Drug interaction analyses assessed the combined effect of Selinexor and Mitoxantrone. E2F7-mediated HR inhibition is a key mechanism underlying Selinexor activity in AML. The XPO1-E2F7-HR axis represents a potential therapeutic vulnerability, supporting the rational combination of Selinexor with DNA-damaging agents to improve AML treatment outcomes.

The patient underwent induction chemotherapy with cytarabine and mitoxantrone, followed by salvage therapy with venetoclax and azacitidine, resulting in morphologic remission. Subsequent haploidentical hematopoietic stem cell transplantation achieved remission, with ongoing hematologic recovery. This case underscores the limitations of conventional molecular assays in detecting cryptic fusions and highlights the critical role of comprehensive genomic profiling in refining subclassification and optimizing therapeutic strategies in pediatric AML.
Collectively, our findings establish TSPAN6 as a migrasome-related regulator driving adverse immunotherapy outcomes and responses. Targeting TSPAN6, potentially with mitoxantrone, presents a potential strategy to enhance immunotherapy efficacy.
