ABSTRACT
Objective To investigate the effectiveness and safety of TACE combined with radiofrequency ablation (RFA) and simple RFA in the treatment of hepatocellular carcinoma (HCC) with Meta-analysis.Methods The randomized controlled trials comparing of TACE combined with RFA and simple RFA in the treatment of HCC from January 2000 to November 2016 in Chinese and English literatures were included.Results A total of 12 articles were enrolled in this study.Meta-analyses showed that the 1-year,3-year overall survival rate and 1-year,3-year recurrence-free survival rate of TACE combined with RFA group were better than those of simple RFA group (all P＜0.05).And there was no significant difference between TACE combined with RFA group and simple RFA group in 5-year overall survival rate (P =0.07).There was no significant difference of the 1-year,3-year overall survival and 1-year and 3-year recurrence-free survival rate between TACE combined with RFA group and simple RFA group for tumor with maximum diameter ＜3 cm in HCC (all P＞ 0.05).There was no significant difference in the incidence of serious complication in both two groups (P=0.82).Conclusion The short-term and mid-term efficacy in the treatment of HCC using TACE combined with RFA is better than those using simple RFA,while the long-term efficacy of two kinds of therapy have no significant differences.

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.
ABSTRACT
Objective To explore the clinical value of lidocaine combined with remifentanil intravenous anesthesia for radiofrequency ablation of liver tumors.Methods Totally 1 252 patients with hepatic tumors treated by radiofrequency ablation were analyzed.RITA cluster multipole radio needles were used in all cases.Local anesthesia with lidocaine was used before percutaneous puncture,and the dosage was 2 mg/kg of body mass.The initial dose of remifentanil was injected with pump at 0.05 μg/(kg · min) during operation.Mean arterial pressure (MAP),heart rate (HR) and saturation of peripheral oxygen (SPO2) were recorded 24 h before radiofrequency ablation (T0),at the beginning of operation (T1),30 min after operation (T2) and at the end of surgery (T3).Visual analogue scale (VAS) was used to assess the analgesic effect during the whole ablation procedure.Results Radiofrequency ablation were successfully performed in 1 250 patients (1 250/1 252,99.84％).The average time was (59.02 ±14.63) min.The average dosage of remifentanil was (242.22± 22.73)μg.The average VAS score was (2.42± 1.13) points.Compared with the preoperative T0 time point,SPO2 did not change significantly at each time of T1,T2 nor T3,but MAP and HR were significantly higher than those before operation (both P＜0.05).VAS scores were significantly higher in patients with tumors size ＞5 em than those in patients with tumors size ≤5 cm (P＜0.05).VAS scores were significantly higher in patients with lesions under hepatic capsule and in diaphragm dome than in patients with lesions in other parts (both P＜0.05).Severe anesthesia related complications occured in 2 patients,related to the respiratory inhibitory effect of remifentanil,and the patients were completely recovered after corresponding treatment.Conclusion Lidocaine combined with remifentanil intravenous anesthesia for radiofrequency ablation of liver tumors can effectively relieve the pain in patients.Tumor size and tumor location are the main impact factors on analgesic effect.
