采用计算机辅助图像分析系统对476例肿瘤与非肿瘤患者外周血淋巴细胞进行AgNOR图像分析。结果说明，肿瘤组GA／NA值低于非肿瘤（P＜0．01）；呼吸系统和消化系统肿瘤组GA／NA值也低于非肿瘤组（P＜0．01）。认为血GA／NA值可作为鉴别肿瘤与非肿瘤的指标。
The computer-assisted image analysis system was used to analyze the AgNOR images of peripheral blood lymphocytes in 476 tumor and non-tumor patients. The results showed that GA/NA values in the tumor group were lower than those in the non-tumor group (P<0.01); GA/NA values in the respiratory and digestive system tumor groups were also lower than those in the non-tumor group (P<0.01). Blood GA/NA values can be considered as indicators for identifying tumors and non-tumors.
