Improvements in advanced hepatocellular carcinoma to repeat implementation of primary protocol after cancer progression occurs following sequential systemic therapy and a clinical trial: A case report.

INTRODUCTION: Systemic therapy is recommended for patients with advanced hepatocellular carcinoma (aHCC). However, drug resistance occurs over time when patients receive systemic therapy, resulting in cancer progression. Due to the lack of relevant clinical trials, optimizing subsequent treatments after cancer progression remains elusive. PATIENT CONCERNS: A 52-year-old male patient presented with epigastric discomfort and fatigue for almost 1 month with a past history of chronic hepatitis B virus infection for 30 years. DIAGNOSIS: Based on the patient's performance status, tumor status assessed by computed tomography, liver function, he was diagnosed with HCC at BCLC stage C. INTERVENTIONS AND OUTCOMES: He first received transarterial chemoembolization (TACE) combined with sintilimab and lenvatinib as first-line treatment and experienced 10-month progression-free survival. After cancer progression, the patient participated in a clinical trial of ABSK-011, a novel fibroblast growth factor receptor 4 inhibitor, with a frustrating result. Then, the patient underwent TACE and received sintilimab plus lenvatinib again. Surprisingly, the tumor had a partial response, and the patient's serum alpha-fetoprotein returned to normal. LESSONS: The combined treatment of TACE plus systemic therapy might be an appropriate subsequent treatment.

Options and survival benefits of conversion therapy for unresectable hepatocellular carcinoma.

In the study by Wu et al, patients with unresectable hepatocellular carcinoma were subjected to transarterial chemoembolization (TACE) as a conversion therapy in order to render their tumors suitable for resection. A nomogram was devised and shown to be effective in predicting the survival of these patients. Generalization of the results, however, is questionable since the study subjects consisted of patients who had resection after TACE while excluding patients with the same disease but not suitable for TACE. Immunotherapy can be considered to be an option for conversion therapy. However, markers for determining responses to a conversion therapy and for guiding the decision between TACE and sequential immunotherapy have been lacking. The question of whether effective conversion therapy can truly enhance overall survival remains unanswered.

The role of adjuvant transcatheter arterial chemoembolization following repeated curative resection/ablation for hepatocellular carcinoma with early recurrence: a propensity score matching analysis.

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.

Comparative Study of the Short-Term Efficacy and Safety between DEB-TACE and C-TACE in the Treatment of Unresectable Hepatocellular Carcinoma, a Retrospective Study.

Background: This is a retrospective study aimed at comparing the clinical efficacy and safety between drug-eluting bead transcatheter arterial chemoembolization (DEB-TACE) and conventional TACE (C-TACE) in the treatment of unresectable hepatocellular carcinoma. Methods: From July 2019 to April 2021, we enrolled 282 patients with unresectable hepatocellular carcinoma who were admitted to our hospital, of which 179 and 103 were in the DEB-TACE and C-TACE groups, respectively. General information was collected, and treatment effects were evaluated following the modified Response Evaluation Criteria in Solid Tumors. To compare the indexes of liver and kidney function, routine blood and coagulation were collected before treatment, and 1 day, 1 month, 3 months, and 6 months postoperatively. Postoperative adverse reactions (ie, fever, nausea, vomiting, anorexia, abdominal pain) were recorded to evaluate the safety of treatment. The two groups' progression-free survival and overall survival were also calculated to assess the treatment effect. Results: Preoperatively, the bilirubin, transaminase, and absolute neutrophil values between the two groups were not statistically significant (P > .05). At 1 month postoperatively, the absolute neutrophil values were significantly higher in the DEB-TACE group than those in the C-TACE group (P < .05). At 3 months postoperatively, AST, total bilirubin, and direct bilirubin levels were significantly elevated in the DEB-TACE group (P < .05), compared with the C-TACE group. However, at 6 months postoperatively, total and direct bilirubin levels in the C-TACE group were higher than those in the DEB-TACE group, showing a statistically significant difference (P < .05). For patients undergoing DEB-TACE, the survival risk was lower compared to those undergoing C-TACE. The survival risk of patients undergoing DEB-TACE was lower than that of C-TACE within 20 months postoperatively. The survival risk of patients undergoing DEB-TACE was lower than that of patients undergoing C-TACE. Conclusion: DEB-TACE may be superior to C-TACE in terms of safety and efficacy in the treatment of unresectable hepatocellular carcinoma.

