Tissue inhibitor of metalloproteinases (TIMP1) regulates not only extracellular matrix catabolism but the major effect in tumor tissue is promotion of cell growth and anti-apoptotic activity. The aim of our study was to evaluate plasma TIMP I levels and tissue TIMP1 mRNA expression as prognostic markers in NSCLC patients. Patients and Methods: We studied a group of 108 patients with NSCLC who had undergone lung surgery. Estimation of TIMP1 mRNA was performed by quantitative polymerase chain reaction (qPCR) and estimation of plasma TIMP I protein using enzyme-linked immunosorbent assay (ELISA). Results: There was shorter disease-free interval (DFI) for NSCLC patients at stage II, with a higher expression of TIMP1 mRNA in tumor tissue (p=0.0246). We recorded a relationship between tumor tissue TIMP1 mRNA expression and DFI in squamous cell carcinoma (SCC) (p=0.0117). Shorter overall survival was found in patients at stages IIIa+IIIb+IV, with a higher expression of TIMP1 mRNA (p=0.0389). We found differences in plasma TIMP1 levels between patients with SCC and those with adenocarcinoma (p=0.0491). Conclusion: A higher tissue level of TIMP1 mRNA is related to an adverse prognosis of patients. However, our results did not show any relation of TIMP1 protein in blood plasma to prognosis.
