Long-term Effects of Myeloablative Allogeneic Hematopoietic Stem Cell Transplantation in Pediatric Patients with Acute Lymphoblastic Leukemia

Abstract

Purpose of Review

Allogeneic hematopoetic stem cell transplantation (HSCT) is a curative option for children and adolescents with high-risk leukemia. Although acute complications were reduced during the last decade, considerable late effects are still limiting the overall success rate. This article emphasizes the specific pediatric aspects of long-term aftercare following myeloablative HSCT and provides an organ-based overview that covers main clinical patterns, incidence, and risk factors enhanced by current references and screening guidelines.

Recent Findings

In the last years, several attempts were made to separate pediatric outcome data from findings in adults. It turned out that not only the indication for but also the time and the procedures of HSCT substantially differ. Nearly any organ might be affected after the complex transplantation process and includes endocrinopathies, musculoskeletal disorders, cardiopulmonary complications, and secondary malignancies.

Summary

Patients after HSCT in childhood have a high risk for developing a wide range of late sequelae and may benefit from regular screening and early intervention. The occurrence and patterns of late effects depend on the intensity and severity of conditioning and are strongly associated with patient's age at transplant and beginning of complications.
