Recent advancements enhance malignant lymphoma (ML) diagnosis and therapy through immunohistology and flow cytometry. New ML types are identified, with specific subtypes like MALT lymphomas showing distinct organ distributions and prognostic indicators.

Area of Science:

  • Hematology
  • Oncology
  • Pathology

Context:

  • Significant advancements in malignant lymphoma (ML) diagnosis, patient follow-up, and therapy over the last 15 years.
  • Diagnosis relies on functional morphology, primarily immunohistology.
  • New methods have led to the identification of novel ML subtypes.

Purpose:

  • To detail recent developments in the pathomorphological diagnosis, clinical follow-up, and therapy of malignant lymphomas.
  • To highlight the diagnostic utility of flow cytometry in assessing DNA content, aneuploidy, and proliferative activity for prognostic significance.
  • To investigate lymphocyte recirculation in ML dissemination using in vitro immunomorphological tests.

Summary:

  • New malignant lymphoma (ML) entities have been identified, with specific organ distributions noted, such as MALT-type B-cellular MLs in the gastrointestinal tract.

Related Experiment Videos

  • Flow cytometry is crucial for diagnosing MLs, determining aneuploidy, and assessing proliferative activity, which are significant prognostic factors.
  • In vitro studies show that B-cellular chronic lymphocytic leukemia (CLL) and plasma cell leukemia cells exhibit endothelial adherence, unlike multiple myeloma cells, suggesting a role in dissemination.

    • Impact:

    • Improved diagnostic accuracy and classification of malignant lymphomas.
    • Enhanced understanding of prognostic indicators for better patient management.
    • Insights into the mechanisms of ML dissemination, potentially leading to novel therapeutic strategies.
