RESUMO
BACKGROUND AND AIMS: Molecular classification is a promising tool for prognosis prediction and optimizing precision therapy for HCC. Here, we aimed to develop a molecular classification of HCC based on the fatty acid degradation (FAD) pathway, fully characterize it, and evaluate its ability in guiding personalized therapy. APPROACH AND RESULTS: We performed RNA sequencing (RNA-seq), PCR-array, lipidomics, metabolomics, and proteomics analysis of 41 patients with HCC, in which 17 patients received anti-programmed cell death-1 (PD-1) therapy. Single-cell RNA sequencing (scRNA-seq) was performed to explore the tumor microenvironment. Nearly, 60 publicly available multiomics data sets were analyzed. The associations between FAD subtypes and response to sorafenib, transarterial chemoembolization (TACE), immune checkpoint inhibitor (ICI) were assessed in patient cohorts, patient-derived xenograft (PDX), and spontaneous mouse model ls. A novel molecular classification named F subtype (F1, F2, and F3) was identified based on the FAD pathway, distinguished by clinical, mutational, epigenetic, metabolic, and immunological characteristics. F1 subtypes exhibited high infiltration with immunosuppressive microenvironment. Subtype-specific therapeutic strategies were identified, in which F1 subtypes with the lowest FAD activities represent responders to compounds YM-155 and Alisertib, sorafenib, anti-PD1, anti-PD-L1, and atezolizumab plus bevacizumab (T + A) treatment, while F3 subtypes with the highest FAD activities are responders to TACE. F2 subtypes, the intermediate status between F1 and F3, are potential responders to T + A combinations. We provide preliminary evidence that the FAD subtypes can be diagnosed based on liquid biopsies. CONCLUSIONS: We identified 3 FAD subtypes with unique clinical and biological characteristics, which could optimize individual cancer patient therapy and help clinical decision-making.

Deaths from the majority of cancers are falling globally, but the incidence and mortality from hepatocellular carcinoma (HCC) is increasing in the United Kingdom and in other Western countries. HCC is a highly fatal cancer, often diagnosed late, with an incidence to mortality ratio that approaches 1. Despite there being a number of treatment options, including those associated with good medium to long-term survival, 5-year survival from HCC in the UK remains below 20%. Sex, ethnicity and deprivation are important demographics for the incidence of, and/or survival from, HCC. These clinical practice guidelines will provide evidence-based advice for the assessment and management of patients with HCC. The clinical and scientific data underpinning the recommendations we make are summarised in detail. Much of the content will have broad relevance, but the treatment algorithms are based on therapies that are available in the UK and have regulatory approval for use in the National Health Service.

Background CT-guided high-dose-rate (HDR) brachytherapy (hereafter, HDR brachytherapy) has been shown to be safe and effective for patients with unresectable hepatocellular carcinoma (HCC), but studies comparing this therapy with other local-regional therapies are scarce. Purpose To compare patient outcomes of HDR brachytherapy and transarterial chemoembolization (TACE) in patients with unresectable HCC. Materials and Methods This multi-institutional retrospective study included consecutive treatment-naive adult patients with unresectable HCC who underwent either HDR brachytherapy or TACE between January 2010 and December 2022. Overall survival (OS) and progression-free survival (PFS) were compared between patients matched for clinical and tumor characteristics by propensity score matching. Not all patients who underwent TACE had PFS available; thus, a different set of patients was used for PFS and OS analysis for this treatment. Hazard ratios (HRs) were calculated from Kaplan-Meier survival curves. Results After propensity matching, 150 patients who underwent HDR brachytherapy (median age, 71 years [IQR, 63-77 years]; 117 males) and 150 patients who underwent TACE (OS analysis median age, 70 years [IQR, 63-77 years]; 119 male; PFS analysis median age, 68 years [IQR: 63-76 years]; 119 male) were analyzed. Hazard of death was higher in the TACE versus HDR brachytherapy group (HR, 4.04; P < .001). Median estimated PFS was 32.8 months (95% CI: 12.5, 58.7) in the HDR brachytherapy group and 11.6 months (95% CI: 4.9, 22.7) in the TACE group. Hazard of disease progression was higher in the TACE versus HDR brachytherapy group (HR, 2.23; P < .001). Conclusion In selected treatment-naive patients with unresectable HCC, treatment with CT-guided HDR brachytherapy led to improved OS and PFS compared with TACE. © RSNA, 2024 Supplemental material is available for this article.

