assess efficacy. Treatment-related adverse events were analyzed to assess safety profiles. Results: During a median follow-up of 11.23 months (range, 3.07 to 34.37 months), the median OS was greater than 24 months, and median PFS was 12.53 months. The 2-year OS rate was 54.9%. The objective response rate and disease control rate were 69.8% (74/106) and 84.0% (89/106), respectively; 20.8% (22/106) of the patients experienced grade 3/4 treatment-related adverse events and no treatment-related deaths occurred. The conversion rate to liver resection was 31.1% (33/106), with manageable postoperative complications. The median OS was not reached in the surgery group, but was 19.08 months in the non-surgery group. The median PFS in the surgery and non-surgery groups were 20.50 and 9.00 months, respectively. Conclusion: Triple therapy showed promising survival benefits and high response rates in patients with HCC and PVTT, with manageable adverse effects. [ABSTRACT FROM AUTHOR]

Sorafenib is a recommended first-line therapy for advanced hepatocellular carcinoma (HCC). However, when used as monotherapy in patients in advanced stages, the prognosis remains suboptimal. This study aimed to evaluate the impact of transcatheter arterial chemoembolization (TACE) on survival outcomes in patients with advanced HCC treated with sorafenib, as well as to identify which subgroups may benefit most from the addition of TACE. This single-institution retrospective study included 92 patients diagnosed with Barcelona Clinic liver cancer (BCLC) stage C HCC who received sorafenib between August 2011 and December 2016. We assessed the influence of different treatment modalities on prognosis using multivariable regression analysis. Patients were categorized into three subgroups: those with vascular invasion, those with distant metastasis, and those with both risk factors. Baseline comparisons indicated no significant differences in clinical characteristics among the three groups. Survival analysis showed no statistically significant difference in overall survival (OS) between the subgroups. However, in the overall cohort of patients with BCLC stage C, multifactorial Cox regression analysis identified pre-treatment alpha-fetoprotein (AFP) levels (p = 0.020), alkaline phosphatase (ALP) levels (p = 0.034), and the absence of combination TACE therapy (p = 0.008) as independent risk factors affecting OS. Further subgroup Cox analyses revealed that the lack of combination TACE therapy was an independent risk factor for OS in both the vascular invasion group and the group with both risk factors. In conclusion, for patients with advanced HCC receiving sorafenib, the addition of TACE may enhance long-term survival, particularly in those with vascular invasion. [ABSTRACT FROM AUTHOR]

Hepatocellular carcinoma (HCC), the most prevalent form of liver cancer globally, poses a substantial health burden. Influenced by risk factors such as hepatitis B or C virus infections, chronic consumption of alcohol, and metabolic dysfunction, its exact etiology likely involves a complex interplay between viral infection, hepatocyte mutations, and chronic liver diseases like cirrhosis and metabolic dysfunction-associated steatohepatitis, and demographic variables like sex, race, and age. Disease stage significantly impacts the prognosis of HCC. There is significant potential for life-saving and socioeconomic benefits through the implementation of surveillance programs and the introduction of low-cost screening measures for high-risk groups; these screening measures include ultrasound imaging and blood tests. Treatment options for HCC encompass liver resection, transplantation, transarterial chemoembolization, radiation therapy, chemotherapy, targeted therapy, and immunotherapy. Despite therapeutic advances, treating advanced HCC remains challenging, emphasizing the need for continued efforts in prevention, early detection, and development of treatments to improve prognosis and long-term survival.

Introduction: Patients with hepatocellular carcinoma (HCC) and inferior vena cava tumor thrombus (IVCTT) have poor prognosis. Combination therapy involving the blockade of programmed cell death protein 1 (PD-1) and tyrosine kinase inhibitors is an efficient treatment strategy for advanced HCC. However, surgical treatment after a combination of systemic therapy and transarterial chemoembolization (TACE) for HCC with IVCTT has not been widely reported, and the efficacy and safety of this treatment have not been studied. Methods: In the 21 cases reported herein, the patients were treated with TACE, lenvatinib, and PD-1 blockade. The treatment responses, progression-free survival (PFS), overall survival (OS), disease control rate, and toxicities were evaluated, and the related literature was reviewed. Results: The overall response and disease control rates were 66.7% and 85.7%, respectively. The median PFS time was 16.0 months, with a 1-year PFS rate of 55.60%. The median OS was not reached, with a 1-year OS rate of 66.70%. Four patients underwent hepatectomy without serious complications and survived for 29.1, 24.7, 14.2, and 13.8 months. Three patients survived tumor-free, and 1 patient experienced intrahepatic recurrence. Pathological complete response and major pathological responses were observed in 1 and 3 patients, respectively. Treatment-related adverse events of any grade occurred in 8/9 patients (88.9%), and grade 3 treatment-related adverse events occurred in 1 patient. Conclusion: The combination of TACE, lenvatinib, and PD-1 is effective for HCC with IVCTT and has acceptable adverse effects. [ABSTRACT FROM AUTHOR]

