Abstract:Objective To explore the effects of ultrasound-guided laparoscopic radiofrequency ablation(LRFA) on the immunological function and clinical efficacy in patients with special or high-risk location small primary liver cancer.Methods The clinical data of 32 patients with small primary special or high-risk location heptocellular carcinoma undergoing ultrasound-guided laparoscopic radiofrequency ablation(LRFA group) from January 2012 to December 2017 in Department of Hepatobiliary and Pancreatic Surgery, the Central Hospital of Edong Healthcare Group, and 28 patients undergoing laparoscopic hepatectomy(LH group) during the same period were retrospectively analyzed. There were 25 males and 7 females in LRFA group, aged 38-84(61.13±12.30) years. In LH group, there were 23 males and 5 females, aged 35-80(60.07±12.90) years. Postoperative immune conditions, postoperative complications, radical surgery rates and disease-free survival rates between the two groups were compared.Results Operations in two groups were all successful without perioperative deaths. The radical operation rate of LRFA group and LH group was 96.9%(31/32) and 100.0%(28/28), respectively(P>0.05).All patients were followed up for 3-72 (46.8±18.5) months. Compared with LH group, CD3+, CD4+, CD8+ and CD4+/CD8+ increased significantly at 4 and 8 weeks after operation in LRFA group (all P values<0.05). Eight weeks after surgery, CD3+, CD4+, CD8+, CD4+/CD8+ of LRFA group were significantly increased (all P values<0.05). Incidence of postoperative complications had no statistical difference between two groups(P>0.05). The disease-free survival time of LRFA group was significantly longer than that of LH group. Postoperative disease-free survival rates of 1, 2 and 3 years for LRFA group were 93.7%, 81.3%, 56.3%. In LH group the rates were 82.1%, 71.5%, 42.9%, which had significant statistical differences with those in LRFA group(all P values<0.05).Conclusions By ultrasound-guided laparoscopic radiofrequency ablation, we can not only locate accurately and observe the ablation zone in real-time, we can also broad the application scope of radiofrequency ablation, protect immunological function and improve disease-free survival rates. Ultrasound-guided laparoscopic radiofrequency ablation has become the main method of minimally invasive treatment for special or high-risk location small primary liver cancer.
