Methods: The prospective cohort study was conducted, with 81 patients with large hepatocellular carcinoma who were admitted to Jingzhou Central Hospital from 2018 to 2022, they were divided into two groups, 41 patients received TACE sequential MWA combined with targeted therapy and immunotherapy (observation group), and 40 patients received single TACE combined with targeted therapy and immunotherapy (control group). The short-term efficacies after 3 months of treatment, the Disease Control Rate (DCR), the Overall Survival (OS), adverse drug reactions and complications were compared and analyzed between the two groups. Results: The Objective Response Rate (ORR) of the observation group was significantly higher than that of the control group (ORR: 85.4% vs 57.5%, P = 0.005), The median Progression-Free Survival (PFS) and median OS of the observation group were better than those of the control group (mPFS: 16 months vs 10 months, P = 0.004;mOS: 39 months. vs 24 months, P = 0.008). The 1-, 2- and 3-year progression-free survival rates of the observation group were 72.9%, 50.4%, and 25.6%, and those of the control group were 30.4%, 11.0%, and 3.7%. The 1-, 2- and 3-year overall survival rates of the observation group were 78.9%, 71.7%, and 65.2%, and those of the control group were 65.1%, versus 42.1% and 36.9%. There was no significant difference in the incidence of adverse drug reactions and complications between the two groups. In this study, the adverse drug reactions were mild in Grades 1 - 2. Conclusion: TACE sequential MWA combined with targeted therapy and immunotherapy has efficacy and safety.展开更多

Methods Eighty-two patients with hepatocellular carcinoma were randomly divided into the control group and experimental group. On the first day after TACE, the experimental group started receiving four Jinlong capsules orally three times daily, whereas the control group did not receive the treatment.Results The incidences of erythropenia and thrombocytopenia in the experimental group was lower than those in the control group(P = 0.040 and 0.033, respectively). The differences in serum levels of aminotransferase, albumin, potassium, and sodium between the two groups were significant(P = 0.034, 0.034, 0.013, and 0.044, respectively). The mean durations of stomachache and abdominal distension in the experimental group was significantly shorter than those in the control group(P = 0.004 and 0.021, respectively). However, there were no significant differences in the incidences of nausea, fever, and vomiting between the two groups(P = 0.490, 0.495, and 0.585, respectively). Conclusion The reduction in the incidence rate and duration of partial adverse reactions after TACE was observed in hepatocellular carcinoma patients treated with Jinlong capsule compared to untreated patients, suggesting possible beneficial effects exerted by Jinlong capsule on the reduction of TACE-induced liver damage, thereby improving liver function and, consequently, the quality of life.展开更多

Recently, balloon-occluded TACE(B-TACE) was developed in Japan. Despite the lack of a clear definition, B-TACE is generally defined as the infusion of emulsion of chemotherapeutic agents with lipiodol followed by gelatin particles under the occlusion of feeding arteries by a microballoon catheter, which leads to the dense lipiodol emulsion(LE) accumulation in HCC nodules. This phenomenon cannot be explained only by the prevention of proximal migration and leakage of embolization materials; it further involves causing local changes in the hemodynamics of the surrounding occlusion artery and targeted HCC nodules. Balloon-occluded arterial stump pressure plays an important role in the dense LE accumulation in targeted HCC nodules. Although randomized controlled trials comparing the therapeutic effect and the prognosis of B-TACE to those of the other TACE procedures, such as conventional-TACE and drug-eluting beads TACE, are still lacking, B-TACE is thought to be a promising treatment. The purpose of this review is to summarize the mechanism, therapeutic effect, indication, prognosis and complications of BTACE.展开更多

Univariate and multivariate analyses were performed to investigate the risk factors for recurrence-free survival(RFS) and overall survival(OS). Multiple logistic regression was used to identify the clinicopathological characteristics associated with MVI. The rates of RFS and OS were compared among patients with or without MVI treated with liver resection alone or followed by PA-TACE. RESULTS Univariate and multivariate analyses demonstrated that serum AFP level > 400 ng/m L, tumor size > 5 cm, tumor capsule invasion, MVI, and major hepatectomy were risk factors for poor OS. Tumor capsule invasion, MVI, tumor size > 5 cm, HBV-DNA copies > 1 x 104 IU/m L, and multinodularity were risk factors for poor RFS. Multiple logistic regression identified serum AFP level > 400 ng/m L, tumor size > 5 cm, and tumor capsule invasion as independent predictors of MVI. Both OS and DFS were significantly improved in patients with MVI who received PA-TACE as compared to those who underwent liver resection alone. Patients without MVI did not show a significant difference in OS and RFS between those treated by liver resection alone or followed by PA-TACE.CONCLUSION PA-TACE is a safe adjuvant intervention and can efficiently prevent tumor recurrence and improve the survival of BCLC early-and intermediate-stage HCC patients with MVI.展开更多

This study was designedto investigate the association between changes in plasmaVEGF levels after transcatheter arterial chemoembolization(TACE) and HCC progression, especially in relation tometastasis.METHODS: Plasma VEGF levels were measured by quati-tative sandwich enzyme-linked immunosorbent assay(ELISA R&D system). Plasma VEGF levels were measuredbefore, 3 days and 4 weeks after TACE in 30 patients withHCC. The development of metastasis was evaluated at theend of the third month after TACE.RESULTS: The plasma VEGF levels of the 30 patients withHCC were 154.47±90.17 pg/ml. The total plasma VEGFlevels after TACE increased compared with their basal levels(P<0.05), and the plasma VEGF levels had a tendency toincrease in patients with heterogenous uptake of iodizdoiland portal vein thrombosis. Follow-up for six monthsshowed metastatic foci in 20 patients (74%) with increasedplasma VEGF, but none of the patients with decreased plas-ma VEGF developed metastasis.CONCLUSION: Increased plasma VEGF expression is asso-ciated with the development of metastasis in HCC after TA-CE.展开更多

