Area of Science:

  • Orthopedic Oncology
  • Surgical Oncology
  • Cancer Research

Background:

  • Osteosarcoma is an aggressive bone cancer with debated treatment outcomes.
  • Conflicting data exists regarding limb salvage surgery versus amputation for osteosarcoma patients.
  • Assessing survival and functional recovery is crucial for treatment decisions.

Purpose of the Study:

  • To compare clinical outcomes of limb salvage surgery versus amputation in osteosarcoma patients.
  • To provide evidence-based insights into optimal surgical management for osteosarcoma.
  • To analyze local recurrence, overall survival, and metastasis rates.

Main Methods:

  • A comprehensive meta-analysis of published literature was performed.
  • Searches included major databases: CNKI, Medline, Embase, Cochrane, Web of Science.
  • Study quality was assessed using the Newcastle-Ottawa scale; odds ratios were calculated.

Main Results:

  • 17 articles comprising 1343 osteosarcoma patients were analyzed.
  • No significant difference in local recurrence rates between limb salvage and amputation.
  • Limb salvage surgery demonstrated higher 5-year overall survival and lower metastasis occurrence.

Conclusions:

  • Limb salvage surgery is supported as an optimal treatment for osteosarcoma.
  • Evidence suggests improved survival and reduced metastasis with limb salvage.
  • This meta-analysis offers comprehensive data for surgical treatment choices.
