Abstract:
Objective To study the value of B type ultrasonography guiding percutaneous radiofrequency ablation (PRFA) for hepatic cancer (HC). Methods 70 patients with primary or metastatic hepatic malignancies were treated by PRFA under ultrasound guidance through LeVeen multipolar array needle electrode and RF 2000. All patients were followed up by turnor marker, B type sounography and MRI monthly. Results PRFA were performed in 53 patients with hepatocellular carcinoma (HCC) and 17 cases with metastatic liver cancer. Liver function classfication was 53 cases in Child class A, 15 in class B and 2 in class C. In 21 patients with non-operated small HCC (≤5 cm), 12 of 17 patients with AFP positive were decreased to normal (70.6%) and decreased markedly in 4 (23.5%), and MRI showed the treated tumors were completely necrosis in 16 patients (76.2%). The 3, 6 month survival rates were 90.5%, 100% respectively in small HC groups, and 66.7% to 72.7% and 27.6% to 72.7% in large HC groups.Conclusions PRFA as a local thermal therapy is becoming a kind of new palliative treatment for hepatic malignancies, which not only is safe, minimally invasive, and effective for small ones; but also can be used with combination of TACE for larger ones.