However, 60%-70% of patients have lost the chance of surgery at the time of diagnosis. Simple biliary stent or drainage tube placement may fail in a short time due to tumor invasion or overgrowth, bile accumulation, or biofilm formation. Effective palliative treatments to extend the effective drainage time are of great significance for improving the quality of life of patients and changing the prognosis of patients. AIM To investigate the clinical efficacy of gemcitabine and cisplatin-based transcatheter arterial chemoembolization (TACE) combined with radiotherapy in hilar cholangiocarcinoma.METHODS A retrospective analysis was conducted on patients clinically diagnosed with hilar cholangiocarcinoma from June 2014 to January 2017 at the Liaoning Provincial Cancer Hospital. Patients were evaluated by specialists, and those who were not suitable for surgery or unwilling to undergo surgery and met the inclusion criteria were included in the study. There were a total of 72 patients (34 males and 38 females) with an average age of 59.9 years (range, 40-72 years). According to percutaneous transhepatic biliary angiography and the patients’ wishes, stent implantation or biliary drainage tube implantation was used to relieve biliary obstruction. The patients were divided into either a control group or a combined treatment group according to their follow-up treatment. The control group consisted of a total of 35 patients who received simple biliary drainage tube placement and biliary stent implantation (7 patients with bilateral stents and 6 with a unilateral stent) and 22 patients receiving biliary drainage tube placement alone. The combined treatment group received TACE and extracorporeal radiotherapy after biliary drainage or biliary stent implantation and consisted of a total of 37 patients, including 21 patients receiving combined treatment after biliary stent placement (14 patients with bilateral stents and 7 with a unilateral stent) and 16 undergoing combined therapy after implanting the biliary drainage tube. In the combination treatment group, the TACE chemotherapy regimen employed gemcitabine and cisplatin, and the embolic agent was iodized oil. A particular dose was determined according to the patient's body surface area and the tumor staining indicated by DSA. In vitro radiotherapy was performed with intensity-modulated radiotherapy or threedimensional conformal radiotherapy at an average dose of 48.3 Gy. Both groups were followed from stent implantation or drainage tube implantation until the patient quitted or died. The median length of follow-up observation was 13 mo. The differences in overall survival time and the effect of different jaundice reducing methods (single stent, double stent, or biliary drainage) on the patency time and survival time of biliary stents were compared between the two groups;the related factors affecting overall survival time were analyzed. RESULTS The median survival time of the control group was 10.5 mo;the median survival time of patients with biliary stent implantation and those with percutaneous biliary drainage was 9.6 mo and 11.4 mo, respectively, and there was no statistically significant difference between them. The median survival time of the combined treatment group was 20.0 mo, which was significantly higher than that of the control group (P < 0.05). Among patients in the combined treatment group, the median survival time of patients who underwent biliary stent implantation and those who accepted percutaneous biliary drainage before the combination therapy was 19.5 mo and 20.1 mo, respectively, and there was no significant difference between them. In the combination treatment group, the mean time of median stent patency was 15.6 mo, which was significantly higher than that of the control group (7.0 mo;P < 0.05). The independent factors affecting survival time included age, whether to receive combination therapy, percutaneous biliary drainage tube implantation, and Bismuth-Corlette classification as type IV. CONCLUSION Gemcitabine and cisplatin-based TACE combined with radiotherapy can prolong the survival of patients with hilar cholangiocarcinoma. Independent predictors of survival include selection of combination therapy, Bismuth-Corlette classification as type IV, selection of percutaneous biliary drainage tube implantation, and age.展开更多

But this method has some shortages. p53 gene, which was found to be mutant in many human tumors, has been proved with broadspectrum anti-tumor effects. We reported a 23-year-old patient with recurrent HCC after irregular hepatectomy. The p53 gene was applied to this patient. We injected percutaneously and infused transcatheterally p53 gene (Gendicine, Shenzhen Sibiono Bentech, China) into his recurrent nodules in liver respectively and 4 d later, the patient received TACE therapy. In the 2 mo follow-up, the patient was in good clinical condition with normal liver function and no recurrence was identified. The case report proposed that recurrent HCC could be successfully treated with p53 gene therapy combining TACE.展开更多

Adopting either as a first-line therapy carries major cost and resource implications. The objective of this study was to estimate the relative cost-effectiveness of TACE against TACE-sorafenib for unresectable HCC using a decision analytic model.METHODS: A Markov cohort model was developed to compare TACE and TACE-sorafenib. Transition probabilities and utilities were obtained from systematic literature reviews, and costs were obtained from West China Hospital, Sichuan University, China. Survival benefits were reported in quality-adjusted life-years(QALYs). The incremental cost-effectiveness ratio(ICER) was calculated. Sensitive analysis was performed by varying potentially modifiable parameters of the model.RESULTS: The base-case analysis showed that TACE cost $26 951 and yielded survival of 0.71 QALYs, and TACE-sorafenib cost $44 542 and yielded survival of 1.02 QALYs in the entire treatment. The ICER of TACE-sorafenib versus TACE was $56 745 per QALY gained, which was above threshold for cost-effectiveness in China. Sensitivity analysis revealed that the major driver of ICER was the cost post TACE-sorafenib therapy with stable state.CONCLUSION: TACE is a more cost-effective strategy than TACE-sorafenib for the treatment of unresectable HCC.展开更多

