Summary
Post-radiation sarcomas (PRS) are rare secondary cancers. Complete surgical resection and care at specialized sarcoma centers significantly improve survival, while chemotherapy and additional radiotherapy do not. Further research is needed for better risk stratification.
Area of Science:
- Oncology
- Radiation Oncology
- Surgical Oncology
Background:
- Post-radiation sarcomas (PRS) are rare secondary malignancies developing years after radiotherapy.
- Limited evidence exists on prognostic factors and optimal management due to low incidence.
Purpose of the Study:
- To systematically review prognostic factors and management outcomes for patients with post-radiation sarcomas (PRS).
- To identify key determinants of overall survival and recurrence in PRS patients.
Main Methods:
- A comprehensive literature search of MEDLINE, Embase, and Cochrane Library (1960-2026).
- Inclusion of observational cohort studies with histologically confirmed PRS and survival outcomes.
- Extraction of hazard ratios and assessment of risk of bias; primary outcome was overall survival.
Main Results:
- 28 studies with 2438 patients were analyzed; most were female, linked to breast radiation-associated angiosarcoma.
- Older age, larger tumor size, higher grade, and positive margins correlated with worse survival.
- Complete (R0) resection and treatment at specialized centers improved survival; chemotherapy/additional radiotherapy showed no benefit.
Conclusions:
- Post-radiation sarcomas (PRS) share prognostic factors with sporadic sarcomas.
- Complete surgical resection and specialized center management are crucial for improved PRS outcomes.
- Findings support centralized care and emphasize the need for prospective research in PRS.
