Present and future of new systemic therapies for early and intermediate stages of hepatocellular carcinoma

Hepatocellular carcinoma (HCC) is a high mortality neoplasm which usually appears on a cirrhotic liver. The therapeutic arsenal and subsequent prognostic outlook are intrinsically linked to the HCC stage at diagnosis. Notwithstanding the current deployment of treatments with curative intent (liver resection/local ablation and liver transplantation) in early and intermediate stages, a high rate of HCC recurrence persists, underscoring a pivotal clinical challenge. Emergent systemic therapies (ST), particularly immunotherapy, have demonstrate promising outcomes in terms of increase overall survival, but they are currently bound to the advanced stage of HCC. This review provides a comprehensive analysis of the literature, encompassing studies up to March 10th, 2024, evaluating the impact of novel ST in the early and intermediate HCC stages, specially focusing on the findings of neoadjuvant and adjuvant regimens, aimed at increasing significantly overall survival and recurrence-free survival after a treatment with curative intent. We also investigate the potential role of ST in enhancing the downstaging rate for the intermediate-stage HCC initially deemed ineligible for treatment with curative intent. Finally, we critically discuss about the current relevance of the results of these studies and the encouraging future implications of ST in the treatment schedules of early and intermediate HCC stages.

Sorafenib plus TACE with or without camrelizumab for the treatment of intermediate and advanced hepatocellular carcinoma.

To compare the efficacy and safety of transcatheter arterial chemoembolization (TACE) combined with sorafenib and camrelizumab or with sorafenib alone in patients with intermediate or advanced hepatocellular carcinoma (HCC). We retrospectively analyzed 78 patients with intermediate or advanced HCC who were treated at our centers between January 2018 and December 2021. 26 of them received sorafenib and camrelizumab plus TACE (the TACE + Sor + C group), while 52 received TACE and sorafenib (the TACE + Sor group). Overall survival (OS), progression-free survival (PFS), and adverse events (AEs) were evaluated. Univariate and multivariate analyses were used to determine the factors affecting survival. The mOS (22 vs. 10 months, P < 0.001) and mPFS (11 vs. 6 months, P = 0.008) of the TACE + Sor + C group were significantly higher than those of the TACE + Sor group. Multivariate analysis showed that compared with TACE + Sor + C, TACE + Sor increased the risk of all-cause mortality and tumor progression. For grade I and II adverse events (AEs), the incidence of skin capillary hyperplasia and hypothyroidism in the TACE + Sor + C group was significantly higher than that in the TACE + Sor group. For serious AEs (grade III or IV), there was no significant difference in any adverse reaction between the two groups (P > 0.05). Patients with intermediate or advanced HCC appeared to benefit more in terms of survival from TACE + Sor + C than from TACE + Sor, and the AEs were tolerable. 1.Subgroup analysis demonstrated TACE+ Sorafenib+ Camrelizumab could benefit HCC patients regardless of whether they had PVTT, BCLC B or C, or CHILD A or B；2.We reported the immunotherapy related adverse events (irAEs) occurred with a significant higher incidence in triple treatment, but all the adverse events are tolerable.

Conversion therapy for advanced hepatocellular carcinoma in the era of precision medicine: Current status, challenges and opportunities.

Hepatocellular carcinoma (HCC), the most prevalent malignancy of the digestive tract, is characterized by a high mortality rate and poor prognosis, primarily due to its initial diagnosis at an advanced stage that precludes any surgical intervention. Recent advancements in systemic therapies have significantly improved oncological outcomes for intermediate and advanced-stage HCC, and the combination of locoregional and systemic therapies further facilitates tumor downstaging and increases the likelihood of surgical resectability for initially unresectable cases following conversion therapies. This shift toward high conversion rates with novel, multimodal treatment approaches has become a principal pathway for prolonged survival in patients with advanced HCC. However, the field of conversion therapy for HCC is marked by controversies, including the selection of potential surgical candidates, formulation of conversion therapy regimens, determination of optimal surgical timing, and application of adjuvant therapy post-surgery. Addressing these challenges and refining clinical protocols and research in HCC conversion therapy is essential for setting the groundwork for future advancements in treatment strategies and clinical research. This narrative review comprehensively summarizes the current strategies and clinical experiences in conversion therapy for advanced-stage HCC, emphasizing the unresolved issues and the path forward in the context of precision medicine. This work not only provides a comprehensive overview of the evolving landscape of treatment modalities for conversion therapy but also paves the way for future studies and innovations in this field.

