近数年来对于免疫因素在宿主对肿瘤防御作用中的重要作用,有了一些了解。人体的新生物含有诱导宿主的体液和细胞产生免疫反应的抗原,某些临床观察亦表明人体对肿瘤发展的抗御能力的重要性。肾上腺瘤,黑色素瘤,和绒毛膜癌是较常见的自行缓解的肿瘤。抑制免疫反应将增加发生癌的危险:先天性免疫缺陷综合症的儿童在早年即有很高的癌发病率,接受免疫抑制剂的器官
In recent years, there has been some understanding of the important role of immune factors in host defense against tumors. New human organisms contain antigens that induce humoral and cellular immune responses in the host. Some clinical observations also indicate the importance of the body’s ability to resist tumor development. Adrenal tumors, melanoma, and choriocarcinoma are the more common self-resolving tumors. Inhibiting the immune response will increase the risk of developing cancer: Children with congenital immunodeficiency syndrome have a high incidence of cancer in early years, and organs that receive immunosuppressive drugs
