Abstract: Objective To investigate the clinical efficacy of three-dimensional conformal radiation therapy (3D-CRT) and intensity- modulated radiation therapy (IMRT) in the treatment of locally advanced non- small cell lung cancer (NSCLC) and the effect on serum vascular endothelial growth factor (VEGF) and peripheral blood immune factors. Method A cohort of 88 patients with locally advanced NSCLC was included in the study, who were stratified as group A (n=44) and group B (n=44) according to respective radiotherapy administered, patients in group A were given 3D-CRT (3~5 fields), with a total dose of 66 Gy; while group B were treated with static IMRT (5 fields), and the total radiation dose was 60 Gy. Both groups underwent chemotherapy with paclitaxel and carboplatin before radiation. The clinical efficacy and adverse reactions during radiation in both groups were observed, besides, the serum VEGF isoforms as well as immune factors in peripheral blood were compared between the two groups. Result There was no statistically significant difference in regard to the disease control rate and objective response rate between the two groups (P>0.05). In 180 d after treatment, the serum level of VEGFA, VEGFB, VEGFC, and the level of CD3+CD8+ T cell in peripheral blood were decreased, while the level of CD3+CD4+ T cell, CD4+/CD8+ T cell were increased compared with those before treatment in each group (P<0.05). During the same period, the level of serum VEGF subtypes (VEGFA, VEGFB, VEGFC) and peripheral blood immune factors (CD3+CD4+ T cell, CD3+CD8+ T cell, CD4+/CD8+ T cell) were similar between the two groups, with no significant difference observed (P>0.05). During the radiation, it was found that the incidence rate of radiation esophagitis and radiation pneumonitis were higher in group A than in group B (P<0.05). Conclusion 3D-CRT (66 Gy) and IMRT (60 Gy) can both improve the immune function in patients with locally advanced NSCLC, with decreased serum levels of VEGF, showing significant clinical efficacy, however, IMRT may be administered with lower dose, inducing less adverse reactions, which is more clinically applicable.
