Radiation Injury Treatment Network: Leveraging existing expertise to provide radiation casualty management David Weinstock, MD Dana-Farber/Harvard Cancer Center Radiation Injury Treatment Network dweinstock@partners.org
Radiation Injury Treatment Network (RITN): Definition • Voluntary network of 47 academic medical centers, 7 blood donor centers and 7 umbilical cord blood banks • Organized by National Marrow Donor Program and American Society of Blood and Marrow Transplantation • Supported by the US Navy • Coordinated with the Office of the ASPR, DHHS
Radiation Injury Treatment Network (RITN): Pre-event • Education and training: • REAC/TS mini-course • Grand rounds and online presentations (<2300 trained) • REMM (www.remm.nlm.gov) treatment algorithms • Annual tabletop exercises • International consensus guidelines • National planning • Scarce Resources project • National Planning Guidance • State and Local Planners Playbook for Medical Response to a Nuclear Detonation
State and Local Planners Playbook for Medical Response to a Nuclear Detonation • 0-76, Be aware of the Radiation Injury Treatment Network (RITN) • I-19, HHS activation of National Disaster Medical System (NDMS) and other HHS assets (DMATs and burn teams). HHS to activate AABB TF for blood supports through Assistant Secretary for Health (ASH) activate RITN • II-6, Prepare for air-based transfer of victims to other jurisdictions, NDMS hospitals, RITN and Veterans Administration hospitals. • II-36, Support transfer and tracking of victims and potential victims of acute radiation syndrome to regional, NDMS, and RITN centers • II-42, Work with hospitals to identify patients for transfer to regional facilities, NDMS, RITN centers or burn facilities. • III-6, Continue transfer of victims who may need delayed medical care to National Disaster Medical System (NDMS), RITN and other jurisdictions.
Radiation Injury Treatment Network (RITN):Response • Surge capacity • National guidance – online, teleconsult • Coordination of stem cell transplantation: • Donor searches (>10,000 per week) • Product harvesting and transport • Treatment guidelines

Alert and Notification Prepare to receive Patients Earliest patients arrive at distant RITN centers Preparation for HSCT Manifest illness Day: 0 3 10 21 35 60+ Initiate G-CSF Recovery Prodromal symptoms
~40 radiological accident victims have been reported More are known to have undergone HSCT after Chernobyl but details are limited Treated with a variety of approaches and HSC products Many had multiorgan dysfunction 4 survived more than one year All 4 reconstituted autologous hematopoiesis Unclear how many others would have Almost none received growth factors prior to HSCT 25% died of transplant-related mortality HSCT for radiological injury: the experience
Lessons learned from industrial accidents • Highly heterogeneous exposure • High dose rate - 22 second exposure at sterilization facility (15 Gy/min) • Responded to cytokines - Cytokine treatment only Gourmelon et al. Health Physics 2010
Ongoing Initiatives • Strengthen relationships with: • State/local/territorial public health • NDMS • Pediatric treatment guidelines • Support planning of outpatient and inpatient capabilities at non-RITN centers • Educate non-physician hospital staff 22
