Although they are not common, it is estimated that, worldwide, 3 to 4 new cases are detected each year per 100,000 inhabitants, being more frequent in people over 65 years of age.
Myeloid neoplasms are a group of diseases in which the cells of the bone marrow, responsible for producing blood cells, undergo genetic alterations. These alterations, which prevent the normal production of red blood cells, white blood cells, and platelets, cause myelodysplastic syndromes. Myelodysplastic syndromes (MDS) are a diverse group of disorders in which the bone marrow does not produce enough healthy blood cells. These diseases can range from mild forms that require little or no treatment to more aggressive forms that can evolve into acute myeloid leukemia (AML). The impact on health ranges from fatigue and anemia to severe infections and bleeding. Essentially, these conditions represent a failure in the blood cell production process, which affects the body’s ability to function properly.
Symptoms of myelodysplastic syndromes
The symptoms of myelodysplastic syndromes can be varied and, in many cases, subtle at first. The presentation of these symptoms depends on the type and severity of the disease, as well as the patient’s overall health. It is important to pay attention to the signals the body sends and seek medical attention if you experience persistent or worrying symptoms. Some of the most common symptoms include:
Fatigue and generalized weakness:
feeling of extreme tiredness or lack of energy, even after rest.
Shortness of breath:
feeling of shortness of breath or difficulty breathing, especially during physical activity.
Unusual paleness:
pale coloration of the skin, gums, and nail bed.
Easy bleeding or bruising:
tendency to bruise easily or bleed for a long time after minor cuts.
Frequent infections:
increased susceptibility to infections due to decreased production of white blood cells.
Unintentional weight loss:
unexplained decrease in body weight.
It is important to remember that these symptoms can be caused by other conditions, so it is essential to consult a doctor to obtain an accurate diagnosis. The medical evaluation will determine the underlying cause of the symptoms and rule out or confirm the presence of a myeloid neoplasm or a myelodysplastic syndrome.
Classification of myelodysplastic syndromes
The classification of myeloid neoplasms and myelodysplastic syndromes is a complex process that aims to group diseases according to their characteristics and prognosis. This classification is essential for guiding treatment decisions and predicting the progression of the disease. The classification criteria are based on several factors, such as the type of blood cells affected, the number of blasts (immature cells) in the bone marrow, and the presence of certain genetic alterations. Some common classifications include:
Refractory anemia: characterized by a deficiency of red blood cells.
Refractory cytopenia with multilineage dysplasia: deficiency of two or more types of blood cells with abnormalities in their development.
Refractory anemia with excess blasts: presence of a high number of immature cells in the bone marrow.
Chronic myelomonocytic leukemia: myeloproliferative disorder with features of both myelodysplastic syndromes and myeloid leukemias.
Causes of myeloid neoplasms and myelodysplastic syndromes
The exact causes of myelodysplastic syndromes are unknown in many cases. However, it is believed that a combination of genetic and environmental factors may play a role in the development of these diseases. Research continues to identify the precise mechanisms that lead to these alterations in the bone marrow.
Risk factors for myeloid neoplasms and myelodysplastic syndromes
While the exact causes of these diseases are often unknown, there are risk factors that can increase the likelihood of developing myeloid neoplasms and myelodysplastic syndromes. Identifying these risk factors can help people to take preventive measures and to be more alert to symptoms. Some of the risk factors associated with these diseases include:
Old age: the risk increases significantly with age, being more common in people over 60 years old.
Exposure to certain chemicals, such as benzene: prolonged exposure to certain industrial chemicals may increase the risk.
Prior treatment with chemotherapy or radiotherapy: having received these treatments for other diseases may increase the risk of developing myeloid neoplasms and myelodysplastic syndromes.
Smoking: smoking has been associated with an increased risk of developing these diseases.
Complications of myelodysplastic syndromes
Myelodysplastic syndromes can lead to various complications that affect the health and quality of life of patients. These complications can vary depending on the type and severity of the disease, as well as the response to treatment. It is essential to be aware of these potential complications and work closely with the medical team to manage them appropriately. Some of the most common complications include:
Severe anemia: a deficiency in red blood cells can cause extreme fatigue, weakness, and difficulty breathing.
Recurrent infections: a decrease in white blood cells increases susceptibility to infections.
Excessive bleeding: a lack of platelets can cause easy bleeding and bruising.
Progression to acute myeloid leukemia (AML): in some cases, myelodysplastic syndromes can transform into an aggressive form of blood cancer.
If you experience any of these symptoms, it is essential to consult a healthcare provider for an accurate diagnosis and appropriate treatment. as, es fundamental consultar a un médico para un diagnóstico y tratamiento adecuados.
Diagnosis of myelodysplastic syndromes
The diagnosis of myelodysplastic syndromes requires a thorough evaluation by a specialist physician. The diagnosis process generally involves a series of tests and procedures designed to identify abnormal cells in the bone marrow and assess the extent of the disease. It is essential to provide the doctor with a complete medical history and describe in detail the symptoms experienced. The diagnostic process generally includes:
Medical history and physical examination: the doctor will ask about symptoms, medical history and risk factors.
Blood tests: comprehensive blood tests will be performed to assess the levels of different types of blood cells, including red blood cells, white blood cells, and platelets. Tests can also be performed to assess kidney and liver function, as well as to detect infections or other conditions that may be contributing to the symptoms.
Bone marrow aspiration and biopsy: this procedure involves extracting a small sample of bone marrow, usually from the hip bone, for examination under a microscope. Bone marrow aspiration allows for the evaluation of cellularity, the presence of abnormal cells, and the proportion of blasts (immature cells). Bone marrow biopsy provides information about the structure of the bone marrow and the presence of fibrosis.
Cytogenetic and molecular studies: bone marrow cells are analyzed to detect chromosomal or genetic abnormalities. Cytogenetic tests look for changes in chromosomes, while molecular tests identify specific genetic mutations. These tests are crucial for classifying the disease and determining the prognosis.

Treatments for myelodysplastic syndromes
The treatment of myelodysplastic syndromes is based on a comprehensive evaluation of each patient, considering the type and severity of the disease, as well as the patient’s age, general health status, and preferences. The primary goal of treatment is to control the disease, relieve symptoms, and improve quality of life. Some of the common treatment options include:
Blood transfusions: red blood cell transfusions are used to relieve the symptoms of anemia and improve oxygen supply to tissues. Platelet transfusions may be necessary to prevent or control bleeding.
Growth factors: these medications, such as erythropoietin and filgrastim, a granulocyte colony-stimulating factor (G-CSF), can stimulate the production of blood cells and reduce the need for transfusions.
Chemotherapy: chemotherapeutic drugs are used to destroy abnormal cells in the bone marrow and prevent the progression of the disease. The choice of drugs and the duration of treatment depend on the type and severity of the disease.
Stem cell transplantation: in more severe cases, a stem cell transplant may be considered to replace the damaged bone marrow with healthy cells. This procedure involves the infusion of healthy stem cells, either from the patient themselves (autologous transplant) or from a compatible donor (allogeneic transplant).
Supportive therapy: it is essential for preventing and treating infections, controlling bleeding, and relieving other symptoms. This may include the use of antibiotics, antivirals, and antifungals, as well as medications to control nausea and pain.
The team of professionals at HM Hospitales works in a coordinated manner to provide comprehensive and personalized care to each patient. Hematologists, radiation oncologists, and other specialists may participate in the treatment of these diseases.
