Summary
Variations of antithrombin III were studied in a non-ran-domized population of consecutive
cancer cases admitted to a referral hospital. Differences between functional and immunologic
assay were observed.
Decreases were observed in both assays when compared to a population of hospitalized
controls. Patients with cancer of the colon, ovary and prostate showed a deficiency
of antithrombin III more frequently than other common tumors. When all tumor cases
were subdivided into those in remission compared to those with metastases, a significant
decrease in antithrombin III also could be shown.
Metastases to the liver were strikingly common in cancer patients with decreased antithrombin
III. In these patients, the decrease in antithrombin III could be statistically correlated
with reduction in serum albumin.