Efficacy and safety of transarterial chemoembolization combined with targeted therapy and immunotherapy versus with targeted monotherapy in unresectable hepatocellular carcinoma: A systematic review and meta-analysis.

BACKGROUND AND OBJECTIVE: The application of transarterial chemoembolization (TACE) in combination with targeted therapy and immunotherapy (TACE-T-I) for unresectable hepatocellular carcinoma (HCC) has gained increasing attention. However, there are variations in the efficacy and safety outcomes between TACE-T-I versus TACE combined with targeted drugs (TACE-T). This study aims to systematically evaluate the efficacy and safety of TACE-T-I versus TACE-T in unresectable HCC. METHODS: PubMed, Embase, Cochrane Library, and Web of Science databases were searched from inception to August 21, 2023, for comparative studies on TACE-T-I versus TACE-T for unresectable HCC. Outcome measures included overall survival (OS), progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR) and the incidence of treatment-related adverse events (TRAEs). OS was the primary outcome of this study. Weighted mean difference (WMD) or hazard ratio (HR) was used as the pooled statistic for OS and PFS. Relative risk (RR) was employed as the pooled statistic for ORR, DCR and the incidence of TRAEs. And 95% confidence intervals (CIs) were calculated for all effect measures. Data analysis was conducted using Stata 14.0 software. RESULTS: The meta-analysis included 14 studies with 2144 patients. The pooled results showed that compared with patients in the TACE-T group, patients in the TACE-T-I group had higher ORR (RR = 1.61; 95%CI: 1.38-1.89) and DCR (RR = 1.17; 95%CI: 1.09-1.26). Patients in the TACE-T-I group experienced prolonged PFS (WMD = 3.08; 95%CI: 2.63-3.53) and OS (WMD = 5.76; 95%CI: 4.68-6.84). And the risk of disease progression (HR = 0.45; 95%CI: 0.37-0.55) and death (HR = 0.43; 95%CI: 0.38-0.49) was lower in the TACE-T-I group. Common TRAEs included fever, pain, abdominal pain, nausea, vomiting, elevated ALT, elevated AST, hypertension, hand-foot syndrome, proteinuria, and diarrhea. The incidence and severity of TRAEs in the TACE-T-I group were similar to those in the TACE-T group, with no significant differences (P > .05). CONCLUSION: Current evidence suggests that, on the basis of TACE combined with targeted therapy, the addition of immunotherapy provides better clinical efficacy and survival benefits for unresectable HCC patients, with good tolerability.

Inhibition of the transmembrane transporter ABCB1 overcomes resistance to doxorubicin in patient-derived organoid models of HCC.

BACKGROUND: Transarterial chemoembolization is the first-line treatment for intermediate-stage HCC. However, the response rate to transarterial chemoembolization varies, and the molecular mechanisms underlying variable responses are poorly understood. Patient-derived hepatocellular carcinoma organoids (HCCOs) offer a novel platform to investigate the molecular mechanisms underlying doxorubicin resistance. METHODS: We evaluated the effects of hypoxia and doxorubicin on cell viability and cell cycle distribution in 20 patient-derived HCCO lines. The determinants of doxorubicin response were identified by comparing the transcriptomes of sensitive to resistant HCCOs. Candidate genes were validated by pharmacological inhibition. RESULTS: Hypoxia reduced the proliferation of HCCOs and increased the number of cells in the G0/G1 phase of the cell cycle, while decreasing the number in the S phase. The IC50s of the doxorubicin response varied widely, from 29nM to >1µM. Doxorubicin and hypoxia did not exhibit synergistic effects but were additive in some HCCOs. Doxorubicin reduced the number of cells in the G0/G1 and S phases and increased the number in the G2 phase under both normoxia and hypoxia. Genes related to drug metabolism and export, most notably ABCB1, were differentially expressed between doxorubicin-resistant and doxorubicin-sensitive HCCOs. Small molecule inhibition of ABCB1 increased intracellular doxorubicin levels and decreased drug tolerance in resistant HCCOs. CONCLUSIONS: The inhibitory effects of doxorubicin treatment and hypoxia on HCCO proliferation are variable, suggesting an important role of tumor-cell intrinsic properties in doxorubicin resistance. ABCB1 is a determinant of doxorubicin response in HCCOs. Combination treatment of doxorubicin and ABCB1 inhibition may increase the response rate to transarterial chemoembolization.

