Intrahepatic cholangiocellular carcinoma (ICC) is a primary tumor originating from the epithelial cells of bile duct. In recent years, incidence of ICC in the world is on the rise, and it has become the second common malignant tumors of the liver, with its incidence being next only to hepatocellular carcinoma (HCC). The onset of ICC is insidious, its clinical manifestations are lack of specificity, most of the patients are already in the advanced stage when the diagnosis is confirmed, thus, affecting the treatment and prognosis. Therefore, early diagnosis and treatment is essential. The radical treatment plan is mainly surgical excision, and other treatment options include systemic chemotherapy, local ablation, transcatheter arterial chemoembolization (TACE), selective intraarterial radiotherapy with yttrium-90 microspheres (SIRT-90Y), 125I seed implantation, etc. This article aims to make a comprehensive introduction about the recent advances in the diagnosis and treatment of ICC.

Objective To construct and validate a predictive model based on preoperative inflammatory biomarkers,and to evaluate its ability in predicting the prognosis of patients with unresectable hepatocellular carcinoma(HCC)after receiving transcatheter arterial chemoembolization(TACE).Methods A total of 544 patients with HCC,who received TACE as the initial treatment at six medical institutions between January 2007 and December 2020,were retrospectively collected.The patients were divided into training cohort(n=376)and validation cohort(n=168).LASSO algorithm and Cox regression analysis were used to screen out the independent influencing factors and to make modelling.The model was validated based on the discrimination,calibration and clinical applicability,and the Kaplan-Meier risk stratification curves were plotted to determine the prognostic differences between groups.The likelihood ratio chi-square value,R2 value,akaike information criterion(AIC)value,C-index and AUROC value of the model were calculated to determine its accuracy and efficiency.Results The training cohort and validation cohort had 376 participants and 168 participants respectively.Multivariate analysis indicated that BCLC,tumor size,number of tumor lesions,neutrophil and prognostic nutritional index(PNI)were the independent influencing factors for postoperative overall survival(OS),with all P being＜0.05;the BCLC grade,tumor size,number of tumor lesions,NLR,PNI and PS score were the independent influencing factors for progression-free survival(PFS),with all P being＜0.05.The C-indexes of the OS and PFS models were 0.735(95％ CI=0.708-0.762)and 0.736(95％ CI=0.711-0.761)respectively,and the external validation was 0.721(95％ CI=0.680-0.762)and 0.693(95％ CI=0.656-0.730)respectively.Ideal discrimination ability of the nomogram was exhibited in time-dependent C-index,time-dependent ROC,and time-dependent AUC.The calibration curves significantly coincided with the ideal standard lines,indicating that the model had high stability and low over-fitting level.Decision curve analysis revealed that there was a wider range of threshold probabilities and it could augment net benefits.The Kaplan-Meier curves for risk stratification indicated that the prognosis of patients varied dramatically between risk categories(P＜0.000 1).The Kaplan-Meier curves for risk stratification indicated that the prognosis of patients varied dramatically among different risk groups(P＜0.000 1).The likelihood ratio chi-square value,R2 value,AIC value,C-index and AUROC value of the model were better than those of other models commonly used in clinical practice.Conclusion The newly-developed prognostic nomogram based on preoperative inflammatory indicators has excellent accuracy as well as excellent prediction effect in predicting the prognosis of patients with unresectable HCC after receiving TACE,therefore,it can be used as an effective tool for guiding individualized treatment and for predicting prognosis.(J Intervent Radiol,2024,33:245-258)

Objective To compare the prognostic ability of Hong Kong Liver Cancer (HKLC) staging system with that of Barcelona Clinic Liver Cancer (BCLC) staging system for Chinese patients with hepatocellular carcinoma (HCC) after receiving transarterial chemoembolization (TACE).Methods The clinical data of 180 Chinese patients with primary HCC,who were treated with TACE during the period from August 2008 to December 2015,were retrospectively analyzed.HCC staging of each patient was scored by two staging methods separately.Kaplan-Meier analysis was adopted to separately calculate the median survival time of each stage that was judged by the two staging methods.The likelihood ratio (LR) x2 values,the Akaike information criterion (AIC) value and Harrell's C value of the two staging methods were calculated.Results Statistically significant differences in the survival time of each period existed between the two staging systems.AIC value,LRx2 value and Harrell's C value of HKLC staging system were 1360,66.6,and 0.813 respectively,while those of BCLC staging system were 1365,61.8,and 0.772 respectively.Conclusion Compared with BCLC staging,HKLC staging is more suitable for predicting the survival time of Chinese patients with primary liver cancer treated with TACE.

