研究目的: |
本研究为单中心、回顾性队列研究,拟依托中山大学孙逸仙纪念医院逸仙大数据平台及PACS影像系统,连续检索并纳入具有完整临床资料、治疗信息、基线MRI影像及随访信息的鼻咽癌患者。研究首先在N+人群中评估单纯淋巴结坏死(lymph node necrosis,LNN)与远处转移无生存(distant metastasis-free survival,DMFS)的关系;随后聚焦LNN阳性患者,分析坏死淋巴结表型特征与预后的关联;最终在AJCC第9版N3期患者中构建坏死淋巴结表型评分(necrotic nodal phenotype score,NNPS),将N3患者进一步分为N3a(无LNN或低危LNN)和N3b(高危LNN)两组,评价其DMFS差异。 主要终点为DMFS;次要终点包括总生存(overall survival,OS)、无病生存(disease-free survival,DFS)和局部/区域复发相关终点(如资料完整则纳入分析)。计划纳入我院可追溯病例约810例,最终样本量以满足入排标准且影像资料完整者为准。主要统计方法包括Kaplan-Meier法、log-rank检验、Cox比例风险模型、相关性分析、预设评分分层分析及landmark敏感性分析。landmark时间点定义为研究样本中“诊断至放疗结束”的平均时长。 |

Objectives of Study: |
This study is a single-center, retrospective cohort study. Using the Sun Yat-sen Memorial Hospital Big Data Platform and the PACS imaging system, patients with nasopharyngeal carcinoma who have complete clinical data, treatment information, baseline MRI imaging, and follow-up data will be continuously searched and enrolled. Initially, the study will evaluate the association between isolated lymph node necrosis (LNN) and distant metastasis-free survival (DMFS) in the N+ population. Subsequently, focusing on LNN-positive patients, the relationship between necrotic lymph node phenotypic characteristics and prognosis will be analyzed. Finally, a necrotic nodal phenotype score (NNPS) will be constructed for patients staged as N3 according to the 9th edition of the AJCC staging system. This will allow further stratification of N3 patients into N3a (no LNN or low-risk LNN) and N3b (high-risk LNN) groups, and the differences in DMFS between these groups will be evaluated.The primary endpoint is DMFS. Secondary endpoints include overall survival (OS), disease-free survival (DFS), and locoregional recurrence-related endpoints (to be included in the analysis if data are complete). The study aims to include approximately 810 eligible cases from our hospital, with the final sample size determined by those meeting the inclusion and exclusion criteria and having complete imaging data. Primary statistical methods include the Kaplan-Meier method, log-rank test, Cox proportional hazards mode |

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: |
1.病例报告表/电子数据记录:本研究使用预设的电子病例报告表(eCRF)收集资料。eCRF内容包括:人口学信息、病理及分期信息、治疗信息(放疗、化疗等)、实验室指标(含EBV DNA,如可获取)、影像学变量(LNN有无、ENE分级、坏死淋巴结个数、单双侧分布、多区域受累、咽后坏死、下颈坏死、跳跃坏死等)以及随访结局信息。所有变量定义、编码规则及缺失值处理原则将在数据字典中预先明确。 2 数据管理:研究数据主要来源于医院电子病历系统、逸仙大数据平台和PACS影像系统,采用电子方式采集并录入数据库。研究团队将建立去标识化研究数据库,使用唯一研究编号替代患者身份信息。数据管理包括:1)双人核对关键变量;2)逻辑核查、范围核查和缺失核查;3)对关键影像变量和结局变量进行抽样复核;4)记录数据清理和修改痕迹。数据库经核查确认后方可锁库,锁库后如需修改必须经项目负责人批准并保留审计轨迹。研究原始数据、分析数据集和统计程序将分别保存于受控服务器或加密存储介质,仅限授权研究人员访问。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
1. Case Report Form / Electronic Data RecordingThis study uses a predefined electronic case report form (eCRF) for data collection. The eCRF includes demographic information, pathological and staging information, treatment information (radiotherapy, chemotherapy, etc.), laboratory indicators (including EBV DNA, if available), imaging variables (presence or absence of LNN, ENE grade, number of necrotic lymph nodes, unilateral or bilateral distribution, involvement of multiple regions, retropharyngeal necrosis, lower neck necrosis, skip necrosis, etc.), and follow-up outcome information. All variable definitions, coding rules, and principles for handling missing data will be predefined in a data dictionary.2. Data ManagementStudy data are primarily sourced from the hospital’s electronic medical record system, the Sun Yat-sen Memorial Hospital Big Data Platform, and the PACS imaging system. Data will be collected electronically and entered into a database. The research team will establish a de-identified research database, replacing patient identity information with a unique study ID. Data management procedures include:Double-checking of key variables by two individuals;Logical verification, range verification, and missing data verification;Sampling-based review of key imaging variables and outcome variables;Documentation of data cleaning and modification trails.The database will be locked only after verification and confirmation. If modifications are required after database locking, approval from the principal investigator must be obtained, and an audit trail will be preserved. Original research data, analysis datasets, and statistical programs will be stored separately on a controlled server or encrypted storage media, with access restricted to authorized research personnel. |
