After ruxolitinib therapy, he later developed leukocytosis and 2% circulating blasts. Repeat marrow demonstrated ≥ 15% ring sideroblasts. Retrospectively, the initial biopsy fulfills ICC 2022 criteria for MDS/MPN-SF3B1-T, highlighting the diagnostic value of genetics-integrated classification in fibrotic marrows.
Overall, our findings suggest that TMZ may induce oncogenic miRNA expression as part of an adaptive response, while ruxolitinib may counteract this effect. Targeting miRNA-mediated regulatory networks in combination with pathway inhibition may represent a promising strategy to overcome therapeutic resistance in glioblastoma.

Treatment strategies included supportive care, interferon, hydroxyurea, and ruxolitinib. PMF and SMF demonstrate distinct clinical phenotypes despite sharing bone marrow fibrosis as a common endpoint. The mutational landscape highlights the genetic heterogeneity of MF and underscores the importance of integrating clinical, pathological, and molecular information to improve disease characterization and guide individualized management.