Liver transplantation is the curative therapy of choice for patients with early-stage HCC. Locoregional therapies are often employed as a bridge to reduce the risk of waitlist dropout; however, their association with posttransplant outcomes is unclear. We conducted a systematic review using Ovid MEDLINE and EMBASE to identify studies published between database inception and August 2, 2023, which reported posttransplant recurrence-free survival and overall survival among patients transplanted for HCC within Milan criteria, stratified by receipt of bridging therapy. Pooled HRs were calculated for each outcome using the DerSimonian and Laird method for a random-effects model. We identified 38 studies, including 19,671 patients who received and 20,148 patients who did not receive bridging therapy. Bridging therapy was not associated with significant differences in recurrence-free survival (pooled HR: 0.91, 95% CI: 0.77-1.08; I2 =39%) or overall survival (pooled HR: 1.09, 95% CI: 0.95-1.24; I2 =47%). Results were relatively consistent across subgroups, including geographic location and study period. Studies were discordant regarding the differential strength of association by pretreatment tumor burden and pathologic response, but potential benefits of locoregional therapy were mitigated in those who received 3 or more treatments. Adverse events were reported in a minority of studies, but when reported occurred in 6%-15% of the patients. Few studies reported loss to follow-up and most had a risk of residual confounding. Bridging therapy is not associated with improvements in posttransplant recurrence-free or overall survival among patients with HCC within Milan criteria. The risk-benefit ratio of bridging therapy likely differs based on the risk of waitlist dropout.

Transarterial chemoembolization (TACE) and transarterial radioembolization (TARE) are the 2 most used modalities for patients with HCC while awaiting liver transplant. The purpose of this study is to perform a cost-effectiveness analysis comparing TACE and TARE for downstaging (DS) patients with HCC. A cost-effectiveness analysis was performed comparing TACE and TARE in DS HCC over a 5-year time horizon from a payer's perspective. The clinical course, including those who achieved successful DS leading to liver transplant and those who failed DS with possible disease progression, was obtained from the United Network for Organ Sharing. Costs and effectiveness were measured in US dollars and quality-adjusted life years (QALYs). Probabilistic and deterministic sensitivity analyses were performed. TARE achieved a higher effectiveness of 2.51 QALY (TACE: 2.29 QALY) at a higher cost of $172,162 (TACE: $159,706), with the incremental cost-effectiveness ratio of $55,964/QALY, making TARE the more cost-effective strategy. The difference in outcome was equivalent to 104 days (nearly 3.5 months) in compensated cirrhosis state. Probabilistic sensitivity analyses showed that TARE was more cost-effective in 91.69% of 10,000 Monte Carlo simulations. TARE was more effective if greater than 48.2% of patients who received TACE or TARE were successfully downstaged (base case: 74.6% from the pooled analysis of multiple published cohorts). TARE became more cost-effective when the cost of TACE exceeded $4,831 (base case: $12,722) or when the cost of TARE was lower than $43,542 (base case: $30,609). Subgroup analyses identified TARE to be the more cost-effective strategy if the TARE cohort required 1 fewer locoregional therapy than the TACE cohort. TARE is the more cost-effective DS strategy for patients with HCC exceeding Milan criteria compared to TACE.

BACKGROUND: Hepatocellular carcinoma (HCC) is a common malignant tumor, and glutamine is vital for tumor cells. The role of glutamine transporter SLC1A5 in tumor progression and transarterial chemoembolization (TACE) efficacy is under study. This research seeks to determine the impact of SLC1A5 expression on the prognosis and TACE efficacy of HCC and elucidate its mechanisms. METHODS: SLC1A5 expression in HCC, correlation with patient outcomes, and response to TACE were studied in an open access liver cancer dataset and confirmed in our cohort. Additionally, the correlation between SLC1A5 expression and hypoxia, angiogenesis and immune infiltration was analyzed and verified by immunohistochemistry, immunofluorescence and transcriptome sequencing. Liver cancer cell lines with SLC1A5 expression knockdown or overexpression were constructed, and cell proliferation, colony formation, apoptosis, migration and drug sensitivity as well as in vivo xenograft tumor were measured. A gene set enrichment analysis was conducted to determine the signaling pathway influenced by SLC1A5, and a western blot analysis was performed to detect protein expression alterations. RESULTS: SLC1A5 expression was higher in HCC tissue and associated with poor survival and TACE resistance. Hypoxia could stimulate the upregulation of glutamine transport, angiogenesis and SLC1A5 expression. The SLC1A5 expression was positively correlated with hypoxia and angiogenesis-related genes, immune checkpoint pathways, macrophage, Tregs, and other immunosuppressive cells infiltration. Knockdown of SLC1A5 decreased proliferation, colony formation, and migration, but increased apoptosis and increased sensitivity to chemotherapy drugs. Downregulation of SLC1A5 resulted in a decrease in Vimentin and N-cadherin expression, yet an increase in E-cadherin expression. Upregulation of SLC1A5 increased Vimentin and N-cadherin expression, while decreasing E-cadherin. Overexpression of ß-catenin in SLC1A5-knockdown HCC cell lines could augment Vimentin and N-cadherin expression, suppress E-cadherin expression, and increase the migration and drug resistance. CONCLUSIONS: Elevated SLC1A5 was linked to TACE resistance and survival shortening in HCC patients. SLC1A5 was positively correlated with hypoxia, angiogenesis, and immunosuppression. SLC1A5 may mediate HCC cell migration and drug resistance via Epithelial-mesenchymal transition (EMT) pathway.

