Clinical Application of Transcatheter ArterialChemoembolization Combined with Synchronous C-armCone-Beam CT Guided Radiofrequency Ablation in treatmentof Large Hepatocellular Carcinoma

Objective: This work aimed to evaluate the safety and clinical efficacy of transcatheter arterialchemoembolization (TACE) combined with c-arm cone-beam CT guided synchronous radiofrequency ablation(RFA) in treatment of large hepatocellular carcinoma (HCC). Methods: 21 patients with large HCC were studiedfrom January 2010 to March 2012. TACE combined with synchronous C-arm cone-beam CT guided RFA wereperformed on a total of 25 lesions. Conventional imaging examination (CEUS, enhanced CT or MRI) and AFPdetection were regularly conducted to evaluate the technical success rate of combined treatment, complications,treatment response, time without disease recurrence and survival rate. Results: The technical success rate ofcombined treatment was 100%, without any significant complication. After 1 month, there were 19 cases withcomplete response and 2 cases with partial response, with an complete response rate of 90.4% (19/21) and aclinical effective rate of 100% (21/21). The complete response rates of single nodular lesions (100%, 17/17) wassignificantly higher than that of multiple nodular lesions (50%, 2/4) (P < 0. 05). During 2 to 28 months of followup,in 19 cases with complete response, the average time without disease recurrence was 10.8 ± 6 months. Thetotal survival rates of 6, 12 and 18 months in 21 patients were 100%, respectively. Conclusion: TACE combinedwith synchronous C-arm CT guided RFA is safe and effective for treatment of large HCC. The treatment efficacyfor single nodular lesion is better than that for multiple nodular lesions.     

Combination of percutaneous radiofrequency ablation with transarterial chemoembolization for hepatocellular carcinoma： observation of clinical effects

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.     

F-18] fluorodeoxyglucose positron emission tomography as a tool for early recognition of incomplete tumor destruction after radiofrequency ablation for liver metastases

BACKGROUND AND OBJECTIVES: To assess the value of FDG positron emission tomography (PET) for early detection of incomplete tumor destruction after radiofrequency ablation (RFA) for liver metastasis. METHODS: Twenty-eight unresectable liver metastases in 17 patients were treated by RFA. Patients underwent computed tomography (CT) and FDG-PET preoperatively, at 1 week, 1 month, and 3 months postoperatively. Postoperative CT and FDG-PET at 1 week and 1 month were analyzed to identify hypervascular and hypermetabolic residual tumors at the RFA site. These results were correlated with follow-up CT and, in case of reintervention, with pathologic results. RESULTS: In 24/28 of RFA-treated metastases, CT and FDG-PET at 1 week and 1 month showed no tumor residues. During follow-up, none of these 13 patients developed local recurrence at RFA site. In four patients, FDG-PET at 1 week and 1 month showed peripheral hypermetabolic residue after RFA, whereas CT did not revealed residual tumor. In three patients, local persistence of viable tumor cells was biopsy-proven at reintervention. In the fourth, follow-up CT showed subsequent development of a local recurrence. CONCLUSIONS: FDG-PET accurately monitors the local efficacy of RFA for treatment of liver metastases, as it early recognizes incomplete tumor ablation, not detectable on CT.     

经肝动脉化疗栓塞联合射频消融治疗原发性肝细胞癌合并门静脉癌栓的预后影响因素分析

背景与目的：经肝动脉化疗栓塞（transcatheter arterial chemoembolization,TACE)是否为治疗原发性肝细胞癌（hepatocellular carcinoma,HCC）合并门静脉癌栓（portal vein tumor thrombus,PVTT）的绝对禁忌,目前尚无定论。该研究旨在探讨TACE联合射频消融（radiofrequency ablation,RFA）治疗HCC合并PVTT的预后影响因素。方法：回顾性分析2011年1月1日—2013年12月31日于郑州大学附属肿瘤医院行TACE联合RFA治疗的HCC合并PVTT的157例患者的临床资料及随访数据,单因素及多因素Cox回归分析人口学资料、实验室指标及临床资料与生存时间和肿瘤转移复发情况的关系。结果：多因素Cox回归结果显示,在调整和控制其他因素后,血清白蛋白（albumin,ALB）水平为TACE联合RFA治疗后HCC合并PVTT患者3年生存及降低肿瘤复发转移风险的保护性因素,术前甲胎蛋白（alpha-fetoprotein,AFP）、丙氨酸转氨酶（alanine aminotransferase,ALT）、天门冬氨酸转氨酶（aspartate transaminase,AST）水平、门静脉癌栓部位及肝功能Child Pugh分级为患者3年生存的独立危险因素;AFP、AST水平及门静脉癌栓部位为肿瘤复发转移的独立危险因素。结论：TACE联合RFA并非治疗HCC合并PVTT的绝对禁忌,在治疗前对患者进行相关因素评估有助于更好地选择治疗方法和时机,从而提高HCC治疗水平。     