It decreases after surgical resection, and resumes upon recurrence, indicating a potential indicator for the effectiveness of the treatment. But changes of GP73 after transcatheter arterial chemoemboliza- tion (TACE) have not been reported so far. This study was to investigate the dynamic changes of GP73 in HCC patients af- ter TACE treatment, and the possible underlying mechanisms in the cell cultures. METHODS: Blood samples were collected from 72 HCC pa- tients, before TACE, at day I and day 30 after TACE. GP73 lev- els were measured by Western blotting. The dynamic changes of GP73 were analyzed and compared with image changes and clinical data. The effects of chemotherapeutic agents (5-FU and pirarubicin) on GP73 expression were tested in three HCC cell lines (HepG2, HCCLM3 and MHCC97H). RESULTS: The GP73 level was significantly elevated at day 1 and day 30 after TACE in HCC patients compared with that before the procedure (P〈0.05). There was no statistical differ- ence between the two time points after TACE, nor correlationbetween GP73 levels and dinicopathological features, tumor metastasis, and patient survival. Pirarubicin, not 5-FU, signifi- cantly increased GP73 expression in three cell lines. CONCLUSIONS: Unlike surgical resection which decreases the GP73 level, TACE significantly increased GP73 expression in patients with HCC. No correlations were observed among GP73 levels, tumor characteristics and prognosis of patients with HCC.展开更多

文摘BACKGROUND Hepatocellular carcinoma(HCC)patients complicated with portal vein tumor thrombus(PVTT)exhibit poor prognoses and treatment responses.AIM To investigate efficacies and safety of the combination of PD-1 inhibitor,transcatheter arterial chemoembolization(TACE)and Lenvatinib in HCC subjects comorbid with PVTT.METHODS From January 2019 to December 2020,HCC patients with PVTT types Ⅰ-Ⅳ were retrospectively enrolled at Beijing Ditan Hospital.They were distributed to either the PTL or TACE/Lenvatinib(TL)group.The median progression-free survival(mPFS)was set as the primary endpoint,while parameters like median overall survival,objective response rate,disease control rate(DCR),and toxicity level served as secondary endpoints.RESULTS Forty-one eligible patients were finally recruited for this study and divided into the PTL(n=18)and TL(n=23)groups.For a median follow-up of 21.8 months,the DCRs were 88.9%and 60.9%in the PTL and TL groups(P=0.046),res-pectively.Moreover,mPFS indicated significant improvement(HR=0.25;P<0.001)in PTL-treated patients(5.4 months)compared to TL-treated(2.7 months)patients.There were no treatment-related deaths or differences in adverse events in either group.CONCLUSION A triplet regimen of PTL was safe and well-tolerated as well as exhibited favorable efficacy over the TL regimen for advanced-stage HCC patients with PVTT types Ⅰ-Ⅳ.
文摘BACKGROUND Transarterial chemoembolization(TACE)is a standard treatment for intermediate-stage hepatocellular carcinoma(HCC).The complications of TACE include biliary tract infection,liver dysfunction,tumor lysis syndrome,biloma,partial intestinal obstruction,cerebral lipiodol embolism,etc.There are few reports about tracheal fistula induced by TACE.CASE SUMMARY A 42-year-old man came to our hospital with cough and expectoration for 1 month after TACE for HCC.Laboratory test results showed abnormalities of albumin,hemoglobin,prothrombin time,C-reactive protein,D-dimer,and prothrombin.Culture of both phlegm and liver pus revealed growth of Citrobacter flavescens.Computed tomography showed infection in the inferior lobe of the right lung and a low-density lesion with gas in the right liver.Liver ultrasound showed that there was a big hypoechoic liquid lesion without blood flow signal.Drainage for liver abscess by needle puncture under ultrasonic guidance was performed.After 1 month of drainage and anti-infection therapy,the abscess in the liver and the infection in the lung were reduced obviously,and the symptom of expectoration was relieved.CONCLUSION Clinicians should be alert to the possibility of complications of liver abscess and tracheal fistula after TACE for HCC.Drainage for liver abscess by needle puncture under ultrasonic guidance could relieve the liver abscess and tracheal fistula.
文摘BACKGROUND Enhanced magnetic resonance imaging(MRI)is widely used in the diagnosis,treatment and prognosis of hepatocellular carcinoma(HCC),but it can not effectively reflect the heterogeneity within the tumor and evaluate the effect after treatment.Preoperative imaging analysis of voxel changes can effectively reflect the internal heterogeneity of the tumor and evaluate the progression-free survival(PFS).AIM To predict the PFS of patients with HCC before operation by building a model with enhanced MRI images.METHODS Delineate the regions of interest(ROI)in arterial phase,portal venous phase and delayed phase of enhanced MRI.After extracting the combinatorial features of ROI,the features are fused to obtain deep learning radiomics(DLR)_Sig.DeLong's test was used to evaluate the diagnostic performance of different typological features.K-M analysis was applied to assess PFS in different risk groups,and the discriminative ability of the model was evaluated using the Cindex.RESULTS Tumor diameter and diolame were independent factors influencing the prognosis of PFS.Delong's test revealed multi-phase combined radiomic features had significantly greater area under the curve values than did those of the individual phases(P<0.05).In deep transfer learning(DTL)and DLR,significant differences were observed between the multi-phase and individual phases feature sets(P<0.05).K-M survival analysis revealed a median survival time of high risk group and low risk group was 12.8 and 14.2 months,respectively,and the predicted probabilities of 6 months,1 year and 2 years were 92%,60%,40%and 98%,90%,73%,respectively.The C-index was 0.764,indicating relatively good consistency between the predicted and observed results.DTL and DLR have higher predictive value for 2-year PFS in nomogram.CONCLUSION Based on the multi-temporal characteristics of enhanced MRI and the constructed Nomograph,it provides a new strategy for predicting the PFS of transarterial chemoembolization treatment of HCC.