BACKGROUND: Combination treatment with transcatheter arterial chemoembolization (TACE), lenvatinib, and anti-programmed death-1 (anti-PD-1) antibodies (triple therapy) has a high rate of tumor response and converted resection for initially unresectable hepatocellular carcinoma (uHCC) patients. This study aimed to assess the outcomes of salvage surgery in uHCC patients after conversion therapy with triple therapy. METHODS: uHCC patients who met the criteria for hepatectomy after receiving triple therapy as first-line treatment were eligible for inclusion in this study. The overall survival (OS) and progression-free survival (PFS) rates in patients who received salvage surgery (SR group) and those who did not (non-SR group) were compared. RESULTS: Of the 144 patients assessed, 91 patients underwent salvage surgery and 53 did not. The OS rates in the SR group were significantly better than those in the non-SR group. The 1- and 2-year OS rates in the SR group were 92.0% and 79.9%, respectively, whereas those in the non-SR group were 85.5% and 39.6 %, respectively (p = 0.007); however, there was no significant difference in the PFS rates. Upon further stratification, OS and PFS were significantly better in the SR group than in the non-SR group in patients who were assessed as partial responses (PR), while there was no significant difference in patients who were assessed as complete response (CR). CONCLUSIONS: Salvage surgery is recommended and is associated with a favorable prognosis for uHCC patients who were assessed as PR after conversion therapy, however it may not be necessary for uHCC if CR was achieved.

BACKGROUND: Treatment of unresectable colorectal liver metastases (UCRLM) includes locoregional and systemic therapy. A comprehensive analysis capturing long-term outcomes of these treatment options has not been performed. OBJECTIVE: A systematic review and meta-analysis was performed to calculate pooled outcomes of hepatic artery infusion with systemic chemotherapy (HAI-S), transarterial chemoembolization with systemic chemotherapy (TACE-S), transarterial radioembolization with systemic chemotherapy (TARE-S), doublet (FOLFOX, FOLFIRI), and triplet chemotherapy (FOLFOXIRI). METHODS: Outcomes included overall survival (OS), progression-free survival (PFS), rate of conversion to resection (CTR), and response rate (RR). RESULTS: A total of 32, 7, 9, and 14 publications were included in the HAI-S, TACE-S, and TARE-S chemotherapy arms. The 6/12/24/36-month OS estimates for HAI-S, TACE-S, TARE-S, FOLFOX, FOLFIRI, and FOLFOXIRI were 97%/80%/54%/35%, 100%/83%/40%/14%, 82%/61%/34%/21%, 96%/83%/53%/36%, and 96%/93%/72%/55%. Similarly, the 6/12/24/36-month PFS estimates were 74%/44%/19%/14%, 66%/20%/9%/3%, 57%/23%/10%/3%, 69%/30%/12%/7%, and 88%/55%/18%/11%. The corresponding CTR and RR rates were 31, 20%, unmeasurable (TARE-S), 35, 53; and 49, 45, 45, 50, 80%, respectively. The majority of chemotherapy studies included first-line therapy and liver-only metastases, whereas most HAI-S studies were pretreated. On subgroup analysis in first-line setting with liver-only metastases, the HAI-S arm had comparable outcomes to FOLFOXIRI and outperformed doublet chemotherapy regimens. Although triplet chemotherapy appeared to outperform other arms, high toxicity and inclusion of potentially resectable patients must be considered while interpreting results. CONCLUSIONS: HAI-S and multiagent chemotherapy are effective therapies for UCRLM. To make definitive conclusions, a randomized trial with comparable patient characteristics and line of therapy will be required. The upcoming EA2222 PUMP trial may help to address this question.

