很多资料证明癌的自然治愈暗示着宿主机体内存在着对癌的抵抗力的事实。另外尽管对恶性肿瘤的外科根治手术不能除去所有的肿瘤细胞,但事实上确有不少治愈的病例,且只要体内存在着一个恶性化了的体细胞,并不断增殖,就可使宿主丧命。作为这种矛盾现象的一种解释是 Everson 及 Cole 所谓的“患者自身的防御能力”。鉴于以上事实,增加宿主抵抗力的免疫疗法就成了癌症治疗上一个重要的方向。近年来在这个前提下研制 A lot of data prove that the natural cure of cancer implies the existence of host resistance to cancer in the host. In addition, although surgical resection of malignant tumors can not remove all the tumor cells, in fact, there are many cases of cure, and as long as the body has a malignant somatic cells, and continue to proliferate, you can make the host dead. One explanation for this paradox is Everson and Cole’s so-called “patient defenses.” In view of the above facts, immunotherapy to increase host resistance has become an important direction for the treatment of cancer. In recent years under the premise of the development
