研究目的:

明确pCLE在胃早癌分化程度判断中的作用,旨在在病理前实现对病变的“光学活检”,有助于胃早癌治疗方式选择。  

Objectives of Study:

To clarify the role of pCLE in determining the differentiation degree of early gastric cancer, aiming to achieve an "optical biopsy" of the lesion before pathological examination, thereby facilitating the selection of treatment strategies for early gastric cancer.

药物成份或治疗方案详述:

纳入标准:

1.病变部位在胃 2.经病理证实为早癌的患者; 3.在内镜下治疗及手术之前行共聚焦内窥镜检查; 4.内镜系统中保存并可调取完整离线pCLE图像、放大内镜图像;

Inclusion criteria

1. The lesion is located in the stomach. 2. Patients with pathologically confirmed early gastric cancer. 3. Confocal endoscopy performed before endoscopic treatment or surgery. 4. Complete offline pCLE images and magnifying endoscopy images are stored in the endoscopy system and can be retrieved.

排除标准:

1.病变部位在除胃之外的其他消化道部位、进展期癌患者 2.不适合或不同意使用共聚焦检查的患者; 3.病理结果不符合胃早癌诊断; 4.pCLE图像缺失,放大内镜和pCLE图像无对应;

Exclusion criteria:

1. Lesions located in other parts of the digestive tract other than the stomach, or patients with advanced cancer. 2. Patients who are unsuitable for or do not consent to undergo confocal examination. 3. Pathological results that do not meet the diagnostic criteria for early gastric cancer. 4. Missing pCLE images, or lack of correspondence between magnifying endoscopy images and pCLE images.

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:

本研究采用纸质病例报告表(CRF)采集原始数据,由两名经培训的研究人员独立录入电子数据管理表格,并进行交叉核对,如有差异则追溯原始记录予以更正。数据经去标识化编码后存储于加密专用电脑,访问需经主要研究者授权,且定期备份,以确保数据质量和受试者隐私保护。

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

In this study, original data are collected using paper-based Case Record Forms (CRFs). After data collection, two trained researchers independently enter the data into an electronic data management spreadsheet, followed by cross-checking. Any discrepancies are resolved by referring back to the original records for correction. The data are then de-identified through coding and stored on an encrypted dedicated computer. Access to the data requires authorization from the principal investigator, and regular backups are performed to ensure data quality and protection of participant privacy.
