This systematic review evaluated the outcomes of stereotactic body radiotherapy (SBRT) for spinal metastases in prostate cancer, focusing on hormone-sensitive (HSPC) versus castration-resistant (CRPC) disease. The review included five studies with 322 patients, revealing that local control rates exceeded 90% at 1-2 years, with HSPC patients showing significantly better overall survival compared to CRPC.
Key findings
- Local control rates for spinal SBRT exceeded 90% at 1-2 years.
- Overall survival rates were markedly higher in HSPC patients compared to CRPC.
- Approximately half of symptomatic patients experienced complete or partial pain relief.
- Vertebral compression fracture rates ranged from 4-10%, with low treatment-related toxicity.
Why it matters
Understanding the differential outcomes of SBRT in hormone-sensitive versus castration-resistant prostate cancer can guide treatment decisions and improve patient management strategies for spinal metastases.
What to keep in mind
The findings are based on a limited number of studies, primarily non-randomised, and require further prospective validation.
