ABSTRACT
Objective To investigate the clinical effects of autologous tumor immune cells (DC-CIK)assisted interventional therapy in the treatment of advanced primary liver cancer.Methods Totally 76 patients with advanced primary liver cancer were divided into 2 groups with 38 cases in each group by random number table method.The control group were merely treated with interventional therapy while the ob-servation group were treated with autologous DC-CIK cell assisted interventional therapy.The short-term curative effect,adverse reactions,liver function indexes before and after treatment,alpha fetal protein (AFP)and changes of immune function were compared between the 2 groups. Results There was no statistically significant difference in short-term curative effect and incidence of adverse reactions between the 2 groups (P >0.05).After treatment,the levels of AST,ALT and AFP in the observation group [(30.4 ±6.0)u/L,(45.2 ±3.8)u/L,(168.5 ± 49.3)mg/L]were significantly lower than those in the control group [(65.1 ±6.3)u/L,(61.8 ±5.3)u/L,(315.2 ±39.5)mg/L],and the differences were statistically significant (P <0.05).After treatment,CD3 +,CD4 + and CD4 +/CD8 + in the observation group were significantly higher than those in the control group (P <0.05).Conclusion Autologous DC-CIK cell assisted interventional therapy can sig-nificantly improve the liver function of patients with advanced primary liver cancer,and it can reduce the level of tumor marker AFP and sig-nificantly improve the immune function of patients.
ABSTRACT
Objective To evaluate the safety and local control rate and short term survival status of the treatment for primary liver cancer by microwave ablation.Methods From January 2006 to January 2014,a total of 209 lesions in which the average diameter was 3.92 cm in 187 patients was performed the microwave ablation therapy.There were 12 lessions adjacent to lung,diaphragm,abdominal wall,stomach,colon and gallbladder area. Enhanced CT examination was performed one month after ablation and the imaging data,liver function,AFP level and quality of life were followed up every three month to evaluate the effectiveness.Results 88.99 percent of le-sions achieved complete elimination after an average 1.35 times ablation.The completed elimination ratio for small lesions less than 3 cm was up to 100%.Local tumor progression occurred in 23 lesions.Seventheen patients had mild complications.The slight complication rate was about 5.82%.Death and other serious complications did not occur in this study.Conclusion Microwave ablation is safe and feasible for the lesions of liver cancer with live cancer less than 5 cm,which is located in the special dangerous area of liver cancer.Microwave ablation can significantly prolong the survival time of patients,especially for small HCC patients with <3cm.