文摘Objective: To investigate the safety and efficacy of Transcatheter Arterial Chemoembolization (TACE), sequential Microwave Ablation (MWA) combined with targeted therapy and immunotherapy versus TACE combined with targeted therapy and immunotherapy in the treatment of large hepatocellular carcinoma (defined as tumor diameter > 5 cm). Methods: The prospective cohort study was conducted, with 81 patients with large hepatocellular carcinoma who were admitted to Jingzhou Central Hospital from 2018 to 2022, they were divided into two groups, 41 patients received TACE sequential MWA combined with targeted therapy and immunotherapy (observation group), and 40 patients received single TACE combined with targeted therapy and immunotherapy (control group). The short-term efficacies after 3 months of treatment, the Disease Control Rate (DCR), the Overall Survival (OS), adverse drug reactions and complications were compared and analyzed between the two groups. Results: The Objective Response Rate (ORR) of the observation group was significantly higher than that of the control group (ORR: 85.4% vs 57.5%, P = 0.005), The median Progression-Free Survival (PFS) and median OS of the observation group were better than those of the control group (mPFS: 16 months vs 10 months, P = 0.004;mOS: 39 months. vs 24 months, P = 0.008). The 1-, 2- and 3-year progression-free survival rates of the observation group were 72.9%, 50.4%, and 25.6%, and those of the control group were 30.4%, 11.0%, and 3.7%. The 1-, 2- and 3-year overall survival rates of the observation group were 78.9%, 71.7%, and 65.2%, and those of the control group were 65.1%, versus 42.1% and 36.9%. There was no significant difference in the incidence of adverse drug reactions and complications between the two groups. In this study, the adverse drug reactions were mild in Grades 1 - 2. Conclusion: TACE sequential MWA combined with targeted therapy and immunotherapy has efficacy and safety.
文摘BACKGROUND Primary hepatic carcinoma(PHC)has an insidious onset and is usually diagnosed in the middle and late stages.Although transcatheter arterial chemoembolization(TACE)is the preferred option for treating middle-and advanced-stage PHC,it has limited efficacy in killing tumor cells and poor long-term efficacy.TACE plus percutaneous microwave coagulation therapy(PMCT)is more effective than interventional therapy alone and can improve survival time.However,there are few reports on the effects of TACE and PMCT on serum marker levels and the prognosis of patients with advanced PHC.AIM To investigate the effect of PMCT+TACE on serum tumor markers and the prognosis of middle-late PHC.METHODS This retrospective study included 150 patients with middle-late PHC admitted to Zhongshan People’s Hospital between March 2018 and February 2021.Patients were divided into a single group(treated with TACE,n=75)and a combined group(treated with TACE+PMCT,n=75).Before and after treatment,the clinical efficacy and serum tumor marker levels[carbohydrate antigen 19-9(CA19-9),alpha-fetoprotein(AFP),and carcinoembryonic antigen(CEA)]of both groups were observed.The 1-year survival rates and prognostic factors of the two groups were analyzed.RESULTS The combined group had 21 and 35 cases of complete remission(CR)and partial remission(PR),respectively.The single group had 13 and 25 cases of CR and PR,decreased,with the decrease in the combined group being more significant(P<0.05).The 1-year survival rate of the combined group(80.00%)was higher than that of the single group(60.00%)(P<0.05).The average survival time within 1 year in the combined group was 299.38±61.13 d,longer than that in the single group(214.41±72.97 d,P<0.05).COX analysis revealed that tumor diameter,tumor number,and the treatment method were prognostic factors for patients with middle-late PHC(P<0.05).CONCLUSION TACE+PMCT is effective in treating patients with mid-late PHC.It reduces the levels of tumor markers,prolongs survival,and improves prognosis.
文摘The purpose of this study was to evaluate the outcome of patients with unresectable hepatocellular carcinoma(HCC) treated by sequential therapy of transcatheter arterial chemoembolization(TACE),three-dimensional conformal radiotherapy(3-DCRT) and high-intensity focused ultrasound(HIFU).From October,2005 to September,2010,120 patients with unresectable HCC received the sequential treatments of several courses of TACE followed in 2-4 weeks by 3-DCRT and then a single session of HIFU with a curative intent.The median tumor irradiation dose was 40 Gy.Tumor response,toxicity and overall survival rate were analyzed.Clinicopathologic factors affecting the primary technique effectiveness and overall survival rates were investigated by univariate analysis or multivariate analysis.All 120 HCC patients were followed up by the last follow-up time.Among these patients,hepatic toxicities due to treatment were notable in 9 cases.Gastrointestinal bleeding after the overall treatment occurred in 2 cases,leukopenia of grade III was detected in 1 case,radiation-induced liver disease(RILD) was observed in 2 patients,and first-and second-degree skin burn around the HIFU treatment zone were observed in 2 patients and 1 patient,respectively.Among 120 patients,23,83 and 14 cases achieved partial response,stable disease and progressive disease,respectively.The overall survival rates at 1 year,3 years and 5 years were 70%,35% and 15%,respectively,with a median survival time of 26 months.Both Child-Pugh liver function grading and radiation dose were determined to be independent predictors for overall survival revealed by the multivariate analysis.It is concluded that the sequential therapy of TACE,3-DCRT and HIFU is a promising therapeutic regimen for unresectable HCC.
