Abstract:
Objective To investigate the application value of ultrasound-guided percutaneous radiofrequency ablation (RFA) in treatment of liver metastases of malignant tumor.Methods Clinical and imaging data of 109 patients with liver metastases of malignant tumor who underwent ultrasound-guided percutaneous RFA during December 2009 to May 2015 were retrospectively analyzed.Results There were 31 patients (31/109,28.44%) with single liver metastases and 78 patients (78/109,71.56%) with multiple lesions.The primary tumors included colorectal,lung,breast,gastric,pancreatic,ovarian and prostate carcinomas.Among all 198 liver metastases,there were 151 (151/198,76.26%) with diameter < 3 cm and 47 (47/198,23.74%) with diameter ≥3 cm.One month after RFA,187 lesions (187/198,94.44%) were completely inactivated,while the other 11 lesions (11/198,5.56%) still had residual activity.One month later,the tumor markers improved obviously compared with those before treatment (all P<0.05).The incidence of intraoperative and postoperative complications was 6.42% (7/109).Conclusion Ultrasound-guided percutaneous RFA is a safe and effective treatment for patients with non-surgical indications of malignant liver metastases,which can partially control the survival activity of liver metastases.
