|---|---|---|---|
| Primary | Overall Survival (Percentage of Participants Alive) | From randomization to last follow-up. Follow-up schedule from end of treatment: 6-8 weeks, every 3 mo. for 2 yr., then every 6 mo. for 3 yr., then yearly. Maximum follow-up at time of analysis was 6.5 years. Three-year rates are reported here. | Overall survival time is defined as time from randomization to the date of death (failure) or last known follow-up (censored). Overall survival rates are estimated by the Kaplan-Meier method. The full distribution is the outcome of interest, and the protocol specifies that the distributions of failure times be compared between the arms, which is reported in the statistical analysis results. Three-year estimates are provided as a summary of the distributions. Analysis was planned to occur after 309 deaths had been reported. |
| Secondary | Local-regional Failure (Percentage of Participants With Local-regional Failure) | From randomization to last follow-up. Follow-up schedule from end of treatment: 6-8 weeks, every 3 mo. for 2 yr., then every 6 mo. for 3 yr., then yearly. Maximum follow-up at time of analysis was 6.5 years. Three-year rates are reported here. | Local-regional failure time is defined as time from randomization to persistent disease in the primary tumor or regional nodes (considered an event at day 1), relapse/progression in either of those sites (considered an event at the time of relapse/progression), death (competing event), or last follow-up (censored). Progression is defined as an estimated increase in the size of the tumor of greater than 25% or appearance of new areas of malignant disease. The full distribution is the outcome of interest, and the protocol specifies that the distributions of failure times be compared between the arms, which is reported in the statistical analysis results. Three-year estimates are provided as a summary of the distributions. Analysis was planned to occur after 309 deaths had been reported. |
| Secondary | Local-regional Failure (Alternate Definition) [Percentage of Participants With Local-regional Failure] | From randomization to last follow-up. Follow-up schedule from end of treatment: 6-8 weeks, every 3 mo. for 2 yr., then every 6 mo. for 3 yr., then yearly. Maximum follow-up at time of analysis was 6.5 years. Three-year rates are reported here. | Local-regional failure time is defined as time from randomization to relapse/progression in the primary tumor or regional nodes (event), death due to study cancer or unknown causes (event), death due to other causes (competing event), distant metastasis (competing event), or last follow-up (censored). Progression is defined as an estimated increase in the size of the tumor of greater than 25% or appearance of new areas of malignant disease. The full distribution is the outcome of interest, and the protocol specifies that the distributions of failure times be compared between the arms, which is reported in the statistical analysis results. Three-year estimates are provided as a summary of the distributions. Analysis was planned to occur after 309 deaths had been reported. |
| Secondary | Disease-free Survival (Percentage of Participants Alive Without Disease) | From randomization to last follow-up. Follow-up schedule from end of treatment: 6-8 weeks, every 3 mo. for 2 yr., then every 6 mo. for 3 yr., then yearly. Maximum follow-up at time of analysis was 6.5 years. Three-year rates are reported here. | Disease-free survival time is defined as time from randomization to persistent disease in the primary tumor or regional nodes (considered an event at day 1), relapse/progression in either of those sites (considered an event at the time of relapse/progression), distant metastasis (event), second primary tumor (event), death (event), or last follow-up (censored). Progression is defined as an estimated increase in the size of the tumor of greater than 25% or appearance of new areas of malignant disease. The full distribution is the outcome of interest, and the protocol specifies that the distributions of failure times be compared between the arms, which is reported in the statistical analysis results. Three-year estimates are provided as a summary of the distributions. Analysis was planned to occur after 309 deaths had been reported. |