Despite the emergence of various treatment strategies for rectal cancer based on neoadjuvant chemoradiotherapy, there is currently a lack of reliable biomarkers to determine which patients will respond well to neoadjuvant chemoradiotherapy. Through collecting hematological and biochemical parameters data of patients prior to receiving neoadjuvant chemoradiotherapy, we evaluated the predictive value of systemic inflammatory indices for pathological response and prognosis in rectal cancer patients. We found that baseline GRIm-Score was an independent predictor for MPR in rectal cancer patients. However, no association was observed between several commonly systemic inflammation indices and long-term outcome.

INTRODUCTION: The treatment of hepatocellular carcinoma (HCC) with transarterial chemoembolization (TACE) and lenvatinib individually has shown favorable outcomes, but there is currently no meta-analysis based on randomized controlled trials (RCTs) to investigate the efficacy and safety of this combined treatment for HCC. The aim of this study was to identify the efficacy and safety of TACE plus lenvatinib for the treatment of HCC. METHODS: A systematic search of MEDLINE (via PubMed), the Cochrane Library, EMBASE, and the Web of Science was conducted on July 31, 2023. RCTs evaluating the efficacy and safety of TACE in combination with lenvatinib for the treatment of HCC were included. The risk of bias in the included studies was assessed using the Risk of Bias 2 tool. Outcome measures such as objective response rate (ORR), complete remission (CR), progression-free survival (PFS), overall survival (OS), and safety parameters were extracted from the included studies. Binary outcomes were analyzed using odds ratio (OR), risk ratio, or hazard ratio (HR), while continuous variables were analyzed using mean difference (MD) or standardized MD in RStudio. The quality of the evidence was graded using the GRADE approach. Heterogeneity was considered significant when the I-squared was 50% or less. RESULTS: Five RCTs involving 638 patients were included. The meta-analysis revealed that patients in the TACE plus lenvatinib group had a significantly higher mean ORR compared to the control group (OR: 3.65, 95% confidence interval [CI]: 2.50-5.32, fixed-effects model; OR: 3.58, 95% CI: 2.45-5.24, random-effects model, I2 = 0, moderate quality). Specifically, 40.9% of patients in the TACE plus lenvatinib group achieved a PR, which was significantly higher than the control group (OR: 3.51, 95% CI: 2.41-5.13, fixed-effects model; OR: 3.46, 95% CI: 2.36-5.07, random-effects model, I2 = 0, moderate quality). The HR for OS was 0.47 (95% CI: 0.35-0.62, fixed-effects model and random-effects model, I2 = 0, moderate quality). The meta-analysis revealed that the TACE plus lenvatinib group had a significantly higher total adverse effects rate than the control group (OR: 1.86, 95% CI: 1.01-3.43, fixed-effects model; OR: 1.85, 95% CI: 1.00-3.43, random-effects model, I2 = 0, moderate quality). CONCLUSION: Our study suggests that the combination of TACE and lenvatinib in the treatment of HCC has shown promising results, with extended OS and improved ORR.

BACKGROUND: The safety and efficacy of transarterial chemoembolization plus molecular targeted therapy (MTT) combined with immune checkpoint inhibitors (ICIs) in primary liver cancer have been demonstrated. However, the evidence for TACE plus MTT combined with ICIs in the treatment of recurrent hepatocellular carcinoma (RHCC) is limited. Given the excellent performance of this combination regimen in primary liver cancer, it is necessary to evaluate the efficacy of TACE plus MTT combined with ICIs in RHCC. METHODS: A total of 88 patients with RHCC treated with TACE plus MTT combined with camrelizumab (TACE-TC group, n = 46) or TACE plus MTT (TACE-T group, n = 42) were retrospectively collected and analyzed. In this study, we evaluated the effectiveness and safety of combination therapy for patients with RHCC by analyzing tumor response, progression-free survival (PFS), overall survival (OS), laboratory biochemical indices, and adverse events (AEs). RESULTS: TACE-TC was superior to TACE-T in PFS (14.0 vs. 8.9 months, p = 0.034) and OS (31.1 vs. 20.2 months, p = 0.009). Moreover, TACE-TC achieved more preferable benefits with respect to disease control rate (89.1% vs. 71.4%, p = 0.036) and objective response rate (47.8% vs. 26.2%, p = 0.036) compared with TACE-T in patients with RHCC. Compared with the TACE-T group, the AFP level in the TACE-TC group decreased more significantly after 3 months of treatment. Multivariate analysis showed that treatment option was a significant predictor of OS and PFS, while the portal vein tumor thrombus and interval of recurrence from initial treatment were another prognostic factor of PFS. There was no significant difference between the TACE-TC and TACE-T groups for Grade 3-4 adverse events. CONCLUSIONS: A combination therapy of TACE, MTT, and camrelizumab significantly improved tumor response and prolonged survival duration, showing a better survival prognosis for RHCC patients.

