摘要 目的研究前列腺癌(Pca)患者的血清胰岛素样生长因子-1(insulin-like growth factor-1,IGF-1)水平,以了解IGF-1在Pca诊断中的意义。方法应用免疫放射分析法(IRMA)测定30例前列腺癌患者血清胰岛素样生长因子-1水平,并以30例健康组和30例良性前列腺增生症(BPH)组患者作对照。结果前列腺癌组血清IGF-1含量显著上升(148±49.6)μg/L,与BPH(91.0±32.8)μg/L及健康组(105±25.6)μg/L差异有显著性(均P<0.01)。BPH组血清IGF-1含量与健康组差异无显著性(P>0.05);前列腺癌组各期IGF-1含量比较差异无显著性(P>0.05);IGF-1与BPH无关,其水平升高增加前列腺癌的危险性,与健康组比较,高IGF-1水平患者前列腺癌的相对危险度(OR)为11.23,95%CI3.09~40.7,前列腺癌患者与健康组之间有统计学意义(P<0.01)。结论IGF-1可能增加PCa的危险性。检测血清IGF-1水平对提高Pca的诊断率可能有帮助。
