Accurate subtyping of non-Hodgkin's lymphoma is crucial for patient prognosis. Advanced immunophenotyping and cytogenetic analysis are now essential for precise diagnosis, moving beyond traditional morphology alone.

Area of Science:

  • Hematology
  • Oncology
  • Immunology

Background:

  • Histological subtyping of non-Hodgkin's lymphomas (NHL) is critical for prognosis.
  • Current classifications into low, intermediate, and high grades are challenged by immunophenotypic and genotypic heterogeneity.
  • Specific NHL entities, like diffuse small cleaved-cell lymphoma, encompass diverse cell types (B-cell and T-cell).

Purpose of the Study:

  • To highlight the heterogeneity within histological NHL subtypes.
  • To emphasize the need for integrated diagnostic approaches combining morphology, immunophenotyping, and cytogenetics.
  • To underscore the importance of precise subtyping for understanding mantle-cell lymphoma behavior and treatment response.

Main Methods:

  • Review of histological, immunophenotypic, and cytogenetic data for NHL classification.

  • Analysis of cell morphology, B-cell markers, surface immunoglobulins, CD5, CD10 expression, and chromosomal translocations (t(11;14)).
  • Comparison of mantle-cell lymphomas (United States: mantle-zone lymphoma; Europe: centrocytic lymphoma) with other NHL subtypes.

    • Main Results:

    • Histological subtypes of NHL are heterogeneous, requiring advanced diagnostic methods.
    • Mantle-cell lymphomas, mantle-zone lymphomas, and centrocytic lymphomas share similar characteristics (small round/cleaved cells, B-cell markers, CD5+, CD10-, t(11;14)).
    • These entities are distinct from follicle centre-cell lymphomas and small lymphocytic lymphomas.

    Conclusions:

    • Precise subtyping of NHL is mandatory for accurate prognostication and treatment planning.
    • Immunophenotyping and cytogenetic analysis are indispensable tools for refining NHL diagnosis.
    • Further research is needed to fully document the behavior and therapeutic responsiveness of mantle-cell lymphomas.
