Introduction of tyrosine kinase inhibitors (TKIs) targeting BCR::ABL1 fusion protein has revolutionized frontline therapy, with successive generations of TKIs\u2014from imatinib to dasatinib and most recently ponatinib\u2014achieving progressively deeper and more durable molecular responses. Concurrently, the integration of immunotherapy, particularly blinatumomab, has enabled chemotherapy\u2010sparing approaches further improving tolerability and efficacy. These advances have fundamentally challenged the historical paradigm that allogeneic hematopoietic cell transplantation (HCT) is indispensable for all Ph+ ALL patients in first complete remission. The role of allogeneic HCT is often debated and increasingly individualized, guided by measurable residual disease (MRD) assessment, TKI generation, depth and duration of molecular response, and patient\u2010specific factors. Emerging data suggest that a subset of patients achieving early, deep MRD negativity with TKIs and immunotherapy may achieve durable remissions without transplant, though long\u2010term follow\u2010up remains limited. For patients proceeding to allogeneic HCT, optimization of transplant strategy\u2014including donor selection, conditioning intensity, graft\u2010versus\u2010host disease prophylaxis, and posttransplant TKI maintenance\u2014is critical to maximize graft\u2010versus\u2010leukemia effects while minimizing toxicity. Treatment\u2010free remission strategies following prolonged TKI maintenance in non\u2010transplant patients, and the integration of chimeric antigen receptor (CAR) T\u2010cell therapy as bridge, consolidation, or salvage, represent emerging frontiers. This review critically examines the contemporary role of allogeneic HCT in Ph+ ALL and provides a framework for transplant decision\u2010making in the contemporary era of targeted and cellular immunotherapy.<\/jats:p>","DOI":"10.1002\/ajh.70330","type":"journal-article","created":{"date-parts":[[2026,4,16]],"date-time":"2026-04-16T06:20:55Z","timestamp":1776320455000},"page":"1605-1617","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The
