Methods: The study period spanned from January 2021 to December 2023, and 125 patients with hepatocellular carcinoma admitted to our hospital were selected, all of whom underwent liver transplantation. They were randomly divided into an observation group (n = 63) and a control group (n = 62). The patients in the control group did not undergo TACE before the operation, and the patients in the observation group underwent TACE and quality nursing intervention before the operation. The operation time, intraoperative blood loss, length of hospitalization, liver- free period, complication rate, short-term prognosis, and liver function indexes between the two groups were compared. Results: There was no significant difference in operation time, intraoperative blood loss, and length of hospitalization between the two groups (P < 0.05). The liver-free period of patients in the observation group was longer than that of the control group (P < 0.05). The two groups had no significant difference in the incidence of biliary complications, vascular complications, and postoperative infections (P > 0.05). The rate of immune reactive complications in the observation group was lower than that of the control group (P < 0.05). There was no significant difference in the perioperative mortality rate, 1-year postoperative survival rate, and 2-year postoperative survival rate (P > 0.05). The two groups had no significant difference in postoperative liver function indexes (P > 0.05). Conclusion: Preoperative TACE and high-quality nursing intervention in patients with hepatocellular carcinoma had no adverse effect on the perioperative safety and short-term prognosis, prolonged the liver-free time, and reduced the incidence of immune-reactive complications.展开更多

This study aimed to determine how to select patients who are not suitable for TACE as the first treatment choice. Methods: A total of 243 intermediate-stage HCC patients treated with TACE at three centers were retrospectively enrolled, of which 171 were used for model training and 72 for testing. Radiomics features were screened using the Spearman correlation analysis and the least absolute shrinkage and selection operator(LASSO) algorithm. Subsequently, a radiomics model was established using extreme gradient boosting(XGBoost) with 5-fold cross-validation. The Shapley additive explanations(SHAP) method was used to visualize the radiomics model. A clinical model was constructed using univariate and multivariate logistic regression. The combined model comprising the radiomics signature and clinical factors was then established. This model’s performance was evaluated by discrimination, calibration, and clinical application. Generalization ability was evaluated by the testing cohort. Finally, the model was used to analyze overall and progression-free survival of different groups. Results: A third of the patients(81/243) were unsuitable for TACE treatment. The combined model had a high degree of accuracy as it identified TACE-unsuitable cases, at a sensitivity, specificity, and area under the receiver operating characteristic curve(AUC) of 0.759, 0.885, 0.906 [95% confidence interval(CI): 0.859-0.953] in the training cohort and 0.826, 0.776, and 0.894(95% CI: 0.815-0.972) in the testing cohort, respectively. Conclusions: The high degree of accuracy of our clinical-radiomics model makes it clinically useful in identifying intermediate-stage HCC patients who are unsuitable for TACE treatment.展开更多

文摘BACKGROUND Hepatocellular carcinoma(HCC)ranks sixth globally in cancer incidence and third in mortality rates.Unfortunately,over 70% of HCC patients forego the opportunity for curative surgery or liver transplantation due to inadequate physical examinations,poor physical condition,and limited organ availability upon diagnosis.Clinical guidelines endorse transarterial chemoembolization(TACE)as the frontline treatment for intermediate to advanced-stage HCC.Cryoablation(CRA)is an emerging local ablative therapy increasingly used in HCC management.Recent studies suggest that combining CRA with TACE offers complementary and synergistic effects,potentially improving long-term survival rates.However,the superiority of combined TACE+CRA therapy over TACE alone for