Objective： To observe the clinical effect of radiofrequency ablation （RFA） combined with transcatheter arterial chemoembolization （TACE） for advanced hepatocellnlar carcinoma （HCC）. Methods： A total of 92 eases of advanced primary liver cancer underwent TACE and RFA treatment from June 2005 to 2011 at the Department of Hepatobiliary Surgery, the First Affiliated Hospital of Bengbu Medical College. A total of 88 cases with complete clinical treatment and follow-up data were divided into two groups： 43 patients treated with TACE （TACE group） and 45 patients that received TACE combined with RFA treatment （TACE ＋ RFA group）. After clinical data assessment, tumor size and survival status were not significantly different between the groups as determined by stratified analysis. Results： Before and after surgery, spiral CT radiography and color comparison observed ablation conditions. The tumor necrosis rates after treatment （CR ＋ PR） were 67.4% （29/43） and 91.1% （41/45） for the TACE and combined treatment groups, respectively, and the difference was statistically significant （P〈0.05）. The quality of life was significantly improved for patients undergoing TACE ~ RFA compared with the control group. Survival duration was not significantly different in patients undergoing TACE ~ RFA compared with the control group. Conclusions： In this study, the effect of RFA combined with TACE treatment was better than TACE alone in treating advanced HCC.

Radiofrequency ablation or microwave ablation combined with transcatheter arterial chemoembolization in treatment of hepatocellular carcinoma by comparing with radiofrequency ablation alone

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.

A comparative study between Embosphere~ and conventional transcatheter arterial chemoembolization for treatment of unresectable liver metastasis from GIST

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.

Safety and efficacy of hepatic arterial infusion chemotherapy with raltitrexed and oxaliplatin post-transarterial chemoembolization for unresectable hepatocellular carcinoma

Objective:To investigate the safety,efficacy,and prognostic factors of hepatic arterial infusion chemotherapy(HAIC)with raltitrexed and oxaliplatin post-transarterial chemoembolization(TACE)for unresectable hepatocellular carcinoma(uHCC).Methods:Thirty-seven patients with uHCC who received HAIC with raltitrexed and oxaliplatin post-TACE between June 2014 and December 2016 at our hospital were recruited.The primary endpoint was overall survival(OS),and secondary endpoint was progression-free survival(PFS).The overall response rate(ORR)was evaluated using the modified Response Evaluation Criteria in Solid Tumors.Toxicity was assessed according to the Common Terminology Criteria for Adverse Events(v4.0).The OS and prognostic factors were analyzed using the Kaplan-Meier method,log-rank test,and Cox regression models.Results:Three(8.1%)patients achieved complete response,17(46.0%)patients achieved partial response,and the ORR was54.0%.The median OS and median PFS were 19.0 months and 12.0 months,respectively.The common toxicities included grade 3-4 increased aspartate aminotransferase levels(8/37,21.6%),grade 1-2 hyperbilirubinemia(75.7%,28/37),nonspecific abdominal pain and fever,and grade 2-3 thrombocytopenia(18.9%,7/37);no patients developed grade 3-4 neutropenia.Univariate analysis showed that the tumor diameter(≤50 mm,p=0.028),Barcelona Clinic Liver Cancer(BCLC)stage(p=0.012),hepatitis B virus DNA level(p=0.033),and derived neutrophil-to-lymphocyte ratio(dNLR;derived neutrophils/leukocytes minus neutrophils)(p=0.003)were predictive factors for prognosis.Multivariate analysis showed that patients with BCLC stage B disease(p=0.029)and dNLR<2 before therapy(p=0.004)had better prognosis.Conclusions:HAIC with raltitrexed and oxaliplatin post-TACE is a safe and efficacious therapy for patients with uHCC;in particular,those with BCLC stage B and dNLR<2 have better prognosis.

Sequential transcatheter arterial chemoembolization,three-dimensional conformal radiotherapy,and high-intensity focused ultrasound treatment for unresectable hepatocellular carcinoma patients

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.

Cost-effectiveness analysis of transcatheter arterial chemoembolization with or without sorafenib for the treatment of unresectable hepatocellular carcinoma

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.