Aim: To investigate the characteristics and prognosis of patients with advanced hepatocellular carcinoma (HCC) treated with atezolizumab and bevacizumab (Atz/Bev) who achieved a complete response (CR) according to the modified Response Evaluation Criteria in Solid Tumors (mRECIST). Methods: A total of 120 patients with Eastern Cooperative Oncology Group performance status (PS) 0 or 1 and Child–Pugh A at the start of Atz/Bev treatment were included. Barcelona Clinic Liver Cancer stage C was recorded in 59 patients. Results: The CR rate with Atz/Bev alone was 15.0%. The median time to CR was 3.4 months, and the median duration of CR was 15.6 months. A significant factor associated with achieving CR with Atz/Bev alone was an AFP ratio of 0.34 or less at 3 weeks. Adding transarterial chemoembolization (TACE) in the six patients who achieved a partial response increased the overall CR rate to 20%. Among the 24 patients who achieved CR, the median progression-free survival was 19.3 months, the median overall survival was not reached, and 14 patients (58.3%) were able to discontinue Atz/Bev and achieve a drug-free status. Twelve of these patients developed progressive disease (PD), but eleven successfully received post-PD treatments and responded well. Conclusions: Achieving CR by mRECIST using Atz/Bev alone or with additional TACE can be expected to offer an extremely favorable prognosis. [ABSTRACT FROM AUTHOR]

This retrospective study aimed to evaluate the impact of atezolizumab plus bevacizumab–transcatheter arterial chemoembolization (TACE) sequential therapy in unresectable hepatocellular carcinoma (HCC), especially in patients with intermediate-stage HCC. A total of 212 patients were enrolled and categorized into the Atez/Bev-TACE sequential therapy (n = 23) or Atez/Bev monotherapy group (n = 189) between 2020 and 2024. Of these, patients with intermediate-stage HCC were categorized into the Atez/Bev-TACE sequential (n = 18) or Atez/Bev monotherapy group (n = 91). The best objective response rate, disease control rate, and median progression-free survival (PFS) after TACE were 73.9%, 82.6%, and 6.1 months, respectively. The PFS after TACE was significantly higher in the Atez/Bev sequential therapy group than in the no-Atez/Bev-administration group after TACE (6.9 months vs. 5.0 months, p = 0.025). The median overall survival (OS) was significantly higher in the Atez/Bev-TACE sequential therapy group than in the Atez/Bev monotherapy group for intermediate-stage HCC (34.9 months vs. 17.8 months; p = 0.016). Independent factors associated with OS were low alpha-fetoprotein levels, modified albumin–bilirubin 1 or 2a levels, and Atez/Bev-TACE sequential therapy. Atez/Bev-TACE sequential therapy improved prognosis compared with Atez/Bev monotherapy in patients with intermediate-stage HCC. Moreover, Atez/Bev should be readministered after TACE.

Introduction: The effectiveness of transarterial chemoembolization (TACE) in treating hepatocellular carcinoma (HCC) has been well established. The differential impacts of drug-eluting bead TACE (DEB-TACE) as opposed to conventional TACE (cTACE) on vascular changes, such as arterial-portal venous shunts (APSs), have been recognized. However, their subsequent effects on treatment outcomes have not been fully explored. This study aims to identify risk factors associated with the occurrence of APS in HCC patients treated with DEB-TACE and to evaluate its impact on patient survival. Methods: A retrospective analysis was conducted from January 2012 to December 2018 including 74 HCC patients receiving DEB-TACE as initial treatment and a 1:1 cTACE. Kaplan-Meier analysis estimated overall survival (OS) and progression-free survival (PFS). Logistic regression identified significant risk factors for APS occurrence after DEB-TACE. Results: APS incidence was significantly higher after DEB-TACE than cTACE (46.0% vs. 16.2%, p < 0.001). There was no significant difference in median OS between APS and non-APS groups after DEB-TACE: 50 months (24.6–75.4) versus 26.9 months (19.5–43.2), p = 0.111; median PFS was 15.6 months (4.1–27.1) and 9.5 months (6.8–12.1) for the two groups, respectively, p = 0.065. Risk factors for APS occurrence after DEB-TACE were more than two feeding arteries (OR: 7.25, 95% CI: 1.82–28.95, p = 0.005) and non-selective embolization (OR: 8.02, 95% CI: 2.30–27.95, p = 0.001). Conclusion: APS occurrence was higher in DEB-TACE-treated HCC patients, but it did not significantly affect OS and PFS. More than two feeding arteries and non-selective embolization were significant risk factors for APS occurrence after DEB-TACE. [ABSTRACT FROM AUTHOR]

