Methods Patients with advanced NSCLC were studied. The patients in the control group received chemotherapy with paclitaxel combined with cisplatin. Patients in the combination group received intravenous infusion of endostar on the basis of treatment of patients in the control group. 21 days was a cycle, and all patients were treated for 2 cycles. Fasting venous blood 3mL of all patients before and after treatment was collected, and CEA and saccharide antigen (CA50) were detected by radioimmunoassay. Vascular endothelial growth factor (VEGF), neuron-specific enolase (NSE), serum matrix metalloproteinase (MMP-2, MMP-9), high-mobility family protein at-hook 2 (HMGA 2) and high-mobility family protein B 1 (HMGB 1) were detected by ELISA. Results There were no significant differences in serum CA50, CEA, VEGF, NSE, mmp-2, mmp-9, HMGB 1, and HMGA 2 between the two groups before treatment (P>0.05). After two courses of chemotherapy, CA50, CEA, VEGF, NSE, MMP-2, MMP-9, HMGB 1, and HMGA 2 in the combination group and control group were significantly lower than before treatment (P<0.05), and the combination group was significantly lower than the control group (P<0.05). Conclusion Endostar combined with paclitaxel can enhance the chemotherapy effect of NSCLC patients, reduce the level of serum tumor markers, neuronal specific enolase and vascular endothelial growth factor, and inhibit the proliferation and migration of tumor cells.展开更多
