肿瘤的病因及发病机理至今尚未阐明。大量的实验及临床研究证实,机体的免疫状态与肿瘤的发生、发展密切相关。对肿瘤的治疗,70年代初,由于单克隆抗体制备技术的建立及Ｔ细胞生长因子(Ｔｃｅｌｌｇｒｏｗｔｈｆａｃｔｏｒ,ＴＣＧＦ)的发现,以及免疫监视学说的提出,使免疫监视功? The etiology and pathogenesis of tumors have not yet been elucidated. A large number of experiments and clinical studies have confirmed that the body’s immune status is closely related to the occurrence and development of tumors. For the treatment of tumors, in the early 1970s, due to the establishment of monoclonal antibody preparation technology and the discovery of T cell growth factor (TCGF), as well as the concept of immunosurveillance, immune surveillance was performed.
