Serum cholinesterase levels in patients with cancer.
Serum cholinesterase levels were determined in 180 patients with carcinoma and in 146 normal subjects. Serum cholinesterase activity was significantly lower in patients suffering from cancer than in normal controls, though still within the normal range. The degree of depression of serum cholinesterase activity was influenced by the extent to which the malignancy had spread and by the site of the primary lesion.
