Abstract Although fibrinolysis has been implicated in the progression and metastasis of lung cancer, no detailed study has been carried out on components measured in samples from both plasma and tumour. This study thus provides the first comprehensive data obtained from 166 patients diagnosed with non-small cell lung carcinoma. Plasma samples were obtained at diagnosis and tumour samples during surgical resection. Appropriate control samples were obtained from normal subjects and patients with chronic obstructive airways disease (plasma) and from organ donors (normal lung tissue). Assays were performed on plasma and tissue extracts for tissue plasminogen activator, urokinase-like activator and plasminogen activator inhibitor (activity and antigen in all cases), together with plasmin-antiplasmin complex, soluble fibrin, D-dimer and thrombin-antithrombin complex. Levels of D-dimer, thrombin-antithrombin complex and plasmin-antiplasmin complex were all significantly higher in plasma from patients, whereas urokinase-like activator activity was reduced. Only two parameters were significantly altered in both the core and periphery of tumour tissue: levels of D-dimer were increased and tissue-type plasminogen activator activity was reduced. Interestingly, significant differences in levels of other fibrinolytic parameters were detected in the core and periphery of tumours. Significant activation of fibrinolysis was indicated in patients, although the origin of this could not be related consistently to changes in levels of plasminogen activator and inhibitor.
