KARYOTYPING+FISH FOR MULTIPLE MYELOMA, BONE MARROW

What is Karyotyping with FISH for multiple myeloma on bone marrow test?

Karyotyping with FISH for multiple myeloma on bone marrow provides a comprehensive cytogenetic workup in multiple myeloma. Karyotyping (G‑banding) detects large-scale chromosomal changes and overall genomic complexity with prognostic impact. FISH on CD138+ plasma cells sensitively identifies key myeloma abnormalities such as IGH translocations, 1q gain, 1p/17p deletions, and hyperdiploidy. Together, these complementary methods enable accurate risk stratification and guide prognosis at diagnosis and relapse.

Why consider Karyotyping with FISH for multiple myeloma on bone marrow test?

Multiple myeloma (MM) is a genetically heterogeneous disease—meaning different patients’ myeloma cells can have various chromosomal abnormalities that affect prognosis and treatment response.

• Complementary Information: Karyotyping shows the overall structure and number of chromosomes, while FISH highlights specific genetic abnormalities, such as deletions, duplications, and translocations, that are linked to the disease. 
• Higher Detection Rate: Many Multiple Myeloma cells don't divide well in culture, making traditional karyotyping unreliable. FISH, however, can be performed on interphase (non-dividing) cells, detecting a higher number of abnormalities than karyotyping alone. 
• Prognostic Significance:Certain genetic abnormalities, are known to be associated with different outcomes and treatment responses in Multiple Myeloma patients. FISH helps identify these high-risk features. 
• Risk-Adapted Treatment: The genetic information gathered from these tests allows doctors to stratify patients by risk and tailor treatment strategies, ensuring patients receive the most effective care for their specific disease type. 
• Complete Evaluation:Performing both tests together provides more unique information than either test alone, offering a more thorough and complete cytogenetic workup for the patient. 

Who should get this Karyotyping with FISH for multiple myeloma on bone marrow test?

• All Patients with Confirmed or Suspected Multiple Myeloma
• Patients with Smoldering (Asymptomatic) Multiple Myeloma
• Patients Undergoing Treatment or Relapse
• Patients Considered for Stem Cell Transplant.

More Information about Karyotyping with FISH for multiple myeloma on bone marrow test

Multiple myeloma (MM) is a type of blood cancer that arises from plasma cells, a type of white blood cell found in the bone marrow. In multiple myeloma, these plasma cells become abnormal (malignant) and multiply uncontrollably, interfering with normal blood cell production and causing various complications.
