摘要：

Objective: To discuss the effect of intensity modulated radiation therapy combined with paclitaxel + endostar chemotherapy on serum malignant molecule levels in patients with locally advanced non-small cell lung cancer. Methods: Patients with locally advanced NSCLC who were treated in the hospital between February 2015 and January 2017 were collected and divided into control group (n=59) and research group (n=59) by random number table. Control group received the routine paclitaxel + endostar chemotherapy after the operation, and research group underwent intensity modulated radiation therapy combined with paclitaxel +endostar chemotherapy after the operation. The differences in serum levels of NSCLC-related tumor markers and angiogenesis indexes were compared between the two groups before and after treatment. Results: Before treatment, the differences in serum levels of NSCLC-related tumor markers and angiogenesis indexes were not statistically significant between the two groups. After treatment, serum TK1, CYFRA21-1, Pro-GRP, CEA, CA125 and SCC-Ag levels of research group were lower than those of control group; serum EGFR, COX-2, VEGF, HIF-1 and MMP-2 levels of research group were lower than those of control group. Conclusion:Postoperative intensity modulated radiation therapy combined with paclitaxel + endostar chemotherapy can effectively reduce the serum malignant molecule levels and optimize the illness in patients with local advanced NSCLC.
