Objective:To explore the value of radiomics and deep learning in predicting the efficacy of initial transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC).Methods:This was a cohort study. The imaging and clinical information of HCC patients treated with TACE in the Second Affiliated Hospital of Harbin Medical University from January 2015 to January 2021 were collected retrospectively. A total of 265 patients were divided into response group (175 cases) and non-response group (90 cases) according to the modified solid tumor efficacy evaluation criteria (mRECIST) 1 to 2 months after initial TACE. According to the proportion of 8∶2, the patients were randomly divided into training group (212 cases, 140 responders and 72 non-responders) and test set (53 cases, 35 responders and 18 non-responders). Univariate and multivariate logistic regression was used to screen clinical variables and construct a clinical model. The radiomics features were extracted from the preoperative CT images, and radiomics model was constructed after feature dimensionality reduction. Using the deep learning method, three residual network (ResNet) models (ResNet18, ResNet50 and ResNet101) were established, and their effectiveness was compared and integrated to build a deep learning model with best performance. Univariate and multivariate logistic regression was used to combine pairwise three models to establish the combined model. The receiver operating characteristic curve was used to evaluate the performance of the model to distinguish between TACE response and non-response groups.Results:In the test set, the area under the curve (AUC) of the clinical model and the radiomics model in the differentiation between response and non-response after TACE were 0.730 (95% CI 0.569-0.891) and 0.775 (95% CI 0.642-0.907). The AUC of ResNet18, ResNet50 and ResNet101 were 0.719, 0.748 and 0.533, respectively. The AUC for deep learning model obtained by integrating ResNet18 and ResNet50 was 0.806 (95% CI 0.665-0.946). After pairwise fusion, the combined deep learning-radiomics model showed the highest performance, with an AUC of 0.843 (95% CI 0.730-0.956), which was better than those of the deep learning-clinical model (AUC of 0.838, 95% CI 0.719-0.957) and the radiomics-clinical model (AUC of 0.786, 95% CI 0.648-0.898). Conclusions:The combined model of radiomics and deep learning has high performance in predicting the curative effect of TACE in patients with HCC before operation.

Objective:To analyze the prognosis of hepatocellular carcinoma (HCC) patients with thrombocytosis (platelet count ≥350×10 9) after transcatheter arterial chemoembolization (TACE), and the effect of thrombocytosis on the prognosis of patients with HCC after TACE. Methods:Clinical data of 867 patients with HCC admitted to the Department of Interventional Radiology, the Affiliated Hospital of Xuzhou Medical University from January 2013 to May 2018 were retrospectively analyzed. After propensity score matching, 99 patients were enrolled, including 70 males and 29 females, aged (60.1±12.1) years. Patients were divided into the groups with thrombocytosis ( n=33) and without thrombocytosis ( n=66). The gender, maximum tumor diameter, Barcelona clinical liver cancer (BCLC) stage, and total bilirubin were compared between the two groups. The association of thrombocytosis with the prognosis of HCC after TACE treatment were analyzed using univariate and multivariate Cox regression. Results:After propensity score matching, the male proportion, maximum tumor diameter, BCLC stage, and serum level of total bilirubin were comparable between the groups (all P>0.05). Before TACE treatment, the platelet count of patients with thrombocytosis was (394.4±54.5)×10 9/L, which was higher than that after TACE [(278.2±86.4)×10 9/L, t=7.63, P<0.001]. The progression-free survival rates after TACE in without thrombocytosis group were 83.3%, 24.2%, and 7.6% at 3, 6 and 9 months, respectively, better than those in thrombocytosis group (51.5%, 3.0%, and 3.0%, respectively; χ2=31.24, P<0.001). The overall survival rates after TACE in without thrombocytosis group were 81.8%, 30.3%, and 4.5% at 1, 2 and 3 years, respectively, better than those in thrombocytosis group (15.2%, 9.1%, and 3.0%, respectively; χ2=27.89, P<0.001). Multivariate Cox regression analysis showed that patients of HCC with thrombocytosis had an increased risk of tumor progression ( HR=5.785, 95% CI: 3.291-10.168, P<0.001) and increased risk of death ( HR=4.090, 95% CI: 2.482-6.740, P<0.001) after TACE. Conclusion:The prognosis of TACE for HCC might be worse in patients with thrombocytosis. Thrombocytosis is a risk factor for cumulative survival and progression-free survival of HCC patients after TACE.

