Summary

Achieving adequate surgical margins is crucial for local control in extremity soft tissue sarcomas (ESTS). A margin size less than 1 mm correlates with higher local recurrence, but neither margin status nor local recurrence impacts overall survival.

Area of Science:

  • Oncology
  • Surgical Oncology
  • Orthopedic Oncology

Background:

  • Extremity soft tissue sarcomas (ESTS) pose treatment challenges, necessitating evaluation of local control methods.
  • Understanding the relationship between surgical margins, local recurrence, and overall survival (OS) is vital for optimizing treatment strategies.

Purpose of the Study:

  • To determine the adequate surgical margin for local treatment of ESTS.
  • To investigate the correlation between local control and OS in ESTS patients.

Main Methods:

  • A retrospective review of 531 consecutive patients treated for primary ESTS between 1993 and 2012.
  • Analysis included tumor characteristics, margin status, adjuvant therapies (chemotherapy and radiotherapy), local recurrence (LR) rates, and OS.

Main Results:

  • A margin size less than 1 mm was significantly associated with increased LR in multivariate analysis.
  • Specific subtypes, such as epithelioid sarcoma and myxofibrosarcoma, also correlated with higher LR.
  • Tumor grade, size, margin status, and LR were not found to be predictors of OS.

Conclusions:

  • Surgical margin size less than 1 mm and specific tumor subtypes are linked to a higher risk of local recurrence in ESTS.
  • Neither margin status nor local recurrence rates appear to influence the overall survival of patients with ESTS.
