近年来,各种肿瘤的导向研究日益增多,主要包括二个方面:导向诊断与导向治疗。一、原发性肝癌(简称肝癌)的导向诊断:为免疫技术和核医学的诊断方法,称之为放射免疫探测法或放射免疫显像法,又称之为阳性扫描。其原理是利用抗体和相应肿瘤靶抗原的特异结合力,先用标记法将核素交联活性抗体,经标记后的活性抗体携带核素在肿瘤靶抗原的部位积聚。由于具有靶抗原的肿瘤摄取核素标记的相应抗体较正常周围组织为多,因此二者之
In recent years, the research on the orientation of various types of tumors has been increasing, mainly including two aspects: oriented diagnosis and targeted therapy. First, the direction of diagnosis of primary liver cancer (referred to as liver cancer): The diagnosis of immune technology and nuclear medicine, called radioimmunoassay or radioimmunodetection, also known as positive scan. The principle is to use the specific binding force of the antibody and the corresponding tumor target antigen, first cross-link the active antibody by the labeling method, and accumulate the labeled active antibody-carrying radionuclide at the site of the tumor target antigen. Since the corresponding antibodies with tumor target radionuclides labeled with target antigen are more than normal surrounding tissues, both
