研究目的: |
1、建立融合影像组学、剂量组学、DVH参数与临床因素的预测模型,提高放疗口腔黏膜炎预测的准确性与前瞻性。 2、探索影响放疗相关口腔黏膜损伤发生与严重程度的多维特征组合与机制。 3、为鼻咽癌放疗患者个体化治疗提供预测依据与干预可能性。 |

|
Objectives of Study: |
1.Establish a predictive model integrating radiomics, dosiomics, DVH parameters, and clinical factors to enhance the accuracy and predictability of radiotherapy-induced oral mucositis. 2.Explore the multi-dimensional feature combinations and mechanisms influencing the occurrence and severity of radiotherapy-related oral mucosal damage. 3.Provide predictive evidence and intervention possibilities for individualized treatment of nasopharyngeal carcinoma patients undergoing radiotherapy. |

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
一、数据采集方式 1、所有数据通过医院放疗中心的常规流程获取,包括电子病历系统(EMR)、放疗计划系统(TPS,含CT影像、剂量分布、DVH参数)和随访表格。 2、临床资料(如年龄、性别、TNM分期、治疗方式、用药情况等)由研究人员从病历系统中提取。 3、影像组学、剂量组学等数据由工程师通过标准化DICOM文件导出并处理。 4、口腔黏膜炎分级由2名高年资医师独立评估,必要时由第三名研究者裁决。 二、数据录入与存储 1、所有数据统一录入到建立的专用数据库,采用双人核对原则,确保录入准确性。 2、数据格式为电子化(如Excel、SPSS、SQL数据库),存放于医院加密服务器。 3、原始纸质随访表、知情同意书等资料由专人保管,存放于科研资料档案柜内。 三、数据质量控制 1、研究启动前统一培训研究人员,确保数据收集和录入规范。 2、每季度进行一次数据抽查与质量核查,发现问题及时修正。 3、剔除缺失>30%的样本;对部分缺失值采用多重插补法。 四、数据保密与权限管理 1、患者数据均进行脱敏处理,使用唯一研究编码代替姓名和住院号。 2、数据仅限研究团队成员使用,不得外传。 3、成果公开发表时不涉及任何可识别的个人隐私。 4、项目结束后,原始数据和分析数据将加密存档至少5年。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
I. Data Collection Methods 1.All data will be obtained through the routine workflows of the hospital’s radiotherapy center, including the electronic medical record system (EMR), treatment planning system (TPS, including CT images, dose distribution, and DVH parameters), and follow-up forms. 2.Clinical data (e.g., age, sex, TNM stage, treatment modality, medication history) will be extracted from the medical record system by the research staff. 3.Radiomics and dosiomics data will be exported and processed by engineers using standardized DICOM files. 4.Oral mucositis grading will be independently assessed by two senior physicians, with adjudication by a third investigator if discrepancies occur. II. Data Entry and Storage 1.All data will be uniformly entered into a dedicated research database, using a double-entry verification principle to ensure accuracy. 2.Data will be stored in electronic formats (e.g., Excel, SPSS, SQL database) on encrypted hospital servers. 3.Original paper follow-up forms, informed consent documents, and related records will be securely stored in research archives under the custody of designated personnel. III. Data Quality Control 1.Prior to study initiation, all research personnel will undergo standardized training to ensure consistent data collection and entry procedures. 2.Data will be randomly audited and quality-checked on a quarterly basis; any identified issues will be promptly corrected. 3.Samples with more than 30% missing data will be excluded; multiple imputation will be applied for partially missing values. IV. Data Confidentiality and Access Management 1.All patient data will be de-identified, with unique study codes replacing names and medical record numbers. 2.Data access will be restricted to members of the research team and will not be shared externally. 3.Publications will not contain any personally identifiable information. 4.Upon study completion, raw and processed data will be encrypted and archived for at least five years. |
