Overall survival of patients with adrenal metastases treated with SBRT based on one-year estimates; α/β=10 Gy in this model. The figure shows OS estimates at 50%, 80%, 90%, and 95% (blue dotted horizontal lines). The black dashed curves show the 95% confidence band and the GTV coverage dose scales are for EQD210, BED10, and equivalent doses in 3 and 5 fractions.
