Treatment Options for Myelodysplastic Syndromes in Older Adults

Understanding Myelodysplastic Syndromes in the Elderly

Myelodysplastic syndromes (MDS) are a group of disorders characterized by ineffective blood cell production in the bone marrow, commonly affecting older adults. One of the major concerns with MDS is its potential to progress into acute myeloid leukemia (AML), making early and proactive management essential. Given the age-related challenges faced by elderly patients—such as reduced physiological reserve and increased susceptibility to treatment complications—the primary goals of therapy shift toward improving quality of life and prolonging survival rather than pursuing aggressive cures.

Core Treatment Strategies for Senior Patients

Management of MDS in older individuals typically revolves around two main approaches: supportive care and disease-modifying therapies. Since many elderly patients cannot tolerate intensive treatments, the focus remains on symptom control, minimizing complications, and maintaining functional independence.

Supportive Care: Maintaining Stability and Preventing Complications

Supportive care forms the foundation of MDS treatment in aging populations. This includes regular red blood cell and platelet transfusions to manage anemia and prevent bleeding episodes. However, chronic transfusion dependence can lead to iron overload, which may damage vital organs such as the heart and liver. Therefore, iron chelation therapy is strongly recommended for patients receiving frequent red cell transfusions to reduce iron accumulation and mitigate long-term risks.

In addition, infection prevention plays a critical role. Neutropenia—low levels of white blood cells—increases vulnerability to infections. Prophylactic antibiotics, vaccinations, and strict hygiene practices are often advised. In some cases, growth factors like granulocyte colony-stimulating factor (G-CSF) may be used to boost white blood cell counts and lower infection rates.

Stimulating Blood Cell Production

Certain medications can help stimulate the bone marrow to produce more healthy blood cells. For instance, danazol, a synthetic androgen, has shown promise in reducing transfusion needs in selected MDS patients, particularly those with specific genetic markers. When combined with G-CSF, it may enhance hematopoietic response and improve blood counts over time.

Disease-Modifying Therapies: Targeting the Underlying Condition

For patients who are fit enough, hypomethylating agents such as azacitidine and decitabine are considered standard-of-care options. These drugs work by modifying gene expression in abnormal bone marrow cells, potentially delaying progression to leukemia and extending survival. Clinical studies have demonstrated that these agents can improve overall outcomes, even in elderly populations, although responses vary significantly between individuals.

Hematopoietic Stem Cell Transplantation: A Limited Option

While allogeneic stem cell transplantation remains the only curative approach for MDS, it carries substantial risks—especially for older adults. The procedure involves intense chemotherapy and immune suppression, followed by donor cell infusion, which can lead to severe complications including graft-versus-host disease (GVHD) and organ toxicity. Due to high treatment-related mortality and limited eligibility among seniors, transplant is generally not recommended for most elderly patients unless they are exceptionally healthy and have a suitable donor match.

A Personalized Approach to Long-Term Management

Treating MDS in older adults requires a highly individualized strategy that balances efficacy with safety. Factors such as performance status, comorbidities, cytogenetic profile, and patient preferences must all be taken into account when designing a treatment plan. Ongoing monitoring, regular lab assessments, and timely intervention adjustments are crucial for optimizing outcomes.

With advances in targeted therapies and better supportive care, many elderly patients with MDS can now experience improved energy levels, fewer symptoms, and longer survival. Multidisciplinary care involving hematologists, geriatricians, and supportive services ensures comprehensive management tailored to the unique needs of aging individuals.
