Tumor infiltration of the bone marrow: comparative study using computed tomography.

G Hermann, J S Rose, L Strauss

    Skeletal Radiology
    |January 1, 1984
    PubMed
    Summary

    Computed tomography (CT) accurately maps bone tumor extent in patients. This imaging technique precisely identifies malignant tissue infiltration, aiding surgical planning for bone tumor resection and amputation.

    Area of Science:

    • Oncology
    • Radiology
    • Orthopedic Surgery

    Background:

    • Malignant primary bone tumors require accurate assessment for surgical intervention.
    • Preoperative evaluation of tumor extent is crucial for limb-sparing surgery and amputation planning.

    Observation:

    • Five patients with malignant primary bone tumors underwent preoperative computed tomography (CT) of the medullary cavity.
    • The contralateral extremity served as a control for comparison.

    Findings:

    • Positive attenuation coefficient on CT scans indicated the extent of tumor infiltration in the medullary cavity.
    • The correlation between preoperative CT measurements and pathological findings ranged from 1-8 mm, achieving over 94% accuracy.

    Implications:

    • CT imaging offers a highly accurate, non-invasive method for preoperative staging of primary bone tumors.
    • Improved accuracy in defining tumor margins can optimize surgical strategies, potentially leading to better patient outcomes and reduced recurrence rates.
