Prognostic Factors and Outcomes for Post-Radiation Sarcoma—A Systematic Review and Meta-Analysis
Why the study?
Post-radiation sarcomas are secondary malignancies occurring years after radiotherapy, but due to low incidence, evidence on prognostic factors and management is limited.
What are the prognostic factors associated with overall survival in patients with post-radiation sarcoma?
Population
2438 patients with histologically confirmed post-radiation sarcomas across 28 studies
Comparison
Prognostic factors and management strategies
Design
Systematic review and meta-analysis
Key result
Complete (R0) surgical resection (pooled HR < 1.0) and management in specialized sarcoma centers were associated with improved overall survival in post-radiation sarcomas.

Meta-Analysis (n=2,438)
What are the prognostic factors associated with overall survival in patients with post-radiation sarcoma?
Complete surgical resection and management in specialized sarcoma centers are the most important factors associated with improved overall survival in patients with post-radiation sarcomas.
Effect estimate: pooled HR < 1.0
Harbrücker et al. (2026) conducted a meta-analysis in Post-radiation sarcomas (n=2,438). Prognostic factors (including complete surgical resection and specialized center management) was evaluated on Overall survival (pooled HR < 1.0). Complete (R0) surgical resection (pooled HR < 1.0) and management in specialized sarcoma centers were associated with improved overall survival in post-radiation sarcomas.
