Tumor size significantly impacts survival in synovial sarcoma patients. Larger tumors (>10 cm) show poor outcomes, highlighting the need for neoadjuvant chemotherapy trials in these cases.

Area of Science:

  • Orthopedics
  • Surgical Oncology
  • Medical Oncology

Background:

  • Synovial sarcoma is a rare soft tissue sarcoma.
  • Prognostic factors for localized synovial sarcoma require further elucidation.

Purpose of the Study:

  • To identify prognostic variables in patients with synovial sarcoma.
  • To evaluate the impact of tumor size on survival outcomes.

Main Methods:

  • Retrospective review of 38 synovial sarcoma patients treated between 1976 and 1994.
  • Histologic confirmation and consistent treatment protocols including surgical excision and perioperative radiation therapy.
  • Analysis of prognostic variables: histologic grade, subtype, surgical margin, recurrence, age, and tumor size.

Main Results:

  • Tumor size demonstrated a strong statistical association with survival in localized disease.
  • Patients with tumors <5 cm had 100% survival; 5-10 cm tumors had 75% survival; >10 cm tumors had 20% survival.
  • Metastatic disease at presentation resulted in a poor prognosis.

Conclusions:

  • Tumor size is a critical prognostic factor in localized synovial sarcoma.
  • Neoadjuvant chemotherapy should be investigated for large synovial sarcomas (>10 cm).
