恶性肿瘤的发生和发展与人体的免疫状态是密切相关的。人类恶性肿瘤是否存在肿瘤特异性抗原,机体抗癌的免疫反应以及癌细胞产生的各种免疫抑制因子,是肿瘤免疫领域中需要深入研究的几个重要问题。兹分别讨论于下。一、肿瘤的发生和发展与机体的免疫状态许多实验和临床资料表明,恶性肿瘤的发生、发展、结局、复发率和生存期都和机体的免疫状态密切相关的。
The occurrence and development of malignant tumors are closely related to the body’s immune status. The existence of tumor-specific antigens in human malignancies, the body’s immune response to cancer, and various immunosuppressive factors produced by cancer cells are several important issues that need to be further studied in the field of tumor immunity. It is discussed separately below. First, the occurrence and development of the tumor and the body’s immune status Many experimental and clinical data show that the occurrence, development, outcome, recurrence rate and survival of malignant tumors are closely related to the body’s immune status.