Background: The objectives were to assess the safety and efficacy of drug-eluting bead transarterial chemoembolization (DEB-TACE) as locoregional therapy (LRT) in hepatocellular carcinoma (HCC) before liver transplantation (LT) beyond Hangzhou criteria (HC) and to analyze the prognostic factors. Methods: Forty patients with HCC beyond HC who received DEB-TACE only before LT were retrospectively analyzed between January 2017 and December 2022. Data on patient demographics, disease characteristics, treatment response, and adverse events (AE) were collected. Overall survival (OS) and recurrence-free survival (RFS) were evaluated with Kaplan-Meier curves. Univariate and multivariate Cox regression analyses were performed to identify factors independently associated with RFS and OS. Results: All patients successfully underwent LT following DEB-TACE with a mean interval of 2.3 months. The objective response rates (ORRs) for these patients following DEB-TACE was 82.5%. The primary AE was post-embolization syndrome (PES), with affected patients experiencing grades I and II. The median RFS and OS were 12.0 months (95%CI: 0.0-30.1) and 52.0 months (95%CI: 11.8–92.2) over the follow-up period until December 2022. The 2-year RFS and OS rates were 42.5%, and 67.5%. Multivariate analyses revealed Child-Pugh classification (HR = 6.24; 95%CI,1.83–21.24; P = 0.01) and macrovascular invasion (MAV) (HR = 3.89; 95%CI,1.07–14.15; P = 0.04) were both significant independent predictors of OS. Conclusions: DEB-TACE can serve as a safe and effective LRT in HCC patients beyond HC before LT, and can improve the prognosis of patients, especially without MAV. The higher Child–Pugh classification and MAV are independent prognostic factors after LT. [ABSTRACT FROM AUTHOR]

Background: This study aimed to compare the survival outcomes of transarterial chemoembolization (TACE) between patients with early recurrent hepatocellular carcinoma (rHCC) after hepatic resection, stratified by cytokeratin (CK) 19 expression. Methods: A retrospective analysis was conducted on 63 patients with early rHCC after hepatic resection who underwent TACE between January 2017 and December 2021. Patients were divided into two groups based on CK19 expression: CK19-negative (n=31) and CK19-positive (n=32). Overall survival (OS) and progression-free survival (PFS) were compared between the two groups using the Kaplan-Meier method and log-rank test. Cox regression analysis was performed to identify independent risk factors for OS and PFS. Results: The CK19-negative group demonstrated a significantly longer median OS compared to the CK19-positive group (635 days vs. 432 days, p=0.013). Similarly, the CK19-negative group had a longer median PFS than the CK19-positive group (291 days vs. 117 days, p=0.014). Multivariate Cox analysis identified Child-Pugh A grade, CK19-negative expression, and increased TACE sessions as protective factors for OS. No severe TACE-related adverse events were observed. Conclusion: In patients with early rHCC after hepatic resection, those with CK19-positive expression had poorer survival outcomes following TACE compared to CK19-negative patients. These findings suggest the need for additional therapies to improve survival in CK19-positive individuals. [ABSTRACT FROM AUTHOR]

Objectives: This study aimed to compare the combination therapy of transarterial chemoembolization (TACE) and microwave ablation (MWA) with MWA alone in treating liver metastases from colorectal cancer (LMCRC). Materials and methods: In this retrospective study, a total of 251 patients with unresectable and not to chemotherapy responding LMCRC were included. Group A consisted of 184 patients (104 male and 80 females; mean age: 64 ± 11.4 years) with 442 metastases who received a combination of TACE and MWA. A total of 67 patients (49 male and 18 females; mean age: 63.2 ± 11.8 years) with 173 metastases patients were included in group B, who received only MWA. Parameters assessed were local tumor progression (LTP), hepatic distant tumor progression (hDTP), hepatic progression-free survival (hPFS), and overall survival (OS). Results: The rate of LTP was 4.9% in group A and 4.5% in group B (p-value: 0.062). The rate of hDTP was 71.7% and 83.6% for groups A and B (p-value: 0.81), respectively. The mean hPFS was 13.8 months (95% CI 10.9–16.8) for group A and 8.1 months (95% CI 6.1–10.1) for group B (p-value: 0.03). The median OS time for group A was 30 months (95% CI 26–34), with 1-, 2-, 3-, and 4-year OS rates of 84.2%, 61.1%, 40.8% and 31.3%, respectively. In group B however, the median OS time was 26 months (95% CI 18–34) with 1-, 2-, 3-, and 4-year OS rates of 82.3%, 53.2%, 34.6% and 28.2%, respectively (p-value: 0.67). Conclusion: The combination therapy of TACE and MWA is superior to the monotherapy of MWA for LMCRC, especially regarding hDTP, hPFS and OS. [ABSTRACT FROM AUTHOR]

