T细胞核仁组成区嗜银蛋白对老年人肿瘤诊断的价值

The significance of AgNORs of peripheral T lymphocytes in the diagnosis of elderly cancer

目的 探讨老年肿瘤患者外周血T淋巴细胞核仁组成区嗜银蛋白的变化 ,及其与机体免疫关系。 方法 利用KL型肿瘤免疫图像分析系统检测 4 5例健康老年人 (对照组 )、36例老年炎症患者 (炎症疾病组 )、97例老年肿瘤患者 (肿瘤组 )和 30例老年肿瘤治愈患者 (肿瘤治愈组 )的外周血T淋巴细胞核仁组成区嗜银蛋白 ;应用流式细胞仪检测老年肿瘤组患者外周血T淋巴细胞表面分化抗原 (CD3、CD4、CD8)及自然杀伤细胞。 结果 与老年对照组〔(7 36± 0 76 )IS %〕及炎症疾病组〔(7 16± 1 0 4 )IS %〕相比 ,老年肿瘤组〔(5 39± 1 70 )IS %〕外周血T细胞嗜银蛋白降低 ,且差异有显著性 (P <0 0 1) ;转移性肿瘤患者嗜银蛋白下降更明显。 结论 外周血T淋巴细胞嗜银蛋白可作为老年人肿瘤的诊断和治疗监测指标。

Objective To investigate the diagnostic significance of argyrophilic nuclear organizer regions(AgNORs) of peripheral T lymphocytes in elderly cancer patients. Methods AgNORs was examined using KL tumor image analysis system in 45 cases of health control,36 cases of elderly inflammatory patients,97 cases of elderly cancer patients and 30 cases of elderly tumor-cured patients. CD3,CD4,CD8,CD4/8 and NK were detected by flow cytometer in cancer patients. Results Compared with normal controls,inflammation and tumor-cured patients,AgNORs was decreased extremely in elderly patients with cancer. Moreover,AgNORs was decreased in tumor metastasis status. Conclusions In analyzed elderly cancer patient cases,the expression of AgNORs is significantly decreased. The AgNORs may serve as a marker for judgment of clinical treatment and supervisor.
