Study Arms:
- Arm I (curcumin) (Type: EXPERIMENTAL): Patients undergo radiation therapy 5 days a week for a total of 28 fractions. Patients also receive capecitabine PO BID on the days of radiation therapy and curcumin PO BID in weeks 1-11.5.
- Arm II (placebo) (Type: ACTIVE_COMPARATOR): Patients undergo radiation therapy and receive capecitabine as in Arm I. Patients also receive placebo PO BID in weeks 1-11.5.

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

Answer: outcome: terminate
termination_type: lack of efficacy
