Overview
Radiation oropharyngeal mucositis is one of the most painful side effects of radiotherapy in patients with head and neck tumors. However, the traditional radioactive oropharyngeal mucositis grading system has the problem of poor evaluation consistency. To solve this problem, we innovatively classify radiation oropharyngeal mucositis into four types according to the four-stage histopathological changes of acute radiation injury: (1) congestive; (2) Scattered erosion type; (3) Fusion erosion type; (4) Ulcer type. We intend to conduct a multicenter observational cohort study to compare the consistency of different physicians in the assessment of radiation oropharyngeal mucositis with new and traditional classifications, and to explore changes in blood markers of different types of oropharyngeal mucositis using clinical residual blood samples.
Description
Since this is an observational study, no additional visits, laboratory analyses, or evaluations beyond the routine clinical practice requirements are necessary. Patients must sign the latest informed consent form (ICF) approved by the ethics committee before data collection is carried out. After obtaining the patient's consent, clinical routine diagnosis and treatment information will be collected.
The study is divided into three parts. The first part compares the consistency of results among different methods used to assess mucositis. The research process involves having different doctors assess the same patient at the same stage using a specific grading method three times, and taking the results of more than two of these assessments as the internal unified results of that grading method (each patient can be assessed and data recorded every 1-2 weeks during radiotherapy). After obtaining the internal unified results of the three mucositis grading methods, the consistency of results among different methods used for assessment is compared.
The second part first determines the internal consistency of doctor evaluations for four methods (the traditional three mucositis grading methods and the new classification method), and then uses the consistency results of each method to compare the stability of the assessments. The research process involves having different doctors assess the same patient at the same stage using a specific method three times. Each patient can be assessed and data recorded every 1-2 weeks during radiotherapy. The consistency of evaluations among different doctors for this method is obtained. Finally, this consistency is used to compare the stability of the assessments between different methods.
The third part compares the consistency of results between the assessment using the new mucositis classification method and the patient's self-assessment. The research process involves having different doctors assess the same patient at the same stage using the new classification method three times, and taking the results of more than two of these assessments as the internal unified result of the new classification method (each patient can be assessed and data recorded every 1-2 weeks during radiotherapy). After obtaining the internal unified results of the new classification method and the patient's self-assessment results, the consistency of results between using the new classification method and the patient's self-assessment is compared.
