What was measured

Kaplan-Meier estimates will be used to plot local progression free survival.

Analysis population: No patients were alive at 12 months, so no analysis was done.

Groups in this outcome

Treatment (SBRT)

Participants undergo Stereotactic Body Radiation Therapy in 5 fractions at least 40 hours apart over 10-18 days. Three dose levels: 40Gy and 45Gy all in 5 fractions. Each initial dose level will have 6 participants allocated to them. All participants are assessed at their 3 month post SBRT visit for Dose-Limiting Toxicities (DLTs). If ≤1 participant experiences a DLT, participants will be enrolled at the next dose level. If ≥3 participants experience a DLT, further accrual will be permanently halted and the study stopped. If 2 participants experience a DLT, then an additional 6 participants will be enrolled at the same dose level. In this setting, if ≤ 3/12 participants have a DLT, participants will be enrolled at the next dose level. If ≥ 4/12 participants have a DLT, further accrual will be permanently halted and the study stopped and 35 Gy will not be recommended as safe. The dosing strategy for the 2nd (45Gy) cohort will be identical to the first.
