中文摘要:

目的回顾性研究晚期非小细胞肺癌患者放疗前后血清CEA、CYFAR21-1、SCC、CA125的水平变化,探讨血清肿瘤标志物的改变及与放疗近期疗效的关系。方法常规检查205例经确诊的晚期非小细胞肺癌患者放疗前、后血清CEA、CYFAR21-1、SCC、CA125等肿瘤标志物的水平(应用电化学发光法), 同时评估放疗的近期疗效,分析肿瘤标志物的变化及与近期疗效的关系。结果 205例患者放疗后近期有效113例,总有效率为55.1%。此113例患者放疗后血清CEA、CYFAR21-1、SCC、CA125水平均较放疗前发生了明显下降(t=3.224, 2.896, 3.137, 3.219, P<0.05),其中Ⅲ期及Ⅳ期患者血清肿瘤标志物CEA、CYFAR21-1、SCC、CA125放疗后与放疗前比较,差异均有统计学意义(Ⅲ期:t=2.484, 2.445, 2.148, 2.109, P<0.05;Ⅳ期:t=2.072, 2.857, 2.277, 2.436, P<0.05);而放疗后近期非有效的92例患者中,放疗后血清肿瘤标志物较放疗前明显上升(t=2.224, 2.005, 2.261, 2.545, P<0.05)。放疗后肿瘤标志物降低组的近期疗效明显好于肿瘤标志物升高组,差异有统计学意义(χ²=80.001, P<0.01)结论血清肿瘤标志物CEA、CYFAR21-1、SCC、CA125水平或可用于晚期非小细胞肺癌患者放疗后的近期疗效评估。

英文摘要:

Objective To investigate the change of the serum levels of CEA, CYFAR21-1, SCC, CA125 in advanced non-small cell lung cancer patients before and after radiotherapy retrospectively and to explore the relationship between the change of serum tumor markers and the short-term efficacy of radiotherapy.Methods The serum levels of CEA, CYFAR21-1, SCC, CA125 in 205 cases with advanced non-small cell lung cancer were detected( by electro-chemiluminescence immunoassay method) before and after radiotherapy,and the short-term efficacy of radiotherapy was assessed (RECIST 1.1 edition) at the same time. The changes in tumor markers and the short-term efficacy were analyzed. Results Totally 113 patients achieved response of short-term efficacy after radiotherapy, and the effective rate of the short-term efficacy was 55.1%. Among these 113 patients, the serum levels of tumor markers decreased significantly after radiotherapy(t=3.224, 2.896, 3.137, 3.219, P<0.05). The serum levels of tumor markers in patients with stage Ⅲ and Ⅳ decreased after radiotherapy (t=2.484, 2.445, 2.148, 2.109, P<0.05;t=2.072, 2.857, 2.277, 2.436, P<0.05). Among 92 patients who did not achieve response of short-term efficacy, the serum level of tumor markers increased significantly after radiotherapy(t=2.224, 2.005, 2.261, 2.545, P<0.05).For the patient who achieved response of radiotherapy with tumor markers decreased,the short-term efficacy was significantly better than the group of which tumor maker increased (χ²=80.001, P<0.01). Conclusions The serum levels of CEA, CYFAR21-1, SCC, CA125 can be used for assessment of short-term efficacy after radiotherapy in advanced non-small cell lung cancer patients.
