Sorafenib as maintenance therapy in FLT3+ acute myeloid leukemia post allogeneic transplantation: a case report

This case report highlights sorafenib as maintenance therapy postallogeneic hematopoietic stem cell transplantation (allo-HSCT) in a young patient with acute myeloid leukemia (AML) with FMS-like tirosine kinase-3 (FLT3)-internal tandem duplication (ITD) mutation. Given the high relapse risk in FLT3-ITD-positive AML, the tyrosine kinase inhibitor sorafenib was administered. Several studies have shown that sorafenib improves survival in younger AML patients when combined with chemotherapy, though side effects can limit use in older patients. Sorafenib is increasingly significant after allo-HSCT maintenance, offering a promising option for high-risk AML cases. In this case, the patient achieved long-term remission with minimal side effects.