HCC lesions equal to or exceeding 5 cm requires further investigation.AIM To compare the efficacy and safety of TACE combined with CRA vs TACE alone in the treatment of HCC with a diameter of≥5 cm.METHODS PubMed,EMBASE,Cochrane Library,CNKI,Wanfang,and VIP databases were searched to retrieve all relevant studies on TACE and CRA up to July 2022.Meta-analysis was performed using RevMan 5.3 software.RESULTS After screening according to the inclusion and exclusion criteria,6 articles were included,including 2 randomized controlled trials and 4 nonrandomized controlled trials,with a total of 575 patients included in the meta-analysis.The results showed that the objective response rate[odds ratio(OR)=2.56,95%confidence interval(CI):1.66-3.96,P<0.0001],disease control rate(OR=3.03,95%CI:1.88-4.89,P<0.00001),1-year survival rate(OR=3.79,95%CI:2.50-5.76,P<0.00001),2-year survival rate(OR=2.34,95%CI:1.43-3.85,P=0.0008),and 3-year survival rate(OR=3.34,95%CI:1.61-6.94,P=0.001)were all superior to those of the control group;the postoperative decrease in alpha-fetoprotein value(OR=295.53,95%CI:250.22-340.85,P<0.0001),the postoperative increase in CD4 value(OR=10.59,95%CI:8.78-12.40,P<0.00001),and the postoperative decrease in CD8 value(OR=6.47,95%CI:4.44-8.50,P<0.00001)were also significantly higher than those in the TACE-alone treatment group.CONCLUSION Compared with TACE-alone treatment,TACE+CRA combined treatment not only improves the immune function of HCC patients with a diameter of≥5 cm,but also enhances the therapeutic efficacy and long-term survival rate,without increasing the risk of complications.Therefore,TACE+CRA combined treatment may be a more recommended treatment for patients with HCC with a diameter of≥5 cm.
文摘Background:According to clinical practice guidelines,transarterial chemoembolization(TACE)is the standard treatment modality for patients with intermediate-stage hepatocellular carcinoma(HCC).Early prediction of treatment response can help patients choose a reasonable treatment plan.This study aimed to investigate the value of the radiomic-clinical model in predicting the efficacy of the first TACE treatment for HCC to prolong patient survival.Methods:A total of 164 patients with HCC who underwent the first TACE from January 2017 to September 2021 were analyzed.The tumor response was assessed by modified response evaluation criteria in solid tumors(mRECIST),and the response of the first TACE to each session and its correlation with overall survival were evaluated.The radiomic signatures associated with the treatment response were identified by the least absolute shrinkage and selection operator(LASSO),and four machine learning models were built with different types of regions of interest(ROIs)(tumor and corresponding tissues)and the model with the best performance was selected.The predictive performance was assessed with receiver operating characteristic(ROC)curves and calibration curves.Results:Of all the models,the random forest(RF)model with peritumor(+10 mm)radiomic signatures had the best performance[area under ROC curve(AUC)=0.964 in the training cohort,AUC=0.949 in the validation cohort].The RF model was used to calculate the radiomic score(Rad-score),and the optimal cutoff value(0.34)was calculated according to the Youden’s index.Patients were then divided into a high-risk group(Rad-score>0.34)and a low-risk group(Rad-score≤0.34),and a nomogram model was successfully established to predict treatment response.The predicted treatment response also allowed for significant discrimination of Kaplan-Meier curves.Multivariate Cox regression identified six independent prognostic factors for overall survival,including male[hazard ratio(HR)=0.500,95%confidence interval(CI):0.260–0.962,P=0.038],alpha-fetoprotein(HR=1.003,95%CI:1.002–1.004,P<0.001),alanine aminotransferase(HR=1.003,95%CI:1.001–1.005,P=0.025),performance status(HR=2.400,95%CI:1.200–4.800,P=0.013),the number of TACE sessions(HR=0.870,95%CI:0.780–0.970,P=0.012)and Rad-score(HR=3.480,95%CI:1.416–8.552,P=0.007).Conclusions:The radiomic signatures and clinical factors can be well-used to predict the response of HCC patients to the first TACE and may help identify the patients most likely to benefit from TACE.