Objective:To evaluate the relationship between red blood cell distribution width (RDW) and prognosis of patients with hepatocellular carcinoma (HCC) andergoing transcatheter arterial chemoembolization (TACE).Methods:Clinical data of 212 patients with HCC andergoing TACE for the first time in Department of Interventional Radiology, the Affiliated Hospital of Xuzhou Medical University from January 2011 to May 2018 were retrospectively analyzed, including 184 males and 28 females, aged (56.8±11.2) years. Follow-up for survival. X-tile software was used to determine 13.1% as the optimal threshold for preoperative RDW prediction of prognosis, and enrolled patients were divided into a low level group (RDW<13.1%, n=70) and a high level group (RDW≥13.1%, n=142). Aspartate aminotransferase, total bilirubin, albumin, hemoglobin and lipoprotein a, Barcelona clinical liver cancer (BCLC) stage and other indexes were compared between the two groups. Survival analysis was performed by Kaplan-Meier method, survival rate was compared by log-rank test, and the effect of RDW on prognosis was analyzed by Cox regression. Results:The 1-year, 2-year and 3-year cumulative survival rates in RDW high level group were 34.5%, 14.1% and 6.3%, respectively, while those in RDW low level group were 64.3%, 38.6% and 21.4%, respectively, with significant difference ( χ2=23.09, P<0.001). Compared with the low level group, the levels of aspartate aminotransferase and total bilirubin were higher, the levels of albumin, hemoglobin and lipoprotein a were lower, the proportion of portal vein cancer thrombin was higher, and the stage of BCLC was later, with statistical significance (all P<0.05). Cox regression analysis showed that HCC patients with RDW≥13.1%( HR=1.732, 95% CI: 1.223-2.452, P=0.002) had poor survival prognosis after TACE. Conclusion:Preoperative RDW≥13.1% is an independent risk factor for survival after TACE in patients with HCC. RDW has potential predictive value for prognosis of patients with HCC.

ObjectiveTo evaluate the efficacy and safety of first-line transcatheter arterial chemoembolization (TACE) combined with targeted therapy and immunotherapy in the treatment of patients with stage Ⅱb/Ⅲa hepatocellular carcinoma (HCC) based on China Liver Cancer Staging (CNLC). MethodsA total of 198 patients who received first-line TACE combined with targeted therapy and immunotherapy or received TACE alone from January 2015 to December 2022 in the First Affiliated Hospital of Soochow University were enrolled in this study, and after propensity score matching, there were 50 patients in combination group and 50 patients in TACE group. The Kaplan-Meier method was used to calculate median overall survival (mOS) and median progression-free survival (mPFS). Modified Response Evaluation Criteria in Solid Tumors was used to evaluate objective response rate (ORR) and disease control rate (DCR), and Common Terminology Criteria for Adverse Events v5.0 was used to evaluate adverse events. The chi-square test was used for comparison of categorical data between two groups; the t-test was used for comparison of normally distributed continuous data between two groups, and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between two groups. The Kaplan-Meier method was used to estimate survival time and calculate 95% confidence interval (CI), and the Log-rank test was used for comparison of mOS and mPFS between two groups. ResultsThe combination group had an mOS of 30.1 months (95%CI: 21.9 — 38.3), and the TACE group had an mOS of 14.5 months (95%CI: 11.0 — 18.0), with a significant difference between the two groups (χ2=17.8, P<0.001); the combination group had an mPFS of 10.3 months (95%CI: 8.8 — 11.8), and the TACE group had an mPFS of 7.1 months (95%CI: 5.8 — 8.4), with a significant difference between the two groups (χ2=10.4, P<0.001). There were significant differences between the combination group and the TACE group in ORR (84% vs 58%, P<0.05) and DCR (94% vs 80%, P<0.05). There was no significant difference between the combination group and the TACE group in the incidence rate of adverse events (24% vs 16%, P=0.317), and no adverse event-related deaths were observed in either group. ConclusionCompared with TACE alone, TACE combined with targeted therapy and immunotherapy has a better efficacy in the treatment of patients with CNLC stage Ⅱb/Ⅲa HCC, without increasing the incidence rate of severe adverse events.

