Abstract: Objective The aim of this study was to investigate the short-term efficacy of radiofrequency ablation (RFA) with cold circulation in the treatment of patients with primary liver cancer (PLC) and the change of peripheral blood fegulatory T cells (Treg). Methods A total of 94 patients with PLC were admitted to our hospital between April 2018 and April 2019, and were randomly divided into observation group (n=47) and control group (n=47). The patients in the control group received hepatic artery chemoembolization (TACE), while those in the observation group received RFA with cold circulation under the guidance of color ultrasound. The percentages of peripheral blood Treg cells were detected by TCM. Results At the end of three month after operation, the complete response, partial response and disease stable rates in the RFA-treated patients were 42.6%,40.4% and 6.4%, and the disease control rate was 89.4%, all significantly higher than (31.9%, 27.7%, 12.8%, and 72.3%, P<0.05】 in TACE-treated patients except for disease stable rate; at presentation, serum ALT, ALP, total bilirubin and the percentage of peripheral blood cells in RFA-treated patients were (96.4±22.4)U/L, (184.5±30.5)U/L,(18.5±5.8)μmol/L and 9.5±1.5)%, not significantly different compared to in TACE-treated patients, while serum ALT, ALP and percentage of peripheral blood Treg cells in RFA-treated patients were (35.1±5.8)U/L,(84.5±15.8)U/L and (6.2±0.5)% after operation, all significantly lower than in TACE-treated patients; the incidence of post operation complications such as abdominal distension, diarrhea, peritonitis, fever and gastrointestinal bleeding was 8.5%, significantly lower than 25.5% (P<0.05)in TACE-treated group.Conclusion The application of RFA with cold circulation under color ultrasound guidance in treatment of patients with PLC could get excellent short-term efficacy, which might reduce peripheral blood Treg cells, and has a higher safety.