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

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. 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. 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. 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.

The efficacy and safety of PD-1 inhibitor combined with TACE in the first-line treatment of unresectable hepatocellular carcinoma.

The application of immune checkpoint inhibitors (ICIs) has changed the treatment of advanced hepatocellular carcinoma. Transcatheter arterial chemoembolization (TACE) is a first-line treatment for intermediate hepatocellular carcinoma. Serving as a local treatment modality that can induce immunogenic cell death, the efficacy and safety of combined use with ICI have not been evaluated. Although there have been prospective studies aimed at evaluating the efficacy and safety of ICI combined with TACE in BCLC stage B HCC patients, there are few reports on the evaluation of BCLC stage C patients with distant metastasis or portal vein cancer thrombus. Data of unresectable hepatocellular carcinoma patients received PD-1 inhibitor and TACE were collected in Xijing Hospital from June 2019 to December 2022. The tumor response was evaluated according to the Solid Tumor Modified Response Evaluation Standard (mRECIST), including complete response (CR), partial response (PR), disease stability (SD), disease progression (PD), objective response rate (ORR), and disease control rate (DCR). The progression-free survival (PFS) and overall survival (OS) were used to estimate therapy efficacy. The treatment-related adverse events were evaluated based on National Cancer Institute Common Adverse Event Evaluation Criteria (CTCAE) version 5.0. A total of 42 patients with unresectable hepatocellular carcinoma were included in this study, including 34 males (80.5%) and 8 females (19.5%). The average age is 54.5years, ranging from 34 to 72. The median follow-up time was 12.3months, with an ORR of 42.9% and a DCR of 90.5% as of the follow-up time. The median PFS is 7.5months (95% CI: 5.76-9.23), and the median OS has not yet been reached; 6-month PFS was 62.2%. Safety analysis showed that 41 (97.6%) patients experienced treatment-related adverse reactions, mainly including elevated AST and ALT, fever, elevated bilirubin, hypothyroidism, nausea, abdominal pain, and rash. 40 patients had grade 1/2 adverse reactions, and only one patient had grade 3 adverse reactions, manifested as intolerable rash, nausea, and vomiting. Treatment is terminated when symptomatic treatment and drug suspension cannot be alleviated. In this study, thre patients with unresectable hepatocellular carcinoma were treated with PD-1 inhibitor combined with TACE to achieve good tumor reduction effect and underwent liver cancer resection surgery. For patients with unresectable hepatocellular carcinoma, whether in BCLC stage B or stage C, effective systemic therapy (PD-1 inhibitor) combined with local therapy (TACE) can achieve a high rate of tumor regression and objective response. Some patients may even pursue surgical treatment opportunities, and the treatment-related adverse reactions are controllable, which is expected to provide new options for extending the survival of unresectable hepatocellular carcinoma patients.

Non-invasive assessment of response to transcatheter arterial chemoembolization for hepatocellular carcinoma with the deep neural networks-based radiomics nomogram.

Transcatheter arterial chemoembolization (TACE) is a mainstay treatment for intermediate and advanced hepatocellular carcinoma (HCC), with the potential to enhance patient survival. Preoperative prediction of postoperative response to TACE in patients with HCC is crucial. To develop a deep neural network (DNN)-based nomogram for the non-invasive and precise prediction of TACE response in patients with HCC. We retrospectively collected clinical and imaging data from 110 patients with HCC who underwent TACE surgery. Radiomics features were extracted from specific imaging methods. We employed conventional machine-learning algorithms and a DNN-based model to construct predictive probabilities (RScore). Logistic regression helped identify independent clinical risk factors, which were integrated with RScore to create a nomogram. We evaluated diagnostic performance using various metrics. Among the radiomics models, the DNN_LASSO-based one demonstrated the highest predictive accuracy (area under the curve [AUC] = 0.847, sensitivity = 0.892, specificity = 0.791). Peritumoral enhancement and alkaline phosphatase were identified as independent risk factors. Combining RScore with these clinical factors, a DNN-based nomogram exhibited superior predictive performance (AUC = 0.871, sensitivity = 0.844, specificity = 0.873). In this study, we successfully developed a deep learning-based nomogram that can noninvasively and accurately predict TACE response in patients with HCC, offering significant potential for improving the clinical management of HCC.

