Laser Ablation for Intermediate and Advanced Hepatocellular Carcinoma With Portal Vein Tumor Thrombus

Not Applicable

Completed

• Conditions: Hepatocellular Carcinoma; Laser Ablation; Portal Vein Tumor Thrombus
• Interventions: Procedure: 3D-CRT; Procedure: LA

• Registration Number: NCT02724475
• Lead Sponsor: Eastern Hepatobiliary Surgery Hospital

Brief Summary

Hepatocellular carcinoma (HCC) is the fifth most-common cancer worldwide and the second most-common cause of cancer mortality. Liver resection is the first-line curative treatment for huge HCC. The 5-year overall survival (OS) rates after hepatic resection were range from 25% to 45% and the incidence of portal vein tumor thrombus (PVTT) for intermediate and advanced hepatocellular carcinoma patients were as high as 60%-90%. At present, there is no effective treatment for patients with PVTT. Laser ablation (LA) showed a good performance in eliminating the PVTT and the three-dimensional conformal radiotherapy (3D-CRT) with γ Ray (γ-knife) can also be used to treat patients with PVTT. But there still lack of evidence-based research to compare the clinical outcome of 3D-CRT with γ Ray and LA. In view of this, we aim to implement a randomized controlled study to find out an effective treatment for intermediate and advanced hepatocellular carcinoma patients with PVTT based on evidence-based research.
