Efficacy of combination therapy with transcatheter arterial chemoembolization and radiofrequency ablation for intermediate-stage hepatocellular carcinoma

Abstract

Objectives: Transcatheter arterial chemoembolization (TACE) is the standard therapy for patients with intermediate-stage hepatocellular carcinoma (HCC). This study aimed to determine whether combination therapy with radiofrequency ablation (RFA) and TACE was superior to TACE monotherapy for intermediate-stage HCC and identify cases in which this technique was the most effective.

Materials and methods: We selected patients with intermediate HCC who met the following eligibility criteria: (1) ≥ 20 years of age, (2) receiving initial therapy, (3) ≤7 tumors, and (4) maximum tumor diameter <5?cm. We performed propensity score matching (PSM) using potential confounding factors. We retrospectively compared the cumulative overall survival rate and recurrence-free survival rate between the TACE?+?RFA and TACE groups. Additionally, a sub-group analysis was performed for preoperative factors.

Results: Among the 103 patients, 92 were selected using PSM. The cumulative overall survival rates at 1, 3, and 5 years for the TACE?+?RFA group were 97.4%, 70.4%, and 60.4%, respectively, which were significantly higher than those for the TACE group (92.7%, 55.7%, and 22.8%, respectively, p?=?.045). The recurrence-free survival rates at 0.5, 1, and 2 years for the TACE?+?RFA group were 80.0%, 58.6%, and 33.3%, respectively, which were significantly higher than those for the TACE group (34.5%, 8.8%, and 2.9%, respectively, p?p?=?.036).

Conclusions: The addition of RFA to TACE improved cumulative overall and recurrence-free survival in patients with intermediate-stage HCC, especially in patients with AFP <100.     

Short-term interval combined chemoembolization and radiofrequency ablation for hepatocellular carcinoma

AIM: To investigate hepatic function after combined transcatheter arterial chemoembolization (TACE) and radiofrequency ablation (RFA) with a short-term interval (0-2 d).METHODS: A total of 115 patients with compensated liver cirrhosis underwent RFA combined with TACE at a time-interval of 0-2 d for the treatment of hepatocellular carcinoma (HCC) < 5.0 cm. There were 21 patients who received further hepatic directed treatment altering liver function within 12 mo after the combined therapy for HCC-recurrence, and were excluded. The remaining 94 patients who survived without HCC-recurrence were included in this retrospective study.RESULTS: At 1 mo after treatment, Child-Pugh scores (CPs) remained unchanged in 89 of 94 patients (94.7%), and transiently increased by one-point in 5 patients (5.3%). However, the score returned to baseline score at 3 mo and was maintained until 6 mo in all patients. The baseline CPs of 8 or more was identified as a factor for transient rise of CPs after the treatment (CPs 8/9 vs 5/6/7; 21.4% vs 2.5%; P = 0.022). At 12 mo follow-up, CPs was unchanged in 90 patients (95.7%), and increased by one-point in 4 patients (4.3%). The rise of CPs at 12 mo was not statistically associated with the initial transient rise of CPs. There were procedure-related complications in 3 patients (3.2%), but the complications were resolved by medical and interventional treatments without hepatic functional sequelae.CONCLUSION: The combined TACE and RFA with an interval of 0-2 d are safe for the management of HCC < 5 cm in cirrhotic patients.     

Transcatheter arterial chemoembolization followed by immediate radiofrequency ablation for large solitary hepatocellular carcinomas

AIM: To assess the technical safety and efficacy of transcatheter arterial chemoembolization (TACE) combined with immediate radiofrequency ablation (RFA) for large hepatocellular carcinomas (HCC) (maximum diameter ≥ 5 cm). METHODS: Individual lesions in 18 patients with HCCs (mean maximum diameter: 7.5 cm; range: 5.1-15.5 cm) were treated by TACE combined with percutaneous RFA between January 2010 and June 2012. All of the patients had previously undergone one to four cycles of TACE treatment. Regular imaging and laboratory tests were performed to evaluate the rate of technical success, technique-related complications, local-regional tumor responses, recurrence-free survival time and survival rate after treatment.RESULTS: Technical success was achieved for all 18 visible HCCs. Complete response (CR) was observed in 17 cases, and partial response was observed in 1 case 1 mo after intervention. The CR rate was 94.4%. Local tumors were mainly characterized by coagulative necrosis. During follow-up (2-29 mo), the mean recurrencefree survival time was 16.8 ± 4.0 mo in 17 cases of CR. The estimated overall survival rate at 6, 12, and 18 mo was 100%. No major complications were observed. Levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in the blood of 17 patients transiently increased on the third day after treatment (ALT 200.4 ± 63.4 U/L vs 24.7 ± 9.3 U/L, P < 0.05; AST 228.1 ± 25.4 U/L vs 32.7 ± 6.8 U/L, P < 0.05). Severe pain occurred in three patients, which was controlled with morphine and fentanyl. CONCLUSION: TACE combined with immediate RFA is a safe and effective treatment for large solitary HCCs. Severe pain is a major side effect, but can be controlled by morphine.