Pancreatic ductal adenocarcinoma (PDAC) has a low survival rate and limited treatment options. Concurrent chemoradiotherapy is considered beneficial to improve tumor control, but the low drug bioavailability at tumor site and the low radiation tolerance of surrounding healthy organs greatly limits its effectiveness. Lipiodol, a natural drug carrier used in clinical transarterial chemoembolization, has shown potential as a radiosensitizer due to its high Z element iodine composition. Thus, this study aims to repurpose lipiodol as a sensitizer to simultaneously enhance chemo- and radiotherapy for PDAC. To this end, a stable lipiodol emulsion (IOE) loaded with gemcitabine is designed using clinically approved surfactants. At in vivo level, IOE demonstrates better radiotherapeutic effect than existing nanoradiosensitizers and enhanced drug bioavailability over free drug, leading to significant tumor inhibition and improved survival rates under concurrent chemo-radiotherapy. This may due to the sustained drug release, homogenous spatial distribution, and long-term retention ability of IOE in solid PDAC tumor. Furthermore, to better understand the functioning mechanism of drug-loaded IOE, in vitro study is conducted to reveal the ROS- and DNA damage-related therapeutic pathways. Lastly, a comprehensive toxicity assessment also proves the good biocompatibility and safety of as-prepared IOE. This study offers a clinically feasible sensitizer for simultaneous chemoradiotherapy and holds potential for other types of cancer treatment in clinics. [Display omitted] • Lipiodol emulsion (IOE) functions as a simultaneous radiochemosensitizer for PDAC. • IOE increases drug bioavailability, retentivity and diffusion in solid tumor. • Oxidative stress and DNA damage-based therapeutic mechanism is verified. • IOE possesses good biosafety.

Purpose: Non-invasive methods are urgently needed to assess the efficacy of transarterial chemoembolization (TACE) and to identify patients with hepatocellular carcinoma (HCC) who may benefit from this procedure. This study, therefore, aimed to investigate the predictive ability of tumor growth patterns and radiomics features from contrast-enhanced magnetic resonance imaging (CE-MRI) in predicting tumor response to TACE among patients with HCC. Patients and Methods: A retrospective study was conducted on 133 patients with HCC who underwent TACE at three centers between January 2015 and April 2023. Enrolled patients were divided into training, testing, and validation cohorts. Rim arterial phase hyperenhancement (Rim APHE), tumor growth patterns, nonperipheral washout, markedly low apparent diffusion coefficient (ADC) value, intratumoral arteries, and clinical baseline features were documented for all patients. Radiomics features were extracted from the intratumoral and peritumoral regions across the three phases of CE-MRI. Seven prediction models were developed, and their performances were evaluated using receiver operating characteristic (ROC) and decision curve analysis (DCA). Results: Tumor growth patterns and albumin-bilirubin (ALBI) score were significantly correlated with tumor response. Tumor growth patterns also showed a positive correlation with tumor burden (r = 0.634, P = 0.000). The Peritumor (AUC = 0.85, 0.71, and 0.77), Clinics_Peritumor (AUC = 0.86, 0.77, and 0.81), and Tumor_Peritumor (AUC = 0.87, 0.77, and 0.80) models significantly outperformed the Clinics and Tumor models (P < 0.05), while the Clinics_Tumor_Peritumor model (AUC = 0.88, 0.81, and 0.81) outperformed the Clinics (AUC = 0.67, 0.77, and 0.75), Tumor (AUC = 0.78, 0.72, and 0.68), and Clinics_Tumor (AUC = 0.82, 0.83, and 0.78) models (P < 0.05 or 0.053, respectively). The DCA curve demonstrated better predictive performance within a specific threshold probability range for Clinics_Tumor_Peritumor. Conclusion: Combining tumor growth patterns, intra- and peri-tumoral radiomics features, and ALBI score could be a robust tool for non-invasive and personalized prediction of treatment response to TACE in patients with HCC.

Purpose: There are insufficient data about the optimal treatment for older patients with recurring medium or large hepatocellular carcinoma (HCC). The study intended to assess the effect of transcatheter arterial chemoembolization combined with microwave ablation (TACE-MWA) in an elderly cohort through a retrospective analysis. Methods: From 2011 to 2018, a cohort of individuals (age ≥ 70 years) with recurrent HCC tumors ranging from 3.1 cm to 7 cm underwent either a combination treatment of TACE and MWA (n = 43) or surgical intervention (n = 33). Using the Inverse Probability of Treatment Weighting (IPTW) technique, factors of disease-free survival (DFS), overall survival (OS), and rates of major adverse events were analyzed, retrospectively. Results: The group that underwent surgery had a greater history of alcohol use before treatment (P= 0.001), as well as a higher Barcelona Clinic Liver Cancer (BCLC) stage for the primary tumor before treatment (P= 0.014) and a higher primary tumor location before treatment (P= 0.045). The TACE-MWA group had DFS rates of 86.2%, 68.8%, and 60.4% at 1, 3, and 5 years, while the surgery group had rates of 53.0%, 42.2%, and 25.8% at the same time points. In the TACE-MWA treatment group, survival rates at 1 year, 3 years, and 5 years post-treatment were recorded as 93.0%, 80.8%, and 65.7%, respectively, while in the surgery group, they were 62.7%, 46.9%, and 42.6%. In the univariate analysis using IPTW, the type of treatment was found to have a significant correlation with disease progression (hazard ratio [HR] 0.41, 95% CI 0.20– 0.86, P=0.017). IPTW multivariate analysis showed that treatment modality (HR, 0.35; 95% CI, 0.17 to 0.79; P= 0.011) was the only significant prognostic factor for OS. Conclusion: In elderly patients with recurrent 3.1 cm≤ HCC ≤ 7 cm, TACE-WMA was superior to surgery in the respects of DFS and OS. [ABSTRACT FROM AUTHOR]

