  • Large Hepatocarcinoma: Treatment with RadioFrequency Ablation

    Objective To explore efficacy and safety of radiofrequency ablation (RFA) in the treatment of large hepatocarcinoma. MethodsFortythree cases of large hepatocarcinoma underwent RFA with the expandable cluster electrode,eight of all cases had undergone transcatheter artery chemoembolization (TAE) for 1-2 sessions within 2 months before RFA; the tumors were 5-10 cm in diameter, mean 7.5 cm. Hepatic function examination, alphafetoprotein, enhanced CT scans,color ultrasonography and needle biopsy were performed,pre and posttreatment. Complete necrosis was evaluated by dynamic enhanced CT scans and biopsy. Therapeutic time and sessions of RFA,length of stay in hospital and complications of RFA were observed; and thirtynine of 43 cases after RFA were followed up for 12-18 months.ResultsFortythree cases of large hepatocarcinoma received RFA for 67 sessions, 1-3 sessions per case,mean 1.6 sessions; therapeutic time 55-150 min,mean 75 min; length of stay in hospital 3-15 day, mean 8.7 day; major complications of RFA included local skin burn of electrode board in 2 cases (4.6%) and moderatetolarge right pleural effusion in 3 cases (7.0%),overall complications rate was 11.6%; complete necrosis was achieved in 41.0% of cases which were evaluated by dynamic enhanced CT scans at least 6 months followed RFA; of thirtyone cases of positive AFP, AFP level became negative in 3,decreased obviously in 5 within 6-12 months after RFA; in 12-18 months followup,oneyear survival rate was 69.2%.Conclusion RFA appears to be safe, effective and minor invasive for the treatment of large hepatocarcinoma.

  • Effect of High Intensity Focused Ultrasound on Immunity of Patients with Advanced Primary Liver Cancer

    【Abstract】ObjectiveTo investigate the effect of high intensity focused ultrasound (HIFU) on the immunity of patients with advanced primary liver cancer (PLC). MethodsForty cases of PLC admitted to our institution from Mar. 2003 to Dec. 2003 were included in this study. Patients were divided into 2 groups and received either HIFU or radiofrequency ablation (RFA) treatment randomly. CD3, CD4, CD8, CD4/CD8, NK, IL-2, TNF were chosen to assess the immune status before and after treatment. The results were compared statistically. ResultsThe survival rate after HIFU was 80.0%, 61.1%, 42.9%, 33.3% at 3 months, 6 months, 9 months and 1 year respectively, which was similar to that after RFA treatment. The changes of immunity parameters of CD3, CD4, CD8, CD4/CD8, NK, IL-2 and TNF were not significant after HIFU treatment. In addition, the differences of those parameters between HIFU group and RFA group were insignificant. ConclusionThere are no detrimental effects on immunity in the early period after HIFU treatment.