| Secondary | Progression-free Survival (Alternate Definition of Disease-free Survival) [Percentage of Participants Alive Without Progression] | From randomization to last follow-up. Follow-up schedule from end of treatment: 6-8 weeks, every 3 mo. for 2 yr., then every 6 mo. for 3 yr., then yearly. Maximum follow-up at time of analysis was 6.5 years. Three-year rates are reported here. | Progression-free survival time is defined as time from randomization to relapse/progression in the primary site or regional nodes (event), distant metastasis (event), death (event), or last follow-up (censored). Progression is defined as an estimated increase in the size of the tumor of greater than 25% or appearance of new areas of malignant disease. The full distribution is the outcome of interest, and the protocol specifies that the distributions of failure times be compared between the arms, which is reported in the statistical analysis results. Three-year estimates are provided as a summary of the distributions. Analysis was planned to occur after 309 deaths had been reported. |
| Secondary | Percentage of Participants With Toxicity Grade 3 or Higher | From randomization to last follow-up. Follow-up schedule from end of treatment: 6-8 weeks, every 3 mo. for 2 yr., then every 6 mo. for 3 yr., then yearly. Maximum follow-up at time of analysis was 6.5 years. | Acute radiation therapy toxicities (within 90 days from start of radiation therapy) and systemic effects at any time were scored using Common Toxicity Criteria (CTC) version 2.0. Late RT toxicities (\> 90 days from start of radiation therapy) were scored by the Radiation Therapy Oncology Group (RTOG)/European Organisation for. Research and Treatment of Cancer (EORTC) criteria. Both criteria grades toxicity severity from 1=mild to 5=death. Summary data is provided in this outcome measure; see Adverse Events Module for specific adverse event/toxicity data. |
| Secondary | Performance Status Scale for Head and Neck Cancer (PSS-HN) Normalcy of Diet Score - Area Under the Curve (AUC) at One Year | Baseline (pretreatment), sometime during the last two weeks of treatment, three months from start of treatment, and one year from start of treatment. | The PSS-HN is a clinician-rated evaluation conducted as an unstructured interview format that assesses three functions: Normalcy of Diet (this outcome measure), Public Eating, and Understandability of Speech. Each function is scored from 0 to 100 and analyzed separately. Higher scores indicate better performance status. Treatment effect was analyzed as time-weighted average between baseline (pre-treatment) and one year calculated by use of area under the curve (AUC). |
| Secondary | PSS-HN Public Eating Score - AUC at One Year | Baseline (pretreatment), sometime during the last two weeks of treatment, three months from start of treatment, and one year from start of treatment. | The Performance Status Scale for Head and Neck Cancer (PSS-HN) is a clinician-rated evaluation conducted as an unstructured interview format that assesses three functions: Normalcy of Diet , Public Eating (this outcome measure), and Understandability of Speech. Each function is scored from 0 to 100 and analyzed separately. Higher scores indicate better performance status. Treatment effect was analyzed as time-weighted average between baseline (pretreatment) and one year calculated by use of area under the curve (AUC). |
| Secondary | PSS-HN Understandability of Speech Score - AUC at One Year | Baseline (pretreatment), sometime during the last two weeks of treatment, three months from start of treatment, and one year from start of treatment. | The Performance Status Scale for Head and Neck Cancer (PSS-HN) is a clinician-rated evaluation conducted as an unstructured interview format that assesses three functions: Normalcy of Diet , Public Eating, and Understandability of Speech (this outcome measure).

| Secondary | Head and Neck Radiotherapy Questionnaire (HNRQ) - AUC at One Year | Baseline (pretreatment), sometime during the last two weeks of treatment, three months from start of treatment, and one year from start of treatment. | The HNRQ is a patient-reported questionnaire administrated through a paper format; it measures radiation-related side effects and the overall well-being of head and neck cancer patients in the past week. The overall score is the mean of the 22 questions, with a range of 1 to 7. Higher scores indicate better quality of life. Treatment effect was analyzed as time-weighted average between baseline (pre-treatment) and 1 year calculated by use of area under the curve (AUC). |
| Secondary | Correlation of Epidermal Growth Factor Receptor(EGFR) With Outcomes | From randomization to date of death or last follow-up | |
| Secondary | Correlation of COX-2 With Outcomes | From randomization to date of death or last follow-up |
