The Second Pediatric Blood and Marrow Transplant Consortium International Consensus Conference on Late Effects after Pediatric Hematopoietic Cell Transplantation: Defining the Unique Late Effects of Children Undergoing Hematopoietic Cell Transplantation for Immune Deficiencies, Inherited Marrow Failure Disorders, and Hemoglobinopathies

An international consensus conference sponsored by the Pediatric Blood and Marrow Transplant consortium entitled “Late Effects Screening and Recommendations Following Allogeneic Hematopoietic Cell Transplant for Immune Deficiency and Nonmalignant Hematologic Disease” was held in Minneapolis, Minnesota on May 10, 2016 and May 11, 2016. The purpose of the conference was to address the unmet need for greater understanding of and the screening for long-term complications in the growing population of survivors of transplantation for nonmalignant disorders. The conference focused on transplantation for hemoglobinopathy, immune deficiency, and inherited bone marrow syndromes. A multidisciplinary group of experts in the disease areas and transplantation late effects presented the current state of understanding of how the underlying disease, pretransplantation therapies, and transplantation-related factors uniquely interact to influence the development of late toxicities. Recommendations were put forth by the group for the late effects screening of survivors of transplantation for these nonmalignant disorders. The findings and recommendations that came from this conference will be presented in a series of 6 additional manuscripts in the upcoming months. In this manuscript, we explore the need for screening practices specific to the survivors of transplantation for nonmalignant diseases and the methodologic challenges associated with the study of these patients.
