  Aims: High dose 131I-meta iodobenzylguanidine (131I-mIBG) combined with radiosensitizing topotecan and peripheral blood stem cell support is a promising treatment regimen for children with neuroblastoma (NB). Here we present our first experiences, with particular focus on in vivo whole-body dosimetry and radiation exposure to family caregivers and hospital staff. Methods: Five children with relapsed or refractory NB were treated during 2012-2014. 131I-mIBG was administered in two fractions at two weeks apart, aiming for a total whole-body radiation-absorbed dose of 4 Gy. The 131I-mIBG activity for the 2nd administration was calculated on the basis of the measured whole-body dose following the 1st administration. Patients were isolated in a lead-shielded room, and all caregivers and staff received radiation safety training, and carried an electronic personal dosimeter. .. Read More»
