[Diagnostic value of the determination of serum hexokinase activity in thyroid cancer and autoimmune thyroiditis]

The blood serum hexokinase (HK) level was studied in 122 patients suffering from thyroid diseases. Relatively low level of HK activity (3.96 +/- 0.78 ME) was seen in the blood of patients with thyroid malignant tumor and its rise was observed in all the patients with non-tumor injuries of this organ: in nodular euthyroid goitre 1.38 +/- 0.25 ME; in diffuse-toxic goitre 0.83 +/- 0.67 ME. The blood serum HK activity (3.43 +/- 0.73 ME) of patients with autoimmune thyroiditis did not statistically differ from that of the patients suffering from thyroid cancer.
