Study Arms:
- Arm I (Type: EXPERIMENTAL): Patients receive single-fraction radiotherapy (8 Gy) on day 1.
- Arm II (Type: ACTIVE_COMPARATOR): Patients receive multiple-fraction radiotherapy (to a total of 20 Gy) over 5 days or over 8 days if re-irradiation of the spine and/or whole pelvis is involved AND prior initial radiotherapy was given in multiple fractions.

Based on this trial design, predict the completion outcome and termination type (if applicable).
