Traitement non chirurgical du carcinome hépatocellulaire. Une vision d'ensemble

Surgery is often not a treatment option in patients with hepatocellular carcinoma with the numerous limitations of liver transplantation or surgical resection due to coexisting cirrhosis in the later case. Non-surgical treatments deal with 3 types of methods: local ablation with curative purpose, transarterial treatments with many technical variants and systemic treatment. Local treatments rely on chemical or thermic agents to achieve ablation of liver lesions, which not exceed initially 3 cm in diameter. The use of radiofrequency ablation allows now larger limits. Intra-arterial treatment usually combines intra-arterial chemotherapy with embolisation of hepatic artery in a procedure called chemoembolisation. Its antitumoral effect mainly due to ischemia is well documented but the influence on survival remains controversial. Finally systemic treatments have yet to be demonstrated useful: new agents and new randomised trials are still needed.