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 While gelatin sponge particles and calibrated microspheres are commonly used as embolic materials in conventional transarterial chemoembolization(cTACE),direct comparisons between these embolic agents are rare.AIM To compare the efficacy and safety of superselective cTACE using Embosphere®or Marine gel®in patients with early-stage hepatocellular carcinoma(HCC).METHODS This retrospective study included 70 patients with small(<4 cm)HCC who underwent cTACE with Embosphere®(n=33)or Marine gel®(n=37)as the embolic agent at a single center between March 2021 and July 2022.The radiologic images and clinical data were retrospectively reviewed,with an emphasis on tumor response,procedure-related complications,and local tumor recurrence.The primary index tumor was assessed on a 1-mo follow-up image,and local progression-free survival was obtained using the Kaplan-Meier method and was compared by the log-rank test.RESULTS The median tumor size of both groups was 1.5 cm,and 69 patients achieved a complete response one month after cTACE.The cumulative local recurrence rate at 12 mo was 15.5%in the Embosphere®group and 14.4%in the Marine gel®group.The local progression-free survival was not significantly different between the two groups(P=0.83).In the multivariate analysis,high serum alphafetoprotein was the only significant poor prognostic factor for local tumor progression(P=0.01).Postembolization syndrome occurred in 36.4%of the Embosphere®group and 35.1%of the Marine gel®group,and there were no cases of biloma,biliary duct dilation,or liver abscess in either group.CONCLUSION Calibrated gelatin sponge particles(Marine gel®)and calibrated microspheres(Embosphere®)have similar outcomes in terms of tumor response for superselective cTACE of small HCC.

文摘BACKGROUND Although the past decade has seen remarkable advances in treatment options for hepatocellular carcinoma(HCC),the dismal overall prognosis still envelops HCC patients.Several comparative trials have been conducted to study whether transarterial chemoembolization(TACE)could improve clinical outcomes in patients receiving sorafenib for advanced HCC;however,the findings have been inconsistent.AIM To study the potential synergies and safety of sorafenib plus TACE vs sorafenib alone for treating advanced HCC,by performing a systematic review and metaanalysis.METHODS This study was conducted following the PRISMA statement.A systematic literature search was conducted using the Cochrane Library,Embase,PubMed,and Web of Science databases.Data included in the present work were collected from patients diagnosed with advanced HCC receiving sorafenib plus TACE or sorafenib alone.Data synthesis and meta-analysis were conducted using Review Manager software.RESULTS The present study included 2780 patients from five comparative clinical trials(1 was randomized control trial and 4 were retrospective studies).It was found that patients receiving sorafenib plus TACE had better prognoses in terms of overall survival(OS),with a combined hazard ratio(HR)of 0.65[95%confidence interval(95%CI):0.46–0.93,P=0.02,n=2780].Consistently,progression free survival(PFS)and time to progression(TTP)differed significantly between the sorafenib plus TACE arm and sorafenib arm(PFS:HR=0.62,95%CI:0.40–0.96,P=0.03,n=443;TTP:HR=0.73,95%CI:0.64-0.83,P<0.00001,n=2451).Disease control rate(DCR)was also significantly increased by combination therapy(risk ratio=1.36,95%CI:1.02-1.81,P=0.04,n=641).Regarding safety,the incidence of any adverse event(AE)was increased due to the addition of TACE;however,no significant difference was found in grade≥3 AEs.CONCLUSION The combination of sorafenib with TACE has superior efficacy to sorafenib monotherapy,as evidenced by prolonged OS,PFS,and TTP,as well as increased DCR.Additional high-quality trials are essential to further validate the clinical benefit of this combination in the treatment of advanced HCC.
