[Combined percutaneous ethanol injection through liver puncture and transcatheter hepatic arterial chemoembolization
1Department of Diagnostic Radiology, Cancer Institute (Hospital), Chinese Academy of Medical Sciences, Peking Union Medical College, Beijing 100021, China.
Objective:
To study the therapeutic effects of transcatheter arterial chemoembolization (TACE) combined with beta-ultrasound guided percutaneous ethanol injection (PEI) at multiple points for hepatocellular carcinoma.
Methods:
Eighty-seven patients with hepatocellular carcinoma were divided into two groups: Group A, 45 patients were treated with TACE only, group B, 42 patients were treated with TACE plus PEI.
Results:
In group A patients, the 1-, 2-, and 3-year survival rates were 66.7%, 41.4%, and 21.4%, respectively. Only 26.1% of cancer specimens showed complete necrosis by pathologic examination in group A. In group B, the 1-, 2-, and 3-year survival rates were 97.1%, 85.71% and 65.71%, respectively, with complete necrosis in 81.8%.
Conclusion:
The therapeutic effects of transcatheter arterial chemoembolization combined with percutaneous multiple point ethanol injection through liver puncture is much better than that of TACE alone.