BACKGROUND: Patients with hepatocellular carcinoma (HCC) who undergo transarterial chemoembolization (TACE) may have varied outcomes based on their liver function and tumor burden diversity. This study aims to assess the prognostic significance of the tumor burden score (TBS) in these patients and develop a prognostic model for their overall survival. METHODS: The study involved a retrospective analysis of 644 newly diagnosed HCC patients undergoing TACE treatment. The individuals were assigned randomly to a training cohort (n = 452) and a validation cohort (n = 192). We utilized a multivariate Cox proportional risk model to identify independent preoperative predictive factors. We then evaluated model performance using the area under the curve (AUC), consistency index (c-index), calibration curve, and decision curve analysis (DCA) methods. RESULTS: The multivariate analysis revealed four prognostic factors associated with overall survival: Tumor Burden Score, Tumor Extent, Types of portal vein invasion (PVI), and Child-Pugh score. The total score was calculated based on these factors. The model demonstrated strong discriminative ability with high AUC values and c-index, providing high net clinical benefits for patients. Based on the model's scoring results, patients were categorized into high, medium, and low-risk groups. These results were validated in the validation cohort. CONCLUSIONS: The tumor burden score shows promise as a viable alternative prognostic indicator for assessing tumor burden in cases of HCC. The new prognostic model can place patients in one of three groups, which will estimate their individual outcomes. For high-risk patients, it is suggested to consider alternative treatment options or provide the best supportive care, as they may not benefit significantly from TACE treatment.

BACKGROUND: The purpose of this propensity score matching (PSM) analysis was to compare the effects of preoperative transcatheter arterial chemoembolization (TACE) and non-TACE on the long-term survival of patients who undergo radical hepatectomy. METHODS: PSM analysis was performed for 387 patients with hepatocellular carcinoma (HCC) (single > 3 cm or multiple) who underwent radical resection of HCC at our centre from January 2011 to June 2018. The patients were allocated to a preoperative TACE group (n = 77) and a non-TACE group (n = 310). The main outcome measures were progression-free survival (PFS) and overall survival (OS) since the treatment date. RESULTS: After PSM, 67 patients were included in each of the TACE and non-TACE groups. The median PFS times in the preoperative TACE and non-TACE groups were 24.0 and 11.3 months, respectively (p = 0.0117). The median OS times in the preoperative TACE and non-TACE groups were 41.5 and 29.0 months, respectively (p = 0.0114). Multivariate Cox proportional hazard regression analysis revealed that preoperative TACE (hazard ratio, 1.733; 95% CI, 1.168-2.570) and tumour thrombosis (hazard ratio, 0.323; 95% CI, 0.141-0.742) were independent risk factors significantly associated with OS. CONCLUSIONS: Preoperative TACE is related to improving PFS and OS after resection of HCC. Preoperative TACE and tumour thrombus volume were also found to be independent risk factors associated with OS.

