Time frame
From randomization to last follow-up. Analysis was to occur after 180 deaths were reported. Analysis occurred after 133 deaths were reported. Maximum follow-up at time of analysis was 6.5 years.

What was measured

NIH-required analysis. An event for overall survival is death due to any cause. Survival time is defined as time from randomization to the date of death or last known follow-up (censored). Rates are estimated by the Kaplan-Meier method. The protocol endpoint is hazard ratio, which is reported in the statistical analysis results. Five-year rate is reported simply as summary data; it is not the outcome measure.

Analysis population: Eligible participants. Data were stratified by ethnicity.

Groups in this outcome

IMRT + Cisplatin

Intensity-modulated radiotherapy (IMRT) with concurrent cisplatin Cisplatin: 100 mg/m2 IV on days 1 and 22 of IMRT IMRT: 35 fractions over 6 weeks, 6 fractions per week, 2 Gray per fraction to total dose of 70 Gy.

IMRT + Cetuximab

Intensity-modulated radiotherapy (IMRT) with concurrent cetuximab Cetuximab: 400 mg/m2 IV 5-7 days before IMRT then 250 mg/m2 IV weekly for 7 weeks IMRT: 35 fractions over 6 weeks, 6 fractions per week, 2 Gray per fraction to total dose of 70 Gy.