Intermediate-stage hepatocellular carcinoma: refining substaging or shifting paradigm?

This review explores the evolution of cancer staging, focusing on intermediate hepatocellular carcinoma (HCC), and the challenges faced by physicians. The Barcelona Clinic Liver Cancer (BCLC) staging system, introduced in 1999, was designed to address the limitations associated with providing accurate prognostic information for HCC and allocating specific treatments, to avoid overtreatment. However, criticism has emerged, particularly regarding the intermediate stage of HCC (BCLC-B) and its heterogeneous patient population. To overcome this limitation, various subclassification systems, such as the Bolondi and Kinki criteria, have been proposed. These systems are aimed at refining categorizations within the intermediate stage and have demonstrated varying degrees of success in predicting outcomes through external validation. This study discusses the shift in treatment paradigms, emphasizing the need for a more personalized approach rather than strictly adhering to cancer stages, without dismissing the relevance of staging systems. It assesses the available treatment options for intermediate-stage HCC, highlighting the importance of considering surgical and nonsurgical options alongside transarterial chemoembolization for optimal outcomes. In conclusion, the text advocates for a paradigm shift in staging systems prioritizing treatment suitability over cancer stage. This reflects the evolving landscape of HCC management, where a multidisciplinary approach is crucial for tailoring treatments to individual patients, ultimately aiming to improve overall survival.

Procoagulant CaCO3-embedded embolic microspheres can potentiate transcatheter arterial embolization of hepatocellular carcinoma

Transcatheter arterial embolization (TAE) represents a preferred therapeutic modality with minimal invasiveness for unresectable intermediate and advanced hepatocellular carcinoma (HCC) patients. However, its therapeutic outcome is restricted by incomplete occlusion of the whole tumor vasculature and exacerbated tumor immunosuppression due to the lack of ideal embolic agents. Herein, procoagulant embolic microspheres with tunable sizes are prepared by loading thrombin into calcium carbonate (CaCO3) nanoparticle-embedded gelatin microspheres (Th-CaCO3@gelatin MSs) via a microfluidic process. In this system, the yielded Th-CaCO3@gelatin MSs are capable of occluding main tumor-feeding blood vessels, while the released thrombin and Ca2+ triggered by the acidic tumor microenvironment can synergistically promote the formation of intravascular blood clots to occlude tumor capillaries. Meanwhile, the embedded CaCO3 nanoparticles can work as proton sponges to neutralize tumor acidity and thus effectively reverse tumor immunosuppression. Resultantly, TAE treatment with Th-CaCO3@gelatin MSs exhibits the most effective tumor suppression efficacy on orthotopic N1S1 HCC rat xenografts without causing obvious toxic effects. Therefore, this study highlights that our biocompatible embolic microspheres are capable of potentiating conventional TAE treatment by promoting pH-responsive tumor vascular infarction and neutralizing the acidic tumor microenvironment, with great potential in clinical translation.

Defining a radiomics feature selection method for predicting response to transarterial chemoembolization in hepatocellular carcinoma patients

AimTo assess the utility of different radiomics feature selection methods in predicting transarterial chemoembolization (TACE) response in hepatocellular carcinoma (HCC) patients. Materials and methodsThis study employed a dataset of 136 paired MR T1-weighted contrast-enhanced abdominal images with liver tumor masks before and after TACE. TACE response for each image pair was classified by European Association for the Study of the Liver (EASL) and modified Response Evaluation Criteria in Solid Tumors (mRECIST) guidelines. 100D feature vectors were generated for the paired tumor areas. Eighteen existing feature selection methods were employed to select the top-k features to train and test a non-linear support vector machine (SVM) with a Gaussian kernel. Five-cross validation was performed to identify the highest performing feature selection methods. ResultsFor all benchmarks, a L0-based method selecting the top-5 or top-10 features achieved the highest performance. For images classified with EASL criteria that were analyzed with the L0-based method, the accuracy (ACC), area under curve (AUC), and balanced F score (F1-score) were 0.75 ​± ​0.06, 0.75 ​± ​0.09, and 0.80 ​± ​0.05, respectively. For images classified with mRECIST criteria that were analyzed with the L0-based method, the ACC, AUC, and F1-score were 0.75 ​± ​0.07, 0.71 ​± ​0.16, and 0.82 ​± ​0.04, respectively. ConclusionA L0-based method that selected the top-5/10 most important features predicted TACE response in HCC patients with the highest accuracy under both EASL and mRECIST criteria. This proof-of-concept investigation represents a step forward in the development of a reliable clinical decision-making tool for management of intermediate HCC patients undergoing TACE.

