研究目的:

(一)主要研究目的 本研究旨在通过多中心、前瞻性队列研究设计,评估基于宫颈细胞学样本中DNA甲基化标志物(CISENDO检测)在筛查和随访子宫内膜病变中的诊断效能。主要研究终点为子宫内膜不典型增生(EIN)或子宫内膜侵袭性癌的确诊情况,以验证该分子标志物在识别高危病变中的敏感性与特异性。 (二)次要研究目的 (1)评估DNA甲基化水平在子宫内膜病变进展或消退过程中的动态变化,探索其作为疾病随访监测标志物的可行性; (2)比较不同筛查策略(如甲基化检测与传统病理检查)在临床实践中的适用性与准确性; (3)探索DNA甲基化标志物在不同风险分层人群中的表达差异,为个体化筛查与随访策略提供依据; (4)推动宫颈细胞学样本作为微创检测来源在子宫内膜病变筛查中的临床应用转化。  

Objectives of Study:

(I) Primary Research Objective This multicenter, prospective cohort study aims to evaluate the diagnostic performance of DNA methylation markers (the CISENDO assay) in cervical cytology samples for the screening and follow-up of endometrial lesions. The primary endpoint is the confirmed diagnosis of endometrial intraepithelial neoplasia (EIN) or invasive endometrial carcinoma, with the goal of validating the sensitivity and specificity of this molecular marker in identifying high-risk lesions. (II) Secondary Research Objectives (1) To assess the dynamic changes in DNA methylation levels during the progression or regression of endometrial lesions and explore its feasibility as a biomarker for disease monitoring. (2) To compare the applicability and accuracy of different screening strategies (e.g., methylation testing versus traditional pathological examination) in clinical practice. (3) To investigate the differential expression of DNA methylation markers among populations with varying risk stratifications, providing a basis for personalized screening and follow-up strategies. (4) To promote the clinical translation and application of cervical cytology samples as a minimally invasive source for endometrial lesion screening.

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:

数据采集: 1. 采集内容: 患者基本信息与临床资料: 人口学特征(年龄、身高、体重)、病史(内膜病变史、糖尿病、高血压、PCOS等)、临床症状(异常子宫出血、绝经后出血等)、高危因素状态。 检测指标数据: 金标准: 宫腔镜及组织病理学诊断结果(包括病变类型、分级等)。 指标试验: CISENDO检测的DNA甲基化相对数值。 辅助检查: 经阴道超声结果(内膜厚度、占位、血流)、既往HPV/TCT结果(如有)、血清CA125水平(如有)。 随访数据: 随访时间点、随访时的CISENDO检测结果、后续宫腔镜及病理结果、疾病状态变化(进展/消退)、治疗情况、随访终止原因。 2. 采集工具与流程: 工具: 采用统一的电子病例报告表(Electronic Case Report Form, eCRF)。 流程: 由各研究中心经过培训的研究人员,在患者入组基线及每次随访时,将上述数据录入eCRF。 数据来源于患者的病历记录、实验室报告单和病理报告。 数据管理: 1. 数据库与安全: 专用数据库: 建立专用、加密的研究数据库集中存储所有eCRF数据。 权限控制: 设置严格的访问权限,确保只有授权的研究人员可以访问。 数据备份: 定期进行数据备份,防止数据丢失。 2. 质量控制: 录入质控: 数据由研究人员双人独立录入,并进行逻辑核对与一致性检查。 数据核查: 设立数据核查机制,对缺失、异常或存在逻辑错误的数据进行溯源查询和修正。 培训与一致性: 研究启动前对各中心人员进行统一培训,确保数据采集的标准化。 3. 保密与隐私保护: 去标识化: 研究数据库中的患者信息采用唯一研究编号,不直接使用可识别个人身份的信息。 责任归属: 包含患者个人信息的原始资料(如知情同意书)由研究负责人(李雷) 统一保管。 合规性: 整个数据管理过程严格遵守《赫尔辛基宣言》、中国相关法规及伦理委员会的要求。 4. 数据分析与保存: 分析准备: 经清理和核对后的锁定数据库将用于最终的统计分析。 长期保存: 研究结束后,所有研究数据(包括数据库和原始资料)将按照资助单位和管理机构的规定,在负责单位进行长期保密存档。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data Collection: Study data, including patient demographics, clinical history, symptom profiles, results of the index test (CISENDO DNA methylation values), reference standard (histopathology), imaging findings (transvaginal ultrasound), and follow-up information, will be recorded using a standardized Electronic Case Report Form (eCRF) at each participating center.Data Management: A dedicated, encrypted research database will be established for centralized data storage. Data quality will be ensured through double independent entry and logical checks. Patient privacy will be protected via de-identification (using unique study IDs) and strict access controls. All identifiable records will be kept confidential by the principal investigator. Data management will comply with the Declaration of Helsinki and ethical committee regulations.
