PMID: 42086171.<\/p>\n<p>&nbsp;<\/p>\n<h2 class=\"title\">Abstract<\/h2>\n<p>Hematopoietic stem cell transplantation (HSCT) is essential for curing high-risk or relapsed acute leukemia but entails lifelong morbidities. Adolescents and young adults may be particularly vulnerable; however, data on the global risk of long-term complications in survivors who underwent HSCT during adolescence are lacking. Using the French Leuc\u00e9mie Enfant Adolescent cohort, we compared late complications and quality of life (QoL) in survivors transplanted at \u226515 versus &lt;15 yr. We included 168 adolescents (\u226515 yr of age at HSCT) and 446 children (&lt;15 yr of age at HSCT) matched at best 1:3 on sex, type of leukemia, total body irradiation use, history of relapse, and follow-up duration. Cumulative morbidity was modelled with a five-state multistate model (0 to \u22654 complications). After a mean follow-up of 8.8 yr for adolescents and 9.5 yr for children, adolescents had a mean of 2.1 \u00b1 0.1 complications compared with 1.6 \u00b1 0.1 in younger survivors (P &lt; .001). Higher incidences were noted for cardiomyopathy, chronic kidney disease, secondary neoplasms, iron overload, and osteonecrosis. The multi-state model revealed earlier onset and faster accumulation of complications in adolescents. QoL scores did not differ between groups. HSCT during adolescence is associated with earlier and heavier long-term morbidity, underscoring the need for age-tailored survivorship care and integration of adolescent and young adults-specific risks into follow-up guidelines.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Pessarossi L, Poir\u00e9e M, Dalle JH, Visentin S, Domenech C, Renard C, Pochon C, Baruchel A, Fahd M, Gandemer V, [&hellip;]<\/p>\n","protected":false},"template":"","keywords":[],"class_list":["post-6283","publications_science","type-publications_science","status-publish","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.9 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>49.