文摘BACKGROUND Pain after transcatheter arterial chemoembolisation(TACE)can seriously affect the prognosis of patients and the insertion of additional medical resources.AIM To develop an early warning model for predicting pain after TACE to enable the implementation of preventive analgesic measures.METHODS We retrospectively collected the clinical data of 857 patients(from January 2016 to January 2020)and prospectively enrolled 368 patients(from February 2020 to October 2022;as verification cohort)with hepatocellular carcinoma(HCC)who received TACE in the Hepatic Surgery Center of Tongji Hospital.Five predictive models were established using machine learning algorithms,namely,random forest model(RFM),support vector machine model,artificial neural network model,naive Bayes model and decision tree model.The efficacy of these models in predicting postoperative pain was evaluated through receiver operating characteristic curve analysis,decision curve analysis and clinical impact curve analysis.RESULTS A total of 24 candidate variables were included in the predictive models using the iterative algorithms.Age,preoperative pain,number of embolised tumours,distance from the liver capsule,dosage of iodised oil and preoperative prothrombin activity were closely associated with postoperative pain.The accuracy of the predictive model was compared between the training[area under the curve(AUC)=0.798;95%confidence interval(CI):0.745-0.851]and verification(AUC=0.871;95%CI:0.818-0.924)cohorts,with RFM having the best predictive efficiency(training cohort:AUC=0.869,95%CI:0.816-0.922;internal verification cohort:AUC=0.871;95%CI:0.818-0.924).CONCLUSION The five predictive models based on advanced machine learning algorithms,especially RFM,can accurately predict the risk of pain after TACE in patients with HCC.RFM can be used to assess the risk of pain for facilitating preventive treatment and improving the prognosis.

文摘Objective The aim of this study was to analyze whether Jinlong capsule could decrease adverse reactions after transcatheter arterial chemoembolization(TACE) in patients with hepatocellular carcinoma. Methods Eighty-two patients with hepatocellular carcinoma were randomly divided into the control group and experimental group. On the first day after TACE, the experimental group started receiving four Jinlong capsules orally three times daily, whereas the control group did not receive the treatment.Results The incidences of erythropenia and thrombocytopenia in the experimental group was lower than those in the control group(P = 0.040 and 0.033, respectively). The differences in serum levels of aminotransferase, albumin, potassium, and sodium between the two groups were significant(P = 0.034, 0.034, 0.013, and 0.044, respectively). The mean durations of stomachache and abdominal distension in the experimental group was significantly shorter than those in the control group(P = 0.004 and 0.021, respectively). However, there were no significant differences in the incidences of nausea, fever, and vomiting between the two groups(P = 0.490, 0.495, and 0.585, respectively). Conclusion The reduction in the incidence rate and duration of partial adverse reactions after TACE was observed in hepatocellular carcinoma patients treated with Jinlong capsule compared to untreated patients, suggesting possible beneficial effects exerted by Jinlong capsule on the reduction of TACE-induced liver damage, thereby improving liver function and, consequently, the quality of life.
文摘Objective:To compare radiofrequency ablation (RFA) or microwave ablation (MWA) and transcatheter arterial chemoembolization (TACE) with RFA or MWA monotherapy in hepatocellular carcinoma (HCC).Methods:A prospective,randomized,controlled trial was conducted on 94 patients with HCC ≤7 cm at a single tertiary referral center from June 2008 to June 2010 at the Department of Hepatobiliary Surgery,the Second Affiliated Hospital of Southeast University.The patients were randomly assigned into the TACERFA or TACE-MWA (combined treatment group) and the RFA-alone or MWA-alone groups (control group).The primary end point was overall survival.The secondary end point was recurrence-free survival,and the tertiary end point was adverse effects.Results:Until the time of censor,17 patients in the TACE-RFA or TACE-MWA group had died.The median follow-up time of the patients who were still alive for the TACE-RFA or TACE-MWA group was 47.5±11.3 months (range,29 to 62 months).The 1-,3-and 5-year overall survival for the TACE-RFA or TACE-MWA group was 93.6%,68.1% and 61.7%,respectively.Twenty-five patients in the RFA or MWA group had died.The median follow-up time of the patients who were still alive for the RFA or MWA group was 47.0±12.9 months (range,28 to 62 months).The 1-,3-and 5-year overall survival for the RFA or MWA group was 85.1%,59.6% and 44.7%,respectively.The patients in the TACE-RFA or TACE-MWA group had better overall survival than the RFA or MWA group [hazard ratio (HR),0.526; 95% confidence interval (95% CO,0.334-0.823; P=0.002],and showed better recurrence-free survival than the RFA or MWA group (HR,0.582; 95% CI,0.368-0.895; P=0.008).Conclusions:RFA or MWA combined with TACE in the treatment of HCC ≤7 cm was superior to RFA or MWA alone in improving survival by reducing arterial and portal blood flow due to TACE with iodized oil before RFA.
文摘Objective:Transcatheter arterial chemoembolization (TACE) is a standard treatment for hepatocellular carcinoma (HCC) and/or some unresectable liver metastasis tumors.Hypervascular liver metastatic lesions such as metastasis from gastrointestinal stromal tumor (GIST) are an indication for transcatheter arterial embolization (TAE).The purpose of this study was to evaluate the efficacy and safety of Embosphere(㊣)-TAE (Embo-TAE) in comparison with conventional TACE (cTACE) for the treatment of liver metastasis from GIST.Methods:A total of 45 patients who underwent TACE between Aug 2008 and Feb 2013 were enrolled.Patients with GIST who underwent TAE with Embosphere(㊣) (n=19) were compared with controls who received cTACE (n=26).The primary end points were treatment response and treatment-related adverse events.The secondary end points were progression-free survival (PFS) and overall survival (OS).Results:The treatment response of Embo-TAE group was significandy higher than that of the cTACE group (P<0.001).The PFS was significandy better in the Embosphere(㊣)-group than in the cTACE group (56.6 and 42.1 weeks,respectively; P=0.003).However,there was no statistically significant difference in liver toxicity between the two groups (P>0.05).The median OS in the Embo-TAE group was longer than that in the cTACE group (74.0 weeks,95% CI:68.2-79.8 vs.61.7 weeks,95% CI:56.2-67.2 weeks) (unadjusted P=0.045).The use of Embo-TAE significantly reduced the risk of death in patients with GIST with liver metastases according to the Cox proportonal hazards regression model [hazard ratio (HR):0.149; 95% CI:0.064-0.475].Conclusions:TAE with Embosphcre(㊣) showed better treatment response and delayed tumor progression compared with cTACE.There was no significant difference in treatment-related hepatic toxicities.EmboTAE thus appears to be a feasible and promising approach in the treatment of liver metastasis from GIST.
