[Research Progress on Multiple Myeloma with Extramedullary Disease].

Area of Science:

• Hematology
• Oncology

Background:

• Multiple myeloma (MM) is a cancer of plasma cells.
• Extramedullary disease (EMD) occurs when MM spreads outside the bone marrow.
• EMD in MM patients is associated with poor treatment outcomes.

Purpose of the Study:

• To review current research on the pathogenesis of MM with EMD.
• To summarize the clinical features and diagnostic challenges of MM-EMD.
• To discuss therapeutic strategies and prognostic factors for MM patients with EMD.

Main Methods:

• Literature review of studies on multiple myeloma and extramedullary disease.
• Analysis of research progress in MM-EMD pathogenesis.
• Synthesis of clinical data on MM-EMD features, treatment, and prognosis.

Main Results:

• Extramedullary disease can manifest at diagnosis or during MM treatment.
• Patients with EMD often show a limited response to standard chemotherapy.
• Prognosis for MM patients with EMD is generally unfavorable.

Conclusions:

• Understanding MM-EMD pathogenesis is crucial for developing targeted therapies.
• Early detection and tailored treatment approaches are needed for MM-EMD.
• Further research is required to improve the survival and quality of life for MM patients with EMD.
