Abstract:Objective: To explore the efficacy and safety of conformal intensity-modulated radiotherapy combined with targeted therapy in the treatment of brain metastases from lung cancer. Methods: 82 patients with brain metastases from lung cancer admitted to hospital from January 2012 to June 2017 were selected and divided into control group and observation group according to the random number table method, with 41 cases in each group. Control group was given conformal intensity-modulated radiotherapy combined with chemotherapy, and observation group was given conformal intensity-modulated radiotherapy combined with targeted therapy. The serum levels of tumor indexes factors were detected by ELISA. The serum levels of tumor indexes factors, efficacy, adverse reactions and 1-year survival rate were observed and compared between the two groups. Results: The total effective rate in observation group was significantly higher than that in control group (92.68% vs 70.73%) (χ2=6.609, P=0.010). The serum levels of TNF-α, NSE, SCC-Ag and CEA in observation group were significantly lower than those in control group (t=5.122, 13.013, 13.416, 22.857, P=0.000, 0.000, 0.000, 0.000). There was no significant difference in the incidence rate of adverse reactions between the two groups after treatment (P>0.05), and they were tolerated. The 1-year PFSand 1-year OS were 63.42% and 68.29% in observation group, which were significantly higher than those in control group with 36.56% and 46.34% (Log-rank χ2=6.874, 4.797, P=0.008, 0.029). Conclusions: Intensity modulated radiation therapy (IMRT) combined with targeted therapy can be used for symptomatic patients with brain metastases from lung cancer. The clinical efficacy is significantly better than that of radiotherapy and chemotherapy, and the side effects are tolerable.