文摘Transcatheter arterial chemoembolization(TACE) is widely accepted as a treatment for patients with hepatocellular carcinoma(HCC) in the intermediate stage according to the Barcelona Clinic Liver Cancer(BCLC) guidelines. Recently, balloon-occluded TACE(B-TACE) was developed in Japan. Despite the lack of a clear definition, B-TACE is generally defined as the infusion of emulsion of chemotherapeutic agents with lipiodol followed by gelatin particles under the occlusion of feeding arteries by a microballoon catheter, which leads to the dense lipiodol emulsion(LE) accumulation in HCC nodules. This phenomenon cannot be explained only by the prevention of proximal migration and leakage of embolization materials; it further involves causing local changes in the hemodynamics of the surrounding occlusion artery and targeted HCC nodules. Balloon-occluded arterial stump pressure plays an important role in the dense LE accumulation in targeted HCC nodules. Although randomized controlled trials comparing the therapeutic effect and the prognosis of B-TACE to those of the other TACE procedures, such as conventional-TACE and drug-eluting beads TACE, are still lacking, B-TACE is thought to be a promising treatment. The purpose of this review is to summarize the mechanism, therapeutic effect, indication, prognosis and complications of BTACE.

文摘AIM To investigate the efficacy and safety of postoperative adjuvant transcatheter arterial chemoembolization(PA-TACE) in preventing tumor recurrence and improving survival in Barcelona Clinic Liver Cancer(BCLC) early(A) and intermediate(B) stage hepatocellular carcinoma(HCC) patients with microvascular invasion(MVI).METHODS A total of 519 BCLC A or B HCC patients treated by liver resection alone or followed by PA-TACE between January 2012 and December 2015 were studied retrospectively. Univariate and multivariate analyses were performed to investigate the risk factors for recurrence-free survival(RFS) and overall survival(OS). Multiple logistic regression was used to identify the clinicopathological characteristics associated with MVI. The rates of RFS and OS were compared among patients with or without MVI treated with liver resection alone or followed by PA-TACE. RESULTS Univariate and multivariate analyses demonstrated that serum AFP level > 400 ng/m L, tumor size > 5 cm, tumor capsule invasion, MVI, and major hepatectomy were risk factors for poor OS. Tumor capsule invasion, MVI, tumor size > 5 cm, HBV-DNA copies > 1 x 104 IU/m L, and multinodularity were risk factors for poor RFS. Multiple logistic regression identified serum AFP level > 400 ng/m L, tumor size > 5 cm, and tumor capsule invasion as independent predictors of MVI. Both OS and DFS were significantly improved in patients with MVI who received PA-TACE as compared to those who underwent liver resection alone. Patients without MVI did not show a significant difference in OS and RFS between those treated by liver resection alone or followed by PA-TACE.CONCLUSION PA-TACE is a safe adjuvant intervention and can efficiently prevent tumor recurrence and improve the survival of BCLC early-and intermediate-stage HCC patients with MVI.

文摘BACKGROUND: Hypoxia up-regulates vascular endothelialgrowth factor (VEGF) and stimulates the growth of hepa-tocellular carcinoma (HCC) cells. This study was designedto investigate the association between changes in plasmaVEGF levels after transcatheter arterial chemoembolization(TACE) and HCC progression, especially in relation tometastasis.METHODS: Plasma VEGF levels were measured by quati-tative sandwich enzyme-linked immunosorbent assay(ELISA R&D system). Plasma VEGF levels were measuredbefore, 3 days and 4 weeks after TACE in 30 patients withHCC. The development of metastasis was evaluated at theend of the third month after TACE.RESULTS: The plasma VEGF levels of the 30 patients withHCC were 154.47±90.17 pg/ml. The total plasma VEGFlevels after TACE increased compared with their basal levels(P<0.05), and the plasma VEGF levels had a tendency toincrease in patients with heterogenous uptake of iodizdoiland portal vein thrombosis. Follow-up for six monthsshowed metastatic foci in 20 patients (74%) with increasedplasma VEGF, but none of the patients with decreased plas-ma VEGF developed metastasis.CONCLUSION: Increased plasma VEGF expression is asso-ciated with the development of metastasis in HCC after TA-CE.