To develop a model for predicting the overall survival (OS) of hepatocellular carcinoma (HCC) patients after transarterial chemoembolization (TACE) on the basis of multisequence MRI radiomic features and clinical variables. Methods: The DCE-MRI and clinical data of 116 HCC patients treated with TACE for the first time were retrospectively analyzed. The included patients were randomly divided into training and validation cohorts at a ratio of 7:3. Univariate and multivariate Cox proportional hazards regression models were used to identify independent risk factors that affect the OS of patients with HCC after TACE. Radiomic features were extracted from the sequences of FS-T2W images and arterial-phase (A) and portal venous-phase (P) axial DCE-MR images. The LASSO method was used to select the best radiomic features. Logistic regression was used to establish a radiomic model of each sequence, a joint model of MRI features (M model) combined the radiomic features of all the sequences, and a radiomic-clinical model (M-C model) that integrated the radiomic signatures and clinically independent predictors. The diagnostic performance of each model was evaluated as the area under the receiver operating characteristic (ROC) curve (AUC). Results: The Child–Turcotte–Pugh (CTP) score and neutrophil-to-lymphocyte ratio (NLR) –platelet–to–lymphocyte ratio (PLR) were found to be independent risk factors that affect the OS of patients with HCC treated with TACE. The AUCs of the FS-T2WI, A, P, M, and M-C models for predicting the OS of HCC patients after TACE treatment were 0.779, 0.803, 0.745, 0.858 and 0.893, respectively, in the training group and 0.635, 0.651, 0.644, 0.778 and 0.803, respectively, in the validation group. The M-C model had the best predictive performance. Conclusion: Multiparameter MRI-based radiomic features may be helpful for predicting OS after TACE treatment in HCC patients. The inclusion of clinical indicators such as inflammation scores can improve the predictive performance. [ABSTRACT FROM AUTHOR]

Objective response rate (ORR), overall survival (OS), and progression-free survival (PFS); and safety was assessed using the frequency of key adverse events (AEs). Results: Among the 76 patients included, the median maximum tumor diameter was 12.4 cm (range, 7.0– 23.4 cm). The overall ORRs based on mRECIST and RECIST 1.1 criteria were 94.1% and 51.5%, respectively. The median OS was 28.1 months (95% CI, 22.7– 33.4), and the median PFS was 11.7 months (95% CI, 7.7– 15.8). All patients experienced AEs, but only 18.4% experienced grade 3 or 4 AEs, there was no treatment-related mortality. Conclusion: In this single-center, retrospective study, our results suggested that FOLFOX-HAIC with sequential DEB-TACE demonstrated promising efficacy and safety for patients with unresectable HCC with a maximum tumor diameter of ≥ 7 cm.

Objective response rate (ORR), overall survival (OS), and progression-free survival (PFS) as outcomes. Predictors for OS and PFS were also analyzed. Treatment-related adverse events (TRAEs) were recorded and assessed. Results: Ninety-two patients were enrolled in this study, with a median follow-up duration of 14.1 months. The ORRs based on the modified Response Evaluation Criteria in Solid Tumors (RECIST) and RECIST 1.1 criteria were 54.3% and 41.3%, respectively. The median OS and PFS of the patients were 15.9 months [95% confidence interval (CI), 14.5– 17.2 months] and 9.1 months (95% CI, 7.4– 10.8 months), respectively. Multivariate analyses revealed that the Eastern Cooperative Oncology Group score and neutrophil‒lymphocyte ratio were independent risk factors for OS, whereas tumor size and extrahepatic metastasis were independent risk factors for PFS. Grade 3/4 TRAEs occurred in 16.3% (15/92) of the patients and were controlled conservatively. Conclusion: The combination of Atezo/Bev with TACE demonstrated acceptable synergistic therapeutic effects and manageable safety profiles in patients with unresectable HCC. [ABSTRACT FROM AUTHOR]

Patients with tumor thrombosis in the portal vein due to hepatocellular carcinoma (HCC) are uncommon, and the majority of these cases is thought to be in an advanced stage with a bad prognosis. The right atrium and the inferior vena cava may be impacted by the intravascular tumor thrombus, with the latter having a bad prognosis. Portal vein involvement is one of the most serious consequences of HCC. For both systemic and locoregional therapy, targeting many pathways in the HCC cascade using a mix of medications and additional modalities like transarterial chemoembolization, transarterial radioembolization, radiation, and hepatic arterial infusion chemotherapy appears to be helpful. Portal vein tumor thrombosis, which affects 35 to 50% of patients, is a strong predictor of poor prognosis due to the higher likelihood of tumor migration into the bloodstream and the subsequent increased risk of recurrence. This case report highlights about a 60-year-old female who presented with HCC with portal vein tumor thrombosis not willing for chemo- and radiotherapy successfully treated with transarterial chemoembolization as a palliative management.