Safety, efficacy, and survival of different transarterial chemoembolization techniques in the management of unresectable hepatocellular carcinoma: a comparative single-center analysis.

PURPOSE: Transarterial chemoembolization (TACE) has become the standard of care for the treatment of intermediate-stage hepatocellular carcinoma (HCC). However, current clinical practice guidelines lack consensus on the best selection of a specific TACE technique. This study aims to compare safety, tumor response, and progression-free survival (PFS) of conventional TACE (cTACE), drug-eluting bead TACE (DEB-TACE), and degradable starch microsphere TACE (DSM-TACE). METHODS: This retrospective study included n = 192 patients with HCC who underwent first TACE with unbiased follow-up at 4-6 weeks at our center between 2008 and 2021. Eligibility for TACE was BCLC intermediate stage B, bridging/down-staging (B/D) to liver transplantation (LT), or any other stage when patients were not suitable for resection, LT, local ablation, or systemic therapy. Patients were grouped into three cohorts (n = 45 cTACE, n = 84 DEB-TACE, n = 63 DSM-TACE), and further categorized by TACE indication (B/D or palliative). Liver function and adverse events, response assessed by the modified response evaluation criteria in solid tumors (mRECIST) 4-6 weeks post-TACE and PFS were analyzed. RESULTS: There were no significant differences in age, gender distribution, BCLC stage, or etiology of liver disease among the three TACE groups, even in the B/D or palliative subgroups. DEB-TACE induced slight increases in bilirubin in the palliative subgroup and in lactate dehydrogenase in the entire cohort 4-6 weeks post-TACE, and more adverse events in the palliative subgroup. DEB-TACE and DSM-TACE showed significantly higher disease control rates (complete and partial response, stable disease) compared to cTACE, especially in the B/D setting (p < 0.05). There was no significant difference in PFS between the groups [median PFS (months): cTACE, 10.0 vs. DEB, 7.0 vs. DSM, 10.0; p = 0.436]. CONCLUSION: Our study provides valuable perspectives in the decision-making for a specific TACE technique: DEB-TACE and DSM-TACE showed improved tumor response. DEB-TACE showed a prolonged impact on liver function and more side effects, so patients with impaired liver function should be more strictly selected, especially in the palliative subgroup.

Assessment of safety and efficacy of transarterial chemoembolization combined with camrelizumab and donafenib in patients with hepatocellular carcinoma at BCLC stage C: A study of 20 cases.

Camrelizumab, donafenib, and transarterial chemoembolization (TACE) are recommended for advanced hepatocellular carcinoma (HCC), but their combined efficacy remains unclear. From July 2021 to January 2023, 20 Barcelona Clinic Liver Cancer stage C HCC patients were prospectively enrolled. Inclusion criteria were Eastern Cooperative Oncology Group performance status of 0 or 1, Child-Pugh Score ≤ 7, and Barcelona Clinic Liver Cancer B or C. Surgical candidates were excluded. The treatment included TACE, camrelizumab, and donafenib. Endpoints were median overall survival, progression-free survival, and adverse events (AEs) related to donafenib. Among 20 patients, 85% experienced AEs from targeted therapy and programmed cell death protein-1, with 40% having grade 3 AEs. No grade 4 or 5 AEs occurred. Median follow-up was 9 months, with 15% achieving complete response, 65% partial response, and 15% stable disease. Disease control rate was 90%. Median progression-free survival and overall survival were 9 and 14 months, respectively. TACE, camrelizumab, and donafenib combination therapy in Chinese advanced HCC patients show effectiveness in extending survival with low severe AEs incidence.

