摘要 目的:检测骨肉瘤细胞中一氧化氮合酶iNO S的表达,研究其与骨肉瘤临床特征和血管内皮生长因子(VEGF)表达的相关性,探讨iNO S在骨肉瘤发生发展及转移中的作用及机制。方法:采集骨肉瘤标本及其病例资料,采用免疫组织化学技术检测48例骨肉瘤标本iNO S和VEGF的表达,统计分析iNO S与VEGF在骨肉瘤组织中表达的相关性和iNO S在骨肉瘤表达与病例临床特征之间的相关性。结果:iNO S和VEGF在肿瘤组织中的阳性表达率明显高于对照组织(P<0.01),iNO S的表达与病理分化程度、诊断时骨肉瘤有否转移密切相关,而与骨肉瘤的发病年龄、性别、肿瘤大小、原发部位、D ah lin病理分型均无关。结论:iNO在骨肉瘤中的表达可能参与肿瘤的发生发展和转移,有可能成为评价骨肉瘤转移和预后的分子指标和辅助治疗骨肉瘤的新靶点。
