摘要: 目的 探讨晚期非小细胞肺癌(NSCLC)化疗前、后血清细胞角蛋白19片段(CYFRA21-1)变化在疗效监测中的价值。 方法 用化学发光免疫分析法对66例晚期NSCLC患者化疗前、后和30名健康对照者血清CYFRA21-1含量进行测定,分析不同疗效患者血清CYFRA21-1含量变化差异。 结果 在进行一线药物化疗前,NSCLC患者血清CYFRA21-1水平明显高于健康对照组(P<0.05),肺鳞癌组患者水平高于肺腺癌组(P<0.05);一线化疗后,缓解组较化疗前CYFRA21-1水平明显下降(P<0.05),无效组和进展组明显高于治疗前(P<0.05)。 结论 血清CYFRA21-1在监测肺癌化疗患者病情、判断化疗效果中具有确切的价值。

Abstract: Objective To investigate the significance of serum cytokeratin 19 fragment 21-1(CYFRA21-1) changes before and after chemotherapy in monitoring the therapeutic efficacy of advanced stage non small cell lung cancer(NSCLC).   Methods The serum CYFRA21-1 levels of 66 patients with advanced stage NSCLC before and after chemotherapy and 30 healthy controls were measured by chemiluminescence immunoassay,and the change differences of serum CYFRA21-1 in the patients with different therapeutic efficacy were analyzed. Results Compared to those in the controls,serum CYFRA21-1 levels were significantly higher than those in patients before the first-line chemotherapy(P<0.05). Furthermore,the serum CYFRA21-1 levels in patients with squamous cell lung carcinoma were higher than those with pulmonary adenocarcinoma(P<0.05). Compared to those before chemotherapy,serum CYFRA21-1 levels significantly decreased in release group after the first-line chemotherapy(P<0.05). However,compared to those before chemotherapy,serum CYFRA21-1 levels significantly decreased in invalid group and progress group(P<0.05). Conclusions Serum CYFRA21-1 is exactly valuable in monitoring the pathogenetic condition and judging the chemotherapy efficacy of the patients with lung cancer.
