This study reviewed bone lymphoma cases, finding radiographic patterns alone cannot predict type or prognosis. Staging, particularly the Mayo Staging System, is crucial for assessing skeletal lymphoma outcomes.

Area of Science:

  • Oncology
  • Radiology
  • Pathology

Background:

  • Bone lymphoma, encompassing Hodgkin disease (HD) and non-Hodgkin lymphoma (NHL), presents diagnostic and prognostic challenges.
  • Understanding the correlation between histologic subtypes, osseous involvement patterns, and radiographic features is vital for patient management.

Purpose of the Study:

  • To retrospectively analyze skeletal lymphoma cases to correlate histologic type with sites of bone involvement, radiographic destruction patterns, and prognosis.
  • To evaluate the utility of radiographic findings in predicting lymphoma subtype and patient outcomes.
  • To compare the effectiveness of traditional staging systems with the Mayo Staging System for skeletal lymphoma.

Main Methods:

  • Retrospective review of medical records from forty-two patients diagnosed with bone lymphoma (11 HD, 31 NHL).

  • Analysis of radiographic patterns of bone destruction, including vertebral sclerosis, permeative destruction, and periosteal reactions.
  • Correlation of histologic findings with sites of osseous involvement and patient prognosis.
  • Main Results:

    • The vertebral column was the most frequent site for axial involvement, and the femur was the most common site overall.
    • In HD, vertebral sclerosis was the predominant radiographic pattern.
    • In NHL, permeative destruction was the most common pattern, with unusual periosteal reactions observed in some cases.

    Conclusions:

    • Radiographic patterns of bone involvement alone are insufficient to predict histologic type or prognosis in skeletal lymphoma.
    • Patient staging remains the most critical prognostic indicator.
    • The Mayo Staging System, which considers the temporal relationship of osseous disease to nodal or soft-tissue disease, is preferred over the Ann Arbor Staging System for skeletal lymphoma.
