- Time frame
- From step 2 randomization (chemotherapy vs. chemotherapy followed by chemoradiation) to the date of death or last follow-up. Maximum follow-up at time of the phase III analysis was 12.8 years, measured from step 2 randomization.
What was measured
NIH-required analysis. Overall survival (OS) is estimated by the Kaplan-Meier method. Survival time is measured from step 2 randomization to date of death from any cause or last known follow-up (censored). Analysis was to occur at the earlier of 316 reported deaths or when all patients have five years potential follow-up from step 2 randomization.
Analysis population: Participants randomized at step 2. Data were stratified by ethnicity.
Groups in this outcome
Arm III (Chemotherapy)
Patients receive the same treatment as in arm I or arm II for one month. Patients undergo CT, MRI, and/or x-ray imaging throughout the trial. Patients also undergo blood sample collection during screening and follow-up and undergo tissue sample collection at baseline.
Arm IV (Chemotherapy, Chemoradiotherapy)
Patients receive the same treatment as in arm I or arm II for one month. Beginning within 7-21 days after completion of chemotherapy, patients undergo radiotherapy (RT) (3-dimensional conformal radiotherapy or intensity modulated radiotherapy) 5 days per week for 5.5 weeks (28 fractions). During radiotherapy, patients receive either capecitabine PO BID 5 days per week or fluorouracil IV continuously for 5.5 weeks or until radiotherapy is completed. Patients undergo CT, MRI, and/or x-ray imaging throughout the trial. Patients also undergo blood sample collection during screening and follow-up and undergo tissue sample collection at baseline.