Background: Genetic polymorphisms play a crucial role in predicting treatment efficacy in patients with hepatocellular carcinoma (HCC). This study aims to evaluate the response to Transarterial Chemoembolization (TACE) in relation to the genetic polymorphisms of interleukin 28B (IL28B) and angiopoietin-2 (ANGPT2) in HCC patients. Research design and methods: Prospective cohort study conducted on 104 eligible HCC Egyptian patients who underwent TACE using doxorubicin and lipiodol. Genotyping of the IL28B and ANGPT2 genes was performed with laboratory data analysis. Results: At baseline IL28B rs12979860 genotypes C/T, C/C and T/T appeared in 43.9%, 34.6% and 21.5% while ANGPT2 rs55633437 genotypes C/C, C/A and A/A found in 71.03%, 28.04% and 0.93% of patients respectively. After one month of therapy, 51.4% of patients achieved a complete response. There was a significant difference in relation to IL28B rs12979860 genotypes (p = 0.017) whereas ANGPT2 rs55633437 genotypes (p = 0.432) showed no significant difference in patient response after one month of TACE Conclusion: This study demonstrates the effectiveness of TACE in Egyptian HCC patients, as evidenced by low recurrence rates. Furthermore, the IL28B rs12979860 (C/T) gene may be associated with the efficacy and prognosis of TACE treatment in HCC Egyptian patients. Trial Registration: The trial is registered at ClinicalTrials.gov (CT.gov identifier: NCT05291338) [ABSTRACT FROM AUTHOR]

Hepatocellular carcinoma (HCC) is the third most common cause of cancer-related death worldwide with an average five-year survival rate in the US of 19.6%. With the advent of HBV and HCV treatment and prevention, along with the rising rates of obesity, nonalcoholic fatty liver disease (NAFLD) and metabolic syndrome are set to overtake infectious causes as the most common cause of HCC. While surgical resection and transplantation can be curative when amenable, the disease is most commonly unresectable on presentation, and other treatment approaches are the mainstay of therapy. In these patients, locoregional therapies have evolved as a vital tool in both palliation for advanced disease and as a bridge to surgical resection and transplantation. In this review, we will be exploring the primary locoregional therapies for HCC in patients with NAFLD, including transarterial chemoembolization (TACE), bland transarterial embolization (TAE), transarterial radioembolization (TARE), and percutaneous ablation.

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 and Objectives: This study aimed to evaluate the tumor response relating to and survival benefit of transarterial chemoperfusion (TACP) and transarterial chemoembolization (TACE) in the treatment of patients with unresectable gynecologic tumors who are intolerant of or have a suboptimal response to chemotherapy and radiotherapy. Materials and Methods: Between January 2000 and October 2023, 75 patients diagnosed with gynecologic tumors underwent 213 TACP and 154 TACE procedures. Of these, 33 patients were treated with TACP, 20 were treated with TACE, and 22 received a combination of both therapies. A retrospective evaluation of local tumor response according to Response Evaluation Criteria in Solid Tumors (RECIST) was conducted, and survival rates were determined using the Kaplan–Meier estimator. Results: Of the total 75 patients, 50 (67%) maintained a stable course of disease until the completion of therapy, 10 (13%) had a partial response, 2 (3%) had a complete response following thermal ablation, and 13 (17%) experienced progression. Furthermore, a 6% reduction in the sum of the longest diameters and an 8% reduction in tumor volume were observed. The median overall survival was 16.15 months, while the median progression-free survival was 13.19 months. Conclusions: TACP and TACE are potential treatment options for local tumor control in patients with unresectable gynecologic tumors who are intolerant of or show a poor response to chemotherapy and radiotherapy. However, further investigation and adjustment of treatment protocols are required to improve therapy response and survival outcomes. [ABSTRACT FROM AUTHOR]

To clarify the survival benefit of sequential curative treatment post transcatheter arterial chemoembolization (TACE) for Barcelona Clinic Liver Cancer (BCLC) stage B hepatocellular carcinoma (HCC), we retrospectively analyzed HCC patients at a hospital. From July 2017 to July 2020, 787 treatment-naïve HCC patients underwent initial treatment; 77 (9.8%) meeting inclusion criteria were enrolled. Their initial treatments were TACE only (n = 68, 88.3%) or TACE with other treatments (n = 9, 11.7%). Median survival of the TACE-only group was 30 months. Treatment response was evaluated after 2 or 3 consecutive TACEs for patients (54/68, 79.4%) with available pre-/post-TACE computerized tomography (CT) or magnetic resonance imaging (MRI). Treatment responses was divided into 4 groups: complete (n = 14, 26%, group (Gr) 1), incomplete without new tumor growth (n = 28, 52.0%, Gr2), incomplete with new growth (n = 6, 11%, Gr3), and progression (n = 6, 11%, Gr4). Of Gr2, further treatment after TACE were had radiofrequency ablation (n = 13, Gr2a), TACE (n = 9, Gr2b), other modalities (n = 6, Gr2c. Gr2a's median survival was longer than Gr2b's (> 60 vs. 20 months, p = 0.007). Nine patients in Gr2a (69%, 9/13) achieved a complete response, but none in Gr2b (p = 0.001). Conclusively, in TACE-suitable BCLC stage B HCC patients, a partial response without new tumor growth can serve as an indicator of treatment effectiveness following initial TACE treatment. This can facilitate the selection of appropriate candidates to receive RFA, potentially resulting in improved patient survival. [ABSTRACT FROM AUTHOR]

