1、临床医学论文-评价胸腔积液端粒酶活性检测对胸腔积液性质的鉴别诊断价値作者:吴瑞景'关万宁'方万强'谢国均'黄永强'甄碧月冃的探讨胸腔积液端粒酶活性检测方法在诊断恶性胸腔积液的临床价値。方法对我院自2002年9月〜2004年11月问收诊的108例已确诊的胸腔积液病例,分良性胸腔积液组和恶性胸腔积液组,分别对每一病例检测胸腔积液端粒酶活性、CEA、OTRA21-1和胸腔积液细胞学检查,比较以上各种检查方法对恶性胸腔积液诊断的特异性和敏感性,观察数据采用t检验、力2检验、相关分析。结果胸腔积液CEA检测诊断恶性胸腔积液敏感性为62.5%特异性为91.1
2、%^准确率为76.9%。胸腔积液CYFRA21・1检测诊断恶性胸腔积液敏感性为48.1%,特异性为96.4%,准确率为73.2%o细胞学检测诊断恶性胸腔积液敏感性为34.6%,特异性为100%,准确率为68.5%°胸腔积液端粒酶活性检测诊断恶性胸腔积液敏感性为88・0%,特异性为89.3%准确率为88.9%°结论胸腔积液端粒酚活性检测对诊断恶性胸腔积液有较高敏感性和特异性,其准确性优于胸腔积液CEA、CRFRA21J和细胞学检测等方法,是一种较理想的生物检测指标,値得临床进一步硏究和推广应用。【关键词】恶性胸腔积液;端粒酶;诊断;鉴别诊断Clin
