- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- Carbon ion radiotherapy (Type: EXPERIMENTAL): Carbon ion radiotherapy will be administered 5 days each week (Monday-Friday). The prescription dose will be 60 GyE in 20 fractions, to be delivered over four weeks.
- Routine standard of care (Type: ACTIVE_COMPARATOR): Subjects on the control arm will not receive upfront radiotherapy but may receive radiotherapy (not carbon ion radiotherapy) if disease progression occurs.

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