- 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
An event for progression-free survival is local, regional, or distant disease progression or death due to any cause. Progression-free survival time is defined as time from randomization to the date of progression/death or last known follow-up (censored). Rates are estimated by the Kaplan-Meier method. The protocol endpoint is the distribution of progression-free survival times, for which the hazard ratio 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
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.
