Time frame
From start of treatment until 434 failures have occurred, approximately 5 years from start of study. (Patients are followed until death or study termination, whichever occurs first.)

What was measured

Grade 3 or higher Common Terminology Criteria for Adverse Events (CTCAE) version 3.0 radiation mucositis definitely, probably, or possibly related to protocol treatment. Grade refers to the severity of the AE. The CTCAE v3.0 assigns Grades 1 through 5 with unique clinical descriptions of severity for each AE based on this general guideline: Grade 1 Mild AE, Grade 2 Moderate AE, Grade 3 Severe AE, Grade 4 Life-threatening or disabling AE, Grade 5 Death related to AE.

Analysis population: Randomized eligible patients with follow-up data

Groups in this outcome

RT + Cisplatin

Radiation therapy (RT) as accelerated fractionation by concomitant boost (AFX-CB) or intensity-modulated radiation therapy (IMRT) plus cisplatin

RT + Cisplatin + Cetuximab

Radiation therapy (RT) as accelerated fractionation by concomitant boost (AFX-CB) or intensity-modulated radiation therapy (IMRT) plus cisplatin plus cetuximab

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
