Cohort study 

研究目的:

本试验采用小样本、前瞻性、探索性、队列研究设计,以cT1N0M0(不符合内镜切除适应证)胃癌患者为研究对象,对内镜下早期胃癌全层切除联合腹腔镜区域淋巴结清扫术的技术方案进行进一步的优化和定型,从而获得稳定成熟的技术方案;同时评价该术式的手术风险、术后并发症发生率、肿瘤学安全性(及学习曲线)、临床疗效、术后生活质量和医疗资源利用情况。,从而为后续确证性多中心研究的样本量计算、核心结局选择以及可行性收集关键信息。  

Objectives of Study:

This trial employs a small-scale, prospective, exploratory cohort study design. It targets patients with cT1N0M0 gastric cancer who do not meet the indications for endoscopic resection. The primary objective is to further optimize and standardize the technical protocol of Endoscopic Full-Thickness Resection (EFTR) combined with Laparoscopic Regional Lymph Node Dissection, thereby establishing a stable and mature surgical technique.

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):

研究将在主要研究结果文章正式发表后的 6 个月内(预计日期:2028-12-31,具体以实际发表日期为准),将去标识化的个体参与者数据、数据字典、研究方案及统计分析计划上传至公共数据存储平台 Dryad (网址:https://datadryad.org) 或 Figshare (网址:https://figshare.com)。届时数据将通过 DOI 链接公开访问,或需提交简短的数据使用申请后获取。

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

De-identified individual participant data (IPD), the data dictionary, the study protocol, and the statistical analysis plan will be uploaded to the public data repository Dryad (https://datadryad.org) or Figshare (https://figshare.com) within 6 months after the formal publication of the primary results manuscript (anticipated date: 2028-12-31; subject to the actual publication date).

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:

本研究采用混合数据采集与管理模式。 病例记录表 (CRF):实验室检查数据及影像学结果直接从医院信息系统 (HIS/PACS) 导出并保存为电子源数据;临床评估、不良事件及生活质量量表等数据采用纸质 CRF记录,由研究者签字确认。 电子采集和管理系统 (EDC): 数据库构建:使用 Microsoft Excel (Office 365) 建立结构化数据库。 录入质控:严格执行双人双录入 (Double Data Entry) 制度。由两名经过培训且独立的数据录入员分别将纸质 CRF 数据录入两个独立的数据库文件中,利用 Excel 公式或比对工具自动识别差异。 差异处理:对于不一致的数据,由第三方可信人员核对原始纸质 CRF 进行仲裁修正,直至两套数据完全一致后合并为最终分析数据集。 逻辑核查与安全:数据库预设数据验证规则 (Data Validation) 和逻辑检查公式(如极值限制、逻辑跳转检查)以拦截录入错误。同时,实行严格的版本控制,所有原始录入文件与修正记录均归档保存,确保数据修改可追溯(模拟稽查轨迹),并定期进行加密备份。

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

This study employs a hybrid data collection and management model. Case Record Form (CRF): Laboratory test results and imaging data are directly exported from the hospital’s information systems (HIS/PACS) and retained as electronic source data. Clinical assessments, adverse events, and quality-of-life questionnaire data are recorded on paper CRFs, which are signed and confirmed by the investigators. Electronic Data Capture (EDC) System: Database Construction: A structured database is established using Microsoft Excel (Office 365). Entry Quality Control: A strict Double Data Entry protocol is implemented. Two independent, trained data entry personnel separately input data from the paper CRFs into two distinct database files. Discrepancies between the two datasets are automatically identified using Excel formulas or comparison tools. Discrepancy Resolution: For any inconsistent data points, a third-party verifier reviews the original paper CRF to arbitrate and correct the errors. This process continues until both datasets are identical, at which point they are merged into the final analysis dataset. Logic Checks and Security: The database incorporates predefined Data Validation rules and logical check formulas (e.g., range limits, logical skip patterns) to intercept entry errors. Furthermore, strict version control is enforced. All original entry files and correction logs are archived to ensure data modifications are traceable (simulating an audit trail), and regular encrypted backups are performed.
