Methods： A total of 121 cases of PHC by TACE after 1-2 months of surgery was retrospectively analyzed, followed up and analyzed the free survival time and the factors related to tumor-free survival. Results： In all 121 cases, 1-, 2-, and 3-year tumor-free survival rates were 72.73%, 46.21% and 26.93%, respectively. Gender, age, HBV infection, tumor size, capsule is complete, degree of differentiation and the presence of vascular thrombosis were put into the COX proportional hazards model of survival time to select the influential variables. In the clinical data of all variables entering COX proportional hazards model, tumor size, tumor differentiation and the presence of vascular thrombosis were statistically significant contributions to the model. In the tumor diameter less than or equal 10 cm [P = 0.040, Exp （B） = 2.210], vascular thrombosis [P = 0.039, Exp （B） = 2.922] and the lower degree of tumor differentiation [P = 0.035, Exp （B） = 3.038], the risk of tumor recent recurrence increased. Conclusion： Tumor size, differentiation, and the presence of vascular thrombosis are the independent risk factors affecting the prognosis of PHC after TACE.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

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Objective： The aim of the study was to analyze the tumor recurrence factors in patients of primary hepatocellular carcinoma （PHC） with postoperative transcatheter arterial chemoembolization （TACE）. Methods： A total of 121 cases of PHC by TACE after 1-2 months of surgery was retrospectively analyzed, followed up and analyzed the free survival time and the factors related to tumor-free survival. Results： In all 121 cases, 1-, 2-, and 3-year tumor-free survival rates were 72.73%, 46.21% and 26.93%, respectively. Gender, age, HBV infection, tumor size, capsule is complete, degree of differentiation and the presence of vascular thrombosis were put into the COX proportional hazards model of survival time to select the influential variables. In the clinical data of all variables entering COX proportional hazards model, tumor size, tumor differentiation and the presence of vascular thrombosis were statistically significant contributions to the model. In the tumor diameter less than or equal 10 cm [P = 0.040, Exp （B） = 2.210], vascular thrombosis [P = 0.039, Exp （B） = 2.922] and the lower degree of tumor differentiation [P = 0.035, Exp （B） = 3.038], the risk of tumor recent recurrence increased. Conclusion： Tumor size, differentiation, and the presence of vascular thrombosis are the independent risk factors affecting the prognosis of PHC after TACE.

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.
