研究目的:

本研究拟针对围绝经期及绝经后宫颈高级别鳞状上皮内病变(HSIL)患者,开展一项单中心回顾性队列研究,旨在系统分析宫颈锥切术后切缘阳性的独立危险因素,并构建基于常规临床变量的预测模型。具体研究目的如下: 一、主要目的 1. 识别切缘阳性的独立危险因素 2. 构建切缘阳性的列线图预测模型 3. 内部验证预测模型的性能 二、次要目的 1. 比较不同手术方式(LEEP vs. CKC)对切缘状态的影响 2. 评估绝经年限对切缘阳性的影响 3. 为临床术前风险评估和术后随访策略提供循证依据  

Objectives of Study:

This study will conduct a single-center, retrospective cohort analysis of perimenopausal and postmenopausal patients diagnosed with cervical high-grade squamous intraepithelial lesion (HSIL). The primary aim is to identify independent clinical risk factors associated with positive surgical margins following cervical conization and to develop and internally validate a clinically applicable nomogram prediction model based on routinely available preoperative variables. Findings are intended to inform evidence-based preoperative risk stratification and postoperative surveillance strategies. Specific objectives are structured as follows: Primary Objectives: 1. To identify independent predictors of positive surgical margins after cervical conization; 2. To develop a nomogram-based prediction model for positive surgical margins using routinely collected clinical variables; 3. To perform internal validation of the model’s discrimination, calibration, and clinical utility. Secondary Objectives: 1. To compare the association between surgical technique LEEP versus CKC and margin status; 2. To assess the impact of menopausal duration on the likelihood of positive surgical margins; 3. To provide actionable, evidence-based recommendations to guide individualized preoperative counseling and postoperative follow-up protocols.

共享原始数据的方式(说明:请填入公开原始数据日期和方式,如采用网络平台,需填该网络平台名称和网址):

原始数据将自研究结果发表后6个月起,在合理请求下通过通讯作者共享。请求需说明数据使用目的,并经本单位伦理委员会批准。数据将仅用于非商业性学术研究,请求者可签署数据使用协议。去标识化后的个体数据(不含可直接识别患者身份的信息)、数据字典及统计分析代码将以补充材料形式随论文发表,或在Figshare(https://figshare.com)等公开数据平台存档。具体网址将在论文发表后更新。

The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url):

Individual participant data (de-identified, without direct identifiers) will be available upon reasonable request from the corresponding author starting 6 months after publication of the main results.

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:

本研究为回顾性研究,数据来源于武汉市第四医院的电子病历系统(HIS)、检验信息系统(LIS)及病理信息系统。 病例记录表(CRF):?研究者将设计标准化的电子数据提取表(Microsoft Excel格式),包含以下变量:①人口学指标(年龄、绝经年限、体重指数、吸烟史);②临床指标(高血压、糖尿病);③术前检查(高危HPV分型、液基细胞学结果);④阴道镜指标(转化区类型、病变可见性、是否行宫颈管搔刮术);⑤手术指标(手术方式、锥切标本尺寸);⑥病理指标(术前CIN级别、腺体累及、术后切缘状态)。 电子数据采集系统(EDC):?两名研究者将独立从上述医疗信息系统中提取数据并录入至加密的Excel数据库。录入完成后,由第三名研究者(高级职称)随机抽取20%的样本进行交叉核对,以确保数据准确性。数据逻辑核查(如范围检查、一致性检查)将使用R软件(版本4.2)或SPSS 26.0进行。最终数据库存储于医院内部受密码保护的服务器,仅研究团队成员可访问。无基于互联网的EDC系统(如ResMan)被使用,因本研究不涉及前瞻性数据收集和中央随机化。 缺失数据处理:?缺失率<5%的关键变量将采用完整病例分析;缺失率5%-10%的变量采用多重插补(MICE);缺失率>10%的变量将考虑剔除或仅作描述性报告。

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

1. This study is a retrospective study, with data sourced from the electronic medical record system (HIS), laboratory information system (LIS), and pathology information system of Wuhan Fourth Hospital. 2. Case Record Form (CRF): The researchers will design a standardized electronic data extraction form (in Microsoft Excel format) containing the following variables: (1) Demographic indicators (age, years since menopause, body mass index, smoking history); (2) Clinical indicators (hypertension, diabetes); (3) Preoperative examinations (high-risk HPV genotype, liquid-based cytology results); (4) Colposcopy indicators (type of transformation zone, visibility of lesions, whether cervical canal curettage was performed); (5) Surgical indicators (surgical method, size of conization specimen); (6) Pathological indicators (preoperative CIN grade, glandular involvement, status of postoperative margins). 3. Electronic Data Capture System (EDC): Two researchers will independently extract data from the above medical information systems and enter it into an encrypted Excel database. After data entry is completed, a third researcher (senior title) will randomly select 20% of the samples for cross-checking to ensure data accuracy. Data logic checks (such as range checks and consistency checks) will be performed using R software (version 4.2) or SPSS 26.0. The final database will be stored on a password-protected internal hospital server, accessible only to research team members. No internet-based EDC systems (such as ResMan) will be used, as this study does not involve prospective data collection or centralized randomization. 4. Handling of Missing Data: Key variables with a missing rate of < 5% will be analyzed using complete case analysis; variables with a missing rate of 5%-10% will use multiple imputation (MICE); variables with a missing rate of > 10% will be considered for exclusion or reported descriptively only..