Objective:To study the risk factors of patients with hepatocellular carcinoma (HCC) to transcatheter arterial chemoembolization(TACE) refractoriness.Methods:The clinical data of 106 HCC patients who underwent TACE at the Affiliated Hospital of Xuzhou Medical University from January 2020 to December 2021 were retrospectively studied. There were 90 males and 16 females, with the age of (59.9±9.3) years. These patients were divided into the TACE-refractory group ( n=47) and the control group ( n=59) based on whether TACE refratoriness occurred after surgery. Serum alpha-fetoprotein (AFP), protein induced by vitamin K absence or antagonist-II (PIVIKA-II), maximum diameter of tumor, number of tumor and tumor vascularization patterns between the two groups were compared. Multivariate logistic regression analysis was performed to analyse the risk factors of TACE refractoriness in patients with HCC after TACE. Results:The proportion of patients with AFP >400 μg/L, PIVIKA-II >40 AU/L, number of tumor and tumor vascularization patterns Ⅲ+ Ⅳ (uneven enhancement) were significantly higher in the TACE-refractory group than the control group (all P<0.05). The maximum diameter of tumor for patients in the TACE-refractory group was significantly larger than that in the control group ( Z=-2.41, P=0.016). Multivariate logistic regression analysis showed that patients with serum AFP >400 μg/L( OR=2.707, 95% CI: 1.008-7.271), multiple tumors ( OR=6.069, 95% CI: 2.115-17.415) and tumor vascularization patterns Ⅲ+ Ⅳ (uneven enhancement)( OR=7.813, 95% CI: 2.246-27.176) before the first TACE were at increased risks of TACE refractoriness (all P<0.05). Conclusion:Preoperative AFP >400 μg/L, multiple tumors and tumor vascularization patterns Ⅲ+ Ⅳ were independent risk factors for TACE refractoriness in patients with HCC.

Objective:To analyze the risk factors of short-term recurrence of hepatocellular carcinoma (HCC) treated by transcatheter arterial chemoembolization combined with radiofrequency ablation (TACE-RFA), and to predict the short-term recurrence rate by establishing a nomogram model.Methods:The clinical data of patients with hepatocellular carcinoma treated with TACE-RFA at the PLA General Hospital from January 2010 to December 2019 were retrospectively analyzed. Of 125 patients who were included, there were 103 males and 22 females, aged (56.6±8.9) years old. Based on whether tumors had recurred within 12 months after treatment, the patients were divided into two groups: the recurrent group ( n=86) and the non-recurrent group ( n=39). The baseline conditions, tumor characteristics and preoperative laboratory examination resultss were collected and the patients were followed-up by outpatient reexaminations. Multivariate logistic regression analysis was used to study the risk factors of short-term recurrence. C-index, correction model and ROC curve were used to evaluate the model. Results:Multivariate logistics regression analysis showed that the neutrophil to lymphocyte ratio (NLR) >1.25 ( OR=2.87, P=0.048), albumin-γ-glutamyltransferase ratio (AGR)≤0.3 ( OR=3.40, P=0.043), incomplete tumor encapsulation ( OR=3.81, P=0.007) and maximum tumor diameter ( OR=1.98, P=0.003) were independent risk factors for short-term recurrence after TACE-RFA. Applying the above factors to construct the nomograph, the C-index was 0.767, the area under the curve was 0.77 (95% CI: 0.67-0.85), and the calibration curve had a good consistency. Conclusion:NLR>1.25, AGR≤0.3, incomplete tumor encapsulation and tumor maximum diameter were risk factors of short-term recurrence after TACE-RFA in patients with HCC. The nomogram model based on the above factors was of good value in predicting short-term recurrence after TACE-RFA.

Objective:To investigate the expression of anti apoptosis inhibitor antibody in serum of patients with advanced primary liver cancer and its relationship with the prognosis after transcatheter hepatic arterial chemoembolization (TACE).Methods:One hundred and three patients with advanced primary liver cancer were selected from our hospital and treated with TACE. Serum anti-survivin antibody expression levels were detected 1 day before surgery and 1 month after surgery. To analyze the relationship between serum anti-survivin antibody level and short-term therapeutic effect, clinicopathological features and prognosis were analyzed.Results:the level of anti-survivin antibody in patients with disease remission was significantly lower than that in patients without disease remission (81.84±9.30 vs. 90.84±10.21, P<0.05), and the change of anti-survivin antibody in patients with disease remission was significantly higher than that in patients without disease remission (30.93±5.63 vs. 22.75±4.52, P<0.05). The changes of anti-survivin antibody before and after TACE were correlated with TNM stage, maximum tumor diameter and degree of differentiation ( P<0.05). The results of survival analysis showed that the postoperative survival of patients with △ reduced anti-survivin antibody was significantly better than that of patients without △ reduced anti-survivin antibody ( P<0.05). The area under the ROC curve was 0.850 in the prediction of one-year death value of patients with primary liver cancer by △ anti-survivin antibody. Conclusion:the difference of anti survivin antibody before and after TACE in patients with advanced liver cancer is closely related to the short-term and long-term prognosis.