BACKGROUND: The prognostic significance of the CRAFITY score (CRP and AFP in ImmunoTherapY) has been demonstrated in hepatocellular carcinoma (HCC) patients receiving immunotherapy. The purpose of this study was to investigate the utility and the predictive value of CRAFITY score in HCC after transarterial chemoembolization (TACE) in combination with tyrosine kinase inhibitors (TKIs) and immunotherapy. MATERIALS AND METHODS: Data from patients with advanced HCC treated with TACE plus TKIs and PD-1 inhibitor from January 2019 to June 2022 were collected and analyzed retrospectively. Patients with AFP ≥ 100 ng/mL and those with CRP ≥ 1 mg/dL were assigned a CRAFITY score of 1 point. Patients were divided into three groups according to their CRAFITY score (CRAFITY-low, 0 points; CRAFITY-intermediate, 1 point; and CRAFITY-high, 2 points). The differences in overall survival (OS), progression-free survival (PFS) and adverse events (AEs) were compared among the three groups. Tumor response was evaluated at 3, 6 and 12 months after the first combination treatment. Risk factors for OS and PFS were assessed. RESULTS: A total of 70 patients were included. The patients were assigned CRAFITY scores of 0 points (CRAFITY-low, n = 25 [35.71%]), 1 point (CRAFITY-intermediate, n = 29 [41.42%]), and 2 points (CRAFITY-high, n = 16 [22.81%]). Multivariate analysis showed that lower CRAFITY score was an independent factor for the improved OS (P =.045) and PFS (P <.001). TACE session was also associated with the OS (P =.048) in the multivariate analysis. The CRAFITY-low cohort achieved a higher objective response rate (ORR) at the 3-month evaluation of tumor response. However, there was no significant difference in ORR and disease control rate (DCR) observed at the 6-month follow-up. DCR showed a statistically significant difference among three groups during the 12-month follow-up period. The percentage of patients with protein urea was highest in the CRAFITY-high group. No significance differences were observed in grade ≥ 3 AEs in three groups. CONCLUSION: The CRAFITY score is simple and could be useful for predicting treatment outcomes, tumor response and AEs of the HCC patients receiving TACE plus TKIs and PD-1 inhibitor therapy.

BACKGROUNDS: To compare the efficacy and safety of transcatheter arterial chemoembolization (TACE) combined Lenvatinib plus Camrelizumab (TLC) in unresectable hepatocellular carcinoma (uHCC) with those of TACE alone . METHODS: A retrospective analysis was performed on 222 patients with uHCC who were treated between September 2013 and Jun 2023. One group received TACE + lenvatinib + camrelizumab (TLC) (n = 97) and another group received TACE alone (n = 151). Efficacy and safety were compared after propensity score matching between the TLC and TACE groups. RESULTS: After propensity matching, the TLC group had higher objective response rate (ORR) (88.6% vs. 28.6%, P < 0.001), disease control rate (DCR) (94.3%% vs. 72.9%, P < 0.001), and conversion rates before and after propensity matching were 44.1% and 41.4%, respectively, compared with the TACE group. The median progression free survival (PFS) was longer in the TLC group than in the TACE group (12.7 vs. 6.1 months, P = 0.005). The median overall survival (OS) was longer in the TLC group than in the TACE group (19.4 vs. 13.0 months, P = 0.023). Cox multivariate analysis with different modes of adjustment showed that treatment was an independent influencing factor of PFS and OS. The interaction analysis showed that cirrhosis and Child-Pugh stage an interactive role in the PFS of different treatment. Decreased AFP after treatment portends higher ORR and DCR. CONCLUSION: TACE combined Lenvatinib plus Camrelizumab regimen was safe and superior to TACE alone in improving PFS, OS, and tumor response rates for unresectable recurrent HCC patients.

BACKGROUND: The role of adjuvant transcatheter arterial chemoembolization (TACE) following repeated resection/ablation for recurrent hepatocellular carcinoma (HCC) remains uncertain. The aim of this study was to assess the effectiveness of adjuvant TACE following repeated resection or ablation in patients with early recurrent HCC. METHODS: Information for patients who underwent repeated surgery or radiofrequency ablation (RFA) for early recurrent HCCs (< 2 years) at our institution from January 2017 to December 2020 were collected. Patients were divided into adjuvant TACE and observation groups according to whether they received adjuvant TACE or not. The recurrence-free survival (RFS) and overall survival (OS) were compared between the two groups before and after propensity score matching (PSM). RESULTS: Of the 225 patients enrolled, the median time of HCC recurrence was 11 months (IQR, 6-16 months). After repeated surgery or radiofrequency ablation (RFA) for recurrent tumors, 45 patients (20%) received adjuvant TACE while the remaining 180 (80%) didn't. There were no significant differences in RFS (P = 0.325) and OS (P = 0.072) between adjuvant TACE and observation groups before PSM. There were also no significant differences in RFS (P = 0.897) and OS (P = 0.090) between the two groups after PSM. Multivariable analysis suggested that multiple tumors, liver cirrhosis, and RFA were independent risk factors for the re-recurrence of HCC. CONCLUSION: Adjuvant TACE after repeated resection or ablation for early recurrent HCCs was not associated with a long-term survival benefit in this single-center cohort.