Meta-analysis of radiofrequency ablation in combination with transarterial chemoembolization for hepatocellular carcinoma

AIM: To compare radiofrequency ablation (RFA) and transcatheter arterial chemoembolization (TACE) with RFA monotherapy in hepatocellular carcinoma (HCC). METHODS: We searched PubMed, Medline, Embase and Chinese databases (CBMdisc and Wanfang data) for randomized controlled trails comparing RFA plus TACE and RFA alone for treatment of HCC from January 2000 to December 2012. The overall survival rate, re-currence-free survival rate, tumor progression rate, and safety were analyzed and compared. The analysis was conducted on dichotomous outcomes and the standard meta-analytical techniques were used. Pooled odds ratios (ORs) with 95%CIs were calculated using either the fixed-effects or random-effects model. For each meta-analysis, the χ2 and I2 tests were first calculated to assess the heterogeneity of the included trials. For P<0.05 and I 2>50%, the assumption of homogeneity was deemed invalid, and the random-effects model wasused; otherwise, data were assessed using the fixed-effects model. All statistical analysis was conducted us-ing Review manager (version 4.2.2.) from the Cochrane collaboration. RESULTS: Eight randomized controlled trials were identified as eligible for inclusion in this analysis and included 598 patients with 306 treated with RFA plus TACE and 292 with RFA alone. Our data analysis indicated that RFA plus TACE was associated a sig-nificantly higher overall survival rate (OR 1-year=2.96, 95%CI: 1.84-7.74, P<0.001; OR 2-year=3.72, 95%CI: 1.24-11.16, P=0.02; OR 3-year=2.65, 95%CI: 1.81-3.86, P<0.001) and recurrence-free survival rate (OR 3-year=3.00, 95%CI: 1.75-5.13, P<0.001; OR 5-year=2.26, 95%CI: 1.43-3.57, P=0.0004) vs that of RFA alone. The tumor progression rate in patients treated with RFA alone was higher than that of RFA plus TACE (OR=0.60, 95%CI: 0.42-0.88, P=0.008) and there was no significant difference on major complications between two different kinds of treatment (OR=1.20, 95%CI: 0.31-4.62, P=0.79). Additionally, the meta-analysis data of subgroups revealed that the

Computed tomography-guided transpulmonary radiofrequency ablation for hepatocellular carcinoma located in hepatic dome

AIM:To determine the feasibility of performingcomputed tomography(CT)-guided transpulmonaryradiofrequency ablation(RFA)for hepatocellularcarcinoma(HCC)located in the hepatic dome.METHODS:A total of seven patients with HCCcomprising seven nodules located in the hepatic domewere treated from April 2004 to December 2004.CT-guided transpulmonary RFA was performed using acool-tip type electrode(Radionics Company)based ona standardized energy protocol.All tumors located inthe hepatic dome were not detectable by the usualultrasound(US)methods.The lesion diameters rangedfrom 15 to 27 mm.RESULTS:RFA was technically feasible in all thepatients.The puncture procedure was performed twiceor less and the total average performance time was40.6 min.Local tumor control was achieved in all thepatients.The necrosis diameter ranged from 25 to35 mm.The mean follow-up period was 9.6(7-14 mo)mo.There was no local recurrence at the follow-uppoints.Pneumothorax requiring pleural drainage was themain complication,which was observed in two of theseven patients(28.6%).However,it improved with chestdrainage tube,and the tube could be removed within2-3 d.No other major complications were observed. CONCLUSION:CT-guided puncture is useful for thetreatment of tumors located in the hepatic dome whichare hardly detectable by US,even though pneumothoraxsometimes may occur as a complication.In the caseswith adhesion in the pleura for which artificial pleuraleffusion methods are not appropriate,CT-guided RFA isthus considered to be an alternative treatment for HCClocated in the hepatic dome.

Outcome of transarterial chemoembolization in patients with inoperable hepatocellular carcinoma eligible for radiofrequency ablation

AIM: To evaluate the outcome of transarterial chemoembolization (TACE) in patients with unresectable hepatocellular carcinoma (HCC)<5 cm in diameter eligible for radiofrequency ablation (RFA). METHODS: The treatment-related mortality, morbidity, long-term survival, and prognostic factors of HCC patients who had TACE and fulfilled the present inclusion criteria for RFA were evaluated. RESULTS: Of the 748 patients treated with TACE between January 1990 and December 2002,114 patients were also eligible for RFA. The treatment-related mortality and morbidity were 1% and 19%, respectively. Survival at 1, 3, and 5 years was 80%, 43%, and 23%, respectively. Older age and a high albumin level were associated with a better survival, whereas a high a-fetoprotein level (AFP) and the size of the largest tumor >3 cm in diameter were adverse prognostic factors in multivariate analysis. CONCLUSION: The morbidity, mortality, and survival data after TACE for small HCCs eligible for RFA are comparable to those reported after RFA in the literature. Our data suggest the need for a randomized comparison of the two treatment modalities for small HCCs.