According to the International Agency for Research on Cancer (IARC) of the World Health Organization, the number of people with primary liver cancer is predicted to exceed 1 million per year by 2025, making it a major threat to human life and health. According to "Standardization for Diagnosis and Treatment of Hepatocellular Carcinoma (2022 edition) " issued by the National Health Commission of China, locoregional interventional therapy represented by ablation and transcatheter arterial chemoembolization (TACE) has become the main treatment for unresectable intermediate-advanced hepatocellular carcinoma (HCC), in which the indications for TACE include patients with stage Ⅰb to Ⅲb HCC. Locoregional interventional therapy has been proved to have a clear immune activation effect, and with the gradual promotion of immune checkpoint inhibitors in clinical trials and applications at home and abroad, the combination therapy of locoregional intervention and immune checkpoint inhibitors has shown a more effective objective response rate, slower progression time and longer survival, bringing new hope to patients with inoperable intermediate-advanced HCC.

Transcatheter arterial chemoembolization (TACE) is recommended by domestic and international guidelines for the treatment of patients with unresectable hepatocellular carcinoma (uHCC), and it is one of the most common treatment methods for patients with uHCC. The chemotherapy drugs commonly used in TACE for HCC include epirubicin, cisplatin, and fluorouracil, while it is still unclear which chemotherapy drug has a better clinical effect. This article summarizes the studies of different TACE regimens using different chemotherapy drugs in the treatment of patients with uHCC in the recent five years. TACE combined with sorafenib can significantly improve the survival of patients with advanced HCC and has been recommended for the treatment of such patients by Chinese Society of Clinical Oncology guidelines, and the efficacy of TACE combined with other tyrosine kinase inhibitors (TKI) has become a research hotspot. Studies have shown that compared with TACE combined with sorafenib in the treatment of patients with advanced HCC, TACE combined with lenvatinib can achieve a significantly longer progression-free survival time and a tendency of increase in median overall survival time. However, due to the variation of target receptors or downstream signals, resistance to molecular-targeted agents is still a challenging problem. TKI combined with immune checkpoint inhibitors may be a promising strategy for the treatment of patients with uHCC. Some studies suggest that triple therapy using TACE combined with TKIs and anti-PD-1/PD-L1 monoclonal antibody has better efficacy in improving the survival of patients with uHCC. This article reviews the studies of the efficacy and safety of TACE combined with targeted agents and TACE combined with anti-PD-1/PD-L1 monoclonal antibody in the treatment of patients with uHCC in the recent five years.

ABSTRACT Objective To describe the radiological characteristics of hepatocellular carcinoma (HCC) lesions that achieved a complete response following drug-eluting bead transarterial chemoembolization (DEB-TACE) preceding liver transplantation. Methods This single-center case-control study enrolled patients with hepatocellular carcinoma who underwent neoadjuvant DEB-TACE therapy, were followed up with contrast-enhanced magnetic resonance imaging or computed tomography, and were successively evaluated according to the modified Response Evaluation Criteria in Solid Tumors. The HCCs were divided into two groups based on their diameter (Group A: ≤3cm; Group B: 3cm). Viability was assessed using the Kaplan-Meier method according to tumor size categories. The relationship between tumor variables was analyzed using bivariate Cox regression. Results Three-hundred and twenty-eight patients with 667 hepatocellular carcinomas who underwent their first DEB-TACE session were enrolled. A total of 105 hepatocellular carcinomas in 59 patients exhibited complete response after the initial DEB-TACE session and were divided into Group A (92 HCCs) and Group B (13 HCCs). The diameter in Group A decreased significantly compared to the pre-procedure size until the second assessment (p<0.001), with no subsequent reduction in diameter, despite maintaining a complete response. In Group B, the reduction in diameter remained significant compared with the initial value until the sixth imaging evaluation (p=0.014). The average reduction was 45.1% for Group B and a maximum of 14.9% in Group A. Conclusion HCCs >3cm exhibited a greater reduction in size and a longer time to recurrence. HCCs ≤3cm had a shorter relapse time. The recurrence rates were similar. These findings may aid in planning for liver transplantation.
