日本开发新技术可利用唾液筛查癌症

日本研究人员日前报告说，他们开发出一种新技术，只需分析人体唾液，即可筛查口腔癌、乳腺癌和胰腺癌等癌症，而且准确度很高。! t/ B: B7 f, \/ p

　　日本庆应义塾大学在新闻公报中说，癌细胞比正常细胞增殖迅速，受其影响，唾液中的数百种物质也会出现浓度变化。他们通过比对癌症较早期患者与正常人的唾液，发现有54种氨基酸的浓度存在重大差异。

　　研究人员进而对这54种氨基酸进行分析，发现可以利用它们准确筛查多种癌症，其中，口腔癌的筛查准确率为80%，乳腺癌为95%，胰腺癌为99%。- f7 c, g' ~, v" Y, |* z. n$ L

　　与血液检查筛查癌症相比，唾液检查更为便捷，且不会增加身体负担。下一步，研究人员还准备开发成本更低、更易操作的唾液分析仪器，以早日达到实用化水平。

Japan's Keio University and University of California, Los Angeles, have developed the technology with which they detected high probabilities of pancreatic cancer, breast cancer and oral cancer.