Hepatocellular Carcinoma in Ceará: Epidemiology and Treatment in a Reference Liver Transplant Center in Northeast Brazil

Hepatocellular carcinoma remains a significant worldwide malignancy and an important cause of cancer-related death. The incidence is increasing globally. In Latin America, there is no consistent data on the epidemiology of hepatocellular carcinoma. However, Brazil is considered a country with an intermediate incidence of this liver neoplasm. In the state of Ceará, situated in the northeast region of Brazil, there are no consistent clinical and epidemiologic data on the actual incidence and the treatment of hepatocellular carcinoma. The purpose of this article is to describe epidemiologic characteristics and treatment forms of patients with hepatocellular carcinoma who were treated in a Liver Transplant Center. A retrospective observational study was conducted using the database from the register of 299 patients with hepatocellular carcinoma between June 2004 and February 2022. Only patients born in Ceará were included. Therefore, most patients were eligible, based on the Milan Criteria, to undergo liver transplantation with a Model End Stage Liver Disease score of 12.48 ± 4.66 points, and the waiting list time was approximately 7 months with 8.7% hepatocellular carcinoma recurrence after liver transplant. A total of 38.5 % of cases were outside the Milan criteria at the time of cancer diagnosis, and transarterial chemoembolization was the main treatment choice. In conclusion, the diagnosis of hepatocellular carcinoma in Ceará mainly occurs in male patients with hepatitis C or alcoholism, with a mean age of 61.55 years and a previous diagnosis of liver disease. Liver transplantation was the best curative therapeutic form in patients with cirrhosis and hepatocellular carcinoma in Ceará, where a significant number of patients were diagnosed with intermediate and advanced-stage hepatocellular carcinoma, so public health policies are important for the screening and monitoring of liver disease.

Hepatic arterial infusion chemotherapy combined with lenvatinib and PD-1 inhibitors versus lenvatinib and PD-1 inhibitors for HCC refractory to TACE.

The study aims to investigate the efficacy and safety of hepatic arterial infusion chemotherapy (HAIC) combined with lenvatinib and immune checkpoint inhibitors (ICIs) versus lenvatinib and ICIs for hepatocellular carcinoma (HCC) with transarterial chemoembolization (TACE) refractoriness. Patients with intermediate or advanced TACE-refractory HCC who received lenvatinib and ICIs with or without HAIC between 2020 and 2022 were retrospectively reviewed. The tumor response, overall survival (OS), progression-free survival (PFS), and treatment-related adverse events (TRAEs) were evaluated and compared between the two groups. Factors affecting OS and PFS were identified with univariate and multivariate Cox regression analyses. A total of 121 patients were enrolled, with 58 patients assigned to the HAIC-Len-ICI group and 63 patients assigned to the Len-ICI group. A higher objective response rate and disease control rate were found in the HAIC-Len-ICI group than in the Len-ICI group (48.30% vs 23.80%, P=0.005; 87.90% vs 69.80%, P=0.02, respectively). The median OS was 24.0months in the HAIC-Len-ICI group and 13.0months in the Len-ICI group (P=0.001). The median PFS was 13.0months in the HAIC-Len-ICI group and 7.2months in the Len-ICI group (P<0.001). Multivariable analyses suggested that the presence of cirrhosis, Child-Pugh B stage, and HAIC-Len-ICI therapy option were prognostic factors for OS and PFS. The incidences of any grade and grade 3/4 TRAEs were both comparable between the two groups. HAIC combined with lenvatinib and ICIs yielded better OS, PFS, ORR, and DCR than lenvatinib-ICI therapy in patients with HCC refractory to TACE, with manageable adverse events.

Feasibility Study of Computed Tomographic Radiomics Model for the Prediction of Early and Intermediate Stage Hepatocellular Carcinoma Using BCLC Staging.

