[Cancer procoagulant (CP): the new biochemical marker in oncologic diagnosis].

: This review describes the physicochemical and biological properties of cancer procoagulant (CP). This procoagulant is cysteine protease which directly activates coagulation factor X to factor Xa. CP is found in the tissues and blood of subjects suffering from cancer so its determination could be very useful in diagnostics and prognostics of cancer disease.