Interventional radiology is one of the most widely used treatment options for abdominal abnormality. Due to new dose limitations, radiation is a hazard that needs to be considered when choosing the international treatment technique. The aim of this study was to measure the effective/equivalent doses and to investigate the associated factors correlating with the doses during Transarterial Chemoembolization (TACE) and Percutaneous Transhepatic Biliary Drainage (PTBD) for radiologists, technologists and nurses involved with the treatment. This prospective study reports occupational dose per procedure of 57 cases (TACE = 42, PTBD = 15) in a Thailand hospital spanning one year. All staff included in this study wore 30 nanoDot Optically Stimulated Luminescence Dosimeter for measuring doses at 7 bodily locations. The average dose area product and cumulative doses was 151.3 Gy·cm2, 1,185.1 mGy during TACE and 21.3 Gy·cm2, 212.2 mGy during PTBD. The radiation exposure of the radiologists was significantly higher than technologists and nurses (p-value < 0.05). The lead protection equipment was a dose-reducing factor which decreased the dose up to 93%. The present study also contributes to the establishment of an individual dose location report and identifies significant correlations between associated factors and dose values. The left hand (1.2 mSv) and the left eye (1.1 mSv) showed maximum doses during the PTBD procedure. The exceeded dose over the limitation was observed in the left eye. We concluded that the dose feedback was able to increase awareness of the occupation staff. So, dose monitoring, updating education and regular training could be applied simply and effectively to improve skills, while reducing the occupational dose. [ABSTRACT FROM AUTHOR]

Introduction: The research field of artificial intelligence (AI) in medicine and especially in gastroenterology is rapidly progressing with the first AI tools entering routine clinical practice, for example, in colorectal cancer screening. Contrast-enhanced ultrasound (CEUS) is a highly reliable, low-risk, and low-cost diagnostic modality for the examination of the liver. However, doctors need many years of training and experience to master this technique and, despite all efforts to standardize CEUS, it is often believed to contain significant interrater variability. As has been shown for endoscopy, AI holds promise to support examiners at all training levels in their decision-making and efficiency. Methods: In this systematic review, we analyzed and compared original research studies applying AI methods to CEUS examinations of the liver published between January 2010 and February 2024. We performed a structured literature search on PubMed, Web of Science, and IEEE. Two independent reviewers screened the articles and subsequently extracted relevant methodological features, e.g., cohort size, validation process, machine learning algorithm used, and indicative performance measures from the included articles. Results: We included 41 studies with most applying AI methods for classification tasks related to focal liver lesions. These included distinguishing benign versus malignant or classifying the entity itself, while a few studies tried to classify tumor grading, microvascular invasion status, or response to transcatheter arterial chemoembolization directly from CEUS. Some articles tried to segment or detect focal liver lesions, while others aimed to predict survival and recurrence after ablation. The majority (25/41) of studies used hand-picked and/or annotated images as data input to their models. We observed mostly good to high reported model performances with accuracies ranging between 58.6% and 98.9%, while noticing a general lack of external validation. Conclusion: Even though multiple proof-of-concept studies for the application of AI methods to CEUS examinations of the liver exist and report high performance, more prospective, externally validated, and multicenter research is needed to bring such algorithms from desk to bedside.

Background: Accurate detection of Hepatocellular carcinoma (HCC) feeding vessels during transcatheter arterial chemoembolization (TACE) is important for an effective treatment, while limiting non-target embolization. This study aimed to investigate the feasibility and accuracy of pre-TACE three dimensional (3D) CT angiography for tumor-feeding vessels detection compared to DSA. Methods: Sixty-nine consecutive patients referred for TACE from May 2022 to May 2023 were included. (3D) CT images were reconstructed from the pre-TACE diagnostic multiphasic contrast enhanced CT images and compared with non-selective digital subtraction angiography (DSA) images obtained during TACE for detection of HCC feeding vessels. A "Ground truth" made by consensus between observers after reviewing all available pre-TACE CT images, and DSA and CBCT images during TACE to detect the true feeding vessels was the gold standard. Sensitivity, specificity, negative predictive value (NPV), positive predictive value (PPV), accuracy and ROC curve with AUC were calculated for each modality and compared. Results: A total of 136 active HCCs were detected in the 69 consecutive patients included in the study. 185 feeding arteries were detected by 3D CT and DSA and included in the analysis. 3D CT detection of feeding arteries revealed mean sensitivity, specificity, PPV, NPV and accuracy of 91%, 71%, 98%, 36%, and 90%, respectively, with mean AUC = 0.81. DSA detection of feeding arteries revealed mean sensitivity, specificity, PPV, NPV, and accuracy of 80%, 58%, 96.5%, 16.5% and 78%, respectively, with mean AUC = 0.69. Conclusions: Pre-TACE 3D CT angiography has shown promise in improving the detection of HCC feeding vessels compared to DSA. However, further studies are required to confirm these findings across different clinical settings and patient populations. Trial registration: This study was prospectively registered at Clinicaltrials.gov with ID NCT05304572; Date of registration: 2-4-2022. [ABSTRACT FROM AUTHOR]