文摘AIM:To assess the possible effect of two different types of preoperative transcatheter arterial chemoembolization(TACE)on recurrence-free survival after liver transplantation(LT)in patients with hepatocellular carcinoma(HCC)and to analyze the effects of TACE on tumor histology.METHODS:We retrospectively analyzed the histological features of 130 HCC nodules in 63 native livers removed at transplantation.Patients who received any other type of treatment such as radiofrequency tumor ablation,percutaneous ethanol ablation or who were not treated at all were excluded.All patients in the present study were within the Milan Criteria at the last imaging findings before transplantation.Doxorubicineluting bead TACE(DEB-TACE)was performed in 22patients(38 nodules),and conventional TACE(c-TACE)in 16(25 nodules).Patients’and tumors’characteristics were retrospectively reviewed.We performed a pernodule analysis of the explanted livers to establish the mean percentage of necrosis of any nodule treated by TACE(conventional or DEB)and a per-patient analysis to establish the percentage of necrosis in the cumulative tumor area,including 21 nodules not reached by TACE.Inflammatory and fibrotic changes in the tissue surrounding the tumor nodule were analyzed and categorized as poor/absent,moderate and enhanced reaction.Uni-and multivariate analysis of risk factors for HCC-recurrence were performed.RESULTS:The number and diameter of the nodules,the time spent on the waiting list and the number of treatments were similar in the two groups.A trend towards higher appropriate response rates(necrosis≥90%)was observed in the DEB-TACE group(44.7%vs32.0%,P=0.2834).The mean percentage of necrosis in the cumulative tumor area was 58.8%±36.6%in the DEB-TACE group and 50.2%±38.1%in the c-TACE group(P=0.4856).Fibrotic and inflammatory reactions surrounding the tumor nodule were markedly more common in the DEB-TACE group(P<0.0001,for both the parameters).The three-year recurrence-free survival was higher in DEB-TACE-treated patients than in conventionally treated patients(87.4%vs 61.5%,P=0.0493).Other factors affecting recurrence-free survival included viable tumor beyond Milan Criteria on histopathological examination,the percentage of necrosis on CTA≤50%and a pre-transplant serum-fetoprotein level greater than 70 ng/mL.On multivariate analysis,the lack of treatment with DEB-TACE,high levels of-fetoprotein and viable tumor beyond Milan Criteria at histology examination were identified as independent predictors of tumor recurrence.CONCLUSION:DEB-TACE can effectively promote tumor necrosis and improves recurrence-free survival after LT in HCC.
文摘BACKGROUND Radical surgical resection is regarded as the best treatment for hepatic hilar cholangiocarcinoma. However, 60%-70% of patients have lost the chance of surgery at the time of diagnosis. Simple biliary stent or drainage tube placement may fail in a short time due to tumor invasion or overgrowth, bile accumulation, or biofilm formation. Effective palliative treatments to extend the effective drainage time are of great significance for improving the quality of life of patients and changing the prognosis of patients. AIM To investigate the clinical efficacy of gemcitabine and cisplatin-based transcatheter arterial chemoembolization (TACE) combined with radiotherapy in hilar cholangiocarcinoma.METHODS A retrospective analysis was conducted on patients clinically diagnosed with hilar cholangiocarcinoma from June 2014 to January 2017 at the Liaoning Provincial Cancer Hospital. Patients were evaluated by specialists, and those who were not suitable for surgery or unwilling to undergo surgery and met the inclusion criteria were included in the study. There were a total of 72 patients (34 males and 38 females) with an average age of 59.9 years (range, 40-72 years). According to percutaneous transhepatic biliary angiography and the patients’ wishes, stent implantation or biliary drainage tube implantation was used to relieve biliary obstruction. The patients were divided into either a control group or a combined treatment group according to their follow-up treatment. The control group consisted of a total of 35 patients who received simple biliary drainage tube placement and biliary stent implantation (7 patients with bilateral stents and 6 with a unilateral stent) and 22 patients receiving biliary drainage tube placement alone. The combined treatment group received TACE and extracorporeal radiotherapy after biliary drainage or biliary stent implantation and consisted of a total of 37 patients, including 21 patients receiving combined treatment after biliary stent placement (14 patients with bilateral stents and 7 with a unilateral stent) and 16 undergoing combined therapy after implanting the biliary drainage tube. In the combination treatment group, the TACE chemotherapy regimen employed gemcitabine and cisplatin, and the embolic agent was iodized oil. A particular dose was determined according to the patient's body surface area and the tumor staining indicated by DSA. In vitro radiotherapy was performed with intensity-modulated radiotherapy or threedimensional conformal radiotherapy at an average dose of 48.3 Gy. Both groups were followed from stent implantation or drainage tube implantation until the patient quitted or died. The median length of follow-up observation was 13 mo. The differences in overall survival time and the effect of different jaundice reducing methods (single stent, double stent, or biliary drainage) on the patency time and survival time of biliary stents were compared between the two groups;the related factors affecting overall survival time were analyzed. RESULTS The median survival time of the control group was 10.5 mo;the median survival time of patients with biliary stent implantation and those with percutaneous biliary drainage was 9.6 mo and 11.4 mo, respectively, and there was no statistically significant difference between them. The median survival time of the combined treatment group was 20.0 mo, which was significantly higher than that of the control group (P < 0.05). Among patients in the combined treatment group, the median survival time of patients who underwent biliary stent implantation and those who accepted percutaneous biliary drainage before the combination therapy was 19.5 mo and 20.1 mo, respectively, and there was no significant difference between them. In the combination treatment group, the mean time of median stent patency was 15.6 mo, which was significantly higher than that of the control group (7.0 mo;P < 0.05). The independent factors affecting survival time included age, whether to receive combination therapy, percutaneous biliary drainage tube implantation, and Bismuth-Corlette classification as type IV. CONCLUSION Gemcitabine and cisplatin-based TACE combined with radiotherapy can prolong the survival of patients with hilar cholangiocarcinoma. Independent predictors of survival include selection of combination therapy, Bismuth-Corlette classification as type IV, selection of percutaneous biliary drainage tube implantation, and age.
文摘AIM:To evaluate the efficacy of transcatheter arterial chemoembolization(TACE) using a suspension of a fine-powder formulation of cisplatin(DDPH) for hepatocellular carcinoma(HCC).METHODS:The study population was comprised of 164 patients who were treated by TACE alone.Of these patients,76 underwent TACE using a suspension of DDPH in lipiodol(LPD)(DDPH group),and the remaining 88 underwent TACE with an emulsion of doxorubicin(ADM) with LPD(ADM group).We compared the DDPH group with the ADM group in terms of the objective early response rate,progression free survival(PFS) and overall survival(OS).RESULTS:The objective early response rate in the DDPH group was significantly higher than that in the ADM group(54% vs 24%,P < 0.001).The PFS rate in the DDPH group was also significantly higher than that in the ADM group(P < 0.001).Moreover,the OS in the DDPH group was significantly longer than that in the ADM group(P = 0.002).Although the incidence rate of nausea or vomiting in the DDPH group was higher than that in the ADM group,the ADM group showed a higher incidence rate of the adverse events of hepatic arterial damage and leucopenia.No other serious complications were observed in either group.CONCLUSION:We conclude that TACE using a suspension of DDPH in LPD could be a useful treatment for HCC.
