MMP2 and lung neoplasm: In contrast, we observed lower concentrations of MMP-2 in patients with other lung neoplasms and the -735CC genotype (x ̄ = 138.05 ng/mL), than in patients with other lung neoplasms and the -735CT genotype (x ̄ = 164.48 ng/mL) at the limit of statistical significance (p = 0.060294).