Efficacy of Transarterial Chemoembolization Combined with Radiofrequency Ablation in Treatment of Hepatocellular Carcinoma

Purpose: To evaluate efficacy of transarterial chemoembolization (TACE) combined with radiofrequencyablation (RFA) in treatment of patients with hepatocellular carcinoma. Materials and Methods: During January2009 to March 2012, 80 patients with hepatocellular carcinoma underwent TACE, with or without RFA. Alfafetoprotein(AFP) was checked before and after procedure. CT scans were obtained one month after TACE or RFAfor all patients to evaluate tumor changes. Complete response+partial response+stable disease (CR+PR+SD)/nwere used to assess the disease control rate (DCR). Survival at 3, 6 and 12 months was compared in both groups.Results: AFP levels in TACE + RFA group dropped rapidly, becoming obviously lower than that of the TACEgroup. In the TACE + RFA group DCR was 93.8%, while only 76.8% in the TACE group. The treatment effectbetween the two groups was statistically significant (P<0.05) by Ridit analysis. 1 year survival rate in the TACE+ RFA group was 92.5%, significantly higher than that of the TACE group at 77.5% (P<0.05). Conclusions:TACE and RFA as combined therapy method for patients with middle and terminal stage HCC gives full playto synergy between the two and improves the therapeutic effect.

Quality of Life after Transcatheter Arterial Chemoembolization Combined with Radiofrequency Ablation in Patients with Unresectable Hepatocellular Carcinoma Compared with Transcatheter Arterial Chemoembolization alone

Aim: The aim of this study was to assess quality of life (QoL) in patients with unresectable hepatocellular carcinoma (HCC) after transcatheter arterial chemoembolization (TACE) compared to TACE plus radiofrequency ablation (RFA) done at the same sitting, and to assess tumor therapy response after these 2 palliative interventions. Methods: 73 patients with unresectable HCC (BCLC-B) were included. Patients with tumor ≤ 5 cm were subjected to TACE (N = 45) while patients with tumors > 5 cm were subjected to TACE followed immediately by RFA (N = 28). QoL was evaluated with two validated questionnaires (EORTC QLQ-30 and EORTC HCC18). These questionnaires were filled out before intervention, 2 weeks and 2 months after intervention. Pre/post interventional changes were analyzed. The modified response evaluation criteria in solid tumor (mRECIST) were employed for the evaluation of therapeutic efficacy. Results: Baseline global health status/QoL was significantly higher in TACE group (64.1%) compared to TACE-RFA group (51.2%). Two weeks after intervention: the absolute decrease in global health state was higher in TACE-RFA (- 12.1%) compared to TACE (- 6.3%, p = 0.411). Less impairment was found in TACE group compared to TACE-RFA group for physical/social functioning, fatigue and pain but it was statistically insignificant. Two months after intervention; TACE-RFA group showed significant improvement in global health score, social and physical functioning scores, as well as significant improvement in pain and fatigue compared to TACE group. The therapeutic efficacy of TACE-RFA was better than TACE alone: complete remission, partial remission, stable disease and progressive disease were 17.9%, 32.1%, 42.9% and 7.1% Vs11.1%, 22.2%, 48.9% and 17.8%, respectively). Conclusion: Neither TACE nor TACE-RFA showed a significant decrease in QoL in patients with unresectable HCC two weeks after intervention. However, two months after intervention; TACE-RFA showed significant improvement in global health score compared to TACE monotherapy. TACE-RFA appeared safe, effective and more favorable than TACE monotherapy.
