Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Cumulative Radiation Dose at Which Severe Oral Mucositis (World Health Organization [WHO] Score ≥ 3) Was First Observed | 8 weeks | The primary endpoint planned in the protocol was the percentage of participants with an oral mucositis score greater than or equal to 3 using the WHO oral mucositis severity scale at a cumulative radiation dose of 50 Gy. This was modified by protocol amendment to the cumulative radiation dose at which a WHO score greater than or equal to 3 was first observed. This change was made to account for the fact that in real practice most patients receive a cumulative dose between 60 and 70 Gy. The presence of grade 3 or 4 oral mucositis was assessed twice weekly during the active phase (radiotherapy) by a trained radiation oncologist or an ear nose and throat specialist who took into account the field of radiation treatment. WHO score 3 = oral ulcers, liquid diet only; WHO score 4 = oral alimentation impossible. Each assessment was associated with the actual cumulative dose of radiotherapy. |

The WHO scores were as follows: 0 = None; 1 = oral soreness, erythema; 2 = oral erythema, ulcers, solid diet tolerated; 3 = oral ulcers, liquid diet only; 4 = oral alimentation impossible. The maximum severity was the maximum score reported during the active phase. |

Outcome results
Cumulative Radiation Dose at Which Severe Oral Mucositis (World Health Organization [WHO] Score ≥ 3) Was First Observed
The primary endpoint planned in the protocol was the percentage of participants with an oral mucositis score greater than or equal to 3 using the WHO oral mucositis severity scale at a cumulative radiation dose of 50 Gy. This was modified by protocol amendment to the cumulative radiation dose at which a WHO score greater than or equal to 3 was first observed. This change was made to account for the fact that in real practice most patients receive a cumulative dose between 60 and 70 Gy. The presence of grade 3 or 4 oral mucositis was assessed twice weekly during the active phase (radiotherapy) by a trained radiation oncologist or an ear nose and throat specialist who took into account the field of radiation treatment. WHO score 3 = oral ulcers, liquid diet only; WHO score 4 = oral alimentation impossible. Each assessment was associated with the actual cumulative dose of radiotherapy.
Time frame: 8 weeks
