Induction of transient hyperglycaemia in cancer patients

Serum glucose levels up to 700 mg/dl were achieved and maintained for 3 h in patients with advanced metastatic cancer by infusion of concentrated glucose solutions. Even with infusions of large amounts of glucose, the maximum sustainable level of serum glucose did not exceed 700 mg/dl. The apparent ceiling of serum glucose level appeared to be due to a large and rapid loss of glucose from the kidneys. With adequate fluid volume replacement there was no rebound hypoglycaemia and there was no significant changes in haematocrit or electrolytes.
