    Skip metastasis (SM) in osteosarcoma is rare and indicates a poor prognosis. Modern chemotherapy and surgical interventions showed limited benefit in three treated cases, suggesting a need for new therapeutic strategies.

    Area of Science:

    • Oncology
    • Orthopedic Surgery
    • Medical Research

    Background:

    • Osteosarcoma is a primary bone malignancy.
    • Skip metastasis (SM) is an uncommon presentation of osteosarcoma.
    • The efficacy of current treatments for osteosarcoma with SM is not well-documented.

    Observation:

    • This study reports on three osteosarcoma patients with skip metastasis.
    • All patients underwent primary amputation followed by postoperative chemotherapy.
    • Pulmonary and subsequent bony metastases were observed in all patients.

    Findings:

    • The average disease-free interval was 6.7 months.
    • Patients did not show significant benefit from intensive chemotherapy or thoracotomy.
    • Extensive disease dissemination occurred without response to treatments.

    Implications:

    • Skip metastasis in osteosarcoma is a grave prognostic indicator.
    • Current adjuvant therapies may be insufficient for osteosarcoma with SM.
    • Alternative therapeutic strategies are necessary for improved patient outcomes.
