Introduction:
Liver transplantation remains the main curative treatment method for hepatocellular carcinoma. There are several criteria for hepatocellular carcinoma to be eligible for liver transplantation, and it depends on main transplantation centers worldwide. Locoregional treatments and downstaging protocols are used for either to achieve these criteria or to prevent drop outs on the transplant waiting lists. But who can benefit from these bridging therapies effectively for the main purpose of curative treatment? Main contraindications are known for locoregional treatments like cirrhosis or low hepatic function, total main portal vein occlusion, and extrahepatic metastasis. HCCs, which are confined to liver but have high tumor burden, remains the main controversial issue.
Aim:
On this aspect, we reviewed the literature for downstaging protocols for hepatocellular carcinoma with their effect on survival and recurrence rates after liver transplantation.
Conclusion:
Although candidates for downstaging is still controversial, with the absence of main contraindications, LRT can be applied to selected HCCs, which have a certain degree of tumor burden.
