Radiofrequency ablation of liver tumors: experience with open and percutaneous approach.
Artigo em Inglês | IMSEAR | ID: sea-64909
ABSTRACT

BACKGROUND:

Radiofrequency ablation (RFA), a thermal coagulation technique, has been used for ablation of primary and secondary liver tumors.

METHODS:

Over a 24-month period, 41 patients, including 20 with hepatocellular cancer (HCC), 14 with liver metastases from colorectal tumors and 7 with metastases from other tumors, underwent RFA in our institution. Ablation was done using intra-operative (n=27) or percutaneous ultrasonographic (n=14) guidance. A zone of ablation larger than the size of the lesion on CT scan indicated successful RFA.

RESULTS:

The mean size of lesions was 4.9 cm for HCC and 3.1 cm for metastases. Among 20 patients with HCC, 16 had complete tumor ablation and one had failure of localization. All patients with liver metastases had successful tumor ablation. There was no procedure-related death. Two patients had hemoperitoneum and one experienced skin burn. During a median follow up of 16 months, five patients with HCC and two with colorectal metastases died. One patient had tumor recurrence at the ablation site and two developed fresh solitary metastatic lesions; all three are disease-free after repeat ablation treatment.

CONCLUSIONS:

RFA is a safe and promising technique for the treatment of non-resectable HCC and liver metastases, in the short term.