Background: Portal vein tumor thrombosis (PVTT) commonly occurs in patients with primary liver cancer (PLC). Transarterial chemoembolization (TACE) is a treatment for patients with PLC and PVTT. Some studies have shown that combining TACE therapy with hepatic arterial infusion chemotherapy (HAIC) might improve the survival rate of PLC patients with PVTT. However, few studies have compared the different regimens of PLC with PVTT. We aimed to compare the differences between the oxaliplatin + raltetrexed regimen and FOLFOX regimen. Methods: We divided the 248 patients into two groups. There were 60 patients in the oxaliplatin + ratitetrexed group and 74 patients in the FOLFOX group. The primary endpoints were OS and PFS. The secondary endpoints were ORR and adverse events. We used SPSS software, the Kaplan–Meier method, the t test, and the rank sum test to compare the differences between the two groups. Results: The median OS was 10.82 months in the oxaliplatin + raltitrexed group and 8.67 months in the FOLFOX group. The median PFS time was greater in the oxaliplatin + raltitrexed group (10.0 months) than that in the FOLFOX group (7.1 months). The ORR was greater in the oxaliplatin + raltitrexed group than that in the FOLFOX group (18.3% vs. 13.5%; P = 0.445). The DCR in the oxaliplatin + raltitrexed group was higher than that in the FOLFOX group (70.0% vs. 64.8%; P = 0.529). However, in the subgroup analysis, the difference between them was more significant in the type II PVTT subgroup. The OS was 12.08 months in the oxaliplatin + raltitrexed group and 7.26 months in the FOLFOX group (P = 0.008). The PFS was 11.68 months in the oxaliplatin + raltitrexed group and 6.26 months in the FOLFOX group (P = 0.014). In the right branch of type II PVTT, the OS was 13.54 months in the oxaliplatin + raltitrexed group and 6.89 months in the FOLFOX group (P = 0.015), and the PFS was 13.35 months in the oxaliplatin + raltitrexed group and 6.27 months in the FOLFOX group (P = 0.030). The incidence of adverse reactions was similar between the two groups. Conclusions: Compared with the FOLFOX regimen, the oxaliplatin + raltitrexed chemoembolization regimen had longer OS, PFS time and ORR and DCR and it was safe and tolerable. [ABSTRACT FROM AUTHOR]

Introduction: This study aimed to evaluate the efficacy and safety of atezolizumab combined with bevacizumab (Atez/Bev) compared to lenvatinib (LEN) as first‐line systemic therapy for patients with Barcelona Clinic Liver Cancer (BCLC) stage B hepatocellular carcinoma (HCC) exceeding the up‐to‐seven criteria threshold, who are typically unsuitable for transarterial chemoembolization (TACE). Methods: A retrospective analysis was conducted on 49 consecutive patients with HCC treated at Tokyo Metropolitan Komagome Hospital between May 2018 and October 2023. The patients were divided into two groups: the Atez/Bev group (21 patients) and the LEN group (28 patients). Eligibility criteria included Child‐Pugh A classification, no prior systemic therapy, and ineligibility for resection, ablation, or transplantation. Treatment outcomes were assessed through periodic imaging and laboratory tests, evaluating OS, PFS, ORR, and disease control rate (DCR). Results: Both groups demonstrated comparable baseline characteristics, with a median follow‐up of 15.4 months. No significant difference was observed in OS between the Atez/Bev and LEN groups (median OS: 19.80 vs. 22.20 months, p = 0.763). The median PFS was 10.23 months for Atez/Bev and 7.20 months for LEN (p = 0.343). There were no statistically significant differences in ORR or DCR between the two groups. Common adverse events included elevated AST and ALT levels, with no significant difference in the overall rate of adverse events between the groups. Conclusions: Atez/Bev and LEN demonstrated comparable efficacy and safety as first‐line systemic treatments for patients with BCLC stage B HCC exceeding the up‐to‐seven criteria. Both therapeutic options are viable for this population, though further large‐scale prospective studies are required to confirm these findings. [ABSTRACT FROM AUTHOR]