Novel imaging biomarkers of response to transcatheter arterial chemoembolization in hepatocellular carcinoma patients

Hepatocellular carcinoma common cause of cancer death （HCC） is the third most worldwide （1）. Most patients present with intermediate or advanced disease that is not amenable to curative treatment, and the median survival in this group is 6-8 months （2）. Several studies and well- designed randomized trials have shown a positive effect of transcatheter arterial chemoembolization （TACE） on patient outcome and survival （3-8）. As nicely described in the present article from Wring et al., assessment of tumor response is of extreme importance in patients undergoing locoregional treatments of liver cancer （9）. Early assessment of the effectiveness of TACE and monitoring of tumor response are paramount to the identification of treatment failure, guidance of future therapy, and determination of the interval for repeat treatment.

Efficacy of transcatheter arterial chemoembolization combined with sorafenib in inhibiting tumor angiogenesis in a rabbit VX2 liver cancer model

Background:The aim of this study was to investigate the effects of transcatheter arterial chemoembolization(TACE)combined with sorafenib on tumor angiogenesis.Materials and methods:Thirty New Zealand rabbit VX2 liver cancer model animals were divided into five groups,which received either normal saline(A),TACE(B),sorafenib(C),sorafenib followed by TACE(D),or TACE followed by sorafenib(E).Serum vascular endothelial growth factor(VEGF)levels were measured before and after TACE via ELISA.Immunohistochemistry for CD34 was performed to evaluate microvessel density(MVD),and ultrasonography was used to access tumor volume.Results:VEGF levels declined in group C but increased significantly on the 3 rd post-operative day in groups B,D,and E.Levels decreased after the 7 th post-operative day.Peak levels were significantly lower in group D than in groups B and E.On the 14 th post-operative day,VEGF levels were the lowest in group C,followed by those in groups D and B.MVD was the lowest in group C followed by that in group D and E,and was the highest in group B.Group D had the smallest tumor volume.HE staining of tumor tissues from group C showed apoptosis in a scattered patchy pattern,whereas in groups B,D,and E,large areas of tumor cell necrosis were visible.Conclusion:TACE can up-regulate serum VEGF levels,which in turn accelerates the formation of new blood vessels.Thus,TACE combined with sorafenib inhibits VEGF and angiogenesis,and pre-operative administration of sorafenib has a more superior anti-angiogenic effect than post-operative administration.

Evaluation of the safety and efficacy of glucocorticoid therapy for hyperbilirubinemia in patients with hepatocellular carcinoma who have undergone transcatheter arterial chemoembolization

Objective The aim of this study was to analyze the safety and efficacy of glucocorticoid treatment for hyperbilirubinemia in patients with hepatocellular carcinoma(HCC)who have undergone transcatheter arterial chemoembolization(TACE).Methods We conducted a retrospective analysis of the clinical data of 198 patients with HCC who were admitted to The Fifth Medical Center of PLA General Hospital from June 2014 to August 2019 and underwent TACE therapy.The patients were divided into glucocorticoid(GCC)treatment group and control group.Standard liver-protecting procedures were used in both groups.The treatment group also received intravenous injections of methylprednisolone sodium succinate for 3–5 days.Reduction in bilirubin concentration,mean duration of hospitalization,and complications were compared between the two groups to investigate the safety and efficacy of GCCs for treatment of hyperbilirubinemia after TACE treatment.Results Bilirubin concentrations were significantly lower in the treatment group than in control group on days 3 and 5 after GCC/conventional liver-protecting treatment(P<0.05).The treatment group had significantly shorter durations of total post-surgery hospitalization,and recovery time than the control group(14.5±4.6 days vs.17.5±6.6 days,P<0.001;9.2±3.3 days vs.11.8±5.4 days,P=0.001;7.0±3.3 days vs.9.3±4.6 days,P<0.001).No GCC-associated complications were detected in the treatment group.Conclusion Short-term use of GCCs to treat hyperbilirubinemia in patients with HCC who have undergone TACE is safe and associated with rapid decline in bilirubin concentration and shorter hospital stay compared with patients who did not receive GCCs.

