Patients with metastatic disease treated with SBRT have worse survival outcomes. Kaplan-Meier curves of PFS and OST by metastasis at presentation. Panel A: Median PFST of 90 (95% CI = 24–139) vs. 241 days (95% CI = 134–475 days) for those with metastatic disease (P = 0.009). Panel B: Median OST of 153 days (95% CI = 67–220) vs. 244 days (95% CI = 203–338) (P = 0.003). Tick marks indicate time of censoring, faded regions indicate 95% confidence intervals.