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 The objectives of this study were to assess the safety and efficacy of drug-eluting bead transarterial chemoembolization(DEB-TACE)as neoadjuvant therapy before liver transplantation(LT)for advanced-stage hepatocellular carcinoma(HCC)and to analyze the prognostic factors.AIM To determine whether DEB-TACE before LT is superior to LT for advanced-stage HCC.METHODS A total of 99 individuals diagnosed with advanced HCC were studied retrospectively.The participants were categorized into the following two groups based on whether they had received DEB-TACE before LT:DEB-TACE group(n=45)and control group(n=54).The participants were further divided into two subgroups based on the presence or absence of segmental portal vein tumor thrombus(PVTT).The DEB-TACE group consisted of two subgroups:Group A(n=31)without PVTT and group B(n=14)with PVTT.The control group also had two subgroups:Group C(n=37)without PVTT and group D(n=17)with PVTT.Data on patient demographics,disease characteristics,therapy response,and adverse events(AEs)were collected.The overall survival(OS)and recurrence-free survival(RFS)rates were assessed using Kaplan-Meier curves.Univariate and multivariate Cox regression analyses were conducted to determine the parameters that were independently related to OS and RFS.RESULTS The DEB-TACE group exhibited an overall response rate of 86.6%.Following therapy,there was a significant decrease in the median alpha-fetoprotein(AFP)level(275.1 ng/mL vs 41.7 ng/mL,P<0.001).The main AE was post-embolization syndrome.The 2-year rates of RFS and OS were significantly higher in the DEB-TACE group than in the control group(68.9%vs 38.9%,P=0.003;86.7%vs 63.0%,P=0.008).Within the subgroups,group A had higher 2-year rates of RFS and OS compared to group C(71.0%vs 45.9%,P=0.038;83.8%vs 62.2%,P=0.047).The 2-year RFS rate of group B was markedly superior to that of group D(64.3%vs 23.5%,P=0.002).Results from multivariate analyses showed that pre-LT DEB-TACE[hazard ratio(HR)=2.73,95%confidence interval(CI):1.44-5.14,P=0.04],overall target tumor diameter≤7 cm(HR=1.98,95%CI:1.05-3.75,P=0.035),and AFP level≤400 ng/mL(HR=2.34;95%CI:1.30-4.19,P=0.009)were significant risk factors for RFS.Additionally,pre-LT DEBTACE(HR=3.15,95%CI:1.43-6.96,P=0.004)was identified as a significant risk factor for OS.CONCLUSION DEB-TACE is a safe and efficient therapy for advanced-stage HCC and also enhances patient survival after LT.
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BACKGROUND The efficacy and safety of transarterial chemoembolization(TACE)combined with lenvatinib plus programmed cell death protein-1(PD-1)for unresectable hepato-cellular carcinoma(HCC)have rarely been evaluated and it is unknown which factors are related to efficacy.AIM To evaluate the efficacy and independent predictive factors of TACE combined with lenvatinib plus PD-1 inhibitors for unresectable HCC.METHODS This study retrospectively enrolled patients with unresectable HCC who received TACE/lenvatinib/PD-1 treatment between March 2019 and April 2022.Overall survival(OS)and progression-free survival(PFS)were determined.The objective response rate(ORR)and disease control rate(DCR)were evaluated in accordance with the modified Response Evaluation Criteria in Solid Tumors.Additionally,the prognostic factors affecting the clinical outcome were assessed.RESULTS One hundred and two patients were enrolled with a median follow-up duration of 12.63 months.The median OS was 26.43 months(95%CI:17.00-35.87),and the median PFS was 10.07 months(95%CI:8.50-11.65).The ORR and DCR were 61.76%and 81.37%,respectively.The patients with Barcelona Clinic Liver Cancer Classification(BCLC)B stage,early neutrophil-to-lymphocyte ratio(NLR)response(decrease),or early alpha-fetoprotein(AFP)response(decrease>20%)had superior OS and PFS than their counterparts.CONCLUSION This study showed that TACE/lenvatinib/PD-1 treatment was well tolerated with encouraging efficacy in patients with unresectable HCC.The patients with BCLC B-stage disease with early NLR response(decrease)and early AFP response(decrease>20%)may achieve better clinical outcomes with this triple therapy.
