项目摘要
(Clinical evaluation) As for the retention index (delayed uptake / early uptake), 99m-Tc-MIBI showed the retention index of under 1 (mean ± SD = 0.853 ± 0.067) in malignant tumor, indicating a tendency of decreasing in the delayed uptake. On the other hand, the retention indexes of 201-TlCl scintigraphy were classified into three groups according to histopathological types of tumor ; 0.81 ± 0.06 in benign tumors, 1.01 ± 0.10 in well differentiated malignant tumors, 1.09 ± 0.13 in moderately differentiated tumors, and 1.24 ± 0.14 in poorly differentiated tumors. Thus, the mean retention indexes were under 1 in benign tumor, but over 1 in malignant tumor. The higher the histopathological grade was, the larger the retention index became.(Accumulation mechanism) As for the relationship between P-gp expression (score 0, 1 and 2) and histopathological type of tumor, the scores (mean ± SD) = 0.75 ± 0.19 in benign tumors, 0.71 ± 0.36 in well differentiated tumor, 0.83 ± 0.40 in moderately differentiated tumor, and 1.60 ± 0.24 in poorly differentiated tumor. Thus, the mean score of P-gp expression was small in the benign or low-grade malignant tumor, but large in the high-grade malignant tumors. Comparing of Na, K-ATPase expression (score 0, 1 and 2) to the histopathological type of tumor, the scores (mean) = 0.82 in well differentiated tumor, 1.44 in moderately differentiated tumor, and 1.50 in poorly differentiated tumors respectively.(Conclusion) 99m-Tc-MIBI and 201-TlCl scintigraphy showed different tendency of delayed uptake, and accurate diagnosis of tumor could be obtained by using both 99m-Tc-MIBI and 201-TlCl scintigraphy. P-gp and Na, K-ATPase expression were observed in accordance with the results of 99m-Tc-MIBI and 201-TlCl scintigraphy.
(临床评价)对于保留指数(延迟摄取/早期摄取),99m-Tc-MIBI在恶性肿瘤中显示保留指数低于1(平均值±SD=0.853±0.067),表明延迟摄取有降低的趋势。另一方面,201-TlCl闪烁显像的保留指数根据肿瘤的组织病理学类型分为三组。良性肿瘤中为0.81±0.06,高分化恶性肿瘤中为1.01±0.10,中分化肿瘤中为1.09±0.13,低分化肿瘤中为1.24±0.14。因此,平均保留指数在良性肿瘤中低于1,但在低分化肿瘤中高于1。恶性肿瘤组织病理学分级越高,保留指数越大。 (积累机制)至于P-gp表达(得分0、1和2)与肿瘤组织病理学类型之间的关系,良性肿瘤中得分(平均值±SD)=0.75±0.19,高分化肿瘤中0.71±0.36中分化肿瘤为 0.83 ± 0.40,低分化肿瘤为 1.60 ± 0.24。因此,与 Na、K-ATPase 表达(得分 0、1 和 2)相比,P-gp 表达的平均得分在良性或低度恶性肿瘤中较小,但在高度恶性肿瘤中较大。肿瘤的组织病理学类型,高分化肿瘤的得分(平均值)= 0.82,中分化肿瘤的得分(平均值)= 1.44,低分化肿瘤的得分(平均值)= 1.50 (结论) 99m-Tc-MIBI和201-TlCl闪烁显像显示不同的延迟摄取趋势,同时使用99m-Tc-MIBI和201-TlCl闪烁显像和P-gp可以得到准确的肿瘤诊断。根据 99m-Tc-MIBI 和 201-TlCl 闪烁扫描结果观察 ATPase 表达。
