大多数局限于肝脏的原发性或转移性的恶性肿瘤病人,由于肿瘤侵及两叶,转移灶超过4个,靠近大血管大胆管而不适宜手术。局部加热方法可使肿瘤细胞死亡,现报道对不能手术切除的肝癌病人应用射频切除的初步治疗结果。 病人和方法:自1996年1月1日至1998年3月31日,123例病人都经组织学证实为原发性或继发性肝脏恶性肿瘤,经临床、X线或手术都证实没有肝脏外疾病,以射频切除法(RFA)治疗。经皮肤或手术中于超声引导下用新型LeVeen单极排列式针状电极和RF2000型发生器进行治疗。
Most patients with primary or metastatic malignancies confined to the liver are not suitable for surgery because the tumor invades the two leaves and has more than four metastatic lesions and is close to the large blood vessels. The local heating method can cause tumor cells to die. The preliminary results of radiofrequency ablation for patients with unresectable liver cancer are reported. Patients and Methods: From January 1, 1996 to March 31, 1998, 123 patients were confirmed as histologically primary or secondary hepatic malignancies. No liver was confirmed by clinical, X-ray, or surgery. External diseases are treated with radiofrequency ablation (RFA). Ultrasound-guided treatment with the new LeVeen unipolar array of needle electrodes and the RF2000 generator was performed transcutaneously or intraoperatively.
