Core Tip

Core tip: The liver has a unique capacity for regeneration after cellular damage or partial removal of tissue, and modern liver surgery relies on this property. Liver regeneration is a complex process involving a large array of growth factors, cytokines and cells to restore hepatic mass and function. Experimental and clinical data indicate that the regeneration signals facilitate the growth of both primary and secondary liver tumors and can alter their malignant potential. This is an important mechanism underlying recurrence after liver surgery. New therapeutic strategies founded on better insight into the relationship between liver regeneration and tumor biology are needed.
