經皮超音波導引射頻燒灼術(RFA)治療單一惡性肝臟腫瘤病患的回顧
Percutaneous Ultrasound-guided RFA for the Treatment of Solitary Malignant Hepatic Tumor
摘要
射頻燒灼術(RFA)可以用於治療原發性或侵犯轉移性肝臟腫瘤，是外科手術以外另一種變通的局部治療方式。本文回顧追蹤本部門2002年到2006年的RFA 治療結果，共有35例單一惡性肝臟腫瘤病患接受超音波導引經皮射頻燒灼術。所有病例均採用多電極(RITA)射頻探針。我們比較單一病灶的原發性肝癌(Group H)病例18人，與侵犯轉移性肝臟腫瘤(Group M)病例17人。在單一病灶接受RFA 治療完成後，侵犯轉移性肝臟腫瘤病例，比原發性肝癌病例較快在肝臟內發現新病灶(肝臟內復發)；一年內的肝臟內復發率較高(Group M：41.2%；Group H：16.7%)。

Radiofrequency ablation (RFA) is now widely used to treat primary hepatocellular carcinoma (HCC) and metastatic hepatic tumors. In this report, we reviewed the outcome of 35 patients with solitary malignant hepatic tumor treated with percutaneous ultrasound-guided RFA using multitine needle electrodes (RITA , Mountain View, CA, USA) from 2002 to 2006. We categorized patients with only one HCC as Group H (18 patients), and those with only one invasive metastatic hepatic tumor as Group M (17 patients). We found that after the completion of RFA treatment, patients of Group M had a higher intrahepatic recurrence rate in 1st year follow-up examinations as compared with those of Group H. (Group M: 41.2% vs. Group H: 16.7%).
