Ultrasound-guided radio frequency ablation becomes
Professor Chen Minhua et al of College of Clinical Oncology, Peking University adopted radio-frequency ablation (RFA) for the treatment of malignant tumors of the liver; after a period of one year of clinical practice and follow-up studies Professor Chen et al proved that this method provided an effective minimally invasive therapeutic tool for those cases of malignant tumors of the liver which were inoprerable surgically, also the method could serve as a means of local hemostasis for hemorrhage of ruptured liver tumors.
RFA treatment was carried out in 79 cases with primary liver cancer and 55 cases with metastatic liver cancer (134 cases and 195 foci). The treatment completely inactivated 177 tumor foci as seen on reinforced CT examination within one day or one month. The effective rate was 90.7% (31 patients had RFA treatment for 2-4 times); a 69.9 % shrinkage of the tumor in most of the patients 3 months after the treatment. In one patient with giant liver cancer complicated with massive hemorrhage got successful hemostasis with RFA treatment on emergency. All the cases treated with this method were followed-up for a period of 3-21 months and at present 129 cases (96.3 %) are surviving.
Ultrasound guided RFA for the treatment of malignant liver tumors is indicated in mono-focal lesions of less than 6 cm in diameter and those of 3-5 multiple foci of approximately 3 cm in diameter. The advantages of RFA treatment are its effectiveness, less complications, short period of treatment and multiple administrations; it provided a new means of minimally invasive treatment of liver cancer., 百拇医药
