Study Arms:
- Capecitabine + PEG-interferon alfa-2a (Type: EXPERIMENTAL): Capecitabine 1000 mg/m2 orally twice daily during the first 14 days of each 3-week cycle (2 weeks on, 1 week rest), and PEG-interferon alfa-2a subcutaneously beginning at 180 mcg per week for 21 days.

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