BACKGROUND: In China, both percutaneous microwave/radiofrequency ablation liver partition plus portal vein embolization (PALPP) and transarterial chemoembolization (TACE) plus portal vein embolization (PVE) have been utilized in planned hepatectomy. However, there is a lack of comparative studies on the effectiveness of these two techniques for cases with insufficient future liver remnant (FLR). METHODS: Patients were categorized into either the PALPP group or the TACE + PVE group. Clinical data, including FLR growth rate, complications, secondary resection rate, and overall survival rate, were compared and analyzed for both groups retrospectively. RESULTS: Between December 2014 and October 2021, a total of 29 patients underwent TACE + PVE (n = 12) and PALPP (n = 17). In the TACE + PVE group, 7 patients successfully underwent two-stage hepatectomy, while in the PALPP group, 13 patients underwent the procedure (two-stage resection rate: 58.3% vs. 76.5%, P = 0.42). There were no significant differences in postoperative complications of one-stage procedures (11.8% vs. 8.3%, P > 0.05) and second-stage resection complication (0% vs. 46.2%, P = 0.05) between the TACE + PVE and PALPP groups. However, the PALPP group demonstrated a shorter time to FLR volume growth for second-stage resection (18.5 days vs. 66 days, P = 0.001) and KGR (58.5 ml/week vs. 7.7 ml/week, P = 0.001). CONCLUSIONS: Compared with TACE + PVE, PALPP results in a more significant increase in FLR volume and a higher rate of two-stage resection without increasing postoperative complications.

BACKGROUND & AIMS: Our retrospective study has suggested encouraging outcomes of lenvatinib combined with PD-1 inhibitor and transarterial chemoembolization (TACE) on advanced hepatocellular carcinoma (HCC). This phase II trial was conducted to prospectively investigate the efficacy and safety of lenvatinib, sintilimab (a PD-1 inhibitor) plus TACE (Len-Sin-TACE) in patients with advanced stage HCC. METHODS: This was a single-arm phase II trial. Patients with BCLC stage C HCC were recruited. They received lenvatinib (bodyweight ≥60 kg, 12 mg; bodyweight <60 kg, 8 mg) orally once daily, sintilimab (200 mg) intravenously once every 3 weeks, and on demand TACE. The primary endpoint was progression-free survival (PFS) per mRECIST. RESULTS: Thirty patients were enrolled. The primary endpoint was met with a median PFS of 8.0 (95% confidence interval [CI]: 6.1-9.8) months per mRECIST, which was the same as that per RECIST 1.1. The objective response rate was 60.0% per mRECIST and 30.0% per RECIST 1.1. The disease control rate was 86.7% per mRECIST/RECIST 1.1. The median duration of response was 7.4 (95% CI: 6.6-8.2) months per mRECIST (n = 18) and 4.3 (95% CI: 4.0-4.6) months per RECIST 1.1 (n = 9). The median overall survival was 18.4 (95% CI: 14.5-22.3) months. Treatment-related adverse events (TRAEs) occurred in 28 patients (93.3%) and grade 3 TRAEs were observed in 12 patients (40.0%). There were no grade 4/5 TRAEs. CONCLUSIONS: Len-Sin-TACE showed promising antitumour activities with a manageable safety profile in patients with advanced stage HCC. The preliminary results need to be further evaluated with phase III randomized trials.

OBJECTIVES: To determine the safety and efficacy of transcatheter arterial chemoembolization with CalliSpheres® beads loaded with arsenic trioxide (CBATO-TACE) in the first-line treatment of patients with large (5 cm ≤ maximum diameter < 10 cm) or huge (maximum diameter ≥ 10 cm) hepatocellular carcinoma (HCC). METHODS: Patients were randomly allocated to the CBATO-TACE group and the conventional transcatheter arterial chemoembolization (cTACE) group. The primary endpoint was progression-free survival (PFS). The secondary endpoint was overall survival (OS), treatment response, and treatment-related adverse events (TRAEs). The extrahepatic collateral arteries, liver function, and liver fibrosis after the first TACE were also evaluated. RESULTS: From September 2018 to September 2020, a total of 207 patients who underwent TACE were consecutively enrolled in this study. The median PFS was 9.5 months (range: 8.0 - 11.0) in the CBATO group, which was significantly longer than that in the cTACE group (6.0 months, range: 4.0-6.0) (p < 0.0001). Patients in the CBATO group had a median OS of 22 months (range: 20.0 - 27.0) compared with 16 months (range: 15.0 - 20.0) in the cTACE group (p = 0.0084). The most common TRAEs were fever (p = 0.043), and nausea and vomiting (p = 0.002), which were more observed in the cTACE group. In addition, the progressive disease time, pulmonary metastasis rate (p = 0.01), the mean number of extrahepatic collateral arteries (p = 0.01), and average number of TACE sessions (p = 0.025) were significantly decreased in the CBATO group. CONCLUSIONS: CBATO-TACE achieved better therapeutic outcomes and similar safety profile compared to cTACE in large or huge HCC patients. Furthermore, CBATO-TACE was able to reduce extrahepatic collateral arteries production and extrahepatic lung metastasis. CLINICAL RELEVANCE STATEMENT: Our study showed that CalliSpheres® beads loaded with arsenic trioxide (CBATO-TACE) were effective and safe for the treatment of large and giant HCC. In addition, CBATO-TACE can reduce lateral hepatic branch artery formation and extrahepatic pulmonary metastasis, which provides a new treatment approach for unresectable HCC. KEY POINTS: ⢠We compare long-term efficacy and safety of transcatheter arterial chemoembolization with CalliSpheres® beads loaded with arsenic trioxide (CBATO-TACE) and conventional transcatheter arterial chemoembolization (cTACE) in patients with large (5 cm ≤ maximum diameter < 10 cm) or huge HCC (maximum diameter ≥ 10 cm). ⢠Compared with cTACE, CBATO-TACE significantly improved therapeutic outcomes, overall survival, and progression-free survival in patients with large or huge HCC. The safety assessment suggested that CBATO-TACE is a safe treatment that improves the quality of life and has good treatment adherence.

