Comparative analysis of radiofrequency ablation and resection for resectable colorectal liver metastases

Abstract

Surgical resection revealed superior outcomes in the treatment of resectable CRLMs, particularly in cases with a hepatic tumor size > 3 cm.

Percutaneous Radiofrequency Ablation of Hepatic Metastases from Gastric Adenocarcinoma after Gastrectomy

“…Some authors reported that patients treated with RF ablation had comparable survival rates to patients who underwent surgical resection, whereas others reported RF ablation to be inferior to surgery. Ko et al (17) stated that the 5-year survival rates of patients with a tumor diameter o 3 cm did not show significant differences between an RF ablation group and surgical resection group (80.0% vs 49.5%; P ¼ .46), although the surgical resection group in that report showed a better 5-year OS for all tumor sizes. RF ablation offers the advantage of avoiding a second surgical approach that involves higher morbidity and mortality because of adhesions between anatomic structures.…”

“…The efficacy of RF ablation for colorectal hepatic metastasis was compared with surgical resection in previous retrospective studies (17)(18)(19). Although RF ablation therapy generally has shown a higher local recurrence rate than surgical resection, the OS rate for RF ablation is still controversial.…”

Radiofrequency Ablation versus Liver Resection for Colorectal Cancer Liver Metastasis

“…Thus, a total of 14 studies[311121314151617181920212223] with sample size ranging from 29 to 455 have been enrolled [Figure 1]. Of them, 1466 patients underwent LR and 739 patients underwent RFA.…”

Surgical hepatic resection vs. ultrasonographic guided radiofrequency ablation in colorectal liver metastases: what should we choose?

“…On the other hand, removing the hepatic parenchyma proved to be more clinically effective [52]. Sanghwa Ko et al [53] presented as well a retrospective study of 29 patients suggesting that RFA is significantly inferior to surgical resection in patients with tumor size higher than 3 cm. A recent study highlighted that the proper way to evaluate local site recurrences after RFA is by using a fluorine-18 deoxyglucose positron emission tomography (FDG) PET-CT within one year from the procedure.…”