文摘BACKGROUND This study was designed to investigate the clinical efficacy and safety of Gamma Knife®combined with transarterial chemoembolization(TACE)and immunotherapy in the treatment of primary liver cancer.AIM To investigate the clinical efficacy and safety of Gamma Knife®combined with TACE and immune-targeted therapy in the treatment of primary liver cancer.METHODS Clinical data from 51 patients with primary liver cancer admitted to our hospital between May 2018 and October 2022 were retrospectively collected.All patients underwent Gamma Knife®treatment combined with TACE and immunotherapy.The clinical efficacy,changes in liver function,overall survival(OS),and progression-free survival(PFS)of patients with different treatment responses were evaluated,and adverse reactions were recorded.RESULTS The last follow-up for this study was conducted on October 31,2023.Clinical evaluation of the 51 patients with primary liver cancer revealed a partial response(PR)in 27 patients,accounting for 52.94%(27/51);stable disease(SD)in 16 patients,accounting for 31.37%(16/51);and progressive disease(PD)in 8 patients,accounting for 15.69%(8/51).The objective response rate was 52.94%,and the disease control rate was 84.31%.Alanine aminotransferase,aspartate aminotransferase,lactate dehydrogenase,and alpha-fetoprotein isoform levels decreased after treatment compared with pretreatment(all P=0.000).The median OS was 26 months[95%confidence interval(95%CI):19.946-32.054]in the PR group and 19 months(95%CI:14.156-23.125)in the SD+PD group,with a statistically significant difference(P=0.015).The median PFS was 20 months(95%CI:18.441-34.559)in the PR group and 12 months(95%CI:8.745-13.425)in the SD+PD group,with a statistically significant difference(P=0.002).Common adverse reactions during treatment included nausea and vomiting(39.22%),thrombocytopenia(27.45%),and leukopenia(25.49%),with no treatment-related deaths reported.CONCLUSION Gamma Knife®combined with TACE and immune-targeted therapy is safe and effective in the treatment of primary liver cancer and has a good effect on improving the clinical benefit rate and liver function of patients.
文摘BACKGROUND Transarterial chemoembolization(TACE)combined with microwave ablation(MWA)is an effective treatment strategy for patients with advanced gastric cancer and liver metastasis.However,it may cause severe postoperative pain and inflammatory responses.The paravertebral block(PVB)is a regional anesthetic technique that provides analgesia to the thoracic and abdominal regions.AIM To evaluate the effect of PVB on postoperative analgesia and inflammatory response in patients undergoing TACE combined with MWA for advanced gastric cancer and liver metastasis.METHODS Sixty patients were randomly divided into PVB and control groups.The PVB group received ultrasound-guided PVB with 0.375%ropivacaine preoperatively,whereas the control group received intravenous analgesia with sufentanil.The primary outcome was the visual analog scale(VAS)score for pain at 6 h,12 h,24 h,and 48 h after the procedure.Secondary outcomes were the dose of sufentanil used,incidence of adverse events,and levels of inflammatory markers(white blood cell count,neutrophil percentage,C-reactive protein,and procalcitonin)before and after the procedure.RESULTS The PVB group had significantly lower VAS scores at 6 h,12 h,24 h,and 48 h after the procedure compared with the control group(P<0.05).The PVB group also had a significantly lower consumption of sufentanil and a lower incidence of nausea,vomiting,and respiratory depression than did the control group(P<0.05).Compared with the control group,the PVB group had significantly lower levels of inflammatory markers 24 h and 48 h after the procedure(P<0.05).CONCLUSION PVB can effectively reduce postoperative pain and inflammatory responses and improve postoperative comfort and recovery in patients with advanced gastric cancer and liver metastasis treated with TACE combined with MWA.