Modular multimodal hospital-home chain physical activity rehabilitation programme (3M2H-PARP) in liver cancer: a protocol for a randomised controlled trial.

INTRODUCTION: Patients with liver cancer are susceptible to experiencing a decline in muscle mass and function, which can lead to physical frailty and have a negative impact on prognosis. However, there is currently a lack of physical activity interventions specifically tailored for these patients. Therefore, we have developed a modular multimodal hospital-home chain physical activity rehabilitation programme (3M2H-PARP) designed specifically for patients with liver cancer undergoing transarterial chemoembolisation (TACE). We aim to validate the effectiveness and feasibility of this programme through a randomised controlled trial (RCT). METHODS AND ANALYSIS: 3M2H-PARP RCT will compare a 12-week, modular, multimodal physical activity rehabilitation programme that includes supervised exercise in a hospital setting and self-management exercise at home. The programmes consist of aerobic, resistance, flexibility and balance exercise modules, and standard survivorship care in a cohort of liver cancer survivors who have undergone TACE. The control group will receive standard care. A total of 152 participants will be randomly assigned to either the 3M2H-PARP group or the control group. Assessments will be conducted at three time points: baseline, after completing the intervention and a 24-week follow-up visit. The following variables will be evaluated: liver frailty index, Functional Assessment of Cancer Therapy-Hepatobiliary subscale, Cancer Fatigue Scale, Pittsburgh Sleep Quality Index, Hospital Anxiety and Depression Scale and physical activity level. After the completion of the training programme, semi-structured interviews will be conducted with participants from the 3M2H-PARP group to investigate the programme's impact on their overall well-being. SPSS V.26.0 software will be used for statistical analyses. ETHICS AND DISSEMINATION: Ethical approval has been granted by the Jiangnan University School of Medicine Research Ethics Committee. The findings will be disseminated through publication in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: ChiCTR2300076800.

Multiple asynchronous recurrence as a predictive factor for refractoriness against locoregional and surgical therapy in patients with intermediate-stage hepatocellular carcinoma.

Development of subclassification of intermediate-stage hepatocellular carcinoma (HCC) by treatment suitability is in demand. We aimed to identify predictors that define treatment refractoriness against locoregional(transarterial chemoembolization(TACE) or thermal ablation) and surgical therapy. This multicenter retrospective study enrolled 1167 HCC patients between 2015 and 2021. Of those, 209 patients were initially diagnosed with intermediate-stage HCC. Treatment refractoriness was defined as clinical settings that meets the following untreatable progressive conditions by TACE (1) 25% increase of intrahepatic tumor, (2) transient deterioration to Child-Pugh class C, (3) macrovascular invasion or extrahepatic spread, within one year. We then analyzed factors contributing to treatment refractoriness. The Child-Pugh score/class, number of tumors, infiltrative radiological type, and recurrence were significant factors. Focusing on recurrence as a predictor, median time to untreatable progression (TTUP) was 17.2 months in the recurrence subgroup whereas 35.5 months in the initial occurrence subgroup (HR, 2.06; 95% CI, 1.44-2.96; P = 0.001). Median TTUP decreased in cases with more later times of recurrence (3-5 recurrences, 17.3 months; ≥ 6 recurrences, 7.7 months). Recurrence, even more at later times, leads to increased treatment refractoriness. Early introduction of multidisciplinary treatment should be considered against HCC patients after multiple recurrent episodes.

Prognostic Value of Preoperative MRI-derived 3D Quantitative Tumor Arterial Burden in Patients with Hepatocellular Carcinoma Receiving Transarterial Chemoembolization.

