用双抗体夹心ＥＬＩＳＡ法检测４９例鼻咽癌患者放疗前后血清可溶性白细胞介素－２受体（ｓＩＬ－２Ｒ）水平。结果显示，鼻咽癌放疗前血清ｓＩＬ－２Ｒ水平不同临床分期及转移性淋巴结大小无显著差异。放疗后血清ｓＩＬ－２Ｒ水平较放疗前显著降低，说明检测血清ｓＩＬ－２Ｒ可作为观察鼻咽癌治疗前后免疫状况的一种方法，是否可以作为衡量近远期疗效的指标有待进一步研究
Serum soluble interleukin-2 receptor (sIL-2R) levels were measured in 49 patients with nasopharyngeal carcinoma before and after radiotherapy with double antibody sandwich ELISA. The results showed that the level of serum sIL-2R in nasopharyngeal carcinoma before radiotherapy with different clinical stages and metastatic lymph node size was no significant difference. Serum sIL-2R level after radiotherapy was significantly lower than before radiotherapy, indicating that serum sIL-2R detection can be used as a way to observe the immune status of nasopharyngeal carcinoma before and after treatment, whether it can be used as a measure of short-term efficacy of the index needs further study
