MMP9 and non-small cell lung carcinoma: The analysis of one-year survival in NSCLC patients showed no differences in the expression of the examined genes in the tumor tissue based on the one-year survival of the patients (TIMP1 (p = 0.7463); MMP2 (p = 0.8729); MMP9 (p = 0.7338)) and in the blood taken before surgical resection (TIMP1 (p = 0.5565); MMP2 (p = 0.1253); MMP9 (p = 0.304)).
