O que o estudo está medindo?

Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
Incidence of Severe Radiation-Induced Oral Mucositis
Prazo: From the start of radiotherapy to 4 weeks after completion of radiotherapy
The incidence of Grade ≥3 radiation-induced oral mucositis (RIOM) in the experimental and control groups, as assessed using the Radiation Therapy Oncology Group (RTOG) acute RIOM grading scale.
From the start of radiotherapy to 4 weeks after completion of radiotherapy

Medidas de resultados secundários

Medida de resultado
Descrição da medida
Prazo
Onset Time of Severe Radiation-Induced Oral Mucositis
Prazo: From the start of radiotherapy to 4 weeks after completion of radiotherapy
The interval from the start of radiotherapy to the first occurrence of severe radiation-induced oral mucositis (RIOM). Severe RIOM is defined as Grade ≥3 according to the Radiation Therapy Oncology Group (RTOG) acute RIOM grading scale.
From the start of radiotherapy to 4 weeks after completion of radiotherapy
Duration of Severe Radiation-Induced Oral Mucositis
Prazo: From the start of radiotherapy to 4 weeks after completion of radiotherapy.
The interval from the first occurrence of severe acute radiation-induced oral mucositis (RIOM) to its resolution to Grade ≤2, as assessed according to the Radiation Therapy Oncology Group (RTOG) acute RIOM grading scale. Severe RIOM is defined as Grade ≥3 on the RTOG acute RIOM grading scale.
From the start of radiotherapy to 4 weeks after completion of radiotherapy.
Recovery Rate of Severe Radiation-Induced Oral Mucositis
Prazo: From the start of radiotherapy to 4 weeks after completion of radiotherapy
The proportion of patients whose severe acute radiation-induced oral mucositis (RIOM) resolves to Grade ≤2 during the overall observation period, as assessed according to the Radiation Therapy Oncology Group (RTOG) acute RIOM grading scale. Severe RIOM is defined as Grade ≥3 on the RTOG acute RIOM grading scale.
From the start of radiotherapy to 4 weeks after completion of radiotherapy
Incidence of Radiation-Induced Oral Mucositis
Prazo: From the start of radiotherapy to 4 weeks after completion of radiotherapy
The proportion of patients who develop any-grade acute radiation-induced oral mucositis (RIOM) (Grade ≥1) during the overall observation period, as assessed according to the Radiation Therapy Oncology Group (RTOG) acute RIOM grading scale.
From the start of radiotherapy to 4 weeks after completion of radiotherapy
Incidence of Radiotherapy Interruption
Prazo: From the start of radiotherapy through completion of radiotherapy, an average of 7 weeks.
The proportion of patients who experience a radiotherapy interruption of 5 or more consecutive days during the radiotherapy period due to acute radiation-induced oral mucositis (RIOM) or other related adverse events.
From the start of radiotherapy through completion of radiotherapy, an average of 7 weeks.
Quality of life (QoL)
Prazo: From the start of radiotherapy to 4 weeks after completion of radiotherapy
Quality of life related to head and neck symptoms will be assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Head and Neck Module (EORTC QLQ-H&N35), version 1.0. This questionnaire comprises 35 items, including seven multi-item scales and 11 single-item measures. All scales and items will be scored according to the official EORTC Scoring Manual and linearly transformed to a 0 to 100 scale, with higher scores indicating greater symptom burden and poorer quality of life.
From the start of radiotherapy to 4 weeks after completion of radiotherapy
Numeric Rating Scale for Pain
Prazo: From the start of radiotherapy to 4 weeks after completion of radiotherapy
Oral mucositis-related pain was assessed in all participants using the Numeric Rating Scale (NRS), an 11-point scale ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst pain imaginable. Higher scores indicate worse pain.
From the start of radiotherapy to 4 weeks after completion of radiotherapy
Safety as Assessed by CTCAE
Prazo: From the start of radiotherapy to 4 weeks after completion of radiotherapy
Adverse events were monitored and recorded according to the Common Terminology Criteria for Adverse Events (CTCAE), version 5.0
From the start of radiotherapy to 4 weeks after completion of radiotherapy