Hepatocellular carcinoma (HCC) is a serious health concern because of its high morbidity and mortality. The prognosis of HCC largely depends on the disease stage at diagnosis. Computed tomography (CT) image textural analysis is an image analysis technique that has emerged in recent years. To probe the feasibility of a CT radiomic model for predicting early (stages 0, A) and intermediate (stage B) HCC using Barcelona Clinic Liver Cancer (BCLC) staging. A total of 190 patients with stages 0, A, or B HCC according to CT-enhanced arterial and portal vein phase images were retrospectively assessed. The lesions were delineated manually to construct a region of interest (ROI) consisting of the entire tumor mass. Consequently, the textural profiles of the ROIs were extracted by specific software. Least absolute shrinkage and selection operator dimensionality reduction was used to screen the textural profiles and obtain the area under the receiver operating characteristic curve values. Within the test cohort, the area under the curve (AUC) values associated with arterial-phase images and BCLC stages 0, A, and B disease were 0.99, 0.98, and 0.99, respectively. The overall accuracy rate was 92.7%. The AUC values associated with portal vein phase images and BCLC stages 0, A, and B disease were 0.98, 0.95, and 0.99, respectively, with an overall accuracy of 90.9%. The CT radiomic model can be used to predict the BCLC stage of early-stage and intermediate-stage HCC.

Lymphocyte subsets and inflammatory factors as predictors of immunotherapy efficacy in patients with hepatocellular carcinoma

We aimed to investigate the correlation between lymphocyte subpopulations expressing inhibitor receptors, IL-6 levels, and the efficacy of immunotherapy in patients with hepatocellular carcinoma. Blood samples were prospectively collected before and after immunotherapy from patients with intermediate and advanced hepatocellular carcinoma who were treated with immunotherapy at the Fifth Medical Center of the PLA General Hospital from August 2022 to October 2023. According to the efficacy of the patients, patients were divided into effective and ineffective groups, with 40 in the effective group and 44 in the ineffective group. We compared changes in lymphocyte subsets and IL-6 levels between the two groups. Optimal cut-off value was determined using ROC curves. Then, patients were categorized into high and low groups based on cut-off value, and the disease control rates and progression free survival were compared. Before immunotherapy, there were no significant differences in the baseline levels of lymphocyte subsets (PD1 + TIM3 + T/T, TIGIT + T/T, TIM3 + T/T, CTLA4 + T/T, LAG3 + T/T, PD1 + T/T) and IL-6 between the two groups (P > 0.05). After immunotherapy, the levels of PD1 + TIM3 + T/T, TIGIT + T/T, and IL-6 in the effective group were lower than those in the ineffective group and these differences were statistically significant (P = 0.001, P = 0.008, P = 0.000). However, the levels of other lymphocyte subsets showed no significant difference. Using the ROC curve to assess efficacy prediction, PD1 + TIM3 + T/T, TIGIT + T/T and IL-6 demonstrated high predictive ability (AUC = 0.79, AUC = 0.81, AUC = 0.78). The predictive value of efficacy was further improved when all three factors were combined (AUC = 0.92, P = 0.000). Based on the ROC curve, we identified optimal cut-off value for three factors. Notably, patients with values below the optimal cut-off value had higher disease control rate and progression free survival. The levels of PD1 + TIM3 + T/T, TIGIT + T/T, and IL-6 after 2 cycles of immunotherapy may serve as predictors of treatment efficacy in patients with hepatocellular carcinoma.

Tyrosine kinase inhibitors, immune checkpoint inhibitors combined with hepatic arterial infusion of oxaliplatin and raltitrexed versus oxaliplatin, 5-fluorouracil and leucovorin for intermediate and advanced hepatocellular carcinoma: A retrospective study

