Transcatheter arterial chemoembolization combined with radiofrequency ablation in treatment of renal cell carcinoma / 中国介入影像与治疗学

ABSTRACT

Objective To evaluate the safety and effectiveness of TACE with radiofrequency ablation (RFA) in treatment of renal cell carcinoma.Methods Data of 23 cases of renal cell carcinoma were retrospectively analyzed.Firstly all patients were treated with renal TACE,and then RFA under the guidance of ultrasound and CT was performed 3 to 4 weeks later.The therapeutic effects were evaluated by enhanced CT or MR scans during the follow-up period.Meanwhile,the changes of Karnofsky Performance Status (KPS) scores and renal functions between preoperative and postoperative periods were also evaluated.Results To the end of the follow-up,in all 23 patients 21 cases (21/23,91.30％) survived and 2 cases died (2/23,8.70 ％).KPS scores and serum creatinine levels were observed in all 23 patients at the initial stage and the end of the follow-up period,there were no significant differences (all P＞0.05).At the end of follow-up,16 cases were complete remission,5 were partial remission and 2 were progressive disease.Conclusion TACE combined with RFA is a safe and effective method in treatment of renal cell carcinoma with less trauma,less complication and more effective.
