Abstract

目的 探讨血管内皮生长因子(VEGF)对恶性腹水的诊断价值及其在恶性腹水形成中的作用.方法收集各种类型腹水及腹腔液,采用ELISA法检测VEGF水平.结果癌性腹水组VEGF水平为(640.7±264.8)pg/ml,明显高于肝硬变腹水组、结核性腹水组及良、恶性疾病不伴腹水患者腹腔液组(P<0.01),而后4组间比较VEGF水平则无明显差异(P>0.05).不同组织来源恶性腹水中卵巢癌组VEGF水平为(866.3±208.5)pg/ml,高于胃癌组(P<0.01)和结肠癌组(P<0.01);胃癌组VEGF水平高于结肠癌组,但差异无显著性(P>0.05).以肝硬变腹水作为对照组,以其VEGF含量均值上限118.96pg/ml为阳性界值时,诊断恶性腹水的敏感性为91.3%,特异性为88.9%.结论VEGF对良、恶性腹水的鉴别诊断有重要价值,它可能在恶性腹水的形成中起重要作用。