文摘Transcatheter arterial chemoembolization (TACE) has become the standard treatment for unresectable hepatocellular carcinoma (HCC). But this method has some shortages. p53 gene, which was found to be mutant in many human tumors, has been proved with broadspectrum anti-tumor effects. We reported a 23-year-old patient with recurrent HCC after irregular hepatectomy. The p53 gene was applied to this patient. We injected percutaneously and infused transcatheterally p53 gene (Gendicine, Shenzhen Sibiono Bentech, China) into his recurrent nodules in liver respectively and 4 d later, the patient received TACE therapy. In the 2 mo follow-up, the patient was in good clinical condition with normal liver function and no recurrence was identified. The case report proposed that recurrent HCC could be successfully treated with p53 gene therapy combining TACE.
文摘BACKGROUND: Transcatheter arterial chemoembolization(TACE) and TACE in combination with sorafenib(TACEsorafenib) have shown a significant survival benefit for the treatment of unresectable hepatocellular carcinoma(HCC). Adopting either as a first-line therapy carries major cost and resource implications. The objective of this study was to estimate the relative cost-effectiveness of TACE against TACE-sorafenib for unresectable HCC using a decision analytic model.METHODS: A Markov cohort model was developed to compare TACE and TACE-sorafenib. Transition probabilities and utilities were obtained from systematic literature reviews, and costs were obtained from West China Hospital, Sichuan University, China. Survival benefits were reported in quality-adjusted life-years(QALYs). The incremental cost-effectiveness ratio(ICER) was calculated. Sensitive analysis was performed by varying potentially modifiable parameters of the model.RESULTS: The base-case analysis showed that TACE cost $26 951 and yielded survival of 0.71 QALYs, and TACE-sorafenib cost $44 542 and yielded survival of 1.02 QALYs in the entire treatment. The ICER of TACE-sorafenib versus TACE was $56 745 per QALY gained, which was above threshold for cost-effectiveness in China. Sensitivity analysis revealed that the major driver of ICER was the cost post TACE-sorafenib therapy with stable state.CONCLUSION: TACE is a more cost-effective strategy than TACE-sorafenib for the treatment of unresectable HCC.

文摘Background:Recent studies showed that sequential selective transcatheter arterial chemoembolization(TACE)and portal vein embolization(PVE)provided better future liver remnant(FLR)regeneration rate and disease-free survival following surgery compared with PVE alone.The present study aimed to clarify whether preoperative sequential TACE and PVE before right hemihepatectomy can reduce postoperative hepatocellular carcinoma(HCC)recurrence and improve long-term disease-free and overall survival.Methods:Recurrence and survival outcomes were retrospectively evaluated in 205 patients with HCC who underwent right hemihepatectomy by a single surgeon from November 1993 to November 2017.Patients were divided into four groups according to the procedure performed before the surgery:sequential TACE and PVE(TACE-PVE),PVE-only,TACE-only,or na?ve control groups.The baseline patient and tumor characteristics,postoperative outcomes,recurrence-free survival and overall survival were analyzed.Results:Baseline patient and tumor characteristics upon diagnosis were similar in all four groups,while sequential TACE and PVE were well tolerated.The TACE-PVE group had a higher mean increase in percentage FLR volume compared with that of the PVE-only group(17.46%±6.63%vs.12.14%±5.93%;P=0.001).The TACE-PVE group had significantly better overall and disease-free survival rates compared with the other groups(both P<0.001).Conclusions:Sequential TACE and PVE prior to surgery can be an effective therapeutic strategy for patients with HCC scheduled for major hepatic resection.The active application of preoperative sequential TACE and PVE for HCC would allow more patients with marginal FLR volume to become candidates for major hepatic resection by promoting compensatory FLR hypertrophy without the deterioration of basal hepatic functional reserve or tumor progression.

文摘BACKGROUND: Golgi protein 73 (GP73) is a promising bio- marker of hepatocellular carcinoma (HCC). It decreases after surgical resection, and resumes upon recurrence, indicating a potential indicator for the effectiveness of the treatment. But changes of GP73 after transcatheter arterial chemoemboliza- tion (TACE) have not been reported so far. This study was to investigate the dynamic changes of GP73 in HCC patients af- ter TACE treatment, and the possible underlying mechanisms in the cell cultures. METHODS: Blood samples were collected from 72 HCC pa- tients, before TACE, at day I and day 30 after TACE. GP73 lev- els were measured by Western blotting. The dynamic changes of GP73 were analyzed and compared with image changes and clinical data. The effects of chemotherapeutic agents (5-FU and pirarubicin) on GP73 expression were tested in three HCC cell lines (HepG2, HCCLM3 and MHCC97H). RESULTS: The GP73 level was significantly elevated at day 1 and day 30 after TACE in HCC patients compared with that before the procedure (P〈0.05). There was no statistical differ- ence between the two time points after TACE, nor correlationbetween GP73 levels and dinicopathological features, tumor metastasis, and patient survival. Pirarubicin, not 5-FU, signifi- cantly increased GP73 expression in three cell lines. CONCLUSIONS: Unlike surgical resection which decreases the GP73 level, TACE significantly increased GP73 expression in patients with HCC. No correlations were observed among GP73 levels, tumor characteristics and prognosis of patients with HCC.
