[Trephine biopsy of the bone marrow in patients with hairy cell leukemia]

Insights

Bone marrow trephine biopsy is a superior diagnostic tool for hairy-cell leukemia (HCL). This method accurately identifies characteristic leukemia cell proliferation, aiding in HCL diagnosis and differentiation.

Area of Science:

  • Hematology
  • Oncology
  • Pathology

Context:

  • Study conducted on 13 patients with hairy-cell leukemia (HCL) at the Hematological Centre in Latvian SSR.
  • HCL diagnosis confirmed in all cases, with 9 patients diagnosed via bone marrow trephine biopsy.
  • Analysis of clinical and morphological features informed the classification of HCL variants.

Purpose:

  • To evaluate the diagnostic utility of bone marrow histological examination in hairy-cell leukemia.
  • To identify distinct clinical and histomorphological variants of HCL.
  • To recommend optimal diagnostic methods for HCL.

Summary:

  • Bone marrow trephine biopsy revealed characteristic leukemia cell proliferation in 9 out of 13 HCL patients.
  • Histomorphological analysis distinguished typical and atypical HCL variants, some resembling lymphoma or chronic lymphoid leukemia.
  • Clinical presentation allowed for identification of splenic and bone-marrow predominant HCL variants.

Impact:

  • Trephine biopsy is recommended as a more informative method than sternal puncture for HCL diagnosis and differential diagnosis.
  • Enhanced understanding of HCL heterogeneity through clinical and histomorphological classification.
  • Improved diagnostic accuracy for hairy-cell leukemia, potentially leading to earlier and more effective treatment strategies.
