Area of Science:

  • Hematology
  • Oncology
  • Clinical Pathology

Background:

  • Plasma cell dyscrasias (PCD) are a group of neoplastic disorders characterized by the proliferation of plasma cells.
  • Atypical plasmacytosis in bone marrow aspirates and osteolytic lesions are key indicators for PCD diagnosis.

Purpose of the Study:

  • To evaluate diagnostic methods for paraproteinemias, focusing on multiple myeloma and allied disorders.
  • To emphasize the utility of immunoelectrophoresis and disc electrophoresis in routine diagnostic workflows.

Main Methods:

  • Analysis of 72 patients with PCD diagnosed via bone marrow aspirate and radiological findings.
  • Serum protein electrophoresis and immunoelectrophoretic analysis for M band detection and myeloma typing.
  • Disc electrophoresis for urinary Bence Jones protein detection.

Main Results:

  • IgG myeloma was most prevalent (40 cases), followed by IgA myeloma (13 cases) and Light Chain Disease (12 cases).
  • Urinary Bence Jones proteins were detected in 34 cases, more frequently with IgA myeloma.
  • Kappa light chains were observed in 21 cases and lambda in nine, without significant clinical correlation.

Conclusions:

  • A triangular diagnostic approach, integrating serum and urine analysis, is recommended for paraproteinemias.
  • Immunoelectrophoresis is crucial for typing multiple myeloma, while disc electrophoresis aids in detecting urinary Bence Jones proteins.