ObjectiveTo investigate the efficacy and safety of tyrosine kinase inhibitor （TKI） combined with immune checkpoint inhibitor as the second-line therapy for advanced hepatocellular carcinoma （HCC）. MethodsA retrospective analysis was performed for the clinical data of 63 patients with advanced HCC who were admitted to Department of Interventional Radiology， The First Affiliated Hospital of Soochow University， from January 2018 to December 2022， and all patients experienced progression/intolerance after transcatheter arterial chemoembolization combined with first-line TKI and were switched to second-line TKI with or without immune checkpoint inhibitor. The 32 patients receiving second-line TKI with immune checkpoint inhibitor were enrolled as combination group， and the 31 patients receiving second-line TKI alone were enrolled as single treatment group. Modified Response Evaluation Criteria in Solid Tumors was used to evaluate tumor response， and Common Terminology Criteria for Adverse Events 5.0 was used to evaluate adverse events. The Kaplan-Meier method was used to calculate median overall survival （mOS） and median progression-free survival （mPFS） for the two groups， and the two groups were compared in terms of objective response rate （ORR） and disease control rate （DCR）. The chi-square test was used for comparison of baseline data and follow-up results between groups. ResultsThe median follow-up time was 16.5 （3.2‍ — ‍53.4） months for the 63 patients. The combination group had an mOS of 24.3 （95% confidence interval ［CI］： 20.0‍ — ‍28.6） months and an mPFS of 9.8 （95%CI： 7.5‍ — ‍12.1） months， while the single treatment group had an mOS of 15.8 （95%CI： 11.4‍ — ‍20.1） months and an mPFS of 4.1 （95%CI： 3.2‍ — ‍4.9） months， and there were significant differences in mOS and mPFS between the two groups （P=0.029 and 0.038）. The combination group had an ORR of 47% and a DCR of 84%， while the single treatment group had an ORR of 19% and a DCR of 65%； there was a significant difference in ORR between the two groups （P=0.021）， but with no significant difference in DCR between the two groups （P=0.070）. As for adverse events， 4 patients （12.5%） in the combination group and 3 （10.0%） in the single treatment group experienced grade Ⅲ‍ — ‍Ⅳ serious adverse events， with no fatal drug reactions in either group， and there was no significant difference in the incidence rate of adverse events between the two groups （P=0.783）. ConclusionCompared with TKI alone， TKI combined with immune checkpoint inhibitor has a more significant therapeutic effect as the second-line therapy for advanced HCC， without increasing serious adverse reactions.

Objective To investigate the efficacy and safety of transarterial chemoembolization (TACE) combined with camrelizumab and apatinib in the treatment of advanced hepatocellular carcinoma (HCC). Methods From July 2019 to June 2021, 19 patients with advanced HCC who met the inclusion and exclusion criteria in the First Affiliated Hospital of Soochow University were enrolled in this study. All patients received TACE combined with camrelizumab and apatinib. Tumor response was assessed according to Modified Response Evaluation Criteria in Solid Tumors (mRECIST), and adverse events were assessed according to Common Terminology Criteria for Adverse Events (v5.0). The Kaplan-Meier method was used to analyze progression-free survival and overall survival and calculate 95% confidence interval (CI). Results The median follow-up time was 14.0 months for the 19 patients. As of the last follow-up based on mRECIST, 7 patients (7/19, 36.8%) achieved complete response, 9 (9/19, 47.4%) achieved partial response, and 2 (2/19, 10.5%) achieved stable disease. During follow-up, overall objective response rate and overall disease control rate reached 84.2% and 94.7%, respectively; the median duration of response reached 8.0 (3.4-13.0) months, and median progression-free survival reached 9.5 (95% CI : 4.7-14.3) months; the 6-month survival rate reached 100%, and the 12-month survival rate reached 78.9%. Among the 19 patients, 7 (36.8%) experienced serious adverse events. The most common adverse events of all grades included post-embolization syndrome after TACE (17/19, 89.5%), liver injury (14/19, 73.7%), hematologic toxicity (8/19, 42.1%), and proteinuria (8/19, 42.1%). Conclusion TACE combined with camrelizumab and apatinib has marked efficacy and controllable adverse events in the treatment of advanced HCC, which provides a potential new option for the first-line treatment of advanced HCC.

Transjugular intrahepatic portosystemic shunt (TIPS) is a procedure to establish a portosystemic shunt between the hepatic vein and the portal vein via the jugular approach, so as to reduce portal venous pressure and control acute esophagogastric variceal bleeding (EGVB). The prognosis of EGVB has been improved significantly over the past few decades, and endoscopic variceal ligation combined with drug therapy is now recommended as the first-line treatment regimen for this disease. The latest research advances in the management of EGVB over the past decade have focused on the relatively new concept of "early" or "pre-emptive" TIPS, that is to say, early TIPS (within 72 hours after admission, ideally within 24 hours) is recommended for patients with EGVB who are at a relatively high risk of failure in standard treatment. This article briefly introduces the effect of early TIPS on controlling bleeding, mortality rate, and hepatic encephalopathy, the high-risk population for early TIPS, timing of intervention, cost effectiveness, the applications of early TIPS in a real-world setting, and recommendations for early TIPS in international guidelines and consensus statements.

Transarterial chemoembolization （TACE） is currently the primary treatment method for advanced liver cancer. This article elaborates on the current status of application of TACE in hepatocellular carcinoma from the aspects of existing techniques， patient selection， and efficacy assessment and summarizes the research advances and prospects of TACE combined with local treatment and systemic therapy， so as to provide new ideas for clinical practice and experimental studies.

Intrahepatic cholangiocarcinoma （ICC） is a relatively rare type of primary liver cancer， and its incidence rate has gradually increased in recent years. Due to its insidious onset and atypical clinical symptoms， most patients are already in the advanced stage of the disease at the time of confirmed diagnosis， and therefore， timely diagnosis and treatment are of great importance. Radical surgical resection is the standard treatment regimen for early-stage ICC patients， while systemic chemotherapy is the basic treatment for patients with advanced ICC and is often combined with interventional treatment， targeted therapy， and immunotherapy. This article reviews the advances in the diagnosis and treatment of ICC.

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.
