超声引导经皮消融治疗肿瘤的临床应用日益广泛,它在肝细胞癌(HCC)的治疗中最为成熟和作用最为显著有其内在原因.首先,肝脏及其局部病变在超声下显像良好,人路容易,疗效确实;其次,HCC的治疗难点一是患者多有肝功能损害,难以耐受侵袭度大的治疗方式,二是肿瘤有高度的复发倾向,需要反复多次治疗.经皮消融治疗的微创性、简便性恰好能对应这些难点. 相似文献

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. 相似文献

Background Percutaneous microwave ablation and radiofrequency ablation are two commonly used modalities for the treatment of hepatocellular
carcinoma; however, comparisons of them have not been documented adequately.
Methods Of 102 patients with biopsy-proved hepatocellular carcinoma, 49 (98 nodules) were treated percutaneously with microwave ablation
and 53 (72 nodules) with radiofrequency ablation. The local tumor control, complications related to treatment, and long-term
results of the two modalities were compared retrospectively.
Results The complete ablation rates were 94.9% (93/98) using microwave ablation vs 93.1% (67/72) using radiofrequency ablation (P = 0.75), and no significant differences were found either in the ablation of tumors of 3.0 cm or less (P = 1.00) or in those of more than 3.0 cm (P = 1.00) between the two modalities. The local recurrence rates were 11.8% (11/93) using microwave ablation vs 20.9% (14/67)
using radiofrequency ablation (P = 0.12), and there were no significant differences between the two modalities either in tumors of 3.0 cm or less (P = 0.36) or in those of more than 3.0 cm (P = 0.82). The rates of major complications associated with microwave ablation and radiofrequency ablation were 8.2% (4/49)
vs 5.7% (3/53; P = 0.71). The disease-free survival rates in the microwave ablation group were 45.9%, 26.9%, 26.9%, and 13.4% at 1, 2, 3,
and 4 years, respectively, and those in the radiofrequency ablation group were 37.2%, 20.7%, and 15.5% at 1, 2 and 3 years,
respectively (P = 0.53). The 1-, 2-, 3-, and 4-year cumulative survival rates for patients who underwent microwave ablation were 81.6%, 61.2%,
50.5%, and 36.8%, respectively, and for patients who underwent radiofrequency ablation the rates were 71.7%, 47.2%, 37.6%,
and 24.2%, respectively (P = 0.12).
Conclusions Percutaneous microwave ablation and radiofrequency ablation are both effective methods in treating hepatocellular carcinomas.
The local tumor control, complications related to treatment, and long-term survivals were equivalent for the two modalities. 相似文献
