癌症患者如果能早期发现,治愈率可达80%,这是世界卫生组织最新的权威性结论。但要早期诊断癌症却相当困难和复杂。近来,国内多家医院开展“一滴血验癌”新技术,每次只需抽取人体0.5ml的血液,短时间内就可判断出12项肿瘤标志物的浓度。也就是说,检查肿瘤将像常规验血一样方便、快捷。“一滴血验癌”其实是一种生物芯片技术,是当今生命科学领域发展最快的技术之一。这一技术通过对12种临床常用的肿瘤标志物含量的分析来检测肿瘤的有无。就单项的肿瘤标志物来说,它们在临床上已应用多年,并在临床诊疗中被证明是有效的标志物,得到医学界的认可。作为多种肿瘤标志物联合检测一种肿瘤,是这些年来临床与实验室一直在寻求的诊断模式,因为这可以提高对单种肿瘤诊断的敏感性和特异性。蛋白芯片技术正是在这方面有 If cancer patients can be found early, the cure rate can reach 80%, which is the latest authoritative conclusion of the World Health Organization. However, it is difficult and complicated to diagnose cancer early. Recently, a number of hospitals in China have developed a new technique called “a drop of blood for cancer screening.” Each time, only 0.5 ml of blood is taken from the human body. The concentration of 12 tumor markers can be determined within a short time. In other words, the inspection of the tumor will be as convenient and quick as regular blood tests. “A blood test” is actually a kind of biochip technology and it is one of the fastest growing technologies in the life sciences. This technique detects the presence or absence of tumors by analyzing the content of 12 clinically common tumor markers. For single tumor markers, they have been clinically used for many years, and have been proven to be effective markers in clinical diagnosis and treatment, and have been recognized by the medical community. The combined detection of multiple tumor markers as a tumor is a diagnostic model that has been pursued clinically and in the laboratory for many years because it can increase the sensitivity and specificity of single tumor diagnosis. Protein chip technology is exactly in this area