OBJECTIVE: To develop and validate a risk scoring scale model (RSSM) for stratifying prognostic risk after intra-arterial therapies (IATs) for hepatocellular carcinoma (HCC). METHODS: Between February 2014 and October 2022, 2338 patients with HCC who underwent initial IATs were consecutively enrolled. These patients were divided into training datasets (TD, n = 1700), internal validation datasets (ITD, n = 428), and external validation datasets (ETD, n = 200). Five-years death was used to predict outcome. Thirty-four clinical information were input and five supervised machine learning (ML) algorithms, including eXtreme Gradient Boosting (XGBoost), Categorical Gradient Boosting (CatBoost), Gradient Boosting Decision Tree (GBDT), Light Gradient Boosting Machine (LGBT), and Random Forest (RF), were compared using the areas under the receiver operating characteristic (AUC) with DeLong test. The variables with top important ML scores were used to build the RSSM by stepwise Cox regression. RESULTS: The CatBoost model achieved the best discrimination when 12 top variables were input, with the AUC of 0.851 (95% confidence intervals (CI), 0.833-0.868) for TD, 0.817 (95%CI, 0.759-0.857) for ITD, and 0.791 (95%CI, 0.748-0.834) for ETD. The RSSM was developed based on the immune checkpoint inhibitors (ICI) (hazard ratios (HR), 0.678; 95%CI 0.549, 0.837), tyrosine kinase inhibitors (TKI) (HR, 0.702; 95%CI 0.605, 0.814), local therapy (HR, 0.104; 95%CI 0.014, 0.747), response to the first IAT (HR, 4.221; 95%CI 2.229, 7.994), tumor size (HR, 1.054; 95%CI 1.038, 1.070), and BCLC grade (HR, 2.375; 95%CI 1.950, 2.894). Kaplan-Meier analysis confirmed the role of RSSM in risk stratification (p < 0.001). CONCLUSIONS: The RSSM can stratify accurately prognostic risk for HCC patients received IAT. On the basis, an online calculator permits easy implementation of this model. CLINICAL RELEVANCE STATEMENT: The risk scoring scale model could be easily implemented for physicians to stratify risk and predict prognosis quickly and accurately, thereby serving as a more favorable tool to strengthen individualized intra-arterial therapies and management in patients with unresectable hepatocellular carcinoma. KEY POINTS: ⢠The Categorical Gradient Boosting (CatBoost) algorithm achieved the optimal and robust predictive ability (AUC, 0.851 (95%CI, 0.833-0.868) in training datasets, 0.817 (95%CI, 0.759-0.857) in internal validation datasets, and 0.791 (95%CI, 0.748-0.834) in external validation datasets) for prediction of 5-years death of hepatocellular carcinoma (HCC) after intra-arterial therapies (IATs) among five machine learning models. ⢠We used the SHapley Additive exPlanations algorithms to explain the CatBoost model so as to resolve the black boxes of machine learning principles. ⢠A simpler restricted variable, risk scoring scale model (RSSM), derived by stepwise Cox regression for risk stratification after intra-arterial therapies for hepatocellular carcinoma, provides the potential forewarning to adopt combination strategies for high-risk patients.
