4. Transarterial chemoembolization (TACE):

This method uses the concept of injecting the chemotherapeutic agent intralesionally mostly cisplatin or adriamycin through the feeding artery of the tumor along with the addition of radio opaque contrast lipiodol and an embolic agent gel foam to trap the agent within the tumor for a longer period of time concentrating its effect on the lesion only.
It is mainly used for patients not suitable for resection and the tumor is larger than the extent of ablation and as a bridge in some candidates of liver transplant and the extent of tumor regression is followed monthly by CT scans to assess the successes of the procedure and detect any recurrence. It can also be done more than once like ablation till it gives the required effect.
