Overview of Myelodysplastic Syndromes

Myelodysplastic syndromes encompass a range of hematological conditions primarily seen in older adults. The term "myelodysplastic" itself reflects the dysregulated production of blood cells, resulting in ineffective hematopoiesis. Patients with MDS can experience a myriad of symptoms due to a shortage of red blood cells, white blood cells, or platelets, which leads to anemia, increased infection risk, and bleeding issues, respectively.

The progression of MDS can vary significantly. Some individuals may live many years with mild symptoms, while others may experience rapid disease progression, emphasizing the unpredictability of this group of disorders. Regular monitoring and a tailored approach to therapy are paramount.

Historical diagnostic methods categorically placed MDS in a gray area between benign and malignant hematological disorders. Recently, accumulating research has refined this classification, propelling MDS into a more distinct diagnostic arena. Identifying specific subtypes, such as RAEB-2, allows for prognosis prediction and treatment optimization.

Classification of MDS Subtypes

MDS are classified based on several factors, including the patient’s blood cell morphology and cytogenetic abnormalities. This classification is pivotal, as it shapes the clinical approach to treatment and monitoring. The three primary classifications of MDS consist of the following:

Refractory Anemia (RA): Characterized by a low red blood cell count that does not respond to standard treatments, often seen in patients with mild dysplasia.
Refractory Cytopenia with Excess Blasts (RAEB): This is where RAEB-1 and RAEB-2 come into play. RAEB-2 is the more severe form, indicating a higher percentage of blasts in the bone marrow, marking a critical juncture that can lead to transformation into AML.
