晚期非小细胞肺癌外周血血管内皮生长因子检测及其临床意义

目的 探讨晚期非小细胞肺癌(NSCLC)患者血清中血管内皮生长因子(sVEGF)水平及评价其临床意义.方法 应用酶联免疫吸附法(ELISA)测定sVEGF在96例晚期NSCLC患者血清中的表达,分别给含顺铂的联合化疗方案2～4个周期后再测定其sVEGF水平;同时检测50例健康体检者的sVEGF水平.结果 肺癌患者sVEGF含量明显高于健康对照组(P＜0.01);腺癌sVEGF水平与鳞癌相比差异无统计学意义(P＞0.05);Ⅲ、Ⅳ期患者sVEGF水平相比差异无统计学意义(P＞0.05);所有缓解病例化疗后sVEGF水平均显著下降(P＜0.05).结论 晚期NSCLC患者sVEGF水平与其诊断及治疗效果密切相关.

Elevated serum level of VEGF in advanced non-small cell lung cancer and its clinical significance

Objective To study the level of serum vascular endothelial growth factor(sVEGF)in advanced non-small cell lung cancer(NSCLC) and its clinical significance.Methods Serum level of VEGF was detected by ELISA method in 96 patients with advanced NSCLC.sVEGF level was analyzed after giving 2-4 cycles of cisplatin-based chemotherapy.At the same time,serum level of VEGF in 50 healthy controls was detected.Results The level of sVEGF was significantly higher in patient with lung cancer than in control group (P＜0.01).No statistical significant defference was observed between sVEGF level of stage Ⅲ and Ⅳ NSCLC patients,the patients with squamocellular lung cancer and adenocarcinoma(P＞0.05);Descended sVEGF level was found in the patients with response to chemotherapy(P＜0.05).Conclusion sVEGF can be used to evaluate chemotherapy response and diagnoses in the patients with advanced NSCLC.
