Persistent hypoglycemia in patients with liver cancer.

Hypoglycemia in liver cancer occurs due to the failure of the liver to fulfill body glucose demand because the liver parenchyma has been largely replaced by the tumor, in addition to the high production of insulin growth factor (IGF). Hypoglycemia is often caused by islet cell and non-islet cell tumors, with a higher occurrence in non-islet cell tumors due to paraneoplastic syndrome and the high metabolic requirements of the tumor. The mainstay of NICTH treatment is treating the tumor with cytoreduction. However, in an advanced stage, cytoreduction therapy is often challenging to conduct. Beneficial supportive treatments for controlling blood glucose are frequent meals, dextrose infusion, and the injection of steroids and glucagon. Steroids play a beneficial role in the treatment of persistent hypoglycemia in hepatocellular carcinoma by stimulating gluconeogenesis and increasing lipolysis. Steroids also have roles in the inhibition of peripheral glucose intake, suppression of big IGF-2 production, and modulation of the GH-IGF axis.