Purpose To investigate the association of tumor arterial burden (TAB) on preoperative MRI with transarterial chemoembolization refractoriness (TACER) and progression-free survival (PFS) in patients with hepatocellular carcinoma (HCC). Materials and Methods This retrospective study included patients with HCC who underwent repeated transarterial chemoembolization (TACE) treatments between January 2013 and December 2020. HCC was confirmed with pathology or imaging, and patients with other tumors, lost follow-up, or with a combination of other treatments were excluded. TACER was defined as viable lesions of more than 50% or increase in tumor number after two or more consecutive TACE treatments, continuous elevation of tumor markers, extrahepatic spread, or vascular invasion. TAB assessed with preoperative MRI was divided into high and low groups according to the median. A Cox proportional hazards model was used to determine the predictors of TACER and PFS. Results A total of 355 patients (median age, 61 years [IQR, 54-67]; 306 [86.2%] men, 49 [13.8%] women) were included. During a median follow-up of 32.7 months, the high TAB group had significantly faster TACER and decreased PFS than the low TAB group (all log-rank P < .001). High TAB was the strongest independent predictor of TACER and PFS in multivariable Cox regression analyses (hazard ratio [HR], 2.23 [95% CI: 1.51, 3.29]; HR, 2.30 [95% CI: 1.61, 3.27], respectively), especially in patients with Barcelona Clinic Liver Cancer stage A or a single tumor. The restricted cubic spline plot demonstrated that the HR of TACER and PFS continuously increased with increasing TAB. Conclusion High preoperative TAB at MRI was a risk factor for faster refractoriness and progression in patients with HCC treated with TACE.

Assessment of disease control rate and safety of sorafenib in targeted therapy for advanced liver cancer.

OBJECTIVE: The clinical efficacy and safety of sorafenib in patients with advanced liver cancer (ALC) were evaluated based on transarterial chemoembolization (TACE). METHODS: 92 patients with ALC admitted to our hospital from May 2020 to August 2022 were randomly rolled into a control (Ctrl) group and an observation (Obs) group, with 46 patients in each. Patients in the Ctrl group received TACE treatment, while those in the Obs group received sorafenib molecular targeted therapy (SMTT) on the basis of the treatment strategy in the Ctrl group (400 mg/dose, twice daily, followed by a 4-week follow-up observation). Clinical efficacy, disease control rate (DCR), survival time (ST), immune indicators (CD3+, CD4+, CD4+/CD8+), and adverse reactions (ARs) (including mild fatigue, liver pain, hand-foot syndrome (HFS), diarrhea, and fever) were compared for patients in different groups after different treatments. RESULTS: the DCR in the Obs group (90%) was greatly higher to that in the Ctrl group (78%), showing an obvious difference (P < 0.05). The median ST in the Obs group was obviously longer and the median disease progression time (DPT) was shorter, exhibiting great differences with those in the Ctrl group (P < 0.05). Moreover, no great difference was observed in laboratory indicators between patients in various groups (P > 0.05). After treatment, the Obs group exhibited better levels in all indicators. Furthermore, the incidence of ARs in the Obs group was lower and exhibited a sharp difference with that in the Ctrl group (P < 0.05). CONCLUSION: SMTT had demonstrated good efficacy in patients with ALC, improving the DCR, enhancing the immune response of the body, and reducing the incidence of ARs, thereby promoting the disease outcome. Therefore, it was a treatment method worthy of promotion and application.

Bronchial arterial chemoembolization with Drug-Eluting beads plus sequential chemotherapy for the treatment of stage III and IV lung squamous cell carcinoma.

