Summary

Adjuvant radiotherapy and metastasis development significantly impact local recurrence in soft-tissue sarcoma patients. Metastasis and age are key factors for overall survival in operable cases.

Area of Science:

  • Oncology
  • Surgical Oncology
  • Radiation Oncology

Background:

  • Soft-tissue sarcomas are rare malignancies requiring precise prognostic factor identification.
  • Understanding factors influencing local recurrence and overall survival is crucial for treatment optimization.

Purpose of the Study:

  • To determine prognostic factors for local failure and overall survival in operable soft-tissue sarcoma.
  • To evaluate the impact of adjuvant radiotherapy on outcomes.

Main Methods:

  • Retrospective analysis of 77 patients with localized soft-tissue sarcoma.
  • Assessment of prognostic factors including tumor grade, resection margins, radiotherapy, and metastasis development.
  • Univariate and multivariate analyses to identify significant predictors of survival and recurrence.

Main Results:

  • The 5-year local recurrence-free survival rate was 70.6%.
  • Adjuvant radiotherapy and metastasis development were significant prognostic factors for local recurrence.
  • High-grade tumors, local recurrence, and metastasis were adverse prognostic factors in univariate analysis; metastasis and age in multivariate analysis.
  • Radiotherapy showed improved efficacy in larger tumors, marginal resections, extremity locations, and high-grade tumors.

Conclusions:

  • Adjuvant radiotherapy is important for local control in soft-tissue sarcoma.
  • Metastasis development and patient age are critical prognostic factors for overall survival.
  • Optimizing treatment strategies requires considering these prognostic indicators.
