Effect of Pemetrexed combined with cis-platinum chemotherapy on matrix metalloproteinase VEGF, NK cells and immune function in patients with non-squamous non-small cell lung cancer

摘要

Objective:To explore effect of Pemetrexed combined with cis-platinum chemotherapy on matrix metalloproteinase (MMPs), vascular esandothelial growth factor (VEGF), NK cells and immune function in patients with non-squamous non-small cell lung cancer.Method:A total of86 cases of non-squamous non-small cell lung cancer patients were divided into control group (n=44) and observation group (n=42), control group was given docetaxel combined cis-platinum chemotherapy, pemetrexed combined cis-platinum chemotherapy, was applied for observation group. Compared MMP-2, MMP-9, VEGF, NK cells and immune function level before and after treatment in both groups.Results: MMP-2, MMP-9, VEGF, NK cells, CD3+, CD4+, CD8+, CD4+/CD8+ level in both groups before treatment was no significant difference. After treatment, MMP-2, MMP-9, VEGF, CD8+level in both groups was significant lower than before treatment intra-group, and observation was lower than control group, there was significant difference. After treatment, NK cells, CD3+, CD4+, CD8+, CD4+/CD8+ level in both groups was increased dramatically than before treatment of intra-group, moreover, NK cells, CD3+, CD4+, CD8+, CD4+/CD8+level in observation group after treatment was obvious higher than in control group after treatment, there was significant difference.Conclusion:Pemetrexed combined with cis-platinum chemotherapy for non-squamous non-small cell lung cancer could effectively decrease serum MMPs, VEGF level and increase NK cell level, regulate immune function, with definite clinical significance.
