Abstract
In Western countries, most of the patients with hepatocellular carcinoma (HCC) are not eligible for curative treatments. Intra-arterial treatments have a palliative effect that could lead to extensive tumour necrosis and therefore have been widely used. Arterial embolization, Lipiodol-targeted chemoembolization and intra-arterial injection of radioactive iodine mixed with Lipiodol provided promising results in terms of tumoral growth, but were also responsible for severe side-effects, particularly in patients with cirrhosis. Their influence on survival has been assessed by randomized trials with contradictory results. In patients with advanced cases, embolization alone has limited or no influence on survival, and chemoembolization provided a beneficial effect mostly in patients with viral liver diseases, without liver failure, and with an adequate portal flux. The effects of radioactive iodine either in the treatment of advanced cases or the prevention of recurrences after a curative treatment must be investigated further.
