Area of Science:

  • Oncology
  • Head and Neck Surgery
  • Skeletal Biology

Background:

  • Craniofacial osteosarcoma is a rare malignancy of the head and neck.
  • Limited data exists on its clinical presentation and optimal management.

Purpose of the Study:

  • To retrospectively analyze the clinical course of patients with craniofacial osteosarcoma.
  • To identify prognostic factors for recurrence and survival.

Main Methods:

  • Retrospective analysis of 15 patients with craniofacial osteosarcoma.
  • Evaluation of surgical margins, recurrence rates, and survival data.

Main Results:

  • Five out of 13 patients (36%) experienced recurrence after primary resection.
  • Positive surgical margins correlated with higher recurrence and reduced survival.

  • Salvage surgery and metastasectomy showed potential survival benefits.

    • Conclusions:

    • Positive surgical margins are significant predictors of recurrence and survival in craniofacial osteosarcoma.
    • Aggressive surgical management, including salvage and metastasectomy, may improve patient outcomes.
