Unique Challenges of Hematopoietic Cell Transplantation in Adolescent and Young Adults with Hematologic Malignancies.

Slow but definite progress has been made in recognizing the differences in disease biology, host factors, and psychosocial issues related to management of hematologic malignancies, including hematopoietic cell transplantation (HCT), in the adolescent and young adult (AYA) population. Improvement in survival rates among AYAs undergoing HCT for hematologic malignancies have paralleled those seen among children and older adults in the contemporary era. However, overall outcomes remain inferior compared with those in children owing largely to higher rates of treatment related mortality and late relapses in AYA HCT recipients. We review the unique issues and challenges facing AYAs with hematologic malignancies undergoing HCT, identify unmet needs and gaps in care, and describe potential strategies to address them. A patient-centric and multidisciplinary approach to AYA HCT care with lifelong follow-up is necessary to ensure long-term health.
