Summary

Marginal excision, tumor necrosis, and extracompartmental location predict local recurrence in high-grade soft tissue sarcoma. These factors, along with Grade IV, male sex, and larger tumors, worsen patient survival.

Area of Science:

  • Orthopedics
  • Oncology
  • Surgical Pathology

Background:

  • Soft tissue sarcomas are malignant tumors with variable prognoses.
  • High-grade sarcomas (Grades III and IV) exhibit aggressive behavior and pose significant treatment challenges.
  • Understanding prognostic factors is crucial for optimizing patient management and outcomes.

Purpose of the Study:

  • To identify prognostic factors influencing local recurrence and survival in patients with high-grade soft tissue sarcoma of the locomotor system.
  • To analyze the impact of 15 distinct clinical and pathological variables on patient outcomes.

Main Methods:

  • Retrospective analysis of 144 patients diagnosed with high-grade (Grades III-IV) soft tissue sarcoma.
  • Minimum follow-up of 6 years or until death.

  • Statistical evaluation of 15 pre-defined prognostic factors.

    • Main Results:

    • Three factors were identified as significant risk factors for local recurrence: marginal excision, tumor necrosis, and extracompartmental tumor location.
    • Five factors were associated with decreased life expectancy: local recurrence, Grade IV histology, male sex, tumor necrosis, and increasing tumor size.

    Conclusions:

    • Surgical margins, tumor characteristics (necrosis), and tumor location are critical determinants of local recurrence in high-grade soft tissue sarcomas.
    • Prognosis is significantly poorer in patients with Grade IV tumors, male patients, those experiencing local recurrence, tumor necrosis, and larger tumor dimensions.
