Is myelodysplastic syndrome serious?

Myelodysplastic syndromes (MDS) are a group of serious malignant hematologic disorders primarily caused by abnormal proliferation and differentiation of hematopoietic stem cells. This condition leads to ineffective hematopoiesis, refractory blood cell deficiencies, and bone marrow failure, and carries a high risk of progression to acute myeloid leukemia (AML). MDS presents with various symptoms, including anemia, fever, and bleeding, which can significantly impair patients' quality of life. Prognosis varies considerably among MDS patients, and treatment must be individualized. Patients with low-risk MDS may achieve disease stabilization and long-term survival through treatment, whereas high-risk MDS generally carries a poor prognosis and is difficult to cure, with treatment focusing mainly on controlling disease progression and delaying deterioration using medications. For patients with severe disease, allogeneic hematopoietic stem cell transplantation may be an effective therapeutic option, although it is not suitable for all patients.