PURPOSE: This retrospective study aimed to investigate the effectiveness and safety of bronchial arterial chemoembolization with drug-eluting beads (DEB-BACE) plus chemotherapy versus chemotherapy alone in patients with stage III and IV lung squamous cell carcinoma (LSCC) who are not appropriate candidates for radiochemotherapy. MATERIALS AND METHODS: In this retrospective analysis, we screened all adult patients undergoing either DEB-BACE plus chemotherapy or chemotherapy alone for stage III or IV LCSS at authors' center from January 2018 to August 2021. Each 21-day chemotherapy cycle consisted of intravenous injection of gemcitabine (1.0 g/m2) on days 1 and 8 and cisplatin 75 (mg/m2) on day 1. The planned cycles were 4. DEB-BACE consisted of microcatheter infusion of CalliSpheres beads carrying cisplatin (75 mg/m2) and gemcitabine (1.0 g/m2), at 3 weeks prior to chemotherapy. The primary outcome was overall survival (OS). The secondary outcomes included progression-free survival (PFS), pulmonary response, and adverse events (AEs). RESULTS: The final analysis included 95 patients in the chemotherapy group and 41 patients in the combination treatment group. The median OS was 14 months (95 % CI 11.0-17.0) in the chemotherapy group and 19 months (95 % CI 18.0-24.0) in the combination group (P = 0.015). In multivariate Cox regression analysis, DEB-BACE plus chemotherapy was associated with lower risk of death versus chemotherapy only (HR 0.16, 95 % CI 0.05-0.52; log rank test P = 0.003). The median PFS was 6 months (95 % CI 4.0-7.0) in the chemotherapy group and 8 months (95 % CI 6.0-8.0) in the combination group (P = 0.015). The pulmonary objective response rate (ORR) and disease control rate (DCR) were 48.4 % and 62.1 % in chemotherapy group versus 82.9 % and 90.2 % in combination group (P < 0.001 and = 0.001, respectively). AEs occurred in 133 patients (97.8 %). The rate of bone marrow suppression was 48.4 % (46/95) in the chemotherapy group versus 7.3 % (3/41) in the combination group (P < 0.001). CONCLUSION: Compared with chemotherapy alone, DEB-BACE plus chemotherapy was associated with longer survival outcomes and lower rate of bone marrow suppression.

Biodegradable Microspheres for Transarterial Chemoembolization in Malignant Liver Disease.

Transarterial chemoembolization (TACE) has revolutionized the treatment landscape for malignant liver disease, offering localized therapy with reduced systemic toxicity. This manuscript delves into the use of degradable microspheres (DMS) in TACE, exploring its potential advantages and clinical applications. DMS-TACE emerges as a promising strategy, offering temporary vessel occlusion and optimized drug delivery. The manuscript reviews the existing literature on DMS-TACE, emphasizing its tolerability, toxicity, and efficacy. Notably, DMS-TACE demonstrates versatility in patient selection, being suitable for both intermediate and advanced stages. The unique properties of DMS provide advantages over traditional embolic agents. The manuscript discusses the DMS-TACE procedure, adverse events, and tumor response rates in HCC, ICC, and metastases.

The long-term efficacy of imatinib with hepatic resection or other local treatment for gastrointestinal stromal tumours liver metastases: a retrospective cohort study.

BACKGROUND: The liver is the most common site of metastasis from gastrointestinal stromal tumors (GISTs). The authors aimed to evaluate imatinib (IM) combined with hepatic resection (HR) or other local treatments such as radiofrequency ablation (RFA) and transarterial chemoembolization (TACE), compared to IM monotherapy in long-term survival benefits in patients suffering from GIST liver metastases. METHODS: Our research encompassed 238 patients diagnosed with liver metastases of GISTs from January 2002 to April 2022 at the First Affiliated Hospital of Sun Yat-Sen University. The oncological outcomes of concern included overall survival (OS), progression-free survival (PFS), and liver-specific PFS. RESULTS: Of all 238 patients, 126 were treated with IM alone (IM group), 81 with IM combined with HR (IM+HR group), and 31 with IM combined with RFA/TACE (IM+RFA/TACE group). The median follow-up time was 44.83 months. The median OS in the IM group was 132.60 months and was not reached in either the IM+HR group or the IM+RFA/TACE group. The 10-year OS rate in the IM+HR group was significantly superior to the IM group and the IM+RFA/TACE group (91.9% vs. 61.1% vs. 55.2%, respectively, P =0.015), and the liver-specific PFS ( P =0.642) and PFS ( P =0.369) in the three groups showed a beneficial trend in the combined treatment group. Multivariate analyses showed that age less than or equal to 60 years (HR 0.280, P< 0.001) and IM+HR (HR 0.361, P =0.047) were independently associated with better OS. Achieving no evidence of disease through surgical intervention was independently correlated with enhanced OS (HR 0.099, P =0.034), liver-specific PFS (HR 0.388, P =0.014), and PFS (HR 0.402, P =0.004). CONCLUSIONS: In patients with GIST liver metastases, IM combined with HR might improve OS in selected patients compared with IM alone and IM combined with RFA/TACE. Achieving no evidence of disease status with surgical treatment of patients results in significant prolonging of OS, liver-specific PFS, and PFS.