文摘BACKGROUND Portal vein tumor thrombus is an important indicator of poor prognosis in patients with hepatocellular carcinoma.Transarterial chemoembolization is recommended as the standard first-line therapy for unresectable hepatocellular carcinoma.Portal vein stent placement is a safe and effective therapy for promptly restoring flow and relieving portal hypertension caused by tumor thrombus.AIM To assess the clinical significance of transarterial chemoembolization plus stent placement for the treatment of hepatocellular carcinoma with main portal vein tumor thrombosis.METHODS We searched English and Chinese databases,assessed the quality of the included studies,analyzed the characteristic data,tested heterogeneity,explored heterogeneity,and tested publication bias.RESULTS In total,eight clinical controlled trials were included.The results showed that the pressure in the main portal vein after stent placement was significantly lower than that with no stent placement.The cumulative stent patency and survival rates at 6 and 12 months were lower in the transarterial chemoembolization+stent placement group than in the transarterial chemoembolization+stent placement+brachytherapy/radiotherapy group.The survival rates of patients treated with transarterial chemoembolization+stent placement for 6 and 12 months were higher than those of patients treated with transarterial chemoembolization alone.CONCLUSION For Chinese patients with hepatocellular carcinoma with main portal vein tumor thrombosis,transarterial chemoembolization plus stenting is effective.Transarterial chemoembolization+stent placement is more effective than transarterial chemoembolization alone.Transarterial chemoembolization+stent placement+brachytherapy/radiotherapy is more effective than transarterial chemoembolization+stenting.
文摘BACKGROUND The recurrence rate of liver cancer after surgery is high.Radiofrequency ablation(RFA)combined with transcatheter arterial chemoembolization(TACE)is an effective treatment for liver cancer;however,its efficacy in recurrent liver cancer remains unclear.AIM To investigate the clinical effect of TACE combined with RFA in the treatment of recurrent liver cancer.METHODS Ninety patients with recurrent liver cancer were divided into 2 groups according to treatment plan:Control(RFA alone);and experimental[TACE combined with RFA(TACE+RFA)].The incidence of increased alanine aminotransferase levels,complications,and other indices were compared between the two groups before and after the procedures.RESULTS One month after the procedures,the short-term efficacy rate and Karnofsky Performance Status scores of the experimental group were significantly higher than those of the control group(P<0.05).Alpha-fetoprotein(AFP)and total bilirubin levels were lower than those in the control group(P<0.05);The overall response rate was 82.22%and 66.67%in the experimental and control groups,respectively;The disease control rate was 93.33%and 82.22%in the experimental and control groups,respectively,the differences are statistically significant(P<0.05).And there were no statistical differences in complications between the two groups(P>0.05).CONCLUSION TACE+RFA was effective for the treatment of recurrent liver cancer and significantly reduced AFP levels and improved various indices of liver function.
文摘This article reviews the concept and clinical manifestations of post embolism syndrome after transarterial chemoembolization(TACE),and the prevention or timely intervention of post embolism syndrome in advance is expected to reduce its incidence and degree in clinical treatment,and to improve the quality of treatment of Hepatocellular Carcinoma Carcinoma(HCC).
文摘Objective: To investigate the effects of preoperative hepatic artery chemoembolization (TACE) and quality nursing interventions on the perioperative safety and short-term prognosis in patients with hepatocellular carcinoma undergoing liver transplantation. Methods: The study period spanned from January 2021 to December 2023, and 125 patients with hepatocellular carcinoma admitted to our hospital were selected, all of whom underwent liver transplantation. They were randomly divided into an observation group (n = 63) and a control group (n = 62). The patients in the control group did not undergo TACE before the operation, and the patients in the observation group underwent TACE and quality nursing intervention before the operation. The operation time, intraoperative blood loss, length of hospitalization, liver- free period, complication rate, short-term prognosis, and liver function indexes between the two groups were compared. Results: There was no significant difference in operation time, intraoperative blood loss, and length of hospitalization between the two groups (P < 0.05). The liver-free period of patients in the observation group was longer than that of the control group (P < 0.05). The two groups had no significant difference in the incidence of biliary complications, vascular complications, and postoperative infections (P > 0.05). The rate of immune reactive complications in the observation group was lower than that of the control group (P < 0.05). There was no significant difference in the perioperative mortality rate, 1-year postoperative survival rate, and 2-year postoperative survival rate (P > 0.05). The two groups had no significant difference in postoperative liver function indexes (P > 0.05). Conclusion: Preoperative TACE and high-quality nursing intervention in patients with hepatocellular carcinoma had no adverse effect on the perioperative safety and short-term prognosis, prolonged the liver-free time, and reduced the incidence of immune-reactive complications.

