Abstract:
Objective To sum up the effect and experience in radiofrequency ablation(RFA) for liver cancer(LC). Methods The clinical data of 102 patients with LC treated by percutaneous and intraoperative RFA were analysed retrospectively. Results RFA was used to treat 195 tumors (median diameter 5.6 cm,ranging from 1.5 to 9.5 cm) in 102 patients.Of them, primary liver cancer was found in 80 patients( 78.4%),and metastatic liver tumor was in 22 patients(21.6%). Percutaneous RFA(PRFA) and intraoperative RFA(IRFA) was performed in 77 patients(75.5%) and 25 patients(24.5%) respectively. There was no severe complications after RFA in this series. All of the 102 cases had been followed up for 3～24months,AFP positive returned to negative in 70.3%(52/74)of the patients.The rate of concreted necrosis of liver cancer showed by CT was 88.2%(90/102). The 1 year survival rate was 93.8%.Conclusions RFA is a safe and effective treatment for patients with LC. Patients with small and readily accessible tumor are the indications of PRFA;while the patients with large,multiple,perivascular or otherwise inaccessible liver tumor are also the indications for IRFA.The adoption of the TACE and other methods to occlude the vascular inflow can improve the efficacy of RFA.
