Abstract

BACKGROUND

Early detection of cellular events is important to predict the outcome of the patients. This study was aimed to use (99m)Tc EC-annexin V to image tumor cells undergoing apoptosis.

METHODS

In 10 patients with breast cancer, scintigraphic images and dosimetric estimates were obtained after administering (99m)Tc EC-annexin V.

RESULTS

Nine of the 10 cases showed detectable (99m)Tc EC-annexin V uptake in tumor. Higher values of T/N ratios are associated with patient after treatment.

CONCLUSIONS

Apoptosis can be quantified using (99m)Tc EC-annexin V.

摘要

背景

早期检测细胞事件对于预测患者的预后很重要。本研究旨在使用(99m)锝标记的依 Annexin V 来对发生凋亡的肿瘤细胞进行成像。

方法

对 10 例乳腺癌患者给予(99m)锝标记的依 Annexin V 后,获取闪烁扫描图像和剂量学估计值。

结果

10 例患者中有 9 例在肿瘤中显示出可检测到的(99m)锝标记的依 Annexin V 摄取。较高的 T/N 比值与治疗后的患者相关。

结论

可以使用(99m)锝标记的依 Annexin V 对凋亡进行定量。