文摘BACKGROUND Conventional transarterial chemoembolization(cTACE)is the current standard treatment for intermediate-stage hepatocellular carcinoma(HCC).Postembolization syndrome(PES)is complex clinical syndrome that presents as fever,abdominal pain,nausea,and vomiting.Either dexamethasone(DEXA)or Nacetylcysteine(NAC)is used to prevent PES;however,the synergistic effect of their combined therapy for preventing PES and liver decompensation has not been determined.AIM To evaluate the efficacy of DEXA and NAC combination in preventing PES and liver decompensation after cTACE.METHODS Patients with Barcelona Clinic Liver Cancer stage A or B HCC who were scheduled for TACE were prospectively enrolled.All patients were randomly stratified to receive NAC and DEXA or placebo.The dual therapy(NAC+DEXA)group received intravenous administration of 10 mg DEXA every 12 h,NAC 24 h prior to cTACE(150 mg/kg/h for 1 h followed by 12.5 mg/kg/h for 4 h),and a continuous infusion of 6.25 mg/h NAC plus 4 mg DEXA every 12 h for 48 h after cTACE.The placebo group received an infusion of 5%glucose solution until 48 h after procedure.PES was defined by South West Oncology Group toxicity code grading of more than 2 that was calculated using incidence of fever,nausea,vomiting,and pain.RESULTS One-hundred patients were enrolled with 50 patients in each group.Incidence of PES was significantly lower in the NAC+DEXA group compared with in the placebo group(6%vs 80%;P<0.001).Multivariate analysis showed that the dual treatment is a protective strategic therapy against PES development[odds ratio(OR)=0.04;95%confidence interval(CI):0.01-0.20;P<0.001).Seven(14%)patients in the placebo group,but none in the NAC+DEXA group,developed post-TACE liver decompensation.A dynamic change in Albumin-Bilirubin score of more than 0.5 point was found to be a risk factor for post-TACE liver decompensation(OR=42.77;95%CI:1.01-1810;P=0.049).CONCLUSION Intravenous NAC+DEXA administration ameliorated the occurrence of PES event after cTACE in patients with intermediate-stage HCC.

文摘Background: Although transarterial chemoembolization(TACE) is the first-line therapy for intermediatestage hepatocellular carcinoma(HCC), it is not suitable for all patients. This study aimed to determine how to select patients who are not suitable for TACE as the first treatment choice. Methods: A total of 243 intermediate-stage HCC patients treated with TACE at three centers were retrospectively enrolled, of which 171 were used for model training and 72 for testing. Radiomics features were screened using the Spearman correlation analysis and the least absolute shrinkage and selection operator(LASSO) algorithm. Subsequently, a radiomics model was established using extreme gradient boosting(XGBoost) with 5-fold cross-validation. The Shapley additive explanations(SHAP) method was used to visualize the radiomics model. A clinical model was constructed using univariate and multivariate logistic regression. The combined model comprising the radiomics signature and clinical factors was then established. This model’s performance was evaluated by discrimination, calibration, and clinical application. Generalization ability was evaluated by the testing cohort. Finally, the model was used to analyze overall and progression-free survival of different groups. Results: A third of the patients(81/243) were unsuitable for TACE treatment. The combined model had a high degree of accuracy as it identified TACE-unsuitable cases, at a sensitivity, specificity, and area under the receiver operating characteristic curve(AUC) of 0.759, 0.885, 0.906 [95% confidence interval(CI): 0.859-0.953] in the training cohort and 0.826, 0.776, and 0.894(95% CI: 0.815-0.972) in the testing cohort, respectively. Conclusions: The high degree of accuracy of our clinical-radiomics model makes it clinically useful in identifying intermediate-stage HCC patients who are unsuitable for TACE treatment.

