Myelodysplastic Syndrome (MDS)

Ninja Nerds,
Welcome to the Ninja Nerd Podcast with Zach and Rob! In this episode, we explore Myelodysplastic Syndrome (MDS), a group of hematologic disorders characterized by ineffective hematopoiesis and a risk of progression to acute myeloid leukemia (AML). We also discuss the pathophysiology of MDS, highlighting the clonal stem cell mutations that lead to dysplastic bone marrow changes and peripheral blood cytopenias.

Our discussion explores the clinical presentation of MDS, from common findings like fatigue, pallor, and bleeding tendencies to more concerning signs such as transfusion dependence and infection risk. We also cover the diagnostic approach, emphasizing the importance of bone marrow biopsy findings such as dysplastic cell morphology, ring sideroblasts, and blast percentages. Key scoring systems like the Revised International Prognostic Scoring System (IPSS-R) are discussed to guide risk stratification and treatment decisions.

In this episode, we break down treatment strategies for both low-risk and high-risk MDS, including supportive care with transfusions and growth factors, the role of hypomethylating agents like azacitidine and decitabine, and advanced interventions such as allogeneic stem cell transplantation.

Whether you’re preparing for exams, clinical rotations, or looking to expand your knowledge of hematology, this episode is packed with high-yield insights to help you understand this challenging topic.
