对于中晚期恶性肿瘤的治疗,除手术治疗外,目前最常采用的疗法是化疗及放疗。但是,由于放疗及化疗对肿瘤细胞缺乏选择性杀灭作用,且有不敏感的肿瘤细胞群体存在,通常疗效不佳。近几年来,由于对肿瘤具有明显选择性的单克隆抗体的出现,以及新型交联剂及交联方法的研制成功,使得肿瘤导向治疗的设想逐渐成为现实,这方面的研究正在世界范围内不断兴起并深入发展。表现在如下几个方面: For the treatment of advanced and advanced malignant tumors, in addition to surgical treatment, the most commonly used therapy at present is chemotherapy and radiotherapy. However, due to the lack of selective killing of tumor cells by radiotherapy and chemotherapy, and the existence of insensitive tumor cell populations, the efficacy is usually poor. In recent years, due to the emergence of monoclonal antibodies with clearly selective tumors, and the successful development of novel cross-linking agents and cross-linking methods, the concept of tumor-directed therapy has gradually become a reality. Research in this area is continuing worldwide. Rise and deepen development. Performance in the following areas:
