| Research Abstract |
The purpose of our study was to evaluate the degree of radiotoxicity to lymphocytes after strontium-89 therapy for bone metastases using γ-H2AX foci immunodetection. DNA damage to lymphocytes induced by Sr-89 in vivo should result in increased numbers of cells with nuclear foci stained by γ-H2AX. γ-H2AX foci immunodetection in lymphocytes may detect radiation-induced DNA damage associated with strontium-89 therapy for bone metastases, and may facilitate estimation of the radiation doses absorbed with thistherapy.
