Efficacy and safety of microwave ablation and radiofrequency ablation in the treatment of hepatocellular carcinoma: A systematic review and meta-analysis.

ABSTRACT:

Background

Hepatocellular carcinoma (HCC) is one of the most common malignant tumors. Surgical resection is often only possible in the early stages of HCC and among those with limited cirrhosis. Radiofrequency ablation and Microwave ablation are 2 main types of percutaneous thermal ablation for the treatment of HCC. The efficacy and safety between these 2 therapy methods are still under a debate.

Objective

To compare the efficacy and safety of Radiofrequency ablation and Microwave ablation in treating HCC.

Methods

PubMed, EMBASE, the Cochrane databases and Web of Science were systematically searched. We included randomized controlled trials and cohort studies comparing the efficacy and safety of Radiofrequency ablation and Microwave ablation in HCC patients. Outcome measures on local tumor progression, complete ablation, disease-free survival, overall survival, or major complications were compared between the 2 groups. The random effect model was used when there was significant heterogeneity between studies, otherwise the fixed effect model was used.

Results

A total of 33 studies, involving a total of 4589 patients were identified, which included studies comprised 7 RCTs, 24 retrospective observational trials, and 2 prospective observational trial. Microwave ablation had a lower local tumor progression than Radiofrequency ablation in cohort studies (OR = 0.78, 95% CI 0.64-0.96, P = .02). Complete ablation rate of Microwave ablation was higher than that of Radiofrequency ablation in cohort studies (OR = 1.54, 95% CI 1.05-2.25, P = .03). There was no significant difference in overall survival and disease-free survival between the 2 groups. Meta-analysis showed that there was no significant difference in the main complications between Microwave ablation and Radiofrequency ablation.

Conclusions

Microwave ablation has higher complete ablation and lower local tumor progression than Radiofrequency ablation in the ablation treatment of HCC nodules. There was no significant difference in overall survival between the 2 therapy methods.

Project description:BackgroundSeveral randomized controlled trials (RCTs) compared the effects of laparoscopic hepatectomy (LH) and radiofrequency ablation (RFA) for the treatment of hepatocellular carcinoma (HCC), but the results have remained inconsistent. Hence, a meta-analysis and a systematic review of these treatment modalities are necessary to evaluate their efficacy and safety for HCC treatment.MethodsFrom the inception of this meta-analysis and review until August 31, 2019, we searched Medline, PubMed, EMBASE, Cochrane Library, China National Knowledge Infrastructure, Wanfang Database, and China Biomedical Literature Database for RCTs involving LH and RFA treatments of patients with HCC. The studies were screened and the data from these articles were extracted independently by two authors. Summary odd ratios (OR) or mean differences (MD) with 95% confidence intervals (CI) were calculated for each outcome with a fixed- or random-effect model. The outcomes for effectiveness evaluations included duration of surgery, estimated bleeding volume, incidence of blood transfusion during surgery, duration of hospital stay, and the outcome for safety included the incidence of cancer recurrence.ResultsSeven RCTs with a total of 615 patients were identified, 312 and 303 of which underwent RFA and LH treatments, respectively. The duration of surgery (MD = -99.04; 95% CI: -131.26--66.82), estimated bleeding volume (MD = -241.97; 95% CI: -386.93--97.02), incidence of blood transfusion during surgery (OR = 0.08; 95% CI: 0.02-0.37), and duration of hospital stay (MD = -3.4; 95% CI: -5.22--1.57) in RFA treatment were significantly lower than those of LH treatment. However, the incidence of cancer recurrence was significantly higher for RFA treatment compared with LH treatment (OR = 2.68; 95% CI: 1.72-4.18).ConclusionsLH treatment is preferred over RFA treatment with a better radical effect, but RFA treatment is more beneficial with smaller trauma, development of less complications, and shorter operating time when compared with HCC treatment.