Evaluation of models to predict prognosis in patients with advanced hepatocellular carcinoma treated with TACE combined with apatinib.

BACKGROUND: The HAP, Six-and-Twelve, Up to Seven, and ALBI scores have been substantiated as reliable prognostic markers in patients presenting with intermediate and advanced hepatocellular carcinoma (HCC) undergoing transarterial chemoembolization (TACE) treatment. Given this premise, our research aims to assess the predictive efficacy of these models in patients with intermediate and advanced HCC receiving a combination of TACE and Apatinib. Additionally, we have conducted a meticulous comparative analysis of these four scoring systems to discern their respective predictive capacities and efficacies in combined therapy. METHODS: Performing a retrospective analysis on the clinical data from 200 patients with intermediate and advanced HCC, we studied those who received TACE combined with Apatinib at the First Affiliated Hospital of the University of Science and Technology of China between June 2018 and December 2022. To identify the factors affecting survival, the study performed univariate and multivariate Cox regression analyses, with calculations of four different scores: HAP, Six-and-Twelve, Up to Seven, and ALBI. Lastly, Harrell's C-index was employed to compare the prognostic abilities of these scores. RESULTS: Cox proportional hazards model results revealed that the ALBI score, presence of portal vein tumor thrombus (PVTT, )and tumor size are independent determinants of prognostic survival. The Kaplan-Meier analyses showed significant differences in survival rates among patients classified by the HAP, Six-and-Twelve, Up to Seven, and ALBI scoring methods. Of the evaluated systems, the HAP scoring demonstrated greater prognostic precision, with a Harrell's C-index of 0.742, surpassing the alternative models (P < 0.05). In addition, an analysis of the area under the AU-ROC curve confirms the remarkable superiority of the HAP score in predicting short-term survival outcomes. CONCLUSION: Our study confirms the predictive value of HAP, Six-and-Twelve, Up to Seven, and ALBI scores in intermediate to advanced Hepatocellular Carcinoma (HCC) patients receiving combined Transarterial Chemoembolization (TACE) and Apatinib therapy. Notably, the HAP model excels in predicting outcomes for this specific HCC subgroup.

A Rare Early-Onset Fatal Complication after Transarterial Chemoembolization: A Case Report and Review of the Literature.

Transarterial chemoembolization (TACE) is a minimally invasive treatment for liver cancer, often employed as a bridging therapy or destination treatment for non-operable cases. This case report discusses an 82-year-old woman with a large hepatocellular carcinoma (HCC) who underwent elective TACE due to the high surgical risk associated with her tumor size. Unexpectedly, the patient experienced liver rupture 20 h post-procedure, leading to acute surgical intervention. Despite successful hemostasis during surgery, the patient succumbed to progressive multi-organ failure. We aimed to search the PubMed database for documented cases of ruptured HCC after TACE. This study highlights risk factors for spontaneous HCC rupture and specific factors associated with TACE-induced rupture. Transarterial embolization (TAE) is currently favored as the treatment method for spontaneous ruptures, while the optimal therapy for TACE-induced ruptures remains unclear. In conclusion, this case underscores the importance of recognizing the rare complication of HCC rupture post-TACE and the need for personalized risk assessment. While TAE emerges as a primary treatment choice, the lack of consensus necessitates further studies to establish evidence-based approaches for managing this uncommon yet life-threatening complication.

