免疫治疗肿瘤的理论根据,就是基于许多动物和人体肿瘤都具有特异性移植抗原。但通常这些抗原都很弱,因此单纯用肿瘤细胞疫苗的治疗很不理想,它所诱导的体内免疫抗癌作用极为轻微,常不足以阻止癌细胞的无休止的狂乱生长,最后导致宿主死亡。 The theoretical basis for immunotherapy of tumors is based on the fact that many animal and human tumors have specific transplant antigens. However, these antigens are usually very weak. Therefore, treatment with a tumor cell vaccine alone is not ideal. The anti-cancer effect induced by in vivo immunity is extremely slight, and it is often insufficient to prevent the endless and uncontrolled growth of cancer cells, and eventually lead to the death of the host.