文摘Background:There is currently no standard adjuvant treatment proven to prevent hepatocellular carcinoma(HCC)recurrence.Recent studies suggest that postoperative adjuvant transarterial chemoembolization(PA-TACE)is beneficial for patients at high risk of tumor recurrence.However,it is difficult to select the patients.The present study aimed to develop an easy-to-use score to identify these patients.Methods:A total of 4530 patients undergoing liver resection were recruited.Independent risk factors were identified by Cox regression model in the training cohort and the Primary liver cancer big data transarterial chemoembolization(PDTE)scoring system was established.Results:The scoring system was composed of ten risk factors including alpha-fetoprotein(AFP),albuminbilirubin(ALBI)grade,operative bleeding loss,resection margin,tumor capsular,satellite nodules,tumor size and number,and microvascular and macrovascular invasion.Using 5 points as risk stratification,the patients with PA-TACE had higher recurrence-free survival(RFS)compared with non-TACE in>5 points group(P<0.001),whereas PA-TACE patients had lower RFS compared with non-TACE in≤5 points group(P=0.013).In the training and validation cohorts,the C-indexes of PDTE scoring system were 0.714[standard errors(SE)=0.010]and 0.716(SE=0.018),respectively.Conclusions:The model is a simple tool to identify PA-TACE for HCC patients after liver resection with a favorable performance.Patients with>5 points may benefit from PA-TACE.

文摘Background:Due to the high heterogeneity among hepatocellular carcinoma(HCC)patients receiving transarterial chemoembolization(TACE),the prognosis of patients varies significantly.The decisionmaking on the initiation and/or repetition of TACE under different liver functions is a matter of concern in clinical practice.Thus,we aimed to develop a prediction model for TACE candidates using risk stratification based on varied liver function.Methods:A total of 222 unresectable HCC patients who underwent TACE as their only treatment were included in this study.Cox proportional hazards regression was performed to select the independent risk factors and establish a predictive model for the overall survival(OS).The model was validated in patients with different Child-Pugh class and compared to previous TACE scoring systems.Results:The five independent risk factors,including alpha-fetoprotein(AFP)level,maximal tumor size,the increase of albumin-bilirubin(ALBI)grade score,tumor response,and the increase of aspartate aminotransferase(AST),were used to build a prognostic model(ASARA).In the training and validation cohorts,the OS of patients with ASARA score≤2 was significantly higher than that of patients with ASARA score>2(P<0.001,P=0.006,respectively).The ASARA model and its modified version“AS(ARA)”can effectively distinguish the OS(P<0.001,P=0.004)between patients with Child-Pugh class A and B,and the C-index was 0.687 and 0.706,respectively.For repeated TACE,the ASARA model was superior to Assessment for Retreatment with TACE(ART)and ALBI grade,maximal tumor size,AFP,and tumor response(ASAR)among Child-Pugh class A patients.For the first TACE,the performance of AS(ARA)was better than that of modified hepatoma arterial-embolization prognostic(mHAP),mHAP3,and ASA(R)models among Child-Pugh class B patients.Conclusions:The ASARA scoring system is valuable in the decision-making of TACE repetition for HCC patients,especially Child-Pugh class A patients.The modified AS(ARA)can be used to screen the ideal candidate for TACE initiation in Child-Pugh class B patients with poor liver function.
