摘要: 目的 探讨胰岛素样生长因子-1(IGF-1)对非小细胞肺癌的诊断意义。方法 应用免疫放射法定量检测90例经病理证实的非小细胞肺癌患者及20名健康对照组血清IGF-1水平。结果 非小细胞肺癌组血清IGF-1水平[(122.6±20.3)ng/mL]明显高于健康对照组[(82.7±20.5)ng/mL](P<0.05);有腋窝淋巴结转移患者的IGF-1水平[(133.2±21.3)ng/mL]明显高于未转移患者[(108.2±15.1)ng/mL](P<0.05);临床TNM分期Ⅲ~Ⅳ期肺癌患者血清IGF-1水平[(129.3±20.1)ng/mL]明显高于I~II期患者[(115.2±15.2)ng/mL](P<0.05);肺癌组IGF-1与癌胚抗原(CEA)、细胞角蛋白19片段(CYERA21-1)浓度呈正相关(r=0.58,r=0.49,P均<0.01)。结论 IGF-1在非小细胞肺癌患者外周血中高表达与肺癌的发生、发展及转移有关,在肺癌的早期诊断中具有应用价值。

Abstract: Objective To study the sigificance of insulin-like growth factor 1(IGF-1)in the diagnosis of non-small cell lung cancer.  Methods The serum IGF-1 levels in 90 patients with non-small cell lung cancer and 20 healthy controls were determined by immunoradiometric quantitation assay.  Results The levels of serum IGF-1 were significantly higher in non-small cell lung cancer group than in healthy control group [(122.6±20.3)ng/mL and(82.7±20.5)ng/mL,P<0.05]. The levels of IGF-1 in all patients with lymphatic metastasis [(133.2±21.3)ng/mL] were higher than those in patients without lymphatic metastasis [(108.2±15.1)ng/mL,P<0.05]. The levels of IGF-1 in patients at Phase Ⅲ-Ⅳ[(129.3±20.1)ng/mL] were higher than those at Phase Ⅰ-Ⅱ [(115.2±15.2)ng/mL,P<0.05]. In non-small cell lung cancer group,the levels of IGF-1 had a significantly positive correlation with carcinoembryonic antigen(CEA)and cytokeratin-19-fragment(CYERA21-1)respectively(r=0.58 and r=0.49,P<0.01).  Conclusions High level of serum IGF-1 may have a significant correlation with the pathogenesis,development and metastasis of non-small cell lung cancer,and IGF-1 may have an application significance for the early diagnosis of lung cancer.
