    Parosteal osteosarcoma, a bone cancer, has an excellent prognosis with surgical resection. Early-stage, low-grade tumors can be cured with adequate margins, while larger or recurrent tumors may require staged surgery.

    Area of Science:

    • Orthopedic Oncology
    • Surgical Pathology

    Background:

    • Parosteal osteosarcoma is a subtype of osteogenic sarcoma.
    • It generally presents with a favorable prognosis compared to other osteosarcomas.

    Purpose of the Study:

    • To evaluate the surgical management and outcomes for parosteal osteosarcoma.
    • To define treatment strategies based on tumor grade and size.

    Main Methods:

    • Review of case series focusing on surgical resection techniques.
    • Classification of tumors by grade (I-III) and size (<5 cm vs. larger).
    • Analysis of treatment outcomes including survival and recurrence rates.

    Main Results:

    • Adequate resection of low- and moderate-grade parosteal osteosarcoma leads to long-term survival.

  • Small, low-grade lesions (<5 cm) are effectively treated with en bloc resection and 2.5 cm margins.
  • Larger Grade I-II lesions and recurrences benefit from a two-stage resection six months apart.
  • Grade III or intramedullary-involved lesions require high-grade osteosarcoma treatment protocols.
  • Surgical challenges like pathologic fracture, neurovascular compromise, and joint function preservation were managed.

    • Conclusions:

    • Parosteal osteosarcoma management is tailored to tumor characteristics.
    • Surgical resection with appropriate margins and techniques offers excellent outcomes.
    • Staged resection is effective for larger or recurrent low-grade parosteal osteosarcoma.
