Mantle cell lymphoma laboratory findings

Laboratory tests for mantle cell lymphoma include complete blood count (CBC), comprehensive metabolic panel, LDH levels, Hepatitis B testing if treatment with rituximab is planned, uric acid levels, beta-2-microglobulin, pregnancy testing in woman of child-bearing age, flow cytometry, immunohistochemistry, genetic testing and FISH.

Laboratory tests for mantle cell lymphoma include:^[1]

• Complete blood count (CBC) with differential count

• Pancytopenia or a leukemic presentation with extensive leukocytosis.^[2]

• Comprehensive metabolic panel^[3]
• LDH levels^[4]: Normal range is 100–190 U/L
• Hepatitis B testing if treatment with rituximab is planned^[5]
• Uric acid levels: Normal range is 2.4-6.0 mg/dL in females and 3.4-7.0 mg/dL in males.
• Beta-2-microglobulin^[6]: Normal range is 0-3 µg/mL.
• Pregnancy testing in woman of child-bearing age
• Flow cytometry
• Immunohistochemistry^[7][8]

• CD19, CD20, CD22, CD43, CD79a, CD5, and FMC7 typically are positive, whereas CD23, CD10, CD200, and BCL6 are usually negative
• Overexpression of Cyclin D1
• SOX11 expression

• Genetic testing^[9]

• Translocation t(11;14)(q13;q32) in virtually all cases
• Mutation or deletions of ATM gene

• FISH (fluorescence in situ hybridization):
  • FISH can be used to detect the translocation t(11;14), which is found in most of MCL patients.^[10]
