Radiofrequeney ablation in treating unresectable liver cancer / 中国综合临床

ABSTRACT

Objective To investigate the effect of radiofrequency ablation (RFA) in treating unresectable liver caneer. Methods 43 patients(78 lesions) who suffered from unresectable liver cancer were treated with cool-tip RFA from May 2006 to November,2008 in our hospital. 26 cases were treated with RFA in laparotomy besides with reseet of lesion in 6 eases and with alinjection in 5 cases,while 17 eases were treated only with percutaneous RFA. Results All patients were diagnosed by CT and B-ultrasound or MRI,among whom 18 cases were confirmed with primary hepatic carcinoma, 12 eases experienced recurrence following resect of primary hepatic carcinoma and 13 eases developed metastatic carcinoma;Every patient was followed up with AFP, abdominal B-ultrasound, CT scans or MRI from 1 to 28 months after treatment (mean 13.6 months). Before procedure, AFP increased in 20 eases which recovered within 3 months of treatment. 2 cases were suspected having residual on CT scan ,6 cases were found with new masses on liver on CT scan, 1 case complicated with gastrointestinal fistula and then died of systemie metas-tasis 3 months later,1 ease died of postoperative bleeding and 1 died of bleeding and infection after reseet + RFA treatment,and 3 cases died of multi-metastasis during following up who survived on average of 6 months. Conclu-sions B-ultrasound -guided cool-tip circulation RFA is an effective and safe method in treating unresectable liver cancer.
