125名头颈癌在手术和/或放疗前,取周围血液进行了淋巴细胞亚群及其体外免疫功能的测定。患者随访4年,结果有49人复发。复发者治疗前的淋巴细胞生成白细胞介素-2(IL-2)的水平(1.51±0.2)明显高于无复发者(1.15±0.2)和正常人(1.06±0.3)。对丝裂素的反应也有增加的倾向。若根据 IL-2水平高低分析28个月左右达一稳定水平的存活率,发现 IL-2水平高(≥1.0)的患者为28％,IL-2水平 125 cases of head and neck cancer before surgery and / or radiotherapy, take the surrounding blood lymphocyte subsets and in vitro immune function determination. Patients were followed up for 4 years, resulting in 49 recurrences. The level of interleukin-2 (IL-2) production by lymphocytes in pre-treatment relapse patients was significantly higher than that in non-relapse patients (1.15 ± 0.2) and normal subjects (1.06 ± 0.3) (1.51 ± 0.2). The response to mitogen also tends to increase. According to the level of IL-2 analysis of 28 months or so reached a stable level of survival and found that IL-2 levels were high (≥ 1.0), 28% of patients, IL-2 levels
