    Isotope scanning did not better define osteosarcoma bone marrow spread than X-rays. Despite imaging and histology showing clear surgical margins, three local osteosarcoma recurrences occurred.

    Area of Science:

    • Orthopedic Oncology
    • Diagnostic Imaging

    Background:

    • Osteosarcoma is a primary bone malignancy requiring accurate local staging.
    • Accurate assessment of tumor extension is crucial for surgical planning and prognosis.

    Purpose of the Study:

    • To evaluate the utility of isotopic scanning in determining the local extent of osteosarcoma.
    • To compare isotopic scanning with conventional roentgenography and histology for tumor staging.

    Main Methods:

    • Retrospective analysis of 13 patients with biopsy-proven osteosarcoma.
    • Evaluation of isotopic scans, roentgenograms, and histologic findings for tumor extent.

    Main Results:

    • Isotopic scanning did not reveal greater intramedullary tumor extension than roentgenography in any patient.

  • High correlation observed between roentgenogram, scan, and histologic evaluation of tumor extent.
  • No evidence of malignancy near surgical margins in imaging or histology.

    • Conclusions:

    • Isotopic scanning offers no additional benefit over routine roentgenography for assessing intramedullary osteosarcoma extension.
    • Despite negative margins on imaging and histology, local osteosarcoma recurrences remain a challenge.
