Abstract

In this study of 18 cancer patients, results of laboratory evaluation of a “hyper‐coagulable state” have been correlated with the extent of the disease and the functional activity of the patients. Most coagulation tests were normal. Higher levels of serum fibrinogen degradation products were associated with wider dissemination of disease. Fibrinogen survival time (t ~1/2~) was shorter in patients with extensive disease than in those with less extensive disease (P < 0.05); platelet t~1/2~ was also shorter in the former group, though not significantly. Coexistence of severest physical disability and extensive disease was associated with the most marked reduction of platelet and fibrinogen t~1/2~. There was little correlation between platelet and fibrinogen t~1/2~, thus suggesting independent mechanisms of destruction of the two blood components. We suggest that future studies of hemostatic changes in cancer patients should include assessment of impairment of physical performance of the patients, as well as the extent of the tumor.
