癌症的治疗手段随医学、药学、免疫学、分子生物学等学科的发展而不断完善。当前,除手术、放疗、化学药物治疗的综合应用外,在癌症治疗中,生物反应调节剂的应用被称为第四种治疗模式。随着肿瘤病因学研究的深入,认识到肿瘤能逃避宿主的免疫监视作用而得到发生、发展的原因之一,是由于肿瘤患者的免疫功能防御系统对肿瘤细胞失去调控。如何恢复并提高机体的免疫功能,成为肿瘤治疗中的重要环节之一。在肿瘤治疗中一般将抗肿瘤药 The treatment of cancer has been continuously improved along with the development of medicine, pharmacy, immunology, and molecular biology. Currently, in addition to the combined use of surgery, radiotherapy, and chemotherapy, the use of biological response modifiers is called the fourth treatment model in cancer treatment. With the deepening of tumor etiology studies, one of the reasons for the occurrence and development of tumors that can evade the immune surveillance of the host is the loss of regulation of tumor cells by the immune function defense system of tumor patients. How to restore and improve the body’s immune function has become an important part of cancer treatment. Antitumor drugs are generally used in tumor therapy
