title: [Assessment of the efficacy of cancer procoagulant (CP) activity evaluation in the oncological diagnosis of the urinary system].
abstract: Many studies have been carried out to develop unfailing diagnostic methods that could improve cancer detection. There are available cancer markers of relatively low sensitivity and specificity, which makes a reason why they not always let detect neoplasm at their earliest stage. There is a new protease cysteine enzyme named cancer procoagulant (CP) isolated from rabbit V2 Ca neoplasm and characterized by Gordon et al in 1975. Because of its exclusive presentation in the cancer tissues and blood serum of the patients with tumor, this neoplasm-cell-originated protein seems to be a new biochemical cancer disease marker. The elevated activity of CP was found in the cancers of pancreatic, breast, lung, alimentary and urinary system. The blood serum CP activity levels in the patients with renal, bladder, and prostate cancers were determined statistically higher as compared to controls but the difference varied depending on the mentioned organ of the urinary system. The CP highest activity levels was determined in the patients with prostate cancer, lower ones in bladder carcinoma ones and the lowest ones in individuals with renal tumours. That is why it appears to be justifiable to apply the determination of the CP in the oncological diagnosis in the urinary system.