Changes in the frequency of myeloid-derived suppressor cells after transarterial chemoembolization with gelatin sponge microparticles for hepatocellular carcinoma

Purpose: A series of clinical studies have established the safety and efficacy of transcatheter arterial chemoembolization(TACE) with gelatin sponge microparticles(GSMs) in treating hepatocellular carcinoma(HCC). HCC can lead to obvious necrosis inside tumors, especially larger ones, although it is unclear whether such necrotic tumor tissue can induce favorable immune reactions against the tumor. Myeloid-derived suppressor cells(MDSCs)have immunosuppressive functions and are currently considered a very important cell type affecting tumor immunity. This study observed changes in MDSC frequency in peripheral blood before and after GSM–TACE to evaluate the effect on the immune function of HCC patients.Methods: Eight patients diagnosed with HCC underwent GSM–TACE treatment in the Hepatobiliary Interventional Department of Beijing Tsinghua Chang Gung Hospital, Beijing, China;we followed up with the patients over a period of 30 days post-surgery. We used flow cytometry(FCM) to quantify the frequency of MDSCs in peripheral blood before TACE, 10 days after surgery and 30 days after surgery.Results: MDSC frequency after GSM–TACE had a significant downward trend. Pre-TACE, it was 30.73% ? 11.93%,decreasing to 18.60% ? 11.37% at 10 days after operation. This decrease was not statistically significant(P > 0.05). MDSC frequency was even lower 30 days after TACE(7.63% ? 7.32%) than at 10 days after TACE(P < 0.05), and there was a significant difference compared with pre-TACE(P < 0.001). We evaluated tumor response at 30 days after GSM–TACE according to the Modified Response Evaluation Criteria in Solid Tumors(mRECIST), and all eight patients showed partial response(PR).Conclusion: Our results confirmed that GSM–TACE was beneficial for improving anti-tumor immunity in the treatment of HCC.

目的随机分组对照探讨经动脉化疗栓塞(transcatheter arterial chemoembolization,TACE)及门脉内植入支架联合或未联合血管内植入碘-125(125Ⅰ)粒子条治疗原发性肝癌(hepatocellular carcinoma,HCC)伴门脉主干癌栓(main portal vein tumor thrombus,MPVTT)的临床疗效。方法选择2009年2月至2011年4月于我院接受肝癌TACE治疗的60例HCC合并MPVTT患者(男52例,女8例,平均年龄53岁)进行随机分组。A组在门脉内植入支架及125Ⅰ粒子条,B组仅在门脉内植入支架,每组30例。分别对两组患者进行生存期、支架通畅率及相关不良事件的分析。结果门脉内植入支架及125Ⅰ粒子条介入技术成功率为100%,无严重手术并发症及相关不良事件发生。A组和B组患者的中位生存期分别为335天及142天(P=0.002,HR=2.683)。A组和B组患者支架的中位通畅期分别为340天及190天(P=0.038,HR=2.252)。结论门脉支架及TACE联合血管内植入125I粒子条能明显延长HCC伴MPVTT患者的支架通畅期、生存期,提高患者生存质量,是临床治疗HCC合并MPVTT的重大突破。

伽玛刀序贯TACE治疗肝癌伴门静脉癌栓的临床观察

目的探讨伽玛刀和经皮肝动脉化疗栓塞（TACE）序贯治疗原发性肝癌伴门静脉癌栓的临床疗效和不良反应。方法将2004年2月至2008年3月收治的101例原发性肝癌伴门脉癌栓患者随机分为3组,A组34例,先给予伽玛刀治疗,之后予TACE治疗;B组37例,先给予TACE治疗,之后予伽玛刀治疗;C组30例,单纯行伽玛刀治疗。结果 101例患者治疗3个月的有效率为87.1%（88/101）。A、B两组之间的有效率、中位生存期、局部控制率、生存率、门脉癌栓有效率、AFP改善率及腹胀、腹部不适改善率比较,差异均无统计学意义（P〉0.05）,但均优于C组（P〈0.05）。B组肝功能恶化率高于A组（P〈0.05）,而A组和C组比较差异无统计学意义（P〉0.05）。全组患者随访5~36个月,未见严重并发症。结论对伴门静脉癌栓的原发性肝癌采用伽玛刀联合TACE治疗的疗效较好,先给予伽玛刀治疗再行TACE对肝功能影响较小。
