Imaging and dosimetry of 99mTc EC annexin V: preliminary clinical study targeting apoptosis in breast tumors.
Academic Article
Overview
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.
