放射线治疗和抗癌药物一样是属于免疫抑制剂。它能影响机体的免疫功能状态,但影响的程度及在放射治疗过程中那个阶段影响最大的问题,文献报导还不多。我们为了要研究鼻咽癌、肺癌放射治疗过程中免疫功能的动态变化,乃于1974年7月至1974年底期间,在病人放射治疗的前、中、结束三个时期进行了体内及体外细胞免疫的测定,现将结果报告如下。 Radiotherapy is like immunosuppressive drugs like anticancer drugs. It can affect the body’s immune function status, but the extent of the impact and the most influential issues during that period of radiation therapy are not reported in the literature. In order to study the dynamic changes of immune function during radiotherapy of nasopharyngeal carcinoma and lung cancer, we performed in vivo and in vitro cellular immunity during the period from July 1974 to the end of 1974 during the pre-, mid-term, and end-stage of patient radiation therapy. The determination is now reported as follows.