BackgroundHepatic arterial infusion chemotherapy (HAIC) has demonstrated promising benefits in treating advanced hepatocellular carcinoma (HCC). In China, the most frequently used HAIC regimen is oxaliplatin, 5-fluorouracil, and leucovorin (FOLFOX). However, arterial infusion of fluorouracil over 46 h was not convenient. Raltitrexed, another antimetabolic agent with a long plasma half-life, allows for shorter infusion durations. We aimed to compare the effectiveness and toxicity of tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibitors (ICIs) combined with HAIC with raltitrexed plus oxaliplatin (RALOX) or FOLFOX in patients with intermediate and advanced HCC. MethodsThis retrospective study enrolled 82 eligible patients from February 2019 to December 2021. Forty patients were treated with FOLFOX HAIC (oxaliplatin 85 mg/m2, leucovorin 400 mg/m2, 5-fluorouracil bolus 400 mg/m2 administered on day 1, and 5-fluorouracil 2400 mg/m2 infusion for 46 h, every 3 weeks) combined with TKIs and ICIs. Forty-two patients received RALOX HAIC (oxaliplatin 100 mg/m2 and raltitrexed 3 mg/m2 on day 1, every 3 weeks) combined with TKIs and ICIs. We compared the objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and safety profile. ResultsORR was similar between the FOLFOX HAIC and RALOX HAIC groups (42.5% vs 42.5%, P = 0.974). DCR also showed no significant difference between the two groups (87.5% vs 85.7%, P = 0.813). Median PFS was 10.7 months in the FOLFOX HAIC group versus 10.2 months in the RALOX HAIC group (P = 0.41). Median OS was 20.3 months in the FOLFOX HAIC group, compared to 17.7 months in the RALOX HAIC group (P = 0.50). Both groups had similar profiles of grade 3/4 treatment-related adverse events, including thrombocytopenia, increased aspartate aminotransferase, increased alanine aminotransferase, and leukocytopenia. ConclusionThe effectiveness and safety of HAIC with RALOX were comparable to HAIC with FOLFOX in intermediate and advanced HCC patients.

Transarterial Chemoembolization for Patients with Unresectable Hepatocellular Carcinoma with Child-Pugh B7.

This study aimed to evaluate the efficacy and safety of transarterial chemoembolization (TACE) in patients with unresectable early or intermediate hepatocellular carcinoma (HCC) and Child-Pugh (CP)-B liver dysfunction. This multicenter retrospective study enrolled patients with treatment-naïve HCC treated with TACE monotherapy between January 2012 and December 2020 at six Chinese hospitals. The primary outcome was overall survival (OS), and the secondary outcomes included the objective response rate (ORR) according to the modified RECIST and adverse events (AEs). Propensity score matching (PSM) was performed to reduce bias between the CP-B and CP-A groups. A total of 847 patients were included in the study. CP-A patients had significantly longer OS (median, 22.0 vs 19.3 months, P = 0.032) than CP-B (score of 7-9) patients, but a non-significant trend compared with CP-B (score of 7) patients (median, 22.0 vs 20.5 months, P = 0.254). After PSM, the median OS was 22.7 months for CP-A patients, while it was 19.3 months for CP-B (score of 7-9) patients (p = 0.026) and 20.5 months for CP-B (score of 7) patients (p = 0.155). CP-A patients achieved a significantly better ORR (53.0% vs 35.8%, P < 0.05) compared to CP-B (score of 7-9) patients, but a non-significant trend was observed in CP-B (score of 7) patients (53.0% vs 51.1%, P > 0.05). The post-embolization syndrome rates in the CP-A and CP-B (score of 7) cohorts were 52.1% and 53.3%, respectively. No new safety concerns were observed. Patients with HCC with a CP score of 7 receiving TACE showed a similar prognosis and safety profile to CP-A patients.

Analysis of the safety and effectiveness of TACE combined with targeted immunotherapy in the treatment of intermediate and advanced hepatocellular carcinoma.

To evaluate the effectiveness and safety of transarterial chemoembolization (TACE) combined with immune and targeted therapy in unresectable hepatocellular carcinoma (HCC). Prospective analysis of 23 patients with intermediate or advanced primary HCC treated at the Department of Hepatic Surgery, The First Affiliated Hospital of the University of Science and Technology of China from July 2019, including 11 cases treated with TACE alone and 12 cases treated with TACE combined with targeted therapy. The basal indexes of patients in the two groups were compared, and the response during treatment was observed; regular follow-up was performed to assess the efficacy of tumor treatment. Compared with TACE treatment alone, the objective response rate (ORR) was significantly higher in the TACE combined with targeted treatment group (50.0% vs 36.4%), with a higher success rate of surgical conversion (33.3% vs 18.2%) and a significantly longer progression-free survival (PFS) (20.5 ± 2.9months vs 11.6 ± 2.9months). Multifactorial regression analysis identified tumor vascular invasion as an independent prognostic factor affecting HCC. No patient experienced catheter retention-related complications during treatment, and there were no intolerable adverse effects. TACE combined with targeted treatment for intermediate to advanced unresectable HCC was effective, with good tumor responsiveness, high surgical conversion rate, and safe and controllable adverse reactions during treatment.
