作者对62例肺癌患者进行红细胞免疫功能及T淋巴细胞亚群测定，并与20例正常人对照。结果显示：肺癌组红细胞膜C3b受体活性（RBC－C3bRR）、CD3+、CD4+、CD4+／CD8+比值均低于正常人（P＜0．05～0．01），红细胞膜的吸附免疫复合物（RBC－ICR）、CD8+均高于正常人（P＜0．05～0．01），因此认为红细胞免疫及T淋巴细胞亚群测定对肺癌的诊断、治疗及病情预后估计有一定价值。
The authors performed erythrocyte immune function and T lymphocyte subsets measurements in 62 patients with lung cancer, and compared with 20 normal controls. The results showed that the RBC membrane C3b receptor activity (RBC-C3bRR), CD3+, CD4+ and CD4+/CD8+ ratios in the lung cancer group were lower than those in normal controls (P<0.05 to 0.01), and red blood cell membranes were adsorbed on immune complexes ( RBC-ICR and CD8+ were all higher than normal subjects (P<0.05-0.01). Therefore, it is believed that the detection of red blood cell immunity and T-lymphocyte subsets has some value in the diagnosis, treatment and prognosis of lung cancer.
