Summary
Reporting surgical margins in sarcoma limb salvage surgery lacks standardization. Over a third of studies omit margin status, hindering accurate assessment of treatment outcomes and survival.
Area of Science:
- Oncology
- Surgical Pathology
- Orthopedic Surgery
Background:
- Surgical margins are critical for tumor surgery outcomes.
- No universal classification system for surgical margins exists.
- Prevalence of margin reporting methods in sarcoma literature is unclear.
Purpose of the Study:
- To analyze the reporting of surgical margins in limb salvage surgery for sarcoma.
- To identify trends in margin classification and reporting over time.
Main Methods:
- PubMed literature search (1980-2013) for sarcoma limb salvage surgery articles.
- Data extraction on margin classification, journal/author specialty, and institution location.
- Analysis of reporting methods, including Enneking's classification and dichotomous (positive/negative) reporting.
Main Results:
- 35% of articles did not report surgical margins.
- Enneking's classification was used in 55% of papers that reported margins.
- Increasing trends observed in reporting margins by residual tumor (R) classification and dichotomously.
Conclusions:
- A standardized method for reporting surgical margins in sarcoma limb salvage is absent.
- Incomplete margin reporting (over 1/3 of studies) compromises interpretation of oncologic outcomes.
- Advocacy for a simple, reproducible, and prognostic surgical margin reporting system is needed.