Controlling Nutritional Status (CONUT) Score is Associated with Overall Survival in Patients with Hepatocellular Carcinoma Treated with Conventional Transcatheter Arterial Chemoembolization: A Propensity Score Matched Analysis.

PURPOSE: This study aims to evaluate the prognostic value of controlling nutritional status (CONUT) score in determining the prognosis of patients with hepatocellular carcinoma (HCC) treated with conventional transcatheter arterial chemoembolization (cTACE). METHODS: This study retrospectively analyzed 936 patients who underwent cTACE for HCC between January 2012 and December 2018, and divided them into two groups based on their CONUT score. To balance the bias in baseline characteristics, propensity score matched (PSM) analysis was conducted. The Kaplan-Meier method was used to establish a cumulative survival curve, and the log-rank test was employed to determine differences in overall survival (OS) and progression-free survival (PFS) among the CONUT score groups. Furthermore, the Cox proportional hazard model was employed to assess the correlation between CONUT score and OS and PFS, whereby hazard ratios (HRs) and 95% confidence intervals (95% CIs) were computed. RESULTS: Before PSM, the median OS for the low (≤ 3) and high (≥ 4) CONUT group (558 vs. 378 patients) was 21.7 and 15.6 months, respectively, and the median PFS was 5.7 and 5 months. Following PSM, both the low and high CONUT score groups comprised 142 patients. The low CONUT score group exhibited a significantly longer OS compared to the high CONUT score group, as determined by the log-rank test (median OS 22.2 vs. 17.0 months, P = 0.014). No significant association was observed between CONUT group and PFS (median PFS 6.4 vs. 4.7 months, log-rank test, P = 0.121). Cox proportional hazard regression analysis revealed that a CONUT score of ≥ 4 was an independent risk factor for OS in patients with HCC who underwent cTACE (HR = 1.361; 95% CI: 1.047-1.771; P = 0.022). These findings were consistent across most subgroup analyses. CONCLUSION: A high CONUT score has been found to be a prognostic factor for poorer OS in patients with HCC who underwent cTACE. LEVEL OF EVIDENCE: Level 3, Non-randomized controlled cohort.

Combination of Doxorubicin and Antiangiogenic Agents in Drug-Eluting Beads: In Vitro Loading and Release Dynamics in View of a Novel Therapeutic Approach for Hepatocellular Carcinoma.

PURPOSE: Antiangiogenic agents have been used for many years as a first-line systemic treatment for advanced HCC. Embolization with cytostatic drugs on the other hand is the first-line treatment for intermediate HCC. The two types of drugs have not been combined for intraarterial delivery yet. The loading and release dynamics and the in vitro effect of their combination are tested in this experimental study. MATERIALS AND METHODS: Drug-eluting beads were loaded with doxorubicin, sunitinib and sunitinib analogue piperazine (SAP) alone and with their combinations. Diameter change, loading, release, and effect in cellular proliferation were assessed. RESULTS: The average microsphere diameter after loading was 473.7 µm (µm) for Doxorubicin, 388.4 µm for Sunitinib, 515.5 µm for SAP, 414.8 µm for the combination Doxorubicin/Sunitinib and 468.8 µm for the combination Doxorubicin /SAP. Drug release in 0.9% NaCl was 10% for Doxorubicin, 49% for Sunitinib, 25% for SAP, 20%/18% for the combination Doxorubicin/Sunitinib, and 18%/23% for the combination Doxorubicin/SAP whereas in human plasma it was 56%, 27%, 13%, 76%/63% and 62%/15%, respectively. The mean concentration of Doxorubicin that led to inhibition of 50% of cellular proliferation in an HCC Huh7 cell line was 163.1 nM (nM), for Sunitinib 10.3 micromolar (µΜ), for SAP 16.7 µΜ, for Doxorubicin/Sunitinib 222.4 nM and for Doxorubicin/SAP 275 nM. CONCLUSIONS: Doxorubicin may be combined with antiangiogenic drugs with satisfactory in vitro loading and release outcomes and effect on cellular lines.
