ALTERATIONS IN COAGULATION AND FIBRINOLYSIS IN LUNG CANCER PATIENTS
Lung cancer has commonly been associated with to both clinical problems of thromboembolism and to biological alterations in -coagulation and fibrinolysis.We evaluated some coagulation and fibrinolytic parameters of the plasmatic coagulation and fibrinolytic system (Fibrinopeptide A (-FPA-) for enzimoimmunoassay, immunological tissue plasminogen activator (t-PA) for enzimoimmunoassay, functional (t-PA) for -chromogenic substrate and functional t-PAinhibitor (PAI) in 40 non-operable lung cancer patients (Table I) comprising 39 males and one female, aged 45 to 67 (average 59). The results are compared with those from a control group of 20 healthy male volun-ters aged 32 to 58 (average 48).Table II shows the results obtained (mean ± SD) for the parameters found to be significantly different to those of the control group. An increase is seen in the levels of FPA, functional t-PA and PAI in the lung cancer group. In the case of the extensive -lung tumor patients, FPAfpa and t-PA levels are significantly higher than for the group of locally advanced neoplasmas.The plasma of lung cancer patients therefore shows fibrinolytic alterations and an increase in thromboplastin activity.
