PRIMARY outcome

Timeframe: Up to 11 weeks (assessed at the time of post-treatment surgery)

Population: Participants with available data.

Pathological complete response was defined as the absence of viable tumor cells in the tumor specimen, including regional lymph nodes determined with standard histological procedures.

Capecitabine 825 mg/m\^2 orally twice daily plus standard radiotherapy for 5 weeks as prescribed according to normal clinical practice, followed by surgery within 6 weeks after completion of treatment.
Percentage of Participants With Pathological Complete Response
16 percentage of participants

SECONDARY outcome

Timeframe: Up to 11 weeks (assessed 4-6 weeks after the completion of radiochemotherapy)

Population: Participants with available data.

Complete response was defined as the disappearance of all target and non-target lesions. Partial remission was defined as ≥ 30% decrease in the sum of the longest diameter (SLD) of target lesions, taking as reference the baseline SLD, or the persistence of 1 or more non-target lesions. No response to treatment was defined as neither sufficient shrinkage to qualify for partial remission nor sufficient increase to qualify for progressive disease, compared to the baseline SLD.
