Multiple myeloma: symptoms, diagnosis, and treatment

Definition of multiple myeloma

Multiple myeloma is a cancer that develops from plasma cells in the bone marrow and belongs to the group of hemoblastoses. The main signs of multiple myeloma are the excessive formation of monoclonal plasma cells that fill the bone marrow and destroy bones, as well as the production of monoclonal protein (M-protein), which can lead to organ dysfunctions. Diagnosis includes laboratory blood tests, bone marrow biopsy, as well as imaging methods such as X-ray and MRI for a more accurate assessment of the disease’s condition.

Etiology of multiple myeloma

Multiple myeloma is a malignant tumor disease characterized by an unjustified clonal proliferation of plasma cells in the bone marrow. The causes of multiple myeloma are not yet fully understood; however, various factors that may play a role in its onset have been identified. These include genetic predispositions, environmental influences, viral infections, as well as abnormalities in the immune system. More detailed studies and clinical data are needed for a complete understanding of the mechanisms and factors contributing to the development of this pathological process.

  • Genetic predispositions: Some genes may increase the risk of developing multiple myeloma.
  • Environmental exposure: Contact with certain harmful substances may contribute to the development of the disease.
  • Viral infections: Some viruses may play a role in initiating the process of developing multiple myeloma.
  • Immunological abnormalities: Disorders in the immune system may facilitate the formation of plasma cell tumors.
  • Bone marrow microenvironment: Characteristics of the bone marrow microenvironment may create conditions for the development of the pathological process, contributing to multiple myeloma.

The clinical picture of multiple myeloma

The clinical picture of multiple myeloma typically includes a variety of symptoms, such as weakness, weight loss, increased bone fractures, anemia, a higher tendency to infections, and elevated protein levels in the blood and urine. The disease may also present as bone pain, especially in the back or chest, as well as swelling, particularly in the face or legs. Patients with multiple myeloma often experience increased fatigue and kidney function disorders. These symptoms may vary depending on the stage of the disease and the overall condition of the patient.

  • Weakness and fatigue: is characterized by a constant feeling of tiredness and weakness, often leading to a disruption of usual daily activities.
  • Weight loss: patients often experience unexplained weight loss, which can be one of the first signs of the disease.
  • Increased bone fractures: the higher risk of bone fractures is caused by osteoporosis, which may be associated with multiple myeloma.
  • Anemia: a decrease in red blood cell levels can lead to reduced oxygen in the body and increased fatigue and weakness.
  • Bone pain: pain in the bones, especially in the back or chest, can be one of the characteristic manifestations of multiple myeloma.

Prospects for the treatment of multiple myeloma

Multiple myeloma is a complex disease, and medical experts continue to explore new treatment possibilities. Modern treatment methods include chemotherapy, proton therapy, anticonvulsants, immunotherapy, and bone marrow transplantation. Experts have noted the prospects of using new drugs such as proteasomes, immunoproteasome inhibitors, monoclonal antibodies, and other innovative therapies that could improve treatment outcomes for patients with multiple myeloma. An important aspect of the future development of treatment for this disease is a personalized approach that takes into account the genetic and molecular profiling of tumors, allowing for the creation of more effective and personalized therapeutic strategies.

Methods for diagnosing multiple myeloma

Diagnosis of multiple myeloma involves a variety of methods, such as a complete blood and urine test, measurement of blood monomeric protein B levels, protein electrophoresis in blood serum and urine, bone marrow biopsy with subsequent cytogenetic analysis, computed tomography of the skeleton, and other instrumental research methods. Methods of educational diagnosis, such as positron emission tomography (PET-CT) and magnetic resonance imaging (MRI), may be used to determine the stage and spread of the disease.

It is important to note that accurate and timely diagnosis of multiple myeloma plays a crucial role in choosing the optimal treatment strategy and prognosis for the patient. Comprehensive use of various diagnostic methods allows for a more precise assessment of the disease severity, identification of possible complications, and provides grounds for the appointment of effective therapy.

  • Complete blood and urine analysis: blood and urine indicators may indicate changes characteristic of multiple myeloma.
  • Measurement of serum monoclonal protein B levels: an elevated level of this protein may indicate the presence of multiple myeloma or its recurrence.
  • Protein electrophoresis: this method allows for the detection of changes in the types of proteins secreted by the tumor or destroyed by bone tissue.
  • Bone marrow biopsy with cytogenetic analysis: performing this procedure allows for the confirmation of the diagnosis and the determination of the genetic characteristics of tumor cells.
  • Computed tomography of the skeleton: this examination helps identify bone damage characteristic of multiple myeloma.

Methods of treating multiple myeloma

Treatment of multiple myeloma depends on the stage of the disease, the overall condition of the patient, and the presence of comorbidities. The main treatment methods include chemotherapy, bone marrow transplantation, targeted therapy, radiation therapy, and immunomodulatory agents. In recent years, innovative treatment methods have been developed, such as immunotherapy and CAR-T cells, which may represent promising approaches in the fight against this disease. However, the efficacy and safety of each method should be assessed individually in the context of the specific case and under the supervision of oncologists.

  • Chemotherapy: Chemotherapy is used to destroy malignant cells of multiple myeloma through the use of various drugs such as bortezomib, lenalidomide, and dexamethasone.
  • Bone Marrow Transplantation: Autologous stem cell transplantation may be recommended for some patients with multiple myeloma to replace damaged bone marrow cells with new healthy cells.
  • Targeted Therapy: This therapy targets specific molecular targets present on the surface of tumor cells, such as proteasome, angiogenesis, and others.
  • Radiation Therapy: Radiation therapy may be used to localize and destroy malignant cells of multiple myeloma by exposing them to ionizing radiation.
  • Immunomodulatory Drugs: Drugs such as thalidomide and lenalidomide can enhance the immune response and slow the progression of the disease.

Measures to prevent multiple myeloma

As of today, precise methods for preventing multiple myeloma have not been established, as the exact causes of its occurrence are not completely understood. However, several studies associate the risk of developing the disease with factors such as genetic predispositions and the environment. An important aspect of prevention may be a healthy lifestyle, which includes a balanced diet, regular physical activity, abstaining from harmful habits, and reducing exposure to possible carcinogens. Regular medical check-ups and consultations with specialists can also help identify pathology in the early stages and take necessary measures for its control and treatment.

  • Healthy lifestyle: Maintaining an active lifestyle, moderate physical exercise, and a balanced diet can promote overall well-being and reduce the risk of developing diseases, including multiple myeloma.
  • Avoiding carcinogens: Avoiding prolonged exposure to certain chemicals or radiation, carcinogens, as well as adhering to safety measures at work and home, is important for reducing risk factors for developing cancer.
  • Regular medical check-ups: Conducting regular medical examinations and screening tests allows for early detection of pathologies, including the initial manifestations of multiple myeloma.
  • Other preventive measures: Controlling diabetes and hyperproteinemia, careful handling of potentially hazardous substances, as well as vaccination against viral infections can also help reduce the risk of developing multiple myeloma.
  • Genetic counseling: Individuals with a family history of multiple myeloma or identified genetic predispositions are advised to consult with a geneticist to assess individual risk and develop appropriate preventive measures.